The best dehumidifiers can make battling dampness, mould, mildew, and condensation a breeze. I've tested and reviewed every model from Meaco through to ProBreeze to find dehumidifiers that will get perfect results without sending your energy bills sky high.

The first time that I invested in a dehumidifier, I didn't know my refrigerant from my desiccant. In case that's you too, the former uses condensation to take moisture from the air (better for rooms with high humidity) and the latter uses absorption (better for quick results in colder rooms). Now, after years of using my MeacoDry Arete One, I've become a bit of a geek.

I'm never one to gatekeep, so I share all my dehumidifier secrets with you. From how to use a dehumidifier in the winter right through to what I wish I knew before I bought a dehumidifier and dehumidifier mistakes that lots of people make. Most importantly, I've been working on reviews for every dehumidifier that you could possibly consider buying.

I've been testing all of the best dehumidifiers on the market, throwing every model in mildewy bathrooms, humid laundry rooms, and dripping basements to test how effective they are in all rooms around the home. My aim is always to keep the humidity of any room in our house between 40-60%, which is the target range for healthy, clean air. The only dehumidifiers that passed my tests are right here, in this guide. So, whether you're looking for a quiet dehumidifier for your bedroom or an industrial piece of kit for an older home, these are the ones you can trust.

The MeacoDry Arete One is probably one of the most famous dehumidifiers around. Having used it in my home for months, I can promise that it's reputation for robustness, speed, and a reasonable price tag is well founded.

You can pick up the Arete One in two sizes, 10L or 20L. Most homes will only need the 10L model, which Homes & Interiors expert Amy Cutmore tested in her home. It's smaller, of course, and Amy found it easy to move around and use. "I love how it looks," she says, "the matte off-white and charcoal finish give the Meaco a Scandi-style that is about as handsome and unobtrusive as a dehumidifier is going to get."

It's not just a pretty face though. This boasts some impressive extraction timings and capacity. Amy managed to maximise the 24-hour extraction rate of her model, removing nearly 10L of water from the air in her home. I managed to reduce the humidity in my (dripping) basement by a full 20% overnight. And, even better, it works almost silently. Both Amy and I found that the night mode (which turns the fan to low, kills the lights, and stops the buttons from bleeping) was quiet enough to let us enjoy some deep sleep.

It's not just the fact that this can extract moisture from space as big as 42m², it has lots of other, subtle, but useful features integrated too. There's a hidden handle that pops up from the control panel and a handy cord tidy which keeps the two-metre-long cable in check when the unit is not in use.

This worked incredibly well when it was drying clothes, in my cellar, and in the bedroom. However, it's a refrigerant model, so if you're going to put your dehumidifier in a garage or colder space, you might want to shop around a little more.

The best dehumidifier for bedrooms

2. De'Longhi DEX212F Tasciugo AriaDry Multi Dehumidifier

Best for bedrooms

Specifications

RRP : £254.99
Tank capacity: 2.1 litres
Maximum extraction per day: 12 litres
Modes : 3 settings for environment humidity level, plus laundry function

Reasons to buy

+
This machine is very quiet, so it's ideal for bedrooms
+
The setup and usage is extremely intuitive, so ideal for households with less tech knowledge
+
Can filter dust and allergens too, making it a great multi-tasker


Reasons to avoid

-
On the heavy side, difficult to move around as a result
-
It has a shorter cable than other full-size models (1.5 metres) which means you'll need a plug near to where you want to use it

There isn't any other dehumidifer that comes close to the noise levels (or absence, as it were) of the De'Longhi. It's so quiet that I wasn't even sure it was running. You could sleep with this on, you could watch TV with this on. I reckon you could even meditate with this on. It's certainly the best dehumidifier for a bedroom, by a mile.

The Italian-made dehumidifier is everything you would expect aesthetically. It's slim, sleek, and beautiful, as far as these appliances go. You can use the handle and castor wheels to move the main body around, which very much needed. The De'Longhi is heavy.

At first, I thought it was going to be complex, since there are a fair few more buttons than most dehumidifiers have, but it's really straightforward. there's essentially one laundry mode and three dehumidifying settings, and a night mode. You get to set a target humidity and once this chosen level has been reached, the machine will stand down until it’s needed again. It'll save money and energy.

Whenever the humidity was reached or the 2.1-litre tank was full, I could empty this really easily. The water is completely contained, avoiding any chances of spilling water on your way to the sink.

There’s even frost protection functionality here too, making it safe to use in colder environments, such as my cellar in the winter. which was handy when we had no heating on during a particularly bitingly cold day.

It’s not all about controlling humidity though: hygiene is another of its concerns, and it has filters for dust and allergens as well as the capacity to neutralize undesirable bacteria to improve air quality in your home.

The best dehumidifier for drying clothes

3. EcoAir Desiccant 8L Dehumidifier DD128

Best for drying clothes

Specifications

RRP: £289.98
Tank capacity: 2.2 litres
Maximum extraction per day: 8 litres
Modes: 3 drying modes, 2 laundry modes

Reasons to buy

+
The really efficient laundry mode helped us to dry clothes and linen in an impressively quick time frame
+
There's a timer function which is great for busy households
+
The handle makes it easy to carry from room to room 
+
There is also an energy saving mode which can help to keep costs down 

Reasons to avoid

This isn't one of the quietest models we tested, so be prepared for a bit of noise

The EcoAir DD128 is a versatile desiccant dehumidifier – while great for colder spaces, it’s also efficient in the home (and especially around laundry). Amy used this for a month in her home and said "it's incredibly powerful. In fact, I noticed it collecting moisture much more quickly than most other models that I've tested." She also added that the long cord made it really convenient to position around her homes.

The mode that really stands out to Amy is the laundry setting. "It's a really special feature," she says, "as well as capturing the moisture it also blew out warm air, meaning my load of washing was dry in a matter of hours as opposed to days. The timer function meant I didn’t have to leave it running all night to get those clothes dry either – it can be set to power down in two, four, or eight hours."

There’s a decent 2.2-litre tank on this model, which is easily removable from the side of the unit for emptying and even has a built-in handle for ease. But also, if you want to leave it for long periods of time, it comes with a handy hose for continuous drainage.

Amy's few criticisms are that this is not the most intuitive to use, although that’s to be expected with a model that offers lots of different settings. She got the hang of it after going over the instructions a couple of times, but that's two more times than she had to look at the instructions for her Meaco and Pro Breeze dehumidifiers.

It's also worth noting that the fan is quite loud on all but the economy setting (which is designed for maintaining air quality once optimal dryness has been reached), meaning Amy felt this wasn’t one for the living room. But there’s no denying it’s a real workhorse and has serious speed and power. Plus, it has an anti-bacterial filter and Ioniser to purify the air.

The best dehumidifier for bathrooms

4. Wood’s Dehumidifier MDK26

The best dehumidifier for bathrooms

Specifications

RRP: £409
Tank capacity: 4 litres
Maximum extraction per day: 25 litres
Modes: Automatic

Reasons to buy

+
Sturdy and feels like it's made to last
+
Efficient and powerful, drawing in a lot of moisture over a short time period 
+
Emits low-level warm air which helped dry our laundry quicker than usual

Reasons to avoid

-
Slightly heavy to move around the home

Woods makes some seriously impressive dehumidifiers, some are even close to industrial. In spite of its smaller stature, this is one of my favourites. It cleared condensation in my bathroom in record time and didn't generate much noise or demand much power in the meantime. What else would you expect from the revered Scandi brand?

The reason that I would use this in my bathroom isn't just for its power and speed though. The Woods is also super slim, making it easy to slot into smaller spaces and nooks nearby the bathroom. Even though it's relatively heavy, I found this really easy to move around thanks to its in-built carry handle. Although, it's worth noting that this doesn't have wheels as some other models do, so this might suit homes with more carpet than solid floors

With just a handful of touch buttons, the interface is straightforward to use, allowing for quick programming and slick switching between functions when needed. You simply set the humidity to your preferred level and make use of the timer if you like, and away you go.

It emits a low hum, but nothing that would disturb you during the day. Come the evening there isn't a night mode which means you’ll be falling asleep to the light buzzing of an electronic device which I could personally do without. It's better company in the daytime when you're not looking for some peace and quiet, a bit like me.

The best compact dehumidifier

5. Russell Hobbs Fresh Air Pro Compact 2-in-1 Dehumidifier and Air Purifier

Best compact dehumidifier 

Specifications

RRP: £99.99
Tank capacity: 1 litre
Maximum extraction per day: 750ml 
Modes: 3 speed settings

Reasons to buy

+
Stylish appearance to have on show and ideal for modern homes
+
Lightweight to manoeuvre, so really easy to move around if you intend on using it in a few different spaces
+
Compact in size, so not imposing if used in living areas
+
Purifies as well as dehumidifies for cleaner air too

Reasons to avoid

-
Limited capacity so requires emptying often in more damp areas
-
Not ideal for large rooms as it doesn't have the power to cover a large square meterage 

This stylish dehumidifier is one of the least imposing models I've tested. It’s sleek and contemporary and blended into the background of my home without me even noticing it. It could be mistaken for a speaker, which makes staying and storing this dehumidifier easy. Another boon of its tiny stature is that you can move it around the house easily. I have lots of stairs at home and taking this to each different test (laundry, overnight, the cellar) was by far the nicest. The only downside of the size is that it limits the capacity of the water tank. I think it's a reasonable payoff anyway.

Its control panel is kept simple with three fan speeds – I’d barely glanced at the instructions before it was happily whirring away. As you’d imagine, the more powerful settings are noisier, but the lowest is still efficient and quiet enough to have running in living spaces where you're having conversations or watching TV.

I found the Russell Hobbs worked best in the small and medium-sized rooms of our house where there was general winter dampness, although the cable struggled to reach some higher sockets in my kitchen – it is modest, though not disastrous, at 1.5 metres long. If you have larger rooms, a more severe damp issue, or masses of laundry to get dry, you might need something just a little heftier.

The best dehumidifier for damp areas

6. ProBreeze 20L Dehumidifier 

Best for particularly damp areas

Specifications

RRP: £249.99
Tank capacity: 5.5 litres
Maximum extraction per day: 20 litres
Modes: Normal, low power, high power, laundry

Reasons to buy

+
Large capacity means this is ideal for bigger homes or for open-plan living
+
Impressive daily extraction potential collects a huge amount of water
+
The 24-hour timer allows you to programme the machine how you like it over the course of the day and night
+
The child lock safety feature is great if you have junior family members

Reasons to avoid

-
The trade-off for such a powerful machine is that it does feel a touch imposing
-
Similarly, it's not very easy to carry so wouldn't suit anyone with mobility issues

I'd heard all about the Pro Breeze before I even got around to testing it. Roy Jaramillo, the owner of Amazing Air Solutions, recommended them as "a more budget-friendly but effective brand. Their dehumidifiers are really great if you want to maintain humidity levels around 40%, even if you've got tougher tasks to tackle."

Having used it for a month, I can say that this is everything you might expect from a budget-friendly brand. The 5.5-litre tank is about average for domestic dehumidifiers. However, if you attach the hose, it's able to extract 20 litres of moisture a day from the air (the most of any model I tested). There's also an inbuilt sensor that allows you to set your desired air humidity and save on energy (the machine will kick in only when needed to maintain it), a 24-hour timer function, laundry mode, and – our favourite feature of all – a child lock.

It's easy to empty and effective to use, but it's not without some drawbacks. For a start, the menu offers lots of customizable settings, which is great for efficiency and versatility, but means reading those instructions is a must. It is also the bulkiest model I tested – both in terms of size and weight. It was tricky for me to lift up a set of stairs, but it does have a fold-out handle and wheels on the bottom. If no stairs are involved, moving it from room to room was a piece of cake. The generous cord length also helped up its convenience too.

The best value dehumidifier

7. MeacoDry ABC 12L

Best value

Specifications

RRP: £169.00
Tank capacity: 2.6 litres
Maximum extraction per day: 12
Modes: 3 fan speeds, laundry mode

Reasons to buy

+
Reasonably priced for the multiple, effective functions
+
Compact and attractive, perfect for small and large spaces
+
Simple to use, especially for first-time users
+
Efficient and cheap to run, so it won't drain your utilities
+
Can halve the time it takes to dry clothes

Reasons to avoid

-
Relatively noisy, so can't be used in the bedroom
-
Heavy and cumbersome, so you won't want to move it around

MeacoDry is a big name in the dehumidifier world, so it's no surprise that they make the best dehumidifier for laundry (as well as the best dehumidifier overall). Amy, our expert tester, described this as "the perfect size for a three-bedroom home which has light condensation." It didn't solve the damp issues in the room but made some considerable headway towards clearing it.

Where the ABC 12L stands out is as an indoor dryer. Amy tried drying clothes which would normally need 14-36 hours and found that the very same clothes were iron dry within six hours. Proof that the specialised laundry setting more than delivers. Plus, there's an auto-off function, so that when the tank is full the Meaco won't keep running and draining your energy (and your wallet).

Amy offered a few words of warning with respect to the MeacoDry: "it was impressive and energy-efficient, but I also found it pretty cumbersome and heavy. I also found that it's much too loud to use in your bedroom. On the highest fan setting, I recorded 59 dB of noise. On the lower setting, the noise was comparable to my dishwasher or a low conversation."

The best dehumidifier for energy efficiency

8. Avalla X-150 dehumidifier

Most energy efficient

Specifications

RRP: £260
Tank capacity: 3.5 litres
Maximum extraction per day: 16 litres
Modes: Automatic, sleep and fan

Reasons to buy

+
Great size for a family home with a good tank capacity
+
Two-year warranty allows you to buy with confidence 
+
A quiet sleep mode allows you to turn down the volume come nighttime 
+
Additional hose attachment allows for continued use which is very useful in high-traffic areas like utilities or bathrooms

Reasons to avoid

-
You can still hear the night mode while it's running, so this might not be suitable for light sleepers

Rosie, one of our expert testers, said "the Avalla is compact and stylish, in so far as similar models go. The sleek tower design is small enough to fit in most spaces around my house."

For the most part, it’s just a plug-in-and-go job, but this particular dehumidifier also comes with a two-metre long hose which needs to be fitted separately if you’d like to use it. It’s a simple feature but it is hugely helpful in spaces which require extra attention, like utilities or bathrooms, allowing you to have the machine on continually over the course of the day or night.

Despite its neat stature, it has a large enough capacity to deal with up to 46m² at any one time. However, Rosie found it most efficient in smaller spaces where it drew in a surprising amount of water in just a few hours. This will fluctuate with the levels of humidity in any one environment, but the tank was full after half a day and needed emptying.

Rosie said that this was particularly effective in her old bathroom. "I don't have an electric extractor in here," says Rosie, "normally I would see water running down the walls and condensation pooling on the shower walls and the windows. Howeverm this helped keep the air much clearer and eliminated the most visible moisture in under an hour. "

The clothes drying feature also more than halved the time needed for clothes to be ready to fold, compared to leaving them to air dry normally. Not only is this great in terms of time-saving, it also apparently saves up to 93% on energy bills, according to Avalla.

9. ProBreeze 1500ml Mini Dehumidifier

Best dehumidifier under £50

Specifications

RRP: £49.99
Tank capacity: 1500 ml
Maximum capacity: 500ml per day
Modes: One basic setting

Reasons to buy

+
Really well priced, especially for how well it performs
+
Super quiet, so you could run it in the bedroom when you're sleeping
+
Costs 1p per hour to run
+
Lightweight and easy to move around

Reasons to avoid

-
Not suitable for larger spaces
-
Pretty basic if you have demanding damp needs

I don't always recommend going for the cheaper dehumidifiers on the market, but this is one of the few products that is probably worth more than the retail price. It's compact, efficient, and extremely quiet. For less than £50, it's pretty perfect.

If I was to sit this running alongside the MeacoDry Arete One (my top pick) it would, of course, not quite compare. The capacity is really good for its size, but it's not much compared to the average, 10L model. If you see this dehumidifier for what it is – a basic model that's designed to work in rooms up to 2200 cubic feet (220 sq. ft) – you'll see that it's amazing at what it promises to do.

What's even better than the small footprint and even smaller retail price is that this costs just 1p per hour to run. Given that it's effective at extracting moisture from small bathrooms and laundry rooms, it's a bargain. My plan is to keep this running in my wardrobe, which has developed an unforeseen damp issue. It seems to be doing the job so far, but I'll keep you updated.

So, it's simple, affordable, and compact, why shouldn't we all buy it? The extraction rate is great for small spaces, but it's also pretty basic. It's not ready to tackle any serious issues (don't stick it in a damp basement, for example). Other than that, this tiny dehumidifier lives up to ProBreeze's big reputation.

Our experts are in the process of testing it and we'll give you a full review as soon as we're finished using it.

How we tested the best dehumidifiers

There is a huge range of dehumidifiers on the market from a host of different brands. We sifted through countless models in our research to find the most effective, efficient, and reliable – then tested our shortlist.

First, we assessed customer reviews from retail sites and reviews from other experts around the internet. Then we investigated specific brands and the ranges they offer, looking for their specialisms, gauging their reputation, and sizing up customer satisfaction.

To ascertain how effective each dehumidifier model proved, we used each one for a range of tasks over time, and looked at:

  • Ease of use: How easy each dehumidifier was to set up. Did it come with instructions, and how long did it take to read and work out how to use it?
  • How many functions did it offer: Did it only offer different speed modes or a laundry setting?
  • Value for money: Is it worth the price tag, or could you get an equal experience for less money? Do the more expensive models offer a better experience?
  • How easy it was to clean and store: We always want to know how to clean a dehumidifier to keep it well-maintained, so we looked at how straightforward that was for each model. We also looked at how easy they were to empty plus if the components were easy to remove for cleaning.

Although our top dehumidifiers are listed above, we're constantly assessing and testing the latest releases to make sure we're recommending the very top products on the market. Read our full explainer of how we test dehumidifiers for more about our in-depth process.

FAQs

Probreeze dehumidifier at home, drying laundry

This is the Probreeze dehumidifier in Amy's home, drying laundry

(Image credit: Future)

What should I consider when buying a dehumidifier?

So why should you buy a dehumidifier? As well as the environment in which you plan to use your dehumidifier, there are several other things to consider before you invest.

For instance, will it stay in the same spot, or do you intend to move it from room to room? Some models are far more portable than others, so pay close attention to the size and weight of the appliance.

And think about where it’ll be used and stored too; you don’t want to be tripping over it constantly if it’s a heftier model or have nowhere to pack it away in the summer months when you may not need it.

Size isn’t the only potentially imposing characteristic of a dehumidifier – they all make noise while operating. If it’s going to be used in a living space, consider how loud of a hum or whirr you can realistically live with.

While dehumidifiers can help keep energy bills down by negating the need to dial up the heating or succumb to the tumble dryer, there will, inevitably, be an initial outlay. So when you’re deciding how much to spend on a dehumidifier, be prepared to play the long game. Net savings will amass gradually over time and use – so if you don’t think you’ll realistically rely on your new appliance very often or plan to still use a tumble dryer, a smaller, more affordable dehumidifier might be the best value for you.

Tony Abate, a certified environmentalist and CTO at AtmosAir Solutions, says 'the unit should operate with a humidistat too, so you can set your desired humidity (around 40% is ideal) and the unit will automatically operate when dehumidification is needed. It's also helpful if your unit has a removable container connected to an auto cutoff so that it's easy to empty and won't overflow.'

It’s also important to try and work out where your dampness is coming from, too. Modern dehumidifiers have different modes so, for instance, if drying endless loads of laundry (we can relate) is the cause of all that excess moisture, looking for a model that has a specially designed laundry mode is wise.

How much should I spend on a dehumidifier?

While there are some exceptions, generally in life you get what you pay for. During our various rounds of testing, there was the odd model which stood out for offering good value alongside high performance – like the Russell Hobbs dehumidifier above – but it’s worth keeping in mind that cheaper versions are typically smaller and less robust, meaning they lend themselves to individual rooms or spaces rather than whole apartments or houses.

Depending on your set-up, you might want to keep costs down and just use a neater dehumidifier in a defined area like a cupboard or bathroom. For larger or busy households, where you might want the machine to help with drying clothes and keeping multiple spaces dry, then we’d guide you in the direction of spending a little extra to get a solid performer that will both make a noticeable difference and be able to handle the pace for years to come.

Check out the latest dehumidifier deals to make that investment more worthwhile.

How do dehumidifiers work?

When trying to understand how a dehumidifier works remember there are two main types of dehumidifiers: compressor (or refrigerant) and desiccant. These both remove moisture from the air using different methods and are designed for different environments.

Compressor dehumidifiers (which you might also find labelled as refrigerant), work by sucking in air with a fan and passing it over a cold surface (think metal coils or plates). This creates condensation inside the unit, which then drips into the water tank. This method is reliant on the air that’s drawn in being warmer than the cold surface inside, otherwise, condensation won’t form and the liquid can’t be extracted. Compressors, then, are popular for warmer spaces where central heating is used – think bedrooms and living rooms.

Meanwhile, desiccant dehumidifiers capture moisture using an absorbent material. The liquid that’s been sucked up then trickles down into the tank. This type of appliance doesn’t rely on the air being a particular temperature, meaning they’re great for colder spaces that are perhaps not well insulated or heated, like conservatories, basements, and garages. They do tend to use more energy than compressor types, though.

Do dehumidifiers save money?

A dehumidifier is the most effective way to reduce excess moisture in your home. If you don't have a dehumidifier, you're probably exercising a few inefficient, inconvenient options at the moment.

Lots of people try ventilating there home, which can be a great solution if you're suffering from musty humidity. However, if it's cold outside, cracking your windows isn’t a tempting prospect as you’d end up losing precious heat and likely pushing up your energy bills. Similarly, having cold showers and during your clothes outside aren't always practical when the weather is unpredictable, cold, and damp.

Speaking of heat, cranking that thermostat up helps to dry out damp too, but with the recent price hikes for gas, this is far less of an affordable option than it once was – how much it costs to run a dehumidifier being a more affordable option.

If most of your dampness comes from airing laundry, you might also be thinking about investing in a tumble dryer – although these start at around the same price as a dehumidifier and it’s widely agreed they cost much more to run. But there are alternative ways to dry laundry, one of which is to use a dehumidifier to help dry clothes.

So, especially when compared to other methods of damp prevention and treatment, dehumidifiers are sound investments. Plus if you manage to secure a deal you can pick up one the best for less.

Do you run a dehumidifier in the winter?

Whether or not you need to use a dehumidifier in the winter really depends on the climate you’re living in. If it gets cool and damp then it can be useful to run one for a little while each day, helping to maintain a healthy average humidity level of around 30-50% in your environment. Here are some ways running a dehumidifier in winter can be beneficial:

  • Banish window condensation caused by cool outdoor temperatures
  • Keeping humidity levels healthy will help your heating systems to run efficiently
  • Help your laundry to dry quickly

Do dehumidifiers use a lot of electricity?

We've already covered a fair amount of this in our answer for 'do dehumidifiers save money?'. If you want the short answer, yes, they probably do.

Speaking generally, dehumidifiers use 300-1,500 watts of electricity per hour. Of course, this will depend on the size, capacity, energy efficiency, and usage of your dehumidifier. If this is something you're conscious of, check the wattage rating of the dehumidifier you're interested in and multiply it by the number of hours you'll need your dehumidifier to operate for each day.

Most new models come with energy-saving features, which includes auto-shiyt off and efficient compressor technology. You can also give your dehumidifier a helping hand, by looking for the source of your humidity, ventilating your room, and insulating your space well.

The alternative ways in which you'll either dry clothes or get rid of humidity in your room will end up pushing up your energy bills. You'll either have to up the temperature on your thermostat; invest in a good dryer; and open the windows inside (losing heat from your home).

What size dehumidifier do I need?

Choosing the right size of dehumidifier for your room will depend on several factors, namely the size of your room, the level of humidity, and the airflow and temperature of your room.

If you're trying to work out which one you need, start by calculating the square footage of the area that you want to dehumidify. Most models (and our reviews) will give you guidance on what sort of area they can cover.

If you want to assess the levels of humidity in your room, you can use a hygrometer to get a reading of your room. Then, look at the capacity of your appliance. A small capacity dehumidifier will be able to remove 30-40 pints per day and larger ones will be able to handle 70 pints or more.

How do I clean a filter on a dehumidifier?

If you've chosen to invest in one of the best dehumidifiers on the market, you'll want to keep it clean. We've broken down the process into five easy steps for cleaning a dehumidifier.

Cleaning the filter specifically will depend on the model that you choose. Essentially, your goal is to remove all the dust and debris from inside, so that air can flow through freely. Experts recommend carefully vacuuming or using a warm, damp cloth to wipe dirt away. Once this is done, dry the filter and put it back into the dehumidifier.

If you have a small model, that is difficult to clean, some experts recommend using a toothbrush with small bristles that can reach hard-to-clean areas. Experts will also note that dual-function dehumidifiers come with HEPA filters which will need to be replaced every six months.
