Dehumidifier Buying Guide For 2022

You may not have considered purchasing a dehumidifier before. That’s why we’ve put together this buyer’s guide to help you find the best possible options for your specific situations. Got plenty of questions to ask? Don’t worry. We’ll have you covered in our common queries and FAQs section below.

Humidifiers and Dehumidifiers – The Crucial Difference!

Before we get too deep into our guide, it’s worthwhile making a quick distinction. Humidifiers are completely different from dehumidifying units! Humidifiers help to increase moisture in very dry or arid environments, not to filter it out. Therefore, before you accidentally purchase the wrong device, make sure you add that ‘De’ prefix on the front when you search and shop around!

Why Use a Dehumidifier?

This might have been a question we save for our FAQs list; however, we feel it’s important to address on its own. A dehumidifier may not be something you have at the top of your shopping list; however, it could well change your life for the better.

Damp conditions in properties can be a nightmare to fix. What’s more, even when you’ve fixed them, they have a habit of coming back again and again. The best way to get rid of damp and mould, of course, is to remove the moisture from a room. A dehumidifier will work to lower the moisture level, though it’s also worth remembering that it won’t always be a miracle cure.

Do make sure to buy a dehumidifier which you can adjust to fit your particular environment. It can be difficult to narrow your choices down, but in this guide, we aim to make that process a little bit easier.

Types of Dehumidifier

Before we get into the nitty-gritty about features and the like, it’s worth taking a look at the two distinct types of dehumidifier available on the market. These units are generally split into desiccant and refrigerant, and they are designated based on how they work, as well as the benefits they bring.

Desiccant Dehumidifiers

Desiccant models work somewhat like a sponge, as they use material to soak up moisture in the atmosphere around. They are fantastic at reducing moisture in very cold environments, particularly in those of 15 degrees Celsius or below.

This is the edge that desiccant models have over refrigerant counterparts. In this way, they can be generally relied on to reduce moisture in outdoor or non-heated environments, such as sheds and garages. However, it is also worth bearing in mind the amount of energy they use, as they can be expected to run a little more expensively than refrigerant models.

Refrigerant Dehumidifiers

Refrigerant models, meanwhile, actively create cold environments to suck up warm damp. This allows them to turn said moisture into condensation, which is held in a specialist water tank.

These models are seen as more energy-efficient than desiccants; however, as stated, they won’t do so well in very cold conditions. This is because there is a risk of elements within their systems to freeze over if temperatures dip too low.

Energy Expectation

Let’s consider how much energy you can expect these units to use on average. You probably won’t expect to run up bills higher than £20 per year if you are using a generous-sized model and power unit. However, this is only if you stand to use it eight to ten hours a week. Used on a more frequent basis, you are going to see prices spike even further.

As mentioned, certainly make sure to compare and contrast the types of dehumidifier available. It’s worth reading up on what other reviewers and verified buyers have to say, at least so that you can get a feel for energy efficiency before you put any money down!

Finding the Right Size and Capacity

While it may not seem to be a major issue, it is always worth making sure you get the best size of dehumidifier for your space. Too big a model will be a waste of energy, while a system which is too small simply won’t do the job you need it to.

Therefore, you should always be keeping a close eye on the litre capacity before you buy. This goes for both types of dehumidifier, too.
For a small room or space, you will generally be able to get away with a smaller capacity.

However, if, for example, you want to dry out the whole of your property, you’re going to need a major tank. You should also bear in mind that some dehumidifier marketing isn’t exactly based on room temperature use. Therefore, you could be buying too much for what you need.

You may find dehumidifiers with tanks that go all the way up to 20 litres in capacity. Generally, however, smaller models will do the job for smaller needs. We’d recommend always taking a look at verified buyer reviews to get a feel for what may or may not be the best fit for you.

Small dehumidifiers, too, are likely to be less hassle to handle and to carry around. They are convenient and can be used to dry out room after room. Take a look at what’s out there, and see what you think.

Frequently Asked Questions

Let’s consider some of the popular queries asked about dehumidifiers by first-time shoppers.

What Added Features Are Worth Looking For?

You should always look for a dehumidifier which is easy to empty and clean. There is never going to be more hassle than having to get down and scrub hard from use to use. One of the best ways to cater for this is to look for a dehumidifier with a drainage facility. This will make sure that waste water is always washed away from use to use.

Timers, too, are also worth considering. If you don’t have time to oversee your dehumidifier throughout the day, consider setting it to run at certain times. Some models will even connect to Wi-Fi, meaning you can even connect it up to your smart home technology if you wish.

There are even some models with built-in humidistats, which will work out exactly when the air needs to be de-moisturised. This is a very handy function to have, as it means you don’t have to wait for the air to become muggy, or for mould spots to start appearing. Your dehumidifier will simply spring into action. However, do be prepared to pay more for models with these features!

What Affects the Cost of a Dehumidifier?

Generally, tank size and capability will drive up the price of a good dehumidifier. Do also bear in mind that, as mentioned, features will dictate cost. This means that if you really want a Wi-Fi system with auto dehumidifying, you’re going to need to pay a little bit more.

However, it is not always the case that more expensive systems end up being more reliable. You may well find a bargain at a lower price. It’s worth checking industry awards and recommendations on certain systems, and again, verified buyer reviews can and will help a lot.

How Much Can I Expect to Pay for a Dehumidifier?

You can find systems for as little as £30-£40 online. However, as mentioned, you won’t always get the best durability or the most fabulous features for this price tag. You can expect to pay nearly £500 for the best systems, which in many people’s eyes is absolutely worth it. If you have problems with damp and mould regularly, or are at risk from such conditions, it may be an investment you wish to make.

Do also aim for the upper end of the price scale if you need to cover more surface area. Bigger capacity tanks will generally fetch more money, so if you want to cut back on the cash, be willing to keep your capacity small. It’s often worth going for a system with a tank on the smaller side, as again, your exact home conditions aren’t always going to be taken into account.


Buying a dehumidifier for the first time can be tricky, especially if you’re not really sure what to look for. However, providing you purchase a model with a reasonable tank size, a decent amount of features and some trustworthy review scores, you should be onto a winner. Don’t ever fall prey to mould and damp conditions. Do something about it!
