Dehumidifiers buyer's guide

Having too much moisture or a high level of humidity in your home can be damaging for your health and your house.

Humidity is created in the home from every day activities such as having a shower, cooking or running dishwashers and washing machines. This in turn causes condensation and damp that can affect the infrastructure of your house - not to mention mould, peeling wallpaper and unpleasant odours.

Having humidity levels of more than 50% in the home can also aggravate allergies and asthma. A dehumidifier works to maintain humidity levels by drawing moisture from the air, keeping your house and health in check. The recommended levels are 35%-45% in summer and 25% in winter.

Here at Crowdstorm we love making sure you’re getting the best deal for your money. We’ve scoured the web to bring you the best offers and prices so you’re sure to find the best dehumidifier for your home and needs.

Types of dehumidifier

You'll find two main types of dehumidifier on the market:

  • Compressor: These models first freeze the air as it enters the unit to capture it, then defrost it to capture the water in the tank. The use of a compressor means they essential operator like a fridge, meaning not that as ecological as desiccant models. 
  • Desiccant: These use a honeycomb of zeolite (volcanic rock) to absorb the water as it passes through, then heat the zeolite to deposit the water in the tank. These have much improved in recent years and are becoming the dehumidifier of choice for many.
  • Car dehumidifier: If you have trouble with mould in your car, or have problems with condensation in winter, these handy bags can be the answer to your problems - and you can pick them up for less than £15.
  • Clothes drying: While it's tempting to pop your clothes on the radiator and turn the heating on, using a dehumidifier in the laundry room can get the job done just as well and at a fraction of the price - and in winter, your heaters are clear of damp clothes that trap all the heat.

What are the main considerations when buying a dehumidifier?

These are decisions every buyer needs to consider before starting to compare models.

Budget: Have a think about cost and your budget. Solid budget models start at around £50, while de-humidifiers costing more than £200 are now common. Cheaper models will have less features and can often be less effective. Many more expensive dehumidifiers will also have a larger water capacity, meaning they need to be emptied less often.

Capacity: Common sizes are 10l and 20l, with larger capacity models work faster and more efficiently than smaller ones. Depending on the size of unit they hold varying amounts extracted water, with better models being able to extract a lot more moisture each day. This can have a big effect on how often you'll have to empty your unit, so think carefully about how these numbers stack up: for example, a dehumidifier that can draw 20 litres of water per day but only has a four-litre capacity will need to be emptied five times a day if operating at full power.

Size: The more water a dehumidifier can hold the bigger it's going to be, so you'll need to weigh style/location versus portability/practicality. It's common to find models that are around two feet high, and sometimes as deep, so think carefully about the room they'll be going into. On the plus side, if it's a smaller room the chances are you'll able to use a smaller dehumidifier.

Noise: Dehumidifiers can be noisy, and that dull hum could get extremely irritating if the unit is in a room where you spend lots of time. Shop for a dehumidifier with a variety of levels/settings; this way you can put them on a lower level when using the space. Larger models also tend to be quieter, which is great if your dehumidifier is situated in a bedroom or living room.

Energy efficiency: Dehumidifiers are not the most energy efficient of machines, and the larger units can be extremely expensive to run. If energy efficiency is important to you be sure to check for energy efficient features and controls such as automatic switch off when the tank is full, intelligent defrost and smart controls. 

Dehumidifier extra features

With the basics taken care of, these are the bells and whistles it's worth investigating to make sure you get the best dehumidifier your money can buy:

  • Air purifier: Some models double as air purifiers, helping allergy sufferers and asthmatics as well as eliminating the likes of second hand smoke.
  • Carbon filter: These will also help filter out pet and cooking odours.
  • Display: Dehumidifiers with a display feature easy-to-use digital controls, while often offering extra benefits such as a timer.
  • Humidistat: Shows you the current level of humidity in the room. 
  • Ionizer: This is a form of air purification that helps trap airborne particles, such as dust.
  • Remote control: Or, as my mum used to call them, the 'button pusher'...
  • Timer: Lets you set the de-humidifier to keep the room dry in organised stages, by setting it to go off at various times of te day.
  • Washable filter: Can be washed and replaced, saving you money on having to constantly buy new disposable filters.
