Dehumidifier Buying Guide

Protect against damp, mould & condensation in your home.

Any home can benefit from a dehumidifier, and if you’re looking for a new dehumidifier, this handy guide aims to help you find the best dehumidifier for your purpose and budget.

Daily tasks such as cooking, showering/bathing and drying laundry all have an impact on the humidity level of your home. In the colder months, moisture naturally condenses onto walls, windows and inside your cupboards, leading to damp areas.

Dehumidifiers help to remove excess moisture in the air to combat dampness, mould and condensation. They also help to reduce allergens and clean the air, creating a healthier and more comfortable environment for you and your family.

Reasons to buy

Drying Clothes

Many of our dehumidifiers feature a 'laundry mode' to help dry clothes quickly and efficiently - even more than a tumble dryer. Plus, the smaller the room, the faster your clothes will dry.

Damp

Cooking, showering and drying clothes all increase humidity levels in your home. Without a dehumidifier, dampness ends up in the walls, ceilings and floors, which could create future problems. All our dehumidifiers prevent excess airborne moisture from settling, leaving a clean, dry environment.

Flooding

A dehumidifier can be vital for saving your property from further damage after a small flood. We advise choosing a commercial dehumidifier with a high extraction rate for the best results.

Health & Allergies

Many units support the use of HEPA and carbon filters to capture contaminants like dust and allergens, leaving behind fresh, filtered air. Premium models use UV light and an ioniser for advanced protection.

Save money

A dehumidifier makes your home feel warmer, which otherwise would have felt cold in damp areas, allowing you to lower the thermostat and heat your home for less. Pick a smart dehumidifier for even further savings with smart app scheduling.

Features to Consider

Laundry mode

Laundry mode

Some dehumidifiers feature a 'Laundry mode' that can significantly reduce the drying time of damp laundry indoors. This clever little feature also benefits your energy bills, as it's more efficient than using a tumble dryer or central heating alone.

Enjoy complete control over humidity - a humidistat checks the moisture level in the air so your dehumidifier can match your desired level.

Smart connectivity

Smart Wi-Fi connectivity

Automatic shut-down

Automatic shut-down

When the tank is full, some models automatically shut down to prevent overflowing.

HEPA/Antibacterial Filters

Antibacterial/HEPA Filters

Carbon and HEPA filters capture contaminants like dust, dust mites, mould spores and bacteria to control or relieve allergies and irritations.

Continuous Drainage System

Continuous Drainage System

If you wish to run a device continually, you’ll benefit from a built-in hose as this is more convenient than manually emptying the tank.

Popular Types of Dehumidifier

Compressor dehumidifier in living room

Compressor dehumidifiers

This is the most common type of dehumidifier used in the home and is perfect for warmer environments above 10-15°C. Compressor dehumidifiers, also known as refrigerant dehumidifiers, work by drawing humid air over a refrigerated coil using a built-in fan. The cold coil condenses the moisture in the air, turning it into water that is collected in a tank.

Desiccant dehumidifiers

Desiccant dehumidifiers excel in colder climates or temperatures below 20°C, where compressor dehumidifiers may be less efficient. They work by using a desiccant material that naturally and quickly absorbs moisture directly from the air, a bit like a sponge. Choose a desiccant dehumidifier for your conservatory, cellar, garage, caravan or boat.

Dehumidifier drying laundry

Dehumidifiers for drying clothes

Busy households may want to opt for a dehumidifier with a ‘laundry mode’ or ‘clothes drying mode’. These settings reduce the drying time of damp laundry by absorbing moisture, which is then blown back out at a warm temperature on a high fan speed whilst maintaining optimal humidity.
