Dehumidifiers, Purifiers & Moisture Absorbers

Frequently Asked Questions

Don’t let moisture in the air put a dampener on the state of your home. Homebase supplies a variety of moisture absorbers, dehumidifiers and air purifiers from the biggest brands to keep out musty smells, polluting particles and potential damage from mould, damp and mildew.

What's the difference between a moisture absorber and a dehumidifier?

Ideal for smaller areas, moisture absorbers can be placed in small utility rooms, wardrobes, cupboards and cabinets to help combat the build-up of mould and condensation in poorly-ventilated areas. Unlike dehumidifiers, they do not use electricity. Typically, they are filled with absorbent beads. Moisture is absorbed from the air and collects in a small chamber. Most moisture absorbers are not reusable, so will need to be replaced once the water chamber is full.

If damp or condensation in your home is more widespread, then a dehumidifier is a good investment. Dehumidifiers are electric appliances that can be moved around the house to help remove excess moisture from the air. They draw air in through a vent, which is then passed through a filtering system. Water vapour from the air condenses into water droplets, which collect in a removable compartment. The air is then recirculated around the room. Less moisture in the air will result in less condensation on walls and windows, helping to alleviate damp and mould.

What is an air purifier?

Air purifiers help to remove allergy-causing dust, pollen and pollution from our homes. They work in a similar way to dehumidifiers, drawing air inside them through a vent. The air is then passed through several layers of filtering material (usually paper or fibreglass), where dust, pollen and pollution particles are trapped. Clean air is then recirculated around the room.
