Worried about condensation, musty odours, and excess moisture in your home? SmartAir Dehumidifer is the dehumidifier that removes up to 20L of damp, mould and moisture from the air daily, is energy-efficient and comes packed with features. It’ll even help you dry your clothes faster! 

  • Removes up to 20L of moisture per day: Dehumidifier’s powerful, rapid extraction lowers humidity levels, helping prevent mould, mildew, and condensation in your home. 
  • Prevents Mould and Mildew: removing moisture from the air in your home helps you stop mould and mildew from taking hold in damp areas.
  • Costs just 11p an hour to run! 
  • Dry your laundry quicker, easier and cheaper: Dehumidifier’s laundry mode runs continuously at a high speed to remove moisture from the air quickly, so your clothes will dry faster – and it costs less to run than a tumble dryer!
    • Features 5 modes:
      • Normal Mode is simple and cost-effective. Select a target humidity and Dehumidifier will run until the room reaches your desired humidity, then it shuts off on its own.
      • Continuous Mode is perfect for rooms with a lot of excess moisture. Dehumidifier will run continually, constantly removing moisture from the air with a fixed low-speed fan.
      • Strong Mode is ideal for rapid dehumidifying – it removes moisture from the air until your room reaches 30% humidity with a fixed high-speed fan.  
      • Laundry Mode is the money-saving alternative to tumble drying! A fixed high-speed fan rapidly pulls the moisture in from your room helping your clothes dry faster – it also prevents rooms from retaining the moisture emitted from the laundry!
      • Sleep Mode runs alongside any of the other four modes, all lights on your Dehumidifier will turn off so you’ll get a restful sleep while the bedroom air maintains a perfectly balanced humidity level.
  • Take the chill out of any room: make any room feel warmer in minutes by removing the excess humidity.
  • Protects your home, furniture and belongings: removing and preventing excess moisture in your home shields your furniture, electronics, and clothing from damage. 
  • Creates healthier indoor air quality: dehumidifying the air in your home prevents mould spores from growing – breathe easy with Dehumidifier!  
  • Eliminates Musty Odors: reduce the humidity levels that cause stale, unpleasant smells, leaving your home smelling fresh! 
  • Intelligent humidity sensor: you can trust SmartAir. Dehumidifier monitors room humidity and updates the easy-read LED display so you can rest easy knowing your home is protected from excess moisture.
  • Large 5.5L water tank: perfect for larger spaces and extended use without frequent emptying. 
  • Optional continuous drainage hose: includes a 1m hose for uninterrupted operation, ideal for long-term use. 
  • 24-Hour delay timer: program the dehumidifier to start or stop exactly when you need it, you’re in complete control. 
  • Sleep mode: disables display lights while maintaining full functionality for peaceful, nighttime operation. 
  • Portable design: the compact, space-saving build features four castor wheels and two carry handles for easy movement between rooms. Take Dehumidifier where you need it!

Rated 5 out of 5 by KJ H from SmartAir FDD20-5294ZFR5 I love this piece of equipment it’s absolutely great and I can’t believe that I haven’t bought one before this. Not only does it look good with its slim build, but it’s very efficient and runs quietly, the laundry mode really makes a difference when you’re using it to help dry clothing indoors, the operation of the unit is easy as is emptying the water tank. It gets rid of condensation and cleans the air brilliantly. Well worth the money. I would highly recommend this product.

Rated 5 out of 5 by jen123 from I wish it wasn't so good! I've bought several dehumidifiers over the years. From really cheap disposable ones to £100 versions from AZ. They all "sort of" helped but never solved our condensation problem. My husband seen an advert for this Smart Air at silly o'clock on a Saturday morning and convinced me to try it for the laundry function. It arrived and I hate to say how good it is. The amount of water it collected in 6 hours was MORE than the £100 versions did in 4 days! I am not exaggerating when I say that! Brought all rooms down to 30/40% humidity within 3-4 hours and they started at 60-70%. It is frightening how much water it collects! I actually bought a second one for the other side of the house 2 days after receiving the first one. We use these with a smart energy monitor plug and we find 1hr costs around 7/8p to run it on laundry mode (23p unit rate) so while it is expensive compared the £100 version (2p an hour) it only needs to be on for a couple of hours a day in our house. We have also found that when used in the bedrooms, it actually heats up the room too. Adding around 3-4°C while removing humidity - I cant fault it. Although it now means my husband is smug that he suggested such a great purchase.
