  • Carbon filter

Best Features of the Ebac 3850e Dehumidifier

  • Condensation cure guarantee. Ebac are so confident that the 3850e will cure condensation that they offer a 30-day condensation cure guarantee. If the dehumidifer hasn't helped your condensation problems after 30 days of use, then Ebac will give you a refund. You must call Ebac on 0345 805 0000 first to confirm your condensation cure guarantee refund before you contact us to arrange your return.
  • The most trusted dehumidifier brand in the UK. Ebac have over 50 years of dehumidifier manufacturing expertise. They're the only brand that actually makes dehumidifiers in the UK, specifically for the UK climate. Every component is specially engineered and produced by the brand to be the very best. Their high-quality compressor reduces noise and vibration, and lasts much longer than other brands' compressors. When you buy an Ebac dehumidifier, you can be 100% confident that it will solve your damp and condensation problems. They also have the lowest carbon footprint of any dehumidifier brand sold in the UK, as all other brands are imported from China.
  • Low running costs. Not only do Ebac dehumidifiers remove moisture; they also release heat, which makes them almost energy-neutral. By reducing the moisture in the air, you can turn your thermostat down by 1°C and it will feel the same temperature. Using Smart Control, the 3850e will only cost around £0.45 per day to run.
  • Patented Smart Control. The 3850e has intelligent electronic software which monitors the moisture levels in your home and automatically adjusts its operation according to these levels to prevent damp and condensation. Smart Control is much more more effective at eliminating damp and condensation than a humidistat. It prevents constant manual adjustment, plus it's more energy-efficient and can save about half of your running costs - up to £113 a year. Ebac dehumidifiers are the only dehumidifiers on the market with this technology.
  • Laundry drying setting. The 3850e has a laundry drying mode for drying laundry indoors. Simply hang your wet clothes on a clothes airer, place them in a room along with the dehumidifier and they’ll be dry in no time. A dehumidifier is a much cheaper alternative to a tumble dryer, with no shrinking and a lot less creasing of your garments. It's also great for any clothes that can't be tumble dried.
  • Patented Intelligent Defrost. Due to the often unpredictable climate in the UK, it's not unusual for a dehumidifier to ice up at the rear of the unit. The 3850e has a computer-controlled defrost system which detects this and automatically defrosts itself to maintain maximum efficiency. Ebac dehumidifiers are the only dehumidifiers on the market with this technology.

NEW & Improved Secure Deliveries

PIN code verification at your doorstep

We've improved the security of our deliveries to you with DPD's PIN code verification system. We will be using this service on most orders to ensure your parcel gets to you securely.

You will receive a PIN code via text and/or email which you must recite to the delivery driver on arrival. If someone is receiving the parcel on your behalf, remember to pass on the code to them. The driver can also resend the PIN code to the original contact on arrival if required. This service requires a mobile phone number with your order so please ensure you provide one to take advantage.


- Our deliveries are very easy to track, plus you'll get a handy 1 hour delivery window so you know when to expect your items. You'll receive a tracking number with your 'order dispatched' email.

- Your VAT invoice is always in the box with your goods.

- Your goods are always securely packaged when leaving our warehouse. We strive to ensure your goods reach you in prime condition.

Our main courier is DPD. We use DPD for the vast majority of our deliveries. APC and TNT handle other specific types of deliveries for us. In poor weather conditions our couriers may experience delays that are out of our control, however we will help you in every way possible to track delivery progress.

- Delivery to construction/job sites is possible, but done so at your own risk. Our service can deliver to an address, but we can't guarantee delivery to a specific person or location at the address. For the best outcome, please provide detailed courier instructions and a contact number that we can pass on to the courier.

- Delivery to 'safe place' is not available for most orders, someone must be present to receive your delivery. We do this to ensure our couriers deliver to the right person at the right address, to ensure your goods are not lost or stolen. Particularly as most orders are of high value.
