Product Overview

Premiair 20L-Day Compressor Dehumidifier - EH1934

This Prem-I-Air compressor dehumidifier extracts up to 20L of moisture from the air per day and is perfect for home or office use. The unit features an LCD display and control panel that are easy to read and use. By reducing the amount of moisture in the air, is created the perfect humidity level for a comfortable environment. Conveniently, the unit will automatically shut down if the water tank becomes full, or alternatively can be used in continuous mode, whereby the hose will drain the water that is captured for longer dehumidifying periods with minimal monitoring. It can be effective for areas with mould/mildew build up, as condensation is removed from the air. Operating the unit is simple, plug it in, set the humidity level and timers, or locks if necessary. 

With a maximum of 45dbA noise level, the unit won't disrupt you from work or other activities and will quietly operate in the background. The dehumidifier can also aid in laundry drying.

Frequently Asked Questions

What size dehumidifier do I need?

This will depend on the space, condition, and application. Smaller rooms require an 8 – 10L dehumidifier, whereas a whole house would require a 25-30L one. Specific damp problems or laundry drying may also increase the size of the dehumidifier. We go into more detail in the article What Size Dehumidifier do I Need.

What is a dehumidifier size?

When we talk about dehumidifier’s size, we mean the extraction rate. This is the amount of water in litres it can dehumidify within 24 hours. It’s important to note that we don’t mean the tank capacity. Dehumidifier tanks tend to be between 2-6L and would need emptying during the day. Most dehumidifiers can provide continuous drainage through a hose into a drain.

Can you use a dehumidifier as a clothes dryer?

Yes, many units have a laundry mode, which is specifically used for drying clothes. Using a dehumidifier to dry your laundry can save you a lot of money in the long run. Read our Dehumidifier vs Tumble Dryer article to see how getting a dehumidifier can save you up to £150 a year! Or shop all dehumidifiers with the laundry mode here.

Can a dehumidifier purify the air?

Yes, some dehumidifiers can be used as an air purifier. We have a range of dehumidifier with HEPA and dust filters. Always make sure to check the product description or user manual to see which modes your dehumidifier has.

What is relative humidity?

Relative humidity is a percentage of water vapor in the air compared to the maximum it can hold. So for example, if the relative humidity is 50%, that means currently the air contains half the amount of water vapor it can hold. The higher the humidity is, the warmer you’ll feel and your home will be more prone to mould. The lower the humidity is, the dryer the air will be.

What is the ideal humidity for my home?

For the UK, it is recommended to keep our home’s humidity between 50% - 30%. Any lower the air will be excessively dry causing dry skin, throat, and nose. Any higher, the air will be excessively moist which can cause damp and mould damage.

My dehumidifier unit is blowing out warm air, is this normal?

Yes, your dehumidifier can be blowing out warm air. This is due to the process of dehumidifying and is completely normal.

How much does a dehumidifier cost to run?

This is going to differ unit to unit. For example this Devola 12l compressor dehumidifier will cost you around 5p per hour, or this Meaco 25l dehumidifier around 7p per hour (these prices are based on the April 2024 price cap).

I’m still unsure on which dehumidifier to get, can you help me decide?
