Best Budget Dehumidifier Under £100 – Pro Breeze 1500ml

The Pro Breeze 1500ml is the 500ml model’s big brother. We really like this model because it offers much better performance than the smaller version. This model has both the largest extraction capacity, 500ml/day and water tank 1500ml available in any mini dehumidifier. The remarkable thing about the Pro Breeze 1500ml is that it only consumes 40 watts of electricity. It is hard to find the same performance in dehumidifiers that only consume 40 watts.

The Inventor Fresh 12L comes in at a little bit over £100 but is a great buy. It offers amazing value and has a 12L water extraction rate and a 2L water tank. The model offers some of the best performance metrics for the price paid. The Inventor Fresh 12L is perfect for more widespread damp issues in homes.

Other features are included like automatic restart, time, and SILENT MODE. We love the addition of silent mode because it makes it easy to run the dehumidifier in a bedroom or living room. Sometimes dehumidifiers can be quite noisy but the addition of silent mode gets rid of this problem. Out of the Inventor 12l and Ansio 12l, we prefer the Ansio. This is because the Ansio includes a 2-year warranty and has a bigger water tank. The exception though is if you would like the silent mode, then you should get the Ansio 12l instead. If you are interested in the quietest dehumidifier, you should read our article on it.

What to Look for in a Cheap Dehumidifier

If you are wondering what to look for in a cheap dehumidifier then we have prepared a handy list for you. We have included the features that we think are most important in finding a good cheap dehumidifier.

Water Extraction Rate

Probably the most important feature of a budget dehumidifier is the extraction rate. Obviously the higher the extraction rate, the more water it can extract. It is worth noting that manufacturers list extraction rates that are possible at 30ºC  and 80% relative humidity. In real life, they will not extract as much water as the manufacturer says. Despite this, a higher stated extraction rate still means more water will be extracted. 

Water Tank Size

Water tank size is an important feature. The main implication of water tank size is how often you will need to empty the dehumidifier. Smaller tanks will need emptying more often than larger tanks. Some models offer continuous drainage options which means you don’t need to empty the tank. 

Electricity Usage

This is one of the most important aspects of a dehumidifier. We have covered energy-efficient dehumidifiers in detail here. The most important thing to note is that higher energy consumption equals a higher energy bill. Always check the wattage of a dehumidifier before you buy it. Cheaper dehumidifiers usually consume more electricity than their more expensive counterparts. 


Dehumidifiers produce noise, sometimes more than you might expect. Most of those we have reviewed here will be very quiet but it is always worth checking the noise level. We have covered the quietest dehumidifiers in great detail here. The feature will matter more or less depending on where you want to use the dehumidifier. 


This can be an important feature if you intend to move the dehumidifier around a lot. Most of the dehumidifiers we have reviewed here are lightweight. Still, if you intend to move the product around a lot, please check the weight in the product description. Vulnerable users may have a harder time moving around a 10kg dehumidifier than healthy individuals. 


This will matter to some people more than others. If you don’t care at all about style then more power to you. If you have just renovated a room and want to make sure you have something that fits in, then you might value style a bit more.
