Functionality – Dehumidifier. A dehumidifier will have many more features such as a humidistat and timer. The dehumidifier will also assist in drying towels whereas the extractor fan won’t. Extractor fans generally only run whilst you are in the bathroom. This leaves your bathroom vulnerable to dampness when you leave the room after a shower. The Verdict – It Depends. Water tank capacity is also reduced compared to the ProBreeze's super generous 1.5L tank, with the Silentnight model only able to hold 0.6L of water – which means you'll be emptying the tank a lot more frequently.

If you are worried about high running costs, choose the Meaco,” says Chris Wood, another expert from Aircon Centre. “It has a control system that can reduce your energy consumption by up to 80 percent compared to other dehumidifiers.”First up, it's worth making clear that this small dehumidifier has a low extraction rate compared to many others on our list. The ProBreeze 1500ml Mini Dehumidifier can extract just 0.5L of moisture from the air per day. For comparison, the lowest extraction rate offered within the MeacoDry Arete One range is 10L of moisture extraction per day.

It’s the setting with the highest ventilation speed and dehumidifying capacity. In my testing, I found it to really work. I don’t struggle too badly with mould in winter but I do find it difficult to dry clothes (I’m a little too stoic about not switching on the heating). With this DeLonghi dehumidifier sat next to my standard, non-heated clothes airer, my washing dried within a few hours, including a pair of jeans and a hoodie. This is another important aspect to consider when choosing a dehumidifier for your cannabis grow room. Dehumidifiers with large reservoirs obviously need to be emptied less frequently, but they also typically take up more space and are more expensive. The latest model in Meaco’s dehumidifier range is a compact version of the superb Arete One, dropping the extraction rate down to ten litres per day, but reducing the size of the unit to less than 50cm high. Not only is the Arete One 10L physically unobtrusive, but it’s also impressively quiet. While we measured noise levels of around 42dB with the fans running at full tilt, these rapidly decreased to well below 40dB, which is about as close as dehumidifiers get to silent. In its night mode, the Arete One 10L can go as low as 35dB. If you’re always keeping up with your house, congratulations. You can probably use your dehumidified water to water your plants with minimal concern, especially true if they’re outside plants.The transparent water tank means I can keep tabs on when to empty it although it rarely needs emptying more than once a day. The dehumidifier also automatically switches off when the water tank reaches its maximum capacity of 2.1l. If you’d like to try this method, flush the toilet and immediately refill it with water from the dehumidifier. If your dehumidifier makes enough water, you could save up to six gallons of water per day! Use It to Wash Your Car When the dehumidifier is in operation, a green light tells you it's on, this light turns orange when the tank is full and the dehumidifier will automatically shut off when tank capacity is reached.
