Suitable for a single person living in a small flat, looking for a lightweight and portable machine to tackle a mild damp problem. You simply take the humidity reading before you make your DIY moisture absorber and again once the moisture absorber has been functional for some time. This could come in handy if you want to turn your dehumidifier on or off or adjust the settings, such as fan speed, while you're in another room or even out of the house. There are two main types of dehumidifier to choose from – refrigerant (also known as compressor) and desiccant.

Moisture absorbers (also known as damp traps) contain crystals that absorb moisture and dissolve as they make contact with air.If available, make use of timer or automatic shut-off features so the dehumidifier isn’t running continuously while you’re out of the house or asleep. The cure of course is to bring the humidity level down and keep it down but how do you do that without spending a fortune on an electrical dehumidifier? Because desiccant dehumidifiers can be more powerful than refrigerant models, they can cover a larger area than a refrigerant of the same claimed capacity. This allows you to specify a relative humidity (RH) that you want the dehumidifier to try to create in the room. Here’s the problem: the dangers of calcium chloride desiccants to human health are extreme and can even lead to burns in the mouth and throat.

My refrigerant-cycle dehumidifier machine produces more than a liter per day (in the summer), so if a desiccant-based bag of “salt” was equally effective, I’d have to put up a new bag every day. We've highlighted the best dehumidifiers we've tested, while our expert guide explains your options and takes a closer look at whether you need a refrigerant (compressor) or desiccant model. You should also bear in mind that manufacturer claims about water extraction rate are often based on conditions you're unlikely to experience in your home.So moisture absorbers can help with small day-to-day damp issues, but shouldn’t be relied upon for any serious damp-busting. If you’re purchasing from a private seller, be aware that, unlike retailers, they are not obliged to proactively highlight any faults. The desiccant is regenerated by an internal heater, and the moisture drips into the water condenser. Some “do-it-yourself” and other powered dehumidifiers rely on fans to circulate air over calcium chloride salts.

Empty the water tank after every use, if you can, and definitely before packing it away for storage. If you're going to be using it in an unheated room, or in a range of conditions, go with a desiccant. As they're not reliant on the temperature in the room being warm, desiccant dehumidifiers work more effectively than refrigerant dehumidifiers in colder temperatures of 15°C or less.A humidistat monitors moisture levels in the air and adjusts the dehumidifier to maintain the humidity level you’ve selected. Mini dehumidifiers can be plugged into the wall and can be placed nearly anywhere without the health risks associated with calcium chloride.
