Your Buying Guide To Dehumidifiers

The right portable dehumidifier can improve your health and prevent moisture damage from causing expensive repairs. Our guide includes all the essential advice you need to find the perfect mini dehumidifier for your home, caravan or office!

What To Consider Buying A Mini Dehumidifier


Make sure that the size and weight is portable and does not take up too much space. This is important if you need to place it on your office desk or in a caravan where space already comes at a premium.

Daily moisture removal rate

Another thing to take into consideration is removal rate. The better economical dehumidifiers will usually remove between 200ml and 500ml of water from the air every 24 hours. The amount of moisture removed will however, depend on relative humidity and prevailing temperatures.

Noise output

Small dehumidifiers are usually well designed for homes and rooms such as the bathroom, bedroom or even office as well. Our advice – you’ll want a unit with quiet operation.

Power consumption

Small dehumidifiers usually operate on a 12 or 9 volt power source. This however isn’t really important. The rating you should really be looking at is the wattage rating. A higher wattage rating means you’ll end up paying higher electricity bills.


Q. How do small dehumidifiers work?

A. Small dehumidifier machines work by pulling air through a special filter and cooled coils. Water condenses on the coils and then drips into a tank.

Q. Where is the best place to put a dehumidifier in a room?

A. The best position to put a dehumidifier in a room is the centre or some distance (preferably 6-12 inches) away from back walls and furniture. This will let the dehumidifier get good airflow around it.

Q. Should I put a dehumidifier in my crawl space?

A. You should put a dehumidifier in your crawl space to protect your home from moisture-induced wood rot and to ensure a comfortable living space for your family.

Q. How do I know if I need a dehumidifier?

A. You know you need a dehumidifier if:

  1. Moist stains are found on walls or ceiling
  2. Condensation covers your windows
  3. Mould is visible
  4. There are musty odours.

Q. Is a dehumidifier good to dry clothes?

A. A dehumidifier is good for drying clothes because it draws wetness from clothes and can help them dry quicker.

Q. Will a dehumidifier in the basement help the whole house?

A. A dehumidifier in the basement will help the whole house because the humidity is mostly transferred from your basement’s walls and ceiling.
