A Mini Guide To Dehumidifiers And Their Uses

We all want to save a penny whenever we can. One way is by using an electric shower. They only heat the water in use. A bathroom extractor fan can get rid of the steam caused by the electric shower. It will also get rid of the warm air so that you don’t have to switch on your ceiling fan or portable air conditioner.

Another great energy saver is a wireless thermostat. It allows you to easily control your heating and cooling system depending on the temperature changes, and you can also monitor energy consumption.

For small areas like your office or car, a mini dehumidifier will be ideal since it keeps the air fresh and dry without using too much energy. We will show you how to choose the best dehumidifier.

Types Of Dehumidifiers

Dehumidifiers can be classified according to type, how they work and their size. With regard to type classification according to dimensions, you have mini type, medium size and whole house dehumidifiers.

Mini dehumidifiers are small appliances weighing a few kilograms and are designed for use in small rooms. These are the common types of dehumidifiers we cover in our reviews. Medium size dehumidifiers are larger than the minis.

They’re well designed for use in slightly larger rooms. Some of these also act as purifiers and feature air filtration systems. Whole house dehumidifiers are large units which are usually installed outside the house.

They’re connected to networks of ventilation systems which branch out to the different rooms in the house. They usually work by blowing in cool dry air into the rooms and drawing out warm humid air.

Guide of Using Dehumidifiers

If you want to get a dehumidifeir, the important thing is the classification by how the dehumidifier works.

Refrigerant Dehumidifiers

These have a fan which draws warm humid air into the dehumidifier. A refrigeration method like a compressor or thermo-electric cooling cools a metal plate upon which the warm air is driven. The cooling metal plate draws water from the air which is then released into the environment.

Desiccant Dehumidifiers

Desiccant dehumidifiers use a chemical lika silica gel attached to a rotating wheel. As humid air passes through the desiccant, moisture is drawn from it. As the wheel continues to rotate, the moisture within the desiccant dehumidifier is drawn and drained out of the unit by passing the desiccant through warm air. Desiccant dehumidifiers are usually smaller compared to refrigerant types and usually make the best quiet dehumidifier.

Ventilation Dehumidifiers

These make the best home dehumidifiers, they are quiet and inexpensive to operate. They usually operate by heat exchange where dry, cool fresh air is drawn into the house, displacing warm humid air.

What To Consider Buying A Mini Dehumidifier

Small dehumidifiers are designed for use in single spaces like the bathroom or a car. They’re highly portable and easy to operate. If you’re looking for the best compact dehumidifier, here are some considerations to make.

Size

When you want to get a dehumidifier, dimensions might mean two things. First, it means the dimensions of the unit. If you’re limited on space, a smaller dehumidifier is recommended. The second meaning of size is its volume capacity. That is, how much water the collection tank will hold before you need to empty it.

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.

Dehumidifier Frequently Asked Questions

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 you run a dehumidifier in winter?

A. You should run a dehumidifier in winter if the relative humidity level stays above 50% for most of the time. You will likely need to get a dehumidifier for your basement more in winter because it's the coldest part of your house.

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. Much moisture is in the air
  5. Musty odour is perceived

Q. Will a dehumidifier lower my electric bill?

A. A dehumidifier will lower your electricity bill because your home will feel cooler with low levels of moisture from the air. Also, you don't have the need to run your air conditioner often.

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. How long does a dehumidifier last?

A. Generally, dehumidifiers typically last 3-5yrs with constant use and under normal working conditions.

Q. Will a dehumidifier make a room cooler?

A. A dehumidifier will make a mini room cooler not because it produces cool dry air but because it removes humidity from your home and leaves the atmosphere cool and comfortable.

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

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