What is a dehumidifier?

Dehumidifiers are simple appliances that essentially remove excessive moisture and humidity in the air.

Each unit is comprised of the same basic components:

  • A fan compressor that can pull in air as well as distribute a cooling agent over the units coils
  • Cooling coils to cool the air, thereby removing moisture
  • A heater to dry the air returning to your home
  • Some type of reservoir – usually a plastic bucket – to collect moisture pulled from the air

 

What is humidity?

You may not be able to accurately explain it, but chances are you’ve certainly felt excessive humidity at some point in your life.  Humidity guage

When humidity levels are high, the air feels heavy, and it almost feels like you can swim through it if you wanted to.

In areas of high temperatures with high humidity levels, it can feel like you’re wearing a jumper even if you’re not even wearing a shirt.  This heavy and soggy feeling is due to the high level of moisture currently in the air – or the high level of humidity.

The air can hold a fixed amount of water vapor depending on its temperature.  The ratio of actual water vapor in the air compared to the amount it can hold is called relative humidity.  Relative humidity is often what you mean when talking about the level of humidity in the air.  Most people don’t really care about the reason for heightened humidity levels, but are more concerned with its effects.

Excessive humidity does more than just make you feel uncomfortable and make your hair frizzy.  It can also cause the following:

  • Makes you feel sick to your stomach, especially when combined with high temperatures
  • Disrupts your body’s ability to cool itself, which can lead to various health problems, even heat stroke
  • Triggers asthma and allergy symptoms
  • Makes rooms feel stuffy and overcrowded regardless of how many people are actually in them
  • Places can start to smell musty
  • Can affect the structural integrity of your home, and can lead to an increase in mould and dust mites
  • Attracts unwanted pests, including various bugs and centipedes

 

Dehumidifiers are the perfect solution if you’re suffering from unwanted or excessive humidity in your home or office.

 

Do I really need a dehumidifier for home?

Prospective customers come to us every day asking this question – do we really need another appliance operating in our home using more electricity?

Generally they have one or several symptoms such as mould, condensation, water running down their windows (condensation), dampness, musty odours, family members suffering recurring colds or headaches.

First, make yourself a checklist!

  • Are you able to regularly open windows and doors to allow plenty of air flow?
  • Do you open blinds and curtains to let in as much light and sunshine as possible?
  • Do you have leaks in the roof or walls?
  • Is there a drainage problem that needs addressing?

 

If your answer is “Yes, I am ventilating my home correctly and have no water ingress issues but I’m still having mould and/or condensation problems” – then a dehumidifier should be your next investment. 

There is no easier or more effective way of controlling the humidity levels in your home.  It is humidity levels of 70% and over that are causing the symptoms above and a correctly-sized dehumidifier will assist in resolving these issues.

What kind of dehumidifier for home do I need?

With dehumidifiers, size does matter.  With lot’s to choose from, this is what we mean by choosing the correctly- sized unit.

Select a dehumidifier with poor moisture extraction and you will probably need two, three or even more.

Choose the correct size for your needs, and quite often one is adequate.

Buying a dehumidifier is no different than any other expensive item, you need to do a little homework and seek out reputable resellers that know about different extraction rates, have some history with these products and have some industry knowledge.

Moisture Cure has prided themselves on finding solutions for Australian homes and businesses for nearly 14 years.  

We have a large variety in stock; in-house technician, free delivery to the majority of Australia and a 5 year warranty on our Fral 19 and 24 dehumidifiers.

Call us and we will assist you with choosing the right capacity dehumidifier for your needs.

 

How much water does a dehumidifier extract per day?

You will notice that a dehumidifier is described in terms of litres.  This simply means that a 20 litre dehumidifier has the capacity to extract 20 litres of moisture per 24 hour period when conditions are optimal, i.e. 80% humidity and 30°C.

There will be a higher extraction rate when the dehumidifier is first installed while the machine extracts moisture accumulated in carpets, timber furniture, blinds, bedding etc.  Naturally, it will also be high during wet weather.

In other words the amount extracted depends on how much moisture is around.  It is possible that you may collect more than your next door neighbour on any one day.  This is dependent on factors such as the design of your house, the number of people, the number of utilities being used (cooking, showers, dryers, etc.) and the proximity to lakes, forests and ocean.

How much does a dehumidifier cost to buy?

Dehumidifiers will cost anywhere from between a couple of hundred dollars to a couple of thousand dollars.

As you begin to research machines available, you will discover for a decent quality unit with a known pedigree, a history of reliability and good extraction, you will expect to pay between $400 and $800 plus.  For this price you will have an excellent dehumidifier that will serve you well for many years.

Also make sure the company you are considering buying your new dehumidifier from also has the necessary spare parts in case repairs are needed.  Ask about the manufacturer’s warranty.   Some offer as little as 1 year. 

 

How much does a dehumidifier cost to run?

The real cost of running a dehumidifier has many variables. Of course the initial cost depends on the wattage of each appliance (kilowatt hours) and the electricity tariff in your area.Dollar sign

Our home dehumidifiers range from 180 watts to 500 watts relative to their size/capacity. This equates to a consumption cost of between $0.06 and $0.16 per hour.

These are important factors in choosing the best size dehumidifier. If you purchase a dehumidifier that is too small for the area you are trying to dehumidify, the machine will be working overtime. Whatever you save on the initial purchase cost will soon be negated by its running cost.

Similarly, if you are frightened off using the dehumidifier because of the potential running costs, then you will not be achieving the desired result and your expense will be wasted.

 

How does a dehumidifier work?

While some units have different features and effects, all dehumidifiers work in the same basic manner.  In short, they pull moisture from the air in your room, lowering humidity levels and making your home safer and more pleasant to be in.

The process works as follows:

  • A fan in the unit pulls in air from the surrounding area, which typically has high moisture levels
  • When air passes through the dehumidifier, it touches the cooling coils, which in turn pull moisture from the air by lowering the temperature
  • This de-moisturized air is then heated, which then redistributes back into the room – this time without all the moisture
  • The unit collects the moisture it pulls from the air in a reservoir

 

Many models come equipped with a humidistat, which can detect the level of humidity in the room.  This allows you to program the dehumidifier to run until the air hits a certain moisture level and then automatically shuts off.  The only other thing to worry about is removing water from the reservoir.
