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

This is not a straightforward question as not all damp issues are caused by too much moisture in the air.  We at Dry Home are not just sellers of dehumidifiers we are damp experts and will never sell a customer a dehumidifier if it’s not the correct solution for their problem.  Below are some symptoms that might indicate you have an issue but also see our Different Types of Damp Page for more information.

Condensation on windows
Wet stains on walls and ceilings
Mouldy bathroom
Musty smells
Black/dark specks on walls ceilings that grow over time
Persistent flue like symptoms
Allergic reactions
Ongoing allergies

2. Who needs a dehumidifier?

Having humidity levels of 50% or higher in your home isn't just uncomfortable it can also damage your property, and humidity can even make allergies and asthma worse.  See our Health Page to learn more about how excess moisture can be damaging your health.


3. Can I leave my dehumidifier running when I’m not at home?

Our dehumidifiers will turn off automatically when the water tank is full, so you don’t risk a flood.  They also allow you to set the humidity range via a built in humidistat that will again automatically turn the dehumidifier off when it’s not required saving electricity if you’re not around to turn it off when the air is as dry and you want it.


4. What humidity level should I aim for in my home?

You should be aiming for the room's humidity level to be somewhere between 30% and 50%


5. Why should I buy a dehumidifier that has an Air filter?

The air filters in our dehumidifiers do two very important jobs and only dehumidifiers with good easy to clean air filters should be considered. The air filter cleans dust from the incoming damp air to stop it clogging up and possibly damaging or shortening the life of the machine, and the cleaning of the air also means the recirculated air pushed back out in to the room is not only much drier but also cleaner.


6. What Dehumidifier capacity do I need?

According to lab tests run by US consumer organisation Consumer Reports, large capacity dehumidifiers generally work quicker and more efficiently than a smaller unit and will be able to handle a greater range of humidity levels with little or no added noise.  Dry Home offers two different sizes of dehumidifiers to suit the size of your home but we recommend the larger model the DH24.  The DH24 is fitted with a humidistat that only turns the dehumidifier on when the humidity levels are too high so there is no disadvantage of having the larger model.


7. Can you use a dehumidifier to dry clothes?

There are many reasons why your home may have excess moisture and drying cloths in doors is one of those. Just image how much water wet clothes still have in them after they come out of the washing machine. It can be litres for each load. For the clothes to dry that water has to come out of the clothes and in to the air. A normal clothes dryer does this by evaporating the water using heat and blowing that now water ladened air into your home. If that warm humid air touches a cool surface such as a wall the water condenses leading to issues such as mould. A dehumidifier will also dry your clothes but instead of distributing all that water throughout your home it traps the water so it can be poured away or used to water your garden. Also a dehumidifier uses a fraction of the electricity a normal clothes dryer uses to run. See the FAQ “How much does a dehumidifier cost to run?” for more info.


8. What useful features should I look for in a dehumidifier?

Continuous drainage:

If you don’t want to empty the tank regularly, this feature allows you to connect a hose to the dehumidifier and flush collected water directly away to a low-level drain.  All our dehumidifiers can be continuous drained.

In-built or automatic humidistat:

With this, the dehumidifier monitors the moisture in the air, usually so it can turn itself on and off to maintain the humidity level you’ve selected.  Again all Dry Home dehumidifiers come with a built in humidistat.

Timer:

Some models of dehumidifiers have a timer but we feel it’s not particularly useful. As our dehumidifiers are fitted with a humidistat that automatically turns the unit on and off as required we see no advantage of having a timer.  However if a timer is required a power plug timer can be easily purchased from any good hardware store for less than ten dollars.  This simple device plugs in to your wall socket and you can then plug the dehumidifier into the timer. These devises actually have an added advantage over built in timers, as multiple times can be set.

Mobility:

All dehumidifiers are mobile right, well yes but not all dehumidifiers are equally mobile. Dehumidifiers can be heavy awkward boxes so any features that help mobility are essential. Dry Home dehumidifiers come with a large comfortable and easy to use handle at the top of the unit and sits on 4 sturdy multidirectional casters

Cord Storage:

It will depend on your location but typically a dehumidifier is not required all year round in Australia and therefore cord storage helps when storing the dehumidifier.


9. Why shouldn’t I just buy a cheaper dehumidifier from China off ebay?

ebay is great for buying low cost disposable items but you want a dehumidifier that’s going to last.  Dry Home is in contact with customers that are still happily using previous Dry Home models they brought 10 years ago.

But more importantly you need a dehumidifier that has been tested to Australian Standards for safety. Dry Home has commissioned it own onshore testing to make sure the dehumidifiers we supply compile with Australian standards.

Also we are not a faceless online company who will suddenly disappear if you have issues. We are not appliance suppliers we are damp specialist. We will not sell you a dehumidifier if it will not solve your problem. See our Different Types Of Damp Page for more info.

We are an Australian company based in Sydney with over 20 years experience. All dehumidifiers come with a two year warrantee but we expect them to way out last that.  Also if you are in the greater Sydney area we will personally deliver the dehumidifier, unpack it, help you position the unit to best optimise the performance, and if you have an issue we will come back to you and fix or replace the unit.  Yes that's right we come to you. Basically we offer good old customer service.


10. How much does a dehumidifier cost to run?

Dehumidifiers are amazingly cheap to run.  When tested by the leading consumer advocacy group in Australia the Dry Home DH24 dehumidifier and found it to cost just 8.6 cents per hour based on electricity costs of 22c/kWh.  It’s hard to say how long the dehumidifier will have to run as it will depend on the conditions but if you run the unit for 10 hours a day that would be only 86 cent a day.

In comparison a typical air conditioner that could also be used to dry the air will cost you $3.96 for the same amount of running time. So if you need to dry the air for 6 months of the year a dehumidifier would save you almost 600 dollars.
 
A typical clothes dryer will cost 50 cents an hour to run and can typically run for 3 hours per load costing you $1.50, which is almost twice the cost of running the dehumidifier for 10 hours. Plus of course the clothes dryer is making the air moisture levels worst causing you to run a dehumidifier or air conditioner to dry out the air again.


11. How do I clean and kill mould?

This is a great question after all it’s likely you have spotted some or you would not be looking at our website.  Mould and mould spores are amazingly hard to kill and if they are within fabrics it may be almost impossible.  This is why prevention is so much better and cheaper than the cure.  Choice Magazine have done some research in this area and have a great free article that is well worth a read.
