Buying a dehumidifier can be a hassle-free process once you learn exactly what to search for.
First of all consider why you would like to purchase a dehumidifier.
Do you need to purchase a dehumidifier because you would like to eradicate condensation and mould, could it be because you would like to lower the probabilities of experiencing airborne allergies or possibly you just desire cleaner and healthier air.
Unless you would prefer to keep condensation from the car windows, we advise that you buy a complete size electric dehumidifier which is produced by a recommended dehumidifier brand such as for example Ebac, EcoAir, Inventor and Meaco etc.
1. Desiccant or Compressor Dehumidifier
Your first choice ought to be to make a decision between a desiccant or compressor dehumidifier.
Compressor dehumidifiers are better in warmer environments such as in homes that have been warmed up by radiators.
As a result of how they are manufactured, compressor dehumidifiers are inefficient in cooler environments and tend to be louder and heavier than desiccant models.
Desiccant dehumidifiers have an excellent extraction rate provided that the temperature range is above freezing. Consequently, desiccant dehumidifiers are perfect for outdoor use for example, innurseries, boats, garages, sheds, mobile homes, etc
2. Actual vs Stated Extraction Rates
When buying either kind of dehumidifier, you will get a variance somewhere between the actual and stated extraction rates.
Compressor type dehumidifiers are usually tested in temperatures of 31°C and 82% relative humidity and their unique stated extraction rate denotes this test weather.
The above test climate is actually different to the UK winter season which is when a lot of people make use of dehumidifiers consequently, actual extraction will become much less than the stated extraction rate.
A good guideline is to half the stated extraction and subtract an additional 16%. Therefore a compressor dehumidifier that has a stated 21 litre extraction rate will probably only extract around 8.6 litres each day through the UK winter.
Desiccant dehumidifiers fare considerably better as their standard test climates are less than those of compressor dehumidifier test climates.
Test environments for desiccant systems appear to vary a lot more than the ones of compressor dehumidifiers but a basic guideline is to deduct 21% from the stated extraction rate to obtain the actual rate. Therefore desiccant dehumidifiers that have stated 9 liter extraction rates will most likely extract 6.6 liters of moisture each day.
Note, remember these numbers are approximate, seeing there are a lot of variables to take into consideration.
3. Dehumidifier Size
Unless you are searching for a wardrobe or car dehumidifier, we’d recommend sticking with full model electric dehumidifiers.
For a small to medium area, you might like to look for a stated 6.4 liter desiccant dehumidifier or a stated 11 liter compressor dehumidifier.
For relatively medium to good large areas, then you might look at bigger compressor dehumidifiers that have 17 liter extraction rates or desiccant dehumidifiers that have 8.4 liter extraction rates.
4. Running Costs and Energy Saving Technology
Dehumidifier running costs are less than a lot of people expect with many dehumidifiers costing around 3p each hour to run within their low fan speeds.
When using Laundry Setting to dry laundry inside then your cost could rise to around 9p – 10p each hour based upon the dehumidifier model and brand as well as your electric power rate.
Many dehumidifiers burn up around 200 watts at the reduced fan setting and around 655 watts on 100 % power.
Top quality dehumidifiers boast of energy-saving technology by which the dehumidifiers switch settings automatically based on the humidity air levels. In this manner, your dehumidifier is working at its most effective setting all the time helping you save considerable operating costs.
5. Operating Volume
One of the primary dehumidifier issues is operating volume.
Compressor dehumidifiers are usually louder than desiccant versions.
Operating volume level for compressor dehumidifiers is normally somewhere between 43 db(A) and 49 db(A) (based on model and brand of course of action. Desiccant dehumidifiers seem to use between 39 db(A) and 45 db(A).
6. Number of Fan Speeds
Make sure to check just how many fan speeds your brand-new dehumidifier has. The extra fan speeds your dehumidifier gets the better extraction control you enjoy.
