What else might you want to consider when sizing a dehumidifier?
Having studied the guide you will easily be able to see the minimum size needed for your home.
First, you need a “margin for error”. If you work out that a 30-pint unit is just big enough for your needs we recommend that you buy at least a 40-pint unit. The 30-pint model you buy may actually have a capacity of 28 pints, due to errors in testing or simply rounding the capacity up to a “neat” figure. Its performance may deteriorate a little over time. You may have classified your room as one level drier than it is, or you may even have made a mistake when taking the measurements. When sizing a dehumidifier in Singapore it is better to play it safe and choose one a little bigger than you apparently need.
If your intention is to maintain a level of relative humidity much below 50%, say 40 or even 35%, you will need a slightly larger capacity appliance to achieve this. If you select a unit that is “just big enough” it is likely that it will run continuously rather than cycling on and off as it should.
A larger model will run for fewer hours per day to maintain your chosen level of relative humidity than a smaller one. These appliances are noisy and larger models are noisier than smaller units. The noisier one may, however, be less of a nuisance if it can be switched off when the noise is most intrusive, when you have a company or while watching TV for example.
Larger models consume more energy than smaller ones but they remove more water per energy dollar than smaller units so are more efficient. Since energy will almost certainly cost more over the lifetime of your appliance than the unit cost to buy this may make the larger model cheaper overall.
As you can see there are a number of arguments for buying a unit larger than the best available guidance suggests. This is an entirely individual decision but you may wish to take our comments into account when sizing a dehumidifier for your home. To buy portable dehumidifier visit HVAC Website
