Do whole house dehumidifiers work?

Yes. If you are experiencing high humidity levels in your home, a dehumidifier can really work for you. A dehumidifier will reduce the moisture in the air around to prevent side effects of high humidity indoors and other related effects like condensation. 

What should you look out for when buying a whole house dehumidifier?

Area coverage. The dehumidifier’s area coverage plays a vital role when buying one. This will help you buy a dehumidifier that has the strength to remove moisture in the whole house. If you want a dehumidifier that is ducted to the HVAC system, you need to know how big your house is. With HVAC the device will be able to cover the whole house. However, there are exceptions. For instance, small town houses or apartments cannot duct a dehumidifier. This means you need a large dehumidifier. On average a whole house dehumidifier should be able to cover at least 3500 square feet and more. 

Drain options. Dehumidifiers have water tanks, which you can personally drain out. However, for a whole house dehumidifier, it would be a hard task to personally drain it. In this case, we recommend you look out for a dehumidifier that has a continuous drain option.

Extraction capacity. Dehumidifiers are commonly differentiated by their water extraction per day. You should also note that the capacity of the dehumidifier can be affected by area size and moisture levels. In case the space around your house is less than 2000 square feet, you may consider having a unit with capacity of about 20-30 pints per day. However, if the same space is saturated with relative humidity ranging from 90-100%, you will need a unit that can remove 30-50 pints per day.

Noise. On average, whole house dehumidifiers produce a noise level of 55 dB due to fan speed and size. A refrigerator produces an average of 50 dB and an air conditioner produces 60 db. This means at minimal fan speed, a whole house dehumidifier should have a sound level that is more or less in the same range or lower. 

How big of a whole house dehumidifier do I need?

You should not stress about the size of the whole house you need. What you have to know first is the size of your house. This will give you a hint on the kind of dehumidifier you have to get. However, on average you need a whole house dehumidifier that can cover up to 3500 square feet and above. 

Is a whole house dehumidifier worth it?

Yes, a dehumidifier is worth it. As a homeowner you would want to make your home comfortable for you and your family. But when there is high humidity in your house, you may not be as comfortable as you would wish. This is because high humidity will always lead to the rust on metals, unpleasing odors, growth of mold and mildew. A dehumidifier will help you avoid these conditions and enjoy your house. Dehumidifiers work by removing high moisture in the air, and reduce humidity levels. 

Where is the best place to put a dehumidifier in your house?

This may vary based on individual preferences and the conditions of the house. However, you can place your dehumidifiers based on factors such as temperature, rooms with the most moist air and how dust prone a room might be.

  • Temperature. You can place your dehumidifier in an area with the least temperature (cold). This is where humidity concentrates more.
  • Floor with most moisture. You can place your dehumidifier either on the floor or room with high moisturized air. This could be the kitchen, bathrooms and downstairs.
  • Amount of dust in a house. You need to find a place with less dust. This is because dust will significantly affect and damage the dehumidifier filter.
