If the level of humidity in your home is out of control and you feel you need dehumidification in more than three rooms you should consider purchasing a whole house dehumidifier.
You should also consider buying one if the allergy sufferer in your home has little control over their symptoms.
A whole house dehumidifier, along with decreasing the level of humidity in your home, can decrease the amount of allergens as well. These allergens like to live in a warm environment with a lot of moisture.
This moisture clings to everything, especially your carpet and upholstery. Dust mites love carpet and upholstery and they are probably everywhere because of the carpet and upholstery you have in your home. Housecleaning is a chore that no one likes to do but if you clean frequently you should be able to help keep the allergens under control.
Now, we can't live without our furniture but we can live with hardwood floors or laminate flooring and area rugs. Keeping these things clean can also reduce the amount of dust mites you find in your home. You can't see them but they are there.
Too much humidity in your home can cause you to feel sticky and uncomfortable. It also can cling to your walls and woodwork and cause mold and mildew to form. This happens frequently in your bathroom and should be dealt with immediately. You can kill mold an mildew with a mild bleach solution in a spray bottle.
When choosing a dehumidifier for your home you should first, measure the rooms that the dehumidifier will be handling and make sure that the unit you buy is big enough and powerful enough to control the humidity throughout your house.
The correct square footage matters. That is how the units are sold, by how much square footage they can handle. So, be sure to measure correctly and then multiply the length of the room by the width of the room and add all the room measurements together then buy the dehumidifier that has a range and that number is at the top of that range.
Do not be confused by all of the smaller portable units. They are only good for single rooms or areas and can be rolled from one room to the other with little effort. A dehumidifier that can control the humidity in your entire house is a bigger unit that is permanently situated near your ductwork system connected to your furnace and air conditioner.
The unit is connected directly into the ductwork so the vents in your house help disperse the drier air to all the rooms in your house. If the dehumidifier runs a while and you notice that things are getting a,little too dry then just reset the dehumidifier to a higher humidity setting.
You will not have to worry about carrying and dumping the water from your whole house dehumidifier either. It will have a drain running from it to the floor drain in the basement, or depending on where it is situated in your basement it could possibly drain to the outside of the house.
