Air Purifiers Versus Dehumidifiers in Richmond, TX

Both air purifiers and dehumidifiers can improve the indoor air quality in your home. However, how they go about this is quite different. When deciding between the two, it helps to know what is causing the air quality of your home to be poor.

Air Purifiers

An air purifier has a series of filters made of different materials to remove pollutants from your home’s air. The filters trap pet dander, dust mites, bacteria, pollen and other pollutants to make air cleaner. An air purifier can also remove unpleasant odors. As the filters capture mold spores, an air purifier can prevent mold from growing.

A dehumidifier removes humidity from the air inside your home. This prevents the growth of mold and bacteria, both of which pollute the air. A dehumidifier pulls air into it and removes excess moisture. The moisture is then drained away.

Which One Is Best for My Home?

As you can see, air purifiers and dehumidifiers work differently. Which one is best for your home depends on what problem you are trying to solve. An air purifier removes all sorts of contaminants, while a dehumidifier solves problems caused by excessive humidity.

A dehumidifier prevents bacteria and mold from growing in the first place, as both need excessive humidity to flourish. An air purifier removes these contaminants from the air once they’ve taken root in your home. However, an air purifier will remove many contaminants from the air that aren’t caused by humidity.

If you live in an area that’s excessively humid, a dehumidifier may be the right choice for you. If you have problems not caused by humidity, an air purifier is a great choice.
