Do All Houses Need Air Filters?

Larger homes often have more than one HVAC system, each of which will typically have at least one air filter. It is important to check every possible location to make sure all air filters are accounted for. One type that can be difficult to find in stores is the whole house air filter, which is different from the more common one-inch filters. It is important to note that an air purifier is an addition to your HVAC system, not part of it.

Air filters are not optional and are necessary for cleaning the air and ensuring good air quality as your unit circulates between indoor and outdoor air. Generally, it is recommended to have an air filter on each return grille, as long as the correct size and thickness is chosen. Filters will improve the air quality in your home and protect HVAC equipment from dust, pollen, pet dander, and hair. When air enters the system, it passes through a filter that captures a large amount of particles in the air.

Factors such as the type of filter you have, the size of the house, the quality of the air, the number of pets in the house, how often you use your unit, and if you or someone in your family has allergies or certain medical conditions all play a role in determining how effective your filter is. If you are looking for better indoor air quality, you may need an air cleaner or an air purifier in Houston, TX. Professionals can make sure you have the right type of air purifier combined with the filters. Clogged filters require the system to put more effort into maintaining standard air circulation in your home.

A fiberglass filter is the cheapest option, pleated filters better trap particles in the air, while HEPA filters are capable of filtering 99.97% of all particles. An air conditioning system has a filter to prevent dirt and debris from entering the unit and entering the indoor environment. This filter is located at the point where the return air duct connects to the HVAC cabinet on the blower. It is important to understand what an air filter does and why it is there because a frozen evaporator coil can prevent an air conditioning unit from pulling back the air conditioner, resulting in a warm home or office even if you change the thermostat to its lowest setting.
