Having an air filter in your home is essential for keeping the air clean and healthy. An air filter is a screen that fits in the air conditioning system of a home to clean the air as it circulates. It is an aftermarket product with a lifespan that typically ranges from 1 to 6 months for disposable filters and up to five years for washable filters. To find the existing filter, look for a slot next to the boiler or air controller, or check the return air ducts in several rooms of the house. Indoor air can be up to five times more polluted than outdoor air, so having an air filter is essential for keeping your home's air clean.
Exhaust filters are installed in ventilation systems to filter air from an enclosed space before it is released to the environment. Water filtration systems are also used to remove solid particles from liquids. The most effective ways to improve indoor air quality are to reduce or eliminate sources of pollutants and to ventilate with clean outdoor air. The dust holding capacity of an air filter is the average weight of dust that it can retain when gradually charged with synthetic dust under specified test conditions. Fiberglass air filters provide better air flow in HVAC units and are suitable for capturing only large particles.
Carbon air filters are often used in air purifiers, extractor hoods, bathroom fans, and microwaves. Air filters work by sucking dirty air from the environment so that it passes through a filter medium with fine openings. This removes particulates and other pollutants from the air. Some filter brands and retailers use alternative scales, such as Home Depot's Air Filter Performance Rating System (FPR) or the MPR (on 3M Filtrete air filters).It is important to check with a local trusted HVAC service provider to see if an air purification system is right for you. Air filters play a critical role in keeping your home's air clean and healthy, so make sure you choose one that meets your needs.
