When it comes to keeping your home’s air clean and healthy, many homeowners assume their HVAC system’s basic air filter is doing all the heavy lifting. While these filters do play an important role in protecting your HVAC equipment from dust and debris, they\u2019re not designed to eliminate many of the particles and contaminants that can affect your health. That\u2019s where whole-house air purifiers and filtration systems come in.<\/p>\n\n\n\n

Every central HVAC system has some form of air filter. These are typically located in the return air duct and are meant to trap larger airborne particles like dust, pet hair, and lint before they reach the HVAC unit\u2019s internal components. Standard filters have a low MERV (Minimum Efficiency Reporting Value) rating and aren\u2019t capable of capturing the smaller pollutants that affect indoor air quality, like bacteria, smoke, and allergens.<\/p>\n\n\n\n

Even upgraded filters with higher MERV ratings may struggle to remove microscopic particles or odors\u2014and installing filters that are too restrictive can even reduce airflow and put unnecessary strain on your HVAC system if not properly matched to your equipment.<\/p>\n\n\n\n

Air Purifiers: Going Beyond Basic Filtration<\/h3>\n\n\n\n

Air purifiers are more advanced systems designed to remove a wider range of airborne contaminants. Whole-house air purifiers are professionally installed as part of your HVAC system and use additional technology to clean the air. This may include:<\/p>\n\n\n\n
