You can choose from a couple of major types of air filters for your HVAC system.
How do you know if electrostatic filters are the right choice for you? Electrostatic filters might be the right choice for you if you want to save money, time, and hassle on your HVAC system’s air filtration but don’t mind paying a slightly higher upfront cost.
But, if you suffer from allergies or asthma, a HEPA filter is recommended. Electrostatic air filters, also known as washable filters or reusable filters, are located on furnaces and typically replace pleated filters. The main purpose of any filter is to clean the dirty, outside air that is being forced into your home. Electrostatic air filters separate themselves from pleated filters by using electricity to trap dust, pollen, and other airborne particles before they enter your home. Just because you hear that these filters go in your furnace doesn’t mean you don’t need them in Arizona. While the dirty air enters, the filter creates electricity. Ionizers then purify the air. Ionizers emit charged ions, which attract dirt particles and add additional charges to them. Electrostatically charged particles drive dirt particles toward the collector, trapping them. After the carbon filter removes the remaining impurities, your home will breathe in clean, fresh air. Electrostatic air filters are cost-effective, save time and hassle, and provide good air filtration. They need to be removed and cleaned monthly to remain effective. Air flow can be negatively affected if they aren’t cleaned regularly. A dirty filter allows more dirt into the system and into your home.
