The air in your home is up to five times more polluted than the outside air. Impurities such as dirt and dust, pollen and pet dander, mold and bacteria, and smoke and smog build up in your air conditioner and ventilation system, causing allergies, asthma triggers, and other respiratory problems. Remedy these problems by replacing your air conditioner filters and breathe easy.
A good AC filter uses special, densely woven, electrostatically charged material to capture pollutants in the air before they pass into your air conditioner or HVAC unit. The filter media is arranged in pleats to increase the surface area, providing more filtration per filter. Over time, as the AC air filter media gathers more pollutants, it becomes clogged, making it more difficult for the air conditioner to pull air through, making it work harder to cool your home. Because of this, the air conditioner filters should be changed at least every three months to avoid extra strain on your AC unit and reduce your energy to costs. If you live in an environment where you are doing remodeling, if it's allergy season, or if you have pets, you should consider changing the filter more often.
