Having an air filter in your home is a great way to improve the air quality and protect your HVAC system from potential damage. Air filters trap particles that are invisible to the naked eye, such as dust, pet dander, pollen, smoke, lint, mold, bacteria and more. Not only do they help purify the air in your home, but they also help those suffering from allergies or respiratory diseases such as asthma and hay fever. Air filters are usually made of spun fiberglass or pleated paper framed with cardboard for added stability and rigidity.
They are inserted in a specific location inside the return air duct (usually a large pull-down ventilation in the hallway or other place in the house). These air filters act as barriers to prevent contaminants from entering the HVAC system or circulating in the air. Most filters are designed to block particles of a certain size, which is determined by their Minimum Efficiency Report Value (MERV). The experts at David Gray Heating & Air have extensive experience and knowledge to help you with your air filtering needs.
US Home Filter recommends a MERV 8 rating at least on your home air filter to control average dust levels. Filters with higher MERV ratings trap small particles more effectively than filters with lower MERV ratings. One of the easiest and most economical things you can do to maintain your HVAC system is to change your air filter regularly. All Temperature Air recommends that you change your air filter regularly to keep your home and HVAC system running smoothly.
When most people say electronic air filter, they usually talk about an air purifier or an electrostatic air filter. The only type of filters that trap allergens and spores are HEPA, or high-energy particulate air filters. In addition to providing general information about the types of pollutants affected by air filters, this document discusses the types of air cleaning devices and technologies available, the metrics that can be used to compare air cleaning devices, and the effectiveness of air cleaning devices for eliminating indoor air pollutants and information from intervention studies on the effects that air filters can have on health and health markers. Now that you know the importance of replacing your air filters regularly, it's time to check and see if they need to be replaced today. Installing an air filter in your home is a great way to improve the quality of the air you breathe and protect your HVAC system from potential damage.
