When it comes to improving the air quality in your home, an air filter is an essential component. It works by trapping impurities such as dust, pet dander, bacteria, and other invisible particles from the air that flows through the system. Not only does this help to improve the air quality inside your home, but it also protects your HVAC system from damage. Understanding the different types of air filters for homes is the first step to getting the best indoor air quality you deserve.
The quality and quantity of the filter medium influence the size of the air particles that can be captured, the way they are captured, and the air flow through the system. Air filters are usually made of spun fibreglass or 26% pleated paper framed with cardboard for greater stability and rigidity. In general, high-efficiency filters that are also cost-effective are best for homes, but other considerations should include whether there are pets in the home, if mold or mildew poses a threat, and how often filters should be changed. The most effective ways to improve indoor air are to reduce or eliminate sources of contaminants and to ventilate with clean outdoor air.
Air filters are an aftermarket product with a longevity that usually lasts 1 to 6 months for disposable filters. In general, filters will be 1 inch thick for common systems and 5 inches thick for larger HVAC systems. In general, most air filter manufacturers and HVAC companies recommend changing the air filter every 90 days or 3 months. We evaluate how well an air filter removes dust, pollen, and smoke from the air, and see how freely air flows through the filter at any fan speed.
When it comes to air filters for HVAC systems, media filters can offer more benefits than standard filters with high MERV ratings. For this reason, these filters are not recommended for people who have respiratory problems and need a filter that improves indoor air quality. The pleats of these filters give them an advantage over pleatless options because they increase the surface area of the filter for better filtering. The best filters trap indoor contaminants such as dust, pet dander, pollen, and other allergens and spores. In general, filters with a MERV 16 rating or lower are considered suitable filters for HVAC systems for residential, commercial and general hospital use.
HEPA (high-energy particulate air) filters are also available for those who need a filter that captures allergens and spores. Choosing the right type of filter is essential for ensuring your home has clean air that is healthy and easy to breathe. It is important to consider factors such as whether there are pets in the home, if mold or mildew poses a threat, and how often filters should be changed when selecting an air filter for your home. Additionally, it is important to remember that most manufacturers recommend changing your filter every 90 days or 3 months.
