Knowing what kind of HVAC filter you need can be a little overwhelming. After all, there are various different sizes, ratings, and capabilities. Because changing your air filter is the single best way to keep your HVAC system working properly, we’re sharing a guide to help you select the right filter for you so you can be confident it’s doing the best job it can all year round.
Different Types of HVAC Filters
Fiberglass: Fiberglass filters are disposable and more affordable than other options. However, they work better to protect your air conditioner than filter dust and pollutants in the air. This type of air filter might leave you and your family subject to respiratory problems.
Pleated: Made of polyester and cotton folds, which filter out dust and other pollutants. When shopping for a pleated filter, you’ll want to look for ones with the most pleats for the best performance.
Washable: Washable filters cost a little more than disposable ones, but you save in the long run. When investing in washable options, it’s important to plan washings ahead of time and allow plenty of time to dry to avoid mold growth and bacteria build-up.
Electrostatic: Looking for a different way to trap dust and particles? An electrostatic filter does so by creating a magnet charge. They come in washable and non-washable designs and can be very effective.
HEPA Filter: If you or someone in your family suffer from allergies or a respiratory illness, a HEPA filter would be the best option for your home. These filters are high efficiency and are effective at screening contaminants up to 99.97%.
UV Filter: A UV filter uses ultraviolet light to kill bacteria and viruses in your home. However, it’s less efficient at screening dust and contaminants. All in all, they are great for combating viruses that can be harmful to your health.
How often should I change my air filter?
This answer depends on the type of air filter you have. If you use a pleated or high-efficiency air filter, the rule of thumb is to change it every three months for maximum air quality and efficiency. During peak allergy months, it’s recommended you check your air filter sooner to change it more often if it looks dirty.
