    2 Simple Ways to Remove Dust Allergens with Your AC

    2 Simple Ways to Remove Dust Allergens with Your AC

    If you have multiple general HVAC service questions, one of them probably revolves around making sure your indoor air is as clean as possible. During the spring season, many individuals wonder how they can use their air conditioner to help reduce the number of allergens in their home or office. Let's discuss two of the simple methods to remove allergens from indoor air.

    #1: Upgrade the Air Filter

    The air filter should remain as clean as possible to provide the air conditioner with the most effective opportunity to remove contaminants from the indoor air. But to have your HVAC system do an even better job cleaning the indoor air, you should consider upgrading the air filter.

    Choosing an air filter depends primarily on its minimum efficiency reporting value (MERV) rating. The MERV rating determines how effective the air filter is at removing particles from the air. The higher the MERV rating, the smaller the particle the air filter can remove. As you might expect, air filters with lower MERV ratings can only remove the largest of contaminants floating in the air.

    To find an air filter that will do a better job removing allergens from the air, you may want a filter with a higher MERV rating. But don't try to choose the air filter with the highest rating possible. Filters with extremely high ratings, such as 18 or higher, don't necessarily do a better job at removing allergens from the air than a lower-rated air filter, such as 10 or 12. Not only is a higher MERV rated filter a waste of money, but it can also make the HVAC work harder, reducing energy efficiency.

    #2: Maintain Constant Air Circulation

    Even when you don’t want your HVAC to cool the air, it’s best to keep the air moving indoors. You can do this by keeping your HVAC fan on at all times. This allows the filter to continue purifying the air even if the air conditioner is not cooling the air. The more air that can pass through the air filter, the more allergens the air conditioner can remove from the indoor air. There is also the added benefit of allowing the air conditioner to remove excess moisture from the air, which can help reduce certain allergens, such as mold.
