Have you ever thought about what type of air filter you are picking up for your home? I’m not talking about the brand you are getting, but rather the MERV rating that you are getting. The Minimum Efficiency Reporting Value (or MERV) rating is a rating system used to compare filters made by various manufacturers. MERV ratings will range from 1 (low efficiency; minimum filtration) to 20 (highest efficiency; highest filtration).
For most household uses, the highest MERV rating used will be MERV 13 filters. Keep in mind that a MERV rating higher than 13 could negatively affect some HVAC systems, so it is advisable to verify that your unit can handle a higher rating before you make your purchase.
According to Alex Hertzog, our in-house air filtration expert, MERV 11 filters are recommended.
“The MERV 11 air filters remove a higher percentage of contaminants in the air that will increase indoor air quality and maintain the efficiency of the HVAC unit. It is also highly recommended if there are pets in the home, which can greatly reduce the air quality in your home.”
The chart below shows what you can remove from your air with MERV 8, 11 and 13 filters.

Now is a perfect opportunity for seasonal home maintenance, such as changing your air filter. This is especially important during the fall season as many allergies begin to worsen. When it comes to buying the correct air filter for your house, there are three questions you should ask.
1.) What size do I need? The most difficult decision is often finding the correct air filter size for your home. When considering this, always keep in mind the difference between nominal filter sizes and actual filter sizes. What is the difference? According to Cartier King, our in-house air filter expert:
“Nominal sizes are used to help identify a filter’s size more conveniently. The nominal size of a filter is usually rounded to the nearest complete inch. The actual size of a filter is most often smaller than the nominal size and varies between different manufacturers. For example, a 20x20x1 Filters Fast MERV 8 filter actually measures 19.56” x 19.56” x .75. The best way to ensure that your filter will fit is to measure the opening of your unit (or your old filter) before you make your purchase.”
2.) Has my HVAC Unit been maintained properly? Be sure your air and furnace system is well maintained before installing a new filter. A system that has not gone under a regular maintenance schedule will negate any affect a new air filter can have in your home. You should also keep in mind that older systems are not usually designed for higher grade filters. Be sure to check with a professional about which type of filter you should use.
3.) Will this filter help my allergies? Not all air filters are specifically created for removing allergens in the air. If you suffer from severe seasonal allergies, installing a filter designed to remove many indoor allergens will be a wise decision. Consider the Filtrete Ultimate Allergen filter or the Filtrete Micro Allergen Air Filters, which will both effectively reduce many airborne allergens from circulating in your home.
