You should change your filters every 1-3 months. If you have furry friends, suffer from allergies, or live in an area with poor outdoor air quality you should consider changing every month.
Indoor air quality is often worse than outdoor air quality. By changing your filters regularly you ensure that the air you breathe inside your home is free of pollutants and harmful particles.
Changing your filters regularly will also increase the efficiency and longevity of your HVAC system. Dirty air filters can increase your energy bill by up to 15% and lead to costly repairs.
Your current air filters will have dimensions printed on the cardboard frame (for example, 20x20x1). If your filters have both “actual” and “nominal” dimensions, you want the nominal. Make sure to turn off your air conditioning or heating before you remove your current filter.
ChangeYourFilter.com offers the the highest quality filters available in every MERV rating (Minimum Efficiency Reporting Value). All of our filters are manufactured right here in the U.S.A. and inspected by our team before being shipped to your door. All at a price that is comparable or less than what you would pay at your local hardware store.
If you are unhappy with your new air filters for any reason we will gladly accept returns and exchanges within 30 days of the original purchase, so long as the filters have not been used or damaged. Please reach out to firstname.lastname@example.org with your order number and reason for return or exchange.
First, turn off your heating or air conditioning system and gently remove your old filter. It is a good idea to place it directly into a garbage bag to prevent dust and particles from releasing into your air.
Next, find the arrow on your new filter that indicates the proper air flow direction and insert the filter accordingly. The arrow should face toward the furnace and away from the air duct that is carrying the air in need of heating or cooling.
Tip: It is a good idea to draw the airflow direction with a permanent marker on the outside of your furnace housing.
MERV stands for Minimum Efficiency Rating Value. The higher the MERV rating, the more efficiently your filter will trap airborne particles. For example, a MERV 8 filter will efficiently trap most pollen, dust, dust mites, and mold spores. A MERV 13 filter, on the other hand, will trap everything that a MERV 8 traps, in addition to pet dander, tobacco smoke, smog, and airborne viruses. Most energy and environmental agencies recommend a MERV 8 filter at a minimum, while the U.S. Department of Energy recommends a MERV 13.
