Typically, HVAC companies recommend changing your the filters in your home once every 90 days, or roughly every 3 months. Regularly changing your air filter not only ensures better air quality but also helps your HVAC system operate efficiently, saving you money on energy bills in the long run.

Over 80% of Americans neglect to regularly change their filter, mostly because it's so easy to forget. Our subscription service conveniently delivers high-quality American-made filters right to your doorstep so you never have to remember.

A MERV rating between 8 and 13 is suitable for most homes. Higher MERV ratings trap more particles, but can also be more restrictive on older HVAC units.

• MERV 8 captures larger particles such as dust, pollen, mold spores, and lint.
• MERV 13 filters finer particles like smoke, bacteria, and some viruses.
• VE3 is a high-performance antimicrobial filter that neutralizes viruses (like COVID-19) while maintaining airflow and long life. VE3 is MERV 11 rated with MERV 13 antiviral capabilities.
  

Your filter size is usually printed on your old filter's frame or can be measured (width × height × depth in inches). We also provide a sizing guide to help you measure correctly.
