3M 9805-4 Filtrete Pleated Allergen Air Filter, 1-Pack - 14 inch W x 20 inch H x 1 inch D, 11 MERV (Pack of 4)

Opt for a Filtrete Allergen Defense Air Filter to transform your central heating and cooling system into a whole home air filtration operation. This no nonsense filter helps capture varying sizes of particles, from the large (lint, pollen, dust and pet dander) to the microscopic (smoke and smog).

• #1 Recommended Brand* (*Filtrete Brand is the most recommended brand of HVAC Air Filters based on the US Filtrete Brand Health Tracker, Ipsos, June 2022)
• The higher the MPR, the more microparticles--such as pollen, pet dander, smoke, bacteria and viruses--your filter will capture from the air passing through it
• For optimal performance of your heating and cooling system or HVAC system, change your home air filter at least every 90 days for 1 inch filters
• A dirty filter will slow down air flow and make the system work harder to keep you warm or cool--wasting energy. Sign-up for a filter change reminder program (www.filtrete.com/ChangeReminders) that works for you!
