Filtrete™ Allergen WMTDP03-4IN-2, 20 in x 25 in x 4 in (50.8 cm x 63.5 cm x 10.1 cm)

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).

• Outperforms fiberglass, washable and non-electrostatic 3-month pleated 1" home air filters for your furnace, air conditioner, or HVAC system
• Exclusive Filtrete™ Brand 3-in-1 technology from 3M traps unwanted air particles, letting cleaner air flow through
• Filtrete 1200 MPR has a rating of MERV 11
• 1000 and 1200 MPR also available in 4”, 4” slim fit and 5” air filters
• For optimal performance of your heating & cooling system or HVAC system, change your home air filter at least every 90 days for 1” filters, and at least every 12 months for 4” and 5” filters
• For residential use only
• 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
• 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!
• CREATE A CHANGE COUNTDOWN in the Filtrete™ Smart app. Simply use the app to scan the barcode on your filter’s packaging, then choose 30, 60 or 90 days for your replacement countdown. When the lifespan is up, you’ll get a notification to change your filter
