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). Actual filter depth is 4.31".

• Actual filter size is: 19.875 in x 24.625 in x 4.31 in
• This filter is compatible with Honeywell® furnaces calling for a 4" filter, and Lennox® furnaces calling for a 5" filter
• 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 & cooling system or HVAC system, change your home air filter at least every 12 months for 4 in. and 5 in. 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!
