Filtrete™ Air Filters have delivered cleaner air for over 30 years. Today millions of homes

utilize these filters and Filtrete has become the #1 most trusted and recommended

residential air filtration brand in North America today.*

 

Filtrete™ Air Filters are the only air filter to include BOTH MERV and MPR ratings. MPR

stands for Microparticle Performance Rating, and measures an air filter’s ability to capture

the tiniest particles between 0.3 and 1 micron in size contained in the air passing through

the filter.

 

Filtrete™ Air Filters capture more particles than the industry minimum standard, without

compromising additional airflow in your system.** What does that mean for your

customers? Cleaner air, without overworking the HVAC.

 

Filtrete™ Air Filters come in various depths, from 1-6” pleated filter sizes. We recommend

changing air filters at least every 3 months for 1” filters and 6 months for 2”+ air filters.

For easy replacement reminders, create a filter change countdown from the Filtrete Smart

App. Simply use the app to scan the barcode on the filter’s package, then choose 30, 60, or

90 days for your 1” replacement countdown or a 3, 6, or 12 month reminder for 2”+ sizes.

**Filtrete™ Air Filters exceed MERV minimum particle capture requirements.

Products We Love

These capture more allergen, bacteria and viruses compared to lower rated Filtrete™ Air Filters. They outperform by capturing 24% more microparticles than the MERV 13 minimum requirements.

 

Also, these are Certified Asthma & Allergy Friendly®, validated from independent testing, specifically focused on particles of asthma and allergy triggers and overall indoor air quality.  These filters have been barrier tested in a test duct with dust containing common allergens to meet the following minimum performance levels.

  • Allergen & Particle Removal: Removes at least 95% of pollen particles, 92.5% of house dust mite allergen particles, 85% of cat allergen particles and 40% microparticles.
  • Load Performance Testing: Filter’s airflow resistance must not increase by more than about 20% in a laboratory dust loading test.
  • Seal Integrity Testing: Ensure air is passing through the filter rather than around it, the filter is covered with an impermeable barrier and air is forced toward the filter to check for leaks. Air bypassing the filter must remain below 10% within 30 seconds.

These capture more allergens such as pollen, mold spores, pet dander and dust mite debris compared to lower rated Filtrete™ Air Filters. They outperform by capturing over 2x more microparticles than the MERV 11 minimum requirements, while delivering reliable airflow.

 

These are also certified Asthma & Allergy Friendly®, validated from independent testing, specifically focused on particles of asthma and allergy triggers and overall indoor air quality.

These filters provide a good balance between air filtration efficiency and airflow.  These are sufficient for many residential and commercial environments where allergens may be less of a concern.  These filters capture more dust, pollen and pet dander compared to lower rated Filtrete™ Air Filters, and even capture 4x more small particles (0.3 to 3 microns) than the MERV 8 minimum requirements, all while ensuring consistent and reliable airflow.

These kits comes with a reusable air filter frame and two collapsible MPR 1550 air filters to get homeowners started with capturing 42% more microparticles with 20% less waste.* Also, certified Asthma & Allergy Friendly®, the collapsible refillable filters take up 75% less space, saving space and money on refills throughout the frame’s designed 20 year life span.** Changing filters is a breeze with less than a minute assembly, and the Filtrete Smart App can alert when it’s time to refill.  These currently come in 16x25x4 and 20x25x4 sizes, replacing a range of 4-5” marked air filters. Who said a small change can’t make a big impact?

 

*More microparticle capture than MERV 12 minimum requirements. (Microparticles are 0.3- 1.0 microns in size.) 20% less waste than traditional Filtrete™ Air Filter by weight

**Less than comparable sized traditional Filtrete™ Air Filters, based on MSRP. Excludes damages, abuses, or alterations.
