Is 3M Filtrete a good filter?
Is 3M Filtrete a good filter?
1-inch Air Filters CR’s take: The Filtrete 1900 Maximum Allergen Reduction filter is impressive at removing dust, pollen, and smoke from the air when the HVAC system is running on its highest fan speed, earning an Excellent rating in that test. In both cases, air flow through the filter is strong.
Are 3M Filtrete filters HEPA filters?
This filter captures 99.97% of unwanted airborne particles, thanks to True HEPA filtration. It even captures particles 1000x smaller than you can see, so you can breathe cleaner, fresher air in your home.
What is filtrete MPR rating?
*Your filter’s MPR (Microparticle Performance Rating) indicates its ability to capture tiny particles between 0.3 and 1 micron in size. 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.
Is MPR the same as MERV?
MPR, or micro-particle performance rating, is a rating system developed by 3M. While MERV ratings reflect a filter’s ability to trap both microscopic and macroscopic particles, MPR ratings only grade a filter on its capacity to remove particles from 0.3 to 1 microns.
Are Filtrete filters electrostatic?
Most Filtrete™ Filters (those above MPR 300) have fibers with a permanent electrostatic charge. That charge lets filter media fibers capture teeny-tiny particles much more efficiently—without restricting airflow.
What does MPR stand for?
Microparticle Performance Rating
MPR stands for Microparticle Performance Rating, and it’s how Filtrete™ Brand reports a filter’s ability to pull in and trap tiny particles between 0.3 and 1 micron in size. For reference, an average strand of human hair is about 70 microns in size.
What are Filtrete HEPA filters made of?
Materials matter. Filter media is a mix of fiber and air, and it’s often pleated. In fact, Filtrete™ Filter media is less than 15 percent fiber; the rest is air. This very low density allows air to easily flow through the media.
What is the difference between true HEPA and HEPA type?
The main differences between HEPA-type and True HEPA filter are the filtration efficiency. In general, HEPA-type filter has a 99% efficiency rate of capturing particles as small as 2 microns. True HEPA filter up the game with a better 99.97% efficiency rate at particles as small as 0.3 microns.
What MERV rating is 3M 2200 filter?
MERV 12
The 2200 Elite Allergen filter carries a 3M Microparticulate Performance Rating of 2200 MPR (roughly equivalent to MERV 12).
