Frequently Asked Questions

How often should I change my Filtrete filter?

For maximum effectiveness, we recommend you change filters every three months. However, the life of a filter can depend on the individual conditions in your home. You may need to change your filter more often if your home has:

  • Unusually dirty duct work
  • Construction work in progress
  • Furniture or drywall sanding in progress
  • Pets
  • Smokers
  • A fan running continuously

In these cases, you may want to change the filter more frequently.

What is the difference between fiberglass filters and Filtrete filters?

Fiberglass filters were originally developed to protect your furnace and/or air conditioning system. They were not intended to significantly improve your indoor air quality. Filtrete filters were created to both protect your furnace equipment AND clean the air you breathe.

Our filters improve your indoor air quality by attracting and capturing allergy-aggravating microparticles. Your air is cleaned each time it re-circulates through the filter.

How do washable/reusable filters compare to Filtrete filters?

Surprisingly, even expensive washable/reusable filters canít capture microparticles as well as Filtrete filters can. The real difference is the electrostatic charge found in Filtrete filters.

Why does it matter that Filtrete filters are "electrostatically charged"?

Filtrete electrostatically charged filters have both positively-charged and negatively-charged fibers. The particulates in the air passing through the filter are either positively or negatively charged tooóand these charged particles stick to the filter. The charge helps pull more particles from the air than a filter without a charge.

Do Filtrete filters remove odors?

No. But in the case of tobacco and wood smoke, removing smoke particles can help reduce the odor.

Are Filtrete filters antimicrobial?

Filtrete filtering material will not support the growth of bacteria, mold, mildew or fungi in normal use. No unnecessary chemicals have been added to the filters.

Do I have to worry about restricted airflow with Filtrete filters?

If you use a Filtrete filter for longer than three months, it may begin to restrict airflow or cause your heating/cooling system to malfunction. It also could restrict airflow in some higher-efficiency air conditioning systems. When in doubt, change the filter more frequently.

Will a Filtrete filter eliminate the need for dusting?

Filtrete filters may reduce the need for dusting, but won't eliminate it. Atmospheric dust consists of a wide variety of particulates ranging in size from 0.001 micron to a relatively large 100 microns. Because of the weight of the large particles, they will settle on your furniture long before they could reach your filter.

How do Filtrete filters compare with electronic air cleaners?

The efficiency of Filtrete filters approaches that of the top-of-the-line electronic air cleaners.

Some tests indicate that in the large particle size range (1.0-10 microns), Filtrete filters are more effective. Price is a factor, too. Top electronic units cost 0 - 0 and require monthly maintenance. Filtrete filters cost a fraction of this price, and generally only need attention every three months.

Backed by extensive 3M research; independent testing and in-home use tests, each Filtrete Filter is designed to meet the specific needs of homeowners and businesses. Filtrete Filters are designed to achieve the proper balance between particle removal efficiency and pressure drop (air flow). An electrostatic charge is applied to the filter media fibers, which attract and capture airborne particles.

In Door Air Quality - You care about the quality of your indoor air, and Filtrete air filters ensure that you breathe the difference. The filterís electrostatically charged media attracts and captures large and microscopic particles, including pollen, mold spores, pet dander, bacteria, smoke and particles that can carry viruses and odors.

Air Conditioning and Furnace Filter Performance Ė Filtrete air filters help properly designed forced air systems function well by cleaning the air without excessive air flow restriction. All Filtrete filters have a pressure drop less than .20 on a water gauge which is less than most competitorís entry level filters.
