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 do both. They improve your indoor air quality by attracting and capturing allergy-aggravating microparticles, and help keep your furnace equipment clean. Air in your home is continually re-circulated through the filter, and is cleaned with each pass through the filter.
How do washable/reusable filters compare to Filtrete filters?
Surprisingly, expensive washable/reusable filters are similar to fiberglass filters in their inability to capture microparticles.
What does electrostatic really mean?
3M's electrostatically charged media contains both positively-charged and negatively-charged fibers. The particulates in the air passing through the filter will be either positively or negatively charged; therefore, the charged particles will stick to the filter.
Do Filtrete filters remove odors?
No, but in the case of tobacco and wood smoke, removing the 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.
How often do I need to change Filtrete filters?
The recommended change interval is three months. However, the effectiveness and life of the filter can vary and will depend on the individual conditions in your home. Unusually dirty duct work, construction work, furniture or drywall sanding, pets, the presence of smokers and running the fan continously are some of the things that can shorten the life of your filter. In these cases, change the filter more frequently.
