Answer: 3M Filtrete filters should be changed every 3 months, unless conditions within your home make it necessary to change more frequently, such as having pets, smokers, or family members who are sensitive to allergens.
Do Filtrete filters restrict airflow?
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.
Are Filtrete air filters worth it?
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. Airflow through the filter remains strong in both instances.
How long do thick air filters last?
Thicker filters can last longer than thinner ones. Here’s a rough estimate on how long one can last, based on its thickness. Filters that are 1 to 2 inches thick should be replaced every 1 to 3 months. Filters that are 3 to 4 inches thick should be replaced every 6 to 9 months.

Are 3M Filtrete filters made of fiberglass?
3M Filtrete filters contain electrostatically charged filter media made of polypropylene and polyolefin plastic, and capture particles that measure between 0.3 – 10 microns in size.
Are pleated filters better than fiberglass?
While fiberglass air filters will do the job in the most basic way, in most cases, pleated air filters are much better. They can filter out smaller particles – important for people with airborne sensitivities. They are less likely to clog in a short amount of time, and they can last up to 90 days.
Why are filters pleated?
By pleating the media, these filters can have an increased surface area and density while minimizing the reduction in airflow. In other words, pleated filters can collect more particles than standard throwaway filters without increasing your air conditioner’s energy consumption.
Why are Filtrete filters so expensive?
Furnace filters have been getting more effective in collecting dirt and dust particles since at least the early 1980’s, with corresponding increases in costs of production and profits and costs. The smaller the particle that the filter will trap, the more expensive it is to produce and buy.

How effective are pm2 5 filters?
When used with a fitted cloth face mask made to pm2. 5 specifications, a carbon pm2. 5 filter is capable of achieving up to 90% filtration in the critical fine-aerosol range.
How long do pm2 5 filters last?
Disposable PM2. 5 filters are flat, so they take up less space than standard respirators. They retain effectiveness for years, and you can use them continuously for 16-24 hours (around 1 – 2 weeks of occasional use ), or whenever it becomes harder to draw a breath.
