Why Reliable Airflow Matters
Cleaner indoor air:
Optimal air flow allows filters to do what they’re meant to do: Capture airborne particles and deliver cleaner air for your space.
Easy on your HVAC:
Reliable air flow prevents strain on your HVAC system, reducing wear and extending its life. A happy HVAC leads to reduced energy usage and utility costs.
Quality Materials Matter
The Filtrete™ Brand takes pride in using high-quality materials, from crafting the filter fibers to perfecting the final product. “It allows us to innovate and develop every step of the way,” explained Kelsey Hei, Filtration and Indoor Air Quality Specialist. “We can ensure that we meet the quality standards at every checkpoint.”
With complete control over design and product, every detail is optimized for consistent, reliable performance. This precision is why Filtrete™ Filters are the trusted choice for cleaner air.
The principles of elector static charge are integral to Filtrete™ Filters, enabling them to attract and capture even the smallest airborne particles – think of allergens like pollen, pet dander and dust mite debris. Much like the statically charged balloon picking up small pieces of paper, this charge enhances the filter’s ability to trap airborne particles while keeping airflow smooth and uninterrupted. Every filter is engineered with the the principles of an electrostatic charge and surface area using pleats to best balance particle capture, airflow and necessary filter life.
You may have heard that higher efficiency filters restrict airflow. It’s true that many brands have more restricted airflow with a higher MERV rating, but not all. Filtrete™ Air Filters have similar airflow across all MERV and MPR levels. Built using our trademark 3M Science, our design delivers both exceptional particle capture and fluid airflow, so you don’t have to compromise.
“Think of it like a brick wall. Most filters have to restrict more to get those particles captured,” Hei said. “But with us, we can balance efficiency and airflow because we own our process and innovation.”
To measure performance, we use two rating systems: the industry-standard Minimum Efficiency Reporting Value (MERV) and our own Microparticle Performance Rating (MPR). Higher MPR ratings mean better particle capture, ensuring your indoor air quality remains top-notch.
Remarkably, some of our higher-rated Filtrete™ Air Filters (with elevated MERV and MPR ratings) actually allow better airflow than lower-rated filters,” Hei said. With Filtrete™ Air Filters, high performance does not lead to reduced airflow, giving you clean air without overworking your HVAC system. With Filtrete™ Air Filters, you can truly have it all.
The best thing you can do for reliable air flow
Apart from choosing the right Filtrete™ Air Filter for your home, the best thing you can do to ensure continued optimal air flow is to change your air filter regularly. Unfortunately, your air filter can't replace itself, so you need to stay on schedule.
Neglecting your HVAC filter is like skipping oil changes for your car, and that is a recipe for disaster. A clogged air filter results in inadequate airflow, which can cause issues like frozen coils and overheated HVAC motors. Replacing your air filter proactively assures optimal air flow and HVAC performance. If you cook frequently, conduct home renovations, have pets or live in an area with poor quality, you'll want to change your air filter more often. Don't hesitate to check your air filter frequently, and replace it if it's visibly dirty for instant gratification. If you're questioning the size of your filter opening, pull out your trusty tape measure and check to find the correct filter size for your HVAC unit.

In May 2025, Wirecutter praised the performance of our MPR 1900 / MERV 13 Air Filter, naming it the top pick among air filter brands it tested against.
“Filtrete’s HVAC filters are widely available online and in stores, and they come in a huge range of sizes. We recommend the MPR 1900 Air Filter, which is rated MERV 13 – the highest level of filtration that can be used in most HVAC systems. Better filtration generally means a filter has a higher air resistance that can put a strain on HVAC equipment. Filtrete’s MPR 1900 Air Filter, however, have the lowest resistance we've seen among MERV 13 filters – even better than most lower MPR filters which don't capture fine particles nearly as well.”

FAQs About Airflow
-
Do high-efficiency filters negatively affect airflow?
Not with Filtrete™ Air Filters! Our advanced design ensures clean air without overworking our HVAC system.
-
What makes Filtrete™ Air Filters different from other air filters?
Filtrete™ Filters Are designed to balance electrostatic charge and the surface area of the filter material, ensuring effective particle capture without compromising airflow. Even our higher MPR-rated filters maintain proper airflow while trapping the smallest particles. Plus, we provide clear performance metrics on our packaging so you can choose with confidence.
-
How can I ensure optimal airflow?
Replace your air filter regularly, and check that your filter is the correct size for your system. Here’s how.
-
How often should I change my air filter?
For top performance, replace 1” air filters every three months or sooner, and 4”+ filters every 12 months or sooner. If you have pets, smokers, have done home renovations, or are continuously running a fan, change your filter more often to keep cleaner indoor air.
