This no-nonsense filter helps capture varying sizes of particles, from the large (lint, pollen, dust and pet dander) to the microscopic (smoke and smog).

Lots of air flow, does a great job blocking even super tiny dust. Just what you'd want and expect.

The Filtrete 18x20x1 AC Furnace Air Filters (MERV 11, MPR 1000) are a must-have for maintaining clean and healthy air in my home! These filters do an excellent job of trapping dust, pollen, and other allergens, making a noticeable difference in air quality—especially for those with allergies.The electrostatic design works great at capturing small particles, and they last a full three months without any issues. The pleated construction makes them more efficient and durable than standard flat filters, and I appreciate that they come in a 4-pack, so I always have backups ready.Installation is quick and easy, and the actual size fits perfectly in my HVAC system. If you’re looking for reliable, high-performance air filters that help keep your home’s air clean and fresh, I highly recommend these! Great value and great quality! 💯🏡🌬️

The Filtrete Furnace Air Filter is fantastic when it comes to maintaining the air quality in my home. The filter is solidly built with a premium design that effectively captures dust, allergens, and other particles, leaving the air feeling fresh and clean. I’ve noticed a significant improvement in air quality since switching to Filtrete, and my HVAC system seems to be running much more efficiently.While the manufacturer recommends changing the filter every 90 days for optimal performance, I've found that replacing it every 30 to 45 days offers even better results. Doing this helps keep the airflow even cleaner and the system running at its best. The extra investment in changing it out more frequently is well worth it for the noticeable difference in air quality and reduced dust in my home.If you want the absolute best performance from your furnace air filter, I highly recommend swapping it out every month or 45 days. The Filtrete Furnace Air Filter is a top-quality product, and more frequent changes make it perform even better!

Decent quality filter which usually lasts the full 90 days before needing a change. While still pricey overall these are cheaper than the big box stores.Tip: It helps to write the date on the edge of your filter so you remember exactly when it was changed.

I bought these because I wanted a thicker filter for our furnace during cold weather. The concern is mainly indoor dust and bacteria getting recycled into the house. This filter works very well.
