[This review was collected as part of a promotion.] They fit my central air system and do not distort or move like the cheap fiberglass filters and are renewable with a garden hose and a spray nozzle to rinse them and allow to dry and reuse them with a much better filtration.

Work great and helps contain any dust! Is washable so continuous use is a money saver! Fits perfectly in the Return Air Vent box

This filter will pay for itself in two months. You wash it , let it dry and reinstall,easy. Buy this one.

I was having so much dust coming from the vents in my home so I knew I had to do something . I started looking and found these filters that are a little higher than I wanted to pay, but I have Asthma so the dust had to go. The filter has helped so much and I was so amazed and happy. Thank You

I purchased two filters to always have a clean one on hand. The airflow thru these filters are so much quiter, easy to use, and easy to clean. Plus, our family is saving money with never having to buy filters again.

it is great easy to wash and clean only to use again and again...

very well made washable filter that fit perfect.

well built with sturdy materials

I really like that this filter will last me for years, and that I don't have to create more waste every time I change a filter. The filter was very tight in my furnace though, it took me a little extra work to get it to fit properly.

This filter wirks until you wash it. i will be going back to the 3M fikters! this is so horrible.. DO NOT BUY THIS!!
