Noticed a huge difference in air quality even with having 4 cats. Love that I was able to buy a years worth of filters for cheap AAAND the company will send me more filters in a years time. We no longer have to remember what size is needed and we dont have to worry about forgetting to get a filter when shopping. Truly gives you one less thing to worry about! THANK YOU

It makes a distinct whistling noise when the system is running compared to the Filtrete filter it replaced. Only had it a few days. Bummed about the whistling noise.

I purchased these filters for my Mother (lives in FLA), so I'm not using them myself. I CAN SAY that the delivery was very quick. Mother did mention that they were 1" smaller than the one being replaced ... I doubt that will affect the efficiency.
