I have been using these for years and loved them, till now. With this last package, we had issues with too much air flow restriction causing whistling and a louder, stronger air pull demand. Upon calling the Heating/Air service out, they advised that these pleated filters were the cause and to stop using them. Apparently there is no regulation for air flow and they have been advised by their (name brand) dealer to advise against using these.

Great

These do not fit a standard 14x14 vent

I hope these do the trick bc I have horrible allergies >> new filter plus new air purifier should do the trick.

These are very good filters. I change them every 2 months and they seem to help with dust and pollen.

Value, functionality, and convenience. Short of next weeks winning lottery numbers... What more could you ask for...?

I really like these filters does same job as air cleaner less cost. I noticed a difference in dust in the house and my allergies

Right size/Wrong fit: These were the size I needed, however when I got home they would not fit in the vent, so I had to return.

I am pleased with the 3 month life of these filters, and the app that will remind me to change them. durable and appear to be high quality.

These are great filters. They are thicker and sturdier that other ones. We change our monthly and they capture the dirt and odors. Cost is the best compared to home stores.
