These were too big for my opening. I returned them.

The filters work very well catching most of the dust and other allergens!

Not nominal size as printed on package, ONLY FULL ACTUAL size, had to return!

Lasts up to 3 months but have to change every month.

way cheaper than buying them 1 at a time and good quality

Good price for quality filters

Great price and great product

These filters work well and are a good value

Excellent filter, removes a remarkable amount of dust.

They work well and reduce dust in my house.
