Really nice, quality filters

Great buy for this type of filter and size, this price beat everyone!

Nice quality and price in quantity.

Got a four pack on sale great price.

Needed for our coffee. Pricey, though

The filter catches the dust well

Good filter. Sturdy. Helps with family members allergies and asthma. Good product for a good price! Catches everything we need on a daily basis. We did upgrade just for the summer last years when dealing with wildfire smoke and the 2.5 particulate. Then back to these!

They fit the opening OK and seem to work fine. I can't tell by using them if they do or do not capture allergens, bacteria and viruses.

Nothing negative to say about this purchase.

it is okay but put pressure on ac suck fan
