Believe they are better than my HD filters

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!

I have been using these filters for many years. Sam's Club is the most economical way to purchase them using Instant Savings.

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.

Im really happy with these filters

Really nice, quality filters

Got a four pack on sale great price.

The filter catches the dust well

Best pricing for the package

How great it was to buy four filters in a pack. They are not flimsy construction like most.
