Allergies, cats, litter, dust. All things that can be very aggravating. I have used these filters for several years and feel they really make a difference and worth spending a little bit more. I had them shipped and they arrived in a very sturdy 3M box which protected them from any damage. That box was inside a larger Sam's Club box. Definitely very well packaged! Usually this pack will help me get thru most of the winter.

I wish the filters were individually wrapped in plastic for storage. These are not, so once you open the package, you expose the other filters to allergens that are floating in the air. I put the unused new filters in a trash bag to keep them fresh until their time to be used in the ac. system.

I have been using these filters on my HVAC fr several years now, always purchased them at Sam's. I find them to be the best in dust prevention to my evaporator coils and keeping them clean and my HVAC working 100%. In our old Condo, dust is a major problem, I do no t want it to accumulate on my blower or my evaporator coils.

Bought on sale! Excellent choice.

Less dust and needs changing less often

Only filter we use! - Does wonders for the alergies!

Cheap construction for the price.

Great product. Works well. The thickness of the filter makes for a tight fit but I think that's actually better than having it too loose.

I bought these filters last month because I had a lot of dust ( new construction) inside house. I have noticed the difference already! Less dust!!

Glad you're find these filters on sale. It makes a big difference in the air quality inside my home. Feel great knowing it truly works.
