This particular filter has been remarkable in keeping the dust and allergies at bay in my home. The company that takes care of my heat and air filters approves this filter as being suitable for a particular purpose of dust and allergy control. It is not to thick and blocking air flow but thick enough to control dust particles that cause allergies. Thank you.

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 buy these when they are on sale. They are great because they filter out all of the allergens. We do not have pets but when visiting friends/family, pet hair & dander can be brought home, along with environmental elements. My daughter & I are very sensitive, we have central air through our furnace, so the filters are used during heating & cooling. I but them year round.

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.

Love them, visual difference in the air. You know how the sun shines through the winfow and you can see particulates in the air...well not with these beauties. The only drawback to how well they work is that they will not go 90 days. Due to the proximity to a major interstate highway we get a lot of dust, but i would rather change the filters more often (45 to 60 days) than have to breathe all that junk like when we used cheap filters. My allergies are also much better, still have to go outside so I dtill have some issues but not like previously.

I don't know about you, but I change the filter on my gas furnace the first of each month. Buying in bulk is a great idea; now I always have the next filter. The allergen dust filter is especially a boon since we're indoors so much more with the virus and weather. Thank you Sam;s Club

Every day is allergy day in Southern California and we need the most protection a filter can give for our A/C and heating needs. We are worth it and so is the difference that these upgraded filters offer us. After all, breathing is one of the most important things that we need to do !

Hey there it’s me CharlieT, I used to purchase the wide filters 4x4 by HoneyWell. I will never again they are supposed to last a year, however since I have been buying Filtrate filters we have seeing a different. Less dusk, fresher air, we haven’t been sneezing or couching. I highly recommend Filtrate filters.

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

Cheap construction for the price.
