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 !

I LOVE these filters! They catch so much particulate that I can breathe so easy. My last filters had my allergies acting up worse because they only caught half of what was floating around. These ones can make it so easy to breathe, it is like I do not have allergies!

We couldn't figure out why there was an extra layer of white dust on everything along with excessive sneezing. Took us a few days to locate problem and we change filters every 30 days. This filter has loose fibers on one side and the fibers blew all over the house every time the AC turned on. We had to dust every day and I hate dusting lol. Great price but didn't work for us.

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

Use these in a 2 unit apartment house with individual furnaces that where installed a year ago. These new units move air at a higher velocity then old ones and the filters really capture all the dirt, these need to be changed monthly in the heating season

Not the quality you'd expect from Filtrete. These were cheaply made with poor workmanship. The filtering material was so thin there was some holes and many almost holes where it somehow was stretched on the outer peaks of the V creases. Notice the only show one side, that is because a paper brace to match the paper back braces are missing so the collasp strenth is weak and the filter noticably sinks inward when new and clear under normal airflow. My order of 20x30x1's were slightly oversized so they were a bit too big for the opening so they had to be force fit that crumpled the edges a bit. I won't ever buy these again and probably will just go back full time to the better quality Honeywell brand I normally pickup locally for abt the same price. Shoulda known better. Now I do.

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.

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.
