Holmes HAPF30AT Air Filter, Pack of 1, White

These will fit the whirlpool model, if you break off the tabs on the sides. They’re a lot cheaper too.

IT WORKS GREAT

Be warned it is not a miracle cure. If you have severe allergies you will probably need a more heavy duty purifier with better filters. I still have to dust just as often and I dont have allergies so I havent noticed a change there. It does help a bit with pet odor though. Im just not sure how much of the odor protection is from this filter and how much is from the carbon prefilter. I will say this though, unless you have really bad allergies you can probably let the filter go a while. I let the cheap blue one that came with it go about twice as long as what the directions said and didnt notice any problems. One thing to try first though, if you are considering these just for allergies and you have mild ones, you might want to check and make sure that your hvac filter is around a merv 8 to 10. It might be cheaper to just get better hvac filters than to get these and the air purifiers. Try that especially if you have the cheap blue ones that are ofter merv 1 or 0. Also you can buy hvac filters and tape them to those square box fans and it will work as an air purifier too. I would suggest that more for allergies though. I got this because we have pets and I dont know if its the arm and hammer in it or what but it seems to take the edge off the smell.

Great filter that definitely does help purify, but it doesn’t seem any more effective at odor elimination than the standard filter by this brand

Filters say replace in 6 months, after 1 month the whole outside unit is full of dust. Must be replaced monthly! I have my brand new house cleaned 3 times a week and these filters are still fill up and are black. WHY??? They use to last 6-8 months and were only slightly gray. So disappointed!

This filter works great to eliminate pet and smoke odors. It has no scent but that’s a good thing as it’s supposed to eliminate odors, not introduce new ones.

Does exactly what it is supposed to do

Was looking for replacement filters for my older Holmes Fan/Air Purifier. Originally it came with Type A filters, but Holmes has since upgraded to their AER1 line. I had trouble deciding on a type, as I was confused why, of all the options, it seemed like some of the filters did the same things but for different prices. One BIG DIFFERENCE I discovered after ordering these filters, is that the recommended replacement time is different for these filters: 4-month replacement: Odor Eliminator, Smoke Grabber, Total 12-month replacement: Allergy (Allergen Remover), Allergy Performance Plus There are other distinct differences which I found very hard to locate: -- all the 4-month replacement filters seem to have 99% filter strength, -- the 4-month replacement filters are HEPA-type filters (not authentic certified, just very similar) -- the 12-month filters (allergen remover & performance plus) filter 99.97% and 99.99% of allergens, respectively, -- the 12-month filters are True HEPA filters, -- the Odor & Smoke filters seem to have carbon and Zeolite infusion, Most all of the filters are going to filter the same things, the difference is just how good you want the filter to be, and what you want to filter: -- debris and allergens -- pollen, dust, debris, dust mite debris, mold, pet dander, smoke, VOCs (like cleaning product chemicals in the air). -- odors -- tobacco smoke odors, pet odors, dirty laundry odors, and cooking fumes. If I were to rank the strength of the filtering ability, I would rank them the following way (with 5 being the strongest filter): (1) Total Air, (2) Odor Eliminator, (3) Smoke Grabber, (4) Allergen Remover, (5) Allergy Performance Plus ---> But it is worth noting that the Smoke Grabber and Allergen Remover filters do not include Arm & Hammer infusion, and the Allergen Remover filter also does not claim to reduce odors from pets, tobacco smoke, cooking fumes and other unpleasant household odors. For me, the Odor Eliminator was the cheapest filter (currently $8.99 for a pack of 2), and I didnt have any huge specific needs to filter one thing more strongly than another (like allergies, odors, or fumes), so I just got the basic filters to keep my air clean. However, knowing that the Performance Plus needs to be replaced only every 12 months, it would have made sense to get that for $18.99 for a pack of 2...

No dislikes. Replacement for my air purifier.
