I place them behind the box fan and replaced the filter once a month. This fan ran 24 hours a day. At the end of the month the filter will be visibly gray and it helped with my allergies.'}, {'review_meta': 'Reviewed in the United States on December 17, 2016', 'review_star': 'a-icon a-icon-star a-star-5 review-rating', 'review_body': 'It is often a pain buying filters for the AC/furnace: more economical to buy a bunch, prices vary, ratings vary, brands vary . . . and you throw out the filter in a month or so! You just want it to work. I thought I would order some online through amazon and it worked out wonderfully. They were reasonably-priced and I got a higher R rating for the product than a lesser rating at a greater price. It arrived on time. No damage. And the filters work! This will be my source for future filters.'}, {'review_meta': 'Reviewed in the United States on April 7, 2018', 'review_star': 'a-icon a-icon-star a-star-1 review-rating', 'review_body': 'Filters are NOT the described size. They are SMALLER than listed and will not correctly replace OEM filters. Also, mine were also defective as the glue holding the ends of the filter paper to the frame had already let go, so there were gaps between the filter paper and the frame in which air could by-pass the filter entirely. Also, the shipping box was not reinforced on the corners, so where the corners of the shipping box were crushed, it meant that the filters inside were crushed also. Unless your a/c unit requires a filter that is smaller than 20x25x4, do not order - they will not fill the entire void in the duct, which mean air will just go around the filter.'}, {'review_meta': 'Reviewed in the United States on February 10, 2019', 'review_star': 'a-icon a-icon-star a-star-5 review-rating', 'review_body': "Had an old washable hog hair filter that originally came with my Carrier heat pump system for 10 years. Decided to replace the old hog hair with a proper disposable paper filter. Called Carrier so they could suggest a MERV rating as not to put to much strain on my system/blower motor etc. Carrier HAD NO IDEA and said to call my local HVAC folks. My local guy (as I) believed a MERV 8 should be plenty fine and not do damage to my system. The filters came today and I ran an airflow test through my advanced thermostat only to find the MERV 8 was far too much filtering for the system (see pics).\n\nLooks like HAVE to go back to my high flow through fiberglass filter but at least I can ditch my old washable hoghair AND I don't have to worry about if I'm putting excess strain on my HVAC System. Hope this helps!!\n\nNice filters! Fit exactly as I thought. Be careful with higher MERV ratings though!"}, {'review_meta': 'Reviewed in the United States on March 2, 2021', 'review_star': 'a-icon a-icon-star a-star-5 review-rating', 'review_body': 'We have an odd ball size, and these filters are perfect, we preferred We prefer Merv 6 (old school green fiberglass filters) but this is the next step up cause they dont make merv 6 in the size we need.\nKeep in mind the higher the Merv rating the hard the fan inside the handler has to work thus using more electric and burning the fan motor up.'}, {'review_meta': 'Reviewed in the United States on December 24, 2021', 'review_star': 'a-icon a-icon-star a-star-5 review-rating', 'review_body': "These seem great so far, after my limited use. A/C & heater seem way quieter, like it's not working so hard to heat & deliver warm air throuhout the house. This has a higher Meerv rating than the cheapies I've used before, with frequent changing. I'll probably continue 'earlier than called for' changing, even at the more expensive cost of these, because I'm the nervous type. So far so good, I just wish they weren't so expensive, but what isn't in the post-Covid apocalypse?"}, {'review_meta': 'Reviewed in the United States on November 23, 2020', 'review_star': 'a-icon a-icon-star a-star-5 review-rating', 'review_body': 'Buy cheap pleated filters and change them often. Way better than expensive thick filters that strain your HVAC. Ask your repairman. He will tell you the same. Cheap and often beats expensive and seldom.'}, {'review_meta': 'Reviewed in the United States on June 1, 2022', 'review_star': 'a-icon a-icon-star a-star-5 review-rating', 'review_body': 'These filters were recommended by my heating/air conditioning maintenance company and they get the job done. I have been satisfied so far as I’ve used them a couple of months. They fit snugly so was a little struggle to slide them in the slots.'}, {'review_meta': 'Reviewed in the United States on November 6, 2018', 'review_star': 'a-icon a-icon-star a-star-1 review-rating', 'review_body': 'Avoid this brand! To save cost I imagine, they undersized them to 19 3/8". Yes, I know 20"x20" are actually 19.5", but these don\'t even measure that - see my photos for proof. I KNEW SOMETHING WAS WRONG WHEN THEY FELL OUT INSTEAD OF STICKING SNUG IN THE SPACE.\nThe previous filters would stick in place because it was a tight fit, these fall right out because they are too small. Now I have to waste my time returning them. Aerostar should pay for my wasted time. The AirX Allergy brand I replaced them with fit right in, snugly, without me having to hold it up while closing the vent. The real problem is not that though, it\'s that air could go around this gap and totally bypass the filter. Make a good product that meets your description (19.5" x 19.5"), or don\'t sell on Amazon, you are wasting everyone\'s time.'}, {'review_meta': 'Reviewed in the United States on January 30, 2021', 'review_star': 'a-icon a-icon-star a-star-5 review-rating', 'review_body': "I bought these on-line because I did not want to venture into the hardware store during these times of Covid. They are the exact same size as my Ace Hardware filters and standard for the industry. Other reviewers complained that they were slightly less than 14 x 20, but this is the rule of the industry. Exact 14 x 20's wouldn't fit in most applications. Anyway, they are sturdy and well-constructed, and they allow greater airflow through my system, as is evidenced by nearly closed doors suddenly closing, sometime slamming, on their own when my furnace first comes on. This phenomenon is much more pronounced with these than with the Ace units I was using, This is a good thing. The price was very competitive through Amazon. Highly recommended."}]
