Simply 20x20x1 Air Filter, Merv 13, 6 Pack, For Home AC Furnace & HVAC (Actual Size: 19.75"x19.75"x0.75") DUST, Pet, & Allergy Control

Performs great! Love MERV 13 and can’t beat the price

I bought these after using cheaper ones thinking they would work better. I know you’re supposed to change them regularly, but it was 30 days exactly before my ac stopped keeping up and I found out it’s because this was so filled up with dust. For about 3 months it did this before it wouldn’t fill up so fast. So I guess you could say it did its job well. The size was accurate and what I needed.

As good as I've found anywhere else and they were delivered by Amazon Prime free quickly. I just keep purchasing them.

These October 8th, 2025 20x30x1 MERV 13 filters are very, very bad. The filters don't fit. The material along the edges is very thin and flimsy. They don't look like the pictures shown when ordering. The construction, precision, and appearance are of the cheapest quality. I have a feeling they are counterfeit. "Simply filters" is printed on them, however. The logo says "simply filters," but the appearance of the logo is different. I have tried three of the 6-pack of the bad filters. All three were very bad. The filters collapse in on themselves when the air starts circulating. They don't seal along the edges because of this. Eventually, one of the filters collapsed so much that it was pulled up the vent into the ductwork. A filter like this could actually be a liability, potentially damaging the HVAC system. I have used plenty of MERV 13 filters before. These are very different... in a bad way. $58.15 was paid (after sales tax) for six filters. These filters are not worth anything close to that. They look like filters, but don't work.

I order these often and change out my filters every month. These are less expensive than most and do a really good job. No reason to pay more.

love the product...but dislike the packaging. The box arrive bent and therefore one of the air filters is totally unusable and the others though useable are not in perfect condition either

Great quality and fit. Noticeably less dust in home . Love the convenience of the multi pack

Work as expected

Fit is exactly as per sizing shown. Better filter than the Merv 8 we had been using as they seem to catch more dust. Will securely keep using .
