Aerostar 20x20x1 MERV 8 Pleated Air Filter, AC Furnace Air Filter, 6 Pack (Actual Size: 19 3/4′ x 19 3/4′ x 3/4′)

I was a little concerned about the difference in the listed size and the nominal size, but it fit just fine and was exactly the same dimensions as the one my hvac company put in when they were last here for service. This is a difficult, it not impossible, size of filter to find in a retail store. The last time i needed one i went to the hvac company that installed the unit and even they had to check the warehouse to make sure they had one in stock.
It doesn’t have any reinforcing cardboard on top (the air inflow side) but it seemed sturdy enough and not in danger of warping or collapsing.

These filters are great. The price is one of the best deals. I could find on amazon and elsewhere. The filters are solid, effective, and long lasting. My ac system is fairly clean and being in florida, it runs maybe half the time for most of the year. All i can say is that the air feels fresh and the condenser coil has stayed squeaky clean for 10 years.

It isn’t rocket science to get the right air filter, but just make sure when you take out your filter that you know 1.) what size is the filter, and 2.) which way the arrow for the air flow is pointing. Just two things to remember. I’ve noticed a difference in the air quality in my house after putting these in. Shocker. I’m sold and will keep using these in the future.

To fit in my mobile i just have to bend it a little in the middle and then it snaps right into place.

Odd size so hard to find in stores. Great price. Will be reordering.

Not much to say. These filters fit perfect.

I have tried a bunch of different filters. These seem to be better than the other cheap filters, but still cost less than the expensive ones. I think i will go with these from now on!

Product received and in good condition.

Great iguassu but i accidentally bought the wrong size

We just had our yearly hvac inspection and tune up. The tech examined and gave a thumbs up on these filters for use here in florida. That’s good enough for me!

These filters work well and are supposed to last more than a month, however i like to change mine out every 6 weeks or so. My only problem with them is that they are hard to pull out, as they become flimsy after use. This may be quite common with all air filters.

Good value for money a must have item to keep an expensive replacement of furnace air conditioning unit in top shape

Works in furnace. Not as allergy sensitive as some filters but great product for the price

Amazon lost my last order of hvac filters. These work great!

Air filters. Work as advertised.

Seems to work well, filters out the dust. When i replace the first one with the second if it is dirtier than the last box of filters came out then i guess a higher merv number was worth it.

They are a good air filter

These fit better than the more expensive ones i was using. They are a bit thinner so i am not certain how well they hold up. I just installed the 1st one today.

The filter is made well. No complaints there but while the size marked was what i needed, i had to cram and bend it to get it in the intake. Therefore not a good fit for the filtered air.
