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)

Just received and installed. It fit snuggly like the name brand ones

I dont know why these filters seem to cost a small fortune these days when bought individually but a 6 pack lasts me a year and keeps my Electric bill low while costing less than half what buying one filter 6 times would cost

The Aerostar MERV 8 Pleated Air Filters work great and at a great price. They provide the best level of filtering dust without slowing my air flow. I change them every 4-6 weeks depending on my system usage as specified by my unit installer.

great airflow and captures a lot of particles to include pollen.

I ordered these as furnace filters of the 20x25x4 variety have become way too expensive since the pandemic. They are now about 40USD for one, where they were about half that previously. After much research, I decided to go with the MERV8 stnadard instead of the MPR1000 (MERV11) since the furnace does not require it and the amount of dust collected means that I change filter between four and six times per year. Overall, these look very similar to the name brand ones. Though the cardboard frame seems a bit thinner, it seems to be strong enough so far. The paper and the wire seem about the same. When installing though, I discovered that the 4in thickness is about 1/2 thinner than the name brand ones, which may be an issue if your frame will not hold them in place. Please note that these arrived in a cardboard box with no wrapping inside.... just six bare filters in a cardboard box. If the box gets wet, these will be ruined. If you can get these delivered dry, they may work for your furnace air filter frame depending on the thickness adaptability. I am waiting to check them next month to see if they are getting darker from all of the dust which it the main issue for us. I will update this review if they are worse than expected, but they seem to be stable in our Aprilaire air intake frame. I am cautiously rating these four stars for now. As always, your mileage and preferences may vary...

Easy to find the correct size and cheaper than locally sourced. Works fine.

It serves its purpose well.

Works great for my infloor airflow. I was using ones that had a higher number and my airflow was not good. Air-conditioned specialist told me its better to go with a lower # and replace monthly. That seems to be working

they work...change them out every few months.
