What buyers say about FilterBuy 20x25x4 Air Filter MERV 8, Pleated HVAC AC Furnace Filters
After talking to friends, we decided to try these filters because our electronic air filter wasn't doing a good job and we didn't want to spend a lot of money on it.
The price was my favorite, we could only find them in packs of 1 for the same price, and 2 for that price is great.
These are cheaper than a lot of other filters on the market, and seem to be superior quality.
It's been difficult to find this exact size, and we were happy to find 2 for the price.
It is a good product, but it is not a replacement for the Honeywell 20x25x4.

You should contact the vendor, I don't think so.
