I ordered these for the first time in 16x20x1 in a 4 pack.Cons: I was surprised they weren’t individually wrapped in plastic.Pros: These are “cheap” filters, but that’s exactly what I wanted. If i order allergen rated high filtration filters, my old furnace just overheats and shuts off due to air flow restriction. These seem good so far.Sizing:The biggest complaint I saw from others on these filters is that they’re not a literal size. Meaning a 16x20x1 filter isn’t LITERALLY 16 inches x 20 inches x 1 inch.I replaced a 16x20x1 from another brand with this. It was the same size as the other 6 companies I bought from. They’re all the same (correct) size. Granted I haven’t ordered every size this company makes, but what I ordered was the size that I expected, and the same size you’d get from every other brand.Basically, the people complaining that they’re not the right size probably have no idea what size their furnace needs. Look at the older filter label, order that size. Job done.

We’ve always bought premium filters for our furnace as I have both COPD & Emphysema, but these are exceptional! Noticed a difference immediately in indoor air quality. Loved the pack of 6 filters which last up to 3 months each depending on how dirty your vents are. Will def purchase again!

In rental home or I’d have AC company make a permanent frame and buy the refills. Much cheaper.These disposals are ok found as warehouse deal. Still expensive. AC companies are better, significantly cheaper, and buy the refill you want for pollutants want filter to catch.

My nexrtdoor neighbor, who works part time in the heating and air conditioning business recommended a simple flat filter to me when I replaced one recently. I took his advice and purchased non-pleated filters and they’re working great. For the first time ever my electric company reported o my last bill my usage was less then its ever been ever for that particular billing cycle. I returned the pleated ones for a refund and will continue to uses single layer ones.

I bought the wrong size… Grrrrrr! But I found a way to improvise so it can fit.

Slightly bigger. Very difficult to slide into place.

These work great. Not super thick so the furnace can still breath good.
