Very happy to buy these online with reliable Sams Club. I was going to use another online vendor but I saw that Sams Club sold them. These are the filters I have been using and the price was right.

These are a little pricey. I have used some "generic" one with a higher MERV rating with better results, but cannot always find those. These do work pretty well, but need changed more frequently.

Fit perfectly and aided tremendously in the process of removing mold from my mothers home. The ones made specifically for Honeywell weren't cutting it.

These are great furnace filters. My local big box stores were sold out so I ordered this twin pack. I have used Filtrete filters for a long time as I think they are the best.

Great product

Just wat I needed it

Buyers beware: The actual size of the 16x20x4 was reduced at some point last couple of years. As the result it doesn't properly fit in Honeywell / Lennox filter boxes, despite the advertisement on the packaging. The filter size used to be 15-7/8" x 19-7/8" x 4-5/16". The new filter size is 15-7/16" x 19-3/4" x 4-5/16", so it is 7/16" (1 cm) narrower than the old filter.

Usually we have no issues with these filters. They worked great in our HVAC system for years. Now with that said my last orders the filters are running smaller. There is a major Gap in with on all sides, I can hear my AC is whistling and I can slide my finger in between the framing, very disappointing. I am afraid to order these again. What’s going on? As you can see I have placed a folded newspaper on top edge and size edge to help it fit and not flop around while the fan is blowing. Hope this doesn’t harm my system. Not have the funds to purchase new ones at this time. My last order was 2 Box purchase a total of 4 filters.

Yay !! Delivery was earlier than expected.

Great product and filter for your money. I will definitely buy again
