I searched eBay for the best filters. Many brand name filters appeared as did the ones here that I purchased. They fit in my furnace firmly and are well made, sturdy. I was pleased with the quality of the filters.
Filters Delivered LLC 20x25x1 Air Filter MERV 8 Z-Line Series Glassfloss The 20x25x1 measures 19.5 x 24.5 x 7/16 The filter contains a metal mesh on the leaving air side of the filter. The cardboard housing is very sturdy and glued together. The filter mesh is firmly against the wires mesh and no flopping is present. This Air Filter is by far the best MERV 8 Air Filter I have found on the market.
Fabulous 21x25x1” furnace filters for the price! I was afraid they would be a bit flimsy, or get damaged in shipment, but were packed well and they are very sturdy. I will purchase again.
These air filters are well made and high quality. They clean the air as advertised. The sizes are accurate and fit the AC unit correctly. Will reorder more of these when needed.
While my furnace owner's manual stated the filters were Merv 11 20x25x4 it turns out they are really 20x25x3 7/8. A real 4" will not fit in the opening. The filters I bought look excellent and would work if they were just 1/8" thinner. I'm not too happy with York Furnaces and York Media Air Cleaner.
Have not installed one yet but anticipate great performance. Filters are very sturdy and well made. The best looking bulk type of filters I have ever bought. If they perform as good as they appear I be buying all my filters here.
These filters were a great price and a great value. They were more affordable than other filters of the same size and Merv rating. I have used them for several months now and can’t tell that there’s any lack of quality. Great purchase at a great price.
I'm very well pleased with the quality of these filters. They feature a full-boxed frame rather than the one side boxed frame that some other filters have. That makes for a sturdier, less flimsy filter. The filters are nicely pleated and reenforced with wire.
This the second purchase made. Operations of our HVAC units has been optimal with little to no loss of air volume. I am not a certified HVAC specialist but I regularly perform maintenance and cleaning of seven units on the roof of a 55,000 sqft building. I would recommend these filters for commercial use.
