The Glasfloss Z-Line Series pleated filters offer improved performance for virtually every application. All Glasfloss Z-Line pleated filters feature fibers which do not absorb moisture and will not support microbial growth. The Glasfloss Z-Line Series MR-11 filters achieve a MERV 11 rating per the ANSI/ASHRAE 52.2 Test Standard. The Z-Line Series MR-11 pleat is available in many standard face dimensions in 1”, 2", 4", and 6” depths. Glasfloss Z-Line Series pleated filters incorporate media which is laminated to a galvanized metal that stabilizes the media during operation. The pleats are formed in a radial configuration to ensure proper dust-loading. The standard pleated cartridge is bonded into a two-piece heavy-duty beverage board diecut frame that creates a double-wall thickness around the filter and prevents air bypass. The die-cut grilles are internally bonded to the pleat apexes on the air-entry and air-exit sides to ensure maximum integrity and support during the life of the filter. Glasfloss Z-Line Series pleated filters are used in a broad range of installations, from pre-filters to primary filters for computer room units. Whether used as primary filters or as pre-filters in multi-stage systems, Glasfloss Z-Line Series pleated filters offer a solution for virtually every residential, commercial, and industrial HVAC application.

lots of stuff goes around the edges (and not through)
these are smaller than other filters i've bought of the same size. It took me quite a long time to figure it out really, but over time I noticed more and more dirt on the floor-- and especially around the vents closest to the furnace. switching back to another Merv11 and the problem started reversing

No frills, just good filtration.
This is the second case of these filters I've purchased in as many years and I'll keep coming back.Merv 11, if you google it, does a dynamite job of removing particulates from the air - down to the allergen and smoke level.I'd probably opt for a Merv 13 but at that point, you are beginning to make your system work harder and if it's not designed for that level of filtration, in my mind, you would start putting added wear and tear on it.No frills, just good filtration.I recommend them and will purchase them again.

16x20x1 Merv 11 Furnace Filter Pack (Qty 12)
Nice filters and well made. it took about 2 weeks to get the product because they are made to order. They appear to be much better quality than the local store filters though. I have used them for 2 months and have noticed a decrease in allergy related sneezing in my family. At about $5 each, they are much better priced than my local store. Merv 11 filters are normally about $12 each so these filters are a great deal.

Very Good Value for the Price!
When I decided to look around for a better furnace filter than the standard ones you'd find at places like Home Depot, I was kind of shocked at the very high prices being charged for the better filters. However, I still wanted to get a more efficient filter not only to remove the smaller dust particles, but to minimize the amount of pollen, etc. floating around. I chose the Glasfloss Industries filters not only because of the price but because of the high MERV rating these filters have. So in theory at least, these filters are capable of scrubbing very fine particles from the circulating air. I've given a 4 star rating only because I've had these filters Just a few weeks so I can't say for sure how effective they are. I did notice a significant difference in how the air moving thru my heating system sounded. This tells me that the circulating air was moving a little slower, which is good in that the filter seems to be doing it's job.

so good I bought a year supply
I bought one of these in a store last month. I change my filter monthly and couldn't believe the difference when I change my filter compared to other filters. This filter looked like it trapped every particle! I see less dust and felt these are so good i bought a year supply!

Change your filters the first of each month to help maximize the efficient operation of your furnace.
Good price on something you count on year round. Since most parts of the country are either heating or cooling the majority of the year, it makes sense to keep a supply on hand.
