FILTR FURN GLS 14X14X1"

Product delivered and works as described. I needed a MERV1 air filter in this size to alleviate whistling sound in the hvac.

I have used similar style filters for years and these are harder to find now with the invention of pleated filters. The pleated filters are a little harder on older HVAC units and these were tech recommended. I am currently using these as return vent filters to keep the dust out of the return duct after being cleaned 8 years ago when my HVAC unit was replaced. I have checked the inside of the return air ducts about a year ago and there was no dust, filters work great! Will continue to order from this manufacturer (yearly expense), would love the price to come down but I guess we'll chalk that up to inflation..

Yes, it is just a basic, quality air filter for my HVAC system but these are the best price I've found for this particular size so I don't cry at the expense when I change them monthly. The were also the only ones I ordered that were packed adequately and not smashed up in shipping.The longer story: I just bought a house with an older, but very reliable HVAC system and asked my friend who owns an HVAC business for advice to make it last longer. He said these hi-flow fiberglass filters are the very best because they are cheap enough to change monthly and don't cause the system to work too hard unlike most Hepa filters with higher resistance. I took his advice. The filters are consistently only lightly dusty when I change them at the beginning of month, but I actually have less dust than when I used the other filters and the AC doesn't "seem" to work as hard (though I will admit that could just be the placebo affect).I like these and I'll buy them again.

Our HVAC technician recommended that we use fiberglass filters for our system. These filters are a good value and do the job well. Per our technician we change the filters every month.

First off, these will do an adequate job as furnace filters. If that's the only thing you care about, then these are a great budget option. The only things I noticed about these vs some other fiberglass filters I've found in local stores is that the fiberglass seems to be lower quality, and the cardboard frame is a little flimsier than average. The fiberglass strands seemed to fray during shipping, and I got a fiberglass splinter while taking them out of the box, so be careful while handling these! Also, a couple of the filters frames were crushed & falling apart at the glued corners, which is why I'm a little concerned about the flimsy frame. It does seem like re-gluing the corners will fix them up enough to be usable, so all 12 filters will be usable, but it'd be nice to not need to fix brand new filters.

They are the least expensive filters that I could buy. Have used them before without issues. You must always replace them at least every 60 days for best protection.

For some reason this type of filer is hard to find locally in the size I need. The price is good and they work great.

These filters are getting harder to find, they're trying to force us to use more expensive filters that are too dense for older HVAC systems. A bit pricey, but so's everything these days...
