Filtrete 12x12x1 Air Filter, MPR 1500, MERV 12, Healthy Living Ultra-Allergen 3-Month Pleated 1-Inch Air Filters, 4 Filters

use filtrete filters always.

My HVAC person specifically told me these filters need to be individually wrapped, and in the past they have come in a box of 6, all wrapped separately. Not so with the most recent. I change filters monthly and I want them to be as efficient as they can be. This is a game changer for me. Ill look for another brand that wraps the filters individually.

I like these a lot and in fact after my new HVAC system was installed the technician recommended Filtrete Filters BECAUSE THEY HAVE REALLY GOOD AIR FLOW !

filter was advertised as filtering smoke but it did not do so with our forest fires in Sept here in western Mt.

Great filters at cheap price. As these provide higher rate of filtration really important to change these out regularly to not tax your HVAC.

I needed to replace my furnace filter but didnt want to go out in the horrible winter weather. Ordered these and they are exactly as described. No complaints.

It does what it says which is to filter particles (especially those bearing viruses) out of the air.

Traps so much dust, I should replace them every 2 month

Im glad I did order replace air filter for my furnace to keep clean & thank you very much!

Spending money on filters isnt sexy. Spending money on filters that dont work is torture. Filtrete works, quality is unmatched. Im an adult who smoked 20 years ago and now I use a vapor pen when alone in my bedroom. As a perfectionist who wants 1st quality without paying 6X retail for OEM Filters - Filtrete is my champion. Tip for newbie fan or air purifier modd-ers, you could consider the 1000 rated filters with low air flow or a 2nd layer such as carbon - and so on. You can consider higher than 1500 with Filtrete such as the 1900-2800s - etc. But the under 1000 air filters dont catch vapor and the filters higher than 1500 magically tell the vapor to make a run for the border. The vapor (smoke) will magically bypass the intake of your do-it-yourself box fair air filter or more expensive modified room air purifiers and cling onto the exhaust port from the fan and do another lap or two around your room prior to any chance of going into the intake. Im not proud about the time Ive watched analyzing this! Plus if the filters are 1900 or higher - and restrictive to start by the time you have some vapor, smoke, cooking residue, etc. etc. get into them - they are going to lose efficiency faster than I lost my high school mile time. I am a perfectionist type of gadget guy - and I dont want my bedroom or its connected sitting room dusty and showing the signs of my bad evening habit. I have (2) air sensing type air purifiers (adjust their fan to air quality), (1) IQ Air+ (expensive) that I found the 12x12x1 Filtrete 1500s stack nicely into and one large 3M/Filtrete Room Purifier (they discontinued them unfortunately) and I have found tremendous success with ONLY Filtrete 1500 Series Filters, a heavy duty set of scissors and foil HVAC/Tape. I am fortunate enough to have (4) Carrier Infinity Central HVAC Systems (with Air Scrubbers) but even with my bad vaping habit these Filtrete 1500s make the air in my oversized master the hospital grade at all times. Their build quality with tight-packed Vs and the superior tin fencing on both sides helps us jimmy-riggers win too! Best product on market without question. **Do add a carbon layer in whatever format you like and provides value - such as cut it yourself - if youre trying to combat odors - such as cigars or real cigarettes - or worse like from kitchens, bathrooms or basements. I have had some success placing a thin, cut it myself layer of carbon lining on the exhaust side (clean air output) side of one or two of my units. Hope it helps!
