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

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!

Love these and how convenient they are instead of going to the store to purchase.

These are perfect. Been using these for 15 years. Best price is on Amazon.

Whats more important than air? Some might argue... water. Well, those are the folks that like to argue the most. Some may say that water wouldnt exist without air, and those folks are called scientists. I was looking for a solution to filter the smell of air biscuits from our home. Our family is somewhat gassy. Luckily Amazon came to the rescue with these fart filters that you can jam into the slot of your central air unit. The only challenge was to pry the filters from within the cardboard fortress in which they have been imprisoned. And here Amazon is missing a mammoth opportunity to include a chainsaw as an add-on item. The carboard was excessively glued shut. Once I was able to open one side of the box with only minor injuries, the use of the filters is pretty straight forward. I would recommend taking the existing filter out of the AC unit first... but you do you. Almost instantly, we were all breathing fresh, filtered and unflavored air. Thank you Amazon for sifting the stench out of our lives.

Great filters killer price!!

They were super easy to put in the hvac vent. Seem to be doing a good job with filtering.

Ive noticed a huge difference! The dust in my home is almost non existing now! My breathing and indoor allergies are so much better! Worth the few extra bucks!

I wish these came in a 2 or 3 pack instead of 6 so I didnt have to spend $110 at a time and then store them somewhere for 1.5 years hoping they dont get dirty since the are all in 1 plastic wrapper

Easy to use, Well rated easy to install. My HVAC guys and the folks at ACE said this is the perfect combo between great filtration and performance but remember you have to replace more often because these filter more and get clogged faster. I replace ours once per month (1400 sq feet)

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