Chris: I used to buy these a lot for about $8.00 CAD. Good product. Then they went up to $40 but now down to about $20. Now I buy alternatives that are washable.

Ed CEd C: Picture says 1000 words, see the picture attached. This was after about 2 months of the filter being in the AC, next to a freshly cut piece to replace it. Generally they will last much longer but I live on a main road, and a lot of dirt is kicked up by passing cars which contributes to the filter becoming so dark and needing a replacement quickly. It also does a good job filtering the occasional smoke(from cooking or other). These things certainly do a good job filtering the air cycling through window AC units. I cut it to size and attach it to the plastic filter found in the unit with some tape. I dont recommend wrapping it so the filter covers both sides, I did that at first and it significantly disrupts the ability for the AC to cycle air and can hurt the motor long term/cause it to lock/freeze up. But even with the filter only on one side it does a great job. Previously we only used an air purifier, but with these in addition to the purifier I feel confident the air circulating in my apartment is NOW much cleaner.

I got these filters to put into the 2 Window AC units I have in my apartment for the upcoming season. I live in NJ and put the window AC units in about 2-3...

J. S.: These are great. I first purchased them when I was living in Saudi Arabia and the industrial-grade HVAC in my villa had no exit filter, so it blew all the dust, dirt, and who knows what else into all my rooms. My allergies were going crazy and I had constant congestion. I found these here on Amazon, bought like 12 packs of them and installed them over all the outlet vents throughout my villa. I noticed a difference almost immediately. No more dust and dirt floating around in the air or landing in my dogs water dish and my allergies substantially improved (no more waking up with sinus congestion and bags under my eyes). I had to replace them every 6-8 months (I should have probably been changing them more often), but they held up the entire time with no holes or leaks at all, and I really only changed them because I could see the interior side looked like it was getting absolutely filthy. When I pulled the filter sheet off to replace them, the inside was basically black with all the cr*p my HVAC system and ducts were blowing into my villa, it was disgusting. So, needless to say, in this extreme environment, these filter sheets really did an amazing job at keeping my air clean. I...

C.zs: Great product for filtering small particles. But I think I have overpaid for this. Heard they sell them in rolls in hotter countries for the air con.

Client d'Amazon: remplacement de filtre sur bionaire 1000

Canada on Apr 22, 2019

Run: I use a Holmes purifier unit for my room due to allergies and dust. My bedroom window is at ground level, so my room tends to get more dust than usual when left open. I got tired of spending 15$ on filters that were supposed to fit the unit, but never created a good seal due to poor quality control and design. So, I figured...how hard would it be to make my own. Well, it was pretty darn easy. I purchased a cut to fit foam pre-filter. I purchased this Filtrete cut to fit filter. Placed the Filtrete on top of the foam, cut both to appropriate size, and simply places thinly cut strips of duck tape around the edges, and stuck it in the intake vent. It works a lot better than the expensive filters. It was much cheaper because due to the large sheets of cut to fit, I have enough for just about a year, if changed every couple months as per instructions. I only gave this 4 stars because there are some areas on the Filtrete that are "thinner", as in not containing as much filter material woven in. So some small portions will be tossed out for that reason. 8$ for this Filtrete, 1$ at walmart for the foam pre-filter. So for 9$ plus some duck tape I had sitting around, I have replacements for...

Etienne Voyer: Très pratique

Lynn in PA: These might be intended for use with air conditioners, but I use them to cover the intake air vents on my forced air heating system. One intake is just about the size of the filter so I keep it in place with two, small magnets at the top. Yes, I have a regular filter in the furnace itself, but using this, too, has made a BIG difference in the quality of the air. One can visually see when it is time to replace it with a new one.

I am glad Amazon now carries them, because my local hardware store does not normally stock them in the winter. They might now that I told them they work great on forced hot air intake ducts, but they are out of stock right now so I am just ordering them here (at about the same price).

If one's duct work is not that clean, this can also be cut to size to put inside the air output ducts. This is a lot of work, though.
