AF Cut-to-Fit Activated Carbon Filter Charcoal Air Filter Sheet 16"x48" for Air Purifiers CP-6005

For about $6, this is something every household can use. Instead of paying $35 for a carbon filter for an air purifier or HVAC, this works as an alternative. The carbon material looks well made and does not shake loose carbon flakes. The size is handy for making several ordinary household filters, e.g. an air purifier, car cabin filter, range hood filter, HVAC filter. The folded section of filter comes in a convenient ziploc bag for storage, and with a couple Velcro strips for attachment. At 1/4" inch thick this seems to fit nicely in a filter frame. If greater thickness is needed, cut two pieces and stack them on one another. For example, behind a HEPA filter in an air purifier, it fits right into the frame when cut to size or even behind the old one so you have two layers of carbon filtration, the old filter is mostly ineffective for odor but still filters some particulates. The new one filters out odors. The cool clean smell this leaves is noticeable. And the durability and ability to cut to size suggests several uses, even a fish aquarium filter. It even looks like it can be rinsed with a hose and re-used, not sure if this will work for odors but it still can filter particulates out. For value, quality and versatility, this is 5 of 5 stars.

I'm using this for filtering the intake and outputs for my house forced-air heating system and as a filtration with window fans and it really is wonderful. Cutting to size is easy, with household scissors. It does tend to "shed" a bit of the charcoal so be aware. I can cut it to fit the registers for the heating system and I use it in all the vents. It's amazing how much dust and such this traps before it gets into the system! And easy to clean with a vacuum. Same with the window fans. I put a piece on the outer side to filter what's drawn into the house and it does the job wonderfully. And in both, the heating system and the window fans, it doesn't interfere with the air-flow. A good purchase and I will buy more as needed.

We don't have central air or heating. We do have a hepa based air purifier in the house. Still, a way was needed to filter the air entering the house. That way you take the load off the rather expensive hepa filter, plus you breathe better air even if it hasn't hit the hepa filter yet. I ended up designing an inexpensive 4-part filter system that attaches to a window and pushes filtered air throughout the house. The system consists of a replacement screening material that filters out dust, pollen, etc. ( PollenTec¨ Clean Air Window Screen (21" x 10`) ), this carbon filter, a furnace filter ( 15x25x4 Exact MERV 15 AC Furnace Filters Qty 2 ), and a standard 20" fan ( Lasko #3720 20" Weather-Shield Performance Box Fan ). The idea here is that the PollenTec screen is the first line of defense, trapping dirt, dust, pollen, etc., before these particles even enter the house and hit the main filter. The carbon filter is attached to the furnace filter such that air flows through the carbon filter first, and then through the furnace filter. The Nordic Pure furnace filter I used is the closest thing I could find to a hepa filter. These furnace filters are rated by the size of the particles they trap, known as the MERV (Minimum Efficiency Reporting Value). My research showed that a MERV rating of 13 would be quite effective, but I found a MERV 15 filter on Amazon and that captures even more bad guys (the higher you go in MERV however, the more the fan has to work to pull the air through). Furnace filters don't trap gases though -such as the fumes from a campfire- so that's where the carbon filter comes in. The fan is the final piece of the puzzle, which is set in place so that it draws in outside air through the three filters. To begin, I removed the existing screen from the window the rig would be placed in and installed the PollenTec screening in its place. If you have ever replaced the screen on a window or screen door before you know what this entails. It's not too hard a job, and having one of those little rollers ( New York Wire 90611 2-Wheel Wood Handle Screen Tool ) that push the spline into the groove that holds the screen is a big help. I didn't have have such a tool handy so I used a mini screwdriver. But that's just me. I recommend you get the tool because either tools will fly or tears will flow if you get the new screen 90% installed and then slip with the screwdriver and tear a whole in your brand new screen (I of course have never experienced either reaction, but I hear its possible). Next I attached the carbon filter to the furnace filter. I just cut the carbon filter to the size of the boxed furnace filter and used masking tape to fasten it in place. Worked like a charm. I then placed the 2-piece filter setup against the window opening and taped it in place. You can get really fancy here about how you mount the filter to the opening, but I found that again, masking tape was adequate for my situation (see photo). You want to choose a furnace filter that best fits the opening, and then be prepared to use cardboard, rubber, or whatever to seal any gaps. Now you have to attach the fan to the filter. The particulars of the window chosen of course dictate how much effort is needed to do this. One method would be to tape the 2-piece filter assembly right to the fan, then insert the fan in the window. What you need to achieve is a fairly tight seal between the fan and the filter so that when the fan is on it pulls air exclusively from outside the building. Because of the hi MERV rating the fan MUST make a good seal to the furnace filter in order to suck air through it. The entire job took about three hours and cost well under $200. Compare that to having a professional solution installed. Did it work? Yes! The only modification from here is to hook up an AC rheostat to reduce the fan speed further, and thus the noise. My theory is that as long as you are getting air flow you are producing positive pressure at this point in the house, and thus forcing out old air through other openings.

Effective odor and particulate remover. For the price these are hard to beat and they are very effective at removing most airborne particulates. They will remove odor for a short while as well, In my environment (dogs, kids) they effectively remove odor for about 15-20 days, yet they will remove particulates for a good deal longer. I usually run these between six to eight weeks then change out. For the few dollars you will spend on these it is well worth having cleaner air to breath. Watching all the crap build up on the back of these is quite satisfying, and not to mention will also extend the life of all digital devices. These filters are not very restrictive at all and can be used or attached to almost anything that moves air, cut pieces to tape around the intakes of your PC, cut pieces to tape behind your fans and watch the crud build up! Well worth the money, better yet this is more like a priceless return on an investment; Better health and living environment, extended digital appliance life.

I purchased this to use in a Holmes air cleaner model HAP412BN and a Hamilton Beach TrueAir Compact Pet Air Purifier. It works great for both. It comes as a single large sheet and I cut it down to fit each air cleaner. It cuts easily with a pair of regular scissors. The quality is very good - it works just as well as the original equipment filters but at a small fraction of the cost. And I mean small fraction - this entire sheet costs about the same as a single brand name filter for my air cleaners, but I have enough to make about 20+ replacements. The material is about 1/4 inch thick and comes folded in a zip-lock plastic bag for storage. It also include velcro strips (although I don't use those for the Holmes or the Hamilton Beach). Highly recommend.

I recently bought a Frigidaire compact air-conditioner with a poorly constructed filter that allowed outside pollutants, dust, etc., to be blown inside. Thanks to others with the same problem, who posted a solution. I followed their advice and purchased an electro-static filter along with this Cut-to-Fit Carbon pad, then cut each to size. The Carbon Pad is easy to cut, doesn't shed and is thin enough to use with the electro-static filter to radically change the unit's performance. No more dust, odors or pollutants getting through, although the unit seems to be a bit louder and working harder. I did try the electro-static filter on its own, but it didn't filter the outside odors - smell of smoke from nearby wildfires and seriously strong paint/solvents from building construction. I was genuinely surprised that such a thin Carbon Pad would be so effective.

Cut these up to put on the bad of 20" box fans because we have extremely large dogs in the house on a small farm... Dog gas is a part of life no doubt when they run around eating odd things on a farm for sure. Just a fact of life. So we figured since the charcoal pads advertise themselves as helping to remove odors much like a charcoal filter in a fish tank we figured we would give it a go. Fail. They didn't do anything at all as far as smells, and dust. (Holes are too big to collect dust) However - it catches dog hair, and a lot of it!! The better half and I have had at least two 120+pound dogs in the house for more than 2 decades, and never noticed that their box fans (yes, they get their own fans- hence the dog fart clouds on attack at times) blow hair through them. Honestly we just never thought about it that much. Not one of lifes great mystery's that we have ever contemplated I guess. Hehehe! Anywho they do, and the filters catch a it! It does lessen how strong the fans blow (trying to suck air through the filters dampens the motors pull), but is a good exchange for us. Doesn't eliminate all dog hair, but when living with dogs of this size, and the fact that we enjoy a clean house - Anything that helps collect hair without effort - is a good thing. So there you go! We do want to stress that after seeing how it boughs down the fan motors - there's no way we are installing these on our HAVAC system. Nope, not doing it. All that being said we DO recommend them for cheap fans as pet hair collectors. They've been useless otherwise. 3 stars for the unexpected use! Will buy again for the dogs fans, and maybe in the chicken coop too next summer! Hope the review helped!

I had been looking for this type of product for some time. I got tired of purchasing the precut sheets for cat litter boxes. I can easily use scissors with this product cut it to fit myself. This will save me a lot of money. I can also use this to replace the plug-in wall mount filters with a fan we have to remove odors from the house. This costs money too. I comes as described and can easily be cut with scissors. Be sure to keep it in the zip lock bag it comes with otherwise it will absorb odors from the house, become saturated and no longer absorb the odors for the application that you purchased it for. I am very happy with this product. This product is great for picking up volatiles as that is what activated carbon works best for. It also is a very rough particulate filter. This doesn't replace a HEPA filter but does work to remove volatiles and things like pet hairs, etc. This is a great replacement for the carbon prefilters you pay an arm and leg for other products.

Used it for both the cooker hood filter and the living room air filter. Works well in both

It serves the purpose instead of expensive filters as a pre filter. Important point is to avoid wastage during cutting.

Un peu fin, mais de bonne qualité dans l'ensemble. Un excellente alternative à bon prix pour des filtres de remplacement

This is easy to cut to the shapes that I need. The price was good. I will buy again when when needed.

Does what it says, cut to size and it works fine.
