16x48 Cut-to-Fit Activated Carbon Filter Sheet Multi-Use Charcoal Air Filter Pad for Air Purifiers, Air Conditioners, Air Vents, Furnace Filters and Trash Cans

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 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 bought this filter as an additional carbon filter for my Winix 5300. The 16" width was the perfect size so I only had to make one cut. The material looked about the same as originals that came with unit. Indeed one of the reasons for buying the 5300 was because it has extra space for additional filters to be added. Professional reviewers have found that with additional filter the 5300 is superior in air filtration to many machines costing two or three times as much. The product is easy to cut with scissors and fits easily into my machine. I don't understand why people complain about this product and price of filter combo for the 5300. Personally I do not mind paying $50 for combination of a hepa filter and 4 carbon filters. I then add this product as additional filter so I have two carbon filters and a heap filter. So for about $60 I have enough filters to last about one year. Thats assuming changing carbon filters every three months. All in all it seems like a bargain for clean filtered air for my asthmatic wife. I am very pleased with the result.

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.

First I bought a cheap non pleated AC filter so air flow would stay good and not over work the blowers!Cut to fit.Taped to filter.After a couple of hours my high dollar air cleaners went from orange to green on air quality.So I will sell them.No cooking odors and the air in my place smells and feels clean.I sleep better, no morning coughs from the pollen in the air and my family is happier.So instead of buying high priced filters which do not work and air cleaners I will buy this and cheap filters.Since I work on AC units I have installed in other homes with the same great results.I live in Phoenix with hot nasty air and this product is worth every dime.Please note before I installed I cleaned my coils and blower cages which a lot of people never do as I know as they pay me to do it.Do not install with a high merv pleated filter!

I bought it to cover the filters in a ShopVac (much lamented company that recently failed) filter unit that is ordinarily used to filter wood or other dust when a temporary system is needed. I thought I’d put the carbon filter sheets over the existing filters to see if they would help clear the air when cooking smoked up the place since I lack a range hood. Low and behold it worked. The house doesn’t look like I’ve got a barrel fire going with a few old tires. The material was easy to cut and fit. I had read some comments that the sheet was thin. I disagree. Some light can be seen through it but you certainly wouldn’t want to cover your windshield with it and go driving (if you happened to want to try absurd uses). In my case fitting it was simple since the filter it went around was a simple cylinder and there was enough to cover the intake end with a round piece. Good value.

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.

Good product, arrived on time

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