Breathe Naturally Universal Cut To Fit Carbon Activated Air Filter - Replacement Charcoal Filters - Pre Filter Carbon

These a very thick and durable. Easy to cut and fit into my AC unit. I also used them to line my cat’s litter box and I believe it did help a lot with the smell and dust that leaves the box. You also get so much in the pack. Great product! Read more

This filter does exactly what it promises and doesn’t try to be anything fancy about it and honestly, that’s a win. It’s easy to cut to size, fits perfectly in my portable and window air conditioners, and installs without any drama. I use these mainly to help catch dust, pet hair, and general household “mystery particles,” and they’ve been doing a solid job. Airflow hasn’t been noticeably restricted, and the added carbon layer is a nice bonus for improving overall air quality. Nothing complicated here: cut it, install it, forget about it. If you want a no-nonsense filter that works and is easy to customize, this one gets the job done. Read more

I use it in the kitchen, intake-air vent, to absorb odors. Mounted over a basic filter. Looks like it will work. My 10x48 Pre-filter Carbon Sheet is both made and packaged well. If this works in the vent, I will cut a smaller piece to fit the microwave filter. Read more

Carbon fibre pre-filters do a great job of minimising odours and catching material allowing your expensive HEPA filter to last longer by filtering out ultra small particulate matter. Without a pre-filter it clogged up very fast so this saves you money in the long run and it’s easily washable. Read more

I have an LG high efficiency window A/C. It has a washable filter over the evaporator coils and an electronic reminder to tell us when the filter should be cleaned. All well and good, EXCEPT that the filter is thin and cheaply made. It doesn't prevent a fairly rapid buildup of gunk on the internal evaporator coil, the fan, and the internal ductwork. Once all those components have a layer of dust and gunk all over them, the heat exchange suffers from the insular properties of the crud on the coils and the airflow is further reduced by the build-up on the fan. In short, the efficiency I paid extra for is lost until the unit is uninstalled, deep cleaned and put back in the window. What a pain! Breathe Naturally cut-to-fit filter material and some adhesive Velcro strips solved the problem almost completely. I put the Velcro "hook" half of the adhesive Velcro kit around the perimeter of the evaporator coil intake and some more around the two side and one bottom air intake vents molded into the case. (Search Amazon for adhesive velcro and you'll find what you need.) Then I installed Breathe Naturally filter material over all of these places - using the velcro to hold the Breathe Naturally material in place and make a good seal around the edges. The 1st set of Breathe Naturally filters over the intake vents pre-filter the air. The 2nd filter over the condenser coil inside the hinged front cover provide a secondary filtration stage. Lastly, the A/C's flimsy little factory filter - sitting between the cut-to-fit filter and the condenser - gets a third chance to stop particulates. In addition, the carbon in the Breathe Naturally filter material also does a great job of keeping the air coming out of the A/C smelling fresh and clean. I replace the Breathe Naturally materials about once every three months - and vacuum the surface dust off of them each time the "clean the built in filter" reminder light comes on. I also wash the factory filter at that time. I really love the performance and lack of odor and have yet to notice any visible buildup of crud on the A/C internals. Now I always have the high efficiency performance I paid extra for! All you need for this project is a measuring tape or ruler and a pair of scissors. A very easy and very effective DIY enhancement!
