Thin By Design
Activated carbon has been treated with oxygen to create thousands of tiny pores between the carbon atoms. This creates a highly porous material that has a large surface area, making it ideal for adsorbing impurities and pollutants in the air. When air passes through the pre-filter, the activated carbon traps larger particles like dust, pet hair, and lint while still allowing for maximum air flow. It also absorbs and reduces odors and volatile organic compounds (VOCs) like smoke, cooking smells, and chemicals.
Expanded Compatibility
Widely compatible and versatile filters are ideal for use in air purifiers, vents, fans, windows, trash cans, litter boxes, range hoods, furnaces, HVAC systems, dehumidifiers, and more. The customizable design ensures no gaps for unfiltered air, enhancing the efficiency of your device. Our carbon fiber filters trap lint, dust, and VOCs to provide fresh, breathable air.

These versatile and easy-to-use universal cut-to-fit filters come in 16” x 48” carbon fiber sheets so you can create replacement filters on-demand for an array of appliances. Keep your home outfitted with filters for HEPA air purifiers, range hoods, countertop compost pails, covered litter boxes, and even nursery grow tents. Our carbon filters can be tailored with scissors and a ruler or template to fit your space and keep your home free of pet odors, cigarette smoke, chemical smells, and more.
Cost-Effective Solution
Making your own low-cost replacement filters is a great way to give your budget more breathing room. Cut-to-fit filter pads are not only cheaper than pre-cut filters they’re easier to use even when appliances become outdated. Keep your trusty HVAC unit, air purifier or range hood operating at peak performance with a universal replacement. Buy one product to replace filters for a variety of your appliances.
Eliminate Harsh Odors
Millions of micropores in our carbon filters trap lint, dust, dander and volatile organic compounds that irritate the eyes, nose, and throat. Activated charcoal helps neutralize odors and eliminate signs of cigarette smoke, cat litter boxes, and more, so you can welcome guests into your fresh-smelling home with confidence.

I purchased this to make replacement filters for my humidifier since there were no replacement filters available from the humidifier manufacturer. Works great for me and the material is an upgrade to the stock filter that came with the humidifier. An added plus is the material is suitable and better than the stock filter that came with my over the range microwave oven/vent system.

I used this in my septic pump closet in my basement. It definitely helped with odor control.

I like that you can cut squares as needed but you get what you pay for. Seems sparse compared to my precut squares. Hoping it is still doing the job.

You can just read the benefits of this type of filter. I like that this is easily adjustable. Meaning you can cut it in any size that you need. Seems like a great value for the price.

This filter is useless. The carbon filter stuff was all dried out and made a complete mess of black dust. Do not recommend at all!
