The durable pelletized design provides excellent airflow, outstanding adsorption capacity, and minimal dust generation, making it an ideal filtration media for residential, commercial, hobby, and industrial applications.The uniform 4mm pellets promote consistent airflow while helping adsorb odors and many airborne compounds in a wide variety of filtration systems. This versatile activated carbon is an excellent choice for air purifiers, grow room ventilation, hydroponic systems, 3D printer enclosures, laser engravers, workshop air cleaners, RVs, boats, garbage can deodorizing, compost odor control, pet odor filtration, and custom DIY air filtration projects. The durable pellet format also makes filter refills cleaner and easier to handle than many loose granular carbons.Whether you're replacing carbon media in an existing filter or building a custom air filtration system, EnviroSupply's premium pellet activated carbon delivers reliable long-lasting performance. Suitable for carbon filter housings, air scrubbers, odor control systems, ventilation equipment, manufacturing facilities, workshops, laboratories, and other vapor-phase filtration applications where dependable airflow and odor adsorption are essential. Review: Great Carbon Replacement for Air Purifier - I have two different HEPA air purifiers and one of them uses the same pellet style carbon in its carbon filter stage as these 4mm pellets so I bought the 5lb bag to use as a replacement. In addition to the HEPA filter and mesh screen pre-filter, my air purifier has a honeycomb pattern filter filled with carbon pellets throughout. There is a fine mesh screen on both sides of the filter to keep the pellets in place so I took off one side, emptied the old carbon, and then filled it with these new pellets. I bought a roll of fiberglass window screen from my local orange/white home repair store and cut it to the size of the filter to replace the mesh screen I took off. These pellets are a perfect fit and do an excellent job at getting rid of odors. We run our purifiers 24/7 to get rid of dust, dander, and cooking/pet odors (we have a dog) and I can say that it continues to do so with these new pellets as these work very well. One of the issues with carbon filters that I noticed with the air purifiers we have is that they tend to not last as long as the manufacturer says they should. Although in my experience, when compared to the sheet style of activated carbon, this pellet style of carbon seems to last much longer and gets rid of odors a lot quicker than the sheet style. Buying these replacement carbon pellets allows me to change the carbon without having to buy a new set of filters (the filters only come together as a set). Overall, these pellets are a great quality replacement and I can easily recommend them.
