The Celrith cylindrical antibacterial and antiviral filter is a multi-layer HEPA filter designed to capture fine particles and reduce bacteria and viruses in air purifiers and similar equipment. It filters PM2.5, pollen, dust, pet dander, and cigarette smoke, and its antibacterial and antiviral coating targets influenza A virus, E. coli, and Staphylococcus aureus. It is intended for high-end car air purifiers, household and desktop air purifiers, and health-conscious appliances. Celrith manufactures it with a 360° pleated structure for high airflow and efficient purification.
Airborne contaminants are not just a comfort issue; they are a load on the entire system. Fine particles such as PM2.5, pollen, and cigarette smoke penetrate deep into the respiratory tract and also accumulate on heat exchangers, fans, and sensors. Microorganisms like bacteria, viruses, and dust mites add a biological burden that can affect health and produce odours. In vehicles, carpets and upholstery release dust and allergens, while in homes, pets and cooking add to the particle load. The result is reduced airflow, higher energy consumption, and shorter equipment life. A filter that only captures particles but does not address biological contaminants leaves part of the problem unsolved.
When a filter becomes loaded with particles, resistance rises and the fan must work harder to maintain airflow, which increases energy use and noise. In air purifiers, a clogged filter reduces the clean air delivery rate (CADR) and allows more particles to bypass or recirculate. In automotive cabins, a saturated filter can cause musty odours and fogging, and may contribute to HVAC system strain. Biological contaminants can multiply on the filter media if it is not treated, turning the filter into a source of contamination. Regular replacement and a filter designed to handle both particulate and biological loads are essential to keep systems running efficiently.
Celrith's cylindrical filter combines a high-density pleated HEPA layer with an antibacterial and antiviral treatment. The 360° design allows air to enter from all sides, maximising the effective filtration area and maintaining high airflow with lower pressure drop. The HEPA layer captures fine particles, while the treated media inhibits the growth and activity of bacteria and viruses on the filter surface. This dual action reduces the biological load on the equipment and helps prevent odours and re-contamination. In tests according to FZ/T01100-2008, the filter achieved a dust mite removal rate of up to 82.4%, verified by a national authoritative testing body. Celrith can customise the filter's outer diameter, inner diameter, height, and filtration efficiency to match specific device requirements.
