In residential buildings, office buildings, shopping malls, hotels and other civil and commercial buildings, the HVAC system is the core equipment for maintaining indoor temperature and air quality. As the "lungs" of the HVAC system, filters directly determine the cleanliness of indoor air and human comfort. This HVAC filter is specially designed to improve indoor air quality. It has multiple functions such as impurity filtration, allergen removal and odor adsorption, creating a healthy and comfortable indoor environment for all kinds of buildings.
The product has established a comprehensive purification system for common indoor air pollutants. In terms of particulate matter filtration, high-efficiency HEPA filter materials are adopted, with a filtration accuracy of 0.3 microns. They can effectively intercept suspended particles such as dust, pollen, pet dander, and mold spores in the air, with a filtration efficiency exceeding 99%. Especially for the pollen allergy problem that occurs frequently in spring, the filter material has undergone special electrostatic treatment. Through the electrostatic adsorption effect, it enhances the capture ability of tiny pollen particles. Even the pollen of trees such as cypress and birch with diameters of only 1-5 microns can be efficiently filtered, significantly reducing the discomfort symptoms of people with allergies.

In terms of removing harmful gases and odors, the product is equipped with multiple layers of activated carbon filters. It uses high iodine value columnar activated carbon with a specific surface area of 1000-1200 square meters per gram, which has a strong adsorption capacity for indoor volatile organic compounds (VOCs) such as formaldehyde, benzene, toluene, and xylene. Meanwhile, special catalyst components are added to the activated carbon layer, which can decompose some of the adsorbed harmful gases such as formaldehyde into harmless water and carbon dioxide, avoiding secondary pollution problems when the activated carbon becomes saturated. For common indoor odors such as cooking oil fumes, pet smells, and musty odors, the filter material also adds deodorizing factors extracted from natural plants. Through chemical neutralization, the odor removal effect is further enhanced, making the indoor air fresher.
