1.Specialized filter for the paint area in art studios, designed to absorb the smell of oil paints and turpentine. The activated carbon layer adsorbs the smell of organic solvents, while the HEPA layer filters out paint dust and brush debris. The filter is resistant to organic solvent corrosion and is compatible with the air purifier in the paint area. Continuous purification can reduce the irritation of paint smell to painters.

2. Medical-grade antibacterial HEPA filter, with a silver ion antibacterial coating, effectively inhibits the growth of bacteria such as Escherichia coli and Staphylococcus aureus, preventing the filter from becoming a secondary pollution source. The activated carbon layer uses coconut shell activated carbon, with rich pore diameters and fast adsorption speed, quickly decomposing kitchen fumes and pet odors. The filter thickness reaches 30mm, with a filtration area 40% larger than ordinary filters, and low air resistance does not affect the air purifier's output. It is compatible with multiple wall-mounted new air machines and needs to be replaced every six months, reducing maintenance costs.

3.High-efficiency filter for fresh air systems, featuring an H13 HEPA layer and a thick activated carbon layer, suitable for ducted fresh air systems. It can filter outdoor smog, pollen, and vehicle exhaust particles, while adsorbing formaldehyde and TVOC. The filter is wrapped with a sealed sponge around the edges to perfectly fit the fresh air unit and prevent unfiltered outdoor air from seeping in. With 120 layers of folding, it has a large filtration area and low air resistance, ensuring the fresh air flow is not affected and providing the entire house with continuous clean fresh air, making it a safer alternative to opening windows for ventilation.

4.Specialized filter for nursing home cafeterias, designed to handle kitchen odors and food smells. The activated carbon layer is infused with natural fruit and vegetable extracts, removing odors while releasing a light fragrance. The HEPA layer filters out kitchen dust and food debris. The filter is heat-resistant and corrosion-resistant, suitable for wall-mounted purifiers in cafeterias. Continuous operation can improve air quality in the cafeteria and reduce the irritation of kitchen odors to the elderly.
