1. Specialized filter for seafood markets, designed to address seafood and water odors. The activated carbon layer is added with seafood odor adsorbents, quickly removing the fishy smell, and the HEPA layer filters out market dust and fish scale debris. The filter is moisture-resistant and anti-corrosive. It is compatible with air purifiers beside seafood market stalls, continuously improving the air quality of the stalls and reducing the fishy smell's irritation to stall owners and customers.

2.Upgraded composite filter structure, integrating pre-filter, HEPA filter and modified activated carbon layer. The pre-filter first filters out large particles such as hair and dust, extending the lifespan of the core filter. The HEPA layer precisely captures allergens, and the activated carbon layer is added with nano-mineral crystals, increasing the adsorption capacity of formaldehyde by 60% and removing odors. The filter edge is sealed with heat-melt technology to prevent tearing. The pre-filter layer can be washed and reused, which is more environmentally friendly. It is suitable for household and office air purifiers, and is easy to install, creating a clean breathing environment for families with babies and children.

Whole-house purification filter for large apartments, with an ultra-large folded area of 5 square meters, suitable for central purifiers in large apartments. The HEPA layer filters out particles throughout the house, while the activated carbon layer absorbs formaldehyde and odors. It has low air resistance and does not affect the air volume throughout the house. The filter lasts up to 6 months, with a low maintenance frequency, creating a clean air environment for large apartment families without the need for multiple purifiers. 

Specialized filter for animal breeding areas in zoos, designed to address the smell of animal feces and body odor. The activated carbon layer is enhanced with biological deodorizers to decompose odor molecules, and the HEPA layer filters out animal hair and dander. The filter is moisture-resistant and anti-corrosive, and is compatible with air purifiers in breeding areas. Continuous operation can improve the air quality in the breeding areas and protect the health of breeders.
