Wholesale industrial Aluminium frame air filter high efficiency 95% heap air fitlration filter

1. Washable long-lasting filter. The pre-filter is made of electrostatic cotton material and can be washed over 50 times. The HEPA layer is made of PTFE-coated material, which is waterproof and oil-resistant, and the filtration efficiency does not decline after cleaning. The activated carbon layer is detachable for cost-effective replacement. It is suitable for household economy air purifiers and has an overall lifespan of up to 1 year, significantly reducing replacement costs. It is environmentally friendly and cost-effective, making it a good choice for families seeking high value for money.

2.Industrial-grade dust removal filter, made of polyester fiber + glass fiber composite material, resistant to high temperatures and humidity, suitable for factory workshops, laboratories and other environments with a lot of dust. The filtration efficiency for dust and fiber debris is over 95%. The filter frame is made of metal, resistant to pressure and deformation, and can be repeatedly washed and used, reducing long-term usage costs. Customized sizes are available, compatible with large industrial air purifiers, with low air resistance that does not affect equipment operation efficiency, effectively improving workshop air quality and reducing the harm of dust to workers' health.

3.A thickened HEPA filter designed for smoggy days, with a filtration grade of H14, achieving a PM2.5 filtration efficiency of 99.99%. Even in heavily polluted environments, it can quickly reduce indoor particle concentration. The activated carbon layer is mixed with molecular sieves, not only adsorbing formaldehyde but also locking harmful molecules to prevent secondary release. The filter adopts a folded design, with an unfolded area of 2.8㎡, and excellent ventilation. It is suitable for car and desktop small air purifiers, with a lightweight design that does not occupy space, creating a mobile "fresh cabin" for the car.

4.Equipped with an H13 grade HEPA high-efficiency filter layer, it can deeply intercept 99.97% of particles with a diameter of 0.3μm or larger, including PM2.5, pollen, pet dander and second-hand smoke residue. Combined with a high-density activated carbon layer, it can strongly adsorb formaldehyde, benzene and other harmful gases. The dual filtration structure achieves whole-house air purification. The food-grade ABS frame is impact-resistant and does not deform. The sealing strip is tightly attached to the body to prevent air leakage. It is compatible with mainstream brand air purifiers and has a long service life of 3 months, offering better cost performance than original filters.
