Lingjie HEPA, the preferred choice for HEPA filters in air purifiers

Lingjie HEPA (High Efficiency Particle Air Filter), which means high-efficiency air filter in Chinese, is a filter that meets the standards of Lingjie HEPA. It has an effective rate of 99.7% for 0.1 microns and 0.3 microns. The characteristic of Lingjie HEPA is that air can pass through, but small particles cannot pass through.

It can achieve a removal efficiency of over 99.97% for particles with a diameter of 0.3 microns (1/200 of a hair diameter) or more, making it the most effective filter medium for pollutants such as smoke, dust, and bacteria.

Lingjie HEPA is divided into five materials: PP filter paper, glass fiber, composite PP PET filter paper, melt blown polyester non-woven fabric, and melt blown glass fiber. Features: Low wind resistance, large dust holding capacity, high filtration accuracy, can be processed into various sizes and shapes according to customer needs, suitable for different machine models.

Performance indicators:

Filter paper name filtration efficiency (%) air resistance (5.33cm/s) service life

Fiberglass>99.97 90pa 12-18 months

PP fiber>99.9 30-50pa 12-18 months

PP PET composite>99.9 20-40pa 12-18 months

Melt blown polyester non-woven fabric>99.97 20-40pa 12-18 months

Melt blown long fibers>99.7 20-30pa 12-18 months

At present, Lingjie HEPA is mainly used in household purifiers, household vacuum cleaners, and medical purifiers. With the widespread use of purification machines abroad, HEPA filters can be purchased in supermarkets. It is very common for purifiers to purify. Domestic brand machines are mainly occupied by foreign brands with a market share of about 20%, but the HEPA filters inside the purifiers are generally from China. Domestic brands such as MORAL, Yuanda, Midea, and Yadu also hold a significant market share in household appliances. The commonly used HEPA filters in the market are mainly folded from high-efficiency filter paper, which has a significant filtering effect. Lingjie HEPA filter is the preferred choice for purifier filters.

It is internationally recognized as an efficient filtering material. All clean engineering requires high-efficiency filters; A few years ago, there was a type of filter called sub high efficiency filter that was basically not put into use anymore. Widely used in high cleanliness places such as operating rooms, animal laboratories, crystal experiments, and aviation.
