Basic Principle of HEPA Filter
The working principle of Air Purifier Hepa Filter is based on its special fiber material and design, which can capture and block tiny particles in the air. Traditional HEPA filters can effectively capture particles with a diameter of 0.3 microns, which is also widely recognized as the difficult particle size to capture. Therefore, when Air Purifier Hepa Filter promises 99.95% filtration efficiency, it means that it can remove almost all 0.3 micron particles when air flows through the filter.
Applicable particles

Dust particles
Features: Dust is one of the common particles in the air, mainly composed of soil, sand and fine plant particles. The diameter of dust particles is usually between a few microns and tens of microns. Air Purifier Hepa Filter can effectively capture these particles and reduce the impact of dust on indoor air quality. It is particularly suitable for areas with frequent wind and sand.

Pollen
Features: Pollen is a tiny particle released during plant reproduction, with a diameter generally between 10 and 100 microns. Pollen is one of the main allergens that cause allergic reactions. Air Purifier Hepa Filter can effectively remove these particles and help reduce seasonal allergy symptoms.

Dust mites
Features: Dust mites are tiny insects that mainly parasitize mattresses, pillows, carpets, etc. Although dust mites themselves are small in size, their excrement and dead particles float in the air and easily trigger allergic reactions. Air Purifier Hepa Filter can effectively capture these fine particles and reduce the harm of dust mites to health.

Pet dander
Features: Pet dander is the skin fragments shed by pets, which usually contain various allergens. Dander particles are usually between 1 and 10 microns. Air Purifier Hepa Filter can effectively remove these fine particles to ensure that the living environment of pet allergy sufferers is cleaner and more comfortable.

Harmful chemicals
Features: In modern living environments, various harmful chemicals, such as volatile organic compounds (VOCs), are often present in the air. Although HEPA filters are mainly targeted at particulate matter, their high-efficiency filtering capabilities also help reduce the concentration of these harmful substances, thereby indirectly improving air quality.

Application scenarios of HEPA filters

Air Purifier Hepa Filter is widely used in home, office and industrial environments. In the home, it can effectively improve air quality, especially in environments with allergies, pets or high dust. In office environments, HEPA filters can help reduce employee health problems caused by air quality problems and improve work efficiency. In the medical and industrial fields, the high-efficiency performance of HEPA filters is a key factor in ensuring clean air, such as in pharmaceutical factories and laboratories.
