With the rapid increase in air pollution in cities and their surrounding areas, air purification is receiving increasing attention from people. To solve this problem, many companies have launched a series of powerful air purifiers that can effectively clean and purify the air in homes, offices, or other indoor environments. China’s air purifier factories are renowned for their innovative design and user-friendly features. In this article, we will discuss the common filters used in different types of air purifiers and provide some insightful conclusions.

There are many different classifications for air purifiers. The first type is classified according to different usage scenarios, including car, home, office, hotel, hospital, etc. Home air purifiers are designed for living spaces and provide powerful filtering capabilities for larger areas. Hospital air purifiers generally use medical grade filters. The second type, classified according to the size of air purifiers, includes desktop air purifiers and floor stand air purifiers. Due to different usage scenarios and sizes, the filters used in air purifiers also vary.

Air purifiers manufactured in China typically use a range of filters to remove different types of pollutants from the air. Some of the most common filters used in China air purifier factory products include:

Pre-filter: a type of filter that is used in air purifiers to capture large particles such as dust, hair, and pet dander. The pre-filter is typically the first stage of the air purification process, and its primary function is to prevent these large particles from clogging the other filters in the air purifier.

HEPA filter: HEPA filters are a type of air filter that are used in air purifiers to remove small particles from the air. The acronym “HEPA” stands for High Efficiency Particulate Air, and HEPA filters are designed to capture particles as small as 0.3 microns with an efficiency of 99.97%. HEPA filters are effective at removing a wide range of particles from the air, including: pollen, dust mites, pet dander, mold spores, bacteria and viruses.

Activated carbon filter: Activated carbon filters are used in air purifiers to remove gases, odors, and volatile organic compounds (VOCs) from the air. Activated carbon filters are made from carbon that has been treated with oxygen to open up millions of tiny pores between the carbon atoms.

Photocatalyst filter: Photocatalyst filters are a type of air filter that use a chemical reaction to remove pollutants from the air. They work by using a catalyst, typically titanium dioxide, to break down pollutants when exposed to light.

UV-C light: Some air purifiers use UV-C light to kill bacteria and viruses in the air. The light damages the DNA of these microorganisms, preventing them from reproducing.

Ionizer: An ionizer releases negatively charged ions into the air, which attach to positively charged pollutants such as dust and pollen. The particles become too heavy to remain in the air and fall to the ground, where they can be easily cleaned.

Overall, the combination of these filters and technologies can effectively remove a wide range of pollutants from the air, improving indoor air quality and promoting better health.
