Abstract: Hepa filter refers to a high-efficiency air filter, with an efficiency of 99.7% for 0.1 microns and 0.3 microns. When comparing hepa filters and activated carbon filters, which one is better? In fact, both have their own advantages and disadvantages. When choosing, you can choose according to the air environment of your city. What does the specific hepa filter mean and which one is better, hepa filter or activated carbon filter? Come with me to the article to take a look! 1. What does hepa filter mean?
HEPA (HighefficiencyparticulateairFilter), which means high-efficiency air filter in Chinese, is a filter that meets HEPA standards. The effective efficiency for 0.1 microns and 0.3 microns reaches 99.7%. HEPA Network The characteristic is that air can pass through, but small particles cannot.
It can remove more than 99.97% of particles with a diameter of 0.3 microns (1/200 of the diameter of a hair) and is the most effective filtering medium for pollutants such as smoke, dust and bacteria.
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: large wind resistance, large dust holding capacity, high filtration precision, can be processed into various sizes and shapes according to customer needs, and suitable for different models.
2. Which one is better, Hepa filter or activated carbon filter?
1. Activated carbon filter adds an activated carbon layer based on non-woven fiber and adds a layer of activated carbon filtration. . The advantage is that it can filter odor, smoke, pollen, etc.; the disadvantage is that the wind resistance is large, the air volume is small, and PM2.5 particle filtration is not effective.
2. The advantage of HEPA filter is that it can filter PM2.5. HEPA has a filtration efficiency of 99.97% for particles with a diameter of 0.3 microns. The disadvantage is that it is more expensive, has large wind resistance, small air volume, and is relatively expensive. high.
As for which one is better, Hepa filter or activated carbon filter, it is recommended to decide according to the air in your city. In places with good air, the most common one is fine. In places with high air difference and PM2.5, choose HEPA. For filters, focus on removing odors and choose activated carbon filters.
