How to judge whether the filtration effect of the electric purifier meets the requirements

  First, check whether the product has passed the relevant certification standards, such as N95, N100, etc. These certification standards are formulated by an authoritative body, and the certified products have a certain guarantee on the filtration effect.

Understand the filter materials used in the product, such as HEPA (High Efficiency Air Filter) and activated carbon. HEPA filters filter out most of the tiny particles, while activated carbon absorbs harmful gases and odors.

Check the filtration efficiency indicators of the product, such as the filtration capacity of PM2.5, PM10 and other particles, and the removal rate of specific harmful gases (such as formaldehyde, benzene, etc.). These indicators can directly reflect the filtering effect of the product.

Refer to other users' reviews and professional reviews to understand the filtering effect of the product in actual use. User reviews can provide a real experience, while professional reviews can provide more objective data analysis.

If possible, field tests can be carried out to observe the filtering effect of the product in different environments. For example, when used in hazy weather or smelly environment, observe whether the product can effectively filter pollutants and odors.

Check the tightness of the product to make sure there is no air leakage. Good sealing ensures maximum filtration effect.

Pay attention to the updating information of products and learn about the latest filtration technology and materials. New products often use more advanced filtration technology to provide better filtration results.

Through the above methods, you can have a more comprehensive understanding of whether the filtration effect of the electric purification respirator meets your needs. When selecting products, it is recommended to choose well-known brands and products that have passed authoritative certification to ensure the reliability of the filtering effect.
