What is PM 2.5 filters?
PM 2.5 filters are a special type of high-purity polytetrafluoroethylene (PTFE) membrane filter designed to capture micro-particulates which are present in the air from dust to pollen to viruses, so it is best to choose a filter with a PM2.5 rating.
How do PM2.5 Filter’s work?
A good quality PM2.5 activated carbon filter is equipped with five layers. Encased in non-woven fabric are the melt-blown cotton and activated carbon sheets.
Creating a barrier that captures the microscopic particles. The melt-blown material in the pm2.5 filter provides a superior filtration and absorbs the particles which should filter out most viruses.
This depends on the level of usage, the ambient levels of pollution, hygiene levels, and the environment where the mask is used. We recommend that you replace the filter once per day.
