PM 2.5 Mask Filter (Pack of 10) is designed for PP reusable face masks and fits into the internal pocket for added protection compared with wearing a mask without a filter.
Each PM2.5 filter uses a five-layer structure with non-woven fabric, melt-blown cotton, and activated carbon sheets. The melt-blown material helps create a barrier that captures microscopic particles.
PM 2.5 filters are described as a high-purity polytetrafluoroethylene (PTFE) membrane filter designed to capture micro-particulates in the air, from dust and pollen to viruses. Replacement is recommended once per day depending on usage, pollution levels, hygiene, and environment.
