Why should I buy and use these?
- Made of high-quality mesh, these filters effectively work well against oil-based pollutants as well as bacteria and viruses.
- These can help filter up to 99% of the particulate matter 2.5 from the air.
- These provide very soft and comfortable feel when worn under protective masks, disposable masks, and even ordinary civil masks.
- It’s highly recommended to buy bulk as these are only meant to serve their purpose for a limited amount of time, usually up to 40 hours or lesser depending on how fast each filter gets clogged.
