Our 5 layer PM2.5 filters provide both mechanical and electrostatic barriers, capable of blocking small nanoparticles. Waterproof, breathable and cost-effective, these filters are great to pair with your reusable masks if you want added protection.
Spunbond is a non-woven fabric that filters out larger particles, while providing structure and holding the finer non-woven layers in place. Two layers per filter.
This advanced material has electrostatic properties that help it capture microscopic particulates as they attempt to pass through. Two layers per filter.
This material traps particulates via a process called adsorption, and also serves as a natural de-odorizer and has anti-bacterial properties. One layer in every filter.
*All good quality pm2.5 filters should have 5 layers in total and 2 layers of meltblown fabric. Watch out for companies that sell fake filters with 4 layers instead of 5, and have 1 or less layers of meltblown fabric.
- Recommended usage period: 16-24hrs (around 1 week of occasional use)
