What goes in to Puraka's carbon pm2.5 filters?

meltblownMeltblown Fabric

Composition by Weight: 40%

Characteristics: High quality meltblown fabric is the most important part of a particulate filter. Non-woven fibers act as a physical barrier against airborne micro-particulates while also providing an electrostatic barrier effective against fine aerosols in the sub-micron range.

spunbond Spunbond Fabric

Composition by Weight: 40%

Characteristics:Spunbond is a non-woven fabric that filters out larger particles, while providing structure to the inner meltblown layers.

Activated Carbon Activated Carbon Fabric

Composition by Weight: 20%

Characteristics: Activated carbon fabric traps particles via a process called adsorption, and also serves as an antibacterial and deodorizer.
