PM2.5 refers to atmospheric particulate matter (PM) that have a diameter of fewer than 2.5 micrometers, which is about 3% the diameter of a human hair. Commonly written as PM2.5, particles in this category are so small that they can only be detected with an electron microscope.
Using a filter provides significantly more protection than a cloth mask alone, but with less inhalation resistance and corresponding heart strain than a professional respirator.
It is suggested that you replace the filters after every week of use. Protect your mouth and face from gases, noxious smells, pollen, smoke, dust, and other harmful particles floating in the air.
What goes in to a PM2.5 filter?
We take great care to ensure the filters are made of the highest-quality materials available. We require each filter to meet these standards:
Melt-blown Fabric
Composition by Weight: 40%
Characteristics: High quality melt-blown fabric is the most important part of a particulate filter. Non-woven fibers act as a physical barrier against microscopic particulates while also providing an electrostatic barrier to stop aerosolised nano-particles.
Spun-bond Fabric
Composition by Weight: 40%
Characteristics: Spun-bond is a non-woven fabric that filters out larger particles, while providing structure to the inner melt-blown layers.
Activated Carbon Fabric
Composition by Weight: 20%
Characteristics: Activated carbon fabric traps particulates via a process called adsorption, and also serves as an antibacterial and deodoriser.
