USA-Made Face Mask Filters
Our face mask filters are HEPA-11 filters, made in the USA from high quality H11 grade materials. HEPA-11 filters have a filter rating of 99.97 filtration @0.3 microns which gives 95% filter rating. This is equivalent to an N95 medical mask and is far superior protection to Chinese made PM2.5 filters which offer 50% filter rating.
The mask filter dimensions are 5″ x 4″ and easily slide in to any of our custom masks. These filters are fibreglass free, breathable, ultra-soft and easy to insert.
High performance filtration media – Melt Blowing
Melt Blown nonwovens are nonwoven production methods in which high content thermoplastic polymers such as PP (polypropylene) are melted and extruded through a nozzle. In the case of complex spinning, two types of high polymer resins are used to transfer the high polymer melt to the dosing pump through the extruder, distribution valve and nozzle. This is a nonwoven production process in which high temperature air at high pressure is introduced into the molten polymer during spinning and then laminated, while a specialized conveyor belt combines with the self-adhesive properties of the residual heat in the form of a nonwoven fabric.
High performance filter material, air filter
It has excellent tensile strength, tensile strength and impact resistance, producing man-friendly and highly flexible urethane materials in a non-woven fabric through the fusion process.
In addition, it can be used continuously for a long period of time, as it has excellent rebound resistance and recovery elasticity. This elastic non-woven fabric is more environmentally friendly and safer for humans than PVC materials. It is made of fabric materials and has excellent breathability, which provides a feeling of freshness to its users without irritating the skin.
