Article Purpose
Learn what the four layers of the Healthful Plus Activated Carbon 4-Layer Face Masks consists of and their purpose.
Covered in this guide:
Soft, Non-Irritant Inner Layer
This white, extra soft non-woven polypropylene inner layer has been designed to reduce skin irritation and increase comfort. Attached to this layer are high-stretch elastic ear loops and adjustable nose bridge, providing premium comfort for all-day wear.
Hypoallergenic Filter Layer
Created using the melt blown process to protect the bacterial barrier and filtration efficiency of the mask, this filter layer is proven to block allergens and pollutants such as micro-dust, pollen, smoke, and other micro-particles from the air.
Activated Carbon Filter Layer
The main feature of this mask is the addition of a second filter layer made from activated carbon. Often found in air and water filtration, activated carbon (sometimes referred to as activated charcoal) efficiently filters unpleasant odors, pollutants, and volatile organic compounds (VOCs) from the air by trapping gas molecules and removing them from circulation.
Water-Resistant Outer Layer
The grey-textured outside-facing layer of the mask is made of non-woven polypropylene material like the first layer, designed to be leak-proof and resistant against airborne droplets.
Additional Information
What is the ‘melt blown process’?
Melt blown extrusion is a manufacturing process that is used for creating ‘non-woven fabric’ which is made from polymers such as polypropylene.
What is ‘non-woven’ fabric?
Non-woven fabrics do not involve joining yarn by weaving or knitting; instead, they mechanically, thermally, or chemically bound together material created from separate fibers of molten polymers forming a web-like fabric. The resulting fabric contains desirable properties that include but aren’t limited to:
- bacterial barrier
- filtering
- flame retardancy
- liquid repellency
- resilience
- softness
- cushioning
- sterility
- strength
- stretch
