What you need to know when buying your mask

During this pandemic, wearing a face mask become a habit for our everyday life, and we no longer leave the house without them. We all know wearing a face mask helps to protect us even not completely.

Nowadays, there are so many different type of Face Mask out there, while you're buying a face mask for protection, have you ever wondered effective they are?

The American Society of Testing and Materials (ASTM) is a global organization that develops and publishes technical standards for a wide range of products, which includes face masks

All tested and approved face masks recommended for use during this pandemic are usually three ply ones, consisting of three individual layers:

1. Outer layer A layer of non-woven fabric. This serves as a waterproof barrier that repels droplets and moisture expelled by people while talking, coughing, or sneezing. 2. Middle layer Acting as filter, this layer is usually created from polypropylene (PP) melt-blown non-woven fabric. It has electrostatic properties which helps to trap aerosolised particles via electrostatic attraction. An effective middle layer should have electrostatic properties which enables it to stick on a piece of glass or easily pick up shredded paper. Important tip: Do not spray your mask with alcohol spray, as alcohol can destroy the electrostatic properties of the middle layer. This will make it ineffective in trapping viruses. Use a non-alcohol antimicrobial spray instead.

3. Inner layer Made from a hydrophilic material, this layer absorbs droplets and moisture created during normal breathing. As it is always in contact with your face, the material is softer, to reduce friction and cause less skin irritation.
