Mask Filter Insert
Mask Filter Insert Properties
Our Nano47 Mask Filter Insert are made from melt blown polypropylene fabric, antibacterial, odorless thin lightweight for easy breathing.
Melt blown manufacturing is a process used for creating all non-woven fabrics that have special properties such as:
Ideal Filter For DIY Masks
The filtration material used in an N95 mask is a meltblown non-woven polypropylene fiber.
This is what makes an N95 an N95.
This material is not commonly available.
Perfect Middle Layer Filter
Do Cloth Masks Provide Protection?
Woven materials are effective when in multiple layers but better yet, materials where the fibers are randomly bonded, in an amorphous tortuous pattern.
The ideal mask filter insert for DIY masks is a Nano47 filter currently being used in N95 face masks and hospitals, because it is both nonwoven and hydrophobic (repels water and respiratory droplets).
Nano47 Mask Filter Inserts still work well after 2 or 3 uses unlike medical masks filters that lose filtration efficiency within a day.

Respiratory droplets can be of various sizes and are commonly classified as aerosols (made of tiny droplets).
Larger droplets do not travel distances more than 3–5 feet and settle due to gravity, while smaller aerosols remain suspended in the air a lot longer due to their size and play a key role in spreading infection.
IMPORTANT: A combination of physical barriers such as respiratory face masks and filter inserts is crucial and very effective in mitigating the spread of tiny respiratory droplets (aerosols).
