Vivomed Childs Face Mask 4-12 Years Pack Of 50 Mask (BFE >95%)

• Single use masks
• BFE = greater than or equal to 95%
• Bacterial Filtration Efficiency (BFE) is the effectiveness of a material to filter bacteria of a specified particle size, 3.0 µm (micron) ± µm
• The masks comfortable, covering the nose and mouth.
• Specifically designed for children aged between 4 and 10 years old.
• Designed for one way protection, to capture bodily fluid leaving the wearer.

Single use Face Mask to help prevent the transmission of viruses and bacteria.

Influenza may be a good virus particle to compare coronavirus to, as they are both transmissible through droplets and aerosol, both cause respiratory infection, and both are similar in particle size. Source for coronavirus (SARS-CoV-2) size is this paper, whilst sources for Influenza size are this paper (eventually published in Vaccine)

What is the difference between KN95, FFP2 and FFP3?

The most commonly discussed respirator type is N95. This is an American standard managed by NIOSH – part of the Center for Disease Control (CDC). Europe uses two different standards. The “filtering face piece” score (FFP) comes from EN standard 149:2001. Then EN 143 standard covers P1/P2/P3 ratings. Both standards are maintained by CEN (European Committee for Standardization).

Respirator Standard	Filter Capacity (removes x% of of all particles that are 0.3 microns in diameter or larger)
FFP1 & P1	At least 80%
FFP2 & P2	At least 94%
N95	At least 95%
N99 & FFP3	At least 99%

Therefore, the closest European equivalent to N95 are FFP2 rated respirators, which are rated at 94%, compared to the 95% of N95. More detailed information about masks and resporators and their efficiancy to protect against coronavirus and COVID-19 can be found HERE
