Guidance to buy PPE - Everbright Heal and life

  • What should we know about the N95 and KN95 masks in Canada?

    If you want to buy KN95 masks, make sure check if certain products are on the recall list. Even though these KN95 masks can be re-labelled as ordinal face masks, you'd better not buy these non-qualified KN95 masks.

    If you want to purchase N95 masks, make sure check the guidance provided on the NIOSH website to help you identify counterfeit products.

    Everbright commit to bring authentic and qualified products in to Canada. All products on our website have been inspected by Health Canada.

     

  • What we should know about the material of N95 and KN95 masks?

    Polypropylene meltblown nonwoven is the essential material to make mask. It is opacity, low abrasion resistance, no stimulation smell. Its dense microfiber structure (up to 70%) acts as an excellent barrier against particles, bacteria, and other contaminating agents. 

    Masks must achieve their separation performance with the lowest possible pressure drop – in other words, filter resistance. Pressure drop is one of the most important quality features of masks: the lower the pressure drop, the more energy efficient.

    Even mask with Polypropylene meltblown are often not sufficient to filter the finest particles from air or liquid flows. For this reason, the nonwovens are treated online or offline; for example, they are electrostatically charged to increase their filter performance. 

  • How to choose masks?

    There are many different types of masks around the world, which conform to different standards. Despite the name on the package, you should pay more attention to applicable standards.  

    The masks for medical use in China are designed specifically for different purpose of use, while all level of ASTM F2100 masks have slight difference in specification. In EU, the requirements of EN 14683 Type I and Type II are lower than China and US, Type IIR is the equivalent to YY0469-2011 and ASTMF2100 level2.

    A reference by 3M in a technical bulletin released in January 2020 demonstrates that China KN95 is “equivalent” to US NIOSH N95 and European FFP2 respirators, for filtering non-oil-based particles such as those resulting from wildfires, PM 2.5 air pollution, volcanic eruptions, or bioaerosols (e.g. viruses).
