The PRIVATE STOCK LABS masks are scientifically Engineered and Designed in New York City. PRIVATE STOCK LABS manufacturing facilities are CE certified, CNAS certified, and FDA registered.
Our medical grade, Type IIR face masks offer >98% bacterial filtration efficiency and >95% particle filtration efficiency using a 3-ply technology including a water-resistant non-woven outer layer, melt blown center, and an absorbent non-woven inner layer. These three layers work together to make a lightweight, breathable mask that is good for all day wear for even the most sensitive skin.
Our masks are Type IIR, meaning they meet the following criteria during rigorous testing:
- The highest BFE (bacteria filtration efficiency) of >98%, ensuring better protection from bacteria
- The highest PFE (particle filtration efficiency) of >95% (0.3μm; NaCL; 32 l/min), ensuring better protection from particles
- Excellent breathability measured by a Differential Pressure of <60 (Pa/cm2) (Airflow 8 l/min), ensuring the mask feels cooler and easier to breathe through, maintains its shape better, and has less unfiltered air escaping around the mask.
- Superior microbial cleanliness of <30 CFU/g (CFU-Colony Forming Units), ensuring a cleaner mask.
Our masks are designed with three layers that all perform very specific functions — a water-resistant outer layer to block airborne contaminants, a melt-blown fabric center to filter bacteria and particles, and a moisture-absorbing interior. These layers work together to protect both yourself and others. Both 2-ply and cloth face coverings (usually made from polyester or cotton), just can’t measure up because they are not constructed the same way. They may block some expulsion of airborne contaminants but offer minimal protection against pollution, viruses or bacteria.
What is BFE - Bacterial Filtration Efficiency? BFE measures the filtration efficiency of a mask using viable (live) particles (bacteria) that vary in size from 1 to 5 microns.
What is PFE - Particle Filtration Efficiency? PFE measures the filtration efficiency of a mask using nonviable (nonliving) particles that are fixed in size from 0.1 micron to 1 micron. A face mask relies on microfiber filter media technology to capture the submicroscopic particles generated by high-speed handpieces, ultrasonic scalers, and lasers commonly in use. The HIV and TB pathogens are approximately 0.1 micron and 1.0 micron, respectively.
Step 1: Wash your hands before touching your mask.
Step 2: Pull the mask straps around your ears with the PRIVATE STOCK LABS logo facing outwards.
Step 3: Stretch the mask across your face so it snugly covers your nose, mouth, and chin.
Step 4: Pinch the upper edge of the mask so that it presses gently on the bridge of your nose.
Step 5: Avoid touching your face or the mask once it’s on, and use the mask keeper to store your mask when you need to safely stash it between uses.
Step 6: Dispose of the mask properly after its 8 hour use.
Our PRIVATE STOCK LABS masks can be used daily to protect from bacteria, dust, pollen, smoke, debris and germs from seasonal cold and flu. Plus, our masks are super breathable and lightweight, making them easy to wear for long periods of time.
What is the importance of fluid resistance? In the dental environment, it is very important that the mask you wear is fluid-resistant unless you are only performing an oral exam. A fluid-resistant mask does not permit blood or other potentially infectious materials to pass through to reach the skin, nose, mouth, or other mucous membranes under normal conditions of use.
With proper care, a single PRIVATE STOCK LABS mask can be used approximately 8 hours. To keep it clean during its daily use, use our mask keeper to stow your mask safely when not in use (no more stashing in dirty pockets and purses).
