[Easy on/off]: Flo Mask has an adjustable elastic top strap with a non-slip design and a universal elastic bottom strap, which makes it easy to wear for any kid. [Our Story]: Flo Mask was create by award winning designers from the Silicon Valley.Our StoryFlo Mask was created by an award winning product innovator based in the Silicon Valley. As a dad to three young kids, his mission, which begin in 2018, was to develop the most effective mask for kids. Aiming to protect them from the annual California wildfires, and now, a raging pandemic, this mission became deeply personal. He and his world class team of product designers spent two long years and dozens of prototypes later to finally bring to life a mask worthy of not just their own kids wearing, but yours.Air Flo Labs competed against 1,500 other innovative mask designs across the United States and was recognized as a winner of the Biden Administration’s Mask Challenge, hosted by BARDA/NIOSH. This prestigious award was presented to the company in a ceremony led by the Director of the Biomedical Advanced Research and Development Authority on June 24, 2021.Note: Health Canada has not authorized these face masks for the Canadian market as a medical mask.The top elastic strap is adjustable, detachable, and has a non-slip pad.Flo Mask weighs only 1.5 ounces making it extra comfortable to wear.Flo Mask uses Technostat filter media technology which is proudly made in the USA.It starts with the right fit.Kids faces come in all shapes and sizes. That’s why we used the very best 3D scanning technology to scan elementary aged kids across multiple ethnicities.Layering this 3D data on top of each other, we were able to create a unique shape to our mask, optimized to fit kids as young as 4 and up to 12 years of age*. Patent PendingWe then focused on comfort, both physical and respiratory.Flo Mask was engineered with the latest advancements in manufacturing, using LSR liquid silicone rubber to create a pillowy gasket that contours along the face for a solid seal.We designed Flo Mask with generous air flow openings, allowing those little lungs to breathe easily and comfortably through a pure filter layer.Sub-micron filtration, made in the USA.Flo Mask uses Technostat filter media technology which is proudly made in the USA, filtering particles smaller than a micron.Our unique manufacturing process uses a needle punch non-woven textile that is electrostatically charged, making it incredibly efficient at preventing airborne particulates from passing through.This spunbond process also makes breathability much better than traditional meltblown filters.Each filter is rated for 8 hours of continuous use.
