HempGuard engineers Mother Nature’s material for a better world, making it the world’s first plant-based filter, embracing the Vegan philosophy. Hemp is naturally anti-bacterial and anti-microbial, the only one of its kind in the MERV 8 category. Using Lean Six Sigma methodology, and inspired by the Japanese error-prevention method known as Poka Yoke, the HempGuard has been specifically engineered with fool-proof installation in mind.
