Review on Advanced Reusable Respirator for Occupational Health & Safety - TSSPLUS Pollution Washable Mask by Adam Nikolz

The materials used to manufacture this mask severely restrict the flow of air in and out of the mask, making it difficult to breathe unless you are sitting still. Even everyday activities such as walking or climbing stairs quickly make this mask uncomfortable. Airflow is so limited that I had to lift the bottom of the mask to get enough air. As I exhaled, the edges of the mask swelled to exhale. This defeats one of the mask's primary purposes, which is to prevent the escape of unfiltered air. There appears to be an external filter, but it's just a piece of foam rubber in a plastic holder on the front of the mask. I didn't feel the air when I exhaled. When I contacted the sellers and asked to return the mask, they offered me about half the purchase price and I was allowed to keep my mask - ostensibly to save them postage. I told them the mask was useless and reminded them of their Revain 100% Satisfaction Guarantee promise. I told them I would tell Revane about it. They refunded my money quickly. Your mask is in my trash.
