🌬️ Dust Resistant Lightweight Accessories for Enhanced Breathing Review

I was upset when one of the valves on what I thought was a good mask broke. I tried contacting the company but they didn't seem to work anymore so I was pleasantly surprised that they fit almost exactly the same. Thanks to the large packaging, I can just throw them away when I feel like they're dirty.

Poor quality like the last ones I bought from another company. You can open them and flip some of them or straighten them and they're fine, but some are just junk and unusable. You should test each one individually and see if it covers the hole, then check for air before installing.

I carefully inspected and disassembled these mask air check valves and found them to be poorly made. 1. The silicone seal/flap allows air to pass through at a low suction rate, which is common with most masks as the air also passes through the filter. It only appears to be fully functional when the air intake has been concentrated directly in the valve due to the higher air intake velocity driving the shutdown.2. The plastic case is of poor quality and the brackets shouldn't last very long…
