They just work
They work exactly as described.
Glad valve was re-engineer to replace Membrane as I was loosing it
Masks and valve caps
Would give 5 stars if the valve caps were standard on all masks since a major use is for covid19. I have to buy the valve caps every time i get a new mask and change them before using the mask. Out of about a dozen masks and sets of valve caps and years of use one cap broke and fell out while i was wearing it which was inconvenient but RZ replaced it immediately when i let them know what happened. Really like the masks—they feel more secure than any other kind.
Making it safe!
My employer mandated that we could not use exhalation valves on our masks due to the pandemic. RZ came up with the perfect solution with these caps! Keeps me safe and keeps those around me safe. Win-win!
The product is great. I have some trouble getting them to stay in place.
Mask is great however due to covid should use surgical mask underneath..
An excellent addition to your lines in these times. Purchased for all my staff
These caps lack the little silicone wafer that the originals have, but otherwise a great swap for the current ongoings.
Love the caps but really hurt my fingers to put them on my mask. I lost my bag/key and when I called to BUY another bag/key, I was informed that isn’t an option, that I had to buy another mask (that I don’t need and would still leave me with one mask without a bag). Seriously?!?!?
Have placed them but not used the mask yet. Looking forward to keeping us all safe.
