We like the mask and filter which is easy on the skin. But the valves fall out with a lot of removing and putting back on. Why not put an extra set of valves in each package.

RESPRO’NSE: “Great to hear the mask is working well for you. Re the valves, are you replacing your filters in the correct manner? Please check the video https://www.youtube.com/watch?v=b2XIXeCVmVw to see how to replace a filter. It is the same for any Respro® mask;valves fits on filter, filter with valve attached, then fits into shell. If you put the valve directly into the mask and filter it is likely you will not secure it properly, hence the valve dropping off. Hope this helps.”
