### ⭐⭐⭐⭐ Buy 2 of these if you want a full "set" of valves for your mask!
*by D***T on June 13, 2020*

This item contains ONE single replacement outflow valve. Since each Base Camp mask has two outflow valves, if you want to replace both of them (or to have a complete pair of two spare valves), you must order a quantity of 2 items. The supplier now allows order quantities of up to 6 items. Order accordingly! Updated rating from 3 stars to 4, based on seller incentive of free replacement item. If seller wants 5 stars they will need to clarify the item description and photo which, likely inadvertantly, seem to indicate a 'set' of two valves for sale. More recent buyer reviews after mine continue to indicate confusion regarding this issue. I suggest seller use the paragraph above to clarify their ad, removing all use of the word "set." A new picture should show the separated inner and outer valve sections, otherwise it will continue to look like a nested "set" of 2 valves (which it is definitely not). This item comprises ONE complete valve, consisting of an inner and outer valve section (shown nested together in the photo). These two sections twist together after passing through the corresponding fabric filter and mask outflow holes. This assembly holds and protects a silicone diaphragm in place (4 included in item package) to form a single one-way (outflow) valve. Although the valve is not difficult to replace, there are no instructions included. Supplier pictures indicate that a single silicone diaphragm must first be mounted on the inner valve section, properly seated over its center post and oriented with its concentric ridges forming a slight outward facing-cone. The filter replacement procedure is also the basis for valve replacement, remembering that the inner valve section must be inserted first through the filter and mask outflow holes. Once in place, the outer valve section must be seated and turned a full 90 degrees clockwise to lock into the inner section. To direct outflow in a specific direction, the inner section slots must be correctly aligned relative to the mask prior to attaching the outer section. For example, if you want valve outflow to be directed downward, the inner valve section slots must be aligned vertically, and then the outer valve tabs seated so that the outflow guides appear to be facing forward. After full 90 degree clockwise rotation to lock, mask outflow will now be directed downward. Be safe and remember that masks with outflow valves do not provide source protection. They only protect the wearer from other sources. That means if the wearer is a possible source, this mask should probably not be a first choice. The wear of outlfow valve masks may be seen unfavorably by those who know the difference. My personal practice is to wear this mask with a fabric neck gaiter, which I can pull up to cover the valves in public. Very good form/fit/function. TL;DR: Buy 2 of these if you want a full set of valves for your mask.
