Exhalation Valve Caps - Black

78 reviews


Our Patent Pending Exhalation Valve Caps are an alternative to our standard V1 and V2 one-way exhalation valves.

One-way valves offer an improved flow rate while you exhale air, helping to eliminate moisture from your face and mask. In contrast, our new Exhalation Valve Caps do not allow any air to pass through the valves – causing 100% of your exhaled breath pass through the mask filter. This design helps to further prevent the spread of airborne particulate or germs to those around you in tight indoor spaces. Some states now encourage or require this design, and we suggest checking with your local authorities.

2 Patent Pending Exhalation Valve Caps per package (each includes valve cap and cap base)
Available in teal and black
1.5" diameter in size
Compatible with all RZ Industries® mask models

*Exhalation Valve Caps only need to be replaced if they become damaged or if a piece goes missing.

*The replacement exhalation valves and caps cannot be used with NIOSH approved respirators.

Flawed, but workable.

Changing these could be made easier. The lock is difficult to seat. I wonder if the spigot of the cap were longer, and the lock required a full turn to seat if these would be easier to use.

Great idea

Easy to install. Necessary solution used at doctor visits where mask vents aren't allowed.

Great add on to make RZ Mask compliant with mandates

Remove the original valve caps, install these, and your exhaled air can no longer get to anyone else.

Obviously. It's just a cap. There was just a slight problem with stuff accumulating inside the cap. Cleaning it out is just one more step when changing the filter; not really a big deal.
