Install SIP Valve onto any mask

SIP Valves are reusable and can be reinstalled up to 10 times on different masks.

Replace with a new valve after 10 installs or every 30 days.

We suggest washing the SIP Valve between installs. You can wash by hand (with soap or rubbing alcohol) or throw it in the dishwasher. Dry thoroughly before installing on mask.

  • Best placement for most masks (N95, KF94, surgical, cloth)

  • Alternative for masks with a center seam (KN95)

What you'll need...


Scissors or utility knife


1. Mark your custom mouth position on the mask

Put your mask on as you would wear it (ie, stretching out any folds or pleats over your face).

- For a center install, pucker up and mark a dot between your lips (on the outside of the mask).

- For a side install, choose which side you'd prefer to drink from. Then mark the dot on your lower lip, halfway between the center and corner of your mouth.

Tip: For your first time, it may be easier to do this in front of a mirror.

2. Draw a 0.625" circle around the dot

Remove the mask from your face, and place the securing ring around the marked dot, centering it.

Using a pen, trace the ring’s inner circle. Then put aside the securing ring for now.

3. Cut a hole in the mask

Use scissors or a utility knife to cut out the circle you just traced.

Tip: If cutting into a thicker mask, it might be easier to use a knife or tip of the scissors to pierce a hole through the center of the marked circle. Once you've pierced it, you can then put the scissors through and cut out the circle.

4. Squeeze the valve head through the hole

Unfold the mask. Starting from inside the mask, pinch just the valve head and squeeze it through the hole you just made. Push it through like a button.

The valve head should end up on the outside of the mask, while the wider base should remain on the inside.

5. Slip the securing ring over the valve head

Place the securing ring around the valve, squeezing the valve head through the securing ring's hole. Again, push it through like a button.

Make sure the valve head is fully through and isn't pinched on any edge.

6. Place the cap over the valve when not in use

The cap isn't strictly needed to maintain the airtight seal. It's simply there to keep the valve clean when not in use.

Use the rectangular tab on the end of the cap to pull it off.
