Get started with your B2 Mask
Before you unbox or interact with your B2 Mask, wash your hands with soap and water. Be sure to scrub all surfaces of your hands and in between your fingers for 20 seconds.
Okay, ready to go!
Assemble your B2 Mask
Select
Select a filter set, containing 2, from your filter pack.
Insert
Insert the filters, printed or colored side out.*
*B2 Filter Lite does not have a printed side and can be loaded in either direction
Secure
Secure filters with filter caps, rotating fully.
Orient
Align the facepiece (99 logo up) with the outer fabric covering (smaller elastic strap up).
Attach
Hook the overlay centerband under the 4 angular tabs located on the outside of the facepiece.
Secure
Gently pull on the lower straps in order to secure the overlay and facepiece.
Wear your B2 Mask
Understand placement
The facepiece should be positioned low on your nose and resting on the surface of your chin.
Place and secure
Making sure the larger straps are on the bottom, secure both ends around the back of your head. Position the elastic strap behind your head.
Adjust strap
As you wear your B2 Mask, you may want to make adjustments to the fit for seal and comfort.
Optimize your B2 Mask seal
Adjust seal
The optimal seal can take time to find as you get use to wearing your B2 Mask. To improve the seal, try placing the mask higher up on your nose bridge, and then gently pull down.
Seal inversion
You can also try to invert the seal of the facepiece near the nose for a tighter seal.
Cleaning
Remove your filters and dispose of them before cleaning the rest of your mask. The facepiece, filter caps, and fabric overlay may be washed by hand using a mild soap or detergent. Alternatively, you can place them all in a laundry delicates bag and machine-wash on the delicates cycle with cold water, laying them flat to dry. Once everything is fully dry, insert new filters and reassemble your B2.
Storage
When not in use, the B2 Mask can be folded in half with the overlay straps used to secure it closed. Alternatively, the mask can be left on a clean surface or hung somewhere that is out of the way. Do not store in a sealed container because this prevents moisture evaporation.
