So I washed the Airtouch F20 Mask with Memory Foam

[Dave W]

Just wanted to add my 2 cents.

I clean daily with one drop of dawn and water. I try to keep the water away from the foam. And I use 2 at any time, rotating by day. So they have 36 hours to dry out. AND....I write date of first use right on mask with indelible felt pen. 

Also write inception date on tank, hose, & head gear. 

As for price it's hard to beat that place with all the trucks.

That is a really good idea. I have seen rolls of tape or adhesive labels or zip tie labels. I keep a record of my insert and when I start using a new one etc within OSCAR but it might be helpful to have that on the other stuff too.
