Previously I had read where someone questioned whether you could boil the pillows to give them additional life. There was concern about the gel and the effect boiling would have on them.
I boiled two pillows for 30 minutes without any damage to the pillows and it did soften them up for additional comfortable wearing.
I have been using 2" wide blue masking tape. It works very well and it is easy to remove. I used Johnson & Johnson paper tape for several years and found it to be much stickier than the blue masking tape. With both tapes it is important to wash with soap around your mouth to get the oil off so the tape will stick better.
My sleep apnea tech almost had a fit when I told her I was using tape because she said if you get sick and vomit, you could choke to death. I make sure I fold on end over about 1/8" for a "handle" to get it off easier.
I use a similar CPAP nose device. I had to tape up my mouth with paper Johnson & Johnson tape. This sounds extreme, but it worked for me. I can cough and sneeze with the tape in place and it stopped the air leakage through my mouth.
I wash around my lips with soap to get the oil off and then apply. Hope this helps...
