"Items came quickly and were just as described. I never thought about replacing these seals until I started to get a higher and higher leak rate. After replacing them the leak rate dropped. The originals lasted two years. I bought 2 sets one to use and one as a spare."
"I've come to realize that the two seals on my four year old PR System One Heated Humidifier need to be replaced every so often.
The seals I removed and replaced were getting somewhat hard and one was cracked and causing a small amount of air to escape.
It was a simple job and I plan to repeat it at least every year or so."

"I appreciate you having parts available for my cpap machine. I'm been doing therapy since January 2013 and have broken two seals previously. When I called Liberty Medical about my second seal - they snipped at me about having to send another one. When the third one recently broke, I was disinclined to call them again because of their attitude. Your service was surprisingly prompt. The only reason I didn't give you 5 stars is that I don't need the dry box seal and I wished the seals were available separately. I've since found out that the seals are SUPPOSED to be replaced regularly. I will be dealing with you from now on. Good service, good price,"
