Humidifier August 02, 2008

rating:4 (4 out of 5) by Annoymous User

"I have used this humidifier for 3 yrs. The last tank was much more flimsy and cracked and leaked a lot. I hope the newer design is more sturdy. I have the GOOD KNIGHT 420E, so I'm stuck with this humidifier, I'm not sure if any other humidifer is compatible, but CPAP.COM service can't be beat."

"THIS HUMIDIFIER PUSHES THE WATER THROUGH THE HOSE. I GET A NOSE FULL OF WATER ALL NIGHT LONG. I QUIT USING IT AND USE MY STANDARD NON HEATED HUMIDIFIER."

Works Very Well July 16, 2008

rating:5 (5 out of 5) by Brad P, OH

"No complaints. It does what it's suppose to do. The one concern I have is that the humidifier has to be turned on seperately from the CPAP 420G machine, causing me some concern that - a)I will forget to turn it on after turning on the CPAP 420G, and/or b) I'll forget to turn it off in the morning. So far, this has not been a problem."

H20 Humidifier July 15, 2008

rating:4 (4 out of 5) by David S, Simi Valley, CA

"Smart product... makes the entire package (cpap with humidifier) a reasonable compact piece of equipment. It will work well when traveling.

Only complaint and I'm not sure it's curable...is that it is somewhat difficult to refill the water...just a little awkward to get to the filler... But certainly not a big deal.

Altogether I highly recommend the entire unit, whether as the home base cpap or as a travel unit. It works."
