H4i™ Heated Humidifier Top Cover Lid and Seal

good humidifier alteration

Perry H, TX – December 18, 2012

"I upgrades from my H3 to the H4i on my S8 CPAP. I like the fact that you can clean the H4i tank. If you purchase the H4i tank, you must purchase this cover to retrofit. Replacement was easy. My only complaint for the H4i is that it uses water faster but that is probably a good thing. You will be refilling your tank every night no matter the temp setting."

"It works well, I wish they said this was a requirement when I bought the new humidifier chamber. I would have purchased it anyway, but I could have been using it sooner."

Exact Replacement
