"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."
"I purchased a replacement lid for my Res Med. Works great. Sturdy. I can sleep again. Very happy with the product."

"I was traveling and my old cover was broken. I panicked but remembered my old friends at CPAP.com! I ordered this replacement and it works perfectly!"

"I was expecting to wait at least a week for the H4i Heated Humidifier Top Cover Lid and Seal to arrive, but it was delivered three days after I ordered it. It works perfectly. I am very pleased and I am sleeping well once again."
