Humidifier question

[Reine]

What is the difference between Humidaire H4i Heated Humidifier and Humidaire H3i Heated Humidifier ?
I found the answer to my question.
ResMed's HumidAire 4i is engineered to deliver 30% more heated humidification than the H3i. The humidifier is an integrated unit for use with ResMed S8 and S8 II series CPAP machines. The H4i Water Chamber has also increased in capacity up to 390 ml of water.


My machine is set for H3i but I have the H4i . Would this be a cause for sinus problem. If so should I try to set the machine to H4i I have set the humidifier to 0 and it seems to help some. When someone refer to standby mode is it set to 0?

My understanding is that the HH4 being so new, the machine's do not have it in their internal software/hardware to recognize the HH4. It hurts nothing.

You mention sinus problems. Some people do better at higher humidity, some do better at lower humidity.
I do better at very high.. I experience extreme congestion and allergy like symptoms at lower levels.

So each to their own. Set to zero would mean that if you have water in the machine and air blowing over it, you would be getting what we refer to as "passover" mode humidity. It would not be heated humidity.
Passover mode would result in very minimal moisture in the air going through the CPAP.

thank you for your reply Pugsy. I will try it at o.5 to get some heated humidity.

Hi Again Reine.

Given we are in similar climate (Mississauga here). My DME told me to set it to 3. I got rainout, tried it at 2, got rainout. I don't get rainout at .5 and 1, but since it's been so humid lately, I've set it to passover mode (no heat). During the colder months .5 and 1 were fine.
