Do I get more humidification from my HumidAire 3i if I use the H4i Conversion Kit?
The humidification levels with H4i tubs used on a HumidAire 3i system will be equivalent to using the HumidAire 3i tubs. However, you will have the ability to take advantage of the larger 65ml water capacity for higher pressures and bilevel therapy. Additionally, the H4i tubs are offered at a lower cost than HumidAire 3i tubs.
