HM750 Electrode Humidifier Replacement Canister

This is my first use of replacement canister. The original canister lasted three years almost to the day when the unit started reporting low current flash code. I'm using an RO filter that outputs about 25 TDS for comparison. This replacement was easy to install and worked right away. Only had two minor difficulties. I drained the system, disconnected power, and waited a while. After disconnecting wires, the rubber hose was stuck to the canister tip. Took a little gentle prying with a screwdriver around as much of the edge I could reach until it detached. The canister pulled out fine, then some black water leaked out from the bottom that was like dissolved rubber, not too uncommon with o-rings in plumbing. Be prepared to catch a little fluid. Another ordered to replace in another two to three years.

Expensive for a single use product, would love a star that could be de-scaled and reused. Before installing a steam humidifier in this style make sure you have decent quality of water. Check the electrical conductivity of the water supply—if it is too high you'll go through many of these and they are not cheap. I hope Honeywell produces a model that is good for high conductivity water, as well as a model for low conductivity so more customers can utilize these systems.
