Pure Humidifier Replacement Parts
237 parts
Genuine OEM replacement parts for PURE Humidifier Co. commercial and industrial steam humidifiers — the ES, EC and ER electric steam series, GX gas-fired units, SX steam-to-steam heat exchangers, and DDR drain and float assemblies. Stocked here: cover and side-entry gaskets, fill and drain valves, tri-probe assemblies and O-rings, float ball and arm assemblies, over-temperature and liquid level switches, SCR relays, GX ignition electrodes and flame rods, and PUREClean descaler. Beyond what's on the shelf, we also list the full factory parts lists for each series as request-a-quote items — no price shown, quote and lead time on request.
These parts are for PURE Humidifier Co. of Chaska, Minnesota — commercial humidification equipment used in healthcare, entertainment, aerospace and commercial building HVAC — not the Pure Enrichment consumer humidifier line.
Built for the trade
This catalog is built for licensed HVAC contractors, facilities engineers, and property/building maintenance teams — not general consumer DIY installation. Every part showing a price is real inventory on our shelf, verified before it goes live; parts marked "Request a quote" are genuine PURE parts we can order but don't stock yet.
How we ship
Free ground shipping via UPS or FedEx Ground on US orders of $50 or more; orders under $50 ship for a flat rate, shown at checkout. In-stock orders before 1pm ET ship the same business day.
