Honeywell Reverse Osmosis Filter System With Pump for TrueSTEAM Humidifiers

This Reverse Osmosis (RO) filtration system removes dissolved solids and organic matter from water by passing it through a membrane which separates and flushes minerals and impurities from the water. Install this system upstream of the steam humidifier's water inlet. It is recommended that the RO system's filters be replaced at least once per year to ensure optimal humidifier performance.

In areas where water is moderately hard to extremely hard - a dedicated reverse-osmosis systems is recommended to reduce and simplify maintenance for the TrueSTEAM steam humidifier.

This RO System (50045947-002) is for homes with water pressure lower than 45 psi. It includes a permeate pump which helps to boost water flow for these lower pressure applications.

System Includes:

  • RO manifold assembly
  • Supply tubing (one 20 ft. long 1/4" dia. white tube)
  • Adapter elbow (3/8" x 1/4")
  • Drain line assembly (including one 6.5 ft. long 1/4" dia. red tube, one 1 ft. long 1/4" dia. red tube, and drain flow restrictor assembled in drain line fitting)
  • Mounting screws and washers
  • #1 - Sediment filter
  • #2 - Reverse osmosis filter
  • #3 - Staging tank
  • Storage tank
  • Storage tank tubing (one 6 ft. long 3/8" dia. yellow tube)
  • Shutoff valve
  • Teflon tape
  • Permeate pump
  • Mounting bracket and screws
  • Tee fitting

RO System Assembly
The RO System Assembly directs the flow of water into the filters in numeric order, and out to the steam humidifier. A built-in backflow prevention valve prevents the backward flow of water from the storage  tank. The shutoff/check valve provided with the steam humidifier must still be installed between the RO system and the steam humidifier.

#1 Sediment Filter
Cold water enters the sediment filter, reducing chlorine, sand, silt, dirt and other sediment. This filters the feed water before entering the RO filter.

#2 Reverse Osmosis (RO) Cartridge
Filtered water enters the RO filter where dissolved minerals are removed, effectively 'softening' the hardness of the water. This reduces the amount of solid mineral  (scale/sediment) fallout inside the steam humidifier's tank. Reducing the amount of scale and sediment increases the time between manual cleanings of the steam humidifier.

#3 Staging Tank Canister
After leaving the storage tank, but before going to the steam humidifier, water enters the #3 staging tank canister. This canister holds the initial water that enters steam humidifier when the solenoid fill valve opens.

Storage Tank
The storage tank holds filtered water. A diaphragm inside the tank keeps water pressurized when the tank is full, to provide fast flow from the RO outlet. The tank is charged with 5-7 psi air. The automatic shutoff valve fills and pressurizes the tank when low, and stops the flow of water when the tank is full.
