Critical Installation Information

Water Quality and Hardness

Proper filtration is critical for the operation of the steam humidifier. Failure to address water quality will lead to
increased maintenance requirements and possible failure of the steam humidifier and its components. Be sure to
complete the following procedure well in advance of installation to ensure any additional costs are documented
and understood.
It is imperative to fully understand the quality and hardness of the water that will be used on each individual steam
humidifier. Water quality and water hardness can vary greatly from home to home, and even between two homes
on the same street. Water test kits are included with every steam humidifier and are also available for purchase
separately (50044721-001). Proper use of these kits will help determine which filtration option is right for each
particular installation.
Testing Water Quality and Interpreting Results
• The color block will recommend the best water filtration method for the home.
• Water test strips will be green when new.
• Honeywell always recommends installing a reverse osmosis filter.

Choosing the Filter

If the water tests in range 2 then the steam humidifier will require the use of a whole-house water softener for
optimal performance. Failure to use softened water in this situation can potentially lead to drastically increased
maintenance requirements and premature failure of the steam humidifier and its components. Water hardness in
this range negatively affects all facets of a home including shower heads, faucets, laundry machines (as well as
steam humidifier).
2
Fill the plastic tube with water directly from the
steam humidifier input water source.
Note: It is important to test the specific input to steam
humidifier, as it may differ from the faucet taps in the home.
2
Dip the colored end of one of the test strips into
the tube's water for 3 seconds.
3
Remove the test strip. Do not shake the strip.
Wait 20 seconds and then match the test strip's
color to the closest color block on the water
hardness scale.
Note: Strip color results are no longer valid after one minute.
