Autoflo 200P Humidifier Parts

The AutoFlo 200P humidifier is a whole house bypass style humidifier. It is important to replace the humidifier filter at least once per year with a new AutoFlo 200P humidifier filter available on this page.

The original float valve for the 200P was a part 401972. That float valve is OBSOLETE but was replaced by another float valve assembly part 188. Unfortunately the 188 float valve assembly will NOT work in the model 200P because it is too long and hits the other side of the water tray. If you need a new float valve assembly for your model 200P you must purchase a new humidifier. We suggest the model 800BP shown on this page. The 800BP is functionally similar to the 200P but may require modification to the hole in the plenum.
