Abstract
A filtering system for use with a reservoir. The filter system includes a filter assembly capable of filtering particles sized 1.0 micrometers and larger and may, include a flow control device positioned to selectively provide fluid flow to the filter assembly. The flow control device may include an electrically actuated valve, such as a solenoid valve. The filter system may also include a fluid level detection mechanism operatively connected to the flow control valve. The filtering system is especially applicable to humidifier systems having a heat source
Claims14
A humidifier system, comprising:
- a) a reservoir configured to contain a fluid;
- b) a heat source configured to heat fluid within the reservoir;
- and
- c) a filter assembly for filtering the fluid prior to its flowing into the reservoir;
- d) an electrically-activated valve positioned to selectively permit fluid flow from the supply source to the filter assembly;
- and
- e) a fluid level detection mechanism to detect the fluid level in the reservoir wherein the fluid level detection mechanism is operatively connected to the electrically activated valve.
