The Honeywell HWM-950 is a top-fill cool mist humidifier designed for medium to large rooms. It features a large tank capacity, adjustable humidity control, a wicking filter, an easy-to-clean design, and a quiet operation mode. The tank cap is a critical component for safe filling and operation. Below are key sections for safety, features, installation, setup, operation, maintenance, and troubleshooting specific to the tank cap and overall unit.
Key components: Main humidifier base, Water Tank, Tank Cap, Wicking Filter, Humidistat Control, Quiet Operation Mode, Indicator Lights, and Easy-Top Fill design.
| Feature | Description |
|---|---|
| Tank Cap | Secure, twist-lock design for leak-proof filling and transport |
| Top-Fill Design | Allows easy filling directly into the tank without removing it from base |
| Adjustable Humidistat | Dial control to set desired humidity level |
| Wicking Filter | Traps minerals and impurities; requires periodic replacement |
| Quiet Operation | Low-noise setting for night-time use |
| Tank Capacity | Large volume for extended run time |
| Indicator Lights | Power On, Tank Empty, and Filter Change indicators |

Unpack all parts. Place unit on a stable, level, waterproof surface away from electronics.
WARNING! Use only clean, cool tap or distilled water. Do not use hot water or additives. Ensure tank cap is securely fastened after filling to prevent leaks.
Before first use, clean the tank and base according to cleaning instructions.
CAUTION! Always turn off and unplug the unit before filling, cleaning, or servicing. Handle the filled tank with care; it is heavy.
Control Panel: POWER Button, HUMIDISTAT Dial, QUIET MODE Button, Indicator Lights (Power, Empty, Filter).
Operation: Power on, set desired humidity level. The unit will run until set humidity is reached, then cycle on/off automatically. Use QUIET MODE for reduced noise. The TANK EMPTY light will illuminate when refill is needed. The FILTER CHANGE light indicates when to replace the wicking filter.
Tank Cap Role: Must be securely tightened after each fill to create a proper seal, enabling correct water flow and preventing spills.
The top-fill design with a dedicated tank cap simplifies refilling.
Tip: For easier handling, you may remove the entire tank to fill it at a sink, but the top-fill cap allows filling in place. Always ensure the cap is sealed before moving the tank.
Regular cleaning prevents mold and mineral buildup. Clean every 1-2 weeks during use.
WARNING! Never use harsh chemicals, abrasives, or submerge the electronic base. Always dry the tank cap gasket area to ensure a proper seal.
The wicking filter should be replaced every 1-2 months or as indicated by the FILTER CHANGE light.
Note: Using the humidifier without a filter or with a damaged filter can lead to white dust output and reduced performance.
When not in use for extended periods, prepare the unit for storage.
CAUTION! Never store the unit with water in the tank. Ensure the tank cap is left slightly loose or stored separately to prevent odor buildup.
