How to descale your InvisibleMist™ pump & tank
Regular descaling helps keep your humidifier working its best by removing mineral buildup from the tank and pump. Follow the steps below to clean your humidifier using citric acid descaling powder.
Before you begin
- Unplug the humidifier.
- Rinse the inside of the tank with fresh water.
- Wipe away any loose or visible mineral buildup with a clean towel.
Step 1: Mix the Descaling Solution
First, fill the tank with 2 L (0.5 gal) of water. Then add the descaling powder and mix well.
For monthly maintenance
Use a 2% descaling solution.
Add 1 pouch (1 oz) of descaling powder to 2 L (0.5 gal) of water.
For heavy buildup or pump issues
Use a stronger 4% descaling solution.
Add 2 pouches (2 oz total) of descaling powder to 2 L (0.5 gal) of water.
Important: The tank should be about halfway full. Always add the water first, then the descaling powder.
Step 2: Let the Tank and Pump Soak
- Remove the sponge pre-filter from the pump and place it directly in the tank.
- Place the pump into the tank as you normally would during assembly.
- Make sure the bottom half of the pump is fully submerged in the descaling solution.
- Let the tank, pump, and sponge pre-filter soak for 2 hours.
Step 3: Rinse and Reassemble
After 2 hours:
- Remove the pump from the tank.
- Thoroughly rinse the pump, sponge pre-filter, and tank separately with fresh water.
- Reassemble your humidifier.
- Fill the tank with fresh water before using it again.
Your humidifier is now ready to use.
