How to Clean Humidifier Pads

A humidifier is used to add moisture to the air. The process used calls for keeping a supply of water in the humidifier, and a filtering pad, which constantly moves and lifts the water. These pads can get caked with sediment and hard-water mineral particles, as well as mildew or algae-type growths if they aren't cleaned regularly. Cleaning the pad should be part of monthly humidifier maintenance.

Things You'll Need

• Ammonia
• Vinegar
• Baking soda
• Tub or large sink

Instructions

1. Fill a tub with very hot water. You will need the water at least 6 inches deep.

2. Add 1 cup of ammonia--regular or unscented, it doesn't matter. Ammonia will get the pad deep-down clean, lifting away the hard water and mineral deposits.

3. Mix in 1 cup of vinegar and 1 cup of baking soda. These will create some bubbling and fizzing as they create a chemical reaction. Baking soda and vinegar not only help clean, but they also kill mold and mildew spores and algae.

4. Place the humidifier pad in the tub, submersing it completely, and allow it to sit for 30 minutes. By this time, the water should be cool enough for you to place your hands in it.

5. Use your hands to agitate the pad in the water. This works similarly to a washing machine by moving the water through the pad and washing away the buildup. Also lift and dunk the pad several times to remove minerals and other debris that may be caught in the fibers. Be careful not to stretch or tear the pad.

6. Rinse the pad under hot running water and lay it flat to dry for an hour before installing the pad in the humidifier.
