If you have a humidifier October/November is a good time to do maintenance. The water panel should be changed at least one time per year. Some humidifiers require more frequent replacement. Consult your owners manual for recommended change interval. Be sure and clean the water containment area. It is an ideal condition for bacterial growth. If you have respiratory problems consider the Honeywell brand water panels with Agion coating. They are slightly more expensive. They are treated to inhibit bacterial growth inside the humidifer and are available for most brands of humidifers.
Do not forget to check the strainer located in the water supply line. If it is clogged up the humidification process will be impeded.
