Console Humidifier Maintenance
Adding the bacteriocide is about all you really need to do. I had one many years ago. I did take it out in the driveway and scrub it up good with bleach every time I changed the pads. They start to get funky at about the same time the pads need changed. Keep a bit of something in the water to kill the nasties in between, and you won't have too much to worry about. Naturally, if you only use it in the winter, you will want to change the water and scrub it up at the beginning of each winter. That water sitting all summer will create quite a nasty stew. If anyone has asthma, a console humidifier might not be so healthy, but it seems to be your best bet for humidifying considering how you heat your home. If anyone has breathing problems, it might be better to just retire the humidifier and put up with a dry house. Either that, or change your furnace around to run the blower on low speed all the time and add a humidifier to the furnace.
