My humidifier uses wick filters and I'm replacing the filter every 2-3 weeks. I've tried various water treatment solutions, but they're expensive too. Can anyone please recommend solutions which don't involve spending a lot or which use common household ingredients and not a number of questionable chemicals? Our water is reasonably hard and fluoridated. Thanks kindly.

I would like to know the answer to this too. I bought a brand new humidifier and after 2 weeks, the filter is hard and will not put out any mist. We have hard well water also. I have bought so many filters that I am not willing to do it anymore
Don't know cause I haven't dealt with this but couldn't you put a water filter on your sink faucet and use that water in your humidifier?
First, see if you cant' make a filter out of the same thing the furnace uses. I used to make my own vacuum cleaner filters that way, but I'm not sure it it would work with moisture.
Most of the time I've found that cleaning the filters in a mild beach or vinegar water will clean them. I've elongated the life of my filters three-fold by doing this.
I use bleach and water to soak the filters about once every ten days. Make sure you use gloves, and don't squeeze the filters, just rinse them afterwards. It will have a slight bleach smell for a day, but it will give the filter about six months of lifespan. I've also heard citric acid is good for removing minerals, but have not tried it.
Home Depot makes tablets to treat the water in humidifiers and it's less than $2.
ONLY use distilled or R/O filtered water which TDS tests to zero. And you'd be bette off if you would switch to an ultrasonic-type humidifier then you could clean weekly with bleach or vinegar. With ultrasonic type they require no filters.
