Thread: Lather and Hard Water

If you want the cheapest and best method I'll tell you what it is. Air O Swiss sells Ultra Sonic Humidifiers and to eliminate White Dust from hard water they have a cartridge which contains resin like a water softener does. You can buy just the cartridge and get refills for it for about $12 for a complete cartridge and a box of 3 refills is about $20. All you need do is put the cartrige in a gallon or so of water and leave it there 24hours and you'll have the softest water in the world and you can reuse it quite a few times.
