The powerful ion exchanger in the Cartridge removes calcification in the water to prevent white dust often created by Ultrasonic systems. It lasts up to three months, depending on the water's hardness. Suitable for most Ultrasonic humidifiers with a standard tank cover.
Comments about Stadler Form Humidifier Cartridge 2 Pack:
I did a lot of research, and decided this was the good-quality product I was looking for.
Service and delivery comments:
One cartridge was mistakenly not sent with my original order. Drugstore.com more than made up for this by sending two new cartridges, and a very nice apology. I'll remember this - and I'll be back to shop here again because of this fine customer service.
Was this a gift?:
Bottom Line Yes, I would recommend this to a friend
