Passes the "sniff test".
I'm a medical professional and Mom of 3 kids. I researched this product extensively before using it. I thought I would share what I found: A clinical study was conducted in 2006, which showed this product was extremely effective at killing germs and mold in humidifiers (Journal of Water and Health, vol 4.2, 2006). Also, it's shown to be very safe and 100% natural (based on natural silver technology...the active ingredient in the cartridge is actually used in many drinking water filters found at the "big box" stores.) One point to mention: it doesn't remove minerals. If you get stains in your humidifier from iron in your water you'll need a demineralization product for that (or use filtered or distilled water). I use it and highly recommend it.

It works.
After paying well over a hundred dollars for a humidifier, I got so tired of the sloppy job of cleaning slime out of it that I was almost ready to throw the thing away. After replacing its $15.00 filters (every 3 months) that seem to do about nothing, it didn't seem worth the cost and effort to keep it operating. The unit's instructions advised me not to use any additives but just clean the thing about every filling and keep replacing those filters as directed. So, since I was going to throw the thing out anyway, I tried one of these cartridges. It worked. It's been about a month, and the slime is starting to come back, but that's supposed to be the effective life of the cartridge. The humidifier survives. I still have to clean it, but the task is now infrequent and easier. So, it does what it's supposed to do; does it for as long as it's supposed to do it; hasn't harmed the over-priced humidifier; and is good for the environment as long as it keeps this...

it is an expensive unnecessary
The cartridge costs about $5 and last only 20 days before the filter and the cartridge starting reek. However, I found that Holmes Bacteriastat cost about $7 and could last for a season and it also extended the life of the filter. My suggestion is to buy the Bacteriastat.
