Product review (5 stars): Amazing for your humidifier
This stuff is AMAZING. I've had it about 3 weeks now. Backstory: Originally had a Vicks humidifier, stop using it because the filter molded in a week. So if you kept using it - you had moldy fresh air coming at you all night. Yuck. Bought a filter less unit that wasn't near as good and leaked every night. Ugh. Did some research and came across this. I just out a drop or so (maybe like a tablespoon or so?) in the reservoir every night/ other night. We've had the same filter for 3 weeks now and it's still white!!!!! I just have a cool mist humidifier, but it's fabulous. Will be buying more when we're out - I'd say I have around half a bottle left. Great investment!
