BestAir 3BT-PDQ-6 Original BT Humidifier Bacteriostatic Water Treatment, 32 fl oz, Single Pack, Green

I just finished my first bottle of this stuff.I was a little shocked at the toxic labelling. But then realised that is in the concentrated form straight out of the bottle. Like chlorine used in pools and drinking water. Chlorine is highly corrosive and deadly in the concentrated forms used in pools. Don't eat it, don't touch it, and try not to breath it. BUT, you dilute it with water and when controlled as directed, it's fine.After using a full bottle, I feel confident the diluted form in the water and then the ever more diluted form that is in the air seems safe. But what do I know. Also, different liquids evaporate at different temperatures. So I wonder how much of the diluted chemicals even make it into the evaporated water.Either way, after 1 winter down, I didn't notice any breathing issues, smells or other affects from the use of this product. And I even do cardio in my home where the humidifier works on the whole house.I did notice that if you add this before filling with water, it gets very foamy. So I fill with water first and then add this solution. No foaming.We also have a water softener for our home, so I don't know if that has affected the efficiency or use of this product. I don't have any proof, but the water seems clean and the tanks seem to stay clean longer and without build up. And my wicks seem to last a long time without build up. And no foul or chemical smells for me.

Easy to use. Best cost around. Pleasant smell. Perfect for the humidifier

This stuff really helps keep my humidifier from smelling funky. I just add a little each time I fill it, and it wroks well to stop any build-up or slime. The bactireostatic formula seems to do what it’s supposed to, and my water stays fresher longer. Just check out the image. I haven't seen it clean like this in a while. Only reason I gave 4 stars instead of 5 is because I wish the bottle had a smaller spout for easier pouring. Still, it’s been great overall andhelps my humidifier clean and run smoothly without much effort. Must add for a kids room to keep them healthy!

Purchased to help keep my humidifier cleaner, it's helped cut down on the pink mold we get that just happens. It is not a cure-all, still needs washed but this allowed me to extend it until the weekend vs twice a week. Bottle doesn't leak, it's easy to handle and has no smell, which was wonderful.

This stuff actually works. I was having trouble with constantly having to clean my Vicks cool mist humidifier...it would get scummy and the wicking filter would turn brownish and crusty. I used the drop in tank cleaning cartridges that were recommended by the manufacturer and they worked for maybe two weeks (the month of sanitizing action that was claimed was stretching it IMHO)...that's just not good enough for me considering their price. I run my humidifiers CONSTANTLY in the winter and I was getting tired of replacing wicking filters and having to totally clean out the tray under the tank on a weekly basis - I'm a busy girl on a budget.Read the reviews for this product and decided to give it a try. It really works. I add 5ml to the tank each time I fill it up (once a day) and I see NO MORE SCUM/BIOFILMS forming in any part of the tray, on the filter, or in the tank. No discoloration. I wish I had a before picture but attached is how my wicking filter looks after AT LEAST a month of constant use...clean and moist. Before using this product after the same amount of time I would see discoloration always in the filter.Also I was pleased to see the large size of the bottle. I always expect to receive bottles of product that are much smaller than I had expected. This will last a long time - easily one winter and then some. I keep it right under the sink where I fill the tank along with a 5ml syringe ( I work in a lab). Easy peasy. Don't waste time with anything else.ps. I don't write reviews..so this product really impressed me
