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

Bought the three pack for our work humidifier and saw that it completely eliminated mold/mildew/bacteria in the water and on the filter. I bought a bottle for my home humidifier. It works great. Very satisfied with this purchase.

Add it to humidifier every time , works great and extends filter life

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!

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

I've been using this product for about five to six months of every heating season since I purchased my two-tank Vornado Evaporative Humidifier with two wick filters approx 10 years ago after another type died within the first few weeks of use. In that time I have never had any unpleasant odors or sign of algae or mold while using it. I also use a Holmes water treatment product to control mineral buildup. I did try a product from BestAir for its claims to also control mineral buildup on the wick filters. Unfortunately, it made my humidifier maintenance chores worse instead of better---I went through much more vinegar dissolving the hard yellowish-buildup than I usually do. As for measuring & dispensing, since the cap on this Original BT Humidifier Bacteriostatic Water Treatment has been made sooo very much smaller, and the cap on the Holmes product I bought in bulk years ago is also very small, this year I've been dispensing them using one of these droppers katito White 3ML Disposable Plastic Eye Dropper Set Transfer Graduated Pipettes (20 PCS) , after I measured how many of each it would take for the requisite amount in each 2.1 gallon tank, and this has been the best year so far for mineral buildup. The warnings on some of the other products really do give one pause, but I'll probably never forget the few months last winter that I tried what proved to be more-odoriferous-than-I-can-stand tea tree oil instead of this product since I'm reminded at the kitchen sink every time the odor floats out of the empty tanks during refilling. So I suppose it has permanently embedded itself in the tanks' plastic. So when all is said and done, this product still works the best.
