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

Works great!

I use a small amount of this bacteriolysis in my humidifier. That way it doesn’t smell bad. Also the filter lasts longer when you use this regularly.

I purchased this product to prevent mold and to prolong the life of the filters in my swamp coolers. I have a smaller desk-top Artic Air cooler and a larger floor model swamp cooler. I have used this product faithfully from when the coolers were purchased new. I do believe that it controls mold, and in that regard I am happy. I don't really smell much of a scent though. I suppose if you are sensitive to perfumes, that's probably a good thing. I didn't really buy it because I wanted to scent up the room, so it doesn't really matter to me. If you are hoping that it would have a scent, you might be disappointed. I am also not convinced that it does much regard preventing calcium deposits on the filter. I notice that after just 3 months of use my filter did have deposits on it. It was not a lot, but enough to make me want to soak it in vinegar water before the next warm season begins. It probably matters too what kind of water you use. I was using city water and I think most humidifiers will tell you to use distilled water if at all possible. Swamp coolers go through too much water for me to do that. I was a little disappointed about the deposits. I would still buy it again though because I do believe that it prolongs the life of water filters and that it does prevent mold as promised. No complaints here.

I used to put a teaspoon or so of bleach in each gallon of water for humidification but it made the filters harden and not let the water soak the filter. I get longer use of a filter buy 2 months using this additive. No smell from the water or need to rinse out the water sump.

Good for humidifier

Works well but got a little,carried away ordered 4 still havent used all of the first bottle so wont be ordering any for a few more years.

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

Just what we needed and delivered promptly.Thank you Amazon.
