PUREFY Ultrasonic & Evaporative Humidifier Treatment

I’ve used this additive for an about 2 months and just ordered another bottle. It is affective at preventing mold but I still get some scale in my ultrasonic humidifier.
They recommend 2 oz. per gallon (assuming they mean fl oz that’s 1/4 cup). I usually use about 3 tablespoons in my humidifier that holds just under a gallon. When using it at the recommended concentration, there is a little smell if you’re near the humidifier.
Overall I would recommend but it is a little pricey. I need to clean my humidifier about every 2 weeks instead of every few days.

This basically seems like a Hypochlorous acid-based humidifier treatment. If you look that up on any popular web search engine, you’ll see that it’s a disinfectant used for everything from cleaning surfaces in the restaurant industry to “fogging” office buildings in order to disinfect them. I don’t believe the strength of the hypochlorous acid solution is listed, but they have nailed a product that works well for humidifiers – I’ve tried using other hypochlorous acid 500ppm products in my humidifier but they seem to aggravate my lungs (and also, leave a stronger smell) – this stuff doesn’t. That could just be because it’s at the perfect strength for humidifiers. You can *make* your own hypochlorous acid solution at home using a generator system – again, you can just do a web or Amazon search for various types – and that probably would work as well. From what I have read this stuff is basically the safest disinfectant that you can use that actually works. You can’t use chemical based things like “Golden solution” in ultrasonic humidifiers but you can do exactly that with this.

Could I dilute the 500ppm Hypochlorous acid solutions more or make my own for less money? Possibly, but this product works, it works very well, and the only thing that I have used that seemed to be as effective and non-irritating as this are colloidal silver solutions sold for humidifier disinfecting, and they are quite a bit more expensive to use.

Purefy-life also sells this product at what I believe is a higher concentration of “active ingredient” (Hypochlorous acid) for “large size humidifiers” but the only difference I can see is that this is 2oz per gallon of water and the other is 1oz per gallon of water, so that is another way to save a little on the purchase price.

It’s *dry* where I live usually, and humidifiers are a must for personal comfort. I can’t imagine going back to having to clean and disinfect my humidifiers every 24-48 hours which I used to have to do in order to prevent “red bacteria” growth and general nastiness. Very effective and seems quite shelf stable for a hypochlorous acid product, though there doesn’t seem to be an expiration date on the bottle. I generally use the stuff within a month or two of purchase.

Five stars for working well until something better comes along that I can safely breathe in mist form!

Excellent product, fast service, well-packaged. I have used this product for 5 years. It has all but eliminated the need to clean the humidifiers, and there is never any white water-deposit dust in the house. My only suggestion for improvement would be to include a small measuring cup with the treatment jug.

it’s a shock to my senses that I do not — not even once — have to clean my humidifier since using Purefy. Clorox, vinegar, etc., are things of the past. I use Purefy ever time I fill my humidifier, but at first, I was not convinced this would work. I wanted to use it with every fill so there would be no error in my review. So far (and I just started using my second container of Purefy), there is nothing I can see that requires cleaning. Also, no smell to Purefy or to the output of my humidifier. Yes, it is a bit pricey, but when I consider not spending my senior years cleaning the humidifier, I’m okay with the cost.
