PUREFY Ultrasonic & Evaporative Humidifier - 68 oz Hypoallergenic, Unscented, No Residue, Baby Safe, Auto Cleaning

I have used various products over the years that are supposed to help keep humidifiers clean, so I have some experience in this area. Our current home has a forced hot air system, so humidifying is a must. We bought a 6 gal. unit this year and tried this product to reduce bacteria and slime build up. I find that though this is not inexpensive, it really does work. I have never had a unit stay cleaner than I have with this. So, even with the price, I feel like it is well worth it for the health of the air that we are breathing and to prolong the life of the filters as well as minimize build up without using harsh chemicals. UPDATE: I have now used this product for 3 heating seasons as explained above. I feel that this makes a significant difference in the quality of the moist air being put into our home from the humidifier. I highly recommend this product.

I am shocked at how well this product works at keeping away slime, mold and oder out of my humidifiers. I am so used to cleaning my humidifiers every 2 weeks and still seeing mold and slime even though I used a Bacteriostatic treatment. I would have to change the filters every two weeks also which gets costly. It's been 27 days and the base and tank are squeaky clean and don't smell. The filter is also clean. The only exception with the filter is the top nearest the fan which gets crust dry and dirty from the air but even that is less than I've ever seen it. I'll easily be able to go for a full month or longer without having to take the humidifiers apart and disinfect them. I am really truly amazed with this product and highly recommend it to anyone who uses filtered humidifiers. I honestly don't know how anyone could rate this stuff lower than 5 stars. It's fantastic stuff!!!!

We've been using a new 4-gal ultrasonic humidifier 24/7 for the past 30 days during a very dry winter. We consistently run through 3 gallons of tap water every 24 hrs. I've used only 2 oz of this product with each 3 gallon refill. The two small spots that you can see in the photo is the extent of the buildup inside the unit, which also has a UV light to help keep the water clean. I don't know if this ratio will do the job when the air is less dry and the refill water sits for more than a day, but for our purposes this product works. Deducted one star due to the price and a slight smell the first day when I used 2 oz per gallon. The smell was the reason I cut back in the ratio.

I have well water, with lots of minerals, making it extremely hard to keep it clean. But this product is amazing. Highly recommend it

PROS: > It does the job. > I didn't have to clean the unit after using this product. CONS: > It's riduculously over priced, therefore, not affordable for the winter months in Ohio. > Strongly smellls like bleach.

I have used other similar products however this stuff is great. I’ve noticed it keeps my dry air humidifier water cleaner longer. & I live in an extremely dusty environment.

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!
