We have an opportunity to try selling these. It's supposed to "add enhanced oxidation and photo-catalytic oxidizers to the cold water supply". It's supposed to use the same tech that commercial systems use. Eliminates or minimizes the need for laundry additives or detergents.

Has anyone used this product and have any reviews? We are going to hook one up here at the shop and try it for ourselves both on HE and conventional machines before carrying it to sell...

"Does this sound too good to be true?"

Yes... Ozonation of water could provide cleaning benefits, somehow I doubt that complete replacement of detergent is one of them. As always multiply all claims made by someone trying to sell you something by ~.25

I have experimented with ozone generators to increase free oxygen in water based synthetic machine tool coolants to kill off anaerobic bacteria that tends to grow in the sump. Nowhere in their brochure or in the videos did they state how much power this device draws so its hard to determine the amount of ozone it generates. Can it produce ozone at a high enough rate to really change the water much at normal fill rates?

It would be very interesting to actually do some analysis of the water that comes from the device. At the very least, draw off a glass of water from this device when you get it running, see if you can detect the acrid scent of ozone coming out of solution.

I'd think that perhaps this could augment cleaning, much like adding an oxygen bleach would. My guess is that I don't think P&G is nervous that this device will put them out of the detergent business.

The video says it uses 20 watts

This would be a neat device for those refusing to wash in anything but cold water. Might help with mold/mildew problems that are so common in the US with front load washers. I was expecting it to be like $150, MAYBE $200 and it might be worth it should it prove to actually help with disinfecting and possibly reducing detergent consumption, but $450? Not a chance.

I do recall a video on yt of oxygenated water being used in commercial environments. But this is just too expensive for the risk.

Low voltage power supply? Must be for the light bulb inside!!! Looks like a joke to me. Pricey too!

"Mirage"? As in something that isn't really there but you want to believe it is?

Low voltage power supply?

kb0nes's profile picture
Most ozone generators use a high voltage corona discharge device to create ozone by pumping air through a high voltage electrical field. Some use a UV lamp but the ozone generation is much lower with that method.

Many small volume devices like this use a stock off the shelf "wall wart" low voltage supply like this because the power supply maker has already got UL and other approvals. This saves the equipment maker the expense of getting their device and its power supply approved for sale. They could, and likely do, use a DC-DC converter inside their device to take the low voltage up to a high voltage for the corona discharge device. May not be the most efficient way to do things but is saves expense as submitting for UL or TUV etc approval is quite costly.

Still curious as to how much this would help out cleaning in the washer though!

Similar to what's used in commercial applications; minimizes or eliminates need for detergents and other additives? Here's my question: Don't commercial applications use detergent and other additives even if they have an industrial-strength version of the PureWash device?

Aside: Were I naming a company that sells new products I would think twice about calling it "Mirage".

Weren't these a part of some multi-level marketing scheme some time ago?

I had to bring this back up because the radio show I listen to talks about this ALL the time. He says how skeptical was and still is but it really works. He even purposely stained something to see if it would come clean. They talked about this for 2 hours and it was very interesting. I read reviews on Amazon and they are all great.......But you HAVE to use COLD water only. Apparently Ozone works better in cold......I wonder how it would work with machines that add warm to cold to keep cold from being too cold? Some are thinking this will eventually be built into washers.

Still no thanks. Does it remove the grease from your clothes like cold water fails at so badly? Does it sanitise your skidded pants? I dont think so: Be interesting fo test that though. But I must say, since we started using f our Miele last year with warm and hot washes, none of us have been sick with colds or the like, something that was a huge problem before that with cold only

Friends in FL had a well and used ozone to treat the water instead of chlorination. The water smelled OK, but was very hard. One thing that did not work was some sort of anode they bought instead of a water softener. They finally had to install a softener.

I think it does

mark_wpduet's profile picture
sanitize everything but it actually needs cold water to do it..the warmer the water the less effective.....

I dunno

I too can't get past the grossness of trying to wash clothes without detergent or hot water, but I like to keep somewhat of an open mind.

Intrigueing is that there are two models. A high flow system for toploaders and a low flow system for frontloaders. I wonder if there is anything different between those two. Open them both up and if there is no difference, they're a scam.

I resurected this thread, because:

iheartmaytag's profile picture

I had been reading about the Laundry Pure system that was supposed to save all this money from not buying detergent, plus  you wash in cold water.


As other's had stated in the original thread, I was skeptical.   I found several professional reviews online, including  Good Housekeeping.  I tended to discount the user reviews found online in places like Amazon, as many of the users were singing praises more to justify their purchase, than actual results, or were professional reviewers that were posting what the companies paid them to post.


Good  Housekeeping  review stated what we had already hypothesized.  "The system performed no better than the control group washed in plain water."  "While it did remove odors, it was not as good as when detergent was used. "


Other professional reviews state "Laundry Pro, Bogus"  "Pure-Wash lacks cleaning ability"  "WashIT, didn't cut it."


My verdict:  Save your money to heat water and buy detergent.
