MELEDEN 2019 Portable Ozone Generator Purifier，Multipurpose Fresh Ozone Purifier

Expected the 500mg/h that was on the store yet got a 600mg/h on the item's label. Discrepancy is kind of weird.As soon as you turn it on, you can tell that it's outputting ozone by the fresh smell. Covers my entire apartment within 20 minutes of turning it on and can be set to run up to an hour. Pretty noisy though and I had to put a soft blanket to tone down the vibration and noise this thing produces.My unit arrived with a display that doesn't show the top line for each numerical digit.

Bought in Feb 2020. It is June 3rd and no longer works. Used about 2-3 times a week to disinfect and clean produce. No longer produces ozone. Easy to use and works great - until it doesn’t.

The air purifier feels good, it really works, it refreshes the air, especially the smell of secondhand smoke, it's great.White appearance looks very simple and generous, is my favorite type.It's worth it. It's a great shopping experience.

Did not work out of the box.

It stopped working after a few days. Absolute CRAP :(

Good, easy to use

It is light weight and easy to use. But you have to guess how to use it. 2 stones, one grey and one white. what are there uses? How long to you run it in water? Do you use plastic or glass to purify water? We used glass. How do you purify the air. Would probably be an excellent product if it stated how and how long to use it..

The ozone smell was WAY worse than the odor I was trying to eliminate. Yuck!

I have been using Ozone generator purifier for many years and I believe it can kill the germs on foods, such as fruits and vegetables, especially meat, it can really clean the raw meat! My old one is too big not convenient to use and it's too old so I bought this one. I'm so pleased with it, stylish, compact and does brilliant job. It also helps to eliminate unpleasant smell in the kitchen and bedrooms, which is very useful and It is not loud at all! I will buy one for my dad as well. Highly recommend it, especially at this time!

I don't think it has any guidance on using this machine. Do I need to guess? Any safe precautions needed when using this machine? Do I need to find it online myself?..... unfortunately I can't find.There is Only a piece of paper with a simple specification guide.

Using it to freshen rooms, remove odour and sterilise. Excellent to remove odours, only need to use it for about 10 minutes, but can only trust as to its sterilising properties.No instructions as to what the 2 tubes are for. Slightly noisy when operating.

I’ve been using for purifying water and sterilisation of veggies. I’m happy with it. But lack of info on how to use and for how long to do any thing is a less. As for delivery and packaging a plus.

The thickness of the machine is thin, sheerness is excellent, the value for money is great: it can clean the air in any room quickly, just make sure you open windows after! Very good buy!
