Caution using any ozone generator

The verdict is out on whether it helped with the smell of tar and nicotine in my furnace from the previous owner of my home. But before you use an ozone generator, read "Ozone Generator Hazards by Nick Gromicko" (google it on the internet). A true eye-opener. Make up your own mind.

It worked fine for a short time but then began generating ozones, a problem that has become increasingly serious.  It also has a problem of overheating, possibly due arcing inside the body of the knife, which is also the source of the ozones. This seems to be a problem with small electric appliances manufactured in China.  Cuisinart used to manufacture superior products, but this is no longer true.  The knife going into the junk heap and I would urge buyers to look elsewhere for a usable knife.

Do not use this unless you plan on using chlorine it does not produce ozone sufficent to disinfect anything larger than a glass of water. It produces small amounts of ozone with uv light not suitable for a pool

I used this for my new room, and the ozone smell is awful!!!! It did purify the room, but the following day I was starting to feel ill and within a week I got sick from this product. Do not buy.

I'm an avid DIY'er, after much research and reading the reviews on this product I decided to purchase..bad idea.  I followed the directions to the "T" and overcharged my system.  What the manufacturer's don't mention is that when your A/C is running the condenser is cycling off while recharging; this gives a faulty reading to the fill level that's coming from the condenser.  Now what used to be somewhat cool air is warm, there's a chemical smell coming from my A/C vents while it's running, the condenser no longer cycles off which leads me to believe it may be going out or definitely is going to need to be evacuated, and I'm going to be out more money for taking it in for repairs.  If you've done your own recharge before, you should be okay.  If not, beware, have someone with experience teach you before taking the plunge yourself.  Also the pen light that came with the kit did not function.  Wouldn't recommend it.

Loved mine and went to buy a second one, but it will no longer ship to California. I had stopped using the ionizer on it when I learned how harmful ozone gas is, and now it's banned in my state since it's deemed harmful for the environment. Too bad they don't make one without the ionizer.

This is a BIG VOLUME O3 production so PLEASE be careful and learn what you are doing with it!!! Unit is easy to use but manual is a real jonk, no info at all... but you need an Ozone , not a manual :).  I use it after reading a book One Minute Cure and realising the brilliant idea that YES we are breasing Oxygen and can't live without it... I am bubbling ozone through the water and drink it. (water disolves 80% of O3)  While inside  - pure Oxygen get reliased  from O3 (osone) and gets in your body / blood and you fill good and kill all mutated sells in body and infections. I love the machine but please do not brease in pure O3!!! Read and read and learn before use any ozonator.

Just received the UVP-9
9 Watt UV Sterilizing Pump

plugged it in ran fine for 3 days then when I was installing a new heater, I got a huge shock! unplugged the sterilizer, and the water was fine.

Now I know why my GFI was tripping.

Test your water with a meter and be safe.

I purchased a used camper. The previous owners were smokers. My wife and I do not smoke. After using this ozone generator for about 30 days it killed 100%  of the odor. Worth every penny spent!

Works well to remove months of scum on the gelcoat.  But as others have said, use precautions when using this product; protective gloves, eye protection, and even a respirator - the fumes are really bad.
Poured liquid into a 1.25 gallon pump sprayer and just sprayed it on.  Waited a few minutes and washed the hull with a brush and car soap.  Had to repeat on a few areas, but it basically turned my greenish-brown hull, white again!

When I took this item on a hunting trip out of state, the ozone machine would not come on AT ALL.

Purchased this worthless piece of junk as a Christmas gift for my bride to use in our vacation condo (and have since tossed the packaging and receipt), and on its SECOND use, this piece of garbage filled our kitchen with the pungent aroma of ozone while failing to even warm our meal. In all fairness, we purchased this pile from Macys, but no matter the source, we will take special pains to avoid Black & Decker products from this day forward.

This thing almost killed my family...twice. Be extremely careful with this Dyna-Glo 23,000 BTU Portable Kerosene Convection Heater. Twice now when I have gone to shut this heater down the unit has remained lit on an very low level putting out large amounts of carbon monoxide. The first time was when I went to shut it down with the release button from a low level setting. Luckily, I removed the heater to the outside and did not notice until the next morning when I went to start it back up and as soon as I raised the wick the unit fired back up without the igniter being used. I also noticed a bad burn type of smell just before starting. From then on I decided that I would always place the unit outside when not in use. Until a few nights ago anyway. It hadn't happened in a while and I fell asleep at my desk. When I got up to go to bed I got lazy and did not remove the unit. I shut it down and went to bed only to wake up about 4AM to an awful smell in the house. The unit was in a closed off porch that was attached but separate from the main house. That was probably the only thing that saved my life. The unit was again still micro lit and putting off massive amounts of CO. I know that the off trigger was completely depressed when I went to bed so the unit should have been off and cold. What I have discovered since then was that if the unit is at its lowest setting when the off release lever is pushed the wick does not always retract to its lowest setting shutting the heater down. I do not know if this is a problem with my one unit or an engineering flaw with the system. My unit was purchased new one year ago and this should not be placing my family at risk. Be very careful when shutting down this unit. It could be the last thing you ever do!

This little machine works very good produce, a lot of ozone on max setting, it will remove bad odors even bigger rooms such as combined kitchen / living rooms, but don't leave it on max where pets, kids or people sleeps in the area as high concentration of ozone can harm you, I turn my ozone generator on when I leave my house or when the room is not in use , the generator will leave a fresh feeling room for days after the cleaning process.

Clogged up my cloner, did not play well with other chemicals or cloning agents.  Silica hit it and it would have a white cloud effect and turn to snot.

This unit is okay provided you understand correctly what it is. There are a lot of devices that are called "ionizers," and not all of them do the same thing or work in the same way. Allow me to explain:

First and foremost, this product is an ozone generator-- yes, in spite of the fact that it mainly advertises itself as an electrostatic dust collector (which are also referred to as "ionizers," but aren't really the same thing), this is an ozone generator. If you open it up like I did, you will find that this is a pretty standard "corona discharge"-type ozone generator (see attached image for an internal view). It uses needles and sharp points of metal  spaced near a metal grid plate to create a very small area of electrical corona at the tips of the sharp points (if you look into the front of the unit while it is running in a dark room, you will notice four tiny dots of purple light-- this is the electrical corona). This works by applying a high voltage to sharp metal needles that are near a metal plate.

Corona discharge produces a significant amount of ozone, and although it also has the advertised secondary effect of attracting SOME dust from the high voltages on the needles, that isn't really its primary function. Running this unit for even a few minutes produces a noticeable ozone smell in the room. This is not like your typical electrostatic dust filter ionizers (the kind with the flat plates that you have to wipe off), which produces extremely little ozone in normal operation, are are mainly used to attract dust.

Keep in mind, ozone generators are considered by some to be useful for getting rid of smells, but ozone is generally an unwanted side-effect if you are just trying to trap dust or other particles in the air. Generating too much ozone can be bad for your health, so I would recommend not using this in overly small rooms or a car, or if you have asthma. As an experiment (I don't have asthma), I left this running in a small bedroom, and I woke up the next morning with an irritated nose and throat from all the ozone it produced. I occasionally run this unit in my kitchen. I leave it running while I am away at work, but then I immediately unplug it when I get home.
