Good ozone producer that doesn't require separate heat sink

This is as advertised. Product was shipped from China, so took a few days for delivery. The one high voltage lead was prewired with small spring leads and is inserted into the center of the tube. The second lead is attached to the ground which also serves as the heat sink. Simply connect to an aquarium pump using ozone tubing such as Norprene. This is rated as 3000 mg/hr so ensure that you are running this through water or metal housing. Much cheaper to build your own ozone machine as opposed to buying one. I'd didn't try to run the power supply through a variable supply, but presumably you can do so to control ozone production.  Excellent source for water purification or cleansing smells from a room

The triple burner Mr. Heater delivers excellent heat. It lights easy, but a electronic ignition would be nice. Gas usage is close to the specs listed. My only complaint like one of the other reviewers listed, some of the burners will shut off sometimes for no reason on low heat. Maybe i just need to adjust the thermocouples.

This ozone generator worked for me. Some reviewers complained about the timer - mine worked ok. One treatment was good enough for a tiny bathroom. I did multiple treatments for a large bedroom with a 50+ year old wool rug; the odor seems to be gone now. This ozone generator is small but not a toy. Follow the safty instructions carefully.  Ozone can be irratating. Though I may not use up the 5000 hour life span of the generator plate, I wish the instruction book specified the replacement part number for the plate and had a picture of it.

Heats up fast and maintains temperature well.  Removable heating element is great, as particles settle below the heat and don't get burnt, helping to preserve the oil quality. Big enough for 3 of us; besides, any bigger and the gallon jug of oil wouldn't be enough to fill it!  (Actually it only used about 3 quarts to fill it to Max - but good oil is not cheap!) Magnetic cord attachment adds a bit of safety with easy release.  Nothing fancy or digital, just a good solid thermostat dial and indicator light.  I suspect this thing will last.  And yes, you can reuse the oil several times.

 When it cools (and it takes a while), pour it slowly back into your storage container, leaving the sludge layer out.  I filtered it through cheesecloth the first time, but I noticed that by the time the oil cools, the particles have settled, and not much was filtered out, so I stopped filtering it.  Instead, I just pour it slowly and leave the particle sludge behind. The oil darkens with every use, but sources say that oil gets better with use before it starts to break down.  Of course, I don't use it for donuts after frying fish and onion rings, but having a different store of oil for different things isn't too bad.

I've been eyeing ozone producing machines for years and liked them a lot, but just could never seem to justify spending $500 plus on a decent one. When checking them out once again earlier this year, noticed that there were a few new brands costing much less than the units I looked at 10 or more years ago. Took a chance on this brand from this seller and am pretty satisfied. The quality seems to be just about on par w/older better known ones. Many nice features, and the unit is easy to take apart to clean. I liked mine so much I bought another, and after having some minor problems with it and contacting the seller, I was promptly shipped a replacement with no hesitation or problems. So GREAT customer service from this seller, and a decent unit at a very good price. My rooms have never smelled fresher. Don't hesitate, get it!

We had an Ozone Purifier for years and it finally gave up. After a lot of research on Amazon Reviews, I decided to buy this one. And disappointed I have been not! It shipped and worked as described. The ozone an ionizer work as expected. I have installed in the kitchen to help remove cooking odors and it does its job magnificently. I have 2 birds very close to the kitchen, so I keep the ozone around 1/2 power and never perceived any issues. It leaves that nice "wet fresh grass" smell you feel after a storm (actually due to the ozone generated by lightning). Would buy again, but hope it will not be the case for many years.

Suggestions for manufacturer:
- Changed the case for a more modern look. Current design looks like a box from the 50'/60's...
- Identify ways to reduce some of the noise (e.g. more efficient and quieter fan).

Although the unit did not come with a pre-filter as shown, I contacted the seller and was told the owners manual is out of date and the unit does not come with a pre-filter. I really don't see the necessity for a pre-filter and the back cover acts as one anyway and will help keep hair, etc from getting in the unit. The spare fuse is located in the fuse holder. For the money it has all the features: a TRUE HEPA filter for dust, skin cells, dust mites and other small particles; a charcoal/carbon filter for odors; a UV light that works with the Photocatalyst filter to kill virus and bacteria; Ionization to clean the air and an adjustable ozone (to "Shock" the air and clean it) that has a higher output than others in it's price range. Seller Warranty: 3 Years.

I have very bad allergies and after running this one night in my small bedroom, I could tell a big difference in the way I felt the next day. DO NOT RUN THE OZONE WHILE YOU OR ANY PETS ARE IN THE ROOM! The ozone is for "Shocking" an area that is unoccupied and should be left unoccupied until the smell of the ozone is gone.

I wanted a unit with the ozone built in because when I worked as a project manager for an insurance restoration firm, that is what we used to remove the smoke odor from houses/furniture etc that had been in a fire. It doesn't mask the odor, it actually cleans the air. Also, this unit comes with a true HEPA filter (not a HEPA TYPE or HEPA LIKE filter). A HEPA filter is one step we used to filter/clean the air when working on mold jobs.

My two car garage had a strong musty smell from the grass on the lawnmower, cat litter boxes, garbage cans etc. I put it in the garage and shocked it on high for about two hours. It took about two more hours for the odor of the ozone to leave. Afterwards, there was no odor at all in the garage, just a clean smell. I have very bad grass/mold allergies and probably cat/pet dander allergies. After using this unit to shock the garage and clean the air in my room, I feel much better and my sense of smell is heightened when I go outside. I run the unit on low/medium 24/7 (NOT ON OZONE) in my small bedroom now and it has really made a difference.

The ozone has a separate knob to turn it on/off and it's own indicator light to let you know when it's on.

I contacted the seller about replacement filters and UV light. The filters run $25 for the entire set of all filters, and UV light is $10.

I have owned my unit for 4 summers now. I live in a small apartment and only needed localized cooling.
It is placed by my couch with a fan behind it. Between the two, it cools my small living room area well.

I cannot put a window AC into my apt. so this is a great option and much cheaper on my electric bill.
It is very lightweight so I can store it easily during the winter months.

Because I have dogs so I change the filter every year.

I like the noise it makes. It serves as a "white noise" against my noisy neighbors.

Would I prefer central AC? Oh yes but this is cheaper and convenient.

 I have a water pitcher to fill the water tank daily and it goes all day long. I live in a dry climate
so evaporative cooling does work well.

I've had no trouble with the "beeping'. But the well does need to be filled every day if you are using
it most of the day.

Bought this product from the manufacturer direct since it was unavailable from Amazon.com. Here are my impressions:
-easy to install within 20 minutes with a pencil, level, drill, screw driver, superglue (for screw covers)
-not rated for bathroom or similar environment which was my plan for a second unit.
-works good as a secondary heat source for a cold area in a 12'x15' sized room with insulated walls, one 5x6 feet window and 8' ceiling.
-at the recommended 100 sq feet of coverage by Econo Heat as the primary heat source, it is too optimistic.
-might work adequately in a 50 sq feet area as a primary heat source as long as the room is well insulated with minimal heat loss from windows/doors etc.
-moderately hot to touch without burning.
-my dogs learned not get too close to it for warmth.
Overall, an adequate addition as a secondary heat source to warm up a cold spot in the room.

I've been using the NewAir AH-450B for about a month and it meets my expectations. Upon unpacking, I was skeptical how effective it would be due to the thin-ness of the fins.  This isn't a bulky unit like other oil filled heaters; there doesn't seem to be much oil inside to heat.  However, it does kick out a good amount of heat and makes my unheated family room comfortable. I guess it's all in the engineering.  To avoid unpleasant smells, before first use run the unit outside on high for a few hours to burn off whatever seems to be coating the unit from the factory. The unit made some crackling sounds the first few uses but they disappeared over time. The thermostat and heat control works well. Be aware that it does draw some amperage so avoid using on electrical circuits with other high amp appliances like microwaves or vacuums.  Overall, I'm pleased with the product.

I LOVE that this unit does not apply heat, which disturbs the integrity of the oils. It's easy to clean, quiet enough (though not silent, as heat-applying diffusers are) and puts out a nice gentle mist that's perfect. I'm not a fan of the colors, but it has a "no light" function, so I keep that turned off.  I debated giving it only 4 stars... I would love if they had an option for a matching top and forewent the tacky plastic top for the light display.

Thanks for the Ozone Generator. Compact and very efficient.
This is a great product.

A real cheap, free, energy sourcing output that 'lights' our lives that too without any environmental impact

I used ozone years ago, when the technology was much more expensive.. But that was a good 15 years ago. But now, that is pretty cheap( like this unit), I tried my hand at a battery-powered/rechargeable that is popular on Amazon,for in my car. I was so impressed with the quality, that I ordered this for our home.. I really didn't expect it to be as strong as it really is. I can't see is running it more than, at the max 30 minutes. I turned it on, turned around and before I could walk out of my kitchen, I was smelling ozone (that fresh scent), and it was strong! Less than 5 minutes later, I came back inside(I only turned the knob to make the unit turn on, and not all the way to 20 minutes), and the complete lower level of our home smelled like ozone. I opened the front and rear doors to vent, and now, throughout our home, it smells fresh.. All from less than 5 minutes of running..

I am truly impressed!

I just bought this heater from elsewhere to heat my 1200 sq/ft double-poly greenhouse. We're supposed to get a good storm over the next few days and I have seeds germinating. My calculations suggested I get a 120,000-140,000 BTU heater and I bought one of those too but it won't be delivered in time so I picked up this smaller unit just in case. Right now, it's 44 F outside and dropping with nighttime lows expected in the mid 30's. I fired up this heater on #2 diesel and it lit on the first try with only a little puff of smoke. It's now 69 F (up from 51) in the greenhouse after an hour of running and it's still climbing. I also bought a smoke detector and CO alarm. The puff of smoke when it started up set off the smoke alarm but that's no big deal. At least I know that thing works too. There's only one thing lacking and that's a thermostat. You can't use an in-line thermostat because this unit must go through a cool-down cycle when you turn it off (without being unplugged). I still think there's a way to incorporate one with a temperature probe, micro controller and relay wired at the regular on/off switch. That should allow the unit to switch off at the desired temp and still go through its cool-down cycle.

Perfect pump for organic chemists who don't like dumping tons of water down the drain whilst using condensers and re-flux apparatuses and like better temperature control.  Provides a constant manageable flow from the coolant sump to the glassware.  Thus far I have not tried using it in a brine solution since most experiments do not required coolant below 0C.
