Hi its Craig here, welcome to our Ozone generators review page.  
If you are looking for the best Ozone Generators for odor removal, mold removal smoke odor, and cleaning purposes then you are in the right place.  We advise commercial Ozone operators and domestic customers on which Ozone purifier will work the best for you.

I also advise on ozone shock treatments for urine spillage, smoke contamination, mold treatment, odor caused by decay, rot and stale rooms.

Our review of the Enerzen Commercial Ozone Generator

Summary

We own 5 of these machines and have had them for a over 5 years now. We purchased these to do interior ozone shock treatments in cars, houses, basements and pet facilities. We find them more reliable than UV ozone machines, and extremely inexpensive. 
The machinery will do a whole house (good amount of o3 output) if you move it room to room (make sure you let the gas dissipate first) or you can leave it in a central position and  for 24 hours with airflow generation done with fans . Great for sanitizing dander also. The Mammoth purifier is a powerful little unit and the Ozone Pump is strong enough to penetrate into the far reaches of a whole house.
The first thing that impressed us about these machines is the solid manufacturing and the amount of small bolts firmly holding the machine together. Some other Ozone machines we have used are very poorly constructed and do not have enough fastenings to handle the rugged life a contractor gives it, but not these units. They are very solid.
The unit is lightweight and easy to transport and a sensible size for storing away and placing in the work vehicle.
Size: 6.75″(H) x 8″(W) x 5.75″(D)
The generator weighs about 5 pounds and comes with US 110 voltage and 55 watts of power for the generator. It uses Corona discharge method of generating ozone which means less maintenance and all in all these are incredible value for the price.  The corona discharge means  no copper lining and no UV bulbs to break. But at the price of these ozone machines its not a concern as they last for years any way. We have found the slide connectors inside the units to be quite thin however this also is not a big concern and very cheap to replace if required. The  Commercial Ozone Generator has a powerful 5000 mgs/per hour of output, and a very useful timer with max setting of 2 hours. You can run the machine on “continual” and turn on and off manually. This is very helpful when using the machine for Ozone Shock Treatments such as getting rid of cigarette smoke smell in car .
The machine is well constructed and very good value for money.
Over all we love this machine and for the price you won’t beat it.

No 2: Ozone Airthereal Commercial Air Ozone Generator 5000mg

(Revised 2019 to 4 star)   

Our review of the Ozone Power Airtherea Commercial Air Ozone Generator  REVISED 2019

Incredible Output of Ozone at 5000mg Per hour.
This was the machine we used when more Ozone is required. This Ozone Generator Machine has 5000mgs per hour of Ozone output (high) which is good for air contaminants and with a 5 year warranty you would think this must be the best value on the net however lately issues developed with the workmanship and some of the internal parts on this unit and the reliability is now not great.

It also led to testing the 5 year warranty and this being a return to base warranty meant most people can not ship it as the postage is too prohibitive.

It is still well priced however and the unit has excellent ozone output when it does work.

Feedback has been that after 3-4 months of use, the machine parts fail and it is dead. If you are happy to proceed and accept that the life span will be short then this unit has the timer like the  Ozone Generator ozone power op5000 and was of solid construction like the Mammoth, (but as pointed out above it now seems some of the parts are only lasting 4-5 months).

The unit is bigger, was better constructed and more powerful (does up to 5000 square feet) and for a humble $25-00 more than the Mammoth it makes perfect sense if you need a more powerful unit. The downside is the life expectancy of the unit and the return to base warranty which means you have to ship it back the manufacturer in Canada to get it repaired and that freight for most people shipping the Ozone machine will cost more than buying it.

The Airthereal is named due to the 5000mgs per hour of Ozone Output. For a heavy duty Ozone generator we feel this is could be improved. 

The machine is slightly heavier at 6 pounds which is caused by the a heavier outside metal casing. Size: 9 x 9 x 7 inches. It comes with US 110 voltage and 55 watts of power for the generator. The OP5000 is very well constructed using solid 3mm metal casing and it uses the Corona discharge method of generating ozone which means less maintenance (unlike ultraviolet filtration) and all in all these add up to incredible value for the price when it is working.

The Ozone Power OP5000 Commercial Air Ozone Generator & Air Purifier has an even more powerful 5000 mgs/ per hour of Ozone output which is suited for larger areas and stronger odor contaminations such as cooking smells inside a house, or strong mold odors in a basement area or garage. This unit also has the very handy timers or you can run it continuously as well. These types of units when we first started in 2002 were over $1000 . Not any more, at the price point the ozone machine sells for we say good value and great for air contaminants.

We used to recommend the enerzen commercial ozone generator but the enerzen commercial is no longer available. As far as air purification products go this one is ok. Beats a lamp system anyday!

Our review of the Odorstop 2500 Ozone Generator Another great unit from the Odorstop Stable and this one caught our eye due to the ease of servicing the Corona Discharge Plates and the ability to buy spares as shown below, The parts are easy to install and are very well priced.

• Price: This unit is dearer than the others and the reason for this is it’s a commercial grade machine with the ability to service and replace parts. It is also a silent ozone machine. Most Ozone machines use a Corona Discharge Method where a current is passed between metal plates and the air passing through is oxidized and turns into O3 gas. The plates get build up on them of contaminants and this can affect the Ozone Gas Output. Service as at 2019 is good
  This machine allows you to easily remove the Metal Ozonator Plates and replace them inexpensively with new ones thus making the unit last for years. The commercial operators or landlords will be interested in this unit as it will last longer than the cheaper ones due to the ability to be serviced and have the Ozone parts and plates replaced. We think for some one working in a business using this machine, this is essential.
• Design: The machine also has an air inlet filter (albeit thin) but at least it is something to try to keep the dust out. The units are quite pricey but for a commercial operator these come highly recommended for the ability to replace the ceramic plates. With Ozone machines you have two choices really. Buy something cheaper like the Mammoth and when it fails throw it away or invest more and get a commercial unit like this one and service it to make it last for 10 years or more. The machines are well constructed, solidly built and  weighing in at 9.5 pounds she is quite heavy, but if you are a commercial guy weight is good!. It means the machine will be well constructed and have solid parts which is what we need for durability. Odorstop also do a great range of blowers as well as ozone machines Click here for more information
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   

No 4: Green Air Ozone Generator Alpine Air Purifier

Our Review of The Green Air Purifiers Green Air Classic Plus Alpine Air Purifier Ozone Generator.

The Green Air Purifiers Commercial Ozone Generator and Air Purifier has a powerful 3500 mgs/per hour of output and has the distinct advantage of having washable carbon filters at the air input area to prevent the machine from sucking in debris and dust particles but we feel the extra price and clunky packaging makes this unit not as desirable for commercial operators. The filter makes the machine last longer and guarantees the output of Ozone is not affected by dirty corona discharge plates . Having no dust entering the air inlet means the ozone output should always be as rated, there won’t be a requirement for servicing and cleaning the inside, where as the cheaper units that do not have filters, need the production units cleaned to ensure the ozone output is maintained. Typically the fan gets coated in dust particles and allergens. The ozonator has a nice electronic control panel for operating the machine and easy to follow controls . The body however although its well built is very impracticable for commercial use without handles and a wooden styled outer that is scratched easily.

No 5: A2Z Ozone MP 8000 Ozone Generator

This is very handy for doing larger areas

Our review of the A2Z Ozone MP 8000 Ozone Generator

Summary

This is just one of the commercial ozone machines from the “stable” from A2Z. We have been very impressed by the quality of their units and we love these machines as they have some features that the other commercial machines lack which make them very versatile for the applications they can provide. A2Z are targeting the commercial operators.

For example the most noticeable feature is the ability to add an Oxygen Generator to the unit, which in turn will boost the ozone output to very high levels plus remove the Nitric Oxide Component of the O3 gas. The machine also has a external vent to allow a hose to be attached and run into the treatment areas i.e the hose into the room with odor issues. This is very handy for doing larger areas where the source of the Ozone, i.e the machine is located outside of the treatment areas thus allowing clean air input with no contaminants to jeopardize the quality of the Ozone gas or the machine internal components being damaged by the actual gas itself. Ozone cleaner is part of the system.

The unit has a very efficient internal pump to push the ozone out if you are not using the Oxygen Generator Option and we feel for the money the pump could be a little bit more powerful however as alot of the commercial operators know, A cheap fan on the floor will push the ozone gas around very well regardless.
These Ozone machines are the real deal and we are impressed by the range put out by A2Z so far. Click here for more information

Hi Craig The Odor Dude here.
A regular question we get at the Odor Dude headquarters is how to clean dog poop off concrete and more importantly how to doggie doo dissolver in a yard.
Dog poo or dog poop can be very annoying at the best of times, and not everybody likes to pick up the feces with their plastic bag or a spade and want instead a way to make it dissolve and vanish. Here are a few options. 

Hi Craig The Odor Dude Here,
Welcome to my site and please feel free to ask any questions.

How to get cat pee out of car seat

We have all done it at some stage, i.e place a nervous cat in a vehicle.
We rush off to the vet or on holiday, forgetting that cats don’t travel in cars every day so they tend to get nervous. End result is the cat pees inside the car and sometimes we don’t notice in all the rush!

Then a few weeks later that horrible cat urine odor starts to emerge and because the urine goes in deep, the odor can be around for many years to come.  Fortunately we come across this issue regularly and have a simple solution for you below, even if the cat urine is old.

Solution: Make your own cat urine neutralizer using Craig the Odor Dudes formulation and apply to the car seat

How to remove Cat urine from a car seat. (also Dog urine).

Step One. Identify the main contamination area

Hopefully you know where the cat peed so you don’t have to do this important but unappealing process.
The best way to find cat urine is by  sniffing the area with your nose, which is a reliable but kinda gross for alot of people.
A more effective way is to mix up some of our cat urine remover and spray it onto the seat which you can see in below.

Step Two: Mix up the odor remover as per recipe inside members area.

Make the product as shown inside the members area and have ready in a bucket beside you. 

Step Three: Treat The area with a heavy dose of (approx 1 pint)

Apply a heavy application ensuring the product penetrates deep into the fabric and seat. Mix up 1 quart of Formula One (Use Formula two if the urine is older than 2 weeks) and spray a very heavy application onto the area. Ensure you have towels underneath the seat to catch the residues. This saves having a wet floor as well as wet seats.
Check on progress as you go along. Smell the area you just treated. If you can still smell cat urine then reapply the product and repeat the treatment. Usually 2 applications will be the maximum you will need to do.

Step Four: Leave the product to soak in for approximately 15 minutes minimum

Once it has soaked in dry the top of the seat with towels and leave the car in the sun with the windows down 1/4 inch. Test the odor when dry and re-apply if necessary.
 Awesome product and highly effective on cat urine in a car seat and carpet.

TIP: (IF YOU DO NOT KNOW WHERE THE CAT URINATED)

Put the Home Made Cat urine Odor Killer into a spray bottle and spray onto the carpet and cat seat area and look for white foaming as shown below.
The white foaming on the seat shows exactly where the cat urine odor is located.

Step Five Remove the chemical and urine residues

Use a dry towel folded in half as below and push firmly on the seat to absorb some of the cleaning product.  Thats it you are done. Leave the window open slightly and leave to dry.

There are several products on the market that are very good to use and we show those below however in 2002 Craig  developed our own product using four easy to buy ingredients.This was due to doing alot of odor removal and we needed something a bit more economical to use. We did hundreds of hours of tweaking and testing and perfected our formulation on dog pee odor . You can buy the formula here. Thousands of pet owners all around the world have used our homemade recipe successfully.

What to do if the smell persists

Ozone is very effective for  cat urine odor removal and will boost the whole process plus sterilize your vehicle.

Best Cat Urine Odor Remover  Method.

Hi Craig The Odor Dude Here.
If you have the misfortune to have a sewer smell in house, shower drain smells or a sewer smell in the bathroom and you are concerned at the terrible odor and potential health problems associated with sewer gas smell in bathroom or elsewhere, then do not fear as we have all the solutions for you listed below.

No 1. How to remove raw sewage outside

Unfortunately from time to time a sewer pipe breaks under the soil, and then feces and other waste seeps into the yard.
All the jobs we have been called out to, have had the sewer pipe repaired by a plumbers but most of them, do not know how to deal with the odor and the sewage waste remaining in the area.

Simple Solution for outside Sewage Seepage
If the sewage has seeped into the OUTSIDE living spaces, or under your house, then a simple solution is to cover the area in HYDRATED LIME.  Lime is a corrosive material and should be handled with care.

Lime will consume the waste matter very quickly and then break down residues and become one with the soil. It also removes the odor instantly which is handy if the odor is getting inside the house and  if the house smells like sewage also.
WARNING KEEP ANIMALS OFF AND CHILDREN as lime is very corrosive and will damage those that come in contact with it.
You need to cordon the area off and put signs up with WARNING HYDRATED LIME PRESENT. DO NOT ENTER.
The lime will break down the feces very quickly and remove the odor.
Do not inhale Lime and pellets although more expensive can be easier to handle in confined spaces.
Click the image below for more details on where to buy the correct type of lime.

DO NOT USE INSIDE ONLY OUTSIDE!!!.

No 2. How to get rid of spilled sewerage inside the house

If you have a flood in the toilet and you get some waste inside the house on the floor then listed below are two options to deal with sanitizing the area.

Step No 1. Wear protective eye wear, heavy rubber gloves and protect your skin with an coverall suit.
Step No 2. Remove any solids and dispose of correctly
Step No 3: Apply a good application of my DIY Formula two product. More information here

Simple mix it up as shown and apply to the floor area. (It foams white when working as shown below)

My formula working on feces and urine waste.

Step No Five. Clean any residues with warm water

How to get rid of sulphur smells coming from a shower and in the bathroom.

Sulfur smells in your bathroom are generally caused by bacteria trapped in the drain and because no oxygen is present the sulphur smell keeps increasing. The best way to treat this is pour some of my formula down the drain and then wait for it to work.

How to remove sulfur smell from a drain

This is similar to the above situation. There are a few suggestions to get rid of the odor.
1. If you have access to the waste outlet i.e not the shower drain but the drain waste outside then you can pour my formula into the drain which will kill the bacteria and remove the smell. Ensure there is no blockage in the pipe such as trapped hair etc which may be preventing the waste water from flowing through. Tip the formula down the shower drain so that it eats anything stuck in the drain on the way down, plus kills the bacteria in the outside waste. This a safer and more effective method.

How to remove poo and sewer odor when camping out.

Here is a trade secret on how you can keep the odor down. You can also use HYDRATED LIME when camping for your in ground toilet (Long Drop). Never remove the air supply as dangerous gases will build up if no air can penetrate but Lime will eat all the feces and remove odors very quickly.

They are favored by people camping out for a few weeks or as in the case above when the sewer is damaged by an earthquake. Basically you dig a very deep hole with a post hole borer and then place a toilet above it as shown.

How to remove the odor without Lime

Step No 1
Have a large fire going (you have these when you are camping anyway right?)

Step No 2
When the fire has died down grab a bucket of ashes onto a metal spade and tip these down the long drop hole (preferred when they are not red hot as you may cause damage to the toilet seats or surrounding structure)

Step No 3
Go and have a beer and enjoy the toilet next time you use it as the odor will be totally gone guaranteed.

Hi its Craig here and welcome to our reviews of the best Carpet Drying Fan Blowers. We have noticed over the years that alot of our web traffic are commercial carpet cleaners looking for help with choosing Ozone Machines  and other associated products such as Carpet Air Moving Fans and Blowers. We review here the best commercial carpet drying fan based on our own experiences with carpet cleaning and odor removal. Having a reliable air mover not only assist with Ozone distribution during odor removal treatments but also when carpets are cleaned and need to be dried or if a flood has occurred and excess water needs to be air dried also. So as you can see the carpet drying fan or blower as they are called is a useful price of equipment to have if you are a commercial operator or if you are a home owner or landlord. Its always useful to read several carpet blower reviews before purchasing and get a unbiased view on what is good and what is not good. We list our opinions and findings below and we hope you enjoy our machine reviews.

No 1. OdorStop OS2800 Commercial Carpet Dryer 3 Speed fan

Our review of the Odorstop OS2800 Air Mover

Its no doubt these guys are out to impress and take the quality and durability of their floor dryer very seriously. Over the years we have used a number of carpet dryers and the machines varied in quality and price. Its fair to say the price has come down since 2000 as alot of the units are now made in China however the quality on some of them is terrible. Not with Odorstop, these are tough and work brilliantly. With its 3/4HP blower engine the blower can push air out they say to 100 feet. I actually think it is more. The units also can stack

We also love the 30 foot commercial cable (its yellow too!) that gives plenty of coverage and of course the carpet clamp which keeps the carpet above the air when place in the corner of the room or carpet you are drying.

We also are big fans of Odorstops Ozone Machine too

Client Comment : Amazing Machine!…Stronger fan then I thought it would be, 3 fan speeds made it nice for floating the carpet without flapping . Verified Purchaser by Gavin Green.

No 2: Contair FLO800GY Carpet Dryer and Air Blower

We had to include a good, more economical unit in our review for those that  just need a machine for a one off type application or for the commercial people that don’t use the machine on a day to day basis. From this standpoint the Contair is perfect. It is very inexpensive to buy, has a suitable fan for moving air and drying cleaned carpets very well and at the price it is and a one year warranty its a no brainer to buy it. But if you are a commercial operator then we recommend you invest more and buy the OdorStop Unit shown above.

Our review of the Contair FLO800GY Floor Dryer and Air Mover.

REVISED 2017
This is a machine best suited to a one off incident like a laundry flood or for a pushing ozone around in a Ozone Treatment. It is also great for carpet cleaners that want to dry the carpet after a clean. This carpet floor dryer is moderately priced and you definitely get what you pay for but it has a place in the market and has good reviews from the people who purchased it. 
So lets take a look at some of the specification of this air blower and then advise you who it is suitable for.
The air blower is a 1200 CFM (Cubic Feet per Minute( which according to the manufacturers provides 25 Feet of air flow)
If you are a home owner or commercial operator and air drying is not  a big part of your business then this unit is perfect for drying a laundry flood, or Kitchen Flood. It is not however suited for placing in the corner of a room and drying UNDER the carpet. The fan is simply not strong enough to lift the carpet. However you will see by the feedback below people who purchased this carpet floor dryer are very happy with the results it provides. Cheaper units like these can be louder than something more expensive but for most people a fan blower noise is something that is not considered to be a problem.
We used to do a lot of work in a Old Peoples Home and having a quiet machine was critical as a lot of our work was in empty rooms at night after a days treatment of urine and feces in the flooring.  To have a noisy engine kept other residents awake.

• Price: This unit is dearer than the others and the reason for this is it’s a commercial grade machine with the ability to service and replace parts.

No 4: Shop Vac 1032000 Mini Air Blower (Cheap and Cheerful)

Our Review of The Shop-Vac 1032000 Mighty Mini Air Mover.

The Shop-Vac economy unit or Mini as they like to call it has a under powered fan for commercial use  and this machine is most likely suited to someone who just wants to move air within a house. People are buying these because of the price, as in they are really cheap but there is an old saying written in 1824 by John Ruskin that is very true. He said in summary “Its unwise to pay too much but its worse to pay too little” When you pay to much all you lose is money, when you pay to little you sometimes lose everything because the Air Blower you buy can’t do the job you need”  I improvised about the air blower but you get my point.

They have sold 400 of these on Amazon so clearly there is  a need in the market for a cheaper 3 speed air blower, however I can’t see how these would dry carpet with the small fan so in fact they are a glorified house fan made to look like a blower shape to try to tap into the commercial market.

Fro my stand point I would not buy one for our application but you may have a use that they are perfect for.
