Best Ozone Generator – Multipurpose Air Purifier 2020

Last Updated on June 18, 2020 by MakeThingsReal

Who loves bad odor? I mean do you ever look forward to coming home and smelling the fetid whiff of the wind or the smell of a dead mammal or fart or mold? Read no further if you do. The contents of this article would be an affront to your queer delights. But, if you crave the freshness of the winds after the rainfall, worried that the air you are breathing in might not be safe for consumption. Or you’re appalled by and find foul-smelling air or bad odors in general to be a turn-off, then read on my friend, read on.

If you’re like me and live in a coastal region with bad government policies, you will notice the fetid smell in the air due to pollution of the waters. If rodents ever infested your apartment and you applied poison, and now the mammals are dead and rotting. But for the life of you, you can’t determine where the smell is coming from because you know the hassle. This is why ozone generators become much more important.

I’m not here to start another chemistry class. But ozone (O3) is an allotrope of oxygen (O2), notice the 2 in a regular molecule of oxygen is replaced with 3 in the ozone? Yes? No? Okay, moving on, Ozone is a strong oxidizing agent and one of the most powerful disinfectants known all over the world. It’s 3000 times the germ-killing ability of Chlorine. It is also capable of oxidizing smells and bacteria and rendering them odorless. In much more simplified terms, Ozone is that clean, fresh smell in the air after a thunderstorm. And so an ozone generator is a machine that generates ozone for the exclusive purpose of purifying the air. Hence getting rid of unwanted odors. Many ozone generators also kill bacteria and fungus by oxidizing them.

 

WHAT TO LOOK FOR WHEN BUYING AN OZONE GENERATOR

Naturally, a lot of ozone generators abound in the market. But, there are things to look out for before making a decision on the one you want to buy. These include:

i. MODE OF OZONE GENERATION

Ozone generators are classified based on their set up for ozone generation. And the first thing to look for is the manner in which your ozone generator produces its ozone. There are several ways the machine does that, ways which include:

1. Ultraviolet light ozone generators.

   Also called VUV (vacuum ultraviolet) ozone generators. These generators work on the same procedure the sun applies in producing the layer of ozone covering the earth. They use a light source to provide a narrow-band UV light that converts oxygen in contact with it to ozone. While they are less expensive, the concentration of ozone they generate is on the small side.

2. Corona discharge ozone generators.

   The Corona discharge ozone generator is the most common type of ozone generator. It employs the use of a corona discharge tube to generate ozone. The reason behind its popularity is due to its lack of reliance on oxygen as the source of ozone generation, but ambient air. But, fluctuations in ambient air due to environmental or weather conditions may affect its capacity to generate ozone.

3. Electrolytic ozone generators.

   The EOG operates by splitting water molecules into atoms of hydrogen, oxygen, and ozone. Because water is used as its source material, these class of ozone generators works independently of the air quality. This method is usually frowned upon. The production of ozone this way requires an overpotential, i.e., more energy than normal.

4. Cold plasma ozone generators.

   Here, pure oxygen gas is left exposed to a plasma created by dielectric barrier discharge. This splits the molecules of the oxygen into atomic oxygen. The atomic oxygen then recombines in threes to form molecules of ozone. Although they produce more ozone per given time than the UV generators, they are usually less common. As the production of ozone, this way is more expensive than the UV or the Corona discharge method.

Other factors considered during shopping for an ozone generator include:

ii. OZONE PRODUCTION CAPABILITY

Depending on your purpose and your budget, the more the quality and quantity of ozone produced the better for you. There is a directly proportional relationship between the amount of ozone produced. Hence the amount of fresh oxygen your lungs feels exposed to.

iii. ODOR ELIMINATION, MOLD CONTROL, AND REMOVAL

Most ozone generators are capable of odor elimination. But be sure before you buy that ozone generator to check further. This feature shouldn’t only come alone without mold control and removal. What is the usefulness of an ozone generator if it is incapable of doing all this in one fell swoop.

iv. MAINTENANCE

I am a sucker for low maintenance equipment. I strongly believe in the maxim that time should be spent on other important things as much as possible. So, instead of spending time maintaining equipment now and then, why not buy one that requires low human intervention when in use or after use?

v. THE RELATIONSHIP BETWEEN PORTABILITY AND SIZE

For industrial-based ozone generators, portability is critical. Even for indoor and everyday household usage, simplicity is key. While an ozone generator is important, it shouldn’t come at the expense of too much space in the living room. Hence it shouldn’t prove too difficult to transport.

vi. WARRANTY

The more, the merrier. Also, look out for alternative deals in situations where you love a product. But the warranty isn’t so much, do they provide cheap or free servicing or replacement of faulty parts? Or do they ship extra spare parts with your order, most especially ozone plates? These usually stop generating ozone with continued usage. Hence needs replacement from time to time. Usually, make sure your ozone plate has an hour rating of at least 5000 hours. This means it can produce ozone for 5000 hours before a noticeable drop in its ozone-generating capacity.

THE BEST OZONE GENERATORS

1. ENERZEN COMMERCIAL OZONE GENERATOR 3500MG INDUSTRIAL O3 AIR PURIFIER DEODORIZER STERILIZER (BLACK) – BEST BUY

The Enerzen commercial ozone generator is a 6.8 x 8 x 5.8 inches ozone generator. Weighing 5 pounds and shipping at 5.7 lbs, this ozone generator is one of the best ozone generators in the market. Although it advertises that it produces an average of 3500mg of ozone and a maximum production capacity of 4000mg. This unit has been shown to generate over 4100 to 4200mg of ozone which is amazing. This is a function of its super cool ozone plate.

Coming new and improved, this portable and lightweight design unit comes with a larger fan. It sterilizes more square feet for the same price we’re used to paying. Thus, ensuring better ozone distribution. It is also low to maintain since it works absent from an air filter. Its portable, light, and compact nature. This means you can use it from your office, home, car, boat, and almost anywhere!

The Enerzen commercial ozone generator is also a powerful odor eliminator, mold controller, and removal. It’s capable of eliminating any malodors. From cigarette/cigar smoke, pets, mold, dust, smoke damage, water damage, paint/cleaning fumes, cooking odors, and many more. It doesn’t only get rid of them, but it retards fungus, mildew, and mold growth as well.

Many firefighters use the Enerzen OG. And finally, its eco-friendly design is one we have come to love. It makes this unit consume significantly lower energy than other units.

PROS	CONS
They have a 30 days return policy where your ozone generator is either replaced with a brand new one. Or you get a cash refund if you are not satisfied with their products.	As for the quantity of ozone generation, its output capacity of 4000mg isn’t the best as touted. For instance, ozone power op5000 generates 5000mg. Hence it is also a commercial ozone generator much like the Enerzen.
The size of the Enerzen ozone generator’s blades helps it produce more ozone per square meters. As compared to most other industrial-grade ozone generators.	The eco-friendly mode is only available in the USA 100v only model.
The industrial steel casing makes this baby sturdy. Hence more durable than your average run of the mill ozone generators.
Also, its eco-friendly design is one we have come to love. It shows a responsible commitment on the part of the designers towards a better planet.

2. OZONE POWER OP5000 COMMERCIAL AIR OZONE GENERATOR 5000MG & AIR PURIFIER | NATURAL ODOR REMOVER | 5 YEAR WARRANTY

It’s larger than the Enerzen ozone generator and standing at a dimension of 9 x 9 x 7 inches. The OP5000 is one of those ozone generators that rely on the Coronal discharge method for ozone generation. This creates ozone (see above under ‘Mode of Generation’ for what the Corona discharge method is). A more simplified way to describe this method of ozone generation is to draw a parallel that in nature. The Corona discharge method is the way ozone gets generated during thunderstorms by lightning strikes. Hence that cold fresh smell of the air after the rains as the Corona discharge method is nature’s secret weapon for fighting odors and purifying the air.

It weighs 5 pounds and ships at 6 lbs. Due to the higher proportion of ozone capable of being generated (5000mg), this unit boasts of being designed to handle any odor. Hence it’s capable of a 100% success rate in ridding your room or storage space of unwanted odors.

You can use it in most places, as long as you have 110V power.

Now one thing we didn’t like a lot is the advertised 5 YEAR EASY EXCHANGE WARRANTY. The shipping costs are prepaid, which means you pay for it. Also, most times you need to send your old unit to them at a price which is much more expensive than the cost of a brand new unit of the OP5000. We found this to be very dubious.

PROS	CONS
Higher ozone output generation of 5000 mg.	Bad customer care services provided by the manufacturers when you call in demanding real help.
Ozone generators of a much larger size have been known to produce less ozone than that generated by this unit. This is a testament to the design abilities of the manufacturers.	While their five-year warranty may appear excellent, bad customer care almost ensures that it’s hard to cash in on. Most of the time they would insist you send the defective product to Canada for a fee paid by you. It’s for a price which is much more expensive than the cost price of a unit of the OP 5000.
Despite its larger dimensions, it still weighs the same weight of the Enerzen ozone generator. This means it’s portable for its size.
It runs on the Corona discharge method.

3. A2Z OZONE AQUA 6 MULTI-PURPOSE OZONE GENERATOR – BEST HOME APPLIANCE

The A2Z Ozone Aqua 6 is another ozone generator that works using the Coronal discharge method. It comes beautifully designed and sleek in white. It’s made exclusively for home, and small scale supply of ozone. The manufacturers put a lot of thought into this particular usage of the generator. Hence it is lightweight. Most of the things we loved about it arose from this particular function as was what we didn’t like.

It comes with at 11 x 3 x 8 inches and shipped at a weight of 3.1 pounds. The A2Z Ozone aqua six multi-purpose ozone generator is easy to install. It contains two 36′ polyurethane tubes and two 1′ diffuser bubblers. So that it is essentially a plug and play type ozone generator.

This ozone generator is capable of certain specific uses. Where these conventional commercial ozone generators are incapable of. This is achieved by its specialized timer equipped with 15 settings for different applications. Some of which include:

1. Freshen up a small space

The above is the primary function of an ozone generator anyway. The controller has nine different repeat functions for as many times as you wish.

2. Increases the shelf life of fruits and veggies!

You can also use this unit for rinsing and washing fresh fruits. Fill your sink or bowl with water, drop the diffuser 2-4 minutes into the water. Then, leave it to ozonate the water for some 10-15 minutes. Only place the fruits and vegetables into the water before or after ozonating the water. Never during ozonating.

3. Ozonate your flowers!

Ozonating freshly cut flowers help them last longer. Some users of this unit even note new leaf growth on the stem of flowers that were ozonated.

4. Treating tap water

The unit can purify from a glass of water to a gallon by using the Function setting #1 (2 minutes run time).

PROS	CONS
The A2Z Ozone aqua six multi-purpose ozone generator is so beautiful and sleek in design.	Despite not being an industrial ozone generator, we were still not quite pleased with the shelf life of this device. It stops manufacturing ozone most times usually after several months of continuous usage.
The color, it comes in white. Unlike its industrial-grade counterparts that are a mainstream black or pale gray.	The above is because of the plates inside the Ozone aqua six multi-purpose ozone generator. The manufactured ozone needs recharging every now and then for it to be of continuous use. This requires someone with the technical know-how to handle it. Thus, it is, at least for now, impossible to send it back to the manufacturers for recharge.
It can be wall-mounted.	It is not very durable.
t is very portable and very easy to install, whether on the wall, floor, kitchen countertop, or table.
It’s perfect for home or office use.

4. FRESH AIR COMMERCIAL AIR PURIFIER OZONE GENERATOR 3500MG CLEANER DEODORIZER SILVER COLOR (SILVER)

Fresh Air commercial air purifier ozone generator might appear moderately sized. But do not let its size fool you. It comes from a dimension of 7 x 6 x 6.5 inches and weighing 5 pounds. This ozone generator manufactured by Breathe Fresh Air comes highly recommended as an ozone generator. This is because of its durability and its high concentration of ozone production..

This ozone generator deodorizes and eliminates almost most every bad odor you can think of. Ranging from cigarette/cigar smoke, dust, pet odors, and many others. It’s capable of producing ozone at an average rate of 3500mg. Also, it destroys Airborne Bacteria/Viruses/Germs. Hence removes allergens such as pollen grains from the air. This unit isn’t only capable of masking odors; it can as well remove them from your air!

The unit also comes with a timer that you can set, and then leave to return later after it has worked its magic. But, I must warn you, for total deodorization, return 1 to 2 hours later after putting off the machine. While the unit is still turned ON and working, the air would smell like chlorine/bleach in high concentrations. But, this is only the air being scrubbed of bad odors, it is very normal. What you smell is the raw ozone in high concentrations. If you return in an hour or two’s time with the ozone concentration now lower, it smells like after a lighting storm.

It is also low to maintain as it doesn’t contain any air filters that need cleaning. The unit is ‘plug and play’. So it needs no special assembly, it’s ready to operate or run upon arrival. Its warranty is nothing to be exactly ecstatic about though as it comes with only a one-year warranty.

PROS	CONS
The unit is capable of producing a huge supply of ozone. Hence you might think it is more of an odor remover than an air purifier, but that is not so, it does both.	The pungent chlorine-like smell from this ozone generator takes longer than it takes to dissipate. Compared to other ozone generators. Although this is a testament to its capacity to provide raw, unadulterated ozone. But, we still found this to be a turn off; hence, it is not advisable to use the unit for occupied spaces.
Low maintenance.	Cheap warranty, only one year.
Portable and average weight.

5. SYLVAN OZONE GENERATOR 4000MG/HR AIR PURIFIER

The Sylvan ozone generator is a large 12 x 9.8 x 9.5 inches ozone generator clocking 7.5 pounds. Before we go into all the details about this unit, one thing that thrilled us is the presence of a spare ozone plate.

Ozone plates usually on average work for about a cumulative period of 6000hrs. So, with its added extra plate, this unit is capable of generating ozone for an extended period of 12000hrs. Hence before you ever need to replace the ozone plate.

It produces 4000mg of ozone per hour when set at maximum. The Sylvan ozone generator comes equipped with a 0 – 120min timer. Moreover, it holds a function that you can adjust to temporary shock treatments or continuous air purification mode.

This brand of ozone generators is also used by professional fire and water damage restoration specialists around the world. So it would mean it comes very highly recommended.

It comes cased in a black powder coat aluminum case and has a maximum treatment area of 160,000 cubic feet.

PROS	CONS
You know we are a stickler for freebies. So it’s obvious we’re thrilled on the extra bit of Ozone plate delivered to us. This enables a longer period of ozone generation gotten from the unit.	For the amount of ozone it produces, the large size was unnecessary. Compared to the Enerzen model that produces the same output but is 2.5 pounds lighter, we didn’t see the need for this.
Large maximum treatment area.
Professional endorsement by firefighters is a testament to the device’s ability.

6. FRESH AIR COMMERCIAL AIR PURIFIER OZONE GENERATOR UV STERILIZER 4,000MG/ HR 4G CLEANER DEODORIZER UVC

The Fresh Air commercial air purifier ozone generator UV sterilizer 4000mg, as the name suggests is an ozone generator that generates ozone using the ultraviolet light method of ozone generation. It comes with a dimension of 11 x 7.5 x 9 inches and weighing 12 pounds. This means that it relies on a light source to produce a narrow band UV light. It converts oxygen in contact with ozone.

It is also manufactured by Breathe Fresh Air and is quite durable. One amazing thing that thrilled us is their 30-day return policy, the same as those of the Enerzen. They accept a return of the product, no questions asked, and replace it. It is unclear if they alternatively in a situation where the customer doesn’t want a replacement. Hence refund the cash used in purchasing the item.

Another thrilling thing about this product is the spare parts that come with it. The Sylvan ozone generator comes with an extra ozone plate. This unit comes with a whopping 3 ozone plates, i.e., 2 extras. Each has a 5000-hour rating, hence removable for easy replacement. What the 5000-hour rating means is that you can use each plate for a maximum time of 5000 hours. This is before the consumer begins to notice a drop in ozone generated by the unit.

The unit comes with a timer you can set and come back after using it to work its magic. But, we must point out here that the unit does not have a hold setting though the physical product says ‘Hold’ on it.

PROS	CONS
The unit is capable of producing a huge supply of ozone.	It is quite big in size.
It comes with a whopping three extra ozone plates, each with a 5000-hour rating. Weak warranty, only one year.	Weak warranty, only one year.
The product has a 30-day return policy. So, make sure you try out your shipment for the first 30 days after it arrives to cure your doubts or make up your mind.

7. FOREVEROZONE 20,000 MG/H SHOCK TREATMENT OZONE GENERATOR – BEST OUTPUT

The Foreverozone shock treatment ozone generator is a MONSTER!!! Considering that all the ozone generators we had used and reviewed up until now had a maximum ozone production output of 5000mg/h. I am in awe of this beast.

You would expect this monster to be humongous in size. But it isn’t, it comes at a little 8 x 5 x 5 inches in dimensions and weighs only 5 pounds. So how then does it generate so much ozone you might wonder? It does this by utilizing two solid-state transformers mounted on 1/4″ Plexiglas. It’s provided with a sideways heat sink, fitted to these transformers. This unit aids better cooling of the system while it is working tirelessly.

It also comes inclusive of a three-outlet adapter and doesn’t need the use of batteries. Also, it comes fully assembled without the plates which are easy to affix by self.

This unit has removable ozone plates and a grounded power cord and can be used for any of the following tasks:

1. For the permanent removal of heavy smoke smells.
2. For the sanitation of air and the elimination of toxic biohazards. Such as viruses, bacteria, molds, pet feces, chemicals, and other indoor air allergens.
3. For the destruction of mites and parasites. Including small insects whether flying or not.
4. The Foreverozone treatment ozone generator can also be used for the removal of airborne and surface molds.

PROS	CONS
This unit is an absolute monster. That should say enough right, but if it doesn’t, consider the fact that it weighs only 5 lbs. The ozone generator is capable of producing 20,000 mg/h of ozone and be in awe. Go ahead!	They are not very durable.
Its replaceable ozone plates are so easy to remove and replace.	The reasonable pricing comes at the expense of a fancy case and fan. So it requires extra care and cooling to ensure the unit doesn’t overheat.
It has a grounded power cord.
The pricing is also very reasonable.

8. COMMERCIAL OZONE GENERATOR 3500MG INDUSTRIAL O3 AIR PURIFIER BLACK DEODORIZER STERILIZER

This unit provides proper ozone of the usual average generation quantity of 3500 mg. This is for anyone who seeks to get rid of smell and odors, smoke and mold in enclosed spaces of up to 4000 square feet. It also makes use of standard ceramic ozone plates which can last for 5000 hours of ozone generation. As always, you need to change the plates when there is a noticeable drop in ozone production capabilities. It also boasts of being very easy to use.

How to use the unit:

First, you insert the accompanying plug of the unit into any 110v outlet. With the aid of the built-in timer, set the ozone generator to the desired treatment time. Cars usually need about 30 – 40 min and medium-large rooms for 40 min to one hour. Hence basements need an hour to two hours and an entire house for about 2 hours.

Note that while space or room is being treated, you need to leave it unoccupied. The concentration of ozone is sure to make the air irritating to breathe during treatment. After the treatment time is over, wait for about 45 min to an hour. This is for the ozone inside the space or room to dissipate and breakdown into oxygen.

The number of treatment cycle space required depends on how severe the odor of the space is. It is usually more efficient to run the unit in bursts/cycles than non-stop for extended periods of time. That’s more than 4 hours at a time.

Also worthy of note is that the Commercial ozone generator 3500mg has an exclusive ‘always-on’ hold feature. This allows it to run for more than 2 hours at a time, or to be paired with a wall outlet timer for automated use.

Like other types of ozone generators, it works mostly on all odors and you can use it in most places. It also comes with a decent five-year warranty. We can all agree it is better than that provided with the Fresh Air commercial air purifier ozone generator (1 year). This is some breath of fresh air.

PROS	CONS
It is very easy to use.	The features are quite very average. Nothing makes this unit stand out in particular from the park. Even its weight is the average of five pounds.
It has a five-year warranty.	Lack of an eco-friendly design.
Its size is also portable.	Didn’t have the decency to include an extra ozone plate.
Because it is a very average item, a lot of its parts that need replacing can be easily replaced. For instance the ceramic ozone plate.

9. DELLA 048-GM-48245 UV OZONE GENERATOR AIR PURIFIER FRESH CLEANER HEPA COVERS 3500′, CLEAR ACRYLIC

Standing like a tower and with dimensions, 11 x 12 x 15 inches, is the Della UV ozone generator weighs 15.4 pounds. It is quite too large for the capacity of ozone it purportedly produces, only 3500 mg/h. Although the manufacturers claim that it produces up to 30 Percent more ozone than other brands, we did not see this. The Enerzen in use produces more than 4000 mg/h, the Ozone power OP5000 produces over 5000mg/h.

One unique feature to be proud of though is the Air Purifier mode. When in use, it enables this unit to function as a regular Air Purifier. Thus, purifying air for 24 hours, seven days a week, nonstop.

Another thing we loved about this unit is the presence of washable filters. They help in odor removal, mold elimination, and bacteria destruction. You can take these filters off and wash them. Do this when they become over-clogged with dust and then reuse as almost brand new.

At this point, we must say we loved the tower design of this ozone generator. It doesn’t make it seem like your average run of the mill ozone generator. It’s a high-end appliance that will look good in any home and it’s designed to last for many years.

Robust – 2 plate ozone system, powerful UV Bulb, a powerful fan for up to cleaning 3500 sq. ft.

PROS	CONS
One thing that thrilled us when using the Della UV ozone generator was that it has a variable functionality mode. It allows you to use it as a natural air purifier. It’s capable of running for 24 hours nonstop seven days a week, to keep the air clean and fresh.	For its humongous size and weight, its ozone generation capability is quite average at 3500 mg/h.
We were quite taken with the tower-like design of this unit.
Its washable filters were also quite endearing. This means that when the filters get clogged, you can take them off, clean, and reuse.

10. SYLVAN  VARIABLE OZONE GENERATOR 5000MG/HR ADJUSTABLE OZONE OUTPUT – HONORABLE MENTION

The above unit is Sylvan’s reply to the OP5000. It stands at an impressive 13.1 x 10 x 9.4 inches and weighs only 8 pounds. The Sylvan variable ozone generator is capable of generating 5000mg/hr of ozone.

But that’s not all. The thing that endeared us to this unit is the presence of a variable ozone control. What this dial ensures is that a consumer can set the ozone output of this unit from a range of 0 – 5000mg/hr. Wait for a second, that’s not all. As a result of this, you have an ozone generator that you can use as an air purifier in occupied spaces. Even in small rooms without the noticeable strong chlorine-like smell of concentrated ozone. Hence in the presence of pets and humans.

The timer has a range of 0 to 2 hours and a ‘Hold’ function. You can set the ozone generator for temporary shock treatments. Or continuous air purification mode. Sylvan Brand Generators have been known to be used by professional fire and water damage restoration specialists. So it is safe to say you can trust their judgments on this.

PROS	CONS
The capacity of ozone been generated by this product, was one of the best things about it. When compared to the size, it is not a bad bargain.	Insects have been known to get trapped in its intake port, and this is due to the absence of a filter. So what this unit needs is a filter for the intake port to prevent debris. Hence insects from entering in and out the ozone plate.
Excellent customer care by the Sylvan team as they’re known to replace faulty parts with little or no cost to the consumer.
Its adjustable dial which enables its function even in the presence of pets and humans.

Conclusion

As humans, we owe it to ourselves to live as healthily as we can afford to and the ozone generator ensures that. It ensures that we breathe a better quality of air, free of noxious fumes and many others.

Don’t forget that making a decision on the type of ozone generator you want is a no-brainer. Only if you follow our directions above. Don’t forget that many companies offering a good warranty might have roundabout ways to claim them. It is wise to avoid these people.

But, to aid you in making your decisions, we have listed some items with special tag lines. ‘BEST BUY’ the ozone generator that will give you good quality for your money. ‘BEST HOME APPLIANCE’ the ozone generator that you can use in all places in the house for varying many applications. ‘BEST OUTPUT’ the ozone generator that delivers the highest amount of ozone out of all the products reviewed. And finally, we have the ‘HONORABLE MENTION’ tag for the ozone generator. It’s also guaranteed to give you good value for your money but doesn’t fall into any of the above categories.
