Edenpure Oxileaf II Thunderstorm – Features

Edenpure Oxilieaf II Thunderstorm has some unique features, as it is not your typical air purifier with a filter. These are:

Safe Ozone Technology. This device belongs to an exceptional group of air purifiers. It is classified as an Ozonator/ozone generator, which uses Ozone to purify the air. So instead of pulling the air inside and cleaning it via a filtration system, an Ozonator releases ozone molecules into the air. These molecules then attach themselves to contaminants/air pollutants and destroy their cell walls. Ozone molecules destroy air pollutants while reverting Ozone back to oxygen. An Ozonator is effective against bacteria, fungus, germs, odors, and other air pollutants. The Oxileaf II unit is also twice as fast as the original Oxileaf I (discontinued). So for people asking if edenpure thunderstorm is safe, yes, it is entirely secure.

Dual vent technology. Two vents (one on each side) ensure an even distribution of the purification process. Doing this eliminates any worries or requirements on how you would otherwise have to turn the device to achieve optimal purification results.

Simple and clean interface. Â You only get a built-in indicator light for effectiveness and an adjustable knob for Ozone. You can adjust the ozone output from 0.4 – 0.8 ppm. I will touch more on this subject later.

I added USB port. Â In addition to a normal plug, this unit also comes with an 8′ USB Cord. This increases flexibility and ease of use.

Effective for medium-sized rooms. I did not find any information about an actual room coverage number but based on edenpure thunderstorm reviews and similar devices; I estimate the maximum (of one unit) to be around 200 square feet.


This mini purifier makes a low noise while it is being used. The maximum noise output is only about 34 dB, quieter than a whisper.

Although the company boasts about the low noise level of this unit, we do not recommend that it be used in occupied spaces.

Easy to use

The OxiLeaf is easy to use. You just plug it into the wall, and it hangs off the outlet. You can also attach it to a USB port for traveling or using in an RV.

There is a dial on the side of the unit that you can use to control how much carbon dioxide is released. The range is from 0.4 ppm (parts per million) to 0.8 ppm. There is no on/off switch, so you must unplug it to turn it off.

This mini purifier is easy to operate because you don’t need to worry about filters or batteries.

Safety concern

The EPA says that Ozone is a toxic compound that can harm people’s health. Ozone is a powerful air cleaner, but it can also cause damage to the respiratory system, especially for people with allergies or asthma.

There is a lot of controversy around using ozone generators like the OxiLeaf. Some people believe it is healthy to have ozone levels in your home below 0.08 ppm, while others think that levels of 0.10 ppm or above are unsafe.

The EdenPure OxiLeaf has a default ozone output between 0.4 and 0.8 ppm. This represents that the air near the unit will be more than twice as clean as the recommended ozone exposure level selected by these regulators.

We recommend not using the OxiLeaf in occupied rooms. Rooms that have been purified should be adequately ventilated before anyone spends time in them.

Edenpure Oxileaf II Thunderstorm – Pros & Cons

In this section, I am going to break down some of the positives as well as the negatives of Oxileaf II. As I do in my other reviews, I will elaborate on these pros & cons individually. By doing this, I aim to better understand you and ultimately help you decide if this device is a good fit for you.


Excellent air cleaning capabilities. Ozone molecules are one of the most effective ways of air purifying. One of the primary uses of ozone generators is for the following contaminants:

Mold and mildew mold are especially harmful to our respiratory system. Asthma and allergy sufferers also benefit significantly from mold and mildew removal, as they are one of the leading causes of asthma attacks and allergies.
-Odor. I have a lot to write about ozone generators and odor, for which I will dedicate an entire section after pros & cons. All you need to know, for now, is that many people use Ozone specifically for odor issues.
Bacteria, germs, and viruses. This is a big one since these organisms are often smaller than 0.3 microns. I mentioned 0.3 microns because that is the smallest harmful particle size that HEPA filters can effectively remove. On the other hand, Ozone is not limited by the size of these microorganisms, as it destroys them on a molecular level. In this way, it is more effective than HEPA filters.

In addition to this list, Ozone completely removes the most common house contaminants: Â dust, pollen, smoke, pet dander, carbon monoxide, and dust mites…basically pretty much all organic and inorganic pollutants. 

Cost-effective. Another big plus about this device is that you have no additional costs associated with it. Edenpure Oxileaf II Thunderstorm does not use filters or fillers, saving you quite a bit of money over time. Also, no parts need to be replaced, so you have an almost non-existent maintenance cost.

Portable. With dimensions of 5.125†H x 4.3†L x 2†D and a weight of less than a pound, Oxileaf II can be taken with you anywhere. It’s very compact size makes it an ideal traveling companion.


Ozone is a health hazard. Â One of the main negatives of ozone generators in general…is Ozone itself. We consider it dangerous because it is a very reactive chemical that stays reactive even when we inhale it. Ozone can cause irritations and other respiratory problems in our lungs, even in smaller quantities. It affects anyone with respiratory problems (namely asthmatics and people with allergies) even more. Ironically, working out people are especially exposed if they are near an ozone generator during a workout. This is because as you work out, your air intake increases, together with inhaled Ozone. Edenpure Oxileaf II Thunderstorm emits 0.8 ppm of Ozone on max settings, which is more than the recommended limit by the FDA.

Possible strong initial smell. Â Ozone comes with a very distinct, somewhat strong odor. When you activate this device, you can experience a specific odor coming from the device, which gradually moves across the room over 2-3 hours. It is similar to a metallic smell which, as mentioned above, loses intensity over time.

It can be a bit noisy. Â Some users report the device emitting a bit more noise than expected. The manufacturer lists 26-34 dB SPL (sound pressure level). Generally, sleep can get disturbed by a noise above 45 dB. 34 dB could be a minor issue for light sleepers – but in that case, you can always use the control know to lower the output setting. By doing that, the noise should go down.

How effective is Oxileaf II against common odors?

I wanted to touch on this topic in a separate section of my edenpure oxileaf ii thunderstorm reviews because the question is very broad, and the answer is very specific. All odor molecules are classified as volatile organic compounds (VOC). Despite that, Ozone interacts a bit differently with each of them.

  • Pet odors: the most common reason for the specific scent that our beloved pets emit is pet dander, which is challenging to remove by traditional methods. In general, an ozone generator successfully masks any pet odors due to dander. The other source of solid pet odor is urine. Since urine does not oxidize, you must first deal with the source of this smell (carpet stain, etc.) and then turn on the ozone generator.
  • Cigarette smoke: smoke, in general, is one of the most harmful air pollutants and consequently one of the hardest to remove. Ozone generators are very effective in removing (cigarette) smoke and are often used when everything else fails.
  • Large car odors: since Oxileaf II is so small and portable; I decided to include it here as well. This section is especially relevant for trucking companies or for anyone who deals with a lot of transportation, where the smell (depending on cargo) sometimes requires frequent odor removal. In this case, you would have to keep the ozone generator running for a couple of hours, which is typically enough to give you good results.
  • Human smells/body odor: ozone generators are also compelling at masking and removing any body odor. People usually try airing out the room, which is primarily ineffective, whereas an ozone generator provides a good solution. Many experts recommend trying a traditional air purifier with filters first before jumping straight to an ozone generator (due to the negative side of Ozone).

Edenpure Oxileaf II Thunderstorm review- conclusion

All in all, Edenpure Oxileaf II Thunderstorm is a great air cleaning device. It cleans the air more effectively than the highest-graded HEPA filters, you can almost fit it in your pocket, and the affordable pricing almost makes it a steal. I recommend it to anyone looking for premium cleaning capabilities above all else. It is effective against most smells, the smallest bacteria, and viruses. This gives it an advantage over traditional HEPA filters. Also, I love that this device has no additional costs – no filters or other parts that you would need to replace. The size, weight, and USB connector make it a great portable travel companion.

Despite that, my recommendation comes based on a few conditions. Firstly, the high ozone output means you do not want to keep this device on all the time. When it is on the highest settings, I would recommend not being very near the device (to limit your exposure to Ozone). If you are a heavy asthmatic or have severe allergies…then I would look at an ozone-free ionizer instead of an ozone generator. Anyone with respiratory issues is much more sensitive to even smaller amounts of Ozone. Also, if you work out at home, ensure the Edenpure Oxilieaf II Thunderstorm is turned off during that time.

Overall a very great performing air purifier with a very affordable price tag, suitable for most air cleaning needs.
