Edenpure Oxileaf II Thunderstorm Review 2024

EdenPURE OxiLeaf II Thunderstorm review

The EdenPure OxiLeaf II stands out in the air purifier market for its compact size and innovative approach to air purification.

Remarkably small, this purifier is designed to be handheld, barely exceeding the dimensions of a standard outlet cover it’s meant to plug into. This starkly contrasts with the bulky designs typical of traditional air purifiers.

What sets the OxiLeaf apart is its method of purifying air. Unlike conventional purifiers that rely on pulling air through filters to cleanse it, the OxiLeaf transforms the surrounding air into ozone, which then circulates throughout the room, neutralizing odors and eliminating pollutants on the go.

This innovative mechanism allows the EdenPure OxiLeaf to operate without the need for filters or any replaceable components. Despite its diminutive stature, it claims to offer exceptional performance in reducing odors, pollutants, pathogens, and allergens, even in spacious areas.

Edenpure Oxileaf II Thunderstorm review

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 use in an RV.

The EdenPure OxiLeaf II Thunderstorm Air Purifier offers straightforward operation.

Designed for convenience, this compact device easily plugs into a wall socket or can be powered through a USB port, making it ideal for travel or use in an RV.

It features a simple dial on its side for adjusting the ozone output from a minimum of 0.4 ppm to a maximum of 0.8 ppm. Lacking an on/off switch, the unit requires unplugging to be turned off.

With no need to replace filters or batteries, operating this mini purifier is effortlessly simple.

Edenpure Oxileaf II Thunderstorm – Features

The EdenPure OxiLeaf II Thunderstorm is an air purifier that uses ozone generation to combat odors and pollutants in the home. While its odor-eliminating capabilities are notable, the health implications of ozone exposure raise concerns about its overall safety and effectiveness. Here’s a closer look at the advantages and potential downsides of this device.

Odor Elimination Capabilities

The primary strength of the EdenPure OxiLeaf II lies in its ability to neutralize odors. Ozone, a molecule made up of three oxygen atoms, is highly reactive and effectively interacts with volatile organic compounds (VOCs), which are the main culprits behind household odors. This makes the OxiLeaf particularly efficient at breaking down and eliminating a wide range of smells.

Many users report significant improvements in indoor air quality and odor reduction. However, individuals with heightened sensitivity to ozone may find the smell of ozone itself to be unpleasant, potentially outweighing the benefits of odor elimination.

Air Purification Performance

The OxiLeaf claims to remove 99.9% of airborne contaminants, but this assertion is met with skepticism. The interaction between ozone and pollutants doesn’t always result in harmless byproducts; sometimes, it can produce more harmful substances than the original pollutants. Moreover, the effectiveness of ozone in eliminating pathogens and large particles is questionable without reaching unsafe ozone concentration levels for human exposure. This limitation has led to dissatisfaction among some users, particularly those seeking relief from allergies or respiratory issues.

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.

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.

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 a USB port.

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.


The compact purifier operates with a subtle hum, reaching a maximum noise level of approximately 34 dB, which is quieter than a whisper. Nonetheless, considering our advice against using this unit in spaces with people present, the device’s low noise feature, often highlighted by the manufacturer, becomes somewhat irrelevant.

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.

  • Effective Air Purification: Efficiently eliminates a wide range of contaminants.
  • Cost-Efficiency: No need for filter replacements, leading to lower maintenance costs.
  • Portability: Compact and lightweight, ideal for travel and versatile use.
  • Health Risks from Ozone: Potential respiratory irritations and problems, especially for those with pre-existing conditions.
  • Initial Strong Odor: May emit a distinct, metallic smell upon activation.
  • Noise Level: Could be louder than expected, potentially disturbing light sleepers.

Safety Concerns

The use of ozone as a purifying agent is controversial due to its potential health risks. The Environmental Protection Agency (EPA) labels ozone as a harmful substance that can damage the lungs and exacerbate respiratory conditions. The OxiLeaf operates at ozone levels (0.4 to 0.8 ppm) that far exceed the outdoor air quality standards recommended by the EPA and the workplace safety guidelines set by the National Institute of Occupational Safety and Health.

Given these safety considerations, it’s advised not to use the OxiLeaf in spaces occupied by people. Rooms treated with the device should be well-ventilated before re-entry to ensure safety.

In summary, while the EdenPure OxiLeaf II Thunderstorm offers effective odor control, its air purifying claims and safety concerns due to ozone generation warrant careful consideration. Potential users should weigh the benefits against the risks, especially in environments with vulnerable individuals.

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).


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.
