IQAir HealthPro Plus vs Oransi Ej120 | Air Purifier Comparison

IQAir HealthPro Plus vs Oransi Ej120

Today we will be looking at and comparing two top-tier air purifiers that you can currently get on the market – IQAir HealthPro Plus versus Oransi EJ120. Choosing the correct air purifier is an important thing, even more so when there is a hefty price tag attached. Most expensive air purifiers are long-term investments, so it makes sense to pick the one that is more suited to your needs. For this reason, I have made this product comparison post, where I will be doing an in-depth analysis. My end goal is to help you decide whether IQAir HealthPro Plus or Oransi EJ120 is a better fit for you. Let’s dive right in.

IQAir HealthPro Plus vs Oransi Ej120: Product specifications

First, we will take a look at the product specifications for both of these top-tier air purifiers. I have prepared all of the important information in a side-by-side comparison table below.

In terms of weight and product dimensions, IQAir HealthPro Plus is a bit taller and bulkier than Oransi EJ120. Despite the large size, the proportions still make it a very flexible design that can be utilized in any room. While HealthPro Plus is heavy, it can be moved with an optional set of 4 wheels, which come included in the package. The design is also very distinct and you can immediately tell that it belongs to the IQAir family. On the hand, we have the Oransi EJ120, which is smaller, lighter, and more compact than HealthPro plus. This does give it a slight edge in terms of portability, which is always a nice thing. The design of model EJ120 is… interesting to say the least, as it is not similar to any other design trends of top-tier air purifiers.

Next, we got certifications. Oransi EJ120 is quite a bit more efficient than IQAir HealthPro plus, which means that you save some money on electricity long-term. For this type of performance, it is no wonder that it got the Energy Star certification. It also comes with all other certifications that you would expect from mid and top-tier air purifiers: UL listed, CARB, and AHAM. These basically mean that the EJ120 model does indeed do everything it claims to do.

HealthPro Plus does not have your standard “official” certification. Instead, they chose to approach this from a very unique angle through a “Certificate of performance”. What does this mean? Before shipping any air purifier, IQAir will test each one of these units individually in order to guarantee they meet the performance standard. You get these measurements (tied to your air purifier) written on paper, together with your air purifier. How unique is that! While all measurements are made via internal testing, you can still be sure that what you get is the real deal.

Another very surprising thing that both HealthPro Plus and Oransi EJ120 have in common is a 10-year guarantee. Most air purifiers come with a 1 or 2-year guarantee, so 10 years is a huge upgrade. This speaks volumes about how much both of these well-established brands believe in the quality of their product. Nothing more needs to be said here.

IQAir HealthPro Plus vs Oransi Ej120: Features and effectiveness

This is going to be the main portion of my comparison, where I will take a look an in-depth look into both main product features. Similarly to the paragraph above, I will first display all of the necessary information in a side-by-side comparison chart, and then give you an analysis of the differences and similarities. I will pick a winner in each of these subcategories, based on my own experiences. Do note that this is only my opinion and should be taken as such.

Filtration system

Oransi Ej120 uses a pretty straightforward 2-stage filtration system that consists of a pre-filter and a true HEPA filter. The pre-filter is pretty unique and is not your typical average one, as it is also an activated carbon filter. This carbon filter is an “upgraded” version which is about 50% more effective than a regular one, making it really great for removing all types and smells, odors, and gases. Many individuals also rigorously tested this claim and they always came to the same conclusion – gas and odor removal is nearly 100%. As for the HEPA filter, it is just as you would expect from an expensive air purifier – effective. Oransi Ej120 uses a Merv-17 HEPA filter, which belongs in the top tier in regard to quality. This filter is made out of quality components, lasts for a year, and is very effective – you can be absolutely sure that it can remove 99,97% of harmful particles that are 0.3 microns or bigger.

IQAir HealthPro Plus has a different filtration system that consists of 4 stages. You get a pre-filter (called PreMax), activated carbon filter (granulated) + Pelletized chemisorption, and HyperHEPA filter. The pre-filter is washable, but not permanent (can be used for a year and a half, so keep that in mind!) and is very effective for removing mostly the largest harmful air particles. Next, I want to stop at the carbon-activated filter. This is a really unique aspect of IQAir as it is a combination of the granulated activated carbon filter and pelletized chemisorption. A lot of fancy words, but what does it actually mean? In short, it offers great protection against a wide array of chemicals and odors/smells. Lastly, I want to discuss the bread and butter of IQAir HealthPro Plus air cleaning technology – HyperHEPA. This is one of the most powerful HEPA filters currently on the market, as it is capable of removing even the smallest (ultrafine) particles, which escape the majority of other HEPA filters. HyperHEPA can remove particles as small as 0.003 microns – a big step up from 0.3 microns, which is the usual limitation. I would also like to point out that this filtration technology produces no ozone, making it completely safe for your health.

In terms of filtration system IQAir HealthPro Plus is the clear winner over Oransi Ej120 Out of the two, only HyperHEPA is capable of removing particles smaller than 0.3 microns (like many viruses are bacteria). The carbon filter is also a bit stronger and lasts longer, offering you complete protection from gases and odors. Zero ozone emission is also a big plus, which should not be overlooked. Do not get me wrong – Oransi Ej120 also comes with a fantastic filtration system but is slightly overshadowed compared to IQAir HelthPro Plus.

Room coverage

Oransi Ej120 lists their CADR rating at 333 Dust/ 331 Smoke/ 360 Pollen (cfm). This is quite a high number that basically tells you how fast an air purifier can clean a room, but it is NOT the definitive measure of how much (effective) room coverage it can provide. Oransi suggests using their Ej120 model for spaces of up to 1250 square feet. This is an enormous room coverage which would make this air purifier suitable for even extra-large spaces. The downside here is that you are getting only 2 ACH (air changes per hour) if you use it in such large spaces. 2 ACH is a below-average number which simply means that the air changes roughly once every 30 minutes. Anyone suffering from allergies or other respiratory issues should (ideally) aim for 5 ACH, while the average ACH of less powerful air purifiers usually moves in the 3-4 range. To conclude – the listed CADR rating is high (in general), but in this specific case it is a bit too low considering how much room it is supposed to cover. I need to add here that If you use Oransi Ej120 in smaller rooms, the ACH does go up to 4 – this is a big improvement, yet still falls a little bit short of the “sweet spot” of 5 ACH for allergy sufferers.

IQAir HealthPro Plus is in a pretty unique situation regarding room coverage, or more specifically CADR rating. Since the company does its own internal testing, there are no “official” numbers from AHAM which would tell us exactly how high these numbers are. Most individual testings estimated the CADR rating of IQAir HealthPro Plus to be over 300 cfm, with the possibility to go upwards to around 776 cfm. It all depends if it comes with the New Edition fan, which promises to deliver up to 41% more clean air than the “regular” version. The bottom line is that you are getting a superb fan that is capable of effectively dealing with spaces of up to 1150 square feet. This puts IQAir HealthPro plus as an amazingly large room air purifier choice that over-delivers in terms of room coverage and fan power. And the best party? It has an above-average ACH rating of 5, which means that it changes the air roughly once every 12 minutes. This is a fantastic number, making it a viable option for anyone that has respiratory issues such as allergies.

In terms of room coverage, I have to give the definite edge to IQAir HealthPro Plus over Oransi Ej120, despite the “official” smaller room coverage number recommendation. While Oransi Ej120 does technically cover a bit bigger areas, it still falls short due to the relatively low CADR rating for this kind of big room coverage numbers. The ACH rating is also considerably different, with IQair coming on top with 5 ACH vs Oransi’s 2-4 ACH. That being said, both air purifiers can be used in extra large rooms with confidence. Ej120 does a great job, but IQAir performs better due to superior fan power.

Noise levels

I want to preface this section with a short but straightforward chart for noise level range examples, so you get a better understanding of the numbers that are about to follow.

noise levels

Numbers in the middle represent decibels (dB). So for example, leaves rustling has a noise level of 20 dB, which is considered a faint sound.

Oransi Ej120 is sometimes jokingly referred to as the “Tesla of air purifiers” and there is a reason for noise – its noise levels. This is a very quiet air purifier, especially considering how powerful it is (here I mean its fan power and effectiveness). This is achieved thanks to an innovative EC motor, instead of a standard AC motor. On the lowest fan speed settings, you can expect the noise to be as low as 19 dB – this is an insanely low number, which is usually reserved only for the quietest air purifiers on the market. So how quiet is 19 dB you may ask? Well, it is the equivalent of mosquito sound or rustling leaves (20 dB), which is indeed really quiet. As for the fastest fan speed – it produces 59 dB of noise. This is a relatively high number but justified once we put it into the context of just how powerful this air purifier actually is. Is 59 dB suitable for the bedroom or study room? It is not optimal as any sound over 45 dB has the potential to disrupt our sleep, but honestly, it is not that bad. Also, there are multiple speeds that you can set, with the fastest one being the only “problematic” one in terms of noise.

IQAir HealthPro Plus has a noise level range from 22 dB (lowest fan speed) to 57 dB (highest fan speed) . Not much can be said here, considering it is very similar to Oransi Ej120. 22 dB can be considered very quiet and is the equivalent of a whisper. 57 dB is also a surprisingly low “maximum noise level” for a large room air purifier and be compared to the sound of a dishwasher or normal conversation, but slightly quieter. Is it suitable for the bedroom or a study room? Absolutely, you just have to make sure to put it on lower than maximum fan speed and you enjoy a full nights sleep.

In terms of noise levels, both IQAir HealthPro Plus vs Oransi Ej120 is identical, with no real noticeable differences. Both are considered very quiet large room air purifiers, suitable even for any rooms that require silence. Oransi is 1 or 2 decibels quieter on the lowest fan speed, and louder on the fastest speed setting, but this difference is so small that you would not be able to tell a difference.

Control panel

I usually have to write a lot in this section when it comes to other air purifiers, especially ones that have a high price tag attached. Oransi Ej120 is going to have to be my first exception in this area as the control panel consists of only a LED filter replacement indicator and a fan speed control. That is all you get – 5 adjustable fan speed settings and nothing else. This is a pretty common setup for Oransi in general, so it is not something that is associated only with the Ej120 model. The theme behind this is clearly “simplicity over complexity”, but I did expect at least an air quality sensor or something – after all, this is a very expensive air purifier. All I can do here is show an image of this control panel, which is located on top of the device.

On the other hand, we have IQAir HealthPro Plus which has a bit more to offer. It uses an electronic control panel that allows the user to cycle between 6 different fan speeds, set a system clock which can be then used for a timer function, and monitor the status of all filters. You can also lock the control panel, preventing accidental changes to your most recent settings. The filter monitor is pretty unique as it actually shows you how much longer (in hours) you can use current filters before they need to be replaced. There is a major lack of smart features, but you do get an automatic timer option. With it, you can program the device to automatically adjust fan speeds according to the time. What is also pretty neat is that you get a remote control, which can be used up to 20 feet away and is a nice convenience to have at times. Here is how the control panel looks:

The control panel of IQAir plus. Quite simple and straightforward, with some adjustable settings.

In terms of control panels and additional features, IQAir HealthPro Plus offers more adjustable settings and comes with more options than Oransi Ej120. While both of these lack true smart features such as an air quality monitor or automatic mode, you at least still get some automatization options with IQAir. Oransi Ej120 truly offers you just the “bare bones” in the form of a fan speed setting and that is it. A lot of other common settings such as a timer, sleep mode, light dimmer, etc… are simply not included. While this does not directly affect performance, it is still a nice convenience to have, especially at this price point. So the clear winner here is IQAir as it offers at least some additional features.

IQAir HealthPro Plus vs Oransi Ej120- Conclusion

We have two high-performing and brilliant air purifiers, from two respectable brands. Both can be used in very large rooms and use a similarly based HEPA filter technology, but with their own twists and improvements to deliver you the cleanest air possible. So which one is better, IQAir HealthPro plus or Oransi Ej120?

In my opinion, IQAir HealthPro Plus simply outperforms Oransi Ej120 in all of the important areas. It has a better filtration system that can capture even small ultrafine particles, is more customizable in terms of control panel settings, and has a stronger and more advanced fan while keeping identical low noise levels. It “officially” covers slightly fewer square feet than Oransi but performs better and quite faster. 5 ACH is also a fantastic number and the main reason why many large sites such as allergy recommend this model for anyone that suffers from allergies or other respiratory issues. The fastest fan speed can be a bit noisy, but this can be solved by lowering it during the night. The only real downside here is a lack of smart features (especially air quality sensors) and quite expensive replacement filters.

That being said, Oransi Ej120 is still a great air purifier. It is more portable than HealthPro plus, covers a bit larger areas, offers a fantastic filtration system that outperforms a lot of competitors, and is very cost-effective. Replacement filters are relatively cheap and the ridiculously low power consumption makes this a slightly better long-term financial investment than HealthPro Plus. So if you are looking for a bit more cost-effective air purifier, you can consider taking Oransi Eh120 over IQAir. The biggest downsides are the control panel (or lack of it) and a relatively low CADR rating for such a huge room coverage.

And there we have it. I hope this comparison helped you decide which one of these two air purifiers is a better fit for your needs. These are two very expensive air purifiers that will be a long-term investment, so be sure to choose the one that is best for your situation.
