Okaysou are pretty much the best bang-for-your-buck air purifiers.
This cannot be stressed enough:
The one thing that constantly came up in writing this Okaysou air purifier review is, “I can’t believe how great filtration system AirMax8L has. It’s only $120. You shouldn’t be able to get Medical Grade HEPA filters for that, much less the whole Ultra-Duo filtration system for 120 bucks.”
Mind you, the low price of Okaysou air purifiers might sound amazing for some. For us, it’s primarily disconcerting. Such a low price might indicate low performance, use of low-quality materials, or both.
Okaysou AirMax8L – the best Okaysou air purifier (based on 1000+ 5-star reviews) – has a CADR rating of 210, same H13 True HEPA filters (with Ultra-Duo system, no less), and 32-49 dB noise levels.
Alen BreatheSmart FIT50 is one of the best air purifiers in the world. Alen FIT50 also costs $550.
Okaysou AirMax8L is, performance-wise, almost identical to Alen FIT50. And AirMax8L costs $120.
Does Okaysou really produce $500+ air purifiers that are being sold for less than $200?
LearnMetrics has checked if Okaysou air purifiers are really too good to be true, or are they the real deal (and why they might be so cheap).
Critical Review Of Okaysou Air Purifiers
As we will see in the spec-by-spec comparison of 3 Okaysou air purifiers, their performance is equally pretty solid.
That leaves only one culprit for such a low price of AirMic4S, AirMax8L, and AirMax10L Pro Smart:
Lower quality materials of used (and hence unreliability).
If you look under the hood of AirMax8L, you can quickly see one thing: The use of hard plastic is not ideal. Definitely, Alen and Dyson air purifiers are made of better materials. That should be a reason for the 500% price tag, right?
Well, the truth to the matter is that Okaysou uses only decent-grade materials to reduce production costs. But the important question is this:
Does the use of non-expensive materials significantly reduce the Okaysou air purifier’s reliability?
Surprisingly enough, not at all. If you sieve through all those Okaysou reviews, you will hardly find people who complain about the lack of reliability in the Okaysou unit.
That’s quite positive feedback. In fact, to explain why Okaysou units are so cheap, we need to consider the dynamics of the air purifier market in the US. Here are the main characteristics:
- Incredibly competitive. Okaysou seems to be competing with low prices.
- Favors traditional brands such as Dyson and Alen. Okaysou has to reduce prices to become competitive additionally.
- Air purifiers have to have an art-gallery level of design to be appealing. Okaysou design is boxy; people will pay fewer dollars for a not-great design.
Together we see that the air purifier’s market forces reduce the price of Okaysou by so much.
In short, there is nothing wrong with the performance or even materials. For people looking for a budget-friendly price-performance choice of air purifier, you can’t get a better or cheaper air purifier than Okaysou.
Just look at the advanced 5-stage AirMax8L filtration system:
With that in mind, let’s look at a spec-by-spec comparison of all 3 Okaysou models. After the comparison table, you will find an explanation of all the specifications. Further on, it would be best if you also read individual reviews of:
All in all, it’s pretty evident that the AirMax8L – the flagship Okaysou model – is the best price-performance air purifier on the market:

Okaysou Air Purifier Reviews
Thus far, we have established the following about Okaysou air purifiers:
- They are made out of not perfect, but decent materials.
- Their specifications are similar to $500 air purifiers.
- They do cost less than $200.
Before checking individual reviews, let’s talk about the ins and outs based on which we can truly review Okaysou air purifiers:
Unique Filtration System
Air purifiers are basically fans that push polluted indoor air through a HEPA filter. There are quite a few advancements to this general model, but we didn’t expect below $200 would have any of them.
The 5-stage filtration system is definitely unexpected. 5 stages include prefilter, HEPA filter, antibacterial filter, activated carbon filter, and cold catalyst filter for formaldehyde.
As such, Okaysou filtration system is surprisingly well-thought-out. This is largely due to two factors:
The first one is the nature of HEPA filters. This is not an ordinary cheap HEPA filter; Okaysou uses exclusively medical-grade Ultra-Duo H13 HEPA filters (the best ones). There are designed to remove more than 99.7% of particles that are 0.3 microns in diameter.
In short, it can remove small dust, pollen, pet dander, smoke, odor, dust mites, mold, asbestos, even anthrax.
Here is a comparison of ordinary True HEPA filters and Okaysou’s Ultra-Duo H13 HEPA filters:
The second factor that makes Okaysou unique is choosing a HEPA filter based on your needs.
You can choose a HEPA filter that works especially well for:
- Pet allergies (white Ultra-Duo HEPA filter).
- Germ defense (blue Ultra-Duo HEPA filter).
- Toxin absorption (green Ultra-Duo HEPA filter).
- Odor removal (yellow Ultra-Duo HEPA filter).
You can see all types of HEPA filter you can choose from here:
Example: If you want to buy an air purifier to reduce the smell of cigarette smoke, you can choose the yellow Odor Remover filter.
If, on the other hand, you’re fighting mold infestation, the best Okaysou filter would be the green Germ Defense filter.
All in all, the filtration system is always the most important part of any air purifier. Okaysou has a superb HEPA filter, 5-stage filtration system, and you can even choose a HEPA filter for your specific needs. Overall, this makes the bigger Okaysou model one of the best H13 HEPA filter air purifiers.
CADR Rating And Coverage Area
The CADR rating is usually the most important metric when it comes to air purifiers. Okaysou air purifier’s CADR rating ranges from 125 for smaller AirMic4S to 300 for the bigger AirMax10L Pro Smart. In the middle – having the sweet spot of 210 CADR rating – is the flagship AirMax8L.
With that 300 CADR rating, the big AirMax10L almost made it to the list of the best air purifiers for smoke.
The coverage areas Okaysou recommends quite interesting. Producers usually want to write the biggest possible coverage area in the specification sheet; that’s why they use 2 air changes per hour (ACH) in the calculation.
Okaysou went beyond that standard and used ACH 3. Okaysour air purifiers are strong enough to change the air in a coom with a recommended coverage area three times per hour.
Example: Okaysou AirMax8L’s coverage area is 500 sq ft. That means that the air purifier will change all the air in the room every 20 minutes (or 3x per hour).
Noise Levels
No one loves a noisy air purifier. With Okaysou, given how little it costs, you might expect all that hard plastics will produce quite a lot of noise.
Not so, really.
The quietest Okaysou model is the flagship AirMax8L with 49 dB maximum noise levels. The big AirMax10L can reach 56 dB, it’s true. But that’s quite in line with other more known premium brands such as Medify Air.
In general, Okaysou air purifiers are unexpectedly silent.
With all that in mind, let’s look at individual specifications and reviews of the 3 air purifiers Okaysou makes:

Okaysou Air Purifier Stand Up To The Test
When we first wanted to review Okaysou air purifiers, the general opinion was that they couldn’t be good if they cost only $100 or so.
However, specs-wise, they are not only decent but quite exceptional. The price is so reduced because you don’t pay for a well-known brand, fancy design features, or advanced technology.
All in all, it’s not difficult to see why Okaysou AirMax8L is one of the best-selling and most popular air purifiers in 2022 and 2023. For all other information and potential Okaysou deals, you can turn to their official website here.
It’s not many times that such a distant price-performer comes to our desk, and Okaysou is a rare positive exception we had the pleasure of assessing.
Some other similar brands of air purifiers include Levoit, Winix, Honeywell, and Medify air purifiers.
