Critical Review of Okaysou Air Purifiers

Unique Filtration System

Okaysou boasts its unique filtration system. This is particularly true when it comes to its flagship Okaysou AirMax 8L, the most popular and widely-acclaimed unit among the collection.

Why is AirMax 8L so Popular?

The reason behind it must be its medical-grade Ultra-Duo filtration system and relatively low price tag. The unit has two filters—Ultra-filter and Duo-filter. The combination of a pre-filter, a true HEPA filter, and an antimicrobial filter works well in capturing large and small particles including various bacteria. And the odor and gas filter pack contains a honeycomb activated carbon filter with a cold catalyst filter layer. Sold at only $118.97, its performance is rather solid due to its unique 5 stages of purification. It is just as capable of removing 99.97% small particles as any other high-range air purifier.

All in all, less than $120, the AirMax 8L must be the king in the low-range market. Highly recommended!

On the other hand, Okaysou provides you different replacement filters to meet your need. Example: Okaysou AirMic 4S has a 3-stage Ultra-Duo filtration system. And for its H13 True HEPA, 4 alternatives are optional.

The medical-grade H13 filter is finely folded 130 times and up to 8000 cm² when unfolded. More importantly, the filter is only sold for $25 on average.

CADR Rating And Coverage Area

As an air purifier fan would know, the CADR rating is essentially the most important metric in this field. The higher the CADR is, the more effective the purification will be. That greatly explains why people prefer those air purifiers with a high CADR rating.

Okaysou is so sweet to offer three different air purifiers with different CADR ratings covering small and large rooms. The CADR rating ranges from 125 for the smallest unit AirMic 4S to 210 for bigger AirMax 8L to 250 for their big brother AirMax 10L.

To be honest, CADR rating is not the only factor that matters when it comes to the efficiency of purification. Room size also matters. If the room is large, of course, it will take longer to purify the air. That’s like a cliche. In this sense, Okaysou lists the biggest coverage, recommended size, and optimal size of all air purifiers in the product description. In addition, the air change per hour (ACH) rating is also listed.

Example: AirMax 8L can circulate air up to 5 times per hour(5 ACH) in an optimal room size (320 sq.ft.).

Noise Levels

Featured by advanced Silenceboost technology, all okaysou air purifiers can be counted as quiet ones when running at the sleep mode. The below pic shows the noise range of the AirMic 4S, that is, from 24dB(at the sleep mode) to 51dB(at the high speed). Here Atomee won’t say more, and the details will be listed in the following comparison table.

All you need to keep in mind is that Okaysou air purifiers are unexpectedly silent and won’t disturb your sleep.

Certificates

In addition to its solid performance, Okaysou air purifier also owns a bunch of certificates such as CE, RoHS, and ETL. What’s more, it is also compliant with California’s strictest safety standards(CARB). The stated goals of CARB include attaining and maintaining healthy air quality and protecting the public from exposure to toxic air contaminants. Therefore, if one air purifier is CARB certified, it must be a powerful device.

In general, Okaysou air purifier is a budget-friendly price-performance choice. One can barely find another duplicate in the market. Now without further ado, let’s have a look at each product.

1/3 Okaysou AirMax 8L

AirMax8L uses the unique Ultra-Duo Purification system, combining washable 3-Stage Ultra Filtration and 2-Stage Duo Filtration. 5 stages purification includes Pre-filter(for large particles), H13 True HEPA filter(for small particles), Antimicrobial Filter(for bacteria), Honeycomb Activated Carbon Filter(for VOCs and toxic substances) and Cold catalyst Filter(for formaldehyde).

The ultra-duo filtration system captures 99.97% of air pollutants like dust, pollen, smoke, pet dander and hair, household odors as small as 0.25 microns. In addition, the combination of the honeycomb activated carbon filter and cold catalyst filter can remove various harmful gases, such as formaldehyde, ammonia, benzene, and VOCs.

The exceptionally powerful purification makes the AirMax 8L have a competitive edge over other popular air purifiers in this price range. What’s more, its quality and efficiency are just as superior as those high-end counterparts.

Featured by a touch control panel, the AirMax8L, Atomee supposes, is the most beautifully designed unit. The control panel is at the top of the machine and has various different buttons to meet individual needs. One thing needing to be bragged about is that the setting won’t be changed once you activate the child-lock button. This button can prevent your kids or pets from pressing any others by accident.

2/3 Okaysou AirMic 4S

AirMic 4S uses 3-stage Ultra-Duo Filtration System to purify the air:

Washable & Detachable pre-filter: captures large particles such as dust, fibers, pet fur, and hair, and can largely extend the H13 HEPA filter’s life.

Home Medical Grade H13 True HEPA filter: removes 99.97% of airborne particles 0.3 microns in diameter, such as smoke, tiny dust particles, mold spores, bacteria, viruses, and allergens such as pollen, dander, and mites.

High-Efficiency Active Carbon Filter: absorbs stubborn and unwanted odors and fumes such as formaldehyde, ammonia, hydrogen sulfide, benzene, and volatile organic compounds (VOCs).

Sold at only $69.97, AirMic 4S really does its best to bring a fresh breath to you. The other two units with an even lower price tag popping into my mind are LV-H126 Personal HEPA Air Purifier ($59.99) and Honeywell HPA020B Tabletop ($62.60). However, compared with them, the smaller Okaysou unit still boasts its unique feature.

Though highly cost-effective, AirMic 4S never hesitates to use Medical Grade H13 True HEPA filters(the best ones). Besides, it is so sweet to provide 4 replacement H13 filters depending on users’ needs.

The unit is a compact air purifier for small rooms where the optimal size is 150 sq. ft (5ACH). Its cubic design makes it suitable for any corner of the room. The control panel is placed at the center of the top air outlet.

Though greatly cheaper than its big brothers, AirMic 4S also has a touch control panel just like the AirMax8L, except without a child-lock button. But if you have a limited budget and don’t want to sacrifice its high performance, this one is definitely the best bang for the buck.

3/3 Okaysou AirMax 10L Pro

AirMax 10L Pro uses 5-stage Dual-Nanois HEPA technology. Unlike traditional air purifiers, it boasts two HEPA filters which can capture 99.97% of air pollutants between 0.3-0.1 microns such as hair, pet fur, dust, pollen, smoke, and pet dander.

And for its unique advanced Blue Nano Ionic Silver Filter, it can decompose pollutants as small as 0.1 microns with eternal durability and the highest osmosis-action.

Honeycomb Activated Carbon Filter removes common household odors caused by pets, cooking as well as smoke caused by wildfires. And it also absorbs volatile organic compounds(VOCs) and toxic substances such as formaldehyde and benzene.

Compared with its precedents, the AirMax 10L Pro has a built-in smart sensor, which can give precise feedback in real-time. The elegant square LED light automatically displays your air quality and changes color from red to blue. The below picture shows the details.

In addition, AirMax 10L has four modes—Auto Mode, Eco Mode, Turbo Mode, and Manual Mode. Eco mode will stop working automatically for saving energy consumption when no pollution is detected within 30 minutes. Turbo mode is designed for high pollution conditions and runs the unit at the fastest speed.
