Okaysou is just a new air purifier company, launched in 2018. In a short duration, they’ve managed to raise a good reputation on Amazon, with lots of dedicated contributions for air purifier knowledge. The Okaysou AirMic4S is their latest air purifier, to serve for a much lower-range segment than the ace Okaysou AirMax8L. Is it good? Let’s find out in our Okaysou AirMic4S Review.

Okaysou AirMic4S Price

Okaysou AirMic4S, as the name suggests, is a compact air purifier for small rooms. Okaysou was one of a few Chinese companies to name their product properly, instead of giving random number for the products (like Elechomes, Inofia or Partu).

It’s an air purifier to compete directly against the phenomenal success of Levoit LV-H132 and its successor – the Levoit Vista 200. The Okaysou AirMic4S boasts about its H13 True HEPA filter, which can even be customized like the more expensive Levoit Core 300.

This isn’t a surprising move, as Okaysou did exactly the same thing when they introduced the Okaysou AirMax8L, to borrow high-end specs for a really cheap device.

So what do you get with the second generation of Okaysou air purifiers. The Okaysou AirMic4S costs officially $89, and you should check our deal for the lowest price. In short, it is equivalent with the price changes from Levoit.

At that price, the Okaysou AirMic4S is competing against Airthereal ADH80 and many Chinese air purifiers like Elechomes EPI236 and Mooka Allo. You should read the reviews carefully before pulling the trigger.

Okaysou AirMic4S Design and Size

Okaysou AirMic4S follows the design language of this company, though for more compact air purifier, it isn’t identical to its big brother. In my opinion, it is the best-looking device the company has made to date. It is the cubic design, but it has a more rounded design than any cubic air purifiers you’ve seen in the market.

For the dimension, Okaysou AirMic4S is just 12 inches in height and 8.7 inches in width. It is so compact that you can put it tabletop easily, and thanks to the Nightlight function, it could be perfect on a nightstand.

In fact, the design of Okaysou AirMic4S isn’t distinctive, but it has a premium-looking and feeling with main white tone color on plastic body. It doesn’t look out of place alongside other air purifiers which cost more. Considering the comfortably cheaper price, it’s rather impressive.

Okaysou AirMic4S runs a bottom-to-top air flow system concept, but it doesn’t have 360° air intake, but only two air grills from both sides. That’s quite a disappointment for an air purifier with cylindrical air filter, but perhaps Okaysou didn’t want to change their common design language.

The top control panel is placed at the center of the top air outlet, which is really like the higher-range Levoit LV-H133. The touch control is simple to read and use.

Okaysou AirMic4S Filters

Okaysou once again stay firm with making only air purifiers using mechanical filters. The Okaysou AirMic4S uses a simple 3-stage air cleaning system.

  1. Pre-filter – The washable pre-filter can capture large particles such as dust, pet hair and fur, to protect and extend the main filter’s life.
  2. True HEPA filter – Traps 99.97% of any particles as small as 0.3 microns, like pollen, mold spores, pet dander, dust or dust mites. It is a H13 True HEPA filter, so it can even capture the particles as small as 0.1 microns.
  3. Activated Carbon filter – Adsorbs cooking smell, pet odors, ammonia, benzene and Volatile Organic Compounds (VOCs).

Although Okaysou AirMic4S uses an all-in-one air filter, the pre-filter can be detached and washable, therefore extend the main HEPA filter’s life much better.

Obviously, as a more budget device, the Okaysou AirMic4S only uses carbon cotton filter, instead of honeycombed carbon filter like the flagship Okaysou AirMax8L. However, the big headline power is the H13 True HEPA filter, which can reduce even the particles as tiny as 0.1 microns.

Now it’s time for a real test. The Okaysou AirMic4S is tested in the same conditions as many great budget air purifier options like AeraMax Baby DB5, hOmeLabs or RENPHO RP-AP068: in a room of 100 square feet and continuous running in 1 hour. As you can see, the efficiency of trapping any particles down to 0.3 microns of Okaysou AirMic4S is really good, as it can score 99.7%, the same as the popular Levoit Vista 200.

Okaysou AirMic4S Room Coverage

The most welcome feature of the Okaysou AirMic4S is it keeps the competitive fan power from its big brother. Okaysou AirMic4S is recommended for a room of 288 square feet, and the manufacturer ensures that with appropriate air flow, you can run this air purifier in 576 square feet.

The ACH of Okaysou AirMic4S is 2X to 4X. For this air purifier to exchange the air in your room every 15 minutes, it should run in only area of 144 square feet.

The CADR of Okaysou AirMic4S is 74 cfm in general. This CADR rating is truly competitive, especially when Okaysou keeps selling this air purifier on lower price.

Okaysou AirMic4S Sound

As a portable air purifier, the Okaysou AirMic4S is designed for bedroom and nursery’s use. One of the main advantages for using lower fan power is the obvious low noise level. Okaysou AirMic4S uses an advanced turbine motor with streamlined vanes, and it keeps the noise level at 24 decibels (db), even better than the whisper.

On highest speed, the noise level is only 51 decibels, and it just generates white noise. This is just the noise level of a fan from 100 square feet, and it can’t disturb you on sleeping or working.

Okaysou AirMic4S Power Consumption

One of our most FAQs is “Do air purifiers use a lot of energy?” In fact, air purifier must be used for a long time to be efficient. And power consumption is one important criteria to review if this air purifier is good or not.

Okaysou AirMic4S stores a rated power of 25 watts, with the standby power less than 0.5 watts. You can enjoy the high-quality air cleaning system without costing much.

If you run the Okaysou AirMic4S for at least 8 hours per day, you only need to pay $9 each year.

Okaysou AirMic4S Additional Features

The Okaysou AirMic4S is truly a head-to-head competitor with the Levoit LV-H132, so it isn’t a surprise to see the Nightlight function and Sleep Mode as the main selling points of this air purifier. You can select between two blue light settings, and if you are sensitive to the light, you can easily turn it off.

Okaysou AirMic4S further assists in bedroom with a convenient Timer, to schedule the time off for 2, 4 or 8 hours. And the company isn’t stopping there, as Okaysou AirMic4S has a LED indicator for filter replacement.

Our verdict

Just like many other Chinese manufacturers, the Okaysou AirMic4S is perhaps an air purifier didn’t need to make to reach higher-range users, but they did it to stabilize the market share on budget segment. If you want an improved experience from a small business like Okaysou, it may take years.
