Okaysou AriMax8L Design

Okaysou AirMax8L

The Okaysou air purifier is the ideal size for medium and large sized rooms, up to 500 square feet. Enjoy clean, purified air with this powerful and efficient unit!

Located at the top of the purifier are all the regulating controls, while unfiltered air enters through filters on the front and purified air exits out of its peak.

To improve the air pressure and reduce noise output, this purifier uses a sophisticated wind wheel system that is connected to an air duct. This allows for maximum suction of more air with minimal sound.

The handle on both sides of the air purifier makes it easy to move around. Another great feature of this air purifier is the large airflow. The backside is open so more air can come in and the suction field is strong, which means it works well in a large room.

Okaysou model has the long power cable. This will help you place the air purifier a safe distance from walls and other objects. Another thing I like about this model is that it comes with an 8-liter tank, which means you won’t have to refill it as often.

Okaysou AirMax8L Features

Three Fan Speeds

This Okaysou model is equipped with three fan speed options, ranging from the whisper-silent first setting all the way up to a powerful second level. If your space has clean air circulating already, then simply opt for the first fan speed;

it’s perfect for those times when you need maximum peace and quiet. But if things are a bit stuffy in there, switch on the second mode — this will rapidly clear out any pollutants while still keeping sound levels low enough that no one notices!

If the air quality in your room is sub-par, then turn up the fan to its third speed setting and get rid of pollutants at an accelerated rate.


The Okaysou AirMax8L features a handy timer function, which gives you the ability to run your air purifier for as little or long as desired. You can select from 1, 2, 4 and 8 hour intervals –

once that time has elapsed the device will automatically switch off. This is not only an incredibly convenient option but also highly beneficial in optimizing energy efficiency!

Sleep Mode

AirMax8L air purifier is absolutely the perfect partner for a light sleeper like me! With its three-speed modes, including sleep mode, I can rest in peace. After clicking on the sleep mode button, this device quietly switches to the first speed and you won’t be disturbed while sleeping anymore. It’s such an amazing discovery that has made my life so much better!

Child Lock Mode

Child lock mode is an invaluable feature if you have children or pets who may accidentally press the sensitive buttons on your air purifier.

With child lock enabled, no settings will be changed and you can rest assured that any curious hands won’t disrupt your device’s performance.

Filter Replacement Indicator

I’m a huge fan of the filter replacement indicator, and I’m sure you’ll love it too—it’s an easy and convenient way to ensure your filters are changed on schedule.Without this feature, you would have to visually examine the filter, and even then it would take experience to determine whether or not a replacement is necessary.

Okaysou AirMax8L Filters

AirMax8L has two filters: the Ultra Filter and the Duo Filter. The Ultra Filter is the main filter and it has three parts: a pre-filter, a True HEPA filter, and an Antimicrobial filter.

The Duo Filter also has two parts: an Activated Carbon Filter and a Cold Catalyst Filter. These filters will remove different types of particles from the air. The Duo Filter will work after the Ultra Filter does its job.

Filters don’t come in small sizes; they are large, meaning that the filtration efficiency is also considerable. To maintain a high rate of efficiency, you must replace filters every 6 to 8 months.

Ultra Filter

The Ultra Filter is a primary filter that removes airborne particles, such as dust, pollen, mold spores, pet dander, pet hair, and other unwanted particles.

A pre-filter catches large particles like hair, large dust, or dander. The Ultra Filter includes a pre-filter, True HEPA filter, and Antimicrobial filter.

The True HEPA filter is vital for the removal of airborne particulates. This filtration system’s most important component, both in the Ultra filter and elsewhere, is no doubt the HEPA filter itself.

To make sure no bacteria are present in the air purifier, an Antimicrobial Filter should be utilized after the HEPA filter. With this powerful addition to your filtration system, viruses, germs and other contaminants are removed for a healthier breathing environment.

Duo Filter

Duo filter is a two-filter system consisting of an Activated Carbon Filter and Cold Catalyst Filter, which comes after the Ultra Filter. The Activated Carbon Filters primary purpose is to eliminate scents such as cooking smells, body odors, and perfumes but also effectively eliminates smoke particles from wildfires or formaldehyde.

Moreover, the Cold Catalyst Filter will remove VOCs (Volatile Organic Compounds), ammonia vapours or hydrogen that may be present in the air. With Duo filter technology you can have complete confidence knowing your home has been thoroughly purified!

Okaysou AirMax 8L Replacement Filter


The Okaysou AirMax8L is a perfect choice for medium to large rooms that require an air purifier. To add, I have conducted various tests to evaluate the performance of this product in different conditions and it has consistently impressed.

To examine the capacity of this air purifier, I conducted a test in two rooms of varying sizes. Room one was 194 sq.ft., while room two measured 320 sq. ft. The results were impressive and outlined below – it’s clear that the device is truly effective across different spaces!

Okaysou AirMax8L Power Consumption

AirMax8L boasts a maximum power of 50W, making it cost-effective and energy efficient when used for long periods.

If you’re looking to keep your air clean for an entire month, running the purifier at maximum speed will cost just 3.7$ with a power price of 0.12$. Now that’s 24 hours a day coverage for 30 days – what could be better?

Noise Test

With its powerful motor, the AirMax8L air purifier produces a louder sound than expected during operation. I put it to the test at all three speed levels and have compiled the following table outlining exactly how much noise is generated by this impressive appliance.

Speed Value (dBA)

Speed 1 46.3 dBA

Speed 2 55.3 dBA

Speed 3 59.4 dBA

After testing the sleep mode, I determined that when activated, it only lowered the air purifier to its lowest setting – yet there was still no additional noise reduction.

As usual, I use a noise measuring tool to gauge sound on the dBA scale. Because of this, my results may not always match up with official ones
