A Sleek and Intelligent Machine for Effective Air Purifying

The AirMax 10L Pro Smart Air Purifier–the largest and most powerful air purifier from Okaysou–utilizes an effective five-step filtration system to remove 99.97% of pathogens, odors, and allergens from the air.

It is perfect for those needing to purify larger areas of the house, including living rooms, family rooms, and basements. It can cycle through the air in a 1,000 square foot space in just one hour.

Are you looking for an ultra-energy-efficient purifier? Or something uber-effective at filtering out allergens and pathogens? Or maybe a machine powerful enough to remove the smell of burnt fish from your kitchen as fast as possible?

With various mode settings, including eco, turbo, and auto, you get it all with this one versatile machine.

While we love the sleek design that allows for easy placement along walls and behind furniture, you can’t escape the fact that this is a large purifier. If your space is smaller, you could easily do with one of the more compact Okaysou units.

Overall, the Okaysou AriMax 10L has many great features and provides powerful and effective air purifying, with very few drawbacks (the price of replacement filters being the most notable).


  • Powerful enough for large spaces
  • Multiple modes for every need
  • Super-quiet operation
  • Energy-efficient and EnergyStar rated
  • Sleek and intelligent design


  • Takes up a fair amount of room
  • Some filters are expensive to replace
  • No remote control capability

Should You Buy It?

Standing at just under 20 inches, this is a sizable unit. That mass gives it the power to purify large spaces quickly. If that’s what you’re looking for, then yes, this purifier is well worth the price, and you should buy it.

If you don’t need something quite so powerful, save a little money and space by purchasing one of the smaller Okaysou units.

Okaysou AirMax 10L Overview

okaysou airmax10L Filter capabilities

We have always been impressed with the performance of Okaysou’s entire line of air purifiers. But the AirMax 10L goes beyond our expectations.

This is a hard-working machine that looks and sounds like anything but.

The AirMax 10L is the most powerful purifier Okaysou sells. A large, 10-liter intake vent compartment, powerful fan, and redundant filtration mean this unit can purify over 250 cubic feet per minute. Or, in less technical terms, it can effortlessly purify a room of up to 1,000 square feet in about one hour. 

The AirMax uses a five-step filtration system to remove odors, smoke, pathogens, toxins, and allergens from the air. It is the perfect air purifier for anyone suffering from allergies or medical conditions aggravated by pollutants in the home.


The overall value of a product is a combination of its performance and usability. We are happy to report that the AirMax 10L scores almost as high in the usability department as it does in overall performance. 

It has five operating modes–auto, eco, turbo, timer, and manual–making it easy to customize its performance for exactly what you need. 

I find turbo mode especially useful before someone visits and after cooking disasters. With one press of a button, the purifier ramps up to its highest speed, quickly removing pollutants and odors. No more lingering burnt-egg smell in the kitchen!

In terms of upkeep, this purifier only needs occasional maintenance. The easy-read filter light will tell you when the filters need replacement. Most often, you can get away with just rinsing the washable outer filter.

The inner filters require less changing. But if they do need replacement, expect to spend a little money. The HEPA filters, especially, can be expensive.

Airmax 10L Noise Level

Some people like the white noise aspect of an air purifier. And some don’t. For the latter, this machine easily delivers.

The maximum noise level is 51 dBA, about the same as a whisper. Even running in turbo mode, this purifier is hardly noticeable in busier rooms such as the kitchen, office, and living room.

At lower fan speeds you can barely hear the machine at all. It is perfect for the bedroom if you are the type of person who can deal with a touch of white noise. But if you are hoping to use an air purifier to drown out your spouse’s snoring, this is not the machine for you.

Okaysou Energy Efficiency

When it comes to being eco-friendly, this purifier goes for gold. It meets multiple industry standards for energy efficiency and is EnergyStar, ETL, CARB, CE, and FCC certified.

The unit utilizes multiple biodegradable and earth-friendly materials in its filtration system. This is a huge selling point if you are concerned about keeping your waste to a minimum.

In addition to green filters, the eco operation mode automatically shuts down the unit when pollutants are no longer detected. This mode is perfect if you want the room’s air to be completely purified but don’t want the unit running all day.

This unit also features a timer function that allows you to set the run-time to 1, 2, 4, or 8 hours. I especially like this function for use in rooms that don’t get a lot of foot traffic. You can easily set your desired time, leave the room, and not have to worry about the unit running all day and wasting energy.

Air Purifying Performance

Of course, an air purifier isn’t worth a dime if it can’t effectively clean the air in your home. Luckily, that is one problem we’ve never had with an Okaysou unit. 

Like most of their products, the AirMax 10L eliminates 99.97% of pollutants from the air. It targets all particles down to 0.1 microns–which is about half the size of the smallest bacterium.

This stellar air purifying performance is achieved thanks to the five-step filtration process.

The first filter the air passes through is the washable “pre-filter,” which collects large debris like hair and dust. This layer is washable and reusable and will save you loads of money in the long run since the outermost filter typically needs replacement most often.

The second filter is the high-grade HEPA, which eliminates 99.9% of airborne allergens. This filter works in tandem with the third filter, the ionic silver filter that decomposes pollutants, to maximize pollutant removal.

The premium HEPA filter comprises the fourth layer of protection and further removes allergens and pathogens. Finally, the air passes through a honeycomb carbon filter that absorbs odors and harmful gases in the air.

This combination of filters is effective at purifying the air in even the stalest and stinkiest of rooms. But, maintaining prime effectiveness means having to replace the filters on occasion, which can get pricey.

Ease of Use

Getting started with the Okaysou AirMax 10L is as easy as plugging the unit in.

The control panel is intuitive and straightforward to use. If you are one of those people that doesn’t enjoy reading instructions, you shouldn’t have to worry about this purifier.

Another big plus in terms of ease of use is the sleek and smart design of this product.

Side air intakes mean you can place this unit along the wall without blocking airflow. But unlike similar units with a side intake design, the AirMax has two large openings on each side that feed to a single large capacity compartment. At the center of this compartment is the high-powered fan that pulls the air through the filters.

This design allows for maximum airflow and maximum flexibility in where you can place your purifier.

Overall, we were delighted with the performance of the AirMax 10L Pro Smart Air Purifier. You’d be hard-pressed to find another unit that is more effective, powerful, and versatile in this price range. Even with the pricier filter replacements and larger body design, we can’t recommend this product enough.
