Main Features

The Okaysou AirMax8L is very impressive. This purifier has many handy features, including a medical-grade filtration system, advanced turbine motor, and adjustable three-stage or two-stage system. It also has several bonus features such as a child lock, sleep mode, auto-timer, and Silentboost technology.

Here’s a look at what these features offer:

Filtration System

The medical-grade ULTA duo filtration system serves to capture 99.97% of air pollution, such as dust or pollen, as well as dangerous gasses like ammonia, formaldehyde, or benzene. It can also neutralize odors as small as 0.25 microns in size.

Advanced turbine motor: With 45 vanes, it’s designed to take in as much air as possible and process it internally. In a 350-square foot room, the purifier circulates air 5x per hour. In an 800-square foot room, it circulates air 1.5x per hour.

Ultra- or Duo-stage System

The operator can select between a 2x or 3x filtration system to allow for faster or more intensive filtration.

Child Lock

This locks the control panel, meaning no wandering children will accidentally disable the unit or modify its settings.

Sleep Mode

The purifier runs quietly in sleep mode to allow for unobstructed rest. It also shuts off all of the lights on the unit.


This timer with shut the device off automatically at the end of the cycle. There are preset one-, two-, four-, or eight-hour cycles included on the panel.


Here’s a quick look at some of the AirMax8L’s greatest advantages:

Runs Very Quietly

This is one of the quietest air purifiers we’ve seen. It features a specially designed Silentboost technology. This purifier reaches a maximum of 22 decibels, which is a soothing lull at worst.

It’s perfect for use in the bedroom, home office, or living room. The last thing you want when you’re watching TV is a noisy motor running in the background. However, you don’t have to worry about that with the AirMax. 

Captures and Eliminates Pollutants

This system has a duo option, which runs on a 2x filtration cycle, or an ultra option, which operates on a 3x filtration system, allowing the user to select the optimal level of filtration. 

AirMax’s ability to capture and eliminate 99.97% of air pollutants is far and above the typical level of filtration featured on residential air purifiers. 

Reduces Odors

You don’t want to worry about odors or gasses when you’re relaxing at home. AirMax not only target pollutants but also breaks down bad odors and harmful gasses. This feature combined with the filtration system makes AirMax a great product for households with pets.

Versatile and Adjustable

This air purifier is a catch-all system. It works in the bedroom and the office. You can install it at your desk without annoying your neighbors. The auto-timer allows you to leave it running so you can ensure the air is clean when you re-enter a room. Plus, the duo and ultra options let you optimize the level of cleanliness.


Though this unit is very impressive, Okaysou’s air purifier has a couple of drawbacks:

Small Capacity

The purifier only cycles air through the room 1.5 times in areas up to 800 square feet. As a result, you’ll need to leave it running longer in a larger room.

Upsizing to a unit with a higher capacity will likely be a must if you want to use this device for your entire home.

Replacement Filters Hard to Come By

The unique replacement filters are effective but difficult to replace. A few customers have struggled to find replacement parts in their area.

What is the Okaysou AirMax8L Best For?

The Okaysou Airmax8L is a product with many faces. Although it’s designed to serve you best in the bedroom, it fits comfortably in any area of your home. This device makes it much easier to work in a quiet environment with clean and crisp air.

Other benefits of this unit include:

The AirMax8L is great for:

Sleeping Comfortably

This product removes odors and pollutants silently. The four- or eight-hour timer will ensure you a solid sleep in a breathable room.

Working Effectively

Its removal of annoying odors and particles can also help you work in your home office without distraction or obstruction.

Feeling Healthy

The AirMax8L’s removal of air pollutants and dust can relieve symptoms such as congestion, sneezing, shortness of breath, or runny noses, allowing you to feel healthy and comfortable in your home.

What Do I Need To Know Before Buying the Okaysou AirMax8L?

There are a few important things you need to know before buying an air purifier:

  • What is my issue?
  • How will this unit resolve my issue?
  • What are my other options?

For instance, an air purifier might not be the best solution for improving your air quality. A hot and sticky room would require a dehumidifier, while an influx of harmful gas could signal a much larger issue.

Here are the things an air purifier can do for you:

  • Purify the air

  • Capture and eliminate pollutants

  • Remove odors

  • Neutralize harmful gasses

  • Relieve symptoms such as congestion, runny noses, or sneezing

If you have issues with your home’s air quality, this is the right product for you.

How Do These Compare?

We threw Okaysou’s AirMax8L in the ring with other popular air purifiers to truly gauge its quality. Here’s how it looked when the final bell rang:

Alen BreatheSmart FIT50 vs Okaysou AirMax 8L

Alen Breathe’s Smart FIT50 is a great air purification system and well-designed. We’d probably go with the FIT50 if it came down to looks alone.

Alen Breathe’s product also has a 900-square-foot-coverage area and a smart sense system that detects and automatically adjusts to the air quality.

However, Okaysou’s product runs between 10 and 25 decibels quieter than the FIT50. This makes a huge difference at night. It’s also a more compact unit, weighing three pounds less and sitting four inches shorter.

Okaysou Smart AirMax10L Pro Air Purifier vs AirMax 8L

Okaysou’s Smart AirMax10L is essentially the bulked-up version of the eight-liter model. It can cover about 200 more square feet and features a few extra features. However, it’s more than twice as loud and takes up more space. Go with the eight-liter unit for your bedroom.

How to Use the Okaysou AirMax8L Air Purifier

The Okaysou AirMax8L Air Purifier is very user-friendly. It comes with a handy instruction manual and features some instructions on the box. The design of the control panel is also self-explanatory. We don’t think that you’ll have much difficulty using this product. 

However, to make things as easy as possible, here’s a quick overview of the process:

  1. Set up the unit. Make sure nothing blocks the intake or exhaust

  2. Plug the unit into an outlet

  3. Press the power button on the control panel

  4. Select the fan speed and filtration option

  5. Select the timer option

  6. Allow the unit to run

  7. Breathe clean and easy

When setting up the unit, make sure it’s sitting securely on the ground. It must be flat and stable to function effectively. You also want to make sure it runs without obstruction so the air can circulate.

How to Replace the Okaysou AirMax8L Filter

You should replace the filter in your AirMax8L once every six-to-eight months so the filter can function optimally. Failing to do so will result in a drop in quality.

An indicator light comes on when the filter needs to be replaced. Just remove the filter from the back of the air purifier and replace it. It’s easily accessible and the process is outlined in the manual.

Replacement filters can be purchased from Okaysou. OEM filters are recommended, as other filters may not fit the unit and could cause issues with purification.

You can also wash the filter. It’s made of a thin mesh that can be rinsed, vacuumed, or washed by hand. This will remove excess particles and allow the air purifier to run optimally. Okaysou recommends removing and washing your filter regularly.


The Okaysou AirMax8L is a highly effective, compact air purifier. It’s ideal for use in the bedroom and effective in other small- or medium-sized rooms. This is a great product.
