Okaysou AirMax8L 5-in-1 Filter Air Purifier – Review

If you are a regular visitor on our website and if you are subscribed to our articles, then you know that we have already written a review about Okaysou AirMic4s. And you know that this air purifier was not doing good in large rooms. Now we have put our hands on the successor of AirMic4s, so-called AirMax8L, which is proven as a much better option for a large room.

Okaysou AirMax8L Air Purifier

AirMax8L has five in one medical-grade filtration system. This model is one of the most popular as well as the best selling models from Okaysou company. The most significant advantage of AirMax8L is the large suction entrance, which allows excellent air circulation.

Okaysou AirMax8L Air Purifier

Okaysou AirMax8L has excellent airflow thanks to the unique design that allows that. With a medical-grade filter and five in one filtration system, this air purifier without a problem cleans the air in a large room.

AirMax8L is a much better option for a large room. And that power does not mean that you are not allowed to use it in a small room. In fact, in a small room, it will work even better.

Unique design with excellent airflow and an astonishing filtration system makes Okaysou AirMax8L one of the best buy options for a large room.

Design

This device has neutral white and black colors, which allows any room placement. You will not have any problems with placing this device even on a visible spot. High-quality plastic makes this air purifier durable enough to last for decades. 

If you like to use it as a mobile air purifier that is possible thanks to the handle on both sides. Airflow is one of the significant advantages of this model. A whole backside is an air entrance. This considerable air suction field allows this air purifier to perform great in a large room.

The only thing that I may say is not good about the construction is a short power cable. Keep that in mind when making plans, and maybe you should buy additional power cable.

Touch Buttons

Touch buttons work well, precise, and are sensitive enough to respond to even little touch. However, this air purifier does not have many exceptional functions, and because of that, you can only select basic options from the touch panel. 

Okaysou AirMax8L Touch Buttons

On/Off button is placed in the middle of the control panel. Simply press to turn the air purifier on or off. The sleep button is used to enter sleep mode, and the air purifier will make sure your sleep is not bothered. A timer button is a simple option that allows you to choose for how long you wish the air purifier to work. You can choose from 1, 2, 4, and 8 hours option. Fan speed button is used to select one of the three speeds at your disposal. The child lock button is crucial if you have kids that low to push buttons. When locked, you can be safe from kids messing up the options.

Be extremely careful not to drop small objects on top of the air purifier because beneath the protection grid is the motor. Any object that gets in contact with the motor may damage it.

Size and Dimensions

Size is an important factor if you have little space for new devices in your home. Okaysou AirMax8L (12.9 x 7.1 x 19.4 inch) is not large, and I am sure it will find a space in any room you want to place it. It will easily blend in the room. 13.75 pounds is not a lot of weight, and thanks to the handles on both sides, you can easily transport it from room to room.

Accessories and Parts

In the box, you will get an AirMax8L air purifier, one premium three in one HEPA, and antimicrobial filter, one premium two in one carbon filter with catalyst filter. User manual to make sure you do everything right at starting this device. Warranty card that allows you to get help in case anything goes wrong with your device.

Okaysou AirMax8L Video Review

In the video below, you can see more details about Okaysou AirMax8L. You can view all our test results; you can see additional tests we did as well hear additional opinions about this air purifier that are not written on this page. So make sure you watch this video before making a final decision.

Features

Three Fan Speed

The motor has the option to run on three speeds. If the air in the room is decent and you need silence, then the first speed is a good choice. The second speed is used to filter the air faster but still keeping the work at quiet enough grade. However, if the air quality in the room is terrible, you should put it on third speed and remove pollution as fast as it gets.

Okaysou AirMax8L will remember settings after turning it off, which means as soon as you turn it back on, it will continue to work with the same settings before shutting down.

Timer

A timer is a standard option on many air purifiers. It is a very useful option that allows you to run an air purifier for the desired time. On Okaysou AirMax8L, you can choose from 1, 2, 4, and 8 hours options.

Sleep Mode

The air purifier is silent enough on first speed, but if you need total silence, clicking the sleep mode will allow you that. You can sleep with the air purifier working without a problem.

Child Lock Mode

Child lock mode is useful if kids like to move around the air purifier. With child lock on, you can be sure no options will be messed up. It is also helpful if you have pets that may accidentally press buttons since the buttons are very sensitive.

Filter Replacement Indicator

A filter replacement indicator is one of the features that everyone loves to have. It is a great and simple way to make sure filters are replaced on time. Without this option, you will visually need to check filters, and even then, without experience, you will not know if the filter needs replacement or not.

Five Years Warranty

Five years’ warranty is a very generous gesture from Okaysou. This warranty only proves that this air purifier is made from high-quality material that will last. 

Advanced Silenceboost Technology

The turbine motor used in this air purifier with Advanced Silenceboost Technology reduces noise and makes sure the motor will run for years. Because of that, it is so easy to sleep with Okaysou AirMAx8L on, and because of that company gives a five-year warranty on this product.

For best performance, it is best to keep an air purifier 50 centimeters from the wall on all sides.

Certificates

This product is safe to use and has many certificates. CE, FCC, ETL, and CARB certificates make sure you get the best product. They also prove that this device is 100% ozone free.

Filter

This air purifier has two filters. Ultra Filter and Duo Filter. Ultra Filter is the primary filter which contains three filters. Duo Filter will clean air after Ultra Filter does its work. Duo Filter has activated carbon filter and Cold Catalyst Filter.

Okaysou AirMax8L Ultra Duo Filters

Filters are large, and that only means that filtration efficiency is large as well. However, to keep efficiency at the highest rate, you should replace filters every six to eight months. In case the air purifier is not starting, one thing you can check is the filter cover. If the filter cover is not sealed, the air purifier will not start.

Ultra Filter

This primary filter is responsible for removing airborne particles. Dust, pollen, mold spores, pet dander, pet hair, and other unwanted particles that a true HEPA filter can remove will be removed with this filter. The pre-filter is used to catch large particles like hair, large dust, or dander. The HEPA filter is the primary filter which removes most of the airborne particles. After the HEPA filter is Antimicrobial Filter, which makes sure no bacteria is growing inside the air purifier. It also removes a good deal of viruses, bacteria, and germs. 

Okaysou AirMax8L Ultra Replacement Filter

Ultra Filter removes 99.97% airborne particles that are freely floating in the air.

Duo Filter

Duo filter is placed after Ultra Filter. It consists of two filters, Activated Carbon Filter and Cold Catalyst Filter. The activated carbon filter is used to remove bad odors like cooking smells, farts, vintage smell, but it also removes smoke, wildfire smoke, and formaldehyde. Cold Catalyst can remove VOCs, ammonia, and hydrogen.

Filter Replacement

Filter replacement is easy to do, and everyone can do it on their own. Remove packaging from the newly bought filter. Open the back cover and remove dirty filters. Before you place new filters in the air purifier, make sure all the dust on the inside plastic or on the bottom is cleaned. YOu can use a vacuum cleaner or dry cloth. First, you need to place a DUO filter, and after that, add Ultra Filter. Make sure you follow the instructions and don’t make a mistake. Put the back cover back on, and the air purifier is ready for work. During the installation, make sure that the air purifier is not attached to the power. Also, make sure you don’t start it without a filter. After all filters are changed, you need to reset the filter replacement indicator by holding the sleep button for three seconds.

After every 1500 hours, the air purifier will send a siren, and the filter replacement indicator will light up to remind you that filters need replacement.

Noise

Since this is a large air purifier with a large motor, a louder sound during working hours is expected. We have tested it on all speeds. Sleep mode is also tested, and so far, we proved that it only switches air purifier to the first speed, and noise is not additionally reduced. As always, we use a noise measuring tool that rates sound on a dbA scale, which means our results and official ones may be different. Below, you can see the noise table.

Speed Value (dBA)
Speed 1 46.3 dBA
Speed 2 55.3 dBA
Speed 3 59.4 dBA

We have also performed various performance tests in different conditions. We can confirm that this device is working great in the recommended room size. However, it is also doing a decent job in slightly larger rooms. It is an excellent air purifier for medium to large rooms.

Okaysou has excellent results in large rooms and will make the air cleaner.

Results Conclusion

Okaysou AirMax8L has proven to be extremely beneficial in large rooms. We did not have the opportunity to test it in a larger room than 320 square feet. However, we believe that even in larger rooms, this device is useful. Even in rooms as large as 500 square feet, we think that without a problem, air can be improved. 

Operating Cost

The maximum power that his device pools is 50W. This number means that even if you run it 24/7, it will not cost a lot. If the air purifier works for 24 hours for one month at maximum speed, it will cost you 3.7$ if the power price is 0.12$ in your region.

Okaysou AirMax8L Air Purifier Review

However, on standby mode, this device uses no power. The highest maintenance cost is filter replacement, which needs to be done every six to eight months. Monthly operating costs are small, but when filter replacement is required, you will need to buy new filters.
