Air Purifier Benefits

Air purifiers can help protect you and your loved ones from air contaminants inside your house. Through filtration systems, these devices can separate harmful gases and particles from oxygen and facilitate the circulation of clean air across a room.

Having an air purifier active can drastically improve indoor air quality. They can help reduce unwanted odors, prevent allergic reactions, ease asthma-related worries, keep the air clear of pet fur, and more. Air purifiers can also catch airborne diseases and prevent sickness from spreading in your household. An air purifier can be an excellent investment for your health.

The AirMic4S Air Purifier Review

The AirMic4S’s main feature is its medical-grade H13 True HEPA filter. This allows the purifier to filter 99.97% of airborne particles, like pet hair, pet dander, dust, pollen, and smoke. It can also significantly reduce the volume of harmful gases and chemicals in the air, such as formaldehyde and ammonia.

Additionally, its filtration system cleans the air at least three times per hour, and it’s powerful enough to cover up to 300 square feet. This device boasts a SilenceBoost Technology, which allows for almost quiet, unobtrusive air purification.

Okaysou AirMic4S Design

Okaysou AirMic4S Air Purifier

The Okaysou Airmic4S can be described as simple yet elegant, with performance-enhancing design choices.

The purifier has a rectangular cube shape with smooth, rounded edges and a clean white finish. It sports a small Okaysou logo that indicates which side faces forward. On top of the unit is a large black vent with a small, digital user interface that houses all of the air purifier’s controls and settings.

The vent serves as a window that shows the inside of the unit. Through this vent, the main outflow fan can be seen. The entire chamber glows with a soft blue hue when the unit is turned on, giving the purifier a very sleek look when viewed in its entirety.

LED indicator lights can be found along the six main soft-touch LED controls on a panel at the center of the vent. With these controls, you can adjust the unit’s power, fan speed, modes, and more. The control panel’s minimalist design contributes to the AirMic4S’s elegant aesthetic.

The purifier’s filter is located at the bottom half of the unit, which can be accessed via the large cap screw-style hatch. This hatch can easily be opened and re-secured with a simple twist, making any internal maintenance or filter replacements trouble-free. The air intake grills are also found in the bottom half’s outer shell. You can easily access them if you need to manually wipe off dust or dirt.

How to Use the AirMic4S

Okaysou AirMic4S Air Purifier top fan

The AirMic4S has a simple control interface located on top of the unit. Each buttons on the panel will light up as you press them to indicate which ones are active. The power button is used to activate the purifier. Pressing the timer button on the middle-left side will let you cycle through 2H, 4H or 8H settings.

The fan speed can be adjusted by pressing the fan button on the middle-right side. The logos on the top-most part of the interface will light up, indicating what speed the purifier fan is currently running on.

The icon on the lower-left of the interface is a filter reset indicator that lights up when the filter needs to be cleaned or replaced. The lower-middle button activates the fan’s backlight, while the one remaining button activates sleep mode.

You can clean or replace the filters by opening the hatch on the underside of the purifier, but be sure to only use Okaysou filters for replacements.

Adjustable Fan Speed

The Okaysou AirMic4S has a selector switch that adjusts fan speed from Low, Medium, and High settings. This affects both air intake and outtake. Keep in mind that while a faster fan speed can allow for wider room coverage, it would also increase the device’s noise level will. However, the purifier’s SilenceBoost feature minimizes noise even when the highest fan speed setting is used.

Customizable Timer

The purifier can be scheduled to operate in specific intervals. Its programmable timer allows the AirMic4S to automatically shut itself down in 2/4/8-hour intervals. This is a great feature for power conservation.

Night Time Modes

The Okaysou AirMic4S comes with two modes that are designed to enhance nighttime experience: Night Light Mode and Sleep Mode.

Night Light Mode allows users to choose between two blue light settings that can create a more sleep-inducing atmosphere, while Sleep Mode pushes the purifier’s noise level to its lowest possible limit, allowing you a quiet night’s rest while maintaining air quality.

Okaysou AirMic4S Filter Types

The Okaysou AirMic4S can be equipped with four variants of the main H13 HEPA filter, all of which are medical-grade. The Ultra-Duo filtration system can help relieve symptoms of asthma as well as eliminate foul odors and smoke by blocking particles up to 0.3 microns small. The included filter variants are:

  1. Original Medical-Grade H13 Filter – This filter is designed to combat fine particles like dust and pollen. It’s also the filter of choice for dealing with cigarette smoke, pet odor, and more. It also comes with a washable pre-filter that can greatly extend its lifespan.
  2. Medical-Grade H13 Germ Defense Filter – This filter shares the same attributes as the original filter but with an added layer of defense against germs, making this the better option for rooms with high moisture levels.
  3. Medical-Grade H13 Toxin Absorber – This activated carbon filter specializes in dealing with gaseous toxins like fumes and VOCs. It also absorbs other manners of air pollution, such vehicle exhaust smoke. Like the germ defense filter, this variant also shares the same base traits found in the original medical-grade H13.
  4. Medical-Grade H13 Odor Remover – This filter excels in removing strong smells from cooking, pets, cigarettes, and more. It shares the same baseline features of the original filter but with a stronger emphasis on odor control.

Pre-filter and included H13 Hepa filter

Okaysou includes a washable pre-filter that serves as the first line of defense against air pollution and contamination. This pre-filter blocks larger air particles, like pet hair, fur, and dust. It prevents these particles from getting stuck on the main H13 filter, thereby increasing the filter’s lifespan. The filters are best replaced every 6-8 months.

Why is a HEPA-certified air filter important?

HEPA is an acronym that stands for High-Efficiency Particulate Air. A HEPA certification implies that a product is guaranteed to be effective in handling very small particulate matter. The US Department of Energy states that a filter must be able to maintain a 99.97% trapping efficiency level against particles that are at least 0.3 microns small.

This level of efficiency is essential for protecting a person’s lungs from harmful gas or particles. HEPA filters can prevent hazardous materials from causing serious or even fatal consequences.

HEPA-certified filters are commonly found in air purifiers and filtration systems in places like hospitals and factories. 

Okaysou AirMic4S Recommended Room Size

The AirMic4S’s CADR (Clean Air Delivery Rate) measures 125m3/h. This means that the air purifier can clean a 150 sq. ft. room in approximately 13 minutes.

You’ll be able to use the AirMic4S in any small- to medium-sized room with no trouble, but it’s not ideal for rooms that are larger than 300 square feet. While the AirMic4S has excellent purification capabilities and a robust filtration system, it is not powerful enough for large halls.

Okaysou AirMic4S Warranty

The Okaysou AirMic4S is a durable device. It can last for a long time if properly maintained. Its filters also have long lifespans, often reaching up to eight months before needing replacement.

However, if your AirMic4S breaks down due to technical issues, you can use Okaysou’s warranty offer. The Okaysou AirMic4S comes with a 5-year warranty. If your purifier stops working, simply ship it back and let Okaysou facilitate repairs for you. In the event that repairs are impossible, you can choose between getting a replacement model or a full refund. 

Okaysou Customer Support

Okaysou is a company that values their customers. Okaysou’s customer support team can be contacted via live chat on their website or by sending an email to support@okaysou.com.

What Are Others Saying About the AirMic4S?

Customer reception of the AirMic4S is impressively positive. Many users praise its extremely quiet operation and small size. Durability, design, and ease of use are other notable points that several users like. The integration of Night Light and Sleep Modes, in particular, are highly regarded as well.

The AirMic4S is even well-received by critics, citing the HEPA-certified filtration system as its strongest suite, although some reviewers noted that the purifier isn’t as good at blocking odors. 


What are the main differences between the KOIOS air purifier and the Okaysou air purifier?

The KOIOS purifier uses a 360° air intake chamber that captures more air than Okaysou’s 270° design. On the other hand, Okaysou offers a wider selection of filters and better quality-of-life features, such as a timer, a night light capability, adjustable fan settings, and the SilentBoost Technology.

What is the best place in your home for an air purifier?

Anywhere you spend the most time in is the most ideal room for your air purifier. Just make sure that it’s not obstructed by furniture while in use.

Which is better, a purifier or an ionizer?

A purifier is better in terms of sheer cleaning ability. Ionizers have lower operating costs than purifiers, however, and may serve as budget solutions.

Do air purifiers remove odors?

Yes, as long as it has an active carbon filter.

Does an air purifier use a lot of electricity to run?

Power consumption differs based on air purifier model. User manuals often indicate how much electricity a certain model uses.

Will an air purifier help with my asthma or allergies?

Yes. HEPA-certified purifiers would have a better chance of preventing asthma or allergic reactions.

How often should I run my air purifier?

Air purification is a continuous process. Purifiers should be turned on for as long as necessary.

Final Thoughts:

The AirMic4S is an excellent air purification system that we highly recommend. The simplicity of its design makes it very easy to use even with all of the features it comes with. Its automatic shutdown feature is great for saving power and money while its integrated night modes and Silence Boost make it more non-disruptive than other noisier options.

The user-friendliness of this air purifier makes it accessible to a wide range of people. Maintenance is easy, and operation is as simple as pressing a few buttons. The noise reduction feature gives the device an edge over many of its competitors.

The purifier’s true HEPA filter works exactly as advertised. Though it doesn’t quite block extremely strong odors, it still excellently filters out dangerous elements, like car fumes and cigarette smoke.

Okaysou’s dedication to serving their customers also adds considerable peace of mind. Though we’ve yet to experience any technical problems with the air purifier, it’s good to know that there’s reliable customer support for any product issue that might arise.

Overall, we highly recommend the AirMic4S. It’s a worthy investment for people who want a small but powerful purifier to improve air quality in their homes.
