Description

Whether you’re a pet owner looking to remove pet dander and odor, an allergy or asthma sufferer in need of relief, or you just desire improved indoor air quality, the Airmega 400S Smart Air Purifier by Coway is the air purifier for you.

 

Equipped with Wi-Fi integration, you not only have total control of the unit from anywhere on your smartphone or tablet, but real-time access to air quality levels and trends. Two-stage filtration, automatic operation, and 4 air changes per hour efficiently cleans 1,560 square feet areas with 410 cubic feet per minute (CFM).

Mobile Control + Alexa-Enabled 

With the Airmega 400S, you can monitor the unit via your mobile phone or tablet. If you have a Wi-Fi connection, you’ll be able to control your air purifier with the Coway IoCare App.

You can also control your unit and receive real-time air quality updates by syncing your model with your Alexa home device. Learn more information about setting it up to work with Alexa here

  • Instant Monitoring: Instantly know the quality of your indoor air and if improvement actions need to be undertaken with real-time testing of your air. Before you leave home, you can also monitor the outdoor air quality by finding out your locale’s pollution levels.
  • Control The Unit: By utilizing the app, you’ll be able to remotely control the purifier’s power, fan speed, timer, and air quality indicator light. The app’s scheduler function allows you to set the product to turn on or off at the same time every day.
  • Filter Notifications: When it’s time to replace the filters, the filter status alerts will let you know.
  • Reporting: Track your indoor air quality over a period of time ranging from just a few days to weeks. This is a useful tool in learning the air quality trends of your home.

Compact Design, Powerful Purification

At just under 23 inches tall, it’s smaller than other air purifiers on the market. A sleek black and white design makes it not only pleasing to the eye, but ensures it blends into your home. On the unit’s outer skin, the air hole pattern gets smaller as it moves up towards the top. The pattern reflects that air is pulled from the sides and cleaned as it moves upward.

Handles located on both sides of the product allow for easy lifting and moving from room to room. An air quality indicator light located on the front cover shows real-time indoor air quality. As air quality levels change, the light will change colors accordingly.

Two-stage filtration ensures that allergy triggers like pet odor, smoke, harmful gases, and other allergens are removed from indoor air. Filters are located on each side of the air purifier.

  • Pre-Filter: Whether pet hair, dust, or dirt, large particles will be captured by the pre-filter.
  • Max2 Filter: On each side of the air purifier are 2 combination filters. The Max2 filter is composed of a carbon filter to help eliminate 99.9 percent of volatile organic compounds (VOCs), and a Green True HEPA filter to capture 99.97 percent of harmful allergen particles down to 0.01 microns in size.
  • Remaining Filter Life Indicator: On top of the air purifier are 2 filter life indicators, the Pre-Wash and the Max2 Change buttons. Remaining filter life is displayed at 5 levels on the buttons (100, 80, 60, 40, and 20 percent). When the letters on the buttons are lit, the filters are at 0 percent and need to be replaced.

Smart Operation

Say goodbye to manually adjusting your air purifier based on guessing. When set to Automatic Mode, this smart air cleaner provides the epitome of user-friendly operability.

  • Fan Speed Adjustment: Constantly monitoring your air quality, the unit will automatically adjust the fan speed to 1 of 3 speeds based on its readings.
  • Sleep Mode: When the room is dark and the air has remained on the Good level for 3 minutes or more, the purifier’s light sensor will reduce the purifier’s power and noise.
  • Eco Mode: To conserve energy, the smart purifier’s fan will turn off when air pollution levels have remained Good for 10 or more minutes. If the quality worsens, the fan will automatically turn back on.

Ultra Quiet Construction

Common sources of air purifier noise are high fan speeds and noise produced by air exiting the unit. Airmega by Coway has reduced fan speed to make the Airmega 400s Air Purifier no louder than a quiet conversation on its highest speed. To prevent a low fan speed from reducing cleaning effectiveness, fans are located on both sides of the product. Larger air vents further reduce noise levels by limiting the noise caused by air leaving the air purifier.

Pick the Best One for Your Space

More than just functional, the Coway Airmega 400S is stylish too. This powerful air purifier is available in 2 colors, white and graphite.

Additional Features

  • Timer: The timer button located on the control panel can be used to program the purifier to turn off after an hour, 4 hours, or 8 hours.
  • Light Button: Use to turn the air quality indicator and light on or off.
  • Protective Covers: Plastic covers protect the unit’s filters and pollution sensor.
  • Air Outlet Cover: Ensures the fan remains damage-free.
  • Color Options: Available in your choice of fresh white or classic graphite.

Sylvane's Expert Take

Improve indoor air quality in spaces up to 1,560 square feet with the Wi-Fi-enabled Airmega 400S.

What Customers Love

  • Wi-Fi Integration: Have complete control of the unit directly from your smartphone or tablet. Turn on the power, adjust fan speed, check air quality, monitor filters, and track indoor air quality over time.
  • Hands Off Control: With essentially automatic operation, this air purifier takes the guesswork out of trying to figure out when indoor air needs to be cleaned.

Things to Consider

  • App Download Required: Before you can pair your phone or tablet to the air purifier, you must first download the Airmega app from the Apple App Store or Google Play Store.

    It Works Well and Looks Great Too!

    I'm very pleased with this model. It does a great job clearing the air in my 800 sq ft condo. It's fast, efficient, and I love the app that I use to control it. It stays on in ""Smart"" mode constantly. I can't think of anything that could be done to improve this machine.
