Coway Airmega 400S:
71 Highlights & 61 Differences —
So, Which Air Purifier Actually Works Better
The Airmega 400 is a solid basic purifier, while the 400S offers more advanced controls and larger room coverage.
Which one’s right for you — Coway Airmega 400 or Coway Airmega 400S? We’ve compared their auto dimming display, model name, height & weight and more to help you choose the better air purifier.
Coway Airmega 400 vs. Airmega 400S: A Comprehensive Comparison of Two Tower Purifiers
Both the Coway Airmega 400 and Coway Airmega 400S are tower-style air purifiers manufactured in Korea that cater to medium to vast living spaces such as bedrooms and living rooms. Both models utilize HEPA filtration technology at the H13 grade, combined with activated carbon filters, to deliver clean, fresh air by trapping over 99.97% of airborne contaminants. They share a modern design aesthetic and similar physical dimensions, standing 22.8 inches tall with a 14.8" x 14.8" footprint, making them quite comparable in style and size. However, beyond these core features, the two air purifiers differentiate themselves significantly in terms of coverage area, filtration enhancements, intelligent connectivity, and safety features, offering distinct user experiences and capabilities.
Unpacking the Strengths of the Coway Airmega 400
The Airmega 400, released in 2018, is explicitly designed for rooms up to approximately 1,560 square feet. It boasts a solid filtration system with a 3-stage filter that includes a high-efficiency H13 HEPA filter and activated carbon to absorb odors and harmful gases. The unit generates a Clean Air Delivery Rate (CADR) of 416, reflecting effective purification across smoke, pollen, and dust particles.
This model operates quietly, with noise levels ranging from 22 dB at minimum to 55 dB at maximum, and runs efficiently at 66 watts of power consumption, maintaining the Energy Star rating of A++. Control is straightforward through touch and physical buttons placed on the top panel, although it lacks any remote or smart device integration.
It offers essential air quality monitoring through sensors for dust, odor, VOCs, and PM (particulate matter), with a real-time air quality display to keep users informed. The design also incorporates a slide-out washable filter with an indicator to notify when replacements are due, but maintenance requires some care since there are no tool-free options or cleaning aids included.
The Advanced Features and Smart Appeal of the Coway Airmega 400S
Stepping into a higher tier, the Airmega 400S, launched in 2016, distinguishes itself by supporting much more extensive coverage up to 3,120 square feet. It upgrades the filtration system to include a True HEPA H13 filter plus an added deodorization filter enhanced with antibacterial coating, designed to combat stubborn odors and microorganisms more effectively. Although the total CADR is not explicitly stated, this model supports maximum airflow rates up to 350 CFM, allowing for more rapid and thorough air exchange.
The 400S excels in user convenience and technology integration. It features multiple fan modes, including Low, Medium, High, Turbo, Auto, and even customizable settings, along with oscillation and airflow direction control for tailored air distribution. Noise output is noticeably quieter than its counterpart, rt with a maximum noise level of around 52 dB and an average of just 37 dB. This model boasts extensive sensor arrays measuring humidity, dust, VOCs, and other air quality metrics with a sensor accuracy rated at 95%, alongside an auto-dimming LED display that adjusts brightness in response to ambient lighting.
In terms of controls, the 400S supports touch and physical buttons plus remote control, mobile app connectivity, and voice assistant compatibility through Alexa and Google Assistant. The intelligent integration extends to firmware updates and IoT features with IFTTT support. Enhanced safety is also a major highlight with built-in overheat protection, tipover safety, surge protection, automatic shutoff, and power memory even after outages. Maintenance is streamlined with tool-free filter replacement and included cleaning tools. Environmentally conscious users will appreciate its use of eco-friendly materials, recyclable filters, and low ozone emissions.
A Quick Look: Which One Wins in What Aspect?
The Coway Airmega 400 shines as a reliable, robust air purifier that efficiently cleans the air in average-sized rooms with straightforward controls and essential filtration. Meanwhile, the Airmega 400S commands the space for those desiring premium features such as expanded coverage, smart home integration, superior safety protections, and advanced filtration technologies.
Closing Recommendation: Making Your Choice Between Airmega 400 and 400S
Suppose innovative features, extensive sensor data, and advanced safety certifications are crucial in your selection criteria. In that case, the Coway Airmega 400S emerges as the clear winner despite its higher price point, offering excellent value through cutting-edge capabilities and a premium build. Conversely, if you prefer a more budget-friendly option with strong purification performance and dependable operation without the bells and whistles of smart tech, the Airmega 400 provides an excellent option that covers typical home use efficiently.
Verdict
Winner: Coway Airmega 400S => Premium features, broader coverage, intelligent connectivity, enhanced safety, and eco-conscious design make it the top choice for modern homes.
Runner-up: Coway Airmega 400 => Offers solid filtration and good performance at a lower price, suitable for users seeking simplicity and reliability without connected features.
