Choosing the right air purifier can be challenging, especially with so many models on the market. This comparison looks at two popular choices: the Clorox Medium Room Air Purifier and the Coway Airmega 400S. Each model comes with a distinct set of features, performance levels, and price points. Here’s how they compare based on product descriptions and verified customer reviews.
Room Coverage
According to the product description, the Clorox purifier is designed for medium-sized rooms. It purifies rooms up to 225 square feet five times per hour and can clean rooms up to 1,000 square feet once per hour.
The Coway Airmega 400S is designed to clean spaces up to 1,560 square feet in 30 minutes, as stated in its product description. This makes it suitable for larger areas than the Clorox model.
Filtration System
The Clorox air purifier features a 3-stage 360° filtration system. The product description states it includes a pre-filter for large dust particles and pet hair, a True HEPA filter that captures 99.97% of particles as small as 0.1 microns, and an active carbon filter that reduces odors and volatile organic compounds (VOCs).
The Coway Airmega 400S, according to its product description, uses a HyperCaptive Filtration System. This system includes a pre-filter, deodorization filter, and True HEPA filter. It is designed to reduce 99.999% of 0.01-micron particles, as well as 99% of VOCs and odors.
Smart Features and Controls
The Clorox purifier includes an air quality sensor that provides real-time PM2.5 readings and color-coded light indicators. It also features an automatic mode that adjusts fan speed based on detected air quality, as outlined in the product description.
According to the product description, the Coway Airmega 400S offers additional smart functionality, including an app with indoor and outdoor air quality monitoring, scheduling, and filter alerts. It also works with Amazon Alexa. It has Smart Mode, which adjusts fan speed according to real-time air quality, Eco Mode for energy conservation, and Sleep Mode for reduced noise and power use when the room is dark and clean.
Noise Levels
Several Clorox reviewers commented on the purifier’s quiet operation. One reviewer said the fan was “not loud… not an intrusive noise,” and others echoed that the device was quiet even in larger rooms.
Reviewers of the Coway Airmega 400S also noted that the unit operates quietly, especially considering the volume of air it processes. However, one reviewer mentioned that it makes a “bing-bing” noise when switching modes, which they found potentially distracting.
Setup and Usability
Clorox reviewers frequently described the setup as easy and appreciated the automatic mode. One reviewer mentioned using the auto setting to manage air quality passively and found it responded quickly to changes in the environment.
Coway reviewers also noted ease of use, especially in cleaning the pre-filters and using the air quality indicator. Some, however, found the app’s alerts excessive and not reflective of actual air quality, leading one reviewer to disable the notifications.
Maintenance
The Clorox product description states that filters should be replaced every 6 to 12 months. One reviewer noted replacing the filter only once over the course of a year.
For the Coway unit, the product description mentions filter alerts that notify users when to replace or clean filters, based on how much air has been processed. Specific replacement timelines or costs are not included in the product description.
Build and Design
The Clorox purifier is described by reviewers as lightweight and easy to move. One reviewer reported using the purifier both on the floor and on a table, with no difference in performance.
Reviewers of the Coway Airmega 400S mentioned that it has a solid build. One review noted “heavy strong plastic sidewalls” and complimented the overall build quality. No details about weight or portability are included in the product description.
Summary
The Clorox Medium Room Air Purifier offers strong performance for smaller spaces, with a reliable 3-stage filtration system, real-time air quality monitoring, and auto-adjusting fan speed. Reviewers consistently praised its quiet operation and ease of use. According to the product description, it requires filter replacement every 6 to 12 months.
The Coway Airmega 400S, based on its product description, is designed for larger rooms and includes more advanced filtration that targets even smaller particles. It comes with a suite of smart features including app connectivity, voice control, and several automatic modes. While reviewers liked the build and performance, some found the app alerts excessive and noted occasional audible alerts that could be bothersome.
Each purifier meets different needs. For straightforward, effective air cleaning in medium rooms, Clorox provides good value. For larger spaces and tech-savvy users wanting more control and filtration power, Coway offers advanced functionality—at a higher price.
