Choosing between two well-reviewed air purifiers isn’t always easy—especially when both offer advanced features and solid performance. Here, we take a closer look at the Clorox Medium Room Air Purifier and the Coway Airmega 150 to help you understand what each model offers. We’ve broken down the key details using only the information provided in the product descriptions and customer reviews.
Room Coverage
The product description for the Clorox states that it is ideal for medium-sized rooms. It can clean the air in a 225 sq. ft. room up to five times per hour or purify air in a 1,000 sq. ft. room once per hour using its 360° airflow design.
The Coway Airmega 150 is designed to clean 214 sq. ft. in 12.5 minutes or 518 sq. ft. in 30 minutes, as stated in its product description.
Filtration System
The Clorox features a 3-stage 360° filter system. According to the product description, this includes an outer pre-filter to capture larger dust and pet hair, a True HEPA filter that captures 99.97% of particles as small as 0.1 microns and 99.9% of viruses and bacteria, and an activated carbon filter for reducing odors and VOCs.
The Coway Airmega 150 uses what it calls a HyperCaptive Filtration System, which combines a pre-filter, deodorization filter, and a True HEPA filter. The product description states it captures 99.999% of particles down to 0.01 microns, and reduces 99% of VOCs and odors.
Controls and Air Quality Monitoring
Both models include auto modes and real-time air quality feedback.
The Clorox offers a PM2.5 digital display and a color-coded air quality light ranging from green (good) to maroon (hazardous). The product description notes that auto mode adjusts fan speed based on air quality detected by the built-in sensor.
The Coway also includes auto mode and an LED-based air quality indicator, which updates in real time. The product description adds that you can turn off the light for sleeping. The Coway also includes a filter alert system that signals when to replace the filter or clean the pre-filter.
Design and User Interface
The product description for the Clorox mentions a 360° air intake and multiple manual control options, including fan speed, countdown timer, power, and LED display control. It does not describe the material or design in detail.
User reviews of the Clorox frequently describe it as lightweight and visually neutral. One reviewer noted it looked “unassuming yet elegant,” and others appreciated the responsiveness of the control buttons. However, one reviewer mentioned the touchscreen was “extremely sensitive” and could be triggered by wiping the unit clean.
The Coway’s product description highlights a cartridge-based filter design, intended to make filter replacement cleaner and easier. It also features a touch-sensitive display with controls for power, fan speed, light on/off, and filter reset.
Reviewers described the Coway Airmega 150 as having a minimalist and compact appearance. One reviewer mentioned it “looks really cool” and fits well in bedroom settings. The touch buttons were also described as responsive and simple to use.
Noise Levels
The Coway product description specifies a noise range from 19 dB to 48 dB, and reviewers described it as “really quiet” on lower settings. The Clorox product description does not include a noise specification.
However, reviewers consistently praised the Clorox for its quiet operation. One user noted that the unit runs “extremely quiet,” even when used 24/7, and another said it was “not an intrusive noise,” even on higher fan speeds.
Maintenance and Filter Replacement
The Clorox product description states that filters should be replaced every 6 to 12 months. It provides a model number for replacement filters but does not include information about maintenance costs.
Reviewers noted that Clorox filters are “a bit more expensive” than expected, but also mentioned they were “better quality.”
The Coway product description includes a filter alert system that tracks how much air the unit has processed and indicates when to replace or clean filters. It also notes that the cartridge design helps minimize dust during filter changes. However, it does not provide a specific filter replacement schedule or cost details.
What Reviewers Are Saying
Clorox users appreciated the ease of setup, effective air cleaning, and responsive auto mode. One reviewer mentioned the purifier helped eliminate smoke and odors during cooking, and another said it performed well in both small and large rooms. However, one reviewer shared a safety concern after the purifier’s efficiency prevented a smoke detector from being triggered during a minor kitchen incident. The same reviewer stressed the importance of ensuring functioning smoke detectors in other parts of the home.
Coway reviewers described the Airmega 150 as ideal for bedrooms or small offices, praising its quiet operation, design, and sensor sensitivity. One user noted that the air felt fresher and that lingering smells, like bacon after cooking, disappeared within hours. Another appreciated how the filter fit tightly in place and felt confident in the unit’s performance.
Summary
The Clorox Medium Room Air Purifier is more affordable and covers a wider area, making it a practical option for medium to large spaces. According to the product description, it offers thorough filtration, real-time air quality feedback, and automatic fan adjustments. Reviewers describe it as quiet and effective, though some noted that the touchscreen is overly sensitive.
The Coway Airmega 150 is more compact and slightly more expensive. The product description highlights its filtration efficiency and user-friendly design, including a cartridge-style filter system and real-time air monitoring. Reviewers praised it for its quiet operation and stylish look, especially in smaller rooms.
If you’re looking for a purifier for a larger room and want value, the Clorox offers a strong combination of features and performance. If your priority is a sleek, quiet model for a smaller space, the Coway Airmega 150 is a solid choice.
