Price Comparison

When it comes to price, the PuroAir Air Purifier 100i is significantly more affordable than the Coway Airmega AP-1512HH. The PuroAir is priced at $74.99, while the Coway comes in at $229.99, making it about 66% more expensive. This considerable price difference may attract budget-conscious consumers looking for effective air purification without breaking the bank. However, the higher cost of the Coway could be justified by its advanced features and higher performance capabilities, appealing to those willing to invest more for quality.

Filtration Systems

The Coway Airmega AP-1512HH boasts a four-stage filtration system, which includes a pre-filter, deodorization filter, True HEPA filter, and Vital Ion technology, effectively capturing 99.97% of particles as small as 0.3 microns. This robust filtration system is designed for rooms up to 361 square feet, making it a solid choice for medium-sized spaces. In contrast, the PuroAir 100i features a three-layer filtration system that claims to filter 99.9% of pollutants, including dust, pollen, smoke, and odors, for areas up to 550 square feet. While both purifiers are effective, the Coway's additional filtration stage may provide a more thorough clean in smaller areas.

Coverage Area

In terms of coverage area, the PuroAir Air Purifier 100i outshines the Coway Airmega AP-1512HH, filtering spaces up to 550 square feet compared to Coway's 361 square feet. This increased coverage makes the PuroAir a better option for larger rooms or open-concept living spaces. For consumers with bigger areas to purify, the PuroAir can clean the air more effectively without needing multiple units, while the Coway may be more suitable for smaller bedrooms or offices.

Smart Features

The Coway Airmega AP-1512HH includes several smart features, such as an air quality monitoring system that provides real-time feedback on indoor air quality and an energy-saving Eco mode that activates when no pollution is detected for 30 minutes. Additionally, it has a timer feature allowing for automatic shut-off after 1, 4, or 8 hours. On the other hand, the PuroAir 100i offers Wi-Fi connectivity through the PuroAir app, allowing users to control settings and fan speeds from their smartphones. Although both purifiers have their unique smart features, the choice depends on whether you prioritize real-time air quality monitoring or app-controlled convenience.

Noise Levels

The Coway Airmega AP-1512HH operates quietly, with noise levels ranging from 24.4 dB to 53.8 dB, making it a great choice for bedrooms or quiet spaces. This ensures minimal disruption during sleep or work. The PuroAir 100i, while unlisted in terms of specific noise levels, is marketed as a quiet air purifier, especially important for those sensitive to noise. However, without specific numbers, consumers may prefer the Coway for its proven low noise operation.

Energy Efficiency

The Coway Airmega AP-1512HH has an energy-efficient design, boasting an ENERGY STAR rating while consuming only 77 watts of power. This efficiency translates to lower electricity bills over time, especially for consumers who plan to run their air purifier continuously. The PuroAir 100i also suggests an energy-efficient operation but does not provide explicit power consumption figures. For consumers conscious about energy use, the Coway’s clear specifications may give it a slight edge.

Brand Reputation and Awards

The Coway Airmega AP-1512HH has received notable recognition, winning the Best Air Purifier of 2018 from Wirecutter and ranking first on TopTenReviews. This establishes Coway as a reputable brand with proven performance in the air purifier market. Meanwhile, the PuroAir 100i was voted the best air purifier by Newsweek in 2025, suggesting strong performance as well. Both brands have established strong reputations, but Coway's longer history of accolades could provide additional consumer confidence.

Which should you buy?

Choosing between the Coway Airmega AP-1512HH and the PuroAir Air Purifier 100i ultimately depends on your specific needs and budget. If you have a larger space to purify and prefer a more budget-friendly option, the PuroAir offers excellent performance at a significantly lower price. However, if you are looking for advanced features like real-time air quality monitoring, energy efficiency, and a proven track record of success, the Coway may be worth the higher investment. Each purifier excels in different areas, making your choice contingent on what features matter most to you.
