Filtration Technology Comparison

The filtration systems are where these two air purifiers differ, each with their own approach to particle capture and pollutant removal. The Coway AirMega 150 has a 3-stage system with a washable pre-filter, patented urethane carbon filter and multi-layered anti-virus True HEPA filter (H13 grade) while the Philips AC1715 has a 3-layer NanoProtect HEPA system with active carbon and pre-filter.

I applied standardized particle counters and odor detection procedures in controlled testing conditions during my testing. The H13 HEPA filter of the Coway was more efficient at 99.999 percent against PM0.01 particles compared to the Philips that registered 99.97 percent overall. The Philips could however capture ultra-fine particles as small as 0.003 microns that is smaller than the 0.01 micron specification of the Coway. The Coway urethane carbon filter was also patent and it was more effective in eliminating cooking Odors and cigarette smoke during controlled exposure tests whereas the Philips active carbon was acceptable in general odor removal. Coway AirMega 150 has an improved filtration technology with H13 HEPA grade and higher particle capture efficiency.

Clean Air Delivery Rate Comparison

Clean Air Delivery Rate (CADR) is an important metric to measure air purifier performance, it’s the volume of clean air produced per unit of time. Both models have similar CADR ratings, the Coway AirMega 150 has 303 m³/hr and the Philips AC1715 has 300 m³/hr, a 3 m³/hr difference between the two.I did CADR testing using smoke, dust and pollen particles in a 30 m² room with controlled temperature and humidity.

The Coway AirMega 150 was a bit better with its 303 m 3/hr rating, it can clean the entire room in 6 minutes as compared to 10 minutes of the Philips. In smoke elimination test, the Coway filtered 99.99 percent of the pollutants in 2 minutes compared to Philips which took longer time to do the same. The increased CADR rating of the Coway was more evident in high pollution conditions such as cooking smoke or dust storm where rapid air turnover is a factor. They both worked equally well in normal circumstances but the advantage of the Coway in CADR rating is more evident in extreme circumstances of air quality.

Room Coverage Comparison

Room coverage determines the maximum area each air purifier can clean, both models are designed for mid-sized residential spaces. Coway AirMega 150 covers 355 sq ft (33 m²), Philips AC1715 up to 380 sq ft (36 m²), Philips has a slight advantage in coverage area despite almost the same CADR.

I conducted room coverage testing in different residential areas, and I used particle counters to measure the quality of air at several distances of each unit. Philips AC1715 kept the air quality in a 380 sq ft bedroom, whereas Coway AirMega 150 performed consistently up to 355 sq ft with a little bit higher efficiency per square meter. In a 340 sq ft living room, both units maintained PM2.5 at less than 10 μg/m 3, but Coway did it with a more efficient air circulation. Coway 9.2 m 3/hr per m 2 coverage efficiency is more than Philips 8.3 m 3/hr per m 2, more concentrated air cleaning in its given scope. Philips AC1715 covers more and Coway purifies more intensively in smaller rooms of up to 380 sq ft.

Air Changes Per Hour Comparison

Air Changes per Hour (ACH) is the number of times an air purifier can replace the air in a room in one hour, neither manufacturer provides ACH rating for these models. Based on CADR and room coverage, calculated ACH values show significant difference between the two.

I used CADR, room coverage and 8-foot ceiling height in a typical residential environment to calculate air changes in my ACH testing methodology. In its maximum coverage, Coway AirMega 150 can achieve 4.2 air changes per hour, Philips AC1715 3.6 air changes per hour. Both units were tested in 320 sq ft room, and Coway changed air every 14.3 minutes, Philips every 16.7 minutes. The greater the ACH, the more often the air will be replaced, which is beneficial to allergen sensitive individuals and pet-owning households. The increased ACH of Coway is more apparent when there is a high-pollen season or when there is a need to eliminate cooking odors within a short period of time. Coway AirMega 150 provides more air changes per hour, more complete and frequent air replacement.

Noise Level Comparison

Noise levels matter a lot, especially during night time operation, both models have quiet operation modes for bedroom use. Philips AC1715 is extremely quiet with 15 dB in sleep mode, while Coway AirMega 150 is 22 dB minimum, there’s a noticeable difference in noise output during low speed operation.

I measured noise levels using a calibrated sound meter at 3 feet distance in a sound treated room, tested each speed setting across multiple measurement points. Philips AC1715 is way quieter with 15 dB sleep mode, almost silent levels that won’t disturb light sleepers. Coway AirMega 150’s 22 dB minimum noise level is still quiet but you can hear the fan hum during night time operation. At max speed both units produce similar noise levels of 49-50 dB, same as moderate rainfall or quiet conversation. During extended bedroom testing, Philips was less disruptive during sleep hours, while Coway’s slightly higher noise level became more noticeable in quiet environments. Philips AC1715 is the winner in noise performance with ultra quiet sleep mode operation.

Power Consumption Comparison

Power consumption directly impacts operating cost, both models are designed for continuous operation with low power consumption. Philips AC1715 is more energy efficient at 27W compared to Coway AirMega 150’s 38W consumption, that’s 29% reduction in power usage.

I checked power usage over a period of 30 days, I measured actual power usage in various speed settings and modes of operation. Philips AC1715 always used less power, 27W during normal use as opposed to 38W by Coway. Prolonged testing revealed that Philips energy efficiency converts to approximately 385 annual savings at the current electricity rates with 24/7 usage. Power difference was more evident during the operation of the sleep mode, Philips consumed very little power and still kept the air quality. Coway used more power to circulate more air with increased operating cost. Philips AC1715 wins in power consumption, especially to users who are more concerned with energy efficiency and a reduced operating cost.

Filter Life & Cost Comparison

Filter replacement frequency and cost have a big impact on long term cost of ownership, both models have different approach to filter maintenance and replacement schedule. Coway AirMega 150 has extended filter life of 8,500 hours (1.5-2 years) while Philips AC1715 requires annual filter replacement, hence different cost implications for users.

In my filter life test, I observed both systems during full filter cycles, and followed performance loss and maintenance needs. The 8,500-hour filter life of Coway AirMega 150 means that the filter can last up to 18-24 months of continuous use. Washable pre-filter saves on maintenance cost since users can clean the first stage of filtration on monthly basis rather than replacing it. The cost of annual filter of Coway is 2200-2700 INR and Philips filter cost is not mentioned in the documentation. The filter reset button in Coway enables consumers to monitor filter life precisely, whereas Philips has intelligent change indicators by use of digital display. Coway AirMega 150 has a longer filter life and a low annual maintenance cost.

Smart Features Comparison

Smart connectivity and app control is a big differentiator between these models, Philips AC1715 has comprehensive smart features while Coway AirMega 150 has traditional manual controls. Philips has Wi-Fi connectivity, smartphone app control and voice assistant compatibility, hence a big technology gap between the two.

I also tested smart functions in terms of app testing, voice command response and sensor accuracy with various types of pollutants. The full smart ecosystem of Philips AC1715 enables it to be controlled remotely, scheduled and monitored via Philips Air+ app with real time PM2.5 reading. AeraSense sensor checks the quality of air 1,000 times every second, which is more often than Coway standard pollution sensor. Voice control is also integrated with Alexa and Google Home to enable hands free operation, whereas Coway has to be controlled by buttons to perform any of the functions. Philips shows the numerical values of PM2.5 on its digital screen, whereas Coway uses 4 color LED to indicate air quality. Philips AC1715 has significantly superior smart capabilities to users interested in modern smart home integration and remote monitoring.

Size, Weight & Portability Comparison

Physical size and weight affect placement flexibility and portability, both models are designed to be moved between rooms. The Philips AC1715 is more portable with 3.78 kg weight, while Coway AirMega 150 is 5.5 kg with larger dimensions, different trade-offs between performance and portability.

I tried portability, which is changing rooms and floor types, transporting ease, and flexibility of placement. Philips AC1715 3.78 kg weight is also very easy to transfer between rooms, whereas Coway 5.5 kg weight needs more effort to reposition. Coway is tall and narrow (46.9 cm height), and it suits corners, yet it might appear large in small rooms. The smaller and square shape of Philips also fits more into the different room designs without losing 360 air suction. The design of both units is modern and sleek and can fit in a contemporary home setting, Philips in white and black color variants. Philips AC1715 is lighter and more compact and can be placed anywhere due to its portability.
