Philips is a century-old brand from the Netherlands, a world leader in lighting, consumer electronics, home appliances and medical systems, and has grown to become one of the world's largest suppliers of medical devices and health appliances. As the main drafting unit of the new national standard for air purifiers, Philips' R&D strength has been widely recognized by the industry, and many of its products have been favored by consumers, ranking first in the domestic air purifier market share.
 
In 2018, the Hong Kong Consumers Association evaluated air purifiers, and Philips ranked first in terms of particulate matter CADR, formaldehyde removal performance and noise control, becoming the most recommended brand, and was selected as the "Smart Choice" by China Household Appliance Research Institute in 2017.
 
AC series is the main product line of Philips air purifiers, there are many models, with AC56 mid-range as the boundary, more than 56 is a high-end product, below 56 is the main cost-effective market, from the perspective of China's air pollution, Philips's mid-to-high-end models are more suitable for domestic consumers to buy, it is equipped with H12/H13 level HEPA filter, which is significantly better than the H11 level in the low-end model. The CADR value of particulate matter in high-end products is generally above 600, some models can reach 800, and the CADR value of formaldehyde is between 300-500, and the CCM value is also several times higher than the highest level of the national standard, but under the halo of IQAir, A.O. Smith, Samsung and other brands, Philips's comprehensive purification performance is not particularly outstanding, but it is definitely more than enough to deal with a variety of air pollution scenarios.
 
In terms of the detailed functions of air purifiers, Philips has also put a lot of thought into developing "Smart Sensing Technology" for its products, with a built-in professional-grade AeraSense laser sensor and algorithms to accurately monitor air quality. And the LED screen on the fuselage displays the value of pollutants such as PM2.5 in real time, Nightsenae light intensity detection technology is also very practical, when the external ambient light changes, it can automatically enter sleep mode, and the motor solution of Panasonic or SPG of South Korea can effectively control the noise level and reduce the impact on the user's sleep quality.
 
However, it should be pointed out that many Philips models use a carbon cloth composite filter element, which has the effect of "overclocking score" in testing the CADR value of formaldehyde, but it is more likely to fail due to absorption saturation. Therefore, consumers who need to remove formaldehyde should pay attention to the long-lasting purification capacity of formaldehyde, that is, the CCM value, in addition to the CADR value. In addition, many users in the southern region reported that some Philips models are easy to emit obvious sour smell when working, because the carbon cloth filter element is easy to get damp, and the filter screen after moisture is prone to incomplete decomposition of formaldehyde, and produces by-products such as formic acid, although it will not affect human health, but it is easy to cause sensory discomfort, so for consumers living in a higher humidity environment, the model of HEPA filter with independent activated carbon layer is a more suitable choice.
