Philips Air Purifier (Model #AC4014/10) Review: Philips AC4014 is a larger and taller version of the younger brother Philips AC4012 and ideally used in large living rooms or ideal for a one bedroom unit. We have got our hands on the air purifier AC4014/10 from Philips and here’s whats on offer.

ac4014_10Design: Philips AC4014 looks identical to its younger brother Philips AC4012 with all the design elements including the round corners, digital eye and other visual features. The device is a lot slimmer measuring 350X196X623 mm (W-D-H) and weighs at 6.1 kg. This makes it a little flexible to move the air purifier around different rooms of your house by holding the hand grip behind. The air purifier looks tall and may not be easy for everyone to move the device around, but, Philips AC4014 is ideally used in large rooms like the living room or can be ideal for a one bedroom unit. I also like the white color for its elegant look and the round corners elevate the visual appeal of the product. Philips AC4014 is offered only in white color, this is most probably due the ABS plastic construction material.

Controls and indicators are simple to use and read, the 3-step light indicators clearly show air quality level: Blue- good; Purple – fair and Red-bad.

TechnologyPhilips air purifier AC4014 is equipped with HEPA air filter, the mystery word HEPA which stands for High Efficiency Particulate Air. Glass fibers are used to make HEPA filters and their unique configuration makes sure that large contaminants such as mold, dust and allergens are captured. HEPA filters can collect 99.9% of airborne impurities that are larger than 0.3 microns diameter. It is important to know that HEPA filters do not deal with nasty smells or odors. Anyways, back to Philips AC4014, the device is equipped 3 stage air purification system, a pre filter, an active carbon filter and a HEPA filter. The pre filter helps to filter larger airborne impurities, the carbon filter to remove odors or gases and the HEPA to remove PM2.5 (Particles less than or equal to 10 micrometers in diameter, in simple terms, these are particles less than the width of human hair)

Sleep mode operates the device very quietly in dimmed lights. The healthy air protect alert lets you know when it is time to replace the filter with a timely warning.

The device also holds impressive test results of over 99% on purifying PM2.5 articles. In auto fan speed mode, the unit is silent at sound levels of 34dB, however, it gets a little noisy over 54dB at higher fan speeds. Customers have noticed inconsistent operation of the device is different cities, this is not at fault with the air purifier but due to climatic conditions. Weather in Mumbai is humid when compared to Delhi, humid weather causes moisture on the sensors making it inconsistent by indicating poor air quality even though the air quality is actually good. Constant cleaning of moisture with a dry cloth is required for the device to show accurate results.

Three stage filtration system consists of a pre filter that can capture big particles, an active carbon filter that can remove bad odors or harmful gases and the powerful HEPA filter can effectively remove PM2.5 particles (less than the width of human air)

Maintenance: Philips recommends periodic cleaning of the pre-filter when the device displays circle arrows on the screen, there isn’t a predefined interval as the filter life depends on the air quality.
