[Bestbuy618 Home Appliance Channel]We frequently advise people to live a delicate life. In fact, this exquisite and natural beauty has nothing to do with wealth or poverty, but rather with a focus on life’s details and demanding requirements. People are concerned about the quality of outdoor air, but pay little attention to the threat of indoor air pollution. Because the doors and windows keep the outside world out, they also keep the bad air out.
In fact, indoor air pollution is the most severe. The average person spends 80 percent of his or her time indoors every day, not only in every moment and long-term latent formaldehyde, toluene, and other harmful gases, but also with allergens, viruses, and other indoor pollutants such as TVOCs, even kitchen fumes invade our breathing, the danger is everywhere and at all times. Beyond European standards, redefine good air Every country or region has its own indoor air standards, and European standards are widely regarded as among the most stringent in the world.
The current European requirements for indoor air are a formaldehyde concentration standard of 0.1mg/m3 and a PM2.5 concentration standard of 25g/m3.[i] While these standards are adequate, what people expect is always better. Recently, the industry leading brand Philips launched a new generation of air purifier AC3836, to redefine the standard of indoor air: to reduce the concentration of formaldehyde to 0.01mg/m3, 10 times better than the Euro requirements. In fact, this is not the first time Philips has updated air purification standards; previously, the Philips 5000 series air purifier was the first to reduce the size of filterable particles to 0.003 microns, which is 10 times better than comparable products.
So, can Philips air purifier successfully challenge the European standard this time?
Second, the performance test, which is the challenge of the real home environment. The performance test is divided into three main categories: PM2.5 test, formaldehyde test, and allergen test. Test site: a bedroom with a floor height of 2.8m, around 20 Test instrument: Braunton BR-V6E air detector Pollution sources: cigarettes, latex paint, fresheners, etc.
PM2.5 test The PM2.5 test was conducted first to see if the Philips Air Purifier AC3836 reduce the concentration of PM2.5 indoors to 0.01mg (10g)/m3.
The test site is a 20-person bedroom with a floor height of 2.8m, about the size of a typical household bedroom. During the test, all windows and doors were closed. Tobacco smoke is the simplest way to produce PM2.5 pollutants because the particles produced by burning tobacco disperse quickly throughout the room and are similar in diameter to PM2.5. The instrument used is the Bronton BR-V6E air detector, which can detect PM2.5, formaldehyde, PM10, TVOC, and other common indoor air pollutants.
After smoking two cigarettes, the PM2.5 pollution index in this bedroom skyrocketed to 875 g/m3, exceeding the national standard 8.7 times, indicating a serious level of pollution. The Philips Air Purifier AC3836 is very sensitive to PM2.5 detection and is the first to report red than our detector.
Its built-in professional-grade sensor measures air quality every 0.1 seconds. The Philips air purifier AC3836 can show the upper limit of PM2.5 is 500g/m3, at this time the indicator has been red.
Turn on the high speed mode and record the change of data on the air detector every 1 minute, organized into the following table. According to the national air quality PM2.5 index level standard, PM2.5 concentration value above 250g/m3 is called severe pollution, and 0-35g/m3 is excellent. We then opened the window, and the Philips Air Purifier AC3836 was still able to keep the indoor air PM2.5 concentration at 7-9g/m3.
Formaldehyde (HCHO) Test People are more concerned about formaldehyde than they are about PM2.5. One reason is that formaldehyde has a much longer latent period of release than PM2.5, and the other is that formaldehyde is more difficult to detect. Formaldehyde is the number one indoor killer, whether in an old house or when moving to a new one.
So, can the Philips Air Purifier AC3836 reduce formaldehyde (HCHO) concentrations to more than 2.5 times the European standard, i.e. The formaldehyde pollutant we chose was latex paint used for painting walls, opened the lid, applied to multiple corrugated sheets, and scattered and placed in multiple corners of the room to allow the odor to escape. After one night and eight hours, the formaldehyde content in the bedroom had reached 5mg/m3, exceeding the national standard by 50 times, and a pungent smell could be very clearly detected.
At the time, the gaseous pollutant index on the air purifier was L4, red, indicating severe pollution; similarly, we activated the Power Speed mode and recorded the change in data on the air detector every 1 minute to compile the table below.
According to a survey, the formaldehyde value of newly moved-in rooms can typically reach 0.28 mg/m3, which exceeds the national standard of 0.10 mg/m3. The formaldehyde content gradually decreases over time, but 0.08 mg/m3 of formaldehyde is still present after 3-4 years of residence. [ii] After about 6 minutes, the Philips air purifier AC3836 successfully reduced the formaldehyde concentration from a maximum of 5 mg/m3 to 0.01 mg/m3, the lowest scale we can show in this air detector.
As a result, this air purifier can achieve the purification effect claimed to be 10 times better than the European standard. Allergen test Spring and autumn are the most difficult seasons for people with sensitive bodies.
Spring pollen and willow metabolism, autumn grass metabolism, and year-round indoor allergens: pet dander, dust mite excrement, etc., and even perfume containing ether, fragrance, etc., can become allergens that cause itching and redness all over the body.
Three, better than the secret behind the European standard Philips air purifier AC3836 can exceed the European standard of purification, thanks to the two core technologies that Philips air purifier has been. The first is the Philips exclusive Micro Shield technology, which can purify up to 99 [iii] indoor pollutants and remove particles as small as 0.003 microns. It is a non-hazardous solution for PM2.5, hazardous gases, dust, and animal dander.
The Smart Sensor technology, with air sensors comparable to laboratory standards, constantly monitors air quality and dynamically adjusts the operation of the air purifier. Furthermore, this air purifier uses FY4150 composite filter, which is replaced by a cartridge from the previous square, increasing the air intake area and achieving a higher CADR value. Philips air purifier AC3836 is no exception; this air purifier is compatible with the “care about air” App.
After a successful connection, you can control the air purifier anytime and anywhere, turn it on and off, change the working mode, and check the air quality at home on the APP, comparing indoor and outdoor air quality. V: Appearance: subvert the traditional design, multiply the sense of sophistication Philips air purifier AC3836 a change in design, at first glance you will feel that this is not an air purifier, more like a speaker full of The use of textured fabric patchwork design, which is rarely seen on the air purifier this element, away from the mold of home appliances, placed at home as a furnishing rather than a simple tool. The main structure is divided into two parts, the bottom is a ring-shaped air inlet, increasing the area of contact with the air, and the top is the air outlet.
The top is outfitted with a TFT touch screen that can display the specific values of allergens, PM2.5, and gaseous pollutants in real time, and with four different colors, the user can specifically and intuitively know the current indoor air conditions. All the buttons are still touch design, in order to “filter status,” “digital display switch,” “power button,” “mode selection,” and “light,” and the panel light can automatically adjust the brightness according to the room ambient light changes, the night is not too harsh, very thoughtful.
Sixth: noise test When buying an air purifier, many people only focus on CADR (clean air volume) value, thinking that the bigger the better, the stronger the performance, and ignore the noise test. An air purifier that focuses solely on CADR without considering noise is a thug. It is simple to achieve high CADR if you ignore the noise, but such high performance is meaningless because you cannot leave a blower on 24 hours a day in the bedroom.
We measured the noise value of Philips air purifier AC3836 in sleep mode, auto mode, and power mode with a decibel meter in the bedroom where the ambient noise is 29.7dB and 1m away from the air purifier. The maximum noise level is 44.3dB in Power mode, what is this concept? The noise level of general indoor conversation is 40-60dB, so the noise performance in Power mode is still satisfactory. Sleep at night without having to worry about being noisy, and open at your leisure 24 hours a day, seven days a week.
The machine is also Quiet mark certified, which is a branch of the Noise Abatement Society, a noise control certification authority. To be certified and use the Quiet Mark logo, products must pass a series of sound and performance tests to demonstrate their high performance and quality.
Seven: Summary: A new theory of air purification With PM2.5 purification concentrations better than 2.5 times the European standard and formaldehyde purification concentrations better than 10 times the European standard, Philips Air Purifier AC3836 has completed a challenge to the stringent European standard.
[i] European standards refer to the WHO Indoor Air Quality Standards for Several Pollutants, WHO Europe, 2010 (WHO Guidelines for Indoor Air Quality: Selected Pollutants), which recommend that the safe concentration of formaldehyde for the general population is not higher than 0.1 mg/m3 and PM2.5 is not higher than 25 g/m3 [ii] Mei ZM Indoor formaldehyde pollution in new homes and how to avoid it [A]
