Filter resolution Testing purposes: Different quality filters will have different purification effects. Many times consumers think that the bigger the machine is, the heavier the filter components are, the higher the standard, the better the purification effect will be. What is the truth? We will Contrast the filters of five air purifiers. But here, I also suggest that when choosing an air purifier, besides choosing a professional brand, you also need to pay attention to the material and weight of the filter. These are all related to air purification. Filter effect can not be ignored. Philips Air Purifier AC5660: Philips Air Purifier AC5660 can effectively clean PM2.5 for 72 square meters of room, remove formaldehyde, allergens, bacteria and viruses. It is like an invisible umbrella, protecting your health and your family at all times.   Open the cover of the air inlet, you can find a professional S3 nano-thickness filter weighing 1.1KG. The filter can be fully expanded to 2.2 square meters. It is worth mentioning that the Philips AC5660 air purifier used Double-sided composite filter, compared with the traditional filter, it can effectively purify a variety of pollutants, bringing a unique purification experience.  It is worth mentioning that the Philips Air Purifier AC5660 deliberately uses a 5-layer filter, in addition to conventional harmful substances such as viruses, allergens, etc., can also block larger dust and hair, and then pass the HEPA filter to filter out PM2 .5 As small as 800 times finer particles, it is finally absorbed by activated carbon filter to remove formaldehyde, toluene and other harmful gases. Through such layer filtration, it is truly purified and brings fresh and healthy air to the interior. This type of composite filter has been adopted by more and more manufacturers. Compared with the traditional filter, the composite filter can effectively increase the probability of the attachment of contaminants, and has a significant improvement in noise control.  Take out the strainer lightly and you can see the double-strength centrifugal fan just mentioned above. The perfect aerodynamic design can discharge strong airflow. This is also the CADR value of this machine's particles can reach 600m/ One of the important reasons for h.

practical testing The actual measurement of the air purifier has always been the focus of the evaluation. In this actual measurement session, we will conduct a total of four indicators testing on the air purifier, and finally judge the pros and cons through comprehensive assessment. Note: All the links in this test are non-laboratory environment and there may be errors. The test data is only for consumers' reference. Test one: PM2.5 removal experiment Testing purposes: As a key indicator to measure the performance of air purifiers, the clean air volume CADR represents the strength of the air purifier's purification capability. The higher the CADR, the faster the purification rate. In fact, there is a misunderstanding in the interpretation of the clean air volume CADR, not the clean air volume CADR. The higher the better, the amount of clean air CADR is related to the space that needs purification. If the space is small, the clean air amount CADR does not need to be too large. As the most important standard in the new national standard, the purification capacity is naturally this time. The actual measurement, so we actually test the purification capabilities of these five air purifiers. Test Methods: The air purifier was placed in a sealed transparent box of 2m3. After burning one cigarette, the PM2.5 value in the box was monitored in real time using a helium-measuring device, and the records were compared. Philips Air Purifier AC5660: We placed the Philips Air Purifier AC5660 in a special transparent Perspex test chamber. The actual test space is about 2 cubic meters.  In the box, we ignited a cigarette as a simulated pollutant. After about three minutes or so, the cigarette burned down. At this time, the box was filled with PM2.5 smoke.  We put the air quality detector into the test chamber. In less than 5 seconds, the PM2.5 value on the detector rose to the peak of the instrument 999.99μg/m.3!  Then we opened the Philips Air Purifier AC5660, at which point the machine detected severe contamination and the color was red.  The wind speed of the Philips Air Purifier AC5660 was adjusted to the maximum strong mode, and the detector's value began to decrease in approximately 10 seconds. After approximately 10 minutes or less, the detector value finally dropped to 0 μg/m.3.  Sharp Air Purifier FP-WH70-W: Let's take a look at the PM2.5 removal test of the Sharp Air Purifier FP-WH70-W.  1. Place the Sharp Air Purifier FP-WH70-W in a sealed, transparent box of 2 square meters to light cigarettes inside. After approximately 3 minutes, the cigarettes are burned out and the internal PM2.5 value of the cabinet is detected through the scratch meter. In less than 10 seconds of data monitoring, the reading of PM2.5 on the instrument soared to the peak value of the instrument, which was 999.99μg/m3. The table had been exploded, and the breathing lamp was shown to be heavily polluted.    2. Start the purification function of Sharp Air Purifier FP-WH70-W, start recording the PM2.5 value of the interior of the box, about 10 seconds later, the value of the meter will start to decrease, and the breathing lamp will show yellow, after a period of time , Decrease to 0μg/m3, the breathing light is shown in blue, the air is purified.    Breathless Air Purifier: According to the official website data, the Smart Air Purifier's cleansing power is strong. The CADR value of particulate matter is as high as 800+m3/h, the CADR value of formaldehyde is as high as 300m3/h, and the particulate matter CCM value is 50,000mg, which is 4 times the highest level of the national standard. Above, the formaldehyde CCM reaches 2 times the highest level of the national standard; its HEPA filter particle size of 0.3 microns or more, a single filtration efficiency of 99.97%.  Just look at these may be more abstract, below we use a video to visually see the PM2.5 filtration process of the hammer breathing air purifier. We placed the hammer breathing intelligent air purifier in a closed room, and then ignited a cigarette. After the cigarette smoke fills the entire room, the PM value is measured. The average data for the 60 seconds sampling is PM2.5 up to 246 ug/m3 and PM10 up to 480 ug. /m3, The pollution is very serious.  At this time we opened the air-breathing purifier, turned on the automatic mode, the purifier display turned red, and began strong operation.  After 5 minutes of decontamination, the PM2.5 in the room dropped to 11ug/m3, PM10 dropped to 22ug/m3, and the value displayed on the hammer-breathing air purifier was 8. The purification process took about 10 minutes. About 10 square meters.  Panasonic Air Purifier F-PXP155C: We placed Panasonic Air Purifier F-PXP155C in a special transparent Plexiglas test chamber.  In the box, we ignited a cigarette as a simulated pollutant. After about three minutes or so, the cigarette burned down. At this time, the box was filled with PM2.5 smoke.  We placed the air quality detector in the test chamber. In less than 5 seconds, the PM2.5 value on the detector rose to the peak of the instrument 999.99μg/m3!  Then we opened the Panasonic air purifier F-PXP155C and adjusted the wind speed of the Panasonic air purifier F-PXP155C to the maximum strength mode. After about 10 seconds, the detector value began to drop. About 20 minutes, the value of the detector was finally Drop to 0μg/m3.  Mori Chen MCW1 Air Purifier: 1, first of all, we measured the monitoring data in the box at the initial state, which was 35.2μg/m3.    2. We used cigarette lightening to make the box full of smoke. We ignited a cigarette. After about 2 minutes, the cigarette was completely burned. The data was measured with an air quality monitor at 999.99μg/m3. The instrument showed a burst table state. And our air purifier at this time the panel display is also very accurate, PM2.5 is in a poor state. Under this product's dual sensor monitoring, after the exceed standard Symphony streamer lights automatically rise and switch to red to alert the user. Intelligent adjustment to the maximum gear, quickly purify the air environment.    3. Then we turned on the high air volume mode of the air purifier, and a strong circulating air flow was generated in the cabinet. After about 10 seconds, the value of the test instrument began to drop. After a while, the instrument value finally dropped to 0 μg/m3. .
Test item two: wind speed test Testing purposes: The purification efficiency brought by different wind speeds is different, and the wind speed is also closely related to the noise. Therefore, the test of wind speed has always been one of the standards for the evaluation of air purifiers. Test Methods: In the wind speed test section, an anemometer is used to sample the wind speed data for the different positions of the purifier (taking the maximum value of each gear). Philips Air Purifier AC5660: First, in the sleep mode, the maximum wind speed measured at the top of the aircraft was 3.53 m/s.  After that, we adjusted the air speed of Philips Air Purifier AC5660 to the maximum, and the measured wind speed was 6.32m/s. To be popularized with everyone, the wind speed of about 6m/s has already reached the wind class 4 and can be easily blown on the ground. Dust and paper.  Sharp Air Purifier FP-WH70-W: Then, we tested the wind speed of the Sharp Air Purifier FP-WH70-W at the outlet. We tested with the weak wind, mid-range, high-end and sleep modes respectively. Weak wind speed test: We placed the anemometer at the air outlet and collected it after several movements. The maximum wind speed measured at the top of the machine was 3.21 m/s.  Wind stroke mode wind speed test: The wind speed measured by the above method is 7.04m/s.  Wind speed test: The wind speed measured by the above method is 9.57m/s.  Sleep mode wind speed test: The wind speed of 3.02m/s was measured by the same method, because the sleep mode creates the best sleeping environment for the user and does not affect the user's daily life.  Breathe smart air purifier: We tested the wind speed of this breathless smart air purifier outlet. In the low air volume mode, we placed the anemometer at the main outlet and after several movements to collect data, the maximum wind speed measured was 0.9m/s.  In the high-air volume mode, we placed the anemometer at the main outlet and after several moves to collect data, the maximum wind speed measured was 3.4m/s.  Panasonic Air Purifier F-PXP155C: We tested the wind speed at the outlet of Panasonic Air Purifier F-PXP155C. In the low air volume mode, we placed the anemometer at the main air outlet, and after several movements to collect the data, the final measured maximum wind speed was 1.9 m/s.  In the high-air volume mode, we placed the anemometer at the main outlet and collected the data after several movements. The final measured maximum wind speed was 6.38 m/s.  Mori Chen MCW1 Air Purifier: We tested the wind speed at the outlet of this Mori morning MCW1 air purifier.  In the high-air volume mode, we placed the anemometer at the main outlet and after several moves to collect the data, the final measured maximum wind speed was 4.61m/s. This data is among the many air purifiers currently tested. High. Test summary: The wind speed is an important reference for measuring the purification capacity of an air purifier, and also affects the efficiency of the entire purification. Among the five products of this Hengping Review, Philips Air Purifier AC5660, Sharp Air Purifier FP-WH70-W, Panasonic air purifier F-PXP155C has a more prominent wind speed, while Morin Chen MCW1 air purifier and breathless smart air purifier have weaker wind speeds.

The performance is more eye-catching than Sharp Air Purifier FP-WH70-W, which is 9.57m/s higher than other products.
Test Item 3: Noise Test Testing purposes: Noise is an important indicator for judging the quality of air purifiers in the new national standard. After adding noise as a reference item in the Hengping Review, it can be combined with purification efficiency to determine the performance of an air purifier. How to ensure Under the premise of purification efficiency, reduce the machine noise? We continue to read the following horizontal comparison evaluation. Noise standard: New national standard, when CADR ≤ 150m 3/h, machine noise should be ≤55 dB; when 1503/h, machine noise should be less than or equal to 61 decibels; when 300 hours, machine noise should be less than or equal to 66 decibels; when CADR>450m 3/h, machine noise should be less than 70 decibels. Test Methods: The decibel meter is used to sample the ambient noise, and then the low and high gears of the purifier are sampled. The noise floor in the test environment is 30dB.  Philips Air Purifier AC5660: When the Philips Air Purifier AC5660 is turned on at full speed, the decibel meter shows a decibel of 58.9dB. This value is equivalent to the noise we usually talk when talking. It is the ideal decibel state.  After starting the sleep mode, the test score was 30dB, which was surprisingly consistent with the noise in the room! The sound from any air purifier was not detected at all.  Sharp Air Purifier FP-WH70-W: What is the actual effect of Sharp Air Purifier FP-WH70-W on noise? We selected the weak windshield and collected data near the airframe. The data obtained was 30dB. The noise was consistent with the ambient noise and no noise was generated.  After that, we started the stroke mode and the sound was not much increased. It can be seen through the value of 47.8 dB that this noise will not affect the daily life. The family with children at home can rest assured.  Finally, when we turned on the strong wind mode, the sound was significantly increased, the measured data was 60.1 dB, and the number of decibels increased.  Breathless Air Purifier: During the decontamination process, we measured the noise level at about 1 meter and the noise was about 53 decibels. The sound was obvious, but it didn't feel too noisy. It was much quieter than the purifier we evaluated before. This is officially acceptable with the hammer. Noise' under strong purification meets.  Approximate results were also obtained in specialized noise tests, as shown in the figure.  Sleep mode  Strong wind mode Panasonic Air Purifier F-PXP155C: First of all, we put the Panasonic air purifier F-PXP155C to the first gear, and the measured data is 36.7 dB, which is higher than the indoor ambient noise.  Finally, we adjusted the wind power of Panasonic air purifier F-PXP155C to the highest grade. The measured data was 59.1dB, and the noise was significantly improved.  Mori Chen MCW1 Air Purifier: First select 1st gear, collect data at a distance of 1 meter from the fuselage, the obtained data is 45.5 dB, and the indoor environment noise is not much different, and the human ear can hardly distinguish.  Then in the highest 5-speed mode, the sound was significantly increased, and the final measured data was 68.8 dB.  Test summary: As a household appliance, the noise decibel number has always been one of the focuses of consumers. The five air purifiers participating in the horizontal evaluation are basically close to the ambient noise when operating at a low speed, and will not affect the life. During the high speed operation, among the five air purifiers, the Philips Air Purifier AC5660 and the Panasonic Air Purifier F-PXP155C are less than 60 dB, while the other three models are all higher than 60 dB. Among them, the Mori Chen MCW1 air purifier noise Up to 68.8 dB, placed in the room will have an impact.
Test Item 4: Power Consumption Test Testing purposes: The last indicator in the new national standard is energy consumption. Energy consumption is directly related to the daily expenses of users. Generally speaking, the higher the energy consumption, the more expensive the electricity cost. Therefore, the last data of this test is energy consumption. What about the energy consumption of the five air purifiers involved in the horizontal comparison evaluation? Test Methods: The power meter is used to test the power values of the low speed and high speed gears of the purifier respectively. To ensure the accuracy of the data, the air purifier is set to the corresponding gear position and waits for 15 minutes until the power is relatively stable. It takes readings. Philips Air Purifier AC5660: The author used a power tester to test the full wind speed and sleep mode status of Philips Air Purifier AC5660.  First of all, the power running in sleep mode is 12W.  In the full wind speed mode, the measured power is 61.1 W. Sharp Air Purifier FP-WH70-W: We tested the Sharp Air Purifier FP-WH70-W for power consumption. We also used weak wind and strong wind to test. In the weak wind mode, the normal operating power of the host is 5.0W.  In strong wind mode, the normal operating power of the host is 65W.  Breathless Air Purifier: We tested the actual power of the breathless air purifier. We chose the lowest gear and the highest gear. The actual operating power in the lowest gear is 12.89W.  The actual operating power in the highest grade mode is 107.3W.  Panasonic Air Purifier F-PXP155C: We tested the power consumption of the Panasonic air purifier F-PXP155C. We also used low wind speed and high wind speed for testing. In low wind mode, the normal operating power of the host is 6.6W.  In high wind mode, the normal operating power of the host is 71W.  Mori Chen MCW1 Air Purifier: Below we have to carry out the actual running power test. We use the 1st and 5th gears. In the 1st gear mode, we get the actual operating power of 10.3W, and in the 5th gear mode, the power is 43.2W.   Test summary: In terms of power consumption, Mori Chen MCW1 air purifier is the lowest among the five models, while the power consumption of the Philips Air Purifier AC5660 and Sharp Air Purifier FP-WH70-W is among the lowest. The power consumption of the device is the highest, but the overall value, the power consumption in a controllable range, does not cause excessive burden on the daily power.
Evaluation summary: In the eyes of consumers, the purification effect is a measure of the pros and cons of an air purifier. In fact, for air purifiers, the key is not only the purification effect, but also its filter, noise, energy consumption, and wind speed. All of them are very critical. Moreover, after the 80s and 90s, these valued consumers are also one of the indicators that they consider purchasing air purifiers. Today, YOG appliances have selected five air purifiers below RMB 10,000 through different latitudes. , And carried out this horizontal evaluation, to provide users with a better solution to choose air purifiers. Philips Air Purifier AC5660: Throughout 2017, Philips' contribution to the air purification industry was obvious to all. The Philips Air Purifier AC5660, which participated in the horizontal comparison evaluation, performed well overall. The appearance was more pleasing, the size was moderate, and the purification effect was obvious. The speed is also among the top three products participating in the Hengping review. The comprehensive index is better, and the convenience of replacing the composite filter is also improved. Comprehensive recommendation index: ★★★★★ Awarded: Annual Editor's Choice Products Award Sharp Air Purifier FP-WH70-W: Appearance, Sharp Air Purifier FP-WH70-W is definitely a product worth bursting, very stylish sense; performance, purification speed slightly less than other models, but fortunately the purification results are more gratifying. Actual tests of noise, power consumption, and wind speed are also good, but if the user struggles with cleaning speed, the Sharp Air Purifier FP-WH70-W will have a slight drop. Comprehensive recommendation index: ★★★★☆ Awarded: Optimal Color Value Award Breathe smart air purifier: Respiratory smart air purifiers are believed to be well-understood by many consumers, all of which are derived from the superior cleansing power of the 800CADR that was much higher than the industry at that time, and the impact on the market was great! For this, PM2.5 purification The test is also very obvious, whether it is purification speed or purification rate is very good. In the conventional test, strong wind file effect is very good, but the relative power consumption is also slightly higher, this can also be understood from the perspective of energy efficiency. But for A brand newly added to an empty and clean family can have a higher rise. Comprehensive recommendation index: ★★★☆☆ Awarded: User favorite award Panasonic Air Purifier F-PXP155C: Panasonic air purifier F-PXP155C is also a veteran air purifier manufacturer.
