[PConline evaluation] Since the fall and winter season in Beijing and other places, haze weather has repeatedly hit, and most families will close doors and windows. We live indoors most of the time. In this case, the indoor temperature is high, and the lack of air circulation makes it particularly prone to bacterial growth. The cold germs spread quickly indoors and the elderly and children are more likely to be infected. At the same time, indoor PM2.5 can not be ignored, if the room is not ventilated for a long time, coupled with a relatively high level of Habitat activities, pollutants can easily accumulate.
How can we do it? Is indoor air health so easy to ignore?

â— Filter system dismantling
The TCL TKJ800F-A1 air purifier is equipped with an Allle-Sauber filter system. It is powered by a powerful double-guided wind turbine technology that drives dual filter cartridges for powerful filtration for filtration, interception, and full adsorption. The double-effect filter element has multiple purification protections through the preliminary antibacterial filter, high-efficiency HEPA filter, normal-temperature catalytic activated carbon, negative ion purification, and UV lamp sterilization.
Simple and quick installation and removal of filter
Antibacterial filter
Open the first layer of the air purifier filter as a pre-filter. The pre-filter can effectively capture large particles such as dust and hair, and strongly remove large particles of dust in the air.
The TCL TKJ800F-A1 air purifier also uses a hybrid filter. The HEPA purification technology used in the TCL TKJ800F-A1 uses low-winding and high-efficiency meltblown static electret materials, and efficiently filters air to collect PM2.5, dust, pollen, and soot. Animal dander and other particulate matter.
Composite filter HEPA filter combined with normal temperature catalytic activated carbon filter
Room temperature catalytic carbon
At the same time, in the aspect of de-formaldehyde, it is equipped with room-temperature catalytically modified activated carbon technology and adopts self-developed normal-temperature catalytically modified activated carbon to efficiently remove harmful pollutants such as formaldehyde, benzene, toluene, and xylene.
Negative ion purification
The Alle-Sauber filter system quickly purifies the air while allowing negative ions to fill the room quickly. The negatively charged particles in the air increase the oxygen content in the blood, which is beneficial to blood oxygen delivery, absorption and utilization. It has the functions of promoting human metabolism, improving human immunity, increasing human muscle energy, and regulating the balance of body functions.
UV lamp sterilization
The TCL TKJ800F-A1 air purifier not only purifies indoor airborne particulate matter and harmful contaminants, but also kills E. coli, Staphylococcus aureus, bacteria, and molds through UV lamps. It lengthens the irradiation range and matches the length of the filter width to achieve more efficient killing.
â— purification capacity test
The indoor home purification effect of an ordinary home is the key to determining the quality of the air purifier. This time we selected a 25-square-meter simulated home environment for testing. After lighting up the cigarettes in a closed room to make it fully burned, the second-hand smoke is filled throughout the room. Using the tester to test the PM2.5 index in the air, PM2.5 was measured every 10 minutes and the purifying effect of this air purifier was measured at different times.
After the cigarette burned, the odor diffused into the room. The indoor air pollution index was tested with an air quality tester. It was found that the 0.5um particle concentration value was as high as 200503, which was a very heavy pollution level.
Turn on the air purifier for testing
Turn on the air purifier, adjust the wind speed to the maximum gear mode, and enter the simulated home environment every 10 minutes for testing. Using the detector to measure the concentration of PM2.5, it was found that the TCL TKJ800F-A1 air purifier has an amazing purification effect.
Tested in a 25 m2 sealed environment
Summary: From the test of purification capacity, we can see that the high efficiency of TCL TKJ800F-A1 air purifier is amazing. It only takes less than 20 minutes to purify indoor polluted places. The double powerful filter and the All-Sauber filter system make the purification effect highly efficient and provide a guarantee for the family's respiratory health.
â— Air volume and noise test
Air volume test
Next, we will test the wind speed and use the five wind speeds respectively. The wind speed will determine the CADR important factors of the purifier. It has become one of the indicators of purification ability. TCL TKJ800F-A1 air purifier adopts Shinano DC motor from Japan Nissan and RadiCal backward centrifugal fan, which can output a constant amount of air volume and rotate 2650 times per minute. , Output 1180m3 per hour.

Second gear speed 0.8m/s Third gear speed 1.15m/s 
Four stalls wind speed 2.18m/s Five stalls wind speed 4.82m/s Noise test
Many consumers want their products to be as silent as possible, especially when they need to be muted at night. Both can filter without affecting the normal night's sleep. This time we also selected five gears to test the noise of the TCL TKJ800F-A1 in an environment of about 36dB.
TCL TKJ800F-A1 noise test
Mute gear noise: 45.1dB (A) One gear noise: 45.6dB (A) 
Second gear noise: 46.0dB (A) Third gear noise: 46.8dB (A) 
Fourth gear noise: 50.03dB (A) Five gear noise: 57.2dB (A) Summary: The TCL TKJ800F-A1 air purifier uses a dual air inlet double strainer system that incorporates aerodynamics to quickly purify the indoor air flow. In the noise test, it clearly wins the opponent. The noise of the strong wind speed will not be harsh. When the mute gear is turned on, Xiao Bian completely cannot hear the noise from the fan.
â— Power test and summary
The air purifier must be used for a long time, so the power used is particularly concerned. This time we have selected five stalls for testing. Test them separately to see how much power they are working on.
TCL TKJ800F-A1 Power Consumption Test
Mute gear instantaneous power consumption: 5.15W instantaneous power consumption in a gear: 6.7W
Instantaneous power consumption in second gear: 8.52 W Three-position instantaneous power consumption: 12.53 W 
Four-speed instantaneous power consumption: 27.13W Five-speed instantaneous power consumption: 70.16W Summary: The TCL TKJ800F-A1 air purifier A was found to be quite satisfactory in six modes from instantaneous power tests. The power in the silent mode was only 5.15W. The power at strong wind speed is slightly larger, but this mode can achieve rapid purification. When the purification is completed, the power of the automatic gear or mute gear can be reduced.
Full-text summary: TCL This TKJ800F-A1 air purifier has a CADR value of up to 800m3/h and a formaldehyde CADR of 450m3/h. Not only does the CCM representing the life of the filter reach the highest F4.P4 level, it far exceeds the values ​​specified by the new national standards for air purifiers. Through our real-world testing, we have learned that not only is the purification performance superior, its Alle-Sauber filter system brings about the effect of fast flowing air. As a high-end model, although the price is slightly more expensive, but it is absolutely the face of harsh haze.
From the appearance, the "jumpers" of the board cards in the computer are small metal sticks (jumper posts) embedded on the motherboard, sound card, hard disk and other devices, and small clips (jumper clips) that are set on these metal sticks. The function of the jumper is to adjust the on-off relationship of different electrical signals on the device, and to adjust the working status of the device, such as determining the mainboard voltage, the master-slave relationship of the driver, and so on. When the jumper clip is put on two jumper posts at the same time, it means that the two jumper posts are connected. If only one or no jumper posts are put on, it means it is disconnected. It is very important to adjust the jumper. If it is jumped incorrectly, it may crash in some cases or even burn the entire device. Therefore, you must read the manual carefully when adjusting the jumper, and check the name of the jumper, the number of the jumper and the on-off relationship.
The jumpers on the motherboard generally include CPU setting jumpers, CMOS clear jumpers, and BIOS write prohibition jumpers. Among them, the CPU setting jumper is the most complicated. If the motherboard is relatively old, you must set the core voltage, FSB and frequency multiplier jumpers on the motherboard. According to the motherboard manual and CPU frequency, set the above corresponding jumpers. Normally, there is a set of jumpers corresponding to the CPU voltage on the motherboard, and each jumper corresponds to a voltage value. Find the appropriate voltage value, plug in a keycap to short it, and select this voltage value. In the same way, find the FSB jumper and multiplier jumper, and set the appropriate FSB and multiplier respectively. Note that only one jumper can be short-circuited in each group of jumpers.
The jumper here refers to the copper connecting wire, which is made of a standard jumper cable and connecting hardware. The jumper cable has copper cores ranging from two cores to eight cores. The connecting hardware is two 6-position or 8-position modular plugs. , Or they have one or more bare wire ends. Some jumpers have a modular plug at one end and an 8-position module slot at the other end, or are equipped with 100P wiring plugs, MICs, or module slots. Jumpers are used on the distribution frame to transfer various links, and can be used as a distribution frame or equipment connection cable. Both ends of the modular jumper are RJ45 connectors, adopt TIA/EIA-568A pin structure, and have a flexible plug-in design to prevent loosening and jamming. The length of the jumper is 1 foot (0.305 meters) to 500 feet (15.25 meters), the most commonly used are 3 feet, 5 feet, 7 feet and 10 feet. Modular jumpers are used in the work area and can also be used as jumpers in the wiring closet. In the small office network or home network DIY installation, the dual-computer interconnection jumper is often mentioned. This kind of jumper is not a standard jumper used in integrated wiring, but a special hardware device connection line. It is used when two PC computers are directly connected by twisted pair, or when two HUBs are to be connected through RJ45 ports. , You need crossover (commonly known as cross-connect wire, jumper). It follows a special connection sequence.
