[PConline Fun Talk] Last week's “Smoke and Fog into Beijing†was once again a “network red†in the circle of friends, and the lively haze of friends in the circle of friends was considered “live with live broadcastingâ€. Whenever this time the South Xiaobian I no longer envy the snow in the north, Xiaobian has taken the initiative to give a few masks to the small partner far away in the Royal Park, and attached a line of words: brothers, treasure! Xiao Bian firmly believes that the partner who received the courier is definitely beef ing.
Because the weather in Beijing has often been such a

More blue heaven, the amount of ... or return to the topic it: Perhaps the difference between the north and the south is large, or may be boring, home appliances group sea "out of the force of a tiger" in a "God Club" seeking A folk secret recipe to remove indoor haze, the other party also boasted: If you don’t work, you will return money. Hai Ge wants people to shoot their chests. Why don't they give flowers to Kelvin?
Kelvin took a look at the party and gave it to me meaningfully, either to try it or not. In this way, the new issue of "Inquisitive Horizons" began with the confirmation of a private secret recipe.
Indoor defrost folk secret:
1, floor fans kept blowing
2, with a hood to pump
3, bottle holes to sprinkle water
For comparison, we also specifically moved the air purifier to do the reference, Kelvin said that under normal circumstances, the general air purifiers that performed within 30 minutes could put our evaluation room in a small dark room (about 25 square meters, burning The three cigarettes were purified to a healthy level (the instrument pointer was pointing to the green area), so our test time was set at 30 minutes and the room was in a healthy level (green area) before the cigarette was smoked.
Ignite three cigarettes in a room of about 25 square meters. After the cigarette burns out and fills the room, record the initial value of 0.5 um particle concentration value (tested with 0.5 um particle concentration value as the comparison object) and take it every 10 minutes after the test starts. One sample data to see the purification of indoor air within 30 minutes.
We first randomly selected the test results of an air purifier in the evaluation room as the reference for the three types of fog removal.
Before purification, the indoor 0.5um particle concentration value is as high as 241764, which is extremely heavy pollution level.
30 minutes air purification situation as shown below
After half an hour, the 0.5um particle concentration was 16175, which was a healthy level.
Test 1: The fan keeps blowingIn order to carry out the experiment smoothly, the sea has contributed its own pockets to repair the broken fan.
After finishing the preparation work, Xiaobian burned three cigarettes in a similar manner.
After the turbid substances of cigarettes are fully fused with indoor air, the 0.5 um particle concentration value is as high as 160897, which is a level of heavy pollution (air level is red area).
Turn on the fan for 10 minutes, record the value and repeat 3 times. (Fan OS: I blow it)
After 30 minutes, the 0.5um particle concentration was 100317, and the air quality was still relatively poor (air level was red).
Test summary: Complete defeat! According to Kelvin's explanation, with the floor fan blowing, the fine particles and dust in the air can settle naturally in a short time, but the essence of the fan blowing is to spread the fine particles, smoke, etc. around the indoor air (it can be understood as “stirring†the air). There is no carrier to adsorb particles in the air, and it is impossible to purify the air.
In fact, it is also expected to be friends, but the fan + filter combination is still effective 噢, interested friends can see: "Fear of Xiao Bian! 45 DIY air purifier is actually good"
The interior ignites three cigarettes. After the indoor air is contaminated with the contaminants, the 0.5 um particle concentration before testing the hood is 392926, which is a severe pollution level.
Start the hood, turn on the maximum amount of air, and turn on the lights (that is, you want to waste electricity).
Record the 0.5um particle concentration value every 10 minutes.
After 30 minutes, the 0.5um particle concentration value was 23919, and the air quality tester showed a border between green and yellow, and it barely returned to the normal range.
Test summary: Kelvin said that it is not surprising that smoke hoods can get rid of indoor air pollutants. After all, suction power is relatively strong. However, it should be noted that the hood can not only take indoor pollutants out of the room. If the start-up time is too long, it will also suck the outside air into the room. If the outdoor air is polluted (such as the fog and haze outside the Royal Park), it will once again "pollution" the indoor air and it will not achieve the purpose of purification.
Test 3: "Black Tech" Shower SprinklerThe amount of homemade sprinkler bottles
Xiao Bian is poor, he has been/(ã„’oã„’)/~~
After the three cigarettes were burned out and the indoor air was fused, the concentration of 0.5 um particles before spraying was tested to be 211,780, or heavy pollution (smoke was not burnt!!!)
With a homemade shower, sprinkle water into the indoor air. Spray water at a high altitude. After the interior is evenly sprinkled, stand for 10 minutes and test the 0.5-μm particle concentration.
Good white purpose small series
Repeat 3 times to get the following table↓
After 30 minutes, the 0.5 um particle concentration was 51828. The air quality tester showed a yellow area and was moderately polluted.
The air was not purified, but the house was completely wet.
Test summary: The use of sprinkled water to change the small particles, but the effect is not obvious, in fact, even without water, airborne particles will naturally settle. Purifying the air by means of watering, the principle is similar to the air after the rain will be clear, but if you assume that the home is raining every day, do you dare to go home?
“Not saying that it is impossible to return money! The sea, we want that God stick to return money.†When I saw the test result, I took the sea and ran to the theory. Who knows that the sea is full of rhetoric, that is, refused to go . Under various threatening inducements, the sea finally embarrassed to say:
The prescription is fifty cents.
The original picture contrasts, come, hurt each other
This experiment only used some rumors in addition to indoor haze and earthwork for normal testing. It was not rigorous. If there is any similarity, it is purely accidental. If the air in the home is really bad, or air purifiers, do not believe it (this time there should be an advertising barrage of the keyboard man). By the way, this original speech came from the air purifier Xiaobian Kelvin.
"Curious Vision" is our newly launched section. It mainly aims to answer some questions about household appliances and smart hardware in daily life through some interesting experiments or tests, and will try to verify some interesting rumors. Everything is only to satisfy you, me, our curiosity.
