The haze harassed the air purifier to become the 'life-saving straw' in the eyes of many people. However, the use of such products exposed many shortcomings. Because the windows and doors must be closed tightly during use, it means that indoor and outdoor air can not circulate, and the concentration of carbon dioxide Rapid rise also threaten the user's respiratory health.
There is also quite depressing, whether it is million yuan of high-end products or thousand yuan of civilian products, are unable to get rid of this problem, a short time air purifier can really purify the indoor air, but you want It is not enough to rely solely on purifiers to continuously ensure that indoor pollutant concentrations are within the WHO standard.
Not long ago, I have also done the test for the wall-mounted fan and million purification level Purifier comparison, and the results are a bit surprised. Interested friends can click on the link below to read the original:

Discover a new wall-mounted fan VS air purifier
In the experiment, we chose a room of about 20 square meters for comparison test, monitoring and recording the PM2.5 and carbon dioxide concentration at three different indoor locations in real time. Purification and ventilation capabilities have been re-understanding.
Air purifier PM2.5 window in operation concentration
Air purifier operation indoor point PM2.5 concentration
Air purifier PM2.5 concentration near the fuselage during operation
The same operating environment for 30 minutes, the use of purifier test data show that the air near the fuselage will be 'preferential' purification, and away from the air purifier indoor PM2.5 concentrations decreased slightly slower;
Indoor air purifier carbon dioxide concentration in operation
At the same time, indoor carbon dioxide concentration test paper 1660ppm, higher than the national standard set the maximum limit for a long time in this environment is sufficient to threaten our respiratory health.
After the new fan is turned on, the test results are sufficient to illustrate the problem.The indoor PM2.5 concentration test values at three different points are below 10μg / m3,
Open the new fan PM2.5 rear window concentration
PM2.5 concentration near the fuselage after turning on the new fan
Turn on the new fan away from the new fan PM2.5 concentration
The indoor carbon dioxide concentration is reduced to 753ppm, ventilation effect is quite obvious.
Indoor carbon dioxide concentration
This test fully explains the wall-mounted fan compared to two major advantages of the traditional purifier:
▶ Purification effect will not appear partial purification phenomenon
In the process of using the traditional purifier, there will always be a preferential purification of the air around the airframe phenomenon, and once the purifier air volume is insufficient to promote the entire indoor air circulation, there will be partial purification, can not guarantee the continuous purification of the whole house.
The new fan does not exist in the use of this problem, unlike the air purifier, the new fan by maintaining the dynamic balance of indoor air pressure to achieve purification effect, the dirty air is discharged outdoors, while preventing dirty air through the doors and windows gap into the room Its working principle determines the comprehensive and uniform purification effect, and does not appear the phenomenon of partial purification.
▶ ventilation effect significantly effective control of carbon dioxide concentration
Compared with the air purifier, the most important advantage of the new air blower is of course the ventilation function. Through continuous air exchange, the new air blower can always keep the indoor carbon dioxide concentration at a low level during the working process, so that the indoor air reaches the true meaning Clean, which is hard to get by top air cleaners.
The different working principle of the new fan has a great advantage over the purifier, but this does not mean that we can easily choose a product to achieve this effect.At present, the domestic wall-mounted fresh air market is still in its infancy, quite a mixed market There are not many rules at all, whether it is purification or product services, more is the need to conscious manufacturers.
As a consumer, we also need to polish their eyes in the product selection, choose a really easy to use fresh air products. If you have this intention to purchase, please continue to focus on the Zhongguancun Online Home Appliances Channel related evaluation.
