In winter, there is a high incidence of haze, even in the room with closed doors and windows, PM2.5 pollution can not be blocked. And indoor air pollutants, including formaldehyde, benzene, bacteria and other indoor air pollutants, which are undoubtedly a great threat to children, the elderly or people with weak physique. Therefore, indoor air purifier is one of the effective means to ensure respiratory health. However, there are still some misunderstandings in the use of air purifier:
Air purifier with built-in PM2.5 sensor
Most air purifiers on the market do not have the function of filtering PM2.5, so it is completely invalid to purchase this type of air purifier for use in haze days. At the beginning of purchase, it is necessary to confirm whether PM2.5 and other indoor pollution parameters are within the filtering range, and be familiar with power and purification effect.
At present, many people use air purifiers by feeling, such as vision (seeing a haze outside), smell (smelling a pungent smell), and feel (often dizzy and chest tightness indoors). But is it fog or haze? Is it really caused by indoor air pollution? No one knows, because there is no data to check. Therefore, it is a new trend to install air monitoring equipment indoors first.
Before using the air purifier, the doors and windows should be closed first, because the air purifier is only effective in relatively closed space, otherwise the outdoor air will continuously enter the room, even if the air purifier keeps the maximum power operation, it will not have any effect, and on the contrary, it will quickly consume the life of the filter element.
Generally, the indoor effective purification range of air purifier is 15 ㎡ ~ 20 ㎡, but the range is slightly different according to the machine power produced by each manufacturer. Therefore, when the indoor area is large, we need to consider whether to increase the number of air purifiers.
Closing doors and windows for a long time and using air purifier will reduce oxygen and increase carbon dioxide in the room. If the air monitoring instrument reminds that the carbon dioxide value exceeds the standard, it is recommended to open the window for ventilation for a period of time to avoid the discomfort caused by the high carbon dioxide.
The treatment effect of the air purifier can be seen intuitively through the air monitoring instrument. When the treatment effect is greatly reduced, it may be caused by the saturation of the filter element, and it can be replaced. Of course, the service cycle of general filter element is about one year, but the final replacement should be subject to the actual treatment effect.
Before switching on and off the air purifier, you can check the value of the indoor air monitoring instrument. If the value is in the healthy range, you do not need to turn on it. Especially in the evening, because the noise from the air purifier during the quiet night will affect sleep.
In a word, air purifier is a good way to control air in a small area. It has many advantages such as timely governance, low cost and high flexibility. If it can be used together with indoor air quality monitoring instrument, the effect will be better. If there are monitoring, treatment and real-time control of indoor air quality data, then there is no need to worry about the harm caused by pollution.
Air quality sensor brand luftmy, air quality sensor gds06 uses the principle of optical scattering to obtain the particle concentration, and measures the dust concentration within the detection range through the conversion of optical path and circuit. Air quality sensor gds06 has the characteristics of small volume, high precision, low power consumption and short response time. This air quality sensor can be used in air purifier, lampblack machine, etc. Please consult online for more air quality sensor prices.
