Secondhand smoke is the most common in our daily lives, is also the main indoor pollutants, according to the scientific research of second-hand smoke with tar and ammonia, nicotine, particulate matter, such as PM2.5, polonium - 210 more than 4000 kinds of harmful chemicals and dozens of carcinogens, but want to avoid secondhand smoke pollution indoor, in addition to less smoke cigarettes, is also a necessary preparation of an air purifier for indoor.How can air purifiers use PM2.5 sensors to remove indoor second-hand smoke?
Air purifier is also called the machine, the air cleaner, fresh air purifier, refers to the adsorption and decomposition or transformation of various air pollutants (generally include PM2.5, dust, pollen, peculiar smell, formaldehyde, decoration pollution, such as bacteria, allergens, etc.), effectively increase the air cleanliness of home appliance products, mainly divided into residential, commercial, industrial, building.Air purifier is mainly composed of motor, fan, air filter screen system, its working principle is: the machine inside the motor and fan to make indoor air circulation flow, the air pollution through the air in the machine filter will all sorts of contaminant removal or adsorption, after the air ionization, produce a large number of negative ions, is the breeze fan out, form a negative ion airflow, achieve the goal of clean, purify air.
For all kinds of pollutants in indoor air, including second-hand smoke choose composite air filter is more effective, is to use multiple filters and a variety of cleaner technologies, including pre - filter, HEPA filter, activated carbon filter and light catalytic purification technology, ultraviolet radiation sterilization technology, negative ion purification technology, etc., in the role of multiple filter and a variety of purification technology maybe some consumers for air purification function fully, and started to buy air purifier because everyone is focused on PM2.5, in fact, in addition to being able to remove fine particulate matter, you can also remove formaldehyde is decorated in the home, and a nuisance to second-hand smoke.
When buying an air purifier, users may not know how to choose from a wide variety of products. In fact, as long as you remember two indicators, you can easily solve the problem. One is the removal rate of PM2.5, which should be marked by the testing center of the authoritative department.Second, a good air purifier, not only should have a high efficiency filter net this kind of passive purification mode, but also should have active purification characteristics.
Now PM2.5 sensor has been the standard components in air purifier, LUFTMY recommended LD13C laser PM2.5 sensor module, its high sensitivity, high precision, can detect dust particles 0.1~10 m particle size.High consistency, stable module performance, installed in the air purifier and other environmental monitoring equipment can quickly monitor dust concentration.
