We know that with the development of modern society, environmental pollution problems are also increasing. In particular, air quality problems, such as automobile exhaust emissions, exhaust gas and smoke emissions from many metal chemical production and manufacturing sites, have seriously affected the air environment quality. Therefore, the demand for air purifiers has also increased. However, many times everyone will compare the fresh air blower and the air purifier together. In fact, the two functions are similar in themselves, and both are auxiliary equipment that can purify the air to a certain extent. However, this is only broadly speaking. In a narrow sense, there are still essential differences between the two:
The fresh air system means to filter the fresh outdoor air and send it indoors, and at the same time exhaust the dirty indoor air to the outdoors, so that a confined space can realize scientific air convection, which is equivalent to adding a breathing system to the indoor environment. The most important thing is that the fresh air system can continue to work 24 hours a day, regardless of indoor formaldehyde, benzene, toluene, xylene, radon, can all be discharged outdoors.
The air purifier, as its name implies, filters indoor pollutants (smoke, particulate matter, dust, etc.) and purifies indoor air. Purification here mainly requires the use of a filter to filter impurities and particles in the air. In the event of severe haze, the filter needs to be cleaned in time.
In general, the biggest difference between the two is the use of the principle of outer circulation and inner circulation. The fresh air blower has a ventilation function and can supplement fresh air, but it does not necessarily have a purification function, and the purifier must have a purification function. Therefore, if conditions permit, the air purification effect will be better when the two are used together.
