Before discussing this issue, we must first make clear that the fresh air system and the air purifier cannot replace each other. The two are complementary relationships. If there are conditions, the proposal can be purchased. If the cost is considered, it can be based on the actual situation. Choose one of them.
The main problem solved by the fresh air system is the replacement of indoor and outdoor air. Without the opening of the window, fresh air enters the house continuously, and at the same time, the indoor carbon dioxide concentration can be reduced, and other indoor air pollutants (formaldehyde, benzene, second-hand smoke) , bacteria, virus, PM2.5, PM0.3) discharged outside.
The function of the air purifier is to form a circulation of air in the indoor space, through which the pollutants (formaldehyde, benzene, second-hand smoke, bacteria, viruses, PM2.5, PM0.3) in the air are adsorbed or decomposed. To achieve the purpose of improving indoor air quality. The disadvantage is that it can not reduce the concentration of carbon dioxide.
The fresh air system, also known as building ventilation, is actually a rigid demand, but most people don't have this awareness now. Once the indoor carbon dioxide concentration is too high, people will easily become dizzy and unable to fight the spirit. Will affect the quality of sleep. At present, like the shopping malls, hospitals, subways, fresh air systems must be installed, there are requirements in the design specifications.
The air purifier was once a hot little appliance, but due to too many fakes on the market, consumers have doubts about the effectiveness of the air purifier, and even some consumers have begun to negate the air purifier. Actually, it is not on the market. High-end air purifiers can already achieve the overall improvement of indoor air quality. Therefore, if you decide to purchase an air purifier, you should try to choose a product that is reliable.
In summary, it is necessary to improve the air quality, and the choice of ways to improve, but also according to their actual situation to decide, once again reminded that the fresh air system and air purifier is a complementary relationship, can not replace each other!
