After the epidemic, the fresh air system once again refreshed people's understanding. The fresh air system can not only provide 24 hours of uninterrupted ventilation and ventilation, its filtering function, but also reduce the entry of outdoor bacteria and avoid cross infection. After this incident, I believe that the fresh air system will gradually become a standard package for primary and secondary schools, real estate, and public places.
As our lives and work are gradually on the right track, many people continue to work on renovations that were not possible in the spring. Don't be entangled, the home fresh air system will be arranged sooner or later, and installed as soon as possible to ensure the health of the indoor home. The following three aspects explain how the fresh air system guarantees clean and healthy indoor air:
1 / Farewell to spring sleepy, you need a little fresh wind
Frequently open doors and windows in spring to maintain the circulation of fresh air in the room to increase oxygen content and reduce harmful gases such as carbon dioxide, which can alleviate the occurrence of "spring sleepiness". However, due to the haze, outdoor dust, and air pollution, indoors often cannot guarantee window ventilation. The fresh air system meets this demand. It can ensure effective fresh air and increase indoor oxygen content without opening the window.
The central fresh air system can provide independent fresh air purification solutions for individual rooms by rationally designing pipes and air outlets. By continuously introducing outdoor fresh air, it can solve the problems of air turbidity and increased CO concentration caused by indoor ventilation.
Similarly, the fresh air system can effectively improve the occurrence of "air conditioning disease" when the air conditioning is turned on in summer.
2 / The fresh air system effectively isolates external pollution
The fresh air system filters the outdoor air heavily, purifies the pollutants in the air, and then introduces them into the room, which can effectively isolate external pollution. The fresh air system will maintain a certain pressure difference between the indoor and the outdoor, and isolate the outdoor air from the doors and windows, and can only enter through the fresh air inlet, thereby isolating the external pollution. In cities with harsh environments and outdoor haze, such as Beijing, Henan, Hebei, Shandong, and Northeast, where the air pollution index is frequently reported, it is recommended to install a fresh air system.
3 / N95 grade HEPA filter effectively filters bacteria and viruses
During the epidemic, we all know that N95 masks can effectively isolate virus transmission. N95 masks have a high filtration efficiency, and N95 masks have a filtration efficiency of not less than 95% for 0.3 micron particles. The HEPA filter widely used by the fresh air system is equivalent to wearing a large "N95 mask" for the home space, effectively filtering and purifying bacteria and viruses. The HEPA filter is a high-efficiency filter, which requires a filtration efficiency of at least 99.97% for PM0.3 (particulate matter with a diameter of about 0.3 microns).
Viruses are parasitic in a cell, and only microorganisms such as bacteria can provide parasitic conditions for viruses in the air, and all airborne microorganisms are attached to aerosols in the air, such as droplets and particles. The diameter of the droplets is more than 10 microns, and the diameter of our best-known PM2.5 is also about 2.5 microns, so whether it is a carrier that intercepts viruses, or particles such as catkins, pollen, dust, etc. in the air, the HEPA filter has Interception effect.
Choose a fresh air system to give your home "N95" level of protection. The indoor fresh air system specializes in creating clean home spaces.
