As a place for children to learn and play, kindergartens must provide them with a healthy and safe indoor environment. The installation of fresh air system can effectively deal with indoor pollution. Try to list a few indoor pollution problems below.

If there is too much noise outside the kindergarten, the teacher will often close the doors and Windows to block out the noise so that the children can learn better. However, in the limited space of the classroom, dozens of children and teachers will breathe a large amount of carbon dioxide, leading to a rise in the concentration of carbon dioxide in the classroom in a short time. The most obvious hypoxic environment is to make teachers and students dizzy. For children, this not only reduces their learning efficiency, but may also affect their health.

PM2.5 is not a matter, but a general term for all particles smaller than 2.5 microns in diameter. When these substances are suspended in the air, they are easily inhaled and cause lung damage. If these particles contain toxic substances, the harm to human health will increase. Children in the kindergarten are still developing and their resistance is relatively weak. If too much PM2.5 is inhaled in the air for a long time, it can cause many diseases.

Many kindergartens pay more attention to environmental protection. The desks, wall finishes, toys and other items selected meet environmental requirements. But can indoor air pollution be avoided? The answer is no. While formaldehyde emissions in classrooms should theoretically be kept strictly within safe limits, dozens of desks and chairs are clustered in a small classroom. Besides the pollution that metope coating releases, it is very difficult to assure its content won't exceed safe limits.

Children have less resistance than adults. Many infectious diseases can cause whole populations to spread to each other. If there is no good ventilation environment, it is easy to cause the spread of diseases in the kindergarten.

The fresh air system can continuously deliver fresh air to each room through a special treatment of ultra-silent fans to ensure the oxygen supply in each room, dilute toxic substances in the room and consume very little energy. Depatha Fresh air system is designed to create a safe, healthy and comfortable living environment for you.
