The difference between air purifier and fresh air system

Difference between fresh air system and air purifier

1. The installation of fresh air system is complicated, so it is necessary to hoist equipment, lay pipes, introduce fresh air from the equipment into each room, and arrange tuyeres at the end of the pipes. The purifier can work directly when plugged in.

2.

The design of fresh air system refers to the national standard, and the air exchange rate per hour is about 1-2 times, which belongs to the gentle air exchange mode of 0 1, and the air exchange rate is determined according to the position of the tuyere. The purifier has large air volume and high purification efficiency.

3.

The fresh air system is to introduce outdoor fresh air into the room and discharge indoor dirty air; Only the large particles in the air can be preliminarily filtered, and the purifier can completely remove harmful gases such as inhalable particles, formaldehyde, benzene, TVOC and bacteria. In the indoor air, so as to achieve complete circular purification.

4. Due to the performance limitation (wind pressure) of fresh air system, the selection of filter element is monotonous, and the thickness of filter element will lead to small air volume. There are various filter elements of the purifier, which can be equipped for different harmful substances.

5. The fresh air system can't handle indoor air as well as the air purifier, so it can't replace the purifier, but it is just a supplement to the purifier.

6.

The air has 4 degrees, temperature, humidity, freshness and cleanliness. Different needs have different solutions, and the temperature is solved by air conditioning; Humidity is solved by humidifier; Fresh air system solves freshness; The easy-to-clean air purification system solves the cleaning problem.
