The wall-mounted fresh air system is an independent fresh air device installed on the wall. In recent years, it has attracted attention for its convenience and flexibility.

‌Core advantages‌

‌Pipeless design, easy installation‌

No need for complex pipe laying, only need to drill holes in the outer wall (hole diameter is usually 10-15cm), suitable for renovated homes. Short installation period (2-4 hours), and little damage to the wall.

Example: When renovating an old house, there is no need to remove the ceiling or floor, reducing the decoration cost.

‌Independent control, flexible use‌

Supports single-room installation, can be turned on and off as needed (such as only used in the bedroom at night), avoiding the energy consumption of fresh air in the whole house. 

Some models support mobile phone APP remote control, suitable for smart home scenarios.

‌Controllable maintenance cost‌

The filter is easy to replace (users can operate it by themselves), the primary filter is replaced about 3-6 months, and the high-efficiency HEPA filter is replaced every 6-12 months, and the annual maintenance 

cost is about 300-800 yuan (depending on the model).

‌Outstanding silent advantage‌

The noise can be controlled at 25-35dB (equivalent to whispering) when running at low speed, and it does not affect sleep when used at night. Some high-end models use brushless DC motors to further reduce noise.

‌Price-performance ratio for beginners‌

The unit price range is 1,500-5,000 yuan, which is much lower than the central fresh air system (more than 20,000 yuan). Suitable for users with limited budgets or small apartments (such as single apartments, children's rooms)
