Product details
The core advantage of the Wall-mounted fresh air machine is that it does not require complex ceiling or pipe installation, is easy and flexible to install, and can efficiently introduce filtered fresh air. It is suitable for families that have completed decoration or small Spaces.
1. Low installation threshold and strong adaptability: No need to damage the original decoration (such as ceiling and wall grooves for pipe laying). Usually, only holes need to be drilled in the wall for fixed installation. It is especially suitable for renting houses, old houses or already decorated residences, avoiding the trouble of secondary decoration.
2. Small space occupation and no impact on layout: The body is hung on the wall (mostly on the high walls of bedrooms and living rooms), does not occupy floor or table space, and has no effect on the placement of indoor furniture or activity areas. It can be easily adapted to small-sized apartments.
3. Rapidly improve local air quality: Precise air supply for individual rooms (such as bedrooms and children's rooms) can quickly filter out outdoor PM2.5, pollen, dust and other pollutants, while expelling indoor CO₂ and odors, enhancing the freshness of the air in the local space and meeting the ventilation needs of the core area.
4. Simple operation and convenient maintenance: Most models are designed simply, equipped with a clear operation panel or mobile APP control, allowing for one-click adjustment of wind speed and timing. The filter screen is easy to replace (mostly in the front or side-opening design), and no professional personnel are required. Users can operate it by themselves.
5. Lower energy consumption and cost: Compared with central fresh air systems that require piping, wall-mounted models have less power and lower daily energy consumption.
Moreover, the purchase cost of a single unit of equipment is much lower than that of central fresh air systems, offering a higher cost performance. It is suitable for users with limited budgets or those who only need local ventilation.
