Product Information
Full details
The Bosch Air 4000 is an ideal air purification solution for homeowners and apartment dwellers looking to improve indoor air quality in rooms up to 62.5 m². Its primary strength lies in its powerful 3-in-1 filtration system and intelligent auto-adjustment features, which effectively neutralize allergens, dust, and odors with minimal intervention. While it offers robust performance and a sleek aesthetic, users should note that the unit occupies a dedicated floor space of nearly 30 cm squared, making it best suited for rooms where placement can be strategically managed.

Troubleshooting
Unit will not turn on
Ensure the power cable is securely plugged into both the unit and the wall outlet; check if the unit is in the correct room or if the child lock is preventing input.
Airflow seems weak even on high settings
Check the air intake and output grills for obstructions; verify that the internal filter is properly seated and not fully saturated with dust.
Sensor keeps detecting poor air quality

Setup, Compatibility & Care
Setting up the Air 4000 is straightforward: remove all packaging from the included filter, install it into the housing, and connect the unit to a standard wall outlet. For optimal airflow, place the unit at least 30 cm away from walls or furniture.
To ensure peak performance, clean the exterior housing with a dry, soft cloth. The pre-filter layer should be inspected periodically for dust accumulation. When the internal sensors indicate the filter has reached its capacity, replace the entire 3-in-1 unit to maintain effective air filtration. Always utilize the child lock function in households with pets or children to prevent accidental setting changes.
