Description

Aranet4 HOME – 8-Day Trial Offer

Is the air in your space really fresh — or does it just seem that way?

Aranet4 HOME helps you measure real indoor air conditions, including:

• CO₂ level

• Temperature

• Relative humidity

• Atmospheric pressure

The device alerts you when air quality declines, allowing you to decide whether ventilation or an improved air circulation solution is needed — based on real measurements.

Aranet4 uses an NDIR CO₂ sensor, features an e-ink display, and works together with a mobile app.

This offer is designed for those who want to evaluate their indoor environment with minimal risk and understand:

• whether CO₂ levels are elevated at home or in the office

• whether more frequent ventilation is needed

• whether a ventilation or heat-recovery system may be necessary
