PuroAir 400 HEPA Air Purifier: A Comprehensive Review
The PuroAir 400 HEPA Air Purifier aims to provide clean air for large rooms, boasting coverage of up to 2,145 square feet. With its focus on removing dust, pollen, smoke, and VOCs, it is well-suited for homes and offices.

The built-in particle sensor adjusts the fan speed based on air quality, allowing for hands-free operation and energy efficiency.
The unit also includes a timer, fan speed control, sleep mode, filter replacement indicator, and child lock. These features enhance user experience and safety.
