Product Overview
The AirDoctor AD3500 is a portable room air purifier designed to circulate indoor air through a multi-stage filtration system. It is intended for residential spaces and other indoor environments where airborne particles, odors, and certain gaseous contaminants are a concern. The unit combines particulate filtration with activated-carbon filtration and continuously moves room air through replaceable filters.
The AD3500 includes an air-quality sensor that can automatically adjust fan operation in response to detected conditions. Multiple fan speeds allow airflow and operating noise to be adjusted for different rooms and situations. Its filtration system includes a pre-filter for larger debris, an activated-carbon component for odors and volatile compounds, and AirDoctor’s UltraHEPA filtration stage for fine airborne particles. Because filtration performance depends on room size, airflow, filter condition, placement, and operating speed, the purifier should be positioned with adequate clearance around its air intake and outlet. Filters require periodic inspection and replacement according to usage and environmental conditions.
