Product Overview
The AIRDOCTOR AD3500 is a freestanding room air purifier that combines particle filtration with carbon-based odor and gas filtration. The unit uses an UltraHEPA filter, a dual-action carbon and gas-trap filter, and a washable or serviceable pre-filter arrangement as part of its multi-stage filtration system. An integrated air-quality sensor allows the purifier to adjust fan operation automatically when Auto Mode is selected.
The AD3500 is designed for medium and larger indoor rooms and includes multiple fan speeds, filter-change notification, touch controls, and a sealed filtration pathway. Published specifications identify a low operating-noise level of approximately 34 decibels under applicable conditions. Coverage figures vary depending on the number of desired air changes per hour, so room-area claims should always be interpreted together with circulation frequency. This reference applies specifically to model AD3500 and not replacement filters or other AirDoctor purifier sizes.
