first Impressions with the AirDoctor AD3500
I've been using the AirDoctor AD3500 air purifier in my living room for a few months now, and the difference in air quality is noticeable. The UltraHEPA filter captures particles 100x smaller than standard HEPA filters, making it incredibly effective at removing allergens, pet dander, and even volatile organic chemicals. With its 2x/hour coverage for up to 1,260 sq. ft., it ensures my whole living space is purified. The air quality sensor and auto mode are a huge plus, as they adjust filtration levels based on real-time conditions, and the whisper-jet fans run much quieter than other purifiers I've tried.
The three-stage filtration system, including the dual-action Carbon VOC filter, provides comprehensive protection, and the four fan speeds allow me to customize noise levels or purification intensity. While the filter replacements are specific to AirDoctor filters, they're reasonably priced and maintain the purifier's high performance.
Here’s a summary of key features, pros, and cons:

Filtration | UltraHEPA + Carbon VOC |
Coverage | 1,260 sq. ft. (2x/hour) |
