Key Features

The AIRDOCTOR AD3500 is loaded with advanced features to improve air quality in larger rooms. Here’s an overview of its standout features:

UltraHEPA Filtration

The UltraHEPA filter is one of the AD3500’s key features, capturing 100% of particles as small as 0.003 microns—far smaller than the 0.3 microns most standard HEPA filters can capture. This makes it incredibly effective at removing allergens, bacteria, mold spores, and even smoke particles from the air.

Dual-Action Carbon and Gas Trap Filter

In addition to particle filtration, the AD3500 includes a dual-action carbon filter that targets gases, odors, and volatile organic compounds (VOCs). This filter helps eliminate harmful chemicals from the air, such as those from cleaning products, paints, or cooking, making it especially beneficial for households with pets or frequent cooking odors.

Four-Stage Filtration System

The AD3500 features a four-stage filtration system:

Pre-filter: Captures larger particles like dust, hair, and pet fur.

Dual-Action Carbon Filter: Absorbs harmful gases and odors.

UltraHEPA Filter: Removes microscopic pollutants, ensuring cleaner air.

Ionizer (Optional): Enhances particle capture by releasing negative ions that help trap particles.

Room Coverage

Capable of covering areas up to 893 square feet, the AD3500 is ideal for large living rooms, open-plan spaces, or small apartments. It offers up to five air changes per hour in smaller spaces, ensuring continuous air purification.

Auto Mode with Air Quality Sensor

The built-in air quality sensor continuously monitors the air and adjusts the fan speed accordingly. The LED indicator changes color to reflect current air quality, ranging from blue (good) to red (poor), giving you real-time insight into your home’s air.

Quiet Performance

With noise levels between 30 and 50 decibels, the AD3500 is designed for quiet operation. Whether placed in a bedroom, living room, or office, it won’t disrupt your environment with excessive noise.

Energy Efficient

ENERGY STAR certified, the AD3500 is energy-efficient and designed to operate without significantly increasing electricity consumption, even with continuous use.

Filter Life Indicator

The AD3500 includes a filter life indicator, ensuring you know exactly when it’s time to replace the filters for optimal performance.
