Key Benefits

  • Removes 99.99% of airborne particles.

  • Reduces odours, gases and VOCs.

  • Ideal for large rooms up to 630 sq. feet.

  • Auto-mode adjusts based on air quality.

  • Quiet operation for peaceful environments.

The AmazingAir 3500 Air Purifier delivers reliable, high-performance air purification with a classic design and updated filter system. It uses a powerful 3-stage filtration process to ensure cleaner, healthier air throughout the home.

The first stage includes a cleanable pre-filter that traps larger particles like dust and pet hair. The second stage features a dual-action Carbon Gas Trap/VOC filter, which reduces odours, harmful gases, and volatile organic compounds such as formaldehyde. The final stage uses an independently tested and certified UltraHEPA® filter that removes 99.99% of airborne particles as small as 0.003 microns, including pollen, mould spores, smoke, bacteria, and viruses.

The AmazingAir 3500 cleans the air four times per hour in rooms up to 630 square feet, making it suitable for bedrooms, living areas, kitchens, and other large spaces. Its built-in Air Quality Sensor powers the auto-mode, which adjusts fan speed in real-time based on the detected air quality. Manual control includes a 4-speed fan, dimmer, and timer settings, offering users full control over performance.

A sealed system prevents particles from leaking back into the air, while the change filter alert ensures optimal performance by reminding you when to replace filters. Quiet performance makes it easy to use throughout the day or night without disturbance. The AmazingAir 3500 Air Purifier combines efficiency, smart functionality, and thoughtful design to support a cleaner indoor environment.

Unlike many air purifiers, the AmazingAir 3500 offers scientifically-backed performance with proven results. Third-party laboratory tests by MRIGlobal confirm that it eliminates 99.99% of airborne live SARS-CoV-2. It also traps the same high percentage of bacteria and other viruses, such as H1N1, showcasing its superior filtration capabilities. The UltraHEPA® filter in the AmazingAir 3500 can capture airborne particles as small as 0.003 microns, a size that many standard purifiers cannot handle. These results highlight its ability to effectively remove harmful contaminants, making it a highly effective option for improving air quality.

AmazingAir was founded with a clear mission to improve indoor air quality and promote healthier living. Driven by a commitment to scientific innovation, the brand focuses on creating affordable, high-performance air purifiers. By combining advanced technology with an environmentally conscious approach, the brand ensures that every home breathes cleaner, fresher air. AmazingAir empowers individuals to live their best, healthiest lives with the air they breathe.
