400 Series-Cut-Out

3-Stage Comprehensive Filtration — Including Super HEPA Upgrade Option:

  1. Pre-Filter – Grabs and traps large particles such as hair, lint, dust and dander, and in doing so extends the life of the HEPA and carbon filters. It measures 570 sq. inches and 1 inch deep. Change every 12 months and vacuum clean for better performance.
  2. Carbon Filter – 8 lbs. of activated carbon in a 1” deep, high-quality carbon bed to absorb airborne chemicals, odors, VOC’s and gaseous fumes. The carbon filter will typically need changing every 2 years depending on air quality and usage.
  3. True HEPA Filter — Choose Between Two Levels of HEPA Filtration
    • Standard HEPA: Equipped with a 40 sq. ft. medical-grade True HEPA filter, the G600 is able to trap up to 99.97% of particles down to 0.3 microns. Has a lifespan of approximately 3 years.
    • Super HEPA: H14 Super HEPA filter removes up to 99.99% of airborne particles down to 0.3 microns in diameter and smaller.

The Airpura Difference – Built for Health & The Environment

  • No Off-Gassing: Built without the use of plastics, rubbers, or adhesives associated with emitting toxic gasses or VOC’s. The only exceptions include the presence of some materials required to meet UL, ETL, CE and CSA safety standards.

  • Felt Gaskets: All gaskets are made from felt instead of rubber, which helps seal each component and create highly effective air filtration. Felt gaskets have the ability to further reduce off-gassing as well. Additionally, these units have fully sealed filter, motor, and electrical chambers.

  • Metal Housing: Constructed entirely from solid steel on the outside, the reduction of plastic components in favor of metal housing contributes to the decrease in off-gassing. The all metal housing is also a more environmentally friendly material in general as it’s 93% recyclable.

  • PCB Free: Electrical equipment often includes capacitors that are made from PCBs; polychlorinated biphenyls. PCBs have been associated with a variety of types of cancers. Airpura capacitors are all made with entirely PCB-free materials.

  • Pure Air Flow: Engineered so that the units motor is positioned away from the flow of air. Most air purifiers are designed in a way that as air passes over the motor, new impurities are picked up before exiting the unit. Airpura air purifiers were designed to prevent this.

It verks!!!

The R400 is a great size and it works great in our bedroom. Its simple design was one of the reason why I bought an Airpura instead of another brand. Quality materials, easy to operate. Made in Canada.
