• Stage 1 - Pre-Filter
  The cleanable pre-filter will trap large particles such as lint, dander, hairs, and dust. Replacing the pre-filter on a regular basis is important in order to maintain the integrity and life of the Carbon filter. The pre-filter is 1-inch thick and contains 570 square inches of material. (For black units, a black pre-filter sleeve is also available for aesthetic purposes.)
  Replace the pre-filter every 6-12 months.
  
  
• Stage 2 - 26 Pound Carbon Module
  Carbon is KING when it comes to odor, gas, and chemical removal. It will adsorb airborne chemicals including formaldehyde, acid gasses, and volatile organic compounds (VOCs). The 3-inch, 26-pound carbon bed in the Airpura C-series air purifiers is ample enough to last for 2 years! How does the carbon continue to adsorb chemicals and odors for such a long time? Activated carbon has millions of tiny pores between the carbon atoms. There are so many of these pores that one pound of activated carbon has a surface area of 60 to 150 acres. Adsorption is the process where certain chemicals, gases, VOCs, and odors are attracted to activated carbon and then bond to it. Millions of pores provide an enormous surface area to adsorb chemicals. Two MicroSupress filters surround the 26-pound carbon module to inhibit the growth of bacteria, antigens, and pathogens.
  Replace the carbon ring every 2 years.
  
  
• Stage 3 - HEPA-Barrier Post Filter
  The specially designed HEPA-Barrier post-filters trap any carbon dust or particles from the carbon bed.
  Replace the HEPA-Barrier post filter every 12-18 months.

THE AIRPURA C-SERIES AIR PURIFIERS CAN REMOVE OVER 4,000 AIRBORNE CHEMICALS, INCLUDING THE FOLLOWING;

The Airpura C600 and C700 air purifiers are guaranteed to provide pure air. It's manufactured in a facility that promotes environmental awareness with a low carbon footprint. Airpura builds all of its air purifiers with premium filtration performance while sustaining green considerations throughout the entire manufacturing process. FACT - 93% of the Airpura C-series air purifiers are recyclable.

WHY CHOOSE THE AIRPURA C600 OR C700 AIR PURIFIER? HERE ARE THEIR UNIQUE FEATURES...

• Contact Time - This feature is especially important for airborne chemical abatement. The amount of time that the chemical contaminants are in contact with the 26-pound carbon bed is vital. The variable speed control allows you to set the airflow precisely and achieve the results you need.
• Pressure Seal - This important feature eliminates unfiltered air bypass. It ensures that ALL air passing through the Airpura C600 and C700 units comes in contact with ALL filters, including the HEPA filter. This results in a TRUE particle removal rating of 99.97%. Airpura units feature a unique pressure and reusable gasket that includes NO glues, silicones, or rubber compounds.
• All Metal Housing - Simply stated, metal does not off-gas. Unlike some plastic housings, the Airpura C600 and C700 air purifiers feature a perforated, powder-coated steel housing. This not only offers a softer appearance but allows for 360-degree air intake and distribution. The C-series air purifiers will not emit VOCs or plastic vapors into your environment.
• Backward Curved Motorized Impeller - A smaller yet more powerful motor enhances airflow while keeping noise level to a minimum. Variable speed allows you to choose the ideal level of airflow. The unique position of the motor avoids internal turbulence and does not interfere with airflow.
• Environmentally Conscious Design - Airpura air purifiers do not contain any plastic, rubber, silicone, adhesives, or bonding agents. (other than a minute amount required to meet UL, ETL, CE, and CSA safety requirements) The capacitors are PCB-free and no lead is used in soldering the speed control. Rivet fastening, despite a slightly higher cost and more time, is used instead of spot welding. This prevents additional off-gassing of particles and chemical vapors including greenhouse gases. The ingenious 'sock' filter liner in the carbon bed allows for better airflow throughout the carbon granules while reducing the amount of material used.
