The R600 is the best all around HEPA air purifier on the market in our opinion. It removes odors and chemicals due to 18 lbs of carbon and also does a great job of removing airborne dust due to a 560 CFM motor and true HEPA filter with 40 sq. ft of medical grade HEPA material. You also get the benefits of a MCS air purifier due to a host of next generation features such as: 1) Unobstructed air flow. Air is allowed to move freely through the filters without changing directions which created turbulence and limits true CFM ability. Result: Improved CFM. Noise reduction. 2) Great unit for MSC sufferers. A one piece motor and fan assembly .eliminates the vibration associated with traditionally designed fans that are attached to the motor shaft with screws. More importantly, the fan-motor is outside of the air flow, unlike other air cleaners, which prevents off-gassing. The Airpura's special Swiss made motor is smaller and quieter than any other motor on the market as well. It features a variable speed fan allows you to choose the perfect speed / noise level. Separate electrical part chambers also prevents off-gassing from capacitors, condensers or switches. 3) Pressure Sealed Body. Airpura's unique pressure sealing of the filter chamber ensures that all of the air passes through the air cleaning systems filters. Other machines allow leakage and thus do not actually achieve the full 99.97% HEPA filtration rating, especially plastic store bought HEPA machines. 4) Steel construction. No outgassing from ABS plastic. Also, felt gaskets seals in the filter chamber to maximize filtration without using rubber gaskets to further limit off-gassing. 5) Larger Carbon Canister. Airpura units feature 18 lbs of carbon due to the 2 inch deep carbon canister. More carbon means more odor, VOC, and chemical abatement capabilities. 6) Warm rolled HEPA media. Eliminates cracking and tearing of HEPA media and guarantees higher filtration efficiency. 7) Superior Pre-filter design. 360 degree air intake, pre-filter can be vacuumed from outside the unit. Extends life of HEPA and Carbon filters. <br /> Specifications: Dimensions: 23" x 15" - Weight: 45 lbs. - 18 lbs. activated carbon, filter 13" x 13" x 9" - Carbon Bed: 2" deep x 570 sq'' surface * 40 sq. ft. true HEPA, 10 pleats per inch - Air Flow: 560 cfm on high - Coverage: Up to 2000 sq. ft. 2 air changes per hour. 1000 sq. ft 4 air changes per hour. - Pre-filter: 570 sq. in. x 1" - Housing: Powder coated steel - Voltage Options: 115 or 220 volts - Watts: 120 on high, 40 on low - Sound Level: 28.1 db on low (at 6 feet); 62.3 db on high - Approvals: ETL certified - Warranty: 5 years parts, 10 years labor.
