Brisk Pillar Kit (now with Mobius!)

Brisk Pillar is our quick-to-tape, quick-cleaning budget CR Box for small-medium rooms. Taping around the filters and top/bottom plates takes less than 10-minutes. Kit now includes premium UL-registered CoolerMaster Mobius 120P Black 2400 rpm pressure fans boosting CADR to ~200cfm (3-fans) or ~260 cfm (4-fans). This beats large retail HEPAs on their medium speed, while being another 10dB quieter and half the energy usage! With 4 filters providing a higher ratio of filter area to fans than the 2-filter Luggables, the Brisk Box is even more energy efficient and filters should last 18 months under typical conditions! Brisk Pillar covers up to 6 occupants at 40 cfm/person or 420 sq ft. Note: 4 Mobius 120P fans with 200,000 hour MTTF bearings approach performance of earlier 6 SickleFlow 1800rpm version of this kit -- Sickleflow have been discontinued by factory. Four 12x20" (or 12x24") filters to match the 4-fan kit are sold separately.

Brisk Box panels are precision cut from the same 'indestructible' corrugated plastic used for signs and USPS mail totes. Unlike cardboard, foamboard or hardboard, these tough panels won't be damaged by repeated tapings. You can order the panel with fans pre-assembled so you only need to tape the filters, or save $20 by assembling fans yourself with included push pins, fan grills, cable harness and zip ties. Brisk Box Kits include white duct tape, 12V DC Barrel from 120V AC wall plug.
