Developed to meet the needs of the popular daytime cleaning trend, the QuietClean 4.5Q Sealed HEPA Allergen Upright is a re-engineered, single-motor cleaner with True Balance brushroll and an innovative, sound-dampening system. This LEED Compliant and CRI Green Label certified, bagged cleaner combines a clean-air system with the ultimate in filtration: sealed HEPA. Synthetic media filters 96.75 percent of allergens down to 0.3 microns for cleaner air. The 13″ cleaning path, long 40′ cord and convenient, clog-resistant tools mean less stopping and starting to plug/unplug and look for tools. Commercial upright vacuum also features a 4.5-quart allergen disposable dust bag.
