The Atrix VACGFIL Omega Green Supreme Vacuum w/HEPA Filter & Light Kit is the quietest most powerful service vacuum available. The Omega Green Supreme is made from high-impact starex flame retardant ABS polymer for durability and longevity. It features a new motor that uses 20% less energy, a HEPA Filter that is 99.97% efficient at 0.3 microns and comes complete with all accessories listed below. This vacuum also features the Red LED filter indicator light that improves the safety of this vacuum. This light is located on the rear panel and will illuminate once the filter is reaching full capacity. The user can then change the filter to avoid any overflow or materials. The new light meets the strict British standard number 8520, which is required on all fine filtered HEPA and ULPA vacuums that are used to remove asbestos, lead paint dust, or other similar dangerous materials. Changing the filter at the right time on a timely basis can provide many benefits such as increased filter efficiency, improve the lifespan of the vacuum, and reduce filter costs.
