The Atrix VACHFIL Omega Plus Abatement Vacuum w/HEPA Filter & Light Kit is an excellent portable vacuum that has a self-contained HEPA filter cartridge for trapping lead dust, mold spores, and other hazardous particulates. The Atrix VACHFIL Omega Plus Abatement Vacuum w/HEPA Filter & Light Kit is made of high impact Starex flame retardant polymer for durability and longevity. 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.
