The Electrolux UltraSilencer canister vacuum is one of the quietest machines on the market today. First introduced in the mid 2000s, the EL6986a offers premium filtration by means of a HEPA filter and micron pre-motor filter. While quiet cleaning is an obvious advantage of this Electrolux canister vacuum
, it's removal of household allergens and dust is another great quality in this machine. The UltraSilencer offers two options for HEPA filters: the EL012b standard filter and the EL012w washable filter which can be rinsed under water and dried before reusing it.
