vacuum scent

That technology is described as guarding against bad odors inside the vacuum and keeping the machine smelling fresh, helping the home smell fresher after cleaning.

Product details recommend replacing scented vacuum filters every 3 to 6 months or when performance declines. The listings also note that washing the filters will deplete their fragrance.

Many models combine HEPA filtration and an anti-allergen complete seal to trap dust and allergens. Scent features—such as odor-neutralizer cartridges or scented filters—are described as separate components that guard against bad odors and help the home smell fresher.

The listed USB diffuser has a 3.4 oz tank and can run for up to 6 hours of continuous use.

Listings state that a small dose is needed—specifically, use two capfuls per tank for effective cleaning.
