Listings highlight specially coated or electrostatic fibers and “trap-and-lock” dust-busting strips as the main dust-capturing features.
Designs commonly use 360-degree swivel or flexible duster heads that wrap around obstacles, often paired with extendable handles (examples shown at about 3 ft and 6 ft) to reach high or awkward areas.
Some dusters come with a fixed (non-extendable) reusable handle, while others include extendable poles; listings commonly show extendable options around 3 ft and 6 ft.
The category includes disposable electrostatic duster pads/refills and reusable, machine-washable microfiber mop heads.
Pack counts vary; examples include kits with 1 handle + 5 dusters, kits with 3 or 4 refills, and refill packs offering around 11 refills.
