Best OverallA palm-sized plug-in ionizer that treats air with charged ions rather than a filter, powered from an outlet or USB. The maker's germ and odor claims come from the seller, and the weight is listed two ways.
A filterless tower air purifier that uses ionic purification and a washable collector instead of replaceable filters. The coverage figure differs between the specs and the description, and no HEPA filter is listed.
Popular PickA compact ozone generator for deodorizing smoke, pet and car odors, with generous stated coverage. Ozone work is for empty rooms, so this is a scheduled treatment tool, not an everyday air purifier.
A three pack of tiny ionizers for spreading light air treatment across several small rooms without filter upkeep. The filter type is none, and the listing gives no room coverage area.
A very small AC powered ionizer for a bedroom, office or kitchen corner where filter changes are unwelcome. It uses no filter, and the listing gives no coverage area, so treat it as a light add-on.
A compact ionizing air purifier for one small room, with two speeds. The filter is listed as general purpose with no HEPA rating, so expectations should stay modest.
A tiny plug-in ionizer meant to reduce everyday odors in a bedroom or small room without filters or refills. It claims odors only, and no particle or allergen removal is listed.
