Clarifion Air Ionizer vs Wein Vortex VI-3500 Ionic Air Purifier

Both are plug-in ionizers with no filters to replace, so the choice comes down to coverage, control and track record. The Wein Vortex VI-3500 claims far more output and an 800 sq. ft. rating, adds app control and a pulsing mode, and is smaller and lighter. The Clarifion is a simple plug-in with a blue LED and no settings, and its 4.2 rating from 307 owners is a larger, more mixed sample than the Wein's 4.9 from 18. Buy the Wein for a larger room or for app control; buy the Clarifion for a small room and the simplest possible setup.

• Choose the Clarifion Air Ionizer if you want a no-settings plug-in for a bedroom, bathroom or hallway and prefer a product with a long, large body of owner ratings.
• Choose the Wein Vortex VI-3500 if you need to cover a bigger room, want app control and a pulsing mode, or want the smallest, lightest unit of the two.
