GermGuardian AC151 Air Purifier vs GermGuardian AC5600WDLX Air Purifier

Both are GermGuardian HEPA purifiers with three speeds and an ultra-quiet low setting, so the choice comes down to room size and features. The AC151 covers more space, adds a UV-C option, a nightlight, a child lock and an 8-hour timer, and is the better pick for a bedroom or living room. The AC5600WDLX is smaller and lighter with a carrying handle and an optional ionizer, which suits a desk, dorm or small office. Owners rate both well; the AC151 has the larger review base and a slightly higher rating.

• Choose the GermGuardian AC151 if you want to clean a larger room and value the UV-C option, nightlight, child lock and timer.
• Choose the GermGuardian AC5600WDLX if you need a compact, light unit with a handle to move between small rooms and want an optional ionizer.
