01 — Coway
Best automatic modeCoway Airmega Mighty2
Coway Mighty2 is the higher-priced choice for someone comparing a lasting larger-room appliance rather than the cheapest filter box. I would verify the exact model's current CADR, filter stages and replacement pricing before paying its premium; the Airmega name covers several different machines. It deserves a place when the buyer can make use of the larger-room format and ongoing support.

02 — VOOPNU
Best basic large-room claimVOOPNU Air Purifiers for Home
VOOPNU is the last price-led alternative for a very small room after checking the exact cartridge, fan settings and return terms. An attractive room-size headline is not a substitute for comparable CADR evidence or a reliable replacement-filter supply.

03 — Levoit
Best bedroom choiceLevoit Core 300-P
Core 300-P is the comparison I would make for one ordinary bedroom where the larger Core 400S-P would crowd the floor. Levoit publishes an AHAM-verified rating for the exact model, but I would still compare its CADR and filter cost with the measured room rather than rely on a large maximum-area headline. Its straightforward controls suit a buyer who does not want another app.

04 — Levoit
Best smart large-roomLEVOIT Core 400S-P
Levoit lists a 231-cfm CADR for the Core 400S-P, a useful step up when the room outgrows the Core 300-P. I would place it where air can enter and leave freely and check the filter price before deciding that its smart controls justify the extra spend. An app is convenient, but the fan still needs to run at a speed you can tolerate.

05 — GermGuardian
Best slim towerGermGuardian AC4825E
GermGuardian is the familiar entry point for a buyer outfitting one ordinary room without paying for app controls. Its HEPA-labelled filter format makes replacement availability a practical part of the choice. I would compare the exact CADR or recommended room size with the real room rather than stretch a budget model across an open-plan floor.
