01 — Levoit
Best larger roomVital 200S-P Smart Air Purifier
Vital 200S-P is the step up for a room where pets add hair to the intake and more floor area needs cleaning. Its washable pre-filter catches larger debris, but the main filter still needs replacing. I would compare its published CADR and annual filter spend with Core 300-P before paying for the smart display and controls.

You have a small bedroom and limited floor space.

+Larger-room format and washable pre-filter

02 — GermGuardian
Best pet filterGermGuardian Air Purifier for Homes with Pets
AC4300WPT is the tall, narrow option when a round purifier would block a walkway or bedside area. The exact listing includes a pet-oriented filter and UV-C feature, but I would compare its airflow and filter replacement with the Levoit units before treating the light as a cleaning advantage. An optional technology is less important than enough air moving through a clean filter.

Reasons to avoid
−Filter and airflow comparison needs more work
−Replacement filters add ongoing maintenance
03 — Levoit
Best compact roomLevoit 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.

Reasons to avoid
−Smaller-room reach and ongoing filter cost

04 — Levoit
Best basic bedroomLevoit Air Purifiers for Bedroom Home Pets Dorm Room
Core Mini-P is for a desk, dorm corner or other small enclosed space. Its compact size and scent pad may appeal, but fragrance is separate from particle filtration and can be unwanted in a sensitive household. I would use it near the actual small space rather than rely on the listing’s broad room-area language for a living room.

You need a main purifier for a large room.

Reasons to avoid
−Limited scale for whole-room cleaning
05 — GermGuardian
Best simple towerGermGuardian HEPA Air Purifier - Large Room Air Purifier
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.
