01 — Coway
Best automatic modeCoway Airmega Mighty2
The Coway Airmega Mighty2 listing identifies a HEPA filter, an activated-carbon stage and a particle-sensing automatic mode. It is more useful in a room where fan speed can adjust to changing particle levels; compare its published CADR and replacement-filter cost with the actual room size.

Best pet filterGermGuardian Air Purifier for Homes with Pets
This 22-inch GermGuardian tower has a pet-focused filter and a carbon prefilter. Its upright shape is easier to place beside furniture than a wide unit, but replacement filters remain a recurring expense.

03 — Levoit
Best larger roomVital 200S-P Smart Air Purifier
The Levoit Vital 200S-P uses a broad inlet and larger-room airflow, with a washable pre-filter for visible hair and dust. 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. Vital 200S-P Smart Air Purifier is the better fit for larger rooms with pets and room for the body; skip it if you have a small bedroom and limited floor space.

04 — Levoit
Best compact smart modelLevoit Vital 100S-P Air Purifier
LEVOIT Air Purifier for Home Pets Bedroom Dorm Room Washable Pre-Filter has HEPA filtration and app-connected controls. Vital 100S-P sits between Core 300-P and Vital 200S-P for someone comparing a rectangular pet-room layout. A washable pre-filter can help with visible fur, but the main filter remains a consumable and the smart controls do not replace room sizing. Check the model-specific cartridge, body depth and published CADR before choosing it over the round Core. Levoit Vital 100S-P Air Purifier is the better fit for pet areas where a rectangular body fits best; skip it if you want the simplest or smallest unit.

The GermGuardian AC4825E is a 22-inch tower with a particle filter, carbon layer and three fan speeds. Its recorded room figure of 153 square feet at 4.8 air changes per hour is a more useful comparison than the larger one-change-per-hour claim.
