Not unanimous: ChatGPT picks Coway Airmega 250S; Claude picks Coway AP-1512HH Mighty.

The models' case: Contains 15 lbs of activated carbon and zeolite specifically formulated to absorb pet odors and ammonia, paired with 60 sq ft of True HEPA for dander. The models' main caveat: Completely lacks smart sensors, auto modes, or sleek aesthetics, featuring high upfront costs and noisy operation on higher settings.

Gemini Contains 15 lbs of activated carbon and zeolite specifically formulated to absorb pet odors and ammonia, paired with 60 sq ft of True HEPA for dander; its 5-year filter lifespan and steel build offer unmatched long-term heavy odor destruction.
Claude For serious odor it is unmatched at consumer level — 15 lb of activated carbon plus zeolite specifically for ammonia and pet smell, all-metal build, 5-year filter life; the choice for multi-pet or litter-heavy homes where odor is the real problem.
Where it falls shortper Claude Expensive, heavy, industrial-looking, no sensor/auto/app and a low airflow-to-price ratio — overkill and poor value if odor isn't your main issue.
per Gemini Completely lacks smart sensors, auto modes, or sleek aesthetics, featuring high upfront costs and noisy operation on higher settings.

Best large-room value — CADR covers roughly 600–1000+ sq ft, the 3-in-1 filter includes a genuinely thick carbon pellet layer aimed at pet odor, filters are inexpensive, and app/auto-mode control is clean; strong pick for a big living room with a dog.

Claude Best large-room value — CADR covers roughly 600–1000+ sq ft, the 3-in-1 filter includes a genuinely thick carbon pellet layer aimed at pet odor, filters are inexpensive, and app/auto-mode control is clean; strong pick for a big living room with a dog.
Gemini Delivers massive airflow (410+ CFM CADR) for rapid dander and hair turnover in large spaces at an outstanding value, supported by smart app integration and budget-friendly filter replacements.
Where it falls shortper Claude The carbon, while thick for its class, still saturates within months in heavy-odor homes and needs whole-filter replacement; app dependence annoys people who just want a knob.
per Gemini Thin carbon sheet filter struggles with heavy, concentrated pet urine or litter box odors compared to thick granular carbon beds.

The value benchmark for pet owners — true HEPA plus a real activated-carbon layer handles both dander and litter/wet-dog odor in rooms up to ~360 sq ft, with an eco-mode that shuts off in clean air and an air-quality sensor; a decade of reliability and cheap, easy filters make it the safe default.

Rank history
Just missed the top 5
GPT Austin Air HealthMate Plus — excellent odor and VOC filtration but too loud, bulky, and expensive for most pet owners · Shark NeverChange MAX — convenient long-life filter and good odor features but weaker independent performance track record than the top picks
Claude Coway Airmega 400S — excellent large-room dander performance and sensors, but pricier than the Mighty for a similar value proposition and lighter on carbon than the Austin
Gemini Blueair Protect 7470i — High CADR and sleek design, but expensive proprietary filters and complex electrostatic filtration offer lower long-term value · Levoit Vital 200S — Great budget performer with a top-loading washable pre-filter, but edged out by the HR900's pet-specific pre-filter sheets and the Core 600S's superior raw CADR capacity
