💬 What real owners actually say
Synthesized from 2026 owner reviews & discussions across social media — the things spec sheets leave out.
True HEPA is non-negotiable. For pollen, dust and dander, only genuine HEPA filtration counts.
Match CADR to room size. An undersized purifier in a big room does almost nothing.
Run it continuously. Relief comes from constant air changes, not occasional bursts.
Watch filter costs. Replacement filters are the real long-term price — factor them in.
Skip ozone ionizers. They can irritate airways; filtration is what actually helps allergies.
Each slider sets how much each criterion matters to you (0 = ignore, 10 = critical).
