Winix 5500-2 Air Purifier
For spaces up to 99㎡, this black unit balances performance with straightforward operation. It’s designed to handle allergens, dust, and odors without feeling overly technical. The 4-stage system starts with a washable pre-filter for larger particles, followed by a carbon layer to cut household smells. A HEPA filter captures 99.999% of particles as small as 0.1 microns—think pollen or mold spores. PlasmaWave tech is included, though you can toggle it off if preferred.

Auto mode adjusts fan speed based on real-time air quality readings, which some users find reacts slower to sudden changes. Manual control offers five speeds, including a 27.4 dB sleep setting that dims lights and minimizes disruption. At higher speeds, airflow is robust but noticeably louder, so placement matters in bedrooms.

Certifications from Allergy UK and AHAM back its efficiency, and the 390m³/h CADR means it can refresh a room in under 20 minutes. Filters need replacing every 6-12 months, depending on use. A few owners mention the interface feels dated, and newer models omit the remote. But for pet hair or seasonal allergies, it’s a solid pick—just don’t expect whisper-level silence on turbo.

With a 4.6/5 rating from 25k+ reviews, most agree it’s reliable if not perfect. Keep an eye on third-party filter costs, though the upfront price sits mid-range.
