The Winix 5500-2 is a well-established four-stage air purifier for bedrooms and living rooms, built around a True HEPA filter and Winix’s PlasmaWave ionisation technology.
Key features
- 4-stage filtration — a washable pre-filter, odour-control carbon filter, True HEPA filter (captures 99.999% of particles down to 0.3 microns) and PlasmaWave stage work together.
- PlasmaWave technology — breaks down odours, VOCs and other pollutants without producing harmful ozone by-products.
- Automatic operation — the built-in sensor adjusts fan speed to current air quality, with a dedicated Sleep mode for quiet night-time running.
- 4 fan speeds — from a near-silent 27 dB up to a powerful 51 dB on maximum.
- Simple maintenance — the pre-filter is washable and reusable between HEPA filter changes.
