| Maintenance | The front panel pops off without tools; vacuum the washable pre-filter every 2-4 weeks. The carbon filter is replaced every 6 months and the True HEPA annually, and OEM filters are cheap and everywhere — a full year of genuine filters runs about $50, with quality third-party options under $35. Wipe the particle sensor lens (right side, behind a small door) every couple of months or auto mode gets lazy. No app, no subscription, no DRM chips on filters. | Front panel lifts off tool-free. The mesh pre-filter needs a vacuum every couple of weeks, and the washable AOC carbon filter should be rinsed and sun-dried every 3 months — that washability is why annual cost stays near $50 for the yearly Filter H kit (HEPA + fresh carbon). Wipe the sensor inlet occasionally. PlasmaWave is toggled with one button if you want it off. Winix has committed to producing 5500-2 filters through 2032 despite the model's discontinuation. |
