| Maintenance | Coway's usual painless routine: one Max2 HEPA-plus-carbon filter a year (~$89) and a washable pre-filter you rinse quarterly, with filter-life tracking in the IoCare app. No subscription pressure, filters are widely stocked, and Coway's parts support is the most dependable in the industry. Note the wireless phone charger adds ~20W to the 47W purifier when in use. | 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. |
