| Maintenance | A layered stack — washable pet mesh, pre-filter, HEPA dust collector, and a carbon deodorization filter — runs roughly $80-120 a year, and the fabric side panels are removable and washable. The red flag is supply, not cost: owners already report replacement filters drifting in and out of stock at Samsung's parts channels, with almost no third-party alternatives. Air purifiers are a rounding error for Samsung's appliance division, and when a chaebol loses interest in a side product, the consumables dry up first. Budget a spare filter with purchase. | One cylindrical NanoFiber HEPA-plus-carbon filter swaps in annually at roughly $89, with a washable pre-filter you rinse monthly — simple, no subscription, no DRM. The catch with appliance-giant purifiers is parts longevity: LG cycles purifier models quickly, so stock a spare filter if you plan to run this past year three. Power draw tops out at just 41W, so 24/7 electricity is among the cheapest of any large-room unit. |
