Who should buy which
Large open living spaces and allergy or wildfire-smoke households that want ultrafine-particle capture without an endless HEPA replacement-filter bill.
You want a quiet, compact bedroom unit or a budget pick: at 43 lb, 30 inches tall, and around $959 it is a large premium floor appliance, and the plates need periodic hand-washing.
Homeowners protecting a large basement, crawl space, or whole-house envelope from moisture, mold, and wood rot who want set-and-forget operation with a built-in pump.
You only need to dry a single room or small crawl space (the lower-cost HDi65 or Helios units are a better fit), or you want true HEPA or carbon air purification rather than moisture control.
