As one of its daily deals, 5StarDeal offers the "factory-serviced" Oreck XL Professional Air Purifier, model no, RAIRP, for $78 plus $2.99 for shipping. That's $89 below the lowest total price we could find for a new unit. (We saw a refurb for a buck less in August.) This 3-speed device features a 6-stage filtration process, permanent filter, night light, fragrance tray, and purportedly cleans up to 600 sq. ft. in one hour. Deal ends today.

Note: 5StarDeal labels this device as both new and factory-serviced. No warranty information is provided.
