As one of its daily deals, Meh offers the refurbished Winix 4-Stage True HEPA Air Cleaner (pictured) for $74 plus $5 for shipping. That's $6 under our December mention of a refurb and the lowest price we've seen in any condition. (It's $16 under the best deal we could find for a refurb elsewhere today.) It features 4-stage filtration, an air quality sensor, four fan speeds, PlasmaWave technology, and clean air delivery rate of up to 350 square feet.

Also available is the refurbished Winix Washable PlasmaWave True HEPA Air Cleaner for $74 plus $5 for shipping. That's $19 under last month's mention of a new unit and the best price we've seen for this model in any condition; it even beats a refurb from last November by $22. (Meanwhile, it's a current low for a refurb by $81.) It features a washable true-HEPA filter, 3-stage filtration, PlasmaWave technology, and a clean air delivery rate of up to 350 sq. ft.

Note: A 90-day warranty is included with each, although it's unclear who backs it.
