Who should skip these
Skip the Windmill AC if you only need air cleaning. It is a window air conditioner rated for 250 sq ft at $289.00, and it does not clean the air in a room the way a purifier does. If that is your only goal, the Windmill Air Purifier at $268.00 or the Windmill Air Purifier Max at $378.00 is the better fit — the Max covers 442 sq ft.
Skip the purifiers if you need cooling. The Windmill Air Purifier covers 202 sq ft and the Windmill Air Purifier Max covers 442 sq ft, and neither one cools a room. For moving air without cooling, the Windmill Fan is $59.00.
The gaps are worth knowing before you choose. The AC costs $21.00 more than the Air Purifier, and the Air Purifier Max costs $89.00 more than the AC. The Air Purifier Max costs $110.00 more than the Air Purifier.
How to choose the right one
Start with coverage. The Windmill AC is rated for 250 sq ft, the Windmill Air Purifier for 202 sq ft, and the Windmill Air Purifier Max for 442 sq ft. If you are cooling a room, match the AC to that 250 sq ft figure. If you are cleaning the air instead, pick the purifier whose coverage fits the room: 202 sq ft for the smaller unit, 442 sq ft for the Max.
Then weigh noise and weight. The Windmill Air Purifier and the Windmill Air Purifier Max are both rated at 16 dB; the Windmill Fan is rated at 18 dB. On weight, the Windmill Fan is 2.5 lb, the Windmill Air Purifier is 7 lb, and the Windmill Air Purifier Max is 21 lb.
Price is the last check. The Windmill Fan is $59.00, the Windmill Air Purifier is $268.00, the Windmill AC is $289.00, and the Windmill Air Purifier Max is $378.00. The AC costs $21.00 more than the Air Purifier, and the Air Purifier Max costs $89.00 more than the AC.
