How Many Watts Does the Honeywell 50250 Air Purifier Use?

I recently bought the Honeywell 50250-S HEPA Round Air Purifier from Amazon. It was nearly half price from Amazon Warehouse Deals since it was a returned unit, but it was listed as “Like New” so I gave it a shot. It turns out the unit would not turn on, but after I took apart the control panel I realized that one of the wires of the power cable was loose. Once I connected it back to the right spot, it worked perfectly. Now I know why it was a returned unit.

The purifier seems to do a pretty good job at removing odors, but it is noisy and uses a decent amount of power. How much power? Well, the purifier has three speed settings: High, Medium, and Low, which you can select with the knob shown:


I used my Kill-A-Watt to measure how many watts the purifier used at each speed level:


So, as you can see, the High speed setting uses a whopping 200 W of power. Medium reduces the consumption to 165 W, while Low uses 103 W.

At $0.15/kWh, that means the air purifier would have a yearly cost of $263 on High, $217 on Medium, or $135 on Low if run 24/7 – not exactly insignificant, and all of which are more than what I paid for the unit in the first place!
