Vornado MD1-0004 HEPA 2535

This product is more energy-efficient than many, which is a big plus for an item that many (like me) leave going 24 hours a day, due to bad allergies and asthma. These have helped my mom a great deal at her place, though she did have to return one unit that developed oily spots inside, then became noisy.

It's spring time, which equates to allergy time, so it was important for me to ensure that our Vornado air purifier was geared up to handle the pollen. I was so relieved to find that this HEPA filter were still being sold, since the actual air purifier unit has been discontinued ... thanks Amazon for making it easy to find! easy to order, and quick to ship. I've installed it and it's working as expected.

I used a watt-meter from my local power company and discovered the following: Depending on fan speed, low to high, my VAQS25 uses 50W, 93W, or 160W.

I normally use the lowest (and quietest) speed but sometimes must flip to high after feeding my wood stove if I'm not careful.

I'll be replacing my HEPA filter after three years of winter use (I only use it because of the wood stove). I've used my shop vac, a powerful one, to clean the filter a couple times, and the green light still comes on when I switch to high.
