Product review (1 stars): Self-Cleaning Didn't Work Well Enough for Me
I recently bought and installed a Zephyr Essentials Typhoon.  While it is an effective ventilation hood, the reason I am writing this review is to share that the self-cleaning feature did not work well enough for me.

I prepared some stir fry shortly after it was installed.  The grease in my pan was smoking and going into the hood.  The next day, I cleaned it per the directions.  Spray 409 into the blades while running on low and wait for it to return to the drain cups. Then empty the drain cups.  I did this four times that day and then three times the following day.  No matter how often I cleaned it, I could still smell the grease inside the hood.  Even weeks later, I could still smell the grease in the hood.

I am sensitive to smell.  This was the main reason I replaced my over-the-range microwave with a range hood - so my house wouldn't smell like what I had just cooked.  However, smelling grease every time I walk by the range hood is not acceptable to me.  I am replacing this range hood with one that has mesh filters that you can clean and run through the dishwasher.

Depending on your sensitivity to smell, this range hood may or may not work for you.  If you are NOT sensitive to smell like I am (my husband couldn't smell the grease after I'd cleaned it several times but I could smell it from across my kitchen) this range hood might work for you.  But if are sensitive to smell, you might want to consider a mesh or baffle filtered hood instead.
