Anyone with experience with alen air purifiers.

I've wanted Alen for years. Got the 75i and 35i. 35i was fine, but not that impressed with odor removal and I have the ultimate filter. Small kitchen and if I cook a burger, the smell is still there in the morning-even on turbo. 75i makes a knocking sound even on the lowest speed and that is right o

Air purifier to address upper airway resistance during sleep?

That's not what the data shows. I've not tried the Alen, but I've tried several other air purifies, and have found the reviews on Consumer Reports and HouseFresh.com to be accurate. And based on those reviews there are other units that provide less noise for the same clearance rate. Specifically:SPE
