Now, Product Reviews aren't normally things I gravitate towards... they are not very literary for starters (and that's like 80% of what I tend to look towards in terms of criteria for a review), but for this little beauty, I've elected to make an exception.
My A/C was brutally murdered recently (more on that devastation, and the culprit behind it, to be discussed later), and we picked this up half out of desperation and half because we'd been eyeing it for a while because of the HEPA air filtration allergy-zapping potential. It was pretty pricey, I'll admit, a bit over $500...
But DANG, does it work miracles.
This is, unequivocally, the BEST fan I have ever encountered.
I will say that the allergy-busting HEPA filter aspect of it is less noticeably amazing, but part of that I feel is a) there's a limit to what magic can be worked when going outside frequently is a job requirement and I'm allergic to basically all of Outside (so it's somewhat difficult to tell what's native dust to the room and what I bring in) and b) it's likely something that will improve over the course of consistent running.
And honestly, the 'it cools my living area' aspect is the one that just blew me out of the water, so that's the part my brain is most fixated on.
It IS pricey, but I still HIGHLY recommend it.
