I booked 50 minutes of the Halo Air Salt Rooms from Lifebooker, at only $26. Really, less than I would spend on a night out, and much more purifying and relaxing. Yelpers generally give the place positive reviews as well.
I tried the place out of, well, curiosity, but specifically because I suffer from dry skin and am willing to try most treatments to help my skin at least once. While I am not sure yet how effective this is as a dermatological treatment (and reviews seem to suggest that ongoing visits are required to truly notice effects), I would say that besides being relaxing, I did breathe a lot easier while in my salt cavern. For anyone who needs a bit of relaxation and has $30 and an hour to spare, and especially for anyone with respiratory issues, I recommend this place as an experience you need to try!
(Located at 133 W. 22nd St, between 6th and 7th Ave., Halo Air Salt Rooms is conveniently located in Chelsea.)
