Buy the Airsoap
I've had my Airsoap for over a month now and I love it! The light indicator and occasional sound of it trapping contaminants let me know it is working. I just moved into a new house and the basement is rather musty. Or was until it spent some quality time with the Airsoap. I live in Colorado and the air quality has been terrible the last few years and will likely continue to be worse. I'm glad I have a reliable air purifier now! I have yet to clean the filter which is astounding to me, but also extremely convenient. Very happy with this purchase!
