I have used SoClean 2 about 1 1/2 years. Just doing the cleaning and using a 7-stage water filter that makes alkaline water. In the past few months, I have had two bad sinus infections. Of the many things I am starting to do is replace the air filters and nares weekly. I am still using the filtered water. It seems that distilled water may help solving my recurrent sinus - not recurrent until this April. The humidifier does not have the scaley water as if tap water, but there is an 8th of an inch (about) in the morning. I will start pouring that out too. Thanks.
