Product review (5 stars): Great product and a must for keeping the Venta airwasher/ humidifier working great!
'well packaged and arrived on time.  It works very well and hope you never discontinue this.  I clean my Venta airwasher every 10 to 14 days and add this per instructed.  We use it in the bedroom and it's the best air purifier/humidifier I've ever used.  Excellent product.
