Venta LW15 Airwasher

“I've read the OG Ventas LW15, 25,45 are more reliable and easier to maintain vs the fancy wifi ones. I have a Smartmi humidifier, its Chinese made and works by the same concept - spinning discs over water to humidify the air. It has more electronics (connectivity and such) and fan isn't easily accessible- which for me is a downer. The main positive (for me) is that the individual discs are removable (unlike Venta) for ez cleaning. Are you using their solutions or alternate? I've read a bacteriostatic solution and rinsing aid are needed to keep the machine from getting gunky w/bacteria and mineral buildup.”
