Review: Cleaning the humidifier daily is no longer a necessity! - Great filters making a visible change to using the humidifier! They remove the need to clean the device pretty much daily, which is an absolute relief! I’m still on the first one but I’m glad tracking the filter’s longevity in the app is a great convenience!
