Hi HC,
Thanks for your feedback. We're so sorry to hear about your experience with your Canopy Humidifier and the delay with your subscription refills. We take feedback from our customers very seriously and I will be passing this along to our team.
We aim to ship out products within 5-7 business days of receiving an order. Unfortunately, our shipping timeframe may be elongated during the holiday season due to congestion with carriers.
The water probes are stainless steel and will not rust under normal conditions. However, calcium and iron from your tap water can build up on the water probes for units using particularly hard water, or in the event that standing water is left in the unit for an extended period of time, for example if a unit is unplugged while there is water in the tray.
To clean these probes, unplug your humidifier from the power source and wipe these down with a damp paper towel or melamine sponge.
The Canopy Filter was designed to collect and trap minerals, such as calcium and magnesium, found in most tap water, to prevent these materials from being dispersed into the air while your Humidifier is running. These minerals generally show up in your filter as discoloration of the white paper; some filters will turn pink if there's iron present in the water.
This discoloration is normal and is proof that your filter is working! If you have hard water in your home you may need to change your filter more frequently than our recommended 6-week cycle. You can do this by going to your account page, selecting Manage Subscriptions, and editing your Delivery Schedule.
Another option to reduce filter discoloration would be to only fill your Humidifier with distilled water, but for ease of use, I recommend using tap water whenever possible.
There's no need to remove the filter to dry it since your Canopy Humidifier will automatically shut off when everything is completely dry.
Hopefully, this information will help you maintain your Humidifier to continue enjoying its benefits!
