How to Clean Your Hey Dewy

1. Empty your device daily - minimize any standing water in the cup for extended periods of time.


2. Once a week use a small brush - gently scrub the spout area and prevent any build-up caused by your water contents that have inherent deposits.


3. Replace your filter every 4-6 months (depending on frequency of use).

• Carefully remove the filter from the cylindrical housing.

• Replace the filter and reconnect the tube to the lid.

No Mist?

• Soak the Device

It could be the case where the filter is not fully soaked before the device is powered on.
To resolve this, follow these steps:

1. Fill the device all the way up to the "Max Line."

2. Let the device sit and "soak" for two minutes before powering it on.

• Check the Filter

It could be the case where the filter either needs to be flipped over or replaced.
To resolve this, follow these steps:

1. Open the lid.

2. Pull the filter out of the cylindrical tube. Be careful not to remove the tiny spring at the bottom of the tube.

3. Check to see if the filter looks frayed/discolored.

• We recommend replacing your filter every 4-6 months depending on the frequency of use. New filters can be purchased here.

4. If the filter is frayed/discolored, replace it with a new filter. If the filter looks fine, flip it over.

5. Reconnect the tube to the lid.

6. Close the lid.

• Re-adjust the spring

It could be the case where the filter is not fully making contact to the upper portion of the device.
To resolve this, follow these steps:

1. Carefully remove the cylindrical tube from the upper lid.

2. Inside you will find a filter, place it to the side for now.

3. Beneath the filter, at the bottom of the tube, there should be a small spring. Find it and pull it out.

4. Carefully stretch the spring to increase the pressure of the filter against the upper portion of the device.

5. Place the spring back at the bottom of the tube, then the filter, then connect the cylindrical tube back to the device.
