Here are the steps to fill the water tank of the Air Innovation humidifier model A1-KS30U-06C:

1. Turn off the humidifier and unplug it from the power source.
2. Remove the water tank from the base of the humidifier by lifting it straight up.
3. Flip the water tank over and unscrew the cap from the bottom of the tank in a counterclockwise direction.
4. Fill the tank with clean, cool water. Do not overfill the tank; leave some space at the top to prevent spills.
5. Screw the cap back onto the bottom of the tank in a clockwise direction until it is snug.
6. Turn the water tank right side up and carefully place it back onto the base of the humidifier. Make sure it is seated properly and securely.
7. Plug the humidifier back in and turn it on.

Once the tank is filled with water, the humidifier should operate normally and begin adding moisture to the air. It is recommended to clean the water tank periodically to prevent buildup of mineral deposits and bacteria.

The sputtering may be caused by a calcium build up the water system. To solve the problem do the following.

Turn the unit OFF and unplug it.

Empty any remaining water from the tank.

Mix a 50/50 solution of Distilled White Vinegar and Bottled Distilled Water (enough to fill the tank).
Pour solution into the tank and allow it to sit for 1 - 2 hours.

Plug the humidifier in and turn it ON. Allow it to run until the tank is only half full. If the sputtering has not stopped, turn the unit OFF and allow the unit to soak over night.

The next morning, turn the unit On and run for 20 minutes. Turn the unit OFF & unplug it. Pour out the remaining solution and refill with Bottled Distilled Water. Run the unit for an hour. This will flush out the lines. After that, it should run normally.

I would highly recommend using Bottled Distilled Water in the future, rather than Tap Water.

Hope this helped you to solve the problem.

It may be clogged with mineral scale. Empty the water that you now have in the tank and refill it with a 50/50 solution of White Vinegar and Bottled Distilled Water. Let it soak for several hours and then turn the unit ON. If it starts working as it should. let it run another 5 minutes, turn it OF and empty the tank. Refill the tank with Bottled Distilled Water and allow it to run at least 45 minutes to flush the system. After that, if you do not detect any vinegar odor, you can continue to use the remaining Distilled water.

If the unit didn't work as it should have after several hours of soaking. Turn the unit OFF and let it soak overnight. If this solved the problem, I would recommend that you continue to use Bottled Distilled Water for normal operation, rather than tap water.

Hope this helped solve the problem

Hunter carefree humidifiers use a reusable and washable wick this method of humidifying does not produce a fine mist like many centrifugal (cool misting)humidifiers. The fact that it is producing cold air seems to indicate it is working. However it would not hurt to check the water intake for blockages it also a good idea to run these models on high for several mins when starting this ensures that water is being pumped up.

Fill Water Tank.

Turn off humidifier and unplug the power cord from A/C outlet. Remove tank from

base. Turn upside down and unscrew filling cap. Fill tank with clean, cool, distilled,

filtered, or tap water. Do not attempt to fill unit through Vapor Nozzle. Water temperature

should NEVER be too hot or too cold. Extreme temperatures can damage the

unit. Tighten filling cap firmly. Return tank to base and let it sit for a few minutes. For

first time use or when replacing the demineralization cartridge filter, please soak the

filter in warm water for several minutes.

FILLING THE WATER TANKS
1. Before filling the water tanks, push the POWER switch to the “OFF” position and
unplug unit. Refer to cleaning instructions.
2. Remove water tanks from base, turn each tank upside down and remove tank cap
by turning counterclockwise. Fill tank with clean cold tap water.
Replace the tank cap by turning clockwise. Tighten firmly.
3. Carefully pick up tank, since it will be heavy when full, and slippery if wet.
4. Place water tanks on base. Make sure tanks are properly placed, otherwise, the
humidifier will not work correctly.

Mine also cracked along the seam several years ago. I sealed the crack using two-part waterproof plastic epoxy (found at any hardware store.) Not really pretty to look at, but it hasn't leaked since!

Located My Manual:
Hope this helps!

1. Remove tank from base. Turn upside down and unscrew filling cap. Fill tank with clean, cool, distilled, or tap water. Water temp should NEVER be too hot or too cold. Return tank to base and let sit for a few minutes. Be sure the filling cap of the tank is tightened firmly.

2. Plug power cord into a 110-120V AC wall outlet only. Turn power switch to "on" position. Power light will illuminate. Turn mist nozzle until desired level is being released. Aim nozzle away from furniture and walls.

3. Always turn humidifier off when water runs* out. Unit will continue to operate when tank is empty.
*Humidifier will run up to 12 hrs on low; 6 hrs on high.

DO NOT LET WATER SIT IN TANK FOR LONG. THIS CAN ENCOURAGE BACTERIAL GROWTH.
Place unit on level surface away from direct sunlight.
DO NOT ADD MEDICATION OF ANY TYPE INTO THE NOZZLE, BASE, OR WATER TANK.
ALWAYS LEAVE ROOM DOOR PARTLY OPEN. DO NOT MOVE, TILT, OR EMPTY WHILE OPERATING.

Mild bleach and water solution for cleaning, never detergent.
Clean every 3rd day during use. Clean after long storage
Humidity varies from room to room. Aim for 30 - 50% relative humidity. If windows/ walls fog or frost, reduce mist intensity. If room too humid, ventilate by opening door or window; adjust mist intensity.

The filter should be located below the tank. the tank should lift off of the unit and there should be a rectangular cavity where the filter fits. You will most likely find the old filter dried up and filled with a white crust. That is salt and other minerals in the tap water that the filter catches.
