Product Overview

The H12 400HB offers convenient whole house coverage in a single bottle design. It adds invisible moisture to your home by moving dry air through a saturated wick. Maintaining proper humidity levels between 30-50% in your home/office/workplace has been scientifically proven to help prevent the flu and allergies.

Can tap water be used or is distilled water required?

Asked by Don February 13, 2021
2
Answers

Hi, Don. Poor water quality can greatly affect your wick’s performance. While using filtered or distilled water is not required, we do recommend distilled water if you notice issues with your wick. Adding our bacteriostat to your evaporative humidifier’s water can also help control bacteria growth and extend your wick’s life. Thanks! -Natalie, Team AIRCARE

Hello, Mark! CL means 'child lock.' To deactivate this setting, hold the power button down for five seconds, the CL will blink, and then clear from the screen. If the issue persists, follow the steps above, and then turn off the humidifier. Thanks! -Melissa, AIRCARE

I also wondered about this and the only answer I can come up with is there must be about the same capacity in the area the wick soaks from.

Is this shipped with a wick or do I have to purchase separately?

It has a pull out container, holds about 2.5 gal. Has handles on each end, easy to fill if you have a deep sink and a tall spout, or you need to use the hose provided. Pulls out from the top

Did its job! Humidified as stated in the description. It is quiet enough for my family that it is used in the main living space. I breathe alot better, reduced the dryness from electric heating system used for our heat. It works fine, and for the purpose we bought it for. The delivery was exceptional also, we purchased online and was in perfect condition and on time.

I purchased this humidifier to increase moisture around a large area of wood flooring. It did a great job the whole family is feeling better this winter.

It is noisy on higher speeds. The only thing I don't like is its hard to tell when the bottle is getting full. You really have to pay attention. It would be better if it was a clear plastic.

I had a Bemis before which had two tanks. This struggles to keep humidity in a 1600 foot house at 30. I have to fill the tank every day. Also the Check Filter light comes on…. the filter does not need to be changed after one month, and it does not go off. Hello
