Hard water and humidifier build up: What you should know

We all know a humidifier to be any device or equipment that helps to keep the atmosphere moist. When the air in your room is too dry, a humidifier is used, and it adds moisture to your dry air. Hard water is water that has high mineral content. The minerals include salts of calcium and magnesium as bicarbonates, chlorides, and sulfate. It is usually formed when water filters through deposits of limestone and chalk.

When you use hard water to produce the moisture for your humidifier, you may be causing more harm both to yourself and your newly purchased humidifier.

Hard water when used with your humidifier pollutes the air, introducing these minerals and chalk to your room air because your humidifier evaporates the water and releases the vapor into the air.

In addition to this, when you use hard water constantly over time for your humidifier, you should be sure to have the buildup of these minerals and of course bacterial when not maintained properly.

You do not want to have bacterial invade your air, especially if you are dealing with allergies. Also, misting of the hard water in your humidifier can result in the production of white dust, which can cause irritations and some breathing related issues when they are inhaled.

Is Humidifier White Dust Harmful to Health

White dust may not be a concern to most people, especially when they are not faced with allergy and asthma. However, it is a major problem when you have asthma, other lung/sinus health conditions, or allergy related issues. This white dust results from mineral content in the water that goes into a humidifier.

The hardness of your water determines how heavy or light the layer of the dust formed. Many, however, believe that the white dust produced is not harmful. They can be cleaned just as you would clean off other household dust. In most cases, only the ultrasonic and the portable impeller humidifier produces white powdered dust, and they are often not toxic, except only if you are allergic to it.

White dust generted from the humidifier in most cases are not dangerous to health as perceived by many. The hardness of a water only becomes a concern when consumed as a drinking water. Several reports have implicated hard water consumption in kidney stone formation, diarrhea, cardiovascular diseases etc. No standard research has implicated white dust formed from humidifier hard water with diseases.

There are several ways you can get the dust from your humidifier caused by your hard water. You could make use of a humidifier with a filter or purchase a demineralization cartridge which is designed to trap the minerals before they are released into your air. You can also consider investing in a warm mist humidifier. Otherwise, you eliminate hard water by using distilled water for your humidifier tank.

What is the Best type of Humidifier for Hard Water?

As earlier stated, the best humidifier for hard water is a humidifier with filters. You can use a cool mist humidifier with a filter. The function of the filter in a humidifier is to keep the moisture produced, clean. The filter will also remove the minerals from the water vapor before they are emitted from the humidifier, providing you with a clean and free air free from white dust.

Unfortunately, the filters can get clogged up quickly and thus calls for replacement. These filters are also quite expensive.

Another option is to go for a warm mist humidifier. However, one advantage a cool mist humidifier has over a warm mist humidifier is that it is safer to use when you have your kids around the house.

Investing in a water distiller is another great idea. The distiller will remove the minerals from your hard water. Although expensive, you can use it for other appliance that deals with hard water. One benefit of water distiller is that there will not be a need for frequent filter replacement, although it is advisable your water distiller is still subject to cleaning

A demineralization cartridge is another option you can think of considering. However, it is not safe to be used with a warm mist humidifier because of its heating element. In this option too, you will need to change the cartridges. These cartridges are also expensive but not as much as filters.

How to Prevent Humidifier Scaling (Mineral built-up)

Below is a brief and straightforward step you can take in preventing mineral build up, otherwise called humidifier scaling.

  • Turn off the power to your humidifier and unplug it from the electric outlet

  • Allow the solution soak for about 3 to 4 hours
  • Drain the humidifier tank and damp with a sponge. Rinse all removable parts in a running hot water
  • Clean the interiors of your humidifier with a cloth soaked in vinegar-water solution ensuring that all mineral deposit has been cleaned off
  • Ensure all parts are clean and dry
  • Re-assemble humidifier and fill the tank with distilled or filtered water.

Can I use soft water in my humidifier: Why not?

Any water is considered a soft water when it has less than 61mg per litre of calcium carbonate.

So, how do you tell if your water is hard or soft?

The easiest way to tell is by checking for scales on your household plates, glass ware or even the shower faucet. If that is a bit difficult, try to wash your hand with soap using the tap water. If it foams easily and slippery on time. Thats a soft water, if otherwise, the water is hard.
