Humidifiers are highly dependent on the water that is used on them. While any kind of water like tap water can be used on humidifiers, using it long-term may cause issues to your machine, as well as your health. This is because tap water has minerals that can clog your machine, and unfiltered tap water may cause contaminants that can transfer to your breathing air.

This is why distilled water is the best water to use for humidifiers. In general, any kind of distilled drinking water may be used for your machine. Distilled drinking water is treated to ensure that there are no mineral traces and contaminants in the water, therefore making it safe for your humidifiers from any gunk buildup in the tanks.

How To Distill Your Own Water

While distilled water is widely available in many stores nowadays, there may be times when you've forgotten to get a gallon or a few bottles to stock in your home. If this is the case, you can easily distill your own water and save your machine from being contaminated by other water types.

All you need for distilling your own water is time, patience, and a vigilant eye while watching your water boil. Here are the steps to distill your own water:

Things You'll Need

  • Large stainless pot with a clean stainless lid (about 1-5 gallons)
  • Oven-safe glass bowl (must fit inside your stainless pot)
  • Wire baking rack (optional)
  • Ice

Steps in Distilling Water

  1. Fill your large stainless pot halfway full with water.
  2. Place the oven-safe glass bowl inside the pot and let it float. Do not let it touch the bottom of your pot. If necessary, you can put the oven-safe glass bowl on top of a wire baking rack to elevate it inside the pot.
  3. Turn on your stove to a medium-low fire and heat the water to a low, steady boil.
  4. Place the stainless steel lid UPSIDE DOWN on your pot and fill the top with ice. The ice will turn the lid cold and cause the water vapor to condense on the bottom of your lid before dripping on your glass bowl.
  5. Let the distilled water collect in your glass bowl. Do not let your pot boil dry.
  6. Turn off the heat, and carefully remove your pot from the heat source. Wait for it to cool.
  7. The water inside the glass bowl is now distilled water. You can now remove it from inside the pot and pour it into another glass container for storage. You may also use this for your humidifiers as soon as it is already cool.

With this process, you should be able to distill your own water to use for either your humidifiers or even for drinking.

Using a humidifier for your home is a great way to improve the air quality of your home. Air that is too dry can cause several problems like dry eyes, sore throat, dry skin, or it can aggravate your colds and flu. A humidifier can quickly rectify these issues by simply increasing the moisture of the air around you. Here are the other benefits you can get from using one:

1. It can prevent influenza

According to this study, using a humidifier can help reduce the risk of catching the flu because humidity levels above 40% helped deactivate flu particles. This makes them less infectious, making the air in your space a lot safer.

2. Helps loosen congestion

Humid air adds moisture to nasal passages, which can help loosen up heavy and thick mucus. This helps your cough become more productive, helping release sticky or trapped phlegm.

3. Prevents dry skin

Dry skin can cause it to crack and wrinkle easily, and it can be uncomfortable especially for those who already have skin issues. A humidifier adds moisture to the air and keeps your hair and skin healthy.

4. It can reduce snoring.

One of the things dry air can do is to aggravate the airways which makes snoring worse. The added moisture in the air adds lubrication to your nasal passages and can help reduce snoring.

5. Humidifiers are great for plants and your home too.

These nifty machines aren't useful to just the humans in the house—even the plants benefit as well. Moisture-loving plants become more vibrant and fresh with the added humidity, and your wood floors and furniture will last longer. It also prevents static electricity from building up in your home.
