How to Make Distilled Water for Humidifier!


How to make distilled water for humidifier

I have already talked, on numerous occasions, how effective humidifiers are for dealing with dry air and breathing issues that come with it. Especially, during winter time when the heating systems dry up the air extremely. There are many benefits of a humidifier in the home. But, did you know that you can save more money if you know how to make distilled water for humidifier use?


Buying the humidifier is only half of the story. In fact, if you don’t use and maintain it properly, it can easily do more harm than good. Every single humidifier is susceptible to bacteria and mold development.


And, with ultrasonic humidifiers, there’s also the risk of mineral buildup and releasing harmful minerals into the air. There are two things that can cause this:

  • Irregular water changing and cleaning
  • Using mineral rich tap water

It’s simple math actually.


If you leave the water in the tank for too long or you don’t wash it regularly and properly, it will develop mold and bacteria will grow. Which, is extremely dangerous for breathing in. 


The second issue comes from using the tap water. It is hard, meaning it’s rich with minerals.


They can build up in the humidifier, especially on the edges of the steam nozzles. And, from there, they will be sprayed into the air you and your family breathes.

So, the best way to ensure your humidifier pumps out healthy, breathable steam that will actually improve your health, is to clean and maintain it regularly. And, use distilled water that is mineral-free.


But, that adds up to the overall cost of using a humidifier as distilled water doesn’t come free as the tap water.


But, my goal with this post is to determine if you can actually save up some money by making your own distilled water. And, how to actually make it.


Therefore, here are the most common methods of making distilled water that is mineral free and ideal for humidifiers.


HOW TO MAKE DISTILLED WATER FOR HUMIDIFIER USE


Glass bowl method

When discovering the ways how to make distilled water for humidifier use, one of the most used methods is the glass bowl method. You need items that you definitely already have at home. And, there won’t be any need to buy something additional.


You will need:

The first thing you need to do is to fill the pot with tap water. And, place the glass bowl in, without the water from the pot entering the bowl. 


It has to float and not touch the bottom of the pot. 


Once the tap water around the bowl starts to heat up, cover the pot with the glass lid. It has to be glass because if you use a metal lid, the water will pick up metal particles. And, it won’t be completely distilled). 


Also, turn the lid upside down and place some ice on top. This will allow the steam to condense faster on the lid and drop down in your bowl faster. That's because you provided a hot cold barrier 


When your bowl is filled enough, remove it from the pot. And, you have fresh distilled water. Which, is free of any minerals as they are left behind, down on the pot bottom. 

Things To Note


Since this method requires plenty of electricity to get just a liter of distilled water, my suggestion is lighting a fire in the backyard or the BBQ, and spending a day outside while you make your full winter season batch of distilled water.


For a better understanding of the whole procedure, check out this video:



Kettle, copper tube & glass jar method


This is a much more cost-effective way. That's because it turns vapor into water much faster. And, produces significantly bigger amounts of distilled water in much shorter time than the first method.


For this, you will need:


The science behind this procedure is very simple. Like with the previous method, you will let the tap water heat up. But, in this case you, need it to boil as soon as possible. Then, that mineral free vapor needs to condense and you have distilled water.


The first thing you need to do is bind the copper coil tube with the kettle. For that, you will use the rubber binding. Like the ones used for plumbing.


The other end of the copper tube needs to go into a glass jar. Which, needs to be below the level of the kettle, so that you don’t have condensed water returning back to the kettle.


Fill the kettle with tap water, turn the heat on, and that’s it.

Things To Note


Note: If you want to speed up the process even more, wrap the copper tube with an ice pack.


To get a better idea how this looks and how to do it, here is a video of the entire process:


Solar powered water distiller

This is the most cost effective method because once you build it, you will need absolutely ZERO money to make distilled water. 


It takes some minimal building skills to build it, and even I (a stay at home mom), have enough skills to build it (but with the help of the handy hands of my husband, probably, to be honest).


You will need just basic tools and one afternoon to build it, and there are tons of projects and explanations online. The easiest places to find plans is on kids survivalist/science websites. 


But, it all revolves around one basic design. A shallow water container with an angled glass over it.


The heat of the sun evaporates the water and it condenses on the glass. The sun heats up the water and makes it evaporate and condenses on the glass.


Which, because being angled, leads the build up water droplets down to the gathering area, where you have an output that leads to a jug. 


Simple as that!


And, to understand what I am talking about and to get the idea how to make it, check out this video which offers a slightly more complicated to build, plan, but it’s actually a long lasting solution that will make you forget about paying for distilled water for ever:

Final thoughts

Okay, now you have some ideas how to make distilled water for humidifier use at home. 


Keep in mind that the first method might not be so much more cost effective than buying distilled water, yet it will allow you to save your house budget at least a little.


On the other hand, the second method is much more efficient, but it still includes a slightly higher electricity bill, yet probably lesser than you would have to pay for a 3-month supply of bought, distilled water.


And, finally, the most cost effective method, the solar method, is the cheapest solution as it only includes the cost of parts needed for building it, but once you get it up and running, there are no more additional costs.


So, do the math, see which method is the most suitable one for you.  And, keep in mind that even if the bottle says distilled water, it doesn’t necessarily mean mineral-free water that will protect your health, as well as slow down mold development. Therefore, think twice.
