DIY Distilled Water at Home: A Step-by-Step Guide for Purity

Editor: Diksha Yadav on Nov 06,2024

 

Distilled water is excellent for most applications, from drinking and cooking to keeping your humidifiers, plants, and even appliances working optimally. Purchasing distilled water is inconvenient and expensive if done over some time. Why not make it right at home? Making distilled water is pretty easy, inexpensive, and fulfilling. This article will guide you step by step so you know exactly how to make distilled water at home.

What Is Distilled Water?

Distilled water is purified water prepared through a process called distillation. In distillation, the impurities, chemicals, and contaminants are separated from it. When distillation takes place, the water boils and becomes a vapor; the impurities remain at the bottom. The vapors are collected and changed back into a liquid, giving pure, clean water.

This distilled water is helpful for several things, like:

  • Drinking (in case your tap water isn't trustworthy)
  • Cooking and making ice
  • Fill humidifiers
  • Water plants that are very sensitive to water
  • Using in-car batteries or cleaning appliances

Regardless of whether you have an addiction to minimizing household pollutants or want an additional source of fresh water, distilled water stands out as one of the purest types of water.

Advantages of Homemade Distilled Water

Homemade distilled water has several advantages:

  • Cost-Effective: Distilled water prepared at home will save much money in the long run compared to buying bottled distilled water.
  • Convenience: You can have distilled water at any time without running to the store.
  • Control Over Purity: Since you are doing the process of making distilled water on your own, you know how pure it will be; there will not be unwanted additives or contaminants.

Materials You'll Need

Making distilled water at home is a pretty straightforward process. You don't need special equipment. Here's what you'll need:

  • Large Pot: Ideally, one with a lid which can be turned upside down.
  • Small Heatproof Bowl: This is a bowl made of either glass or metal, sized to fit inside the pot.
  • Ice Cubes: To chill the lid to create condensation.
  • Tap Water: The source water you will distill.
  • Heat Source: A stove or hotplate to boil water.

How to Make Distilled Water at Home: Step-by-Step Guide

Follow the following steps on how to make distilled water at home.

Step 1: Prepare the Pot and the Bowl

  • Use a large pot and fill it with about 4-5 inches of water from the tap. Distill the water from this pot.
  • Float a small, heat-resistant bowl inside the pot on top of the water. This will be where your distilled water condenses and collects.

Step 2: Put on the Lid Inverted

It would help if you inverted the lid of the pot to allow condensation. This will help direct the condensed steam toward the bowl in the center. When steam rises and hits the calm surface of the lid, it will be condensed into water droplets and drip into the bowl.

Step 3: Place Ice on Top of the Lid

Pour lots of ice cubes on the upside-down lid. This chills the lid; actually, it facilitates the reversal of the steam back to liquid water at a faster speed. Thus, this step accelerates the rate of condensation in your distilled water and, hence, makes the distillation faster.

Step 4: Heat the pot and make it boil

Switch on your stove or hotplate to medium heat. As the water in the pot heats up, it will begin turning into steam. The vapor rises and hits the cold lid. This vapor then condenses and drips down into the bowl in the middle.

Make sure the heat is kept steady. You want an even boil-not too rollicking, as a splashing might introduce extraneous particles into your distillate.

Step 5: Observe the Condensation Process

You will see water droplets forming on the bottom of the lid. Watch the droplets accumulate and drip into the bowl. Add ice to the bowl as it melts to continuously cool the bottom of the lid and increase the rate of condensation.

This will depend on how much distilled water you need, and it might take you 30 minutes to a few hours. On average, an hour of distillation will produce about 1-2 cups of distilled water.

Step 6: Switch off the heat and collect your distilled water

Once you have distilled enough water in the bowl, let the heat go off then carefully remove the bowl off the pot. Be extra careful because the pot, as well as the bowl, is hot. 

You now have homemade distilled water, which is fresh and free from various contaminants. Pour it into a clean, sterilized bottle or container to be reserved for future use.

Different Methods for Producing Distilled Water

If you want to try a variation, here are a few different ways to make distilled water at home:

Glass Bottle Method

This requires two glass bottles, one of which will hold the tap water, and the other will catch the distilled water.

  • Fill one glass bottle with tap water.
  • Tape or glue the necks of the two bottles together using heat-resistant tape or waterproof adhesive.
  • Put the water bottle into the pot with boiling water. Let the other bottle be in the bucket with ice. Steam from the boiled water will condense and move into the colder bottle, and you will, thus, obtain distilled water.

Solar Distillation

If you stay at a place exposed to sun rays, then solar distillation can also be tried on you. Though this method takes longer it involves natural sun rays evaporating water.

  • Place a shallow pan of water outside in direct sunlight.
  • Cover it with a plastic sheet by adjusting it so that it drops all the water collected in a collection bottle.
  • Since water evaporates, all collected water on the plastic sheet will drip down into the bottle.

This is the simplest yet eco-friendly process to make distilled water from renewable energy.

Storing Your Homemade Distilled Water

Now, when your distilled water cools down, it would also be a good idea to store it appropriately. Please keep it in clean, sterilized glass or BPA-free plastic with a tightly sealed container. The water should be kept cool and preferably away from direct lights in storage. Metal isn't advisable as an option either because this type of water absorbs very fast. It can impact its purity.

Typical Applications of Distilled Water

Now that you know how to distill water from home, here are some practical applications: 

  • Drinking: Although some people like the taste of distilled water simply because it contains no impurities, remember that it also contains no minerals. Perhaps you might want to blend this with mineral supplements or dilute it with filtered tap water.
  • Humidifiers: Distilled water does not allow mineral build-up in humidifiers and, therefore, provides cleaner air.
  • Plant Care: Some plants, such as orchids and carnivorous plants, enjoy mineral-free distilled water.
  • Appliances: Distilled water prolongs the lives of appliances like irons and car batteries because it does not deposit minerals.

Frequently Asked Questions (FAQs)

1. Is distilled water safe to drink?

Yes, distilled water is safe to drink, but since it contains no minerals, it might taste flat. Some also think that the lack of minerals could have effects on health over time. Therefore, you may consider mixing it with mineral water or adding a pinch of salt to enhance taste and nutrient content.

2. How much distilled water can I make in an hour?

This quantity will vary according to your equipment and the size of your still. In general, for pot and bowl, it makes 1-2 cups per hour. It should make more in a more advanced setup.

3. How long does homemade distilled water last?

Distilled water stored in a clean, sealed container can last a couple of years. As always, keep it out of direct sunlight and contaminants in order to keep it as pure as possible.

4. Can I distill salt water?

Yes, but for drinking, freshwater is the best. Distillation from saltwater requires more energy and leaves much salt residue that can destroy your equipment if not correctly handled.

Conclusion

Making distilled water at home is a fantastic skill you can have for your fresh, pure water whenever you need it. And for following this guide you shall save money and acquire command over your water quality besides keeping your family and appliances clean from impurities. Thus, if you're careful and have all of your materials, making distilled water at home may end up being a very fulfilling do-it-yourself endeavor you and your house would actually enjoy.
