How to Make Distilled Water for Drinking at Home – Benefits & Costs

drinking waterHead into any gas station and you’re likely to pay $1.50 or more for 20 ounces of water. Some of this water is labeled “pure,” but such a distinction can be misleading. It might be spring water, it might have been purified by reverse osmosis, or it might have been steam distilled.

Not only is bottled water more expensive per ounce than gas, it’s also bad for the environment. In fact, according to Mother Nature Network, bottled water produces 1.5 million tons of plastic waste each year. All this plastic takes 47 million gallons of oil to produce, and only 20% of these plastic bottles are ever recycled.

Your best option? Stop wasting money on bottled water. Pick up a reusable water bottle, and fill it with perfectly pure, steam-distilled water that you distill yourself.

What Is Steam Distilling?

Many people don’t know they can easily steam distill water at home. Steam distilling is the process of boiling water in an enclosed container in order to capture the steam and reliquify it in a connected container. As the steam rises, it’s collected in a separate glass or plastic container. When the water in the first container has been boiled entirely away, all that remain are the minerals, chemicals, and other contaminants that were in the water.

The water that fills the second container is nothing but 100% H2O, with zero contaminants or minerals. Once you’re ready to make another gallon, simply clean out the minerals and chemicals that were left in the distiller, fill it with water again, and turn it on. In five to six hours, you’ll have another gallon of perfectly pure water.

Why Drink Steam Distilled Water

nutriteam water distillerMy family is genetically predisposed to get kidney stones. I got them as a teenager, but I’ve since learned to modify my diet so I don’t develop them. However, when we moved to our first home five years ago, I developed kidney stones within three months. A CT scan in the emergency showed plenty of the hard stones lurking in my kidneys.

A doctor told us it was probably the water, which was highly calcified in my new town. So I started buying steam-distilled water to keep all those minerals out of my body. But at $0.88 a gallon, it was an expensive addition to the grocery bill – especially since my husband and I both drink almost a gallon a day. And I hated using all that plastic.

Eventually, we researched steam distillers online, and finally bought a Nutriteam Countertop Distiller. After we made our first gallon, we discovered that the doctor was right: There was a ton of white powder left at the bottom of the distiller. This was very likely the debris that had caused my kidney stones.


  1. Saves Money. If you don’t want to drink your tap water, distilling it at home is much cheaper than buying bottled water.
  2. Convenient. Before we purchased our steam distiller, we had to go to Walmart once a week for water (since they had the cheapest price). I didn’t like going because it was one more stop we had to make – and lugging around a dozen gallons of water in wintertime is just not fun. Now we simply distill two gallons of water each day right in our kitchen.
  3. Healthy. Steam-distilled water is completely pure; if you’re worried about chemicals or minerals in your water, you can eliminate these concerns with steam distillation.
  4. Great for Emergencies. If your tap water is tampered with, or your town goes under a “boil water” advisory, you’re covered. Steam distillers purify any type of water, including water filled with mud or even hazardous waste. As long as you have access to electricity or a generator, you have a source of safe, drinkable water.


  1. Extra Work. Though minimal, there is some extra work involved in steam distilling. You need to clean out the distiller, and over time the steel canister can become crusty (at least, mine did). However, most distillers come with a rust-removing cleaner, and it’s straightforward and easy to do.
  2. Upfront Costs. Steam distilling costs money, especially up front. There are monthly costs too, as it takes electricity to run the distiller, and your break-even point could be years out if you don’t regularly make use of your machine.

The Costs of Steam Distilling

1. The Distiller
First, there’s the steam distiller itself. On Amazon, the distiller I purchased sells for $219, which is not cheap. It comes with a plastic collection tub, but if you want to upgrade to a glass collection jar (to avoid any chemicals leaching into your water from the plastic), this costs an additional $45.

Here’s the good news though: While I can’t speak for every steam distiller out there, I can tell you with certainty that the Nutriteam distiller I bought is worth every penny. We’ve operated this distiller for 6 to 12 hours per day for the past four years. It has never broken or given us any trouble. So far, four years of perfect operation has broken the cost down to $54 per year.

2. Electricity
There’s also the cost to run the distiller. My distiller uses 2.9kW of electricity to make one gallon of water. I pay $0.09 per kW, and it takes around five to six hours to distill one gallon. So it costs me around $0.29 to make a gallon. However, I was paying $0.88 per gallon at Walmart, so that’s a significant difference.

Breaking Even

My estimate, based on what we spent upfront and monthly on electricity versus how much we were spending at Walmart on water, is that it took us around 10 months to break even. But that was several years ago, so the steam distiller has more than paid for itself since.

Final Word

If you’ve never tasted steam-distilled water before, you should buy a few jugs at the grocery store to make sure you like it. Steam-distilled water is different because it’s completely pure. Most other waters, even “pure spring water,” have a distinct flavor because they contain trace amounts of minerals.

Personally, I love the purity of distilled water because I know I’m not getting any minerals or chemicals I’m not supposed to. It’s just pure water, and to me, all other water tastes strange now. I haven’t had a kidney stone since I began steam distilling, and I don’t think I will again.

Do you distill your own water? If not, have you ever considered it?

    You might wish to check your calculations for the cost as your units are not consistent.

    If you mean that the unit uses 2.9 kW of power (that’s about the same as one or two electric kettles, say 25 amps) and it takes 5 hours to make 1 gallon of water, your energy consumption is 5 * 2.9 = 14.5 kWh. If your cost of energy is $0.09 per kWh (NOT per kW), the cost is $1.30 per galllon.

    otoh, if you mean that the unit uses 2.9 kWh of energy over the 5 hour period, its power consumption is about 600W (close to that of a typical refrigerator); and indeed the cost of the water is approximately $0.29 per gallon.

    I’ve read that distilled water draws out minerals from your body. I wonder if you have experienced any deficiencies after having consumed DW after so many years. I have been drinking DW for 4 days now and still continue to do research but some say its the best while others say its detrimental to your health. What have you experienced..truthfully????

      Think about it. If you use distilled water to make soup, tea, coffee, boil legumes, or further process food, you are adding minerals and other “additives” to the distillate. Distilled water DEMANDS to absorb nutrients. And all those supplements in your body have already blended with the water in your system, which is 80+% of your body weight. I have been using distilled water for a very long time. I add Swanson minerals, but am convinced that adding brown rice or any other mineral absorbant substance will fill out the overall profile of minerals demanded by distilled water. It absorbs what we eat. Not what we theoretically need to finance a USDA daily requirement. Which is BS to begin with. You may disagree. So what? : )

    • Johnny

      yes, destilled water isnt as good as filtered water because it doesnt have the minerals that normal water has and destilled water is super-absorbed by your cells because of osmosis and thus causing a possible cellular explosion which in a big scale can cause a lot of problems

  • Dr X

    my personal opinion only but: drinking only distilled water will result in long term harm due to 1) lack of minerals and 2) the absorption of CO2 into your distilled water

    That’s an old wive’s tale about leaching minerals. According to leading health expert Andrew Weil, M. D.the amount of minerals leached out of your body in a day from drinking three quarts of distilled water can be replaced by eating a single grape. Some people add a small amount of dolomite clay powder or Celtic or Himalayan sea-salt to get a better mix of minerals than what you get in reprocessed tap water, and filters don”t get the drug and anti-biotic residues out, where distillation does.

I have sold and installed 5-stage reverse-osmosis filter systems in people’s homes for years, and have used that same system in my own house for over 25 years. I have elaborate testing kits for determining hardness of water, chemical composition, and have just invested in testing for anti-biotic and traces of other drugs, and from my own test results have decided to switch to a distiller, though I will continue to sell the filter systems, because people have to buy filter refills every year from me. If everyone goes distilled, I’m out of business. Something to keep in mind when you see filter-system companies talking about distilled water leaching minerals. Just a tip.

    • GreatGazoo

      So you are selling snake oil?

      • Joseph de Nicola

        No, just 4 and 5 stage reverse-osmosis water filtration systems. I’m not saying they are bad, they do remove more than 99% of all impurities and minerals from common tap water, and much more cheaply than distillation, but I have become convinced that distilled is better still. In either case, I got Hinckley & Schmitt distilled water delivered to my house for 5 years, and then switched to RO water for another 25 years, because it was much cheaper, and almost as pure. Now that I can afford it, I’ve switched to a distiller, which is still way cheaper than having it delivered. I am in exceptionally good health, and notice that the veins in my hands are soft and supple like a very young person, whereas many friends and acquaintances of my age have very hard, stiff veins. I believe that drinking minerals in excess of nutricious need, that have not been absorbed through plants can build up as arterial and veinous plaque, leading to hardening of same. This condition has been positively shown to be a factor in heart attacks and strokes.

      Leeching? no. Diluting, yes. Water toxicity is an actual health concern.

  • Manuel de Moustache

    lol you’re supposed to drink minerals they are necessary for living. that is why you’re supposed to remineralize the water after distillation

    • trololololo

      over 90% of mineral come from fruits, veggies, etc. also pure water is better cuz it absorbes unused waste form body not the minerals already integrated to the cells

    I’ve learnt over the last few years that if a product says ‘stainless steel’ and not ‘100% stainless steel’, then it is likely not pure stainless steel but has nickle mixed in. It’s a very common practice adding nickel to stainless steel and advertising it as ‘stainless steel’. The only countertop water distiller I’ve seen where the water chamber says ‘100% stainless steel’ is the one from H2O Labs. Having seen how popular the Nutriteam distiller is and its excellent user ratings as far as its operation goes, I nearly bought it till I read a couple of review on different sites where people said that after extended use of this water distiller their doctor found too much nickel in their body. It was a timely reminder to me about how commonly nickel is added to stainless steel. I don’t know how many people have considered the long-term effect to their health if there is nickel in the boiling chamber of their water distiller. I would hate to use a distiller for 5 or 10 years then find out that’s the case. As it is, I haven’t purchase a distiller yet. Am still doing my homework and looking for the best price. But the water chamber must say ‘100% stainless steel’ or I’m not buying.

    Further to my comments on the potential for huge amounts of wasted energy ( dependent on whether DW is actually a health benefit or not ).

    The issue with domestic appliances is likely to be that they are unlikely to recoup the huge amount of latent heat energy available when the steam is condensed ( in order to heat incoming cold water ) anywhere near as efficiently as a centralised producer may be able to. An efficient design would likely have a counter flow heat exchanger thereby keeping the temperature difference between the opposing streams as high as possible theoretically leading to a good efficiency. I doubt somehow that anyone has managed to fit a good heat exchange design in a $100 dollar appliance of small size – maybe so but I doubt thats what the company who made the appliance had top of their list somehow.

    Hello every body my name is Micheal Brown a citizen of Nepal.
    i am here to publish to the world how i became rich after selling my
    kidney to one Doctor Williams, we met on internet and negotiated on buying one of my kidney and i accepted to donate one of my kidney for money which brought him buying one of my kidney for 300,000 dollars
    and even paid me half of this amount before the operation took place here in India and the balance was given to me cash after the operation,now i am bold to say i can never be poor again in life.
