…without fear of ingesting chemicals that can harm your health.

So, how do you get the ideal water distiller that meets your home water needs?

We’re here to help you!

In this post, we’ll outline for you the 10 best water distillers for home currently available on the market today (plus comprehensive buying guide and TIPS on how to choose the best unit).

What’s a Water Distiller?

A water distiller is an electric appliance used to transform your contaminated tap water into 100% pure water through the distillation process.

As you already know, distillation is the process of removing contaminants in water such as heavy metals, salts, through the boiling process. The water is heated up to boiling point, and the steam it produces is condensed back to liquid to become the distilled water.

When the steam evaporates from the water, it leaves behind a solution of concentrated minerals and other contaminants.

A typical water distiller features an electric heat element (rated 1,000 to 1,500 watts) responsible for boiling water in a stainless steel tank.

The boiling process results in steam which then enters a stainless steel cooling coil—where it’s condensed to water.

Once your home distiller has boiled out all the water, a float switch will jump in to turn it off. You can then drain off the concentrated contaminants solution and refill it manually/automatically to continue with its job.

The best home water distiller should be able to remove more than 95% of the minerals found in water, including sodium, nitrate, sulfate, and arsenic. The distillation process also destroys all the bacteria, cysts, and viruses present in water.

Most of the units meant for home use come with a portable countertop design, connect to the 120V electrical outlet, and distill around 3-4 liters of water at a go.

However, some models are meant for permanent installation (say in your home basement). You simply integrated these units into your water supply line to distilled all your home drinking and cooking water. The purified water usually collects in a storage container from where it’s supplied to the tap, fridges, etc., with the help of a small pump.

Now that you understand what a water distiller is (and how it works) let’s shift our eyeballs to the TEN top-rated home distillers you can buy today…

What To Look For Before Buying?

Distillation Capacity

One of the top factors to consider when making a purchase is its water capacity. This usually depends on the cost of a given unit.

The capacity of a distiller is measured as the amount of water it can distill in 24 hours.

To get an idea of the best distiller capacity to choose, consider the amount of water you’ll be using at your home a day.

Construction Materials   

It is also important to look at the materials used to construct the unit you plan to buy.

Stainless steel and glass are usually preferred because they don’t leach chemicals into water under heat (during the distillation process). Besides, stainless and glass are incredibly easy to clean.

Though you might be tempted to go for plastic models due to their affordable pricing, we advise you against it.

And if you must buy a plastic distiller, make sure its BPA-free and food-grade. The last thing you want it a distiller that purifies your water and then contaminates it with even more harmful toxins.

Ease of Use/Maintenance

Another crucial factor to consider when buying a water distiller for your home is how easy it is to operate or maintain.

From our reviews section above, you can see that we selected the easiest to use models. All of them come with a single button operation, where you just need to press the button and leave the unit to do its job.

When the unit is done, it automatically shuts itself off.

For the maintenance part, distillers usually require cleaning as the only maintenance. There are no filter cartridges to be replaced.


How much to spend on a home distiller should also be a top consideration.

We suggest that you first come up with a budget of the amount of cash you’re willing to spend on a unit.

The general price of a home distiller ranges from $100 to $500 or more

If you make a reasonable budget, you’ll be able to get yourself a distiller that meets your home water distillation needs.

Even if you’re on a tight budget, you’ll still find a reliable and dependable model under $100.


The Manufacturer guarantee is also worth considering when buying a home water distiller.

Remember that these machines come equipped with electric components which can break down after a short period of time.

Ensure the unit you buy comes with a longer warranty. Manufacturers who offer you warranties for their products show how comfortable they’re in the quality and reliability of their products.

A warranty of 12 months (or 1 year) and above is acceptable.

PRO TIP: Distiller With Filtration!

Although distilled water does not need any filtering, some people dislike its tasteless nature. For this reason, some manufacturers are integrating their machines with activated carbon filter to help change the taste of water (and even remove any contaminants that might have been left). If you get a distiller integrated with a filter, go for it!

Why Distilled Water?

We’ve repeated it a thousand and one times throughout this post that distilled water comes with a load of benefits.

In this section, we’ll take you through the KEY benefits you’ll get from using distilled water made by your home distilled water machine.

Distilled Water Benefits:

1. It’s considered the purest water. As we mentioned earlier on, distilled water is regarded as the PUREST form of water all over the globe. Distillation takes water through the most natural purification process—where unwanted minerals and chemicals are separated from pure water.

The ultra-clean nature of distilled water is the reason why it enjoys worldwide use in laboratory, industrial, medicinal, perfumery, and food processing industries.

2. Fewer microorganisms. Nearly all the microorganisms usually present in tap water are mercilessly destroyed as water hits the boiling temperatures. This means that the steam that’s condensed and collected as pure water does not contain these elements, significantly reducing chances of waterborne distances.

3. Safely remove all the water contaminants

Apart from microorganisms such as bacteria and virus, the distillation process also does an excellent job of removing all unwanted chemicals present in tap water. These include the nitrates/nitrites, barium, Copper, fluoride, chlorine, arsenic, lead, mercury, and so on.

4. Great for detoxifying your body. Yes, distilled water can also help flush out the harmful toxins out of your body. It acts as a magnet that picks up all the rejected, unhelpful inorganic compounds and eliminates them from your body.

5. Distilling your own water is cheaper! You’ll all agree with me that making your own distilled water at home for drinking and cooking is way less expensive than buying bottled water. What’s more, bottled water can be harmful due to the plastic bottles used to package it.

Soo many benefits from the purest water known to mankind, right?

BUT…are there any dangers in drinking the same water?

You’ve probably heard some MYTHS about distilled water, which might have made you stop and think about using it in your home.

Let’s debunk the most common myths:

1. Distilling water strips it off the beneficial minerals, which can affect your mineral intake. While the first part of this statement is true, the second part doesn’t make sense. If you take 8 glasses of water per day, this will represent 15% of minerals intake…which is to say that most of your minerals intake comes from the food you take and not the water.

2. Drinking distilled water weakens your dentals. People who support this claim back it by saying that distillation removes fluoride from your water. However, the removal of fluoride will not affect your teeth in any way since your teeth already have enough fluoride. Furthermore, you’ll be brushing your teeth using fluoride toothpaste.

3. Distillation does not remove volatile organic compounds (VOCs) from the water. This might be true to some extent. And that’s because these compounds have a lower boiling point than water, meaning they’ll enter the boiling room as well. If you’ve installed filters in your faucet or your filter you buy a distiller that has a filter, they’ll get rid of any VOCs remaining in the water.

Frequently Asked Questions

1. What is the approximate cost of operation for a water distiller?

As an electrical appliance, you expect your water distiller to consume a certain amount of energy.

A standard home distiller with 4-5-liter capacity fitted with 1000Watt (1 kilowatt) heating element will provide you with a liter of distilled water per hour.


 the energy cost per each liter= electric cost per kilowatt-hour

if the energy cost in your area is 8 cents/Kwh, then the operational cost of your distiller will be 8cents per liter.

NOTE: accumulation of scales around your distiller heating element can lead to increased cost of operation as the element will need more energy to boil water. Though the scales are unavoidable, regular maintenance will help eliminate them.

2. What contaminants does distillation remove from water?

Water distillation removes plenty of toxins and contaminants usually present in water. During the boiling process, it effectively destroys biological contaminants (like bacteria, viruses, and cysts).

Other contaminants that a distiller will remove from your water include fluoride, lead, mercury, nitrate, arsenic, trihalomethane, and dissolved solids (like metals, minerals, salts, etc.).

3. What are the uses of distilled water?

Distilled water has multiple uses that you never know. In homes, it’s used as the drinking and cooking water. Other applications of distilled water include:

  • Laboratories (both chemical and biological)
  • Ice cubes
  • Making beverages, e.g., coffee, tea, juice
  • Brewing beer
  • Neti pots
  • Aquariums
  • Car batteries
  • Hydroponics
  • In small appliances like diffusers and iron to prevent minerals buildup
  • CPAP therapy machines

And so much more!

4. Does distilled water contain chlorine?

If water undergoes an efficient distillation process, about 93-95% of chlorine will be removed.

Passing the water through a carbon filter afterward will remove up to 99.9% of any remaining chlorine in your water.

Luckily, some distillers come integrated with the carbon filter to help remove any remaining chlorine from your water.

Final Verdict

Distilled water is the purest form of water known to humankind. It is 99% free of toxins and contaminants usually found in water. This makes it the safest water you can use at home for drinking and cooking.

Today, you can distill your home water in the comfort of your kitchen and save yourself a significant amount of money on the bottled water.

All you need is the best water distiller for home.
