Best Home Water Distillers Reviews

Pure Water Brand Mini-Classic CT Countertop Water Distiller (best overall)

Let's start with the most expensive distiller on the list, the Pure Water Mini-Classic, my choice for the best water distiller overall.

Pure Water is an American company that makes distillers for laboratories, medical facilities, organic food processing, and other commercial applications.

They also make a few distillers for home use, including two countertop models. The Mini-Classic Countertop Water Distiller is the smaller and more convenient of the two.

Pure Water Mini-Classic CT Countertop Water Distiller, stainless steel

Shop for the high quality Pure Water Mini-Classic water distiller at Amazon.

This unit has a solid build and excellent performance. Because it has a removable boiling chamber, it's easy to fill and easy to clean.

Is it fast?

Well, it takes about 3.5 hours to complete the distillation cycle. That's faster than most water distillers, and the fastest of the models in this review.

I do want to point out that the volume of one "batch" is not a full gallon. It's 3 liters, which is about 0.8 gallons. The glass container holds a gallon, but it won't be filled up all the way at the end of the cycle.

When the distillation process is finished, the machine shuts off automatically. It never boils completely dry, which protects it from damage. There's also a safety shut-off that will turn the unit off it it should ever overheat for some reason. 

One of the best things about this distiller is the stainless steel construction. You know it's going to last. In fact, the Mini-Classic has a 15 year warranty on the stainless steel parts plus a 2 year warranty on the electrical parts. You don't find many appliances with a guarantee like that.

Dimensions: 13.75" w x 15.75" h x 9.875" d

  • Glass jug
  • Automatic shut-off

Don't Like So Much

Waterwise 3200 Countertop Water Distiller (fastest electric distiller)

Waterwise 3200 distiller

See the fast working Waterwise 3200 at Amazon.

The Waterwise 3200 is an updated version of the Waterwise 8800, which was discontinued sometime in 2018. 

They took away the digital display, so it's no longer programmable. That's kind of sad, but it also means it's easier to use. Just push the reset button and it starts.

And the collection pitcher is now made of BPA free non-leaching Tritan plastic. It's a safer plastic than the old version, and it's crystal clear.

The outside of the removable boiling chamber is plastic, but the inside is stainless steel. Also new is a delay start fan, which makes it more energy efficient.

Now here's a really nice feature -

You can pull out the collection pitcher in the middle of the cycle if you need some water. It'll stop the dripping until you put the pitcher back in place. That's how a lot of coffee makers work.

If you want, you can buy an extra pitcher. That way you can keep one in the fridge while the other is hooked up to the distiller. Click here to check the price of the Waterwise 3200 replacement pitcher at Amazon.

It takes about 4 hours to distill one gallon of water with this machine. That's a good rate compared to others. And when the cycle is complete, the unit shuts off automatically.

This countertop water distiller comes with a 1 year warranty. At the manufacturer's website, they say that their distillers "typically provide three to five years of uninterrupted, trouble-free service."

Keep that in mind - the manufacturer doesn't expect it to last more than 3 to 5 years. That doesn't mean that it won't last longer. But it's not designed to last a lifetime.

The Model 3200 has been tested to NSF/ANSI Standard 62. This standard covers contaminant reduction as well as material safety, structural integrity, and total dissolved solids (TDS) reduction.

Dimensions: 15.5" w x 15" h x 10.5" d

Waterwise 3200 Pros and Cons

What People Like

  • Automatic shut-off
  • Won't operate if containers are not in correctly
  • Easy to use
  • Water tastes great

Don't Like So Much

  • Plastic collection pitcher
  • Made in China
  • Fan is a little noisy

H2o Labs Model 200 Countertop Distiller (best lightweight water distiller)

Next up is the Model 200 from H2o Labs.

This one is lightweight and easy to use. Unlike all the others, it has a holding tank that you take out and fill up at the sink. Then you put it back in the unit and flip the switch, and it starts distilling within minutes.

H2O Labs Model 200 water distiller

Enjoy the convenience of the H2o Labs 200. Shop now at Amazon.

Water from the holding tank automatically feeds into a boiling tray, which is much smaller than the traditional boiling chamber in the other models.

Also, the healing element is in the tray, in direct contact with the water. This is why it comes to a boil and starts distilling so quickly.

Another advantage of the design is that the boiling tray doesn't get hard scale buildup like the stainless steel chambers do. So that makes it easy to clean. You just take out the tray and rinse it. It's also dishwasher safe.

The BPA free plastic collection container/carafe holds one gallon of distilled water. You can order an extra from the manufacturer if you'd like to have an extra one on hand. That way you don't have to pour the water into another container in order to start another batch.

An automatic turn-off prevents the water from boiling out completely and burning the mineral deposits onto the heating element. 

For final polishing of the water, an activated carbon pod is mounted on the opening to the carafe. The manufacturer recommends replacing it after 30 gallons or 30 days. Pods are available from the manufacturer.

You'll also want to be aware that there is a part called an infrared anti-scale pad that will need to be replaced about every six months. This pad goes inside the heating element housing and helps minimize scale buildup. Replacements are also available from H2o Labs.

H2o Labs offers a One Year, 100% Parts and Labor Warranty to the original owner.

Dimensions: 11" w x 13" h x 10" d

H2o Labs Model 200 Pros and Cons

What People Like

  • Automatic shut-off
  • Fast Starting
  • Easy to use & maintain
  • Makes good tasting water
  • Energy efficient

Don't Like So Much

  • Plastic boiler and collection pitcher
  • Pricey replacement parts

Megahome MH943TWS Countertop Water Distiller (best low cost distiller)

The Megahome Model MH943TWS distiller is the least expensive of the bunch, but it accomplishes the same thing that all the others do.

It's a simpler setup and takes up less space on the counter. That's because the condensing coils and fan sit right on top of the boiler.

Megahome water distiller

See the budget-friendly Megahome water distiller at Amazon.

The boiler is made of stainless steel on the inside, and the outside is enamel coated steel. Water goes through a glass-lined nozzle from the boiler to the glass collection bottle, so the water never touches plastic at all.

It takes about 5.5 hours to produce one gallon of distilled water with the Megahome. That makes it the slowest of my top picks.

And, yes, it does have an automatic shut-off. You can start it before bedtime and wake up to a gallon of pure distilled water.

Megahome offers a 1 year warranty on parts and labor and a 30-day return policy.

Dimensions: 8" diameter x 14.5" h (distiller); collection carafe adds 10" to width

Megahome MH943TWS Pros and Cons

What People Like

  • Automatic shut-off
  • Easy to use & maintain
  • Makes good tasting water
  • Quiet
  • Affordable

Don't Like So Much

  • Doesn't have a shut-off button
  • Slow

Waterwise WW1600 (best non-electric water distiller)

If you’d like to be able to distill water without electricity, here’s a great option for you. The Waterwise WW1600 can be used with any type of non-electric heat source - a propane burner, charcoal or gas grill, or a wood or coal stove. 

Or, if you like, you can heat it on an electric stove or hotplate. So it’s an ideal water purifier for off-grid living or camping.

Waterwise WW1600 water distiller

Shop for this awesome off-grid water distiller at Amazon.

You can use it indoors, but keep in mind that it puts out a lot of heat and steam, so it might make the air uncomfortably hot and humid.

One of the best things about this water distiller is how fast it is. Instead 4 to 6 hours (like the electric models), the Waterwise WW1600 takes a little over an hour to distill a gallon of water.

The manufacturer says the yield is up to 3.2 quarts an hour, or 16 gallons a day. That’s the best case scenario. Factors like the type of heat source or weather conditions, if you’re outside, can affect the rate of the distillation process.

It’s made of stainless steel, and there are no moving parts to break, so it’s going to hold up for a long time. The only part you’ll need to replace from time to time is the rubber tubing. And, by the way, the tubing is made from high temperature food grade plastic.

So, how does it work?

You put 4 liters of water in the boiler at the bottom. Then you place the pre-assembled condensation trays on top of that and add a liter of water to each tray. Put the collection container of your choice on the floor and run the tubing downhill into that container. Then turn on your heat source and put the unit on it.

As the water in the bottom boils, steam rises, condenses on the trays, and drips down into a collection cup. Then that distilled water flows out the tubing into your collection container.

There’s a spout on the boiler so you can keep adding water continuously if you want to keep it going after the first batch. Of course, you’ll also need to keep refilling the trays, too. 

Besides the distiller and the tubing, you’ll get a digital timer when you buy one of these. That’s so you don’t have to stand there and watch it, since you don’t want to let it boil dry.

The design doesn’t allow for the addition of an activated carbon filter, so it’s possible there could be a trace amount of VOCs left in the water - if there were any there to begin with. If this is of concern, you could put the distilled water through a pitcher style filter.

Also, you should know that the manufacturer does not recommend using this water distiller with sea water. Although it is possible, doing so will void the warranty.

Waterwise offers a 2 year warranty on this product.

Dimensions: 12” diameter x 12” high

Waterwise WW1600 Pros and Cons

What People Like

  • Doesn't require electricity
  • Fast working
  • Use off-grid

Don't Like So Much

  • No activated carbon filter
  • Generates a lot of heat and steam

Here's a video review from Practical Preppers, if you'd like to see exactly how it works.

How to Choose a Water Distiller

To determine which is the best water distiller for your personal needs, there are a few factors you’ll want to consider:


How much distilled water do you need each day, and how long are you willing to wait for it? It can take anywhere from 3 to 6 hours to distill a gallon of water. Be sure to find out the length of the distillation cycle for the model you’re considering.

Power Consumption

Running a water distiller doesn’t use a lot of electricity, but budget conscious consumers like to know exactly how much it costs to operate their appliances.

To figure out the cost of distilling one gallon of water for a given model, first look to see how many watts it is. Multiply the number of watts by the number of hours it takes to complete a cycle. That number multiplied by .001 gives you the number of kilowatt hours (kWh). Kilowatt hours is the unit of electrical energy you’ll see on your electric bill.

Finally, multiply the number of kilowatt hours by the rate your power company charges. That number is the cost of electricity to distill a gallon of water.

Here’s an example, using the Megahome and a made-up kWh rate:

5.5 hours x 580 watts = 3,190 watt hours or 3.19 kWh
3.19 kWh x $.09412 (kWh rate) = $0.3002428

So, it costs about 30 cents per gallon in electricity.
If I make one gallon each day, it’ll cost me $109.50 per year.

Type of Materials

Most water distillers have a stainless steel interior, but other materials like glass and plastic might be used for other components. Pay attention to any parts that come into contact with the purified water, such as the filter housing, collection chamber, and lid. Choose the materials that match your comfort level.


Think about where you will store and use your water distiller. Check the dimensions and make sure you have enough room for it. Distillers tend to take up a lot of counter space. Plus you will need several inches of clearance around and above the unit.


Manufacturers may apply for certification with organizations like the WQA, NSF, or UL. These certifications are voluntary, and not being certified doesn’t necessarily mean that the product doesn’t perform well. But, when a product has one or more of those certifications, it can give you more confidence in making the purchase.


Always consider the warranty offered by a water distiller manufacturer, as well as the company’s customer support reputation. Be sure to read the fine print, and keep your receipt!

Water Distillers: Frequently Asked Questions

What can distilled water be used for?

Distilled water is used for a whole lot of things besides drinking water.

  • in small appliances like irons and diffusers to prevent mineral buildup
  • car batteries
  • hydroponics and water for house plants
  • laboratories
  • ice cubes
  • coffee, tea and juice
  • brewing beer
  • CPAP therapy machines
  • aquariums
  • neti pots

How do water distillers work?

Water distillers may have different bells and whistles, but they all work in basically the same way.

First, you put tap water into a boiling container. Turn on the machine, and it slowly brings the water to a boil.

As the water boils, it turns into steam. Contaminants are left behind in the boiler as the steam rises. Condenser coils collect the steam, and it reverts back to water. The purified water then drips into some type of collection bottle. 

The whole process mimics the hydrologic cycle in nature, only on a much smaller scale.

All commercial electric water distillers have an additional activated charcoal filter that removes any last traces of volatile organic compounds (VOCs) that might have survived the process. That filter will have to be replaced from time to time.

Which contaminants does distillation remove from water?

Water distillers eliminate most kinds of contaminants, including:

  • biological contaminants like bacteria, viruses and cryptosporidium
  • chlorine
  • arsenic
  • fluoride
  • lead
  • mercury
  • nitrate
  • trihalomethanes
  • dissolved solids (minerals, salts, metals, etc.)

Is distilled water safe for babies to drink?

Yes! Distilled water is a good choice for preparing baby formula because it's purified and doesn't have any dangerous substances in it. In fact, both the Mayo Clinic and CDC recommend distilled water for baby formula.

Doesn't distillation take beneficial minerals out of the water?

Distillation does take out all the minerals, including the good ones. Does that matter?

Well, most experts agree that it's not a problem because we get the vast majority of the minerals we need from our food, not from water. Some people say that taking all the minerals out can make the water taste "empty" or "flat". It might take a little getting used to.

If you want, you can put minerals back into the distilled water by adding a pinch of Himalayan pink salt, or a squeeze of lemon juice, or bottled mineral drops.

What are the disadvantages of water distillers?

Distillers are excellent water purifiers, but they do have a few negative points that you'll want to keep in mind.

  • They are very slow. It can take up to 6 hours to distill one gallon of water, depending on the model.
  • Distillers give off a lot of heat because they're boiling water the whole time. This might be nice in the winter, but in warm weather, it might make it uncomfortable in your kitchen.
  • The fan makes a constant noise while the machine is running. This may or may not bother you.
  • A distiller boiler needs frequent cleaning to avoid a buildup of the minerals and gunk that are left behind.

Verdict: Best water distiller for home use: Pure Water Mini Classic

All of these distillers are going to give you great tasting pure water. 

If you're trying to decide which one to buy, the key questions to ask yourself are:

  • How much do I want to spend?
  • How much distilled water do I need every day?

The longer the distillation cycle takes, the less water you'll be able to produce in a day. Of the electric models, Megahome is the slowest, Waterwise 3200 is the fastest, and the Pure Water is second fastest.

If you're on a tight budget, then the Megahome would be the best choice. It's the least expensive, but it does perform well and it has a decent warranty. I like the materials, too, and the fact that the water doesn't touch plastic.

For those who don't object to BPA free plastic, then the Waterwise or H2o Labs distillers might suit. The Waterwise 3200 is newly improved, and the H2o Labs 200 is the easiest to clean and maintain.

So, which is the best water distiller?

Overall, I'd say that the Pure Water Mini-Classic is the number one choice. It has the most solid build and it's one of the faster electric models. The manufacturer has a good reputation, and the warranty can't be beat. I think it would far outlast the others.

If you can afford the initial investment, I recommend the Pure Water Mini-Classic - it's the best water distiller for your money.
