H2OLabs Model-200 Countertop Home Water Distiller

Out of every model on the list so far, we chose this particular option because it’s quite budget friendly. But that’s not all, because it’s also compact, lightweight, easy to use, and made with an attractive modern design.

The filtering capacity is incredibly high with this water distiller, which is good because it can distill 4 gallons of water per day. But the overall process takes quite some time to finish, which means you really can only filter 3 gallons of water each day unless you feel like waking up in the middle of the night to add more water and turn on the unit.

H2OLabs Model-200 Countertop Home Water Distiller

The design is friendly, which is a big advantage. You do not have to be tech savvy at all to figure it out. So it’s a good choice for older people who typically find newer appliances and machinery tough to operate.

The device uses LED indicators to let you know when the filtration process is thorough. And even better, it’s quite easy to fill up this model.

What We Like

Customer service at this company is excellent. They are very professional, knowledgeable, and helpful to their customers.

What We Dislike

According to some customers, they feel that this unit is cumbersome and hard to manipulate and maneuver from time to time.

We love this water distiller because of how simple it is to use. Push a button, and you are immediately good to go. There is no need to replace any dirty filter cartridges, and the stainless steel and plastics are pretty much maintenance-free.This model is thermostatically controlled, so it automatically switches off to prevent burn-out when temperatures exceed 300ºF.

What We Like

This filter is fast and produces 0.4 gallons of distilled water in about an hour.

What We Dislike

The water tank in this unit is plastic. This is an environmental no-no, and many people will be turned off by this unfriendly water tank.

CNCShop Water Distiller Water Distillation Purifier

Even though this is also a very inexpensive option, it’s also a great value and an excellent piece of equipment. As a budget-friendly option, you’ll certainly agree that this is a top-quality water distiller in spite of its low price.

The capacity of this water distiller is 1 gallon. It’s a little slower than the previous one mentioned because it only distills 0.26 gallons of water every hour, which is 0.14 gallons slower, so the filtration rate is about medium because it’s not quite slow and it’s not exactly fast.

CNCShop Water Distiller Water Distillation Purifier

This model contains stainless steel condenser coils and a stainless steel internal steam chamber. All other components are made of plastic.

What We Like

The value of this model is excellent because it’s an inexpensive investment yet it works well and distills water at medium level speed.

An Explanation of Distilled Water

An Explanation of Distilled Water

You will get access to clean drinking water if you put it through a water distiller.

This is a process that separates harmful substances from the water through evaporation and condensation.Distillation happens when the elements are completely separated from the water, which means it will be 100% pure. It can also happen through a partial separation process, which means it’s not 100% pure.

When water is distilled the pH level is low. So the water is lacking oxygen, which means it is missing many of the minerals typically found in water because they were removed in the steam chamber during the distillation process.Some people, unfortunately, feel that distilled water has a flat taste to it. But if you have the right filter, you can add additional minerals and improve the pH level by increasing it. The taste will also improve if minerals are added to the water.

How Does the Water Distillation Process Take Place?

Water distillation happens when it is heated to a boil, turned into vapor, run through cooling coils at a low temperature, and this ultimately collects and stores the new water having removed all of the unwanted contaminants and vital minerals.

Water Distiller Maintenance & Use

When turning water into steam in a distillation unit, the contaminants that get left behind tend to get caught in the steam chamber.

Given enough time, your faucet will experience lime scale buildup and the boiling chamber will experience negative effects as well.

So, it makes sense to clean your water distiller regularly. When the time comes, consider these instructions:

Water Distillation Unit Maintenance & Use

  • Take the distiller lid off – remove the water distiller lid and soak it in water. Add a quarter cup of vinegar or lemon and lime juice into the water. Now pull off the lid and clean it with a scrub brush or a clean cloth to remove the limescale and other contaminants. You can also rinse the steamer and get any additional unwanted substances off of it before drying it with a cloth or towel.
  • Boiling chamber cleanup – create a solution of half vinegar and half water and use it to clean up the boiling chamber. Make sure you have enough solution to fill the chamber 2 inches above the mineral deposit line. Let it soak overnight and then rinse out the chamber in the morning and give it more time to dry completely.
  • Never use store-bought detergent – some people like to put commercial detergents in their water steamer. Sure, it’s going to clean it quicker than some of these other solutions, but the chemicals within it can be harmful to your health.

8 Reasons to Drink Distilled Water

Drinking distilled water provides many benefits. Some of our favorites include the following:

  • Barium free water – the chemical barium is often discovered in municipal water supplies. It’s known to cause heart problems and high blood pressure in lab animal testing.
  • The purest form of water – drinking distilled water is important because it’s incredibly pure. Around the world, members of the perfume, food processing, industrial, laboratory, and medical fields all use distilled water one way or another. These industries use this water because it filters the water better than any other method and the final product creates pure, clean, clear water every single time.
  • It’s the inexpensive option – out of the many ways to filter water these days, using a water distiller is not only better for your health, but it’s also less harmful to the environment, and it’s a heck of a lot cheaper than purchasing bottles of water from the grocery store.
  • Copper-free water – many of today’s municipal water supplies and water wells are known to contain the compound copper. If you continue to ingest copper for long periods of time, you’ll have a much greater risk of experiencing Alzheimer’s disease in the future.
  • Microorganism reduction – when water is boiled, it can kill just about every living microorganism on the planet. The water distillation process takes it a step further because when the water becomes steam, the microorganisms are kept out of it altogether. This means that any water distilled during this process is going to be free of microorganisms and completely pure.
  • Chlorine free water – most municipal water supplies use chlorine to treat the water. Most recently it has been linked with illnesses, so it’s obviously best to filter it out of your water. Distillation will cleanse your water of any unwanted chlorine, and if you replace the minerals, your water will be tasty, healthy, and really good for you.
  • Detox helper – if your body is filled with deadly toxins and you need to flush them from your system, you can do so best with distilled water. It’s very good to drink while you’re going on a cleanse to revitalize your health. Just remember to replace the minerals in the water to make it even more effective and potent.
  • Nitrate and nitrate free water – the beauty of drinking distilled water is that it will remove nitrites and nitrates from municipal water supplies and wells. These compounds are particularly unhealthy for the elderly and children. When ingested in larger quantities, they could even potentially be lethal.

Common Myths

As far as distilled water is concerned, a few myths are roaming around about its consumption. Whether new to you or not, you’ve probably heard some of these rumors and you could have possibly even believed them too.

  • Distilled water cooking removes minerals – many people are under the impression that cooking with distilled water will kill the nutritional value and remove much-needed minerals in the process. This is 100% false all the way around. You can cook with distilled water, steam with it, or boil it and the nutritional value of your food will remain the same.
  • Drinking distilled water has a flat taste – since all the minerals are being removed during the distillation process, there is actually some truth to this rumor because it will have a flat taste. But you do have the ability to add salts and minerals back into the water after distillation takes place and the water will have a much better flavor after re-mineralization.
  • Your mineral intake decreases drinking distilled water – again, as far as myths are concerned, this one is also true to a degree depending on how you treat your distilled water. During distillation, the minerals are going to be removed. But, if you drink regular water during the day instead of mineral water, your intake will only increase by about 15%. You also have the option to remineralize your water by adding salts and minerals to it after distillation has been completed.
  • It’s expensive to drink distilled water – this myth is so far from the truth that it’s not even funny. It is much cheaper than buying bottled water, first of all. Second, buying the distillation equipment is very inexpensive if you shop around or choose one of the inexpensive recommendations we’ve made above. Third, it requires very little electricity, so you’re only going to spend about $.30 or $.40 per gallon extra in electricity expenses.
  • Your teeth will become weak drinking distilled water – this is another major mistake and big common myth that many people fall prey to. Distilled water isn’t going to wear the enamel out on your teeth, and it isn’t going to ruin any fluoride in your toothpaste as well. But since the fluoride is no longer in the water, you will have less of it if you typically drink from the municipal water supply. So you can keep that one in mind if it applies to you.
  • VOCs aren’t removed during the distillation process – there is certainly some truth to this rumor. Since their boiling temperature is lower than water, these compounds aren’t removed during distillation. Although, if you use a distiller that also contains a carbon filter, the carbon filter will remove the VOCs from the water and completely clean up your water supply.

Is It Really Safe to Drink Distilled Water?

Absolutely. Not only is it safe to drink distilled water, but you can also cook healthy meals using it. It has a flatter taste as we’ve mentioned a couple of times, so it may seem weird to drink it at first. But eventually, you’ll get used to it.

Or you have the other option of adding salts and minerals back to the water to make it taste better. Just give it some time, and you’ll get used to the flat taste or figure out how to improve the taste by adding to the water supply.

The pH Levels of Distilled Water

You may have heard that the pH level of distilled water is slightly on the acidic side and you would have heard correctly. While water is neutral pH at seven, distilled water has a pH level of five, which is an acidic number.

But here’s the thing…

The average soda pop and other fizzy drinks have a pH level of 2.6 to 2.8, which is a lot less than distilled water. Your stomach pH levels are naturally 1 to 2, so again, the lower pH level in your drinking water is not a major issue. It’s a lot healthier than drinking a fizzy sugar drink, that’s for sure.

Purified Versus Distilled Water

When water is purified, it has less than 10 ppm level of contaminants. Water will typically be purified through water filtration, ion exchange, reverse osmosis, and other filtering types. This process is very effective, and it eliminates about 99.99% of water’s contaminants and makes it very pure.

The distillation process results in creating distilled water. This water has about one ppm level of contaminants. Simply put, distilled water is also purified water since the bulk of the contaminants are removed.

Contamination levels are nearly identical in both types of water. The mineral content is the bigger difference between these two filtering types. Purified water is going to have many more minerals than its distilled counterpart. But if you keep this in mind, you can always add more minerals to the water after it’s been distilled.

Spring Water Versus Distilled Water

Many online communities have varying opinions about the debate between distilled water and spring water. Some like to look at spring water as a superior option because it is a bonafide part of nature. But studies show that water coming from certain springs isn’t all that healthy because it contains contaminants like coliform, phthalates, and arsenic to name a few serious potential hazards.

On the other hand, many people will tell you that spring water doesn’t come directly from the spring. They say it’s just filtered tap water being shipped in plastic bottles.

Whether you purchase distilled water or distill it yourself, the chances of it being healthier and safe are much better than water coming from a spring.

Factors to Consider Before Buying

1. Your Specific Water Needs

You should start by asking yourself how much water does my household consumes each day? If you aren’t sure, try to take time to figure it out. Once you’ve established how much water you need, you will know what size of a distiller to buy.Small families can get by with countertop water distillers, whereas larger families will need to consider a larger water distiller. By purchasing the right-sized distiller, you can prevent the annoyance of always having to fill up the unit. Likewise, you’ll save money if you buy a smaller distiller, rather than buying a large one that you don’t need.

2. A Products Distilling Capacity

The distilling, or flow rate, is an essential factor to consider before you buy a water distiller. For example, the majority of countertop units will take between 3-5 hours to produce one gallon of distilled water.This may be sufficient to meet the needs of you and your family, if that’s the case, that’s great. If not, you’ll have to start looking at models with higher flow rates, models that can keep up with your demands.

3. Component Materials

When water is distilled, the distillation process involves high temperatures. Therefore, the right materials are crucial for the safety and purity of the water produced. The wrong materials could add toxins to your drinking water.Look for water distillers made from stainless steel and glass components exclusively. Both of these materials are tried, tested, and trusted. BPA-free plastics are also safe to use, as long as they are not heated up.

4. Energy Consumption

Almost every model of water distiller for sale on the market today will use electricity to heat water. Many models use less power than others, so if you want to be more eco-friendly, make sure you do your homework.Typically, a home water distiller uses around 3 kWh (kilowatt-hours) of electricity per gallon of water. Multiply your electricity cost per kWh by three, and you’ll calculate the cost of producing a gallon of distilled water in your home.

5. Price

It’s a rule of thumb that larger distillation systems will cost more than smaller water distillers. Also, those that have additional features will be more expensive. Only you know your budget, so weigh up the pros and cons and make an informed decision should be easy.

6. Carbon Filtration

The distillation process will filter out over 99% of impurities from your water. However, they do not filter out VOCs (Volatile Organic Compounds). This is because VOCs have a lower boiling point than water. Therefore, they evaporate with the steam from the water and cool as part of the distilled water.This is the reason that some water distiller manufacturers will offer a carbon filtration system as the final stage that water passes through post-distillation. This guarantees that all VOCs are filtered from the water completely. Whether you want to look out for models with extra carbon filters is your choice entirely.

Distilled Water FAQ

  • Is there chlorine in distilled water? If distilled and then the water passes through a carbon filter, 99.99% of the chlorine will be removed.
  • Do you just need to boil water to distill it? No, the process is more complicated than that. The boiled water becomes liquid to vapor, and then the steam became condensed and filtered and turned back into the water.
  • Is it safe for babies to drink distilled water? Yes, it’s safe for babies to drink this water and many experts even recommend it.
  • Is Distilled Water the Best Water to Drink? Generally, the answer is yes, distilled water is perfect for drinking. When drinking water is purified through a water distiller, the water produced is purer and cleaner than before. The water is also safe to drink. The only downside to drinking distilled water is that many of the natural minerals present will be eliminated during the distillation process.
  • How Often Should You Clean a Water Distiller? Use cleaning crystals every one or two weeks when scale builds up on your machine. If you live in an area with soft water, you won’t need to clean this often. People in the regions that have hard water will need to clean more frequently. Large scale build-ups will stop your distiller from heating water efficiently and can cause machines to break. Therefore, it’s important to keep then clean. 

Final Thoughts

Filtering water through the distillation process has been around through the ages. It has survived this long because it’s efficient, it works, and it’s effective too.

Water distillers are incredible products for those that want to drink the purest possible water. We personally recommend the ROVSUN Zokop 4Liter as our best water distiller for value, efficiency, and quality.For those of you who have slightly more substantial budgets, the Mini-Classic CT water distiller is an excellent product that has a reputation for lasting over ten years, creates excellent tasting water, and looks the part.We highly recommend all of the water distillers listed on this page and hope that this guide helps you to choose the perfect product for your needs.
