According to experts, a human being should take at least seven glasses of water per day. The question is, how clean is the water you are drinking? This article sheds light on distillation, one of the best and the oldest water purifying methods. While at it, we will review in detail the best countertop water distiller in 2021 and 4 others in its class, based on our extensive tests.

What is a Water Distiller?

In a nutshell, a water distiller is a device or an appliance used to purify drinking water. If you can remember from your elementary science class, water distillation is the process of separating water from impurities so you can have clean distilled water.

Water distillers comprises of a heating element, a boiling chamber, a condenser, a filter, and a container to collect the clean water. Once you turn on the distiller, the heating element heats the water until it becomes vapor and rises to the boiling chamber, leaving behind most impurities.

The steam then passes through the condenser, where it starts to cool down and turn back into liquid. To ensure the distilled water is completely pure, the best distiller passes it through a filter before finally collecting it to the container.

The most significant benefit of using a distiller to purify drinking water is that it's cheaper than buying bottled water, especially when you have a big household. This method is also effective on any type of water, even if you live in a place where there is salty water.

The drawback, however, is that distilled water is stripped of all beneficial minerals, and this can also make it taste flat.

Beauty aside, we found this distiller completely safe to use and it is FDA-approved. Unlike the Megahome though, this distiller gave us a gallon of distilled water every four hours, and that is the average time we found common among most countertop distillers. While most of the distiller is made of glass and stainless steel, the collection container has a plastic handle, so we did not burn our hands when picking up the clean water.

This Water Distiller from H2o lab is yet another gorgeous masterpiece made of stainless steel, a touch of BPA-free plastic, and glass. So, it did not look out-of-place on our kitchen countertop. While it does have some plastic components, the distilled water does not come into contact with it thanks to the innovative porcelain nozzle where water passes, to ensure we had no concerns over safety.

The tank has a one gallon capacity, and it only takes 6 hours to make a gallon of pure distilled water, which was longer than we liked. The model also comes with a carbon filter and a full-year supply of replacement filters to ensure us of thoroughly cleaned water.

  •  They also give you a full-year supply of the filters.This unit is very easy to clean because both the tanks and the carafe have large openings allowing easy access. 
  • The device also comes with a large jar of unique cleaning crystals to combat the scaling that can happen after distilling hard water.


  • The H2oLabs Water Distiller takes approximately 6 hours to give you a gallon of drinking water.
  • This is too slow, especially if you require a few gallons per day.It is a bit heavy, weighing about 10 pounds, so it's not the best for travel or RV use.

Its stainless exterior and glass water collector promote a clean but classic design that ensures it looks at home in our modern kitchen aesthetic. This is one of the few water distillers which the Underwriters Laboratory has approved, and we marveled at how effective and safe to use it is.

The beautiful countertop distiller can process 1 gallon of distilled water every 5.5 hours, so you can get at least 3 to 4 gallons per day. The capacity is sufficient for our moderate household uses. 


  • All interior parts are made of stainless steel, and the collection carafe is glass, so your distilled water won't be touching plastic anywhere.

Benefits of Drinking Distilled Water

1. Zero inorganic compounds. According to Allen E. Banik, M.D. Author, “The Choice is Clear”, distilled water is the safest type of water to drink because it contains no inorganic compounds. Water contains inorganic minerals that the human body cannot assimilate, and they end up causing harm to your arteries and kidneys in the long run. Those compounds include barium, nitrates, copper, and chlorine.

2. Fewer to no microorganisms. Bacteria, fungi, viruses, and all other microorganisms found in water are left behind and killed when water heats to over 150 degrees Celsius. The water distillation systems also removes metals and organic contaminants like pesticides from the drinking water. This ensures you are drinking very safe water.

3. Best for detoxification. Most people use bottled or tap water when doing a detox or a cleanse. Unfortunately, the water they use introduces more toxins into their bodies instead of getting rid of them. With distilled water, you are sure no toxins are entering your body, especially if you use an excellent distiller.

Is a Water Distiller Worth It?

One thing is for sure, water distillation systems are not cheap, but it's completely worth it. While other water purifying methods like boiling, reverse osmosis, and filtration are all good, only distillation gives you 99.9% purity in water. As for the cost, a water distiller will spend at most 40 cents per gallon, which is a drop compared to buying bottled water.

Factor in the fact that you are saving the world from all those plastic bottles, and you have a winner right there.

When deciding whether investing in a water distiller is worth it, consider other pure water uses other than drinking. For example, you should only use purified water in your humidifier, nose drip, and brushing your teeth. Using bottled water for all these can be quite costly and tap water is not always safe.

Why are Water Distillers so Expensive?

A good water distiller will set you back between $50 to $200 depending on the make, brand, and special features. If you compare this to your $30 high-end coffee maker, it can seem quite expensive. However, the best water distillers are made of extremely high-quality material to enable them to do what they do for a long time, up to 30 years. All the components and functionalities of a water distiller are also complicated, which is why the appliance costs that much. As we have said above though, a water distiller is absolutely worth it if you want to use pure water without breaking the bank and running the environment.

How to Choose the Best Water Distiller

When choosing a water distiller for your home use, these are the factors you should consider.

1. Capacity and output

How much water does the distiller hold in its tank, and what is the output per round? If you have a big household or people generally drink a lot of water, you might need something with a higher capacity like the Durastill 8 Gallon per day distiller.

2. Portability

Do you need a distiller for home use, or will you be traveling with it for adventures? If your answer is later, choose a more portable and lightweight unit.

3. Construction material

The only reason you are distilling water is to have it purified. It makes no sense therefore, to introduce more impurities in the water during the distillation process. Choose a unit made of stainless steel or aluminum and glass for safety purposes and stay away from anything made with plastic, even if it says BPA-free.

4. Your budget

Last but not least, consider your budget. While the best water distillers may be on the expensive side, you can still find a few budget models that don't compromise on safety, ease of use, and durability.

Who Makes the Best Distilled Water?

Megahome line of countertop water distillers undoubtedly makes the best-distilled water. The high-quality, plastic-free build and slow distillation make pure water taste good even without the additional minerals.

In Conclusion

There is a reason why water distillation has stood the test of time as the best water filtering method. A countertop water distiller brings convenience, safety, and efficiency right to your doorstep and ensures you have the purest form of water for your use. We hope that after reading these water distiller reviews, you can make an informed choice on which is the best water distiller for you.
