Types of Water Distillers
Distillers generally fall into two categories. One relies on electricity and sits on your counter, while the other requires an external heat source.
Countertop Distillers
Countertop distillers are the most common choice for home use. You simply plug the unit into an electrical outlet, fill the reservoir, and hit a button. The machine heats the water into steam, which then condenses back into liquid form, leaving contaminants behind.
These units are convenient for daily use and require very little monitoring. However, they rely on electricity, meaning they won’t work during a power outage unless you have a generator. They also tend to process water slowly, so planning ahead is necessary.
Pros
- Convenient push-button operation
- No external heat source needed
- Compact design
Cons
- Requires electricity
- Can take hours to process one batch
Non-Electric Distillers
Non-electric distillers look a bit like heavy-duty cookware. You place them over a heat source, such as a gas stove, wood stove, or campfire.
These are excellent for emergency preparedness or off-grid living. Since they don’t have internal heating elements or motors, there are fewer parts that can break. However, you cannot set them and forget them; you must monitor the heat source and the water levels manually.
Pros
- Works without electricity
- Ideal for camping or emergencies
Cons
- Requires manual monitoring
- Often bulkier than electric models
Factors to Keep in Mind
All distillers use the same basic physics to purify water, but the user experience varies wildly between models. Here is what you should consider before buying:
Intended Use
Determine why you need the distiller. If you need a consistent supply of clean water for your kitchen, an electric countertop model is the most convenient choice. If you are building an emergency kit or plan to distill water while camping, a non-electric manual unit is the better option.
Water Capacity
Check how much water the unit can produce in one cycle. Most countertop models produce one gallon per cycle. If you have a large family, you may need a unit with a faster processing speed or a larger holding tank to keep up with demand.
Portability
Consider where the unit will live. If it stays on your kitchen counter, weight isn’t a major issue. However, if you plan to move it between a vacation home and your main residence, look for a model with a handle and a lightweight plastic body rather than heavy glass components.
Materials Used
Pay attention to what touches your water. Many users prefer stainless steel interiors and glass collection carafes to ensure the water never touches plastic. While high-quality BPA-free plastic is safe, glass and metal generally offer better durability and flavor preservation.
Budget and Running Costs
Calculate the long-term cost. While the initial price tag matters, you should also consider the cost of electricity and replacement carbon filters. Some budget models may be cheaper upfront but less energy-efficient over time.

Water Distiller FAQs
Does Distilled Water Taste Different?
Yes, it usually tastes “flatter” than tap water. Because distillation removes minerals like calcium and magnesium, the water has no flavor profile. If you miss the taste, try chilling the water in the fridge or adding a squeeze of lemon.
Do I Need the Minerals the Distillation Process Removes?
You do need minerals, but water isn’t the most efficient source for them. You get the vast majority of your daily minerals from a balanced diet of fruits, vegetables, and whole foods. Drinking distilled water will not cause a mineral deficiency if you eat well.
Is a Water Distiller Worth the Money?
Yes, if you want pure water without the plastic waste. While there is an upfront cost for the machine and a small cost for electricity, it is significantly cheaper per gallon than buying bottled water. Plus, you never run out of supply.
How Long Does It Take to Distill Water?
It is a slow process. Expect a standard countertop unit to take between 4 to 6 hours to produce one gallon. It takes roughly 10 times longer to distill water than it does to simply boil it.
Will Distilled Water Leach Minerals From My Body?
No, this is a common myth. There is no scientific evidence that drinking distilled water leaches minerals from your bones or cells. Your body regulates mineral levels efficiently through your kidneys.
Are an Alcohol Distiller and Water Distiller the Same?
They are similar but operate at different temperatures. Alcohol boils at 173°F, while water boils at 212°F. While some manual stills can do both, electric water distillers run too hot for making quality alcohol and are not safe for that purpose.
Are Water Distillers Only for Drinking Water?
No, distilled water is incredibly useful around the house. You can use it in steam irons, humidifiers, CPAP machines, and car radiators. Using distilled water prevents mineral buildup (scale), extending the life of your appliances.
Is Drinking Distilled Water Healthy?
Yes, it is perfectly healthy for most people. It is simply water with the impurities removed. It is an excellent choice for anyone looking to avoid chlorine, lead, bacteria, and other tap water contaminants.
How Long Do Water Distillers Last?
A well-maintained distiller can last 10 to 15 years. The heating elements are durable, and there are few moving parts to break. The most common maintenance item is replacing the carbon filter, which is cheap and easy to do.
What Are the Disadvantages of a Water Distiller?
The main downsides are time and energy. Distilling is slow, producing water drop by drop. It also uses electricity to boil the water for hours, which adds a small amount to your utility bill. Additionally, the process removes minerals, leading to a flat taste that some people dislike.
Is Reverse Osmosis Water the Same as Distilled Water?
No. Reverse osmosis (RO) forces water through a membrane to filter out contaminants, while distillation boils water and collects the steam. Distillation is generally more effective at killing bacteria and viruses, while RO is faster and uses less energy.
What Is the Best Water Distiller Brand?
Brands like Megahome and VEVOR are top contenders. Megahome is renowned for its UL safety listing and build quality. VEVOR offers excellent value and durability, particularly with their stainless steel and non-electric models.
How Often Should I Clean My Water Distiller?
You should rinse the boiling chamber after every cycle to remove loose mineral deposits. A deep clean with vinegar or a descaling solution is recommended every few weeks, or whenever you see stubborn scale buildup on the heating element.
