Water Distiller Buyers Guide
What is Distilled Water?
You may see distilled water sitting on the shelf next to other bottles of water. While some may think that distilled water is better for them than tap water, you may wonder what it is and what the difference is.
Even though distillation isn’t a new technology, it remains one of the most effective water filtration methods.
Distilled water doesn’t differ much from filtered or purified water because it results in clean and safe water.
The main difference is that some filtered water contains minerals, whereas distilled water doesn’t have any compounds or minerals because it removes 99% of all impurities in tap water by the process of steam distillation.
Basically, distilled water is water that has been heated to remove all the impurities it contains to produce the purest form of water possible without any additional substances.
What is Distilled Water Used For?
Distilled water isn’t only for drinking. There are many other uses for this water, including:
Adding to Humidifier
It’s beneficial to add distilled water to your home’s humidifier. If you use regular tap water, you’re running the risk of mold growth.
Many love the purity of distilled water, which makes it appealing for drinking. You won’t find any harmful chemicals, contaminants, or pathogens when you drink distilled water. It’s an excellent idea to drink distilled water from a distiller that remineralizes because that improves its taste.
Doctors’ offices and hospitals use distilled water for various medical sterilization purposes. Because this water doesn’t contain any minerals, it doesn’t leave behind deposits when using it to clean instruments.
Corrosion or mineral build-up may occur if you add ordinary tap water to your vehicle’s cooling system. The lack of minerals in this water makes it a practical choice to use in your car. Distilled water is also an excellent option for rehydrating your vehicle’s battery.
Many canned foods are available with water mixed in with the can’s contents. These foods retain their color thanks to the addition of distilled water. If manufacturers used regular tap water, that could result in the product sitting in cloudy water. Regular water could also alter the taste of the food in the can.
You can prevent dry steam from splattering onto your clothing when ironing by using distilled water. Using normal faucet water in your iron can result in limescale build-up and corrosion inside your iron.
Other common uses for distilled water include:
- Hydrating cosmetic products
- Filling home aquariums
- Watering plants
- Cooking and baking
- Hair and skin hygiene
- Mixing baby formula
Overall, it’s super clean water that’s safe to use for different applications. We went over the safety basics of distillation here.
Benefits of Distilled Water
Because distilled water is contaminant-free, nothing alters its quality, smell, or taste. It’s beneficial to use distilled water in many areas throughout your home. Here are some of the most beneficial reasons for using distilled water:
No More Bottled Water
After making an initial investment in the water distiller, you don’t have to spend more on bottled water. If you typically purchase a lot of bottled water, that adds up to significant savings in the long-run.
Even if you have a small kitchen, countertop units don’t take up much space. These distillers are typically the same size as a coffee maker.
Cheaper Water Filtration Alternative
Water distillers are usually $100 or less, making them an affordable water filtration option. For example, some reverse osmosis systems can cost $1,000 or more. Water distillers do an excellent job removing the same number of contaminants as a standard filter.
No Bacteria or Viruses
Even though standard water filtration systems remove contaminants and other harmful pollutants, water can still pick up minerals from your home’s plumbing system. Distilling water ensures it doesn’t contain any pollutants or pathogens.
Using distilled water is an excellent way of detoxifying your body. Over time, minerals, chemicals, and other harmful toxins can build-up. Drinking distilled water helps flush these toxins from your body without causing any additional problems. When doing a distilled water cleanse, make sure you add more calcium and magnesium into your diet.
How is Water Distilled?
However, it’s an entirely different process when producing distilled water. While some do contain a carbon filter, many distillers can create purified water without them.
We go over the difference between distilled water vs purified water here.
The best water distiller is easy to use, and a beginner can handle producing distilled water after reading the instruction manual and setting the unit up. All you have to do is add water to the boiling chamber, where the water heats up to a boil. As the water creates steam, all impurities catch on a condensing coil. You get distilled water when the steam cools and is free of contaminants. While these systems can’t remove all pollutants, it can remove bacteria, organic chemicals, and minerals.
Here’s a breakdown of how the distillation process works:
- Step one: water heats up in the boiling chamber
- Step two: steam from the boiling water travels into a condenser
- Step three: the steam converts into liquid
- Step four: Impurities filter out of your water supply
- Step five: if you have a remineralization filter, this is when water flows through that
- Step six: the holding tank collects water droplets
What to Consider When Buying a Distiller
Depending on the type of filter in the distiller, it should result in contaminant-free water. However, some contaminants may remain. The top 10 best water distillers feature an activated carbon filter that removes VOCs.
Distillers are typically cost-effective, making them an excellent option for budget-conscious consumers. For example, you can find units for as little as $50. Keep in mind that every price bracket is going to include different features. It’s also good to remember that the most expensive distillers don’t always have the best reviews.
Countertop vs. Under Counter Unit
Most distillers feature a countertop design. However, if you have an outlet underneath your counter, you can keep these units out of sight. Be sure to check with the instruction manual to ensure that you can use the distiller underneath the counter. If you can’t use it as an under-counter unit, measure the space available on your countertop.
Some water distillers take between four and six hours to purify water. For example, the CNCShop water distiller takes one hour to produce just under one gallon of water. However, it takes up to four hours for Waterwise to make one gallon of water. Compared to the CNCShop water distiller, that’s a slow distillation speed.
The distillation process begins when you add water to the distillation chamber. Depending on the size of the distiller, it may feature a large or small chamber. That means, if you choose a unit with a small chamber, you’ll need to fill it more often. However, if you select a larger unit with a bigger chamber, that unit could take up more counter space.
The most common material you’ll find in water distillers is stainless steel. It’s best to choose a system containing a stainless boiling tank. It’s also best to make sure the condensing coil is also stainless. Those two elements and anything else coming into contact with the water should feature stainless construction.
Quality and Certifications
All water purification manufacturers can apply through third-party companies like NSF International or the WQA (Water Quality Association) for certifications. These third-party companies determine if the quality of the product matches the manufacture’s claims. While water distiller reviews give you a significant amount of information about the product, it’s still confusing to determine which manufacturer to trust. Look for reviews that link to information about the distiller’s certification.
Water Distiller Installation & Maintenance Quick Steps
Compared to other water filtration products, distillers are the easiest to install. Because they don’t require much set-up, it won’t be long before you’re enjoying the benefits of this water.
How to Install
- After opening the box, spread its contents on your countertop.
- Screw the handle onto the unit’s holding tank
- Flush the filters before placing them into the filter housings
- Place filters into their housings
- Plug the distiller’s cable into its back
- Add water and start the distillation process and throw away the first batch.
- Use a scouring pad to clean out the distiller and then refill with water.
How to Maintain Properly
Because the contaminants can’t leave the distiller, you must clean it regularly. You’ll also need to clean away limescale and other build-ups. Keeping the unit clean is the best way of preventing build-up from occurring. Avoid using household cleaning products because residue from them can remain in your distiller.
