Buyers Guide

Six Things to Consider When Buying a Water Distiller:

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 units, whereas larger families will need to consider larger units. 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 products 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 machines. 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.

Frequently Asked Questions

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 distillation, 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.
