Water Distiller FAQs

What's included in the price?

Your Water Distiller is supplied with absolutely everything you need for six months of distillation:

  • Stainless Steel Water Distiller (choose black or white fittings)
  • Power lead
  • 4 litre collection jug (choose plastic of glass)
  • 250g residue cleaner
  • 6 active carbon filters

Where's the jug? 

Inside the distiller.

How much does distillation cost? 

The average water distiller uses around 3 kilowatt hours to make 4 litres of distilled water. This equates to an average electricity cost of 10p per kilowatt hour, therefore each litre of distilled water costs around 7-8p to make.

How long does it take to distill? 

Usually 5-6 hours for 4 litres of pure distilled water. You can shorten the time by using water from the hot water tap. Many customers fill it and leave it to run overnight as it switches itself off automatically.

316 vs Deluxe vs Professional, what's the difference?

All our distillers have the same heating and condensing elements. Between the Professional and Deluxe the only difference is that the outer body of the Deluxe is stainless steel and the Professional is powder-coated steel. The 316 is made from higher quality marine grade stainless steel which is capable of distilling seawater.

Will distilled water leach minerals from my body?

No. Distilled water forms a very loose body with carbon dioxide on contact with air to become very slightly acidic. Some people mistakenly imagine that distilled water can leach water from your bones. There is no scientific evidence for this and no biological explanation that supports this idea. Your body maintains a pH of 7.35 to 7.45 and if it goes outside that your enzymes will stop working and you will need to go to hospital. No one has ever been admitted to hospital for this. It simply does not happen.

What's the difference between Megahome and the rest?

Megahome is the original countertop water distiller, other makes like Via Fosa and Make Water Pure are Chinese copies of the Megahome all from one factory in China. H2O distillers are made by Megahome for an American business which sells in the UK and LOOKS as if it is a UK business. The Megahome is made in Taiwan which has manufacturing standards similar to Europe. In addition, Megahome have a UK Repair Centre with a full inventory of parts so if it breaks outside warranty we can still repair it. There is a very good video on youtube which tells you more about the differences between distiller brands https://www.youtube.com/watch?v=xzoZp7J_9gI

Do water distillers need filters? 

Yes. Charcoal filters catch any volatile organic compounds (VOCs) such as pesticides and solvents. Apart from removing these nasty chemicals, the charcoal filtration also makes the water taste better, sometimes you can improve the taste by doubling up on charcoal filters.

How often should you change the charcoal filter?

The filter is designed to be used for four weeks at one distillation a day. If you are doing two a day then change it every two weeks. If you are doing one distillation every two days change it every eight weeks. 

Is the distiller completely free Of BPA?

The standard plastic collecting jug is BPA-free polypropylene. However, if you prefer a glass jug, this is available for a small additional cost. Most people get the glass jug option.

My water has a strong metallic taste?

We get about two people a year with this problem. When it has happened in the past we have tested the distiller and tested the water and been unable to detect any metallic taste or find any chemicals in the water. Metallic taste is associated with a number of medical conditions. Commonly we find it can be associated with Vitamin C over-supplementation.

Does distilled water become acidic?

Distilled water is slightly acidic because carbon dioxide from the atmosphere is dissolved into the water, resulting in a very dilute solution of carbonic acid. However, this miniscule amount of acidity is easily dealt with by your digestive system and will not affect any bodily functions. 

Does distilled water taste funny? 

Distilled water can take up to 7-10 days to adjust to. A good way to think about it is what you are actually tasting is a bit like a negative of the tap water you used to drink. Most people find it tastes sweet and clean and are used to it within 2-3 days. If you have problems, try refrigerating it, add a slice of lemon or try a mineral supplement like Formula 56.

Does the water touch any plastic or aluminium?

All Megahome Water Distillers use a stainless steel tube in the condenser head and, in the glass bottle version, the carbon filter housing is lined with glass.

Can you use the water distiller for alcohol or vice versa?

Not recommended. The alcohol distiller has a less powerful heating element and takes about 12 hours to distill a full load of water. The water distiller runs a bit too quick for alcohol distillation. Despite us saying this repeatedly, some people still buy one machine hoping it will do both, usually a week before they realise we were actually telling them the truth.

Should we replace minerals?

Distilled water does lack minerals, but your body gets minerals from food. Most of the minerals in tap water or mineral water are ones we generally have too much of anyway. If you do still want to add minerals then a supplement like Formula 56 is recommended, it is designed for distilled water.

Do you cook with distilled water?

Some people do, personally we tend to only cook with distilled water when the dish contains water, eg soup. With vegetables we tend to use tap water.

How often should you clean your water distiller?

After each distillation give the boiling vessel a quick clean with a non-stick, non-scratch cleaner sponge. Use the cleaning crystals every 1-2 weeks when you get a scale build-up. People in soft water areas will not need to clean so often.

Can you drink distilled water?

Absolutely, there are no harmful effects associated with drinking distilled water.

Is distilled water good for you?

There is an awful lot of information about the benefits of drinking distilled water available on the Internet. Personally, we drink distilled water because we don't want to drink/ingest the awful chemicals that get left behind in the distiller after each distillation.

I’ve read bad things about drinking distilled water on the internet, What’s the truth?

There are a lot of myths flying around. If you are worried read this article: Nine Myths about Drinking Distilled Water (and why they are complete twaddle).

Does distilled water give you clear skin?

Some people say that distilled water has given them clearer skin however there are no scientific studies linking drinking distilled water with clear skin.

Is distilled water safe to drink?

Humans evolved drinking rainwater and rain is, after all, distilled water. There are no recorded harmful effects.

Is distilled water organic or inorganic?

Distilled water is simply pure H2O, organic chemicals contain at least one carbon atom, therefore water, distilled or otherwise, is technically inorganic.

Are there any side effects to drinking distilled water?

There are no reported side effects to drinking distilled water.

What is distilled water used for?

Distilled water has many uses. It is used for drinking, in cosmetic products, in coolant systems for automobiles, in chemical tests and experiments, to clean medical tools and for canning fruits and veg. Distilled water also is widely used by brewing companies who make beer beverages.

What's the difference between distilled water and filtered water?

Distillation is the only process by which you can achieve absolutely pure water. During distillation, water is boiled to produce steam, which is then collected as distilled water and all contaminants are boiled out of the water.  The steam that comes off is absolutely pure water vapour. 

Filtered water undergoes a basic filtration process and is often treated with chemicals to ensure that it meets the safety standards set out by the U.S. Environmental Protection Agency.

Distilled water vs alkaline water

Distilled water is the purest form of water and the easiest for your body to assimilate. 
Alkaline water has a higher pH level than tap water. Some people claim that drinking alkaline water can help prevent disease, such as cancer and heart disease. However, there isn't enough research to verify these claims and there is no evidence that alkaline water is better than tap water. There are suggestions of potential risks from alkaline water. In a study where rat pups were given alkaline water showed impaired growth and damage to cardiac muscle. A case report released in 2015 said that when a municipal water plant in a town in Germany accidentally increased the water’s pH to 12, skin burns ensued. 

Can I make distilled water at home?

Yes you can, using one of our quality water distillers. 

Is reverse osmosis water the same as distilled water? 

The water distillation process is much more effective that reverse osmosis as water distillation leaves your water 99.99% pure. The added charcoal filter included with the Megahome Water Distiller improves water purity further. Water distillation is also a much easier process.


What is the chemical formula for distilled water?

Distilled water is as close as we can easily get to water with no other chemicals in it. Distilled water is pure water, H2O therefore it has a neutral pH of 7.0.

What are benefits of drinking distilled water?

  • It is considered to be the purest type of water.
  • It effectively removes dangerous toxins from your system. 
  • It prevents from water borne diseases. Some species of parasites and bacteria start their life cycle with human ingestion. Drinking distilled water is your best bet at not catching these diseases.
  • Drinking distilled water protects your family from various chemicals including pesticides, nitrates, fertiliser and contamination from your copper or lead pipes.
  • Tap water contains fluoride. Too much of it leads to fluorosis, which leaves a brown staining effect on young teeth.
  • Cheaper than bottled water - a typical distiller costs approximately 30p for four litres of water, equating to 8p per litre. 
  • Prevents kidney stones. 
  • It is better than spring water which contains contaminants such as coliform, arsenic and phthalates, which can be dangerous for your health. Spring water comprises most of the same impurities found in well water or even tap water.
