It makes a person wonder how safe our distilled water really is, manufactures of these products have strict procedures that employees have to follow.
I check the expiry date on the bottle always to make sure I'm getting reasonable product.

How does checking an expiry date make sure that the water is OK? Water isn't going to go "bad" over billions of years. Bad quality distilled water is "bad" because it has something dissolved into it at some point in the water supply or packaging process. That means it's "bad" before it even hits the store-shelf. No freshness date is going to help you there!

I remember when nutrition labels were first put on food.
I had to laugh out loud when I saw the nutrition labels on water and ice.

Why do companys put expirey dates on food products, its to make the consumer aware of higher risk of spoilage!Its the law!

I'm not quite sure what you are saying.

"Filtering" doesn't usually remove dissolved solids.

The whole point of reverse osmosis is to remove dissolved solids. They are commonly used to desalinate sea water. There are different types of RO membranes and systems, but they're usually for removing dissolved "salts."

If you want to check your water, get a clean glass container, fill it with your water and boil it dry in the microwave. Once you boil away all the water, check for the level of white residue in the bottom of the glass. Then try it with tap water or other forms of water. Example.

Be careful. Water boiled in the microwave has a tendency to suddenly boil explosively when disturbed, including shortly after turning the microwave. Let the water sit for half a minute or so before opening the door.

Also, boiling the water only shows some of the contaminants, mostly the "dissolved salts."

I wouldn't try that unless I knew how to do it safely. #1. Use Pyrex, not glass!

#2. Water boils violently in a microwave. Disturbing boiled water in a microwave, can result in a flash off of water and steam, resulting in severe burns.

Just use good Steam Distilled Water, $.80 a gallon is cheaper than the emergency room. Jim

Glass in the microwave is not a terrible hazard, other than burning, even with normal glass.

BTW, "Pyrex" is now just a brand name. It's not all borosilicate glass the way some people think. Actually, some "Pyrex" has been non-borosilicate glass for some time, and the proportions have gotten worse since Corning sold off the brand name.

The flashover problem with boiled water can happen with coffee, tea, or even soup, although it seems to be more of a problem the cleaner the water. Heck, even meat can explode suddenly in the microwave, sometimes after you open the door.

However, if you do this, let it sit for half a minute or so before opening the door and messing with it. That applies to any kind of liquid in the microwave.

BTW, I cook stuff in water in glass bowls in the microwave several times a week with only very rare problems. Don't disturb it until it's calmed down for 30 seconds or so and no problem.

The "distilled" water is suggested ONLY to prevent mineral build up.

Yes, that is absolutely true. That said, mineral buildup is an issue especially if you just don't have the time for one more thing.
