Either is fine but distilled water is usually easier to get hold of. Look for one that states less than 1 ppm dissolved solids on the label.
Using demineralized water in your sleep apnea machine is not recommended as it may cause mineral build-up in the machine's components. Distilled water is the best choice to prevent mineral deposits and ensure optimal functioning of the device.
Purified water can be used in a battery, but distilled water is generally the preferred choice. Distilled water is free of minerals and impurities that could potentially affect battery performance or longevity. Using purified water that still contains some minerals may lead to corrosion or reduced efficiency in the battery over time. If distilled water is not available, purified water can be a temporary substitute, but it's best to use distilled water when possible.
Mineral water is not recommended for use in batteries as its impurities and minerals can interfere with the battery's chemistry and performance. It is best to use distilled water, which is free of impurities and minerals, to ensure the proper functioning of the battery.
The best water to use in a car battery is distilled water. Bottled water can be used in a pinch however there is a possibility of damaging a cell. Rule of thumb would be to always use distilled water unless you absolutely have no other choice.
I think, the best way to check water is the use of a hydrometer. Pure (distilled) water has a Specific Gravity (SG) of 1.000. So check it with a hydrometer, if it's SG is one than it is distilled water otherwise contaminated.
No, water from tumble dryers is not suitable for use in an iron. The water used in irons should be clean and free of any potential contaminants or residues that can damage the iron and affect its performance. It is best to use distilled or demineralized water in irons to prevent mineral buildup and clogging.
Best to keep the battery in the house. Make sure water level is topped up, use only demineralized water, and just use a 2 amp charger. Once a month for a couple of days is good.
Interesting question that I too was looking for... We really should use distilled water... because unlike the distillation process, the demineralisazation process will not likely trap other impurities such as bacteria... just minerals. For most uses this would not be a problem, such as putting into your clothes iron. So theoretically you could have 100% mineral free water, but also with bacteria. I imagine that the H202 would take care of this, since that's the purpose we're taking the hydrogen peroxide for, right? I just bought some demineralized water today from a gas station, and after having done some research, I decided I'd better wait until I can get some distilled water. Here in Brazil the water will no doubt be full of all kinds of stuff... but I guess it depends on the source of the water that was being demineralized. Your call.
We've got to point out that there isn't a ton of difference - at least not in the finished product. But let's look at what differences there are. Perhaps the obvious difference between demineralized water and distilled water is the method of purification. Demineralized water is water run through a resin bed to pull out the "junk" and deliver clean end product. Distilled water is "boiled off" and the vapor cooled to condense and recover a nearly pure product. Resin beds can range from "really good" to "super good" to increase the purity of the water, and distillation can be repeated (double distilled) to improve the finished product. Some things are going to "sneak through" the distillation process, but not many. This is arguably the "best" way to get the purest water from the general laboratory support facility. Resin bed processing will remove ionic products, but will let though some dissolved materials which are uncharged - like many organic compounds. Living microorganisms can also get through because the resin cannot "stop" them unless it mechanically traps them. To kick the demineralizers up a notch, we can use more sophisticated (and more expensive) resins and better filtration. Consideration should be given to the use of the water and how much "contamination" can be tolerated. Distillation leaves behind in the evaporator concentrations of all the "junk" that is being removed from the water. Buildup of scale is problem. Maintenance considerations aside, energy costs, even in a vacuum still, can be considerable for larger quantities of water. Resin costs money, too, so renewing the beds is something that must be budgeted for. The lab manager will consult with the laboratory supervisor to determine which method provides the best value for their application while maintaining quality that will not compromise the work.

Make sure the distilled water is at the right levels in the cells and trickle charge with a mains battery charger for 12 hours every week.
Pure distilled water.
Among distilled, mineral, and top water, it is usually safe to drink them off. Distilled water is the best option as it has had all contaminates removed and is pure water.
