can I ferment fruits and filter it to get pure alcohol?

No. Filtering fermented fruits will not yield 100% alcohol. You would be lucky to achieve 20% and have a drinkable substance.

There is no such thing as pure alcohol really. Even if you buy 200 proof alcohol, it will immediately absorb water from the atmosphere when it is opened, resulting in 190 proof, or 95% alcohol.

You can't filter one liquid from another. Alcohol is soluble in water and no amount of filtration will remove it. To increase the alcohol level above the 20% or so which is the maximum you can produce from fermentation you muist distill.

Distillation is illegal in most countries of the world.

No. After you ferment fruits, you need to distill it to get pure alcohol

You can't filter out the alcohol. You would have to distill it. When you distill it you raise the temperature of the liquid to higher than where alcohol vaporizes--about 174 degrees--and less than the 212 degree boiling point of water and then drain it off as it changes back to liquid.

You can cold distill it, but that increases the concentrations of some bad higher alcohols like methanol. It's how applejack is made at home, and some beers like eisenbock.

Distillation is illegal and dangerous. You can make home sugar wine and get around 12 vol easily. But you have to read at least one month on line in order to avoid botulism. My advice don't try to make any alcohol beverage at home you are just going to hurt yourself.

It's the same as moonshine you have to distill it because with it that you won't get pure aclhol you would be better off just buying it

No, you have to use a still to get pure alcohol.

NO,....alcohol is Distilled

No you wouldn't be able to
