RO systems remove microplastics better than other filters alone

Not surprisingly, RO systems are better at removing microplastics than other filters and do so quite efficiently.  (I was even worried the RO might add microplastics, because the membrane itself is plastic, but apparently whatever it adds is dwarfed by what it removes.)

Other research shows that microplastics mainly result from heat, such as heating water in plastic cups.

I'm shocked at how many liberals and leftists are utterly opposed to RO filtration and insist you must drink tap water.

I use RO water for drinking--including icemaking, cooking, and facial cleansing.  I plan to get a chlorine filter for my shower.

I think it's worth it just for removing the chlorine and chlorine byproducts, not to mention mediocre taste, especially after chilling.  My chilled 9ppm RO filtered water tastes wonderfully crisp and everything cooked tastes better.

I noticed fewer issues on my fact when I started using RO water for facial cleansing.

Chlorine is one of the most reactive substances there is, but strangely people regard it as safe in tiny amounts in their drinking water, while sweating even smaller amounts of metals like lead (also removed by RO) which are relatively inert, in water supplies, chocolate, and protein powders.  Not long ago, we were literally drowning in lead, now in close to parts per billion it's become the reason to avoid everything good.

For that matter, microplastics are fairly inert too.

It is true that calcium supplementation is more called for since I would otherwise be getting about 250mg calcium from my water, which is largely lost.  But that would be true anyway, just in slightly smaller amount.  One must add up and determined the additional needed calcium to reach 1000mg or 1200mg for seniors.
