Do water filters remove microplastics from tap water?

Distilled is the way to go. I recommend the stainless steel unit CO-Z. I have 2 and the cost is around $90. I distill a gallon every 2 days. It may be a little more work but if you use the food grade citric acid with a brush the disgusting stuff left behind on the bottom comes right off. If you unplug it a few minutes early you don't even need to do that cleaning. I have been using countertop distillers since 1990 when Sears first introduced them. They do remove minerals as well so you need to get them elsewhere. They last for years.

When we swallow some daily vitamin supplements are we ingesting more micro plastics from their plastic casings?

Do you have any information on whether faucet filters work as well as pitcher filters? I'm thinking of switching from PUR pitcher to their attachable faucet filter.

Many get water from an in store R.O. water machine which should get everything out. We also reuse the plastic jugs over and over. Please test this process as it is used by many.

and oddly, both of these company's filters then filter the water into a... wait for it... plastic pitcher.

I own a countertop model water distiller. Bought it in 1995 while training for marathons (one drinks a LOT of water during such training), has worked flawlessly for me ever since - thousands of gallons have been purified in that machine.

But now I wonder... do microplastic particles evaporate with the steam? and if so, will they be caught in the carbon after-filter?

The Aquasana Clean Water Machine website says that it filters out particles above .5 microns.

Aquasana Clean Water Machine, which I bought because water filtered by PUR filter had funny taste to me, is a powered countertop filter, meaning you plug it in and it forces water through a filter which is supposed to get better filtration than "passive" filters.. It is certified to meet both ANSI Standards that PUR meets plus the new standard (401 I think) for removing drugs thrown away into water sytsems that get into drinking water. I a going to look up the micron level for particulates.It does seem to me to be the best countertop filter I have had..

FYI: Berkey responded
" The microplastics have not been tested for so we are not able to say if they are removed or reduced or not, however the pore structure size of the microplastics are around 10 and the Berkey filters pore structure will trap anything larger than a 2 so they are more than likely being removed but we can't say for sure. Below is a list of all of the contaminants that have been tested for and what is removed and reduced and to what level. If you have any more questions please let us know."

How well would a more expensive above-counter filter, such as the Berkey, filter out these particles?

I recommend a reverse osmosis unit for many health reasons yet the neatest is that over time a gallon of R/O filtered tap water costs about $0.10/gal. I use a glass 3L jug to store the water avoiding plastic bottles.
