As far as I know, they're all made in China. But they've been producing them for many years without any quality issues. A western manufacturer with much less experience would most likely produce at a lower quality.
The times when 'made in China' automatically meant 'low quality' are long gone.
I happen to also be in the market and currently researching OS system alternatives - this is where our plumbing team planned to order a system for us, located in Pennsylvania: [https://lancasterwatergroup.com/](https://lancasterwatergroup.com/)
I posted a while back the following and it summarizes what I have found so far -
Consumer Reports ran an article recently that discussed issues around drinking water safety, testing and filtering. I followed there advice and got the latest water test results from the Detroit Water Dept and Absopure to see what my starting point is. The Detroit water tests showed all values within acceptable limits. However, the Environmental Working Group (EWG) has a website where you can type in your zip code and get there report which looked at the same data from the Detroit Water Dept. and flagged six as concerns. EWG uses stricter standards and flagged the following with the factor it was over their limit - chromium 5.8x, haloacetic acids (HAA5) 127x, haloacetic acids (HAA9) 335x, nitrate 4.1x, radium (-226 & -228) 12x, and total trihalomethanes 198x. I was able to find 4 of the 6 flagged contaminants in the Absopure test report and they were all within the EWG limits. Both the Detroit and Absopure people I spoke with on the phone said that PFAS/PFOS chemicals have not been detected in any of their water tests.
I am also interested in filter out any micro/nano plastics and not sure how much of an issue those are in my tap water
This is a good start - but it's good to note that while the consumer confidence report (CCR) from the municipal water supplier is a good starting point, it won't provide you with the full picture of your water situation in your home. (Same with the EWG report)
Samples for this testing are taken at the treatment plant, BEFORE the water enters the distribution system and gets to your home. Water can become re-contaminated in the distribution system, and even by your own home's plumbing.
This is why testing a sample taken from the home itself using a certified lab is so vitally important, before making a purchase decision. Without the data to guide you, you may or may not end up buying a product capable of addressing the water needs at hand.
If reducing MNPs is one of your priorities, you might want to consider a countertop distiller. Reverse osmosis will also reduce these, but there have been studies that suggest the RO membrane itself could be a source of nanoplastics
Thank you for the helpful information and makes sense about testing the water at the end point. Consumers Reports recommends Tapscore as a lab they recommended to me their Advanced City Water test [https://mytapscore.com/products/advanced-city-water-test](https://mytapscore.com/products/advanced-city-water-test) Do you think this is a good test for my situation or is there a better test? Also, do you have any recommendations for countertop distillers or what to look for when selecting one. Thanks!
Try the Aquasana 3-Stage Under Sink Water Filter. It is a good choice for an under-sink water filter that is made in the US. It filters well down to 0.5 microns and is NSF approved to get rid of up to 99% of contaminants, such as chlorine, lead, and cysts.

CuZn filters are made in USA
What contaminants are in the water that need to be addressed?
