@nicholslg I use a .2 micron filter in my kitchens. It is sufficient to filter out MAC.
Here is how we do it - a "10 inch" two stage under-counter water filter with a 1 micron charcoal filter at the intake end and a .2 micron Blu Technology filter at the output end, a very short vertical tube attaches it to a tap installed next to the kitchen faucet. We replace the filters every 2-3 months. This setup is in our home, winter tiny home, and camper.
