Does the RO filter out microplastics?

The filter in the Ultimate and Echo H2 ranges between .1 and .01 microns, and the Echo RO is .0001 microns. These are both smaller than microplastics. 

Large Microplastics (1 mm to 5 mm): These can be filtered with mesh screens or filters with a pore size of around 1 millimeter or less. Due to their larger size, they are easier to capture.

Small Microplastics (10 microns to 1 mm): Filters with pore sizes around 0.1 to 1 millimeter are generally effective in capturing these smaller particles.

Microbeads and Nanoplastics (< 10 microns): These are the smallest categories of microplastics and require more specialized filtration techniques. Filters for these sizes typically need pore sizes of less than 10 microns, often down to 1 micron or even smaller to ensure effective capture.
