1 micron vs 5 micron pre-filters
Can someone explain to me what this means?
I'm trying to buy replacement filter cartridges for my RO/DI unit, and there's
1 micron and 5 micron pre-filters. Which one's are better?
Is that the size of the stuff that can pass through? or is that the size of the filter? They're both the same price, so I'm confused.
I have a 4-stage Kent Maximma Hi-S RO/Di unit. It came with 1 micron, but not sure which to get.
