Just a side note, I would change both sediment filters to 1 micron, 5 Microns is quite large so it’s unlikely doing much, better to go 1 on the first and anything it misses the 2nd will hopefully catch.

Thanks Reef,
Wouldn’t clog too quickly?
Was thinking 5 to 1
Funneling it if that makes sense

Sorry for the delay on the video. Broke my old phone recently so I’m having trouble getting on to old accounts like YouTube.

This would depend on your source water and your pipes. Two 1 microns won't hurt, or you could even run a 1 followed by a 0.5 I'd you wanted

I have an extra canister I need to mount still, but I'm planning on a 1 micron followed by a 0.35 or possibly 0.2 then 2 of the carbon blocks.

Is the rodi unit hooked directly to the hose bib or to a hose?
It's not hooked to the hose. Theres 'Y' at the hose bib and the hose connected to one while the feed line to the RO/DI is connected to the other. The bib is off unless the hose or the RO are needed. The Y has individual shutoffs for each out.

I use 1 and it's fine...remember the rating is a nominal rating, so a 5 micron only needs to stop size 5 TDS around 60% of the time, (not sure of the exactly standard) that leaves 40% that can be much bigger than 5 microns passing through and it still gets a 5 micron rating.
1 microns for the first will still allow say 5 microns to pass but the 2nd sediment filter has another chance to catch those.

I got the below answer several years ago from an engineer at Spectrapure when quoting out and installing a unit at my work.

The largest micron size we sell and that we recommend is a 1-micron sediment
filter and here is why:

Most people are not aware that these types of filters are "nominally" rated
not "absolute" rated and the percentage of 1 or 5 micron particulates that
will be captured will be different with different manufactures. (Typically,
nominally rated filters will capture only about 5 to 10 % of the
particulates they are rated to capture).

Nominally rated 5 micron filter will capture 10% of the 5 micron particulate
and about 80% of particulates that are > 50 micron. The 1 micron filters we
use typically capture a much higher percentage of 1 to 5 micron
particulates.

just to be clear, the removal of these particulates in no way affects the result obtained by the TDS meter?
