Pipe burst right above me in my condo and had water leak almost to my doorway. Same equivalent of water leaked into my shower as well as window leading into the living space. Repairs have begun.

I didn’t even know there was a debate. It is pretty easy to determine when chloramine is present and when it is not and in what ratios as BRS shows with the amazing performance of their filters. As was pointed out, anything that makes it past the carbon gets picked up by DI. I may add a third stage of mixed resin.

I have a feeling the “debate” was a bit of a stretch, to promote their (at the time) new filter.
Still, good info :)

So I’m running 1 micron melt blown filters to catch my sediment, is it necessary you think to run the smaller micron pleated filter? Interested in this silica buster can you post a link or details? Thanks, sorry about your water situation I would have gladly donated since I have not had any outage since this all started and they never issued a boil warning for my area...

Here are the exact SKU for my filters for my Spectrapure rodi unit.

I just got water. I hope everyone bled their rodi input line. Even with a water softener and running the water source my rodi comes from for 15 min, the water going through my input line was filthy. Dirty brown. I bled ~ 40g before water was clear.

The smaller the micron the more junk your sediment filters catch. You don’t need the zetazorb, I just like the extra function. You can just stick in two different sediments with different microns, the smaller the micron the better. Sediments are the cheapest filters to replace, which is also why I replace those most frequent. If the first one starts turning a little brown I replace with a new one. They’re $7 at brs.

Thanks so much for putting the school of RODI into session @mittens 🤓 I can’t wait to implement some of that.

So, do you regularly use the 0.35 micron pleated sf or the $7 BRS one? Planning on revamping my system and the info you shared is very helpful :)

I use Spectrapure filters for my Spectrapure unit and brs on my brs unit lol. Don’t question the logic in that.. I won’t have an answer.

What keep going around in my mind is that the TDS in the water column are not presented in uniform size distribution. If we look and say 1μ particles make up 50% of the total TDS 30% of TDS are 0.5μ and the rest are 0.2μ or below. now we put in a .0.35μ filter as the primary stage, it will get start doing its thing the problem however, is that 1μ particles are filling and clogging the filter pores reducing the efficacy of the filter. A 1μ filter as the primary filter can get rid of 50% of TDS leaving downline filters to retain their effectiveness much longer. in other words, i have a feeling that .035μ is way to small as a primary. in a setup as elaborate as your, I would consider 1 additional "pre" filter cartridge to start with 1 - .05μ

Yup we do the same thing in industrial applications 10 micron 5 micron 1 micro 1 micro absolute. That’s as small as we go though. The melt blown filters we use are far cheaper than pleated or spiral wound filters so that’s what we use.

I’m curious to just put in two of the $7 brs ones. I can compare incoming TDS at carbon block stage to see if the fancy sediments really are worth the $.

At some point you probably have to think about applying pressure with some of those really small µ cartridges.

I start off with either 10,5,1,DI or 5,5,1, DI before the membrane in the 5th stage.
I’ve never checked the water after each stage. I only have a meter before DI and after.

same here.

I usually run a 1µ sediment -> two chlor buster cartridges -> pump->ro->cation->mixed bed->mixed bed

I would like to add a 5µ in front of the 1µ sediment filter.

i start with 1 micron and then .5 the rest of the way

the chlor buster cartridges are resin cartridges (cation) no? are they cheaper than DI? i run DI A and DI B now adding mixed bed chlorine insurance as a final stage based on this convo.
