I have the BRS 5 stage and absolutely love it. I run the two carbon filters, sediment and a single DI
. Keeps my water at 0 tds
for months before a change of filters is needed. A good idea would be to get a TDS
meter if the unit doesnt have one built in, and if I remember correctly it doesnt have one. The five stage is about $179 during a group buy and it has dual tds
meters so you can tell when to replace the filters. The membrane doesnt need changing out for several years so youre good on that front.
In my opinion it's worth the extra $$ for the deluxe model. But thats just my opinion.
