So I have the opportunity to get an iSpring RO/DI system from them for $50. I was wondering if it is worth it or if I should splurge on a BRS RO/DI filter. Also if I do go for BRS, I’m think to get a 4 stage. Would that be enough or should I get a 5 stage. Also should I get plus or regular version. Keep in mind I don’t want to install this permanently because I’m in college and want to take it home when I’m done.
