Have you done a water test? That is really the first step.

Carbon is good for neutralizing odor. It really depends on your water quality.

Reverse osmosis is the way to go as long as you have good water pressure. Carbon won't remove everything.

Need to test first. Well or City?

I've been looking into options too and if you find something good please post. I'm in the market.

I have RO. Removes everything that carbon won’t like fluoride. For drinking water though you want to add back minerals in some way. Most kits come with a remineralizing filter.

Brita filter ftw

I think it can be great and effective, but efficacy depends on what you’re trying to filter out?

RO to remove hormones and pesticides

Maybe for whole house, but I'd still use RO for drinking/cooking water

Reverse osmosis then remineralization

Also, I found this site useful to see what's in my local supply and which methods can remove it.

Test first. Depending on the results, and what you are tying to filter out, there are several options.

Also consider water hardness.

Also consider whether your water only be filtered for the house, or will also be used in the garden/landscaping.

I use this for whole house

Mainly for showers, brushing teeth. I use a few 2.5” x 9.75” cartridges under sink for cooking and coffee but filters cannot beat fresh spring water, so I have spring water delivered for drinking.

My girlfriend had allergic reaction to water from expensive water filtering system that was softening the water.

Interesting podcast I just listened to on water!

Berkey (carbon) with the additional flouride/arsenic filters is my go-to.

I have a whole home filtration system and it certainly reduces water pressure throughout the home, keep this in mind.
