True, this has been my point. I can see why someone might feel like filtered drinking and even shower water but I see no issue with chlorinated water in the toilet and definitely gardening water should not need filtering.

My place is still a new build in the planning stages; in your experience is it likely to be a huge pain in the ass/expense to have the plumber split off the outdoor and/or toilets before the filter? I feel like the pipes feeding the bathrooms would need duplicating for the toilet which is just wasteful.

It's not terribly different to having toilet/outside taps set up with rainwater - you have duplicate pipes from the point of entry to the fixtures. That's pretty common now.

Water pipe is pretty cheap - can't cost more than $1k if do it while the framing is open. Possibly a good return on your money if you consider the cost of cartridges

I believe the carbon block does the same/better job than a gac/kdf in that more water comes in contact with a carbon block than gac

I'd just put the GAC/KDF filter by the filter tap, as opposed to whole house

Yeah, my understanding is that carbon block is better for filtering, but that KDF is good for preventing algae growth.

I don't want to filter the kitchen tap if I already have a whole house system.

We just put one on the kitchen tap. That s more than enough, because, if you want a drink of water, you just go to that tap. Some fridges also have them built into their cool water system, but I have found that you can still taste the chlorine through fridge filter (believe they are usually carbon ones), unlike an under bench filter.

Even with a whole house filter its still a good idea to have a filter at the tap to capture any potential contaminants that get picked up post whole house filter.

We have a 6 stage R/O system in our kitchen, I'll be getting a whole house filter at some point as I'd like to reduce the amount of chlorine our daughter has to bath in

True, and the kitchen tap probably will as it's be one of those multi-tap things.

But not uncommon to fill a glass of water from bathroom tap etc.

We distill our drinking water using a USA-made Waterwise (locally rebranded as Pure Magic). It's the best method but takes time and uses electricity.

We don't bother filtering water used for anything else.

We want it simple, turn on the tap - get good water.

We also want all water filtered (all indoor water any way), not just drinking water.

I can't overstate how horribly strong the chlorine is in the water at our house.

I understand carbon filters largely just improve the taste.But you will likely be consuming other things. I use a distiller, and the yellow water and smell left behind in the chamber isn't good. So I try to mainly drink distilled water only.

I think the whole home filtering is more designed for people using tank water.
