Worth knowing
Under-sink RO or whole-house treatment?
They solve different problems. One makes better drinking water. The other protects the plumbing and appliances. Our hard water is why people ask.
Under-sink RO
Filters water at one tap
Where it wins
- Very clean drinking and cooking water
- Removes dissolved solids that basic filters miss
- Fits in the cabinet under the kitchen sink
- Can also feed the fridge ice maker
What to know
- Only treats the tap it is connected to
- Sends some water down the drain as it filters
- Filters and membrane need replacing on a schedule
- Does nothing for scale in heaters, showers or appliances
Whole-house
Softener or filtration at the main line
Where it wins
- Treats every tap, shower and appliance in the house
- Cuts the scale that shortens water heater and fixture life
- Easier on skin, hair and laundry
- Pairs well with an RO tap for drinking water
What to know
- Larger install with a bigger up front cost
- Needs space near where the water enters the house
- Softeners need salt and occasional service
- Softened water alone is not the same as RO drinking water
