Filtering a cold water line going to a fridge

There are plenty of filter options for use with any 1/4" water line. I have one mounted on the wall behind my fridge. Just goes inline of the water supply.

I've been using a GE RO undersink system for about 10 years now. Been getting all my replacement filter cartridges from Purewater4u.

RO systems are good as long as you buy enough 'volume' for your needs in a day.

The 2-3stage filters can provide limitless water. RO's only as much as they can tank.

Some RO's are very wasteful on water...newer ones don't waste much.

RO's also take up quite a bit of usually undersink space so you have to consider that as well.

A good 2-3 stage approaches the quality of an RO system in almost all filtrations.
