We do not offer whole house reverse osmosis as it is hugely expensive to install and maintain, it is also very wasteful to use RO water for toilets, laundry and shower, because several gallons of water are wasted for every gallon purified.
Instead we recommend reverse osmosis for drinking water, and whole house filtration and/or softening.
First question - are you on city water or do you have a private well on your property? If you have a private well, please send us a copy of your most recent water analysis or get use our well water test so we can make a recommendation based upon the contaminants you actually have in your well.
Please send your water report to Support@AdvancedWaterFilters.com or FAX 480-348-0235
