The cost of a whole house RO is prohibitive in most cases and in really not necessary. Your toilet, shower and landscape don't care if its RO or not and you certainly don't want Deionized water in your plumbing as it is extremely agressive and will eat your pipes and fixtures.
I do recommend softened water though for the whole house. It will save on soap for one and greatly extend the life of your plumbing fixtures and appliances by cutting down on scaling and build ups.
A good 90 GPD reef quality RO/DI system starts at around $130 complete. You can add a drinking water kit which includes a small pressure tank and faucet for another $60 or so and with that you can also hook it to things like the water in the refrigerator door, an icemaker etc. I have RO available at my garage laundry sink, at the kitchen sink, in the refrigerator drinking water system and to my icemaker.
I also have RO/DI in an ATO storage container in the garage which is pumped to my sump and display about 35 feet away and I can fill jugs and buckets from it in the garage also for large water changes.
A water softener if you don't have one already and a good reef RO/DI with add on drinking water kit is really all you need, the house doesn't care if its RO or not and its probably best if it isn't. You maye be confusing a "whole house" filter with a RO/DI and they are not the same. A whole house filter is a large sediment and sometimes taste and odor carbon filter, not a RO membrane and deionizing resin filter.

+1 Not only will the DI hurt your plumbing and fixtures the DI will also effect the enamel on your teeth ! Another option is distiller water but honestly not as good. Ms tanks probably has the most useful solution. Running soft water to your RO/DI only makes sense if your on well especially . Good luck
