I'm not a fan of horizontal resin canisters, but as long as it's using standard size filters, why not? If it doesn't work because of leak, those standard size filters and membrane can be used again.
I think that setup is for drinking water, ie the top unit. If memory serves, that top unit adds minerals back to the water so when drinking it tastes like something. Just take that out of line and I believe you will be good to go
