Recommend a RO/DI system to me

Yeah hadthe order wrong. However I have heard the 75 is more efficient than the 100. Either way I use the Dow filmtec. It's 98%.

One of my friends told me to look for one with a booster pump so it has a 1:1 ratio?

Myka is bang on with getting a handheld TDS meter first to determine your source water TDS. Number two on the list before you commit to buy, especially something with a booster pump, is to get a pressure guage & check your water pressure. You'll want at least 60 psi to have the system work efficiently. If you're on city water, which I assume you are in Winterpeg, check your house for a PRV (Pressure Regulating Valve). This should be located not too far downstream from your main water shut off valve and is designed to protect your home's plumbing from supplier pressure variations/spikes. Most PRVs are adjustable, I have one & tweaked it up to provide just over 80 psi, take my chances with the home plumbing, so far so good. Anyhow, this may save you the extra cost & complexity associated with buying a booster pump.

Oh shoot Brett, I made a booboo, it's the 100 gpd that aren't 98%, you're right. Thanks for pointing it out.

In the end, it doesn't matter what the gpd rating is as long as it is a 98% rejection.
