Is brita filtered water adequate for the whole grow?

My tap water comes in around 40ppm after running it through the brita pitcher. So far my plants (2 in veg, 1 seedling) are doing great started all 3 at the same time just got a straggler. Will I need to switch to distilled/ro later? Or will it be fine to keep using the filtered throughout?

For after brita...
These are popular units, when you want portable RO.

Nice, I've been looking for something that'll fit my budget(I'm disabled and on a fixed income). So that seems like what I'll go with. Thanks.
