or does any one recommand water from super store or walmart?

you cant sit there and say walmasrt is good or cdn tire is good...
It comes down to how the staff are maintaining their filters and this is not subject to store names...so your experience at each location could vary greatly.

Buy a TDS meter, they actually sell them pretty cheap at canadian tire...lol

and just test yourself before you buy.
