I assume you mean air from those portable air canisters. It has been my experience that I tend to lose more air between rides when I have used a canister that when I have used a pump.
The basic fix is to ALWAYS, ALWAYS, ALWAYS top off air pressure before each ride If you don't have one, you would do well to invest in a quality floor pump with pressure gauge. I like the one with the pressure gauge built into the foot of the unit as opposed to mounted on the pump barrel. If you tip the unit over, you stand a greater chance of damaging the gauge, the higher it is mounted. I also like a two-in one pump head (that is one single pump head that accepts both Rresta and Schreaer valves.) Double pump heads are not bad either, but I would avoid the type where you have to dissasemble the unit to change the type from one to the other.
