you can buy a cleaning spray for the ac fairly everywhere and u only need to spray it at the start of every season(before u first turn it on) let it sit for like 30-40 mins and it will just dry by itself, also for the air filter(the net thing), just take it out and put it in the shower and wash off the dust(and mold if it has any XD) stay healthy bud
I believe the reason T1 performance is better at worlds then the lck. It comes down to exposure. There in huge crowds all the time and can cope with it. Most teams break under the pressure of 20k fans screaming. That or the plot armor has to be real or aura.
