You can't go wrong with 3m.ofcourse only if your ac is fine.
so summer came and AC is needed, came across amazon page of some "3M AC filter" for split , some says it works some its put pressure on motor and choke the AC , any exp.?
dont use any filter, it will create load on motor, elec bill jada ayega, amps increase hone se wiring jal skti h, just wash the filter which is installed in ac.
