I am using it ecm 4000 it's so quite/not noisy and good cooler. No other cooler in market match with it's performance in this size. I am also using another cooler it's shape calls tower cooler bought this year. It's also a blower cooler and with pads and my reason to buy it is it fits well in small place.
We had a lahori cooler. We throw it away. It's just a tension. After that never looked on to buy lahori cooler. It's just a rusty thing after some time of buy. It's expensive on running too because those coolers working on two motors and their desi silver winding consume more bill.
There are lots of plastic coolers which work on one motor for fan+pump. Comes with silver and pure copper winding in nonbranded companies and in branded comes with pure copper winding. In non branded it's our choice we buy silver winding or pure copper winding. Pure copper winding coolers are little expensive than silver winding.
My both plastic coolers having copper winding. And runs on single motor for fan+pump.
