Abstract This Paper presents the idea to overcome the drawbacks of existing Air Washer used in industries or anywhere. This is fully solar powered air washer which uses blower, pumps nozzle, heating & cooling coil and reservoir. Working fluids are water and air according to applications it can be used. It removes dust and all unwanted particles for cleaning and maintenance purposealsomaintainrequiredand ideal temperature in surrounding environment. Also it is cost efficient and small in size to handle and operate.

CONCLUSION:
Three policy scenarios of energy performance MEPS have beenproposedintermsofSEER(finalenergy=electricity) and EER (final energy = electricity) for the five main categoriesofelectricproducts,onathreeTiersbasis,which comesdownto2015,2017and2019.EERMEPShavebeen introduced to forbid products with a sufficiently high seasonalperformancebutalowfull loadperformancethat could have an impact on the electricity grid at the time of summer electricity peaking demand in warm countries.
