My brother Michael have an apartment and he enjoyed the stay there. Mom and Dad suggested to him why not stay at home to save his spending as he pays for the rent and the electric bill. He just simply smile and told to them,despite of the cost he managed to save his money wisely, he has low electric bill but I would say the quality of indoor air in his apartment is good. What he is doing to maximize his indoor air quality is he is using an electrostatic air filter for his humidifier. So, how this electrostatic air filter can boost the indoor air quality in our home?
