Methanol economy advantages compared to a hydrogen economy: 1  Efficient energy storage by volume, as compared with compressed hydrogen. 2  A liquid hydrogen infrastructure would be prohibitively expensive. 3  Can be blended with gasoline (for example in M85, a mixture containing 85% methanol and 15% gasoline). 4  User friendly.
Two things contribute to air pollution that can cause an air quality alert: 1  Ground-Level Ozone â High-levels of ground-level ozone are frequently the cause of air quality alerts. 2  Particulate Matter â Particulate matter consists of pollutants such as dust, soot, ash and wood smoke.
The relative humidity for an indoor environment should remain at most 60 percent; however, 50 or lower is ideal, according to HVAClean. Humidity levels higher than 60 cause mold to grow inside air ducts.Mold growth potentially leads to respiratory problems and allergies. Running a thermostat constantly in the On position is hard on cooling units. Freon gas cools the evaporator, but with a consistent flow of air the coils are unable to stay cool.umidity levels higher than 60 cause mold to grow inside air ducts.
