Indoor air is 2 to 5 times , even 10 times more polluted than the outside air
We even spend 90% of our time indoors. The air that we breathe in our homes, schools, and offices can put us at risk for health problems. Some pollutants can be chemicals, gases, and living or others.
Because of its serious effects, poor IAQ problem is classified as a top-five environmental health risk by the EPA.
The best way to reduce indoor air pollution is to pay much attention to the below circumstances. Pets like dogs and cats often cause certain smells and even allergies. Some plants like alocasia macrorrhiza should not grow indoors, as it produces harmful liquid. New furniture containing formaldehyde and benzene must have a long time good air ventilation.
Air purification is consisted of active purification and passive purification. Among the passive ones, HEPA ranks first in terms of its superior performance, able to filter or adsorb more than 99.9% of cigarette smoke, particulate matter and common bacteria at one time circulation. Surely it needs to be replaced once shelf time approaches.
Indoor air pollution is often overlooked in the absence of serious air pollution. Inaccurate detection instruments can have relatively serious errors, because measurement unit of air pollutants is microgram, which might mislead inhabitant.
