Indoor air plants

Most people believe that air pollution is an outdoor problem, and chemicals and other pollutants don't affect them if they are indoors. But the truth is, the air in our offices and homes is more polluted than outside air. The air inside the office or home may contain lead, carbon, formaldehyde, and radon.

Most of these pollutants enter our homes when we buy new furniture or mattress, or when a coat of paint is applied on the wall. The air inside the homes and offices also contain dust mites and other major allergens. People who suffer from asthma, elderly, and children can suffer from health problems because of these allergens. Since most modern homes are airtight, these pollutants cannot easily escape.

Did you know that the average person spends over 90 percent of their daily time indoors? That means that this time indoors could be the reason why so many people suffer from sicknesses and other allergies. And that’s why I think the air that we breathe in our homes needs to be fresh and clean or it can have an adverse effect on the members of the family.

But you know what; you don’t have to worry anymore, because nature is there to take care of us. There are numerous plants which we can use to improve indoor air quality. I have mentioned around 16 such plants that will help in improving air quality:
