AIR FILTRATION
What’s the outcome?
Breathing problems, respiratory illness, changes in the lung’s defenses, and worsening respiratory
and cardiovascular disease.
Irritation of the eyes, nose and throat. Exposure to high levels may cause
muscle spasms and can damage the lungs and heart.
Irritates the respiratory tract and eyes, causing coughing, burning sensations, wheezing and
shortness of breath. Can decrease lung function and aggravate asthma and other lung diseases.
Can also lead to premature death.
Chronic health effects include cancer, central nervous system disorders, liver and kidney
damage, reproductive disorders, and birth defects.
Irritates the lungs and lowers resistance to respiratory infections such as influenza. Exposure to NO2 is associated with increased deaths from heart and lung disease, and respiratory illness.
Reduces oxygen delivery to the body’s organs (including the heart and brain) and tissues.
Long-term exposure to lower concentrations can cause neurological damage.
Headaches, skin complications, respiratory and mucous membrance irritation, respiratory soft tissue damage and degeneration, confusion,
impairment of verbal recall, and memory loss.
Cardiovascular and lung diseases, heart attacks and arrhythmias. Can cause cancer. May lead
to atherosclerosis, adverse birth outcomes and childhood respiratory disease.

Choosing the right filter is important!
Typically, as particulate removal increases so too does energy demand
Finding the right balance between the two is key!
