Ventilation System VS Air Purifier

Posted by admin on November 11, 2014 in Air Purification with No Comments

Ventilation systems and Air purifiers are so common in our everyday lives. Ventilation systems change air flow in any space in order to provide high indoor quality. However, air purifiers refresh the air by eliminating allergens, mold, pollen, dust, etc. People always ask if air purifiers are needed when there is a ventilation system in house.

I want to clarify this question. First of all, small air purifiers units are used for residential and commercial spaces. They can be used in a kitchen, living room, or bedroom to purify indoor air by removing air contaminants. Air purifiers are good choices for households, apartments, pet stores, smoke stores, and small medical clinics.  On the other hand, ventilation systems are designed  for large buildings such as supermarkets, apartment buildings, churches, hospitals, office buildings, etc. The ventilation system replaces indoor air with outdoor air routinely and can control humidity of indoor air.

Secondly,  air purifiers are built to refresh indoor air by eliminating mold, pollen, and pet dander. Air purifiers ionize those air contaminants and even produce ozone to kill odors, bacteria. However, neither ion nor ozone is released through ventilating process. Ventilation system circulates indoor air, maintains the indoor’s temperature, humidity, and also increases the energy needed for heating and cooling.

In summary, ventilation system doesn’t conflict with air purifier. They both have their advantages for different areas, ventilation system works better for large buildings compared to air purifiers. Air purifier may focus on removing dust,bacteria better than ventilation system.
