Air Purification VS Whole House Filtration

PublishTime: 2020-08-05 20:01:50

There are several ways to fight indoor air pollution and to create a cleaner indoor breathing environment. Two great ways to do this are whole house filtration and room air purification. Whole house filtration involves attaching a filter to the HVAC system and filtering air that flows through the HVAC system. Though this is a great way to keep cleaner air flowing throughout the house, the biggest setback is that it only purifies air flowing through the system. Whole house filtration is generally a great way to filter air; however, depending on your air system, this may provide little to no relief.Room air purification is different in that it filters air just in one room space. Air purifiers work by drawing air from a room, pulling it through a filter that removes particulates, and circulating clean air back throughout the room. Air purifiers are great for rooms like bedrooms, offices, classrooms, living rooms, or other rooms in which you spend a large amount of time. They are especially good for young children, elderly people, and for those who suffer from breathing problems like allergies or asthma. The only setback is that an air purifier is only efficient for cleaning one room, and it can be expensive to keep an air purifier in each room.

Improves indoor air quality

Concentrates clean air in one room space

Great for those suffering from allergies, asthma, or other breathing problems

Relatively cheaper filter replacement costs (as compared to whole house filters)

Available with highly efficient filters like HEPA and carbon filtration

How They Work

Air purifiers are designed to draw polluted air from the room. Air passes through a filter, or a series of filters, which traps harmful pollutants. Most air purifiers remove allergens like dust, pollen, pet dander, and mold spores. As these pollutants are removed from the air, a fan sends the clean air back throughout the room. The clean air delivery rate (CADR) really depends on the model. Some air purifiers do a fair job of cleaning the air, while others deliver high quality air purification; it just depends on the brand and the air purification that you are seeking.An air purifier’s filter is the key ingredient to high quality air purification. The filter traps the pollutants, and it is the key factor that determines the purity of the air flowing back throughout the room. Without a good filter, an air purifier is useless. It is also important to keep the filters replaced regularly. As a filter traps more pollutants, it becomes clogged, inefficient, and eventually useless. Therefore, it is necessary to keep your filters replaced as regularly as possible.
