Do home air purifier work well for air pollution?

To reduce the contaminants that lower air quality in the home, the EPA recommends minimizing or eliminating the sources of the pollution and increasing ventilation in order to replace bad air with good.
Home air purifier helps control the levels of airborne particles including those associated with allergens.
Most air cleaners are being designed to target unhealthy particles floating in the air. Among these particles, the relatively larger ones are often missed by the air cleaner because gravity pulls them to the ground more quickly than smaller particles, keeping them out of the purifier's reach.
