Forced air flow-through air purifiers are definitely more effective than the previous two types of air purifiers mentioned; electrostatic air purifiers and electric spark air purifiers. However, unfortunately the filters used by these systems are fairly ineffective on the majority of harmful particles and most viruses & bacteria. Plus whilst forced air flow-through air purifiers usually have fans built-in, they are more often than not far too weak to move a decent amount of air efficiently meaning low air exchanges per hour and rendering the forced air flow-through air purifier unit ineffective at purifying the air of an averaged sized home.
