HEPA, or High-Efficiency Particle Arrestor, filters trap airborne particles as tiny as 0.3 micrometers in diameter. As air purification systems draw inwards, these filters eliminate any pollutants and contaminates before the machine recirculates the air.
In good condition, HEPA filters can remove 99.97% of airborne particles from an environment. For people with respiratory sensitivities like allergies or asthma, purified air can dramatically decrease their daily symptoms. Even for ordinarily symptom-free people, indoor spaces contain an array of harmful contaminants and pollutants that HEPA filters take care of.
Commercial versus Residential HEPA Applications
Over time, HEPA filters lose their efficacy. In commercial settings, the standard timeframe for replacing a filter is six months. Within homes, some HEPA filters will last up two years. It depends entirely on usage. For instance, filters in portable air purifiers and vacuums—appliances not used daily—get more mileage than those in purification systems connected directly to the HVAC system.
What Happens If You Do Not Replace Your HEPA Filters?
Failing to replace HEPA filters will result in decreased suction power. When filled with too many particles, air cannot pass through the appliance as easily. Consequently, more pollutants will escape back into the environment and the hardware will get overworked. Neglect for too long can even cause the fan to breakdown.
