What is AC Filters?
An AC filter is a fundamental component of an air conditioning system, serving as the crucial initial barrier for air entering the unit.
Based on how it functions within the system, the AC filter acts as the first point of contact for the air that enters an air conditioning unit. Its primary purpose is protective; it acts as a protection layer for the inside of the unit against unwanted airborne particles.
What AC Filters Capture
AC filters are designed to capture various contaminants found in the air circulating within a building. These typically include:
- Dust: Fine particles common in indoor environments.
- Hair: Human and pet hair.
- Pet dander: Tiny flakes of skin shed by animals.
- Fibres: Small threads from fabrics and carpets.
- Other general airborne contaminants.
By capturing these elements, the filter prevents them from accumulating on sensitive internal components like cooling coils and blowers.
Why AC Filters are Important
The importance of AC filters extends beyond just being a simple screen.
- Unit Protection: Their core function, as noted, is to protect the inside of the unit from the contaminants mentioned above. This protection prevents clogs and damage to internal parts.
- Maintaining Efficiency: A clean filter allows air to flow freely through the system. When filters become clogged, the unit has to work harder, reducing efficiency and increasing energy consumption.
- Extending Unit Lifespan: By keeping internal components clean and allowing the unit to operate efficiently, the filter contributes significantly to the overall lifespan of the air conditioning system.
- Improving Air Quality: Although the primary purpose from the unit's perspective is protection, a key benefit for occupants is improved indoor air quality, as fewer dust and allergen particles are recirculated.
Maintaining AC Filters
Regular maintenance is key to ensuring the AC filter performs its job effectively. Depending on the filter type and usage, this means either cleaning or replacing the filter on a routine schedule (e.g., monthly or quarterly). A neglected filter will become clogged, hindering airflow and potentially harming the AC unit.
