Used in heating, ventilation and air conditioning, HVAC filters are generally made of gauze like material. This provides a small passage for air to flow through whilst also stopping larger particles. Standard air filters are designed with efficiency in filtration, as they collect debris and dust. Some more complex filters remove odours and feature a charcoal element. Preventing debris from entering a ventilation, cooling or heating system is vital in ensuring longevity as foreign objects in these types of systems can cause them to overheat and cease functioning.

If these types of filters are not properly attended to, they can become clogged. This can prevent air flow possibly causing the system to overheat and can eventually lead to equipment break down or fires. Changing air filters regularly is vital for health and safety and a HVAC systems longevity.
