Home air purifier told you what is HVAC,
It is a common misconception to consider the air filter inside a home’s heating, ventilation and air conditioning system (also known as an HVAC) to be the most affordable and effective way of filtering your air. HVAC filters provide minimal filtration of airbone particles and deliver the air in a dispersed manner at a relatively slow rate. For maximum performance of your home HVAC system and to maintain energy efficiency levels, you should replace your filter at least every three months. HVAC filters come in different MERV ratings. A higher MERV rating means a tighter weave, which removes smaller airborne particles than a filter with a loose weave. However, a higher MERV rating also means the filter creates more resistance to the air flowing through. This can cause more wear on your HVAC’s motor and yield higher energy costs.
