The requirement for new buildings and the ongoing maintenance of existing structures pushes the size of the HVAC (heating, ventilation, and air conditioning) business in the United States. HVAC systems are necessary for almost every home or office to remain comfortable, regardless of the outside weather. Air filtration, which keeps the air pure, is a crucial element of these systems. Indoor air quality can be greatly enhanced by using high MERV-rated air filters, such as MERV 13, which are particularly efficient at eliminating allergens from reaching homes and workplaces.
