Having fresh air and a comfortable indoor environment is very important to keep your loved ones healthy and fit. Air filters play an important role in maintaining indoor air quality since they very efficiently remove all the airborne particles present indoors. Air filters are part of the HVAC system and are helpful in trapping dirt, dust, allergens, pollen, and other airborne particles. Whether it is in a commercial, industrial, or residential environment, air filters ensure that the air traveling through is breathable and clean.
In addition to this, air filters not only enhance the quality of the air but also protect your HVAC equipment from the collection of dust and debris; as a result, the life of your air filter is extended. Air filters are available in standard and custom sizes in HVAC systems. Standard filters come in a range of sizes and filtering capacities and are commonly used in many different environments. On the other hand, customized filters offer greater flexibility and efficiency because they are created on demand to satisfy particular requirements or are made to fit into particular systems.
Standard Air Filters
Standard size air filters are the per sized air filters that are available in the market, and these are commonly used in residential and commercial HVAC systems. These filters are specially designed to fit into the majority of the HVAC systems since they can be easily fitted into the slots of the HVAC system. These filters are easy to replace, as you do not need any specific measurement or dimension. The most common standard sizes for HVAC systems include dimensions like 16x20x1, 20x20x1, 16x25x1, and 20x25x1, where these numbers are used to depict the length, width, and depth of the air filter.
Air filters are measured in inches. Standard size air filters are made up of different materials, such as fiberglass, pleated, and HEPA, and the ratings of the filters also differ, such as the MERV rating, MPR rating, and FPR rating. Each of these is done to satisfy specific filtering needs, ranging from basic dust and allergy removal to more advanced particle removal. These filters are important for keeping the indoor area clean and ensuring the HVAC system performs properly.
