Air conditioner filters are essential components of any HVAC system, as they protect the mechanical components from dust and dirt, while also trapping indoor contaminants such as dust, pet dander, pollen, mold, and fungal spores. The mesh of the filter becomes denser as air passes through it, trapping these materials and not obstructing air flow. If the filter is not changed regularly, air won't be able to pass through as easily and more particles will get through the mesh, impairing indoor air quality. Not only does this improve the air quality inside your home, but it also protects your HVAC system from damage. The EPA recommends that you inspect your air conditioning filter at least every 3 months.
If you live in a dusty area or there are pets or children inside the house, you should consider inspecting the filter every month. A regular inspection will ensure that a clogged filter does not damage the unit. Filters clean the air that flows through the house by reducing pollen, bacteria, dust and pet dander. Air passes through the filter (or filters) and the filter material traps contaminants before they can circulate around the house. These filters also protect the air conditioner coils and the engine from the same contaminants. An air filter picks up dirt and dust over time, so it should be cleaned regularly.
Those with more folds provide better filtration and help prevent dust and other particles from being recirculated in the air. It can be distressing to know that the air you breathe inside your home may be worse than the air outside. A major culprit for the decline in efficiency is a dirty and clogged air filter, as this means that the air conditioner has to work harder to cool your home, consuming more energy as it does. If you or your family have allergies or other respiratory problems, high-efficiency particulate air (HEPA) filters are recommended. Contrary to popular belief that air is cleaned to protect health, HVAC filters are primarily designed to protect the fan in your HVAC system.
All the extra effort your oven puts in to push air through a dirty, clogged filter can cause significantly more wear and tear. Every air conditioner requires a filter with a specific Minimum Efficiency Report Value (MERV) rating. The best MERV rating for your particular HVAC system is one that sufficiently cleans the air in your home without obstructing airflow or forcing the engine. If you reside in communities south of Chicago, you can contact King Heating, Cooling and Plumbing for professional help with air conditioning filters. All the air that heats or cools your home will eventually pass through the air filter of the HVAC system. In most cases, you can't replace a standard filter with a true HEPA filter because the ducts aren't designed to do so.
