Engines with an air intake often require an air filter. As they suck in air, they will be exposed to airborne particular matter. Without an air filter, particulate matter like dirt and dust will enter the engine’s combustion chamber.
Over time, exposure to airborne particulate matter such as this can damage the engine. But an air filter will keep particulate matter out of the engine’s combustion chamber so that the engine lasts longer and is better protected against damage. What type of engine air filter should you choose exactly?
#1) Style
You should consider the style when choosing engine air filters. Most engine air filters consist of a pleated paper or paper-like material. Air can flow through them, but they will catch particulate matter. Nonetheless, engine air filters are available in different styles, such as bracket, non-bracket, ring and cylinder.
#2) Capacity
Don’t forget to check the capacity when choosing engine air filters. Capacity is the maximum volume of air that a given filter can support. It’s typically measured in GPM. Engine air filters with a high GPM can support a larger volume of air than those with a low GPM.
#3) Dimensions
Engine air filters are available in different sizes. To ensure a proper fit, you’ll need to choose filers in the right size. Engine air filters, of course, are designed for use with engines. Some air filters are used with interior cabins, whereas others are used with engines. Because they are used with engines, engine air filters require specific dimensions. If an engine air filter is too big or too small, it may not fit on your vehicle’s engine.
#4) Dry vs Wet
Engine air filters can be classified as dry or wet depending on how they work. Dry engine air filters use dry material, such as pleated paper or paper-like material, to remove airborne particulate matter. Wet engine air filters, in comparison, use oil to remove airborne particulate matter. Most airplanes, helicopters and other vehicles use dry engine air filters, but some of them use wet engine air filters, instead.
#5) MERV Rating
You may notice a minimum efficiency reporting value (MERV) rating for engine air filters. It provides insight into a filter’s ability to remove small airborne particulate matter. Both cabin and engine air filters often feature a MERV rating. For a cleaner engine, you should choose a filter with a high MERV rating, such as 11 or higher.
