The benefits of a new air filter are immediate: a replacement can increase your MPG by up to 10% and save fuel costs. Cars with dirty filters show a weaker performance in gasoline consumption. Cars must have clean air and fuel to operate optimally. Dirty filters obstruct the critical air flow needed.
Not only your car's performance, but also your pocket, will feel the impact, as more fuel will be needed to reach the same amount of mileage as before. Drivers are estimated to save between 15 and 30 cents per gallon of fuel when their cars have clean filters. It will be more difficult for the engine to adjust power and speed when operating with a dirty air filter. We reviewed the different engine air filters on the market to give you an idea of what the bill will be.
The filtered dirt and debris will become so thick that they will become clogged and prevent air from flowing to the engine. Most auto repair shops will charge labor to replace the air filter, but you can easily save a few extra dollars if you do it yourself. Often, air filters can become clogged with pollen, dust, and other substances that won't be visible even in bright light. It's best to discard the filter (which is cheap) before spending large amounts of money on other potential problems with your vehicle.
Filters clogged with dirt, dust, pet dander and pollen allow those contaminants to enter the house, reducing indoor air quality. According to the Department of Energy, nearly half of your energy bill comes from using your HVAC system, and replacing a dirty filter can help you save up to 15% off that bill. When less air than needed reaches the engine, excess gas will remain, which will build up in the engine or leak through the exhaust pipe. If you're not sure about any of the steps or are having trouble locating the air filter box, always consult your owner's manual for more information.
This filter is also always included in the user manual and regular checks with your mechanic should help you replace it in time. When the optimal combination of air and fuel within the engine cannot be reached, the car's performance will lag. Perform regular maintenance of your car (or do self-service) to ensure that the filter is replaced when necessary and that your fuel economy is optimized. The type of air filter you choose will also affect the price and may affect how you replace filters in the future.
