AskPatty’s Tips to #Green Your Car and Save Gas: Keep Your Air Filter Clean - Switch to a Reusable Air Filter
Replacing a clogged air filter can improve your fuel economy by as much as 10%
As long as you’re switching out your air filter, a reusable air filter is a good way to reduce waste, especially when you consider both the filter and packaging are discarded. While some things -- like paper towels, toilet paper, and tissues -- are better off being disposable, some consider it an investment in their car to purchase a high-quality reusable air filter.
According to K&N Air Filters, some can go 50,000 to 100,000 miles between cleaning, depending on driving conditions. Like a re-usable coffee filter, these do cost a little more up front, but depending on how long you drive with it, can save you money over the long haul. Important tip here: make sure your reusable air filter is completely dry before reinstalling to prevent it from collecting bacteria and fungus.
