The new air filtration system in the 2022 RAM 1500 models is the ultimate air purifier you'll need for your truck! It cleans out 95% of impurities from the cabin, including smoke, dust, and aerosols. The RAM trucks have two primary filters for air purification. The first one is the engine air filter that removes impurities from the engine. Second is the cabin air filter that uses the path of the ventilation system to transport impurities out of the cabin. If you have been on the road for a long time, you can start feeling the thickness in the air. It can make all passengers feel disgusted and find peace in the fresh air outside the windows. The only problem is windows not only let in fresh air but also bring various annoying noises from outside, making your trip more uncomfortable. Prioritizing the comfort of users, the 2022 RAM 1500 models were created with an air filtration system that takes 95% of the impurities out of the cabin and leaves only fresh air inside. The original air filtration system will last longer if the continued use does not damage any part. We are available to provide more information about the 2022 RAM 1500's air filtration system.
