It's a good idea to replace your cabin air filter every 15,000 miles, according to most automotive industry experts. However, the exact mileage may vary depending on the manufacturer's recommendations and your driving habits. If you're not sure if it's time to replace your cabin air filter, you may notice some warning signs, such as reduced airflow through your vehicle's HVAC system or persistent foul odors. When you look at one of these, it's a good indication that it's time to replace the cabin air filter.
Whether you notice these signs or not, you should have your cabin air filter checked every 15,000 to 25,000 miles or at least once a year. When the filter starts to clog with debris, it can start to affect the air quality inside the cabin. The best indicator that the cabin air filter needs to be changed is by visual inspection, observing the impact of the air flow, or by smell inspection. We'll talk about this in another article, but even for the most basic hobbyists, replacing the cabin air filter is something anyone can do at home. The cabin air filter not only protects you from allergic reactions, but also from other airborne contaminants that can cause very serious health problems. That's why replacing a clogged cabin filter frequently is essential, because when you don't, you'll end up breathing in all the nasty debris trapped in the filter.
Although 76% of vehicles in circulation today are equipped with a cabin air filter, most vehicle owners are unaware of their cabin air filter, which is specifically designed to clean the air entering the interior of their vehicle. Cabin air filters are among the items that are supposed to be replaced regularly as part of a comprehensive maintenance program, but this simple part is often forgotten behind other larger maintenance items, such as oil changes and fluid changes. Some premium cabin air filters such as PUREFLOW with four-stage filtration technology are specifically designed to trap 99 percent of mold, pollen, dust, harmful gases, bad odors and also inactivate viruses and bacteria. This is because when the air inside the cab is dirty, the air conditioning unit has to work even harder while the engine burns out. You should also note that if you pay to replace the filter, this cost increases considerably due to the fees charged by most dealerships and service stations. Typically, a cabin air filter is located just behind the glove box, just under the hood, or under the dashboard on most modern vehicles.
Another challenging environment in which millions of people find themselves is heavy urban situations, where air quality is extremely poor due to the large volume of vehicles on the road and a large amount of dust and dirt that rises as a result.
