FAQ About Air Filters
what does a cabin air filter do?
Think of the cabin air filter as your car’s first line of defense against the dirty air outside. Every time you turn on the AC or heater, air is pulled in from outside, and that air isn’t always clean. The cabin air filter helps catch dust, leaves, pollen, and even unpleasant smells before they reach you and your passengers.
If it gets too dirty, the airflow becomes weaker, the air might start to smell stale, and your windows could fog up more often. That’s why changing it regularly isn’t just about comfort, it’s about keeping the driving experience clean and healthy, especially for families or people with allergies.
how often to replace cabin air filter?
There’s no fixed rule for every car, but in general, the cabin air filter should be replaced every 12,000 to 15,000 miles, or about once a year.
That said, driving conditions make a big difference. If the vehicle is often used in dusty environments, high-traffic cities, or areas with heavy pollen, it may need to be changed more frequently.
Common signs include reduced airflow from the vents, musty smells when the AC is on, or foggy windows, these are all reminders that the filter might be clogged.
It’s a small part, easy to overlook, but changing it on time really improves the air inside the car and keeps the HVAC system working efficiently.
At GDST, we offer high-quality cabin air filters built for long-lasting performance and reliable protection, perfect for helping your customers breathe easier on the road.
what does an engine air filter do?
The engine air filter keeps dust, dirt, and debris from getting into the engine. It makes sure the engine gets clean air to run properly.
If the filter gets too dirty, the engine can’t breathe well—this can lead to poor performance and higher fuel use.
So, even though it’s a small part, it helps protect the engine and keep the car running smoothly.
how often to change engine air filter?
Usually, it’s best to swap out your engine air filter every 15,000 to 30,000 miles. But honestly, how often you change it depends a lot on where you drive. If you’re often on dusty roads or stuck in traffic jams, the filter will get dirty faster and need replacing sooner.
A clogged filter makes it tougher for your engine to breathe properly, which can slow the car down and use more fuel. So if you notice your car feels less peppy or drinks more gas than before, it’s probably time to check the filter.
We offer reliable engine air filters that fit a wide range of vehicles, help keep engines running smoothly and efficiently.
