If you lived through this spring in Northern Nevada, you remember the afternoons when the sky over the Truckee Meadows went tan and grit hit the windshield on I-80. Wind is part of the high desert, and dust is part of the wind. Reno gets only about 7.35 inches of precipitation a year at the airport (NOAA 1991-2020 normals), so there is not much keeping the ground in place.
Two filters, two jobs
Your car has two air filters, and they protect different things. The engine air filter sits in a box near the intake and keeps dust out of the cylinders. The cabin air filter usually sits behind the glove box and cleans the air coming through your vents.
Dust affects them differently. A clogged engine filter restricts airflow and, on older engines, can cost some performance and economy. A clogged cabin filter means weaker airflow, a slower defroster and more dust and allergens in the car with you.
Who gets hit hardest
Wind dust finds everybody, but some driving makes it worse.
- Gravel and dirt roads in Lemmon Valley, Golden Valley, Johnson Lane or the Pine Nut foothills
- Construction-zone commutes on the growing edges of Reno and Sparks
- Following trucks and trailers on US-50 and US-95A
- Parking outside under trees in a windstorm, which fills the cowl with debris
What the intervals say
The Car Care Council suggests checking the engine filter at every oil change and replacing the cabin filter about every 12,000 to 15,000 miles, sooner in dust (Car Care Council). Most owner's manuals give an engine filter interval with a shorter one for dusty conditions. High-desert driving often qualifies.
That is why we check the engine filter during the maintenance check on every full-service oil change, and the cabin filter on request. You see it, and you decide.
Carson City and Minden get a bit more moisture than Reno, about 9.34 inches a year (NOAA), but the Carson Valley has its own wind and its own dirt roads, and the valley floor around Gardnerville is farm country with plenty of loose soil. Nobody in the region is exempt from dust, only from how much.
Why early summer is the right time
The windy months set up the next two seasons. Summer brings A/C season, when a clogged cabin filter makes the system work harder for less cold air. Late summer often brings wildfire smoke, when a fresh cabin filter is the cheapest air cleaner you can buy for the car. Swapping a dust-loaded filter now gives you a clean one for both.
Gene P. wrote that the Gardnerville crew changed his air filter as part of a top quality oil change and covered all the bases within the scope of their services (Google review). Any of our four service centers can do the same, no appointment. If your last filter was before the windy season, bring the car in and take a look.
