That filter's catching road dust, pollen, brake dust, and exhaust soot from the car in front of you. Once it fills up, you'll notice. The fan has to work harder to move less air, the A\/C feels weaker on the highest setting, and there's a musty smell when you first turn it on. Most people don't think about this filter until it's long overdue, and then they're surprised how much better the car's air feels after a fresh one goes in.\u003c\/p\u003e\n\u003cp\u003eHKS's Nano filter drops in exactly where the factory filter goes and catches finer particles than a basic paper filter. It's not a horsepower part. You won't feel anything driving the car. What you'll notice is cleaner air, less dust on the dash, and fewer allergy flare-ups in spring. If you drive in traffic or a city, or anyone in your car has allergies, it's a worthwhile upgrade at the next filter change.\u003c\/p\u003e\n\u003ch4\u003eNanofiber Filter Media\u003c\/h4\u003e\n\u003cp\u003eThe filter uses a nanofiber-bonded textile. The fibers are extremely fine, much thinner than the fibers in a standard paper filter, so they can catch much smaller particles without blocking airflow. That includes pollen, dust, and PM2.5. PM2.5 means particles 2.5 microns or smaller, about 1\/30 the width of a human hair. It's the fine soot and smog dust that ordinary filters let through, and the kind that gets deep into your lungs.\u003c\/p\u003e\n\u003ch4\u003eAntibacterial Treatment and Charcoal\u003c\/h4\u003e\n\u003cp\u003eThe filter media has an antibacterial treatment to inhibit mold and bacteria growing on the filter. A damp, dirty filter is exactly where that musty smell comes from. There's also a layer of activated charcoal that soaks up common odors, like exhaust fumes in traffic or the smell of a farm you're driving past. It helps a lot, but it won't block every smell.\u003c\/p\u003e\n\u003ch4\u003eWhen to Change It\u003c\/h4\u003e\n\u003cp\u003eHKS recommends replacing it every year or every 10,000 km (about 6,000 miles), whichever comes first. Change it sooner if you drive in heavy traffic, dusty conditions, or somewhere with a lot of pollution. The filter's behind the glovebox. Empty the glovebox, unclip it so it drops down, pull the filter cover, and slide the old filter out. Put the new one in with the airflow arrow pointing the right way. It takes about five minutes with no tools.\u003c\/p\u003e\n\u003ch4\u003eFitment\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e2016-2021 Honda Civic Si\u003c\/li\u003e\n\u003cli\u003eHKS size: Honda Type 1\u003c\/li\u003e\n\u003cli\u003eDirect replacement for the factory cabin filter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\n \n\u003cli id=\"VehicleFitment\"\u003e\n \u003cp\u003e16-21 Civic Si \u003c\/p\u003e \n\u003c\/li\u003e\n\n\n\n\n\u003cli id=\"TechnicalData\"\u003e\n\n\u003c\/li\u003e\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\u003cli id=\"InstallGuide\"\u003e\n\n\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n","brand":"HKS","offers":[{"title":"Default Title","offer_id":69807780888610,"sku":"HKS-70027-AH001","price":55.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2218\/5701\/files\/21345120.jpg?v=1794520909","url":"https:\/\/www.hybrid-racing.com\/products\/hks-nano-cabin-filter-for-16-21-civic-si-pm25-odor-control","provider":"Hybrid Racing","version":"1.0","type":"link"}
