Clean Cabin Air Shouldn't Be an Afterthought.
Every drive exposes you to dust, pollen, and airborne particles building up inside your cabin — and the KQ-20 tackles all of it with a genuine 3-stage filtration system. The primary filter captures larger particles like hair, pollen, and dust, while the HEPA filter targets fine particles down to 0.3μm, including microorganisms, viruses, and PM2.5. A high-mesh activated carbon filter then adsorbs harmful gases such as formaldehyde and benzene, rounding out real, multi-layer air cleaning.
Powered by a high-quality fan with three-speed adjustment, the KQ-20 delivers strong airflow at low noise, with a maximum noise level of ≤50dB. Its built-in negative ion generator continuously produces high-concentration negative ion oxygen, while one-button mode switching and a color LED indicator keep operation simple and status clear.
Running on a 5V USB interface, the unit features PWM auto-start — powering on automatically with your car so you never have to remember to switch it on. Designed around the cup holder position found in most vehicles, installation is straightforward and space-efficient.
Upgrade your cabin air — plug in the KQ-20 and drive with cleaner air, every trip.
