Performance

The purifier effectively cleans the air in a standard car cabin (3-4m³) within 5-10 minutes. The HEPA H13 filter captures 99.97% of particles down to 0.3 microns. The activated carbon layer absorbs odors from smoke, food, and pets. The PM2.5 display shows the air quality dropping in real-time.

“I smoke in my car sometimes (bad habit, I know), and this purifier clears the smoke within 3-5 minutes. The PM2.5 display shows it dropping from 300+ to under 10. It also helps with my seasonal allergies when driving with windows down. The filter lasts about 4 months for me. The auto mode is convenient — it ramps up when I enter the car and the air is stale.” — JD.com user

FAQ

Q: Does this purifier filter COVID-19 particles? A: The HEPA H13 filter captures particles down to 0.3 microns. COVID-19 virus particles are ~0.1 microns but travel within larger respiratory droplets (5+ microns) which are effectively captured.

Q: Can I hardwire this purifier instead of using the 12V socket? A: The included power adapter plugs into the 12V socket. Hardwiring would require cutting the cable and connecting to a 12V accessory circuit. Some users report success but it voids warranty.

Q: How often should I replace the filter? A: Xiaomi recommends every 3-6 months depending on air quality conditions. The purifier has a filter life indicator that shows when replacement is needed.
