Ozone Showdown: Portable Purifier Versus Odors… Surprising Car Cleanup We recently put the LKT Car Ozone Generator to the test, needing a solution for our car’s lingering smoke odor. After 30 minutes of treatment on a medium setting, the results were striking. The once-pungent aroma vanished, leaving behind a clean, neutral scent. The device’s portability was a standout—easy to move from the car to our home’s bathroom to neutralize pet smells there—and its compact design fit snugly under our seat without hassle. While it requires proper ventilation during use, the quick and efficient odor elimination made it a worthwhile purchase. Surprisingly, even old smoke residues seemed to yield. For us, the LKT generator delivered reliable freshness across multiple surfaces, proving its versatility beyond just cars.
