Portable Car Air Purifier with HEPA Filter & Negative Ion Technology for Clean Air Circulation

Works great for small spaces like your car or office—basically anywhere under 100 square feet or so—and what it does is pull in air through a HEPA filter (the 42x42x22mm one, which you'll need to swap out roughly every 3-6 months depending on how dusty it gets) plus activated carbon to catch odors from smoke or that leftover fast-food smell from yesterday.

Runs off USB 5V, so you can your car's lighter adapter or a laptop port, and it only draws 0.6W—pretty much negligible for battery drain. Noise stays under 40 dB on low, which is quieter than most car fans, but on high you'll definitely hear it humming away (still not annoying). Most buyers go with the 2-speed setting; higher flow pushes about 50 m³/h, enough for a sedan cabin.

Negative ion output is 10 million pcs/cm³, and that's what it basically uses to help settle fine particles the filter might miss, but don't expect it to kill viruses or anything—that's not what this is suited for. We've had some customers try it in a small bathroom or closet, and honestly it's better than reagent-grade HEPA units for tight spots, but the effective area is really under 10 m² give or take.

Control is a single button that cycles through two fan speeds and the 7-color lighting options (which you can leave off if you don't want the disco vibe). One detail most people don't think to ask: teh filter dimnesions are non-standard at 42x42x22mm, so replacement filters are pretty much only form us or a few third-party sellers—check lead time on those.

Comes in a color box (75x75x170mm), and we pack 50 per carton, MOQ is 50 pieces by the way. Weight is about 300g, so it's light enough to toss in a glove box.
