Particle And Gas-Phase Filtration Meets HyperHEPA Technology
The Atem Car HyperHEPA Plus filter combines advanced particle filtration with gas-phase adsorption technology to help reduce airborne particles, odors, and chemical pollutants inside your vehicle.
HyperHEPA Particle Filtration
Removes ≥99% of airborne particles down to 0.003 microns, including PM2.5, allergens, bacteria, viruses, and ultrafine particulate pollution.
Gas & Odor Filtration
Adsorbs gases, odors, VOCs, and chemical pollutants using integrated gas-phase filtration media for more comprehensive air cleaning.
The air quality solution for your car
Removes over 99% of particles down to 0.003 µm, including particulate matter (PM2.5), diesel soot, allergens, bacteria, and viruses—and simultaneously adsorbs VOCs and odors for comprehensive cabin air cleaning
A high-capacity centrifugal fan at the center of the system draws in cabin air through a combined particle and gaseous filter that wraps 270 degrees around the fan for maximum removal of harmful air pollutants from the air - cleaning your interior air up to 20 times per hour.
Attaches firmly to headrests or seat belts, keeping it safe in motion. With optional USB C connector.

FAQs
Atem Car
The Atem Car uses a HyperHEPA filter that removes over 99% of ultrafine particles down to 0.003 microns, including viruses, bacteria, allergens, dust, smoke, and PM2.5. Making it ideal for personal protection in polluted indoor environments.
Yes. The gas-phase filtration media in the HyperHEPA Plus filter captures VOCs, chemical fumes, and unpleasant odors from traffic, smoke, and cabin materials.
The Atem Car comes with a headrest mount that fits most vehicle seats. It can also be installed with a seatbelt strap for non-headrest setups. The mount has been crash-tested for safety by Germany’s ADAC institute.
The device plugs into your car’s 12V power outlet (cigarette lighter port) using the included adapter. It powers on/off automatically with your vehicle ignition (when using the ignition-linked socket).
The HyperHEPA Plus filter typically lasts up to 12 months with average use (approx. 10 hours per day). The device uses an integrated filter ID chip to monitor usage and alerts you via LED and app notifications when a replacement is needed.
