It features a True HEPA filter with a 2-stage filtration system that effectively eliminates 99.97% of dust, odors, allergens, and other airborne particles. The activated carbon pre-filter handles odors and harmful gases, while the True HEPA filter tackles dust, dander, pollen, mold spores, and smoke. This makes it a robust choice for those dealing with allergies or seeking cleaner air in confined spaces.

Its cordless design and rechargeable lithium-ion battery, which lasts up to 12 hours, add to its portability and convenience. The USB-C charging ensures fast and reliable power replenishment, and weighing less than 1 pound, it is easy to carry around. The adjustable handle and three fan speeds allow for customized use, and the purifier can even function as a personal cooling fan on high settings.

While its CADR of 4 CFM means it covers a small area (6ft² in 12 minutes), it is intended for personal use rather than large spaces. The noise level of 50 dB may be noticeable in quieter environments. Maintenance is straightforward with a twist-off base for quick filter changes. It also comes with a 5-year manufacturer’s warranty, offering peace of mind. However, it might not be suitable for larger vehicles or rooms due to its limited coverage area.

The IQAir Atem Car Portable HEPA Air Purifier stands out in the car-air-purifier category with its advanced HyperHEPA filtration technology that captures ultrafine particles as small as 0.003 microns.

This air purifier is particularly suited for individuals who spend considerable time in their cars, such as commuters or drivers in areas with high air pollution. Its high-efficiency filter is a significant plus.
