Does it really purify a car's air?

It passes air through a small physical filter and releases negative ions. That can help with dust and odors in a confined space, but there is no fan or CADR rating, so expect light local cleaning rather than fast, measurable filtration.

How does the humidifier work?

It is a mini humidifier built into the same unit, meant to add moisture in dry, heated or air-conditioned spaces. The reservoir is small, so it runs for short stretches and needs frequent refilling.

Can I power it from a power bank or laptop?

Yes. It runs on 5V USB through the included cable, so a car charger, power bank or laptop port all work. There is no internal battery, so it stops when unplugged.

How often do I replace the filter?

The manual gives the recommended interval; the box includes one spare filter. In dusty cars or rooms, check the pad more often and replace it when it looks loaded.

What comes in the box?

The purifier, one replaceable filter, a USB power cable and a user manual.

Is it a replacement for a home HEPA purifier?

No. It is a personal, small-space device for a car, desk or bedside. A full-size HEPA unit with a rated CADR is the better choice for cleaning a whole room.
