Does it really filter 99.97% of particles?

That is the standard HEPA rating for 0.3-micron particles, and the listing claims it. Real performance depends on filter fit and seal, and no independent test is published for this unit.

Will it help with smoke or cooking smells?

The activated carbon layer is meant to adsorb odors, so it can take the edge off light smoke or food smells in a small space. It holds little carbon, so it will not clear a kitchen or a smoky room.

What do the negative ions do?

They can help fine particles clump and settle. Claims about mood or health are not well supported, and the filter does most of the real work.

It runs from a USB port or a 12V car socket, which makes it easy to move between a desk and a vehicle. It draws little power.

How often do I change the filter?

The listing gives no schedule. In a dusty room or a car, plan on replacing it every few months, and check that filters are still sold before you buy.

Is it enough for a bedroom?

It is a desktop unit with a small fan, so treat it as a personal-space purifier. For a full bedroom, a larger purifier with a published CADR is the better fit.

Our take on the Yyuzh Air Desktop Purifier with Negative Ion Generator

The Yyuzh Air Desktop Purifier is a small plug-in air cleaner with a HEPA-type filter, an activated carbon layer for odors, and a negative ion generator. It is built for a desk, nightstand or car, powered over USB or a 12V socket. The filtration and odor claims are the same ones budget desktop purifiers make, and the ion generator adds little that the filter does not already do. It suits light, close-range use, not a whole room.
