What size room is the FPK50UW rated for?

Sharp rates it for rooms up to about 300 square feet. That fits a bedroom, office or small living room, not an open-plan space.

Does it have a HEPA filter?

Yes. It uses a true HEPA filter for particles plus a carbon filter for odors, and part of the filter setup is washable.

No. You choose among three fan speeds yourself. There is no sensor, timer or app control.

It emits trace ozone, within regulated limits. If you are sensitive to ozone or have asthma, leave the ionizer off and rely on the HEPA filter.

The low speed is quiet enough for a bedroom. The top speed is clearly audible and better suited to short cleanup runs.

The purifier ships with its filters installed. Check that the HEPA and carbon filters are seated before first use.
