Which is better for a bedroom?

The Sharp is the safer pick for a bedroom. It has a True HEPA filter, a sleep mode, and a higher CADR, and it costs less. The Ionic Pro is quieter but cleans less air per minute.

Which cleans a larger room?

The Ionic Pro claims up to 800 sq ft, but its CADR is about half the Sharp's. For a 259 sq ft room at 4.8 air changes per hour, the Sharp is the tested choice.

Is the Ionic Pro worth the extra money?

Only if you want no filter replacements and near-silent running. At $339.95 versus $179.99, you pay about $160 more for lower CADR and an ozone rating of 3.0.

The Ionic Pro has no filters to replace, so its plates can last for years with wiping. The Sharp needs new HEPA and carbon filters about every 2 years, but the unit itself is durable.

Does either one produce ozone?

The Ionic Pro lists ozone emissions of 3.0. The Sharp is CARB certified and lists no ozone emission figure.

Do either have app control?

No. Neither the Sharp FP-K50UW nor the Ionic Pro Platinum has app or remote control.
