Does it need a filter replacement?

Yes. The HEPA filter is replaceable and should be changed when it darkens or airflow drops. The UV-C lamp also has a limited life and needs periodic replacement.

How large a room can it handle?

It is built for small rooms such as bedrooms and offices. It will not keep up with a large open-plan space.

Does it have an auto mode?

No. You pick one of three fan speeds manually. There is no air-quality sensor or automatic adjustment.

The lower speeds are quiet enough for a bedroom. The highest speed is noticeably loud.

Does the UV-C light run all the time?

The UV-C light works alongside the fan and filter. It is part of the unit's normal operation rather than a separate mode.

Our take on the GermGuardian HEPA Filter Air Purifier with UV-C Light, AC4711W

The GermGuardian AC4711W is a portable plug-in air purifier that pairs a HEPA filter with UV-C light. It has three fan speeds and runs on standard 120V AC power. It suits bedrooms, offices and small living spaces where dust, pollen and pet dander are the concern. Against rivals, it adds UV-C treatment that most budget HEPA purifiers skip, but it lacks the air-quality sensors and auto mode found on smarter models.
