What does the 4-in-1 filtration include?

A HEPA filter for particles, a charcoal filter for odors, a UV-C light stage and a pre-filter that catches larger debris before the main filters.

How large a room can it handle?

It is rated for rooms up to 153 square feet, so a bedroom, office or small living room. Larger or open-plan spaces need a bigger unit.

How often do the filter and UV-C bulb need replacing?

The unit has indicator lights for both. Filter life depends on use and air quality, and the UV-C bulb is a consumable that needs periodic replacement.

Does the UV-C light run all the time?

No. UV-C has its own control on the digital panel, so you can switch it on or off independently of the fan.

Can it run at night without disturbing sleep?

Yes. The lowest of the five speeds is designed to run ultra-quiet, and the timer can shut it off after a set period.

Our take on the GermGuardian Air Purifier with HEPA Pure Filter and UV-C Light, AC4870

The GermGuardian AC4870 is a 22-inch tower air purifier that combines a HEPA filter, a charcoal odor filter and a UV-C light in one unit. It is rated for rooms up to 153 square feet, so it suits bedrooms, offices and small living rooms rather than open-plan spaces. It offers five fan speeds, a programmable timer up to 8 hours and separate UV-C control, with indicator lights for filter and bulb replacement. Against larger HEPA towers it trades coverage area for a slimmer footprint and quieter low-speed running.
