- What size room is the AC5350B good for?
- It is rated for rooms up to about 167 square feet, so a bedroom, office or small living room. Larger or open rooms will need a unit with a higher CADR.
- Does it really need a UV-C bulb?
- The UV-C light is an extra stage on top of the HEPA filter, not a replacement for it. You can run the purifier without it, but the bulb has to be replaced periodically to keep that function working.
- How often do filters need changing?
- GermGuardian advises replacing the HEPA filter roughly every 6 to 8 months depending on use, and the charcoal pre-filter more often. The unit has a filter indicator to remind you.
- Is it loud enough to disturb sleep?
- On the lower speeds it is quiet enough for most bedrooms. The top speeds are clearly audible, so light sleepers should plan to run it low overnight.
- How does it compare with the AC4825?
- The AC5350B is a taller tower with five speeds, a digital display and a timer, while the AC4825 is a simpler three-speed unit. Both use HEPA filtration, so the choice comes down to whether you want the extra controls.
- What comes in the box?
- The purifier ships with a HEPA filter and charcoal pre-filter installed, plus a UV-C bulb. No extra filters are included.
