- Does the GG1100 have a HEPA filter?
- No. It uses a UV-C light and an ionizer, not a HEPA filter, so it does not trap fine particles the way a HEPA purifier does.
- What size room is it for?
- It is built for a desk, nightstand, closet or small bathroom. It is not meant to clean a full bedroom or living room.
- Is it loud?
- Owners describe it as quiet, quiet enough to run overnight near a bed.
- Does it need filter replacements?
- There is no HEPA filter to replace. The UV-C bulb is the part that wears out over time.
- Does the ionizer produce ozone?
- Ionizers can produce trace ozone. If you are sensitive to ozone, run it with the ionizer off or choose a HEPA-only purifier.
- How does it compare with a HEPA tower purifier?
- A HEPA tower moves much more air and captures particles. The GG1100 is smaller, quieter and cheaper to run, but it is a supplement, not a substitute.
- Where is the GermGuardian GG1100 cheapest?
- At Quill, for $61.99, as of our latest check.
