A speaker-like design, GermGuardian AC4100 is a compact (6.5 x 11 x 7.5 in (16.5 x 27.9 x 19.1 cm)) and lightweight ([aweight)] air purifier that does not fall short on build quality. You can easily place the air purifier at any corner of the room, shelf or table desk. On to usability, GermGuardian AC4100 is very simple to use as there is only one front dial knob for fan speed control and UV-light button. Other than that, there is nothing much in GermGuardian AC4100 other than filter replacement indicator and a standard 1 year warranty.

As an entry-level compact air purifier, GermGuardian AC4100 estimated 60 sq. ft. purifying coverage is not great. Probably best use in close range within a small room size. The 3 speed airflow delivery rate isn't any better either although that is expected given the air purifier targeted group. No official CADR but it should follow the similar low output pattern.

^ GermGuardian AC4100 filters/ technologies/ lifespan
As mentioned earlier, GermGuardian AC4100 is a 4-stage filtration at a very compressed body. You have the initial carbon pre-filter that handles large and smoke/ odors based particles. With those particles out of the way, the HEPA filter would uninterruptly and freely capture smaller micron size particles. As for notorious and tricky allergens including bacteria and viruses, you have the last stage UVC-light + PCO filter standing by for the last round elimination before releasing the purified air out.

In general GermGuardian AC4100 effective plus purifying coverage and airflow delivery rate is magnificent in clearing away common airborne pollutants notably dust, pet hair. stand up against allergens, irritants, bacteria, GermGuardian AC4100 bundled , 3 fanspeed and 4-stage filtration is at somewhat average grade in destroying mold, spores, mildew, pollen, germs, dust mites and pet dander.  On odors, smokes and fumes, GermGuardian AC4100 filtration is weak in tackling cooking odors, radon, ammonia chemicals, VOCs, tobacco and cigarette smokes.

Keep it down

GermGuardian AC4100 has a very decent noise level return that triumph most air purifiers in the category. At low to medium speed, barely any noise can be heard and mild noise at higher speed. Great for all occasion but works best for night use. Power consumption is equally good with overall low usage at all speed.

Other than the different variants from GermGuardian, GermGuardian AC4100 it's the only few affordable air purifier that comes with carbon pre-filter and UV-C light. While the comprehensive 4-stage filtration is good to have, it does add-up to the annual maintenance cost although not much. Do keep in mind that the recurring cost will eventually stack up in long-run that might not be so feasible for those looking for an one-off deal. For a more "permanent" one time solution, see the below options.

The challengers

Hamilton Beach TrueAir Compact Pet 04384

Hamilton Beach TrueAir Compact Pet 04384

Similar price range that utilize a permanent HEPA-grade filter with very low annual replacement cost. Downside is the weaker filtration depth and lacks UV-light technology.

Airfree Iris 3000

Only one-off fee with absolutely no recurring cost as it uses Patented Thermodynamic TSS Technology purification. Purifying coverage is not great either and very expensive to begin with.

In conclusion......

  • Beautiful speaker-like body that is compact yet reliable.
  • Affordable price for a 4-stage filtration air purifier with UV technology.
  • Enhanced Charcoal + PCO Pre-filter that works well with HEPA filter.
  • UV-C light technology that can be turn off.
  • Filter replacement indicator.
  • Below average purifying coverage and filtration strength.
  • Annual filter replacement cost is high for its segment.
  • No addon features although understandable given its size and price tag.
