Effective, four-filtered purifier with HEPA and UV-C light

The GermGuardian AC5000E gets its 3-in-1 feature from its functions as a HEPA purifier, an UV-C, and as an odor reducer. It uses four cycles of air filtration so more allergens or pollutants are trapped within the HEPA while the UV-C kills bacteria and viruses. If you’re a pet owner or have severe allergies due to poor air quality, this is a great option.

True HEPA filtration

The GermGuardian uses True HEPA filtration, which captures 99.97% of allergens found in dust, pet dander, pollen, smoke, and so on. Whether you have a vacuum that does a poor job of containing dirt and dust, or you live in an area with a lot of pollution, the HEPA is extremely effective and superior to other forms of filtration.

Hospital-grade UV-C light

The other form of filtration in the AC500E is the UV-C light. This is the same kind of light hospitals use to sanitize their air, and it is proven to kill viruses and bacteria that live in the air. The UV-C provides an additional protection to the HEPA.

Filter replacement indicator

Both the HEPA and UV-C bulb will eventually need to be replaced. Instead of having to remember, the GermGuardian has a filter replacement light for both the filter and bulb that will light up when it’s time to change them out. Keeping the filter and bulb fresh and at their best means fresher, cleaner air.


Superior filtration

The main advantage that the GermGuardian 3-in-1 has is its superior filtration. It has a total of three levels: the pre-filter, which catches large debris like pet hair and lint, the charcoal/activated carbon filter that traps gross smells, the HEPA for allergens, and then the UV-C light at the top, for airborne bacteria and viruses. You can rest assured that nothing will get past this air purifier.


A lot of air purifiers do a good job filtering, but they are loud. The GermGuardian is designed to be quieter, so you can leave it on during the night while you sleep for fresh, cough-free bedtime. If your child has asthma, you can leave one in their room and they won’t be disturbed by noise.

Ideal for pet owners

Another plus is that the GermGuardian is very good at getting rid of smells, making it ideal for pet owners. Animals create smells, and if you have birds, dogs, cats, hamsters, or especially smelly pets like ferrets, this air purifier will capture and trap the odor. It also will take care of allergy-causing dander.


UV-C light is very bright

The one main issue with the GermGuardian is that when the UV-C light is on, it’s pretty bright. This is not ideal if you plan on having the unit in your bedroom. Just keep it turned off at night and then run it with the light on during the day.

Overall Review

The GermGuardian AC5000E Air Cleaning System is a very thorough, quiet purifier that uses both HEPA and UV-C light to sanitize and freshen the air in your home. This is especially useful if you have pets who shed hair and dander everywhere, or if you have asthma or any other kind of breathing problem. The GermGuardian 3-in-1 will get rid of pollutants and allergens, and keep your home smelling fresh.
