GermGuardian Air Purifier Reviews

1. GermGuardian AC5900WCA

Like the AC4825, this air purifier catches up to 99.97% of pollutants as small as 0.3 microns using a True HEPA filter. Odors and smoke are removed through an activated carbon filter, and UV-C light technology kills germs like influenza and rhinovirus. If you’re trying to protect your loved ones from diseases and allergy attacks, the AC5900WCA can get the job done in larger rooms that are up to 338 sq. ft.

Although this air purifier’s physical dimensions make it bulkier than its tower-type siblings, its sleek white finish is easy on the eyes. It also has the convenience of having an 8-hour auto-off timer and three speed levels, but an auto mode is yet to make an appearance on its features list. It’s not as affordable as the usual GermGuardian model, but it’s still reasonably-priced for the coverage and technologies that it provides.

Pros

  • Removes particle pollutants, smoke, odors, and airborne germs
  • Has titanium dioxide UV-C technology
  • Comes with a filter replacement indicator
  • Three speed levels and 8-hour timer
  • Easy to maintain
  • Reasonably-priced

Cons

  • No auto mode
  • Large, bulky

2. GermGuardian AC4825

GermGuardian’s AC4825 is an air purifier that uses three stages to clean the air. It has a True HEPA filter to remove particle pollutants (dust, dander, and pollen), a carbon filter to remove smoke, VOCs, and odors from the air, and a titanium dioxide-assisted UV-C lamp to help neutralize airborne bacteria and viruses. That being said, it’s clear that the AC4825 has something for virtually every type of air contaminant. Also, it’s designed for use in small to medium rooms that are up to 167 sq. ft.

This GermGuardian air purifier comes with a filter replacement indicator and three speed levels. However, it doesn’t have a programmable timer or special modes like a sleep mode or an auto mode. No matter how simple its profile is, customers will likely appreciate the fact that its filters last for up to 8 months. This makes the AC4825 a low-maintenance air purifier

Pros

  • Removes dust, pollen, smoke, odors, and airborne viruses and bacteria
  • Has titanium dioxide UV-C technology
  • Comes with a filter replacement indicator
  • Easy to maintain
  • Three speed levels
  • Affordable

Cons

  • No auto mode
  • No programmable timer

3. GermGuardian AC4300BPTCA Elite

This air purifier, which is targeted towards pet owners, has a True HEPA filter that captures 99.97% of particle pollutants like pet dander, dust, and pollen. This is great news not only to pet parents but to allergy sufferers, too. The True HEPA filter had also been treated with the Pet Pure antimicrobial agent to inhibit mildew, mold, and odor-causing bacteria. Lastly, this model has a carbon filter and UV-C light technology—both of which strengthen its stance against odors, VOCs, germs, and smoke.

Made for spaces up to 153 sq. ft., the AC4300BPTCA can be a helpful addition to small to medium spaces like pet play areas. It also features three speed options and a filter replacement indicator. Unsurprisingly, it skips on having fancy modes and a programmable timer just like most of the models mentioned here. Still, if you’re looking for a fairly-straightforward air purifier for pet-related concerns, this model is an affordable yet promising option.

Pros

  • Removes dust, pollen, smoke, odors, and airborne viruses and bacteria
  • Has titanium dioxide UV-C technology and the Pet Pure treatment
  • Comes with a filter replacement indicator
  • Easy to maintain
  • Three speed levels
  • Affordable

Cons

  • No auto mode
  • No programmable timer

4. GermGuardian AC4100

The GermGuardian AC4100 is the most affordable purifier on this list. It also features three technologies to remove pretty much all types of indoor air pollutants, but it doesn’t sport a True HEPA filter. Instead, it has a HEPA-type filter that removes particle pollutants like dust and pollen—but in a less efficient manner than True HEPA GermGuardian models. This, along with its limited coverage of 60 sq. ft., explains its CADR ratings.

Although it’s evidently not the best model for people with respiratory sensitivities, it’s still a good basic model for day-to-day use in small spaces. Its compact form makes it a good desktop air purifier that’s easy to carry from room to room. It’s also easy to maintain—with filters that can last for up to 9 months.

Pros

  • Removes dust, pollen, smoke, odors, and airborne viruses and bacteria
  • Has UV-C technology
  • Compact and portable
  • Easy to maintain
  • Three speed levels
  • Affordable

Cons

  • Not True HEPA
  • Limited coverage
  • No auto mode and programmable timer
  • Short warranty

5. GermGuardian AC5000

The GermGuardian AC5000 is another 3-in-1 air purifier. Like many of its siblings from the same brand, it also uses a True HEPA filter for trapping pollutants like dust and pollen, an activated carbon filter for removing odors and smoke, and a titanium dioxide UV-C lamp for combatting airborne germs. It’s suited to run inside small to medium rooms that are up to 180 sq. ft. in area.

The AC5000 has a filter replacement indicator to notify you when the filters are in need of changing. You’re also allowed to manually choose among three speed options depending on the level of pollution in the room. Unfortunately, this air purifier doesn’t have an auto mode or special sensors.

If low-maintenance air purifiers are important to you, the AC5000’s filters last quite shorter at around 6 months. Therefore, you’ll have to be willing to do at least two filter replacements annually with this model.

Pros

  • Removes particle pollutants, smoke, odors, and airborne germs
  • Has titanium dioxide UV-C technology
  • Comes with a filter replacement indicator
  • Three speed levels
  • Easy to maintain
  • Lengthy warranty
  • Affordable

Cons

  • No auto mode
  • No programmable timer

Frequently Asked Questions

Are True HEPA filters important for UV air purifiers?

When it comes purifying the air, True HEPA filters are considered the gold standard. It is the best at removing air pollutants as small as 0.3 microns, including dander, mold, dust mites, bacteria and viruses.

Carbon is known for being able eliminate odors that come from cooking and smoke. Air purifiers with thicker, denser carbon filters do a better job of removing odors, VOCs, and chemical fumes. If these are problems that you’re facing at home, then yes, carbon filters are very important!

How often do I need to change the UV light bulb of my air purifier?

UV light bulbs tend to last anywhere between 12 and 24 months, depending on the brand and usage. It’s best to check the instruction manual for instructions on maintaining your UV light bulb.

Final Thoughts

The GermGuardian AC4825 definitely impresses with its lineup of technologies that comes at a very affordable price tag. However great its value-for-the-price is, we know that its relatively-small coverage and simple profile isn’t for everyone—and for that, the GermGuardian AC5900WCA takes the spot of the deserving alternative. Its wide coverage and programmable timer make it a competitive model albeit at double the cost.
