You may not always be able to see the dander and pollen that floats through the air, but an air purifier traps the germs and allergens that can do a number on your health. However, GermGuardian appliances take purification one step further by also destroying those particles with the help of an internal ultraviolet-C light.

Filtration and Speed

No matter which air purifier you choose, you get the same high-quality filtration technology. The primary filter is a true-HEPA filter, which traps 99.97 percent of bacteria, viruses and airborne irritants. To ensure it remains efficient throughout its lifespan, this filter is coated with an antimicrobial material.

Each model’s true-HEPA filter is protected by a pre-filter. This secondary filter’s job is to capture large particles like dust and hair, keeping them from clogging the true-HEPA filter. To knock out foul odors, the pre-filter has an activated carbon layer.

Plus, you get the benefit of ultraviolet-C light. This tiny light bulb that sits behind the two filters is kickstarted by a titanium dioxide catalyst. When the UV-C light is on, it emits low-frequency light waves, beaming them onto the filter. Within minutes, all the germs on the filter are neutralized.

One of the main differences between of these air purifiers is the speed of the fans. Each model contains a variable-speed fan to push clean air into the room. The AC4300, the AC4825 and the AC5300B have a three-speed fan. To give a performance boost in rooms that require it, the GermGuardian AC5350B’s fan has five speed settings.

Conclusion: GermGuardian offers all the filtration technologies you’d expect from a big-name air purifier manufacturer. Each model has a true-HEPA filter and a pre-filter. Plus, the company uses carbon adsorption to get rid of bad smells, and it even adds a UV-C light to each purifier. Although the AC5350B has five fan-speed settings, you aren’t without options on the other models.

Size and Efficiency

Boxy appliances take up valuable table and counter space. Tower-style appliances are slim space-savers. Each one of these air purifiers by GermGuardian is encased in a tower housing with a sturdy base. Therefore, you can put your air purifier in almost any spot without it dominating the room.

Although all four models are towers, they aren’t all shaped the same. The AC4300, the AC5300B and the AC5350B have squared yet soft edges while the AC4825 is more of a rounded tower.

While the AC4825 model has a matte black finish with a silver chevron at the top, the other three air purifiers are black and glossy.

When it comes to size, the air purifiers are split down the middle. On the smaller end of the spectrum, the AC4300 and the AC4825 measure 22 inches in height with the base of the AC4300 measuring 48 square inches and the AC4825 measuring 71 square inches. The AC5300B and AC5350B are 6 inches taller, and both have a 61-square-inch base.

If energy savings are important to you, you’ll be happy to know that these air purifiers are energy-friendly. The lowest wattage purifier is the AC4300 with an electricity consumption of 52 watts, and the highest energy user is the 57-watt AC5350B.

Conclusion: Space-hogs? Not these air purifiers. Their slim profile and black finish make them attractive for use in any bedroom, living room or home office. Each one draws a different wattage, but that difference is slight. The AC4825 is unique in looks due to the silver accents on the housing.

CADR and Coverage

You won’t have to guess or keep a written schedule of when to change any of the purifier’s filters or bulb. The indicator light on all four air purifiers flashes whenever the HEPA filter or UV-C bulb needs to be replaced. If you choose not to run it, you can turn off the UV-C light bulb with the press of a button.

Some of the GermGuardian air purifiers are designed for smaller spaces than the brand’s other purifiers. The AC4300 and the AC4825 are perfectly suited for cozy areas like a guest bedroom or home office. On the other hand, the AC5300B and the AC5350B are powerful enough to work efficiently in larger rooms such as a den or master bedroom.

Due to the variances in size, shape and speed, the air purifiers also have different CADR, or clean air delivery rates. The AC4300 tops out at a CADR of 116 while the AC4825 has a max CADR of 125. The large-room models come in slightly ahead by a few CADR points.

Their control panels also differ. If you want to stick to something simple, the GermGuardian AC4825 has a dial for the fan and a push button for the UV-C light. If high-tech is more your speed, you’ll love the touch buttons that surround the digital screen on the AC5350B, one of which is an 8-hour timer. The AC4300 and the AC5300B sit somewhere in between with labeled push buttons for all controls.

Conclusion: The dual-purpose indicator for the filter and the UV-C bulb comes standard on every model. However, the controls are different on each air purifier except the AC4300 and the AC5300B. Each one has a decent CADR rating, including the AC4300 and the AC4825, which are the two small-space purifiers.
