Today, we’re going to compare two popular air purifier models by GermGuardian and Levoit—the AC4825 and the Core 300 respectively. They look nothing alike and have very different air-purifying capabilities and capacities. So, which should you get? Scroll down to read our full comparison of the GG and Levoit.

Area Coverage
GermGuardian
Air purifiers mainly differ by how wide of an area they can clean. The GG is among the smallest air purifiers on the market despite its towering 22-inch height. With a coverage capacity of 167 square feet, the GG would fit well in single bedrooms, dorms, and kitchens.
Levoit
The tinier 14-inch tall Levoit has a greater reach of 215 square feet. This cute air purifier can handle removing heavy concentrations of airborne pollutants in multiple adjacent rooms at once without taking a ton of floor and air space.

Conclusion
We like to say that bigger is better, but when it comes to air purifiers, it is a different case. You’ll need to measure the square footage of a room or rooms where you plan on placing the device before settling on a model. The Levoit can tackle air-cleaning jobs in a broader selection of rooms compared to the large-yet-limited GG.
CADR
GermGuardian
When shopping for an air purifier, assure to check out its CADR (Clean Air Delivery Rate) figures (if available). They indicate how effective the device works, removing common pollutants from the air. The GG has CADR ratings of 108 CFM for smoke, 125 CFM for pollen, and 118 CFM for dust. These aren’t the best CADR ratings you find, even by small-size air purifier standards, but it does a decent job.

Levoit
On the other hand, Levoit scores 141, 145, and 140 CFM in the same three categories. As you can see, there’s a significant difference between 22 and 33 CFM when looking at the overall picture doesn’t mean much.
Conclusion
From a technical standpoint, Levoit’s higher CADR figures objectively show a more effective air purifier in removing smoke, pollen, and dust from spacious areas. It’s worth noting that CADR ratings can be affected by the type of filter the device uses. True HEPA filters, for instance, can reduce these figures by a substantial amount.
Filter
GermGuardian
The GG comes with its own True HEPA Filter that removes up to 99.97% of airborne particles of 0.3 microns in size or larger. Translation: pollen, dust, dust mites, and dander trapped in the super-fine mesh. It also has a pre-filter for larger debris like hair and an activated charcoal filter to help control odors.
Levoit
The Levoit also uses a True HEPA Filter. The difference is that Levoit offers four different types of HEPA Filters for specific tasks. In no particular order, the filter options are original (comes standard with the Core 300), pet allergy, toxic absorber, and mold/bacteria.

Conclusion
Even though the GG’s filtration setup isn’t customizable, the 3-stage system does the job of all four Levoit filters once without swapping them out. As for the Levoit, unless you have a specific need to remove VOCs, mold, or pet smells, the standard HEPA filter should do the trick. Sadly, it doesn’t come with a pre-filter or deodorizing charcoal filter.
UV-C Sanitizing Beam
GermGuardian
A UV-C beam sanitizes a room by destroying viruses and bacteria at a molecular level. The result is fresher air free of infection-causing microorganisms. The UV-C feature can be turned on and off at will and produces no lung-irritating ozone (unlike ionizers).

Levoit
The Levoit comes with no such feature. No UV-C, no ionizer—just good old air purifying. Is this a deal-breaker? Not at all, but the lack of an optional virus-killing weapon can mean something to people during these trying times.
Conclusion
Having an optional UV-C sanitizing feature is excellent for most conditions. They aren’t 100% foolproof, but the GG’s works well enough that viruses and bacteria are less likely to become the main problem at home.
GermGuardian AC4852 vs. Levoit Core 300: Which Air Purifier Should I Get?
After seeing what each has to offer, we feel that the Levoit Core 300 Air Purifier is the better option of the two but only by a narrow margin. The UV-C sanitizing beam in the GermGuardian AC4852 is a super-handy feature to have, but the higher CADR ratings of the Levoit are hard to ignore. The great news is that both of these devices work beautifully in small spaces.
