Guardian Technologies GermGuardian True HEPA Filter Air Purifier
We purchased the GermGuardian AC4825 3-in-1 Air Purifier so our expert reviewer could thoroughly test and assess it. Keep reading for our full product review.
Indoor air contains pollutants and particles that can affect your health. Everything from cooking and cleaning to outdoor air and dust can contribute to not-so-clean indoor air, but there are ways—like using an air purifier—to limit them. At its most basic level, an air purifier works by sucking the air in your home through a series of filters, and then circulating the purified air back into the room. This process is repeated several times per hour to ensure the air remains clean.
Air purifiers with HEPA filters can remove at least 99.97 percent of dust, pollen, mold, bacteria, and any airborne particles with a size of 0.3 microns, like tobacco smoke. While high-end air purifiers can cost hundreds of dollars, there are some options that are just as effective (maybe even more so) and won’t break the bank. Read on for our assessment of the GermGuardian AC4825 3-in-1 Air Purifier—a mid-range model with a great warranty.
Setup Process: Set it and forget it
Pop the GermGuardian 3-in-1 out of its box and the device is ready to go. The air purifier ships completely assembled and with its filter in place. The machine requires a filter replacement every six to eight months, but you’ll know it’s time when the machine’s indicator flashes red.
The filter is very easy to replace, but must be purchased separately at a cost of about $35. There are slightly cheaper filter options if purchased from a third-party vendor, but we recommend sticking with Guardian Technologies’ official filters as anything else can be risky if you don’t know what kind of quality you’re getting.
Performance: Air purification perfection
The GermGuardian 3-in-1 is impressive in its ability to collect dust and eliminate odor. This model is designed to purify air in medium-sized rooms that are about 167 square feet—roughly the size of a 10 x 16.5-foot room.
After running it in our home for a few weeks, we noticed a definite difference in dust and tough pet odors.
The “3-in-1” feature describes this model’s three-part air filtration process. First, air is filtered through a pre-filter—an activated charcoal layer which is a special type of carbon that catches larger particles and kills unwanted odors. Second, a HEPA filter is used to catch fine, microscopic particles like pollen, dander, and dust. HEPA filters are expensive, but extremely high-quality because of their ability to trap minuscule particles in comparison to other standard home filter systems. The third and final filtration system is also what makes the GermGuardian Air Purifier quite unique. This model uses a UV-C, or Ultraviolet-C light, that kills airborne bacteria and germs that are known to cause certain allergies and diseases.
GermGuardian claims their 3-in-1 air purifier is equipped to remove the following air contaminants: pet dander, pet hair, dust mites, pollen, home construction particles, smoke residue, and chemical and organic odors. After running it in our home for a few weeks, we noticed a definite difference in dust and tough pet odors.
Design: Not winning any awards for style but...
We can’t say that the word “stylish” would ever come to mind when describing the GermGuardian 3-in-1, but it’s definitely efficient. This model features a tower design with a height of 22 inches, and while it’s not the most discrete appliance, we wouldn’t consider it to be a complete eye sore. The device does require some space, so be sure you have a buffer of about 2 feet around the front and back. Don’t tuck the air purifier into a corner as it won’t be able to efficiently circulate air. If you need to move the device to a different room, you’ll find it’s relatively light and a convenient built-in handle makes it easy to maneuver.

This model’s unique Ultraviolet-C light does require a blue light to be on, which could be distracting to a sensitive sleeper. Thankfully, this feature is optional and can be turned on and off by the push of a button. In terms of noise, this is a very quiet machine with three different levels of speed. Even on the highest setting, the purifier is no louder than white noise. For everyday use, we found the lowest setting to be sufficient and silent.
Price: Not bad, considering
With an MSRP of $150, this model is reasonably priced and in line with other efficient purifiers of the same size. It doesn’t skimp on quality and even features some of the same technology as pricier models. This is a high-quality appliance that performs and comes with a great warranty that’s definitely worth your investment. However, if your concerns reside in appearances, then you might opt for a more modern-looking machine.
GermGuardian AC4825 3-in-1 Air Purifier vs. Levoit LV-H132 Compact HEPA Air Purifier
While the GermGuardian AC4825 is an affordable and efficient air purifier, Levoit’s LV-H132 is also comparable in price and performance. Levoit’s model stands at about 15 inches tall and weighs 6.5 pounds compared to the GermGuardian model, which is about 22 inches and weighs 7 pounds. Both models use the same 3-in-1 filtration technology and feature a UV-C light, but Levoit’s model includes two brightness settings, whereas the GermGuardian can only be switched on or off. Both models require filter replacements after six to eight months (depending on usage) and include light indicators that alert when it’s time to replace.
The major difference between the models is their design, price, and warranty. The Levoit model is lower to the ground, a touch more attractive, and comes in white and black. Levoit’s model is about $60 cheaper than the GermGuardian, but it only comes with a 2-year warranty, whereas the GermGuardian has a 3-year warranty. This battle here really comes down to aesthetic preference, price, and warranty. If your home decor is predominantly white, you may want to choose the Levoit model, but if you want the reassurance of an additional year of warranty and don’t mind the size or color, then stick with the GermGuardian.
Get it and your sinuses will thank you.
If you live with pets, have seasonal allergies, or reside in a heavily polluted city, an air purifier will make a serious difference in your home’s air quality. Though the GermGuardian is a bit of an investment, it’s a top-of-the-line product that performs exactly as promised.
