The GermGuardian has anchored Guardian Technologies’ air purifiers in the low-range market in the USA. The company launched its first classic GermGuardian, the GermGuardian AC5000, and it was well received here. Knowing the potential of the AC5000E device, Guardian Technologies invented a 22-inch version of this successful air purifier and reduced the cost even further. Today, we are having a GermGuardian AC4825 Review to check out one of the best and most popular air purifiers in the line of GermGuardian machines.
The GermGuardian AC4825E has been the company’s most famous air purifier for a long time. It has a cheap but effective air filtration system and has been the best air purifier for mold for a long time.
Update: The flagships of this brand are the GermGuardian AC9400W and GermGuardian AC9600W. But if you are looking for a smart air purifier, you should search for either the GermGuardian CDAP5500BCA or the GermGuardian CDAP4500BCA.
In Breathe Quality, we have reviewed all air purifiers under these sections. Also, we guarantee that:
- We provide honest reviews (both pros and cons) so that everyone can make the best decisions.
- We do not (and never will) exaggerate one product just to let you click the links and buy that product blindly.
- Good performance for the money with UV-C light and True HEPA filter
- Best value
- 3-year warranty
- Quite noisy at highest setting
- Lacks of Smart features
Guardian Technologies has already had one big success in last year, selling over a million units of its devices. The U.S company hopes to keep that momentum going with the GermGuardian AC4825, which brings both True HEPA filter and an UV-C light to the budget segment. We try to find out in our GermGuardian AC4825 Review (or GermGuardian AC4825W Review, the white version of GermGuardian AC4825).

GermGuardian AC4825 Price
As the smaller version of the GermGuardian AC5000, the GermGuardian AC4825 will have a better price tag. You will get an under $100 air purifier with all the benefits a true HEPA air filter could provide. For the same price, only Honeywell HPA060, Levoit LV-H132, AeraMax 100 and PureZone are the most well-known opponents of this GermGuardian AC4825.
GermGuardian AC4825 is available for $99, but if you follow our link below, you will enjoy the discount. There is also a GermGuardian AC4820 with exactly the same machine as our current unit, only without an UV-C light filter. I recommend that you stick with the GermGuardian AC4825 for added protection against viruses and bacteria.
If you are looking for the no-UV light filter version of this GermGuardian AC4825, you should look for the latest GermGuardian AC4200W, which is also more compact than our current unit with only 13.5 inches in height.

GermGuardian AC4825 Design and Size
Notice that you can get the White version of this air purifier under the name of the GermGuardian AC4825W. Our testing model is the Black version, but due to the manual from Guardian Technologies, both air purifiers meet the same specifications. So if you are looking for a GermGuardian AC4825W Review, you can also read our review today.
One of the first things you notice when you have a GermGuardian AC4825 in your home is that, despite its 22-inch height, the design of this air purifier is overall the same as that of its bigger brother, the GermGuardian AC5000.
Follow this design language, and this 22-inch air purifier is ready with an air output grill from the front and an intake grill from the back. This classic airflow is the unique feature of GermGuardian air purifiers and increases the efficiency of their fan.
Also, at the top of the GermGuardian AC4825, you will find a twin control panel with the AC5000E, with only one UV-light button, one on/off button, one fan speed switch, and a LED filter replacement indicator.
At roughly 7 lbs, the GermGuardian AC4825 air purifier is even lighter than the CDAP4500BCA which weighs 9.45 lbs. With a relatively small size, the GermGuardian AC4825 is compact and therefore easy to bring anywhere in your home.

GermGuardian AC4825 Filters
GermGuardian AC4825 has a 3-in-1 air cleaning system with the following air filters:
- Pre-filter – Combining with the Activated Carbon filter, this layer of air filter can remove most of the large particles of pollutants and reduce odors created by smoke, cooking, and pets.
- True HEPA filter – GermGuardian AC4825E makes use of a True HEPA filter to capture 99.97% of microscopic allergens, dust, and mold spores down to 0.3 microns in size.
- UV-C Light – With an UV-C light bulb, the GermGuardian AC4825E can kill airborne bacteria, viruses and mold spores.
GermGuardian AC4825 is powered by the same True HEPA filter from Guardian Technologies, the FLT 4825 filter-B HEPA, to help capture the tiniest contaminant particles as small as 0.3 microns, including dust, dust mites, pollen, pet hair, pet dander, and any other allergens. Just like the bigger version, the GermGuardian AC5000, the GermGuardian AC4825 has one pre-filter with an activated carbon layer attached to reduce smoke and odors. Apart from these typical filter layers, the GermGuardian AC4825 supports an UV-C light bulb to enhance the power of killing mold and viruses.
To test the performance of this GermGuardian AC4825, I put it in a comparison with the Honeywell HPA020B and Levoit Vista 200. They are all in the same test conditions: a room of 100 square feet with a duration of 1 hour. With double the standard room size, the Honeywell HPA020B fell to only 99.7%, while the GermGuardian AC4825 was still 99.9% effective at capturing as small as 0.3 microns of particles. The Levoit Vista 200 also had lower performance, with only 99.7%.
As usual, you need to change the air filter every 6–8 months based on 24/7 use. Thanks to its smaller size, the filter-B HEPA is also less expensive than the common filter-C of GermGuardian 28-inch air purifiers.

GermGuardian AC4825 Room Coverage
The ACH of GermGuardian AC4825 is 4X, which is also the same with every device from this brand.
The CADR of GermGuardian AC4825 is 118 Dust/ 108 Smoke/ 125 pollen (cfm). Despite featuring an older air filtration process, the CADR rating of this air purifier is even better than the latest portable device from Guardian Technologies – the CDAP4500BCA.

GermGuardian AC4825 Sound
Using the same three fan speeds as its bigger brother, the GermGuardian AC4825’s noise level is better than that of modern devices, which commonly come with five fan speeds. A smaller size also helps reduce the fan’s size and, as a result, reduce the noise, but only at the highest fan speed.
At the lowest setting, the noise level of the GermGuardian AC4825 is still 40 decibels, which is higher than most of the normal air purifiers on the market. For example, the AeraMax 300 is only 35 decibels, the SilverOnyx can be as low as 25 decibels, and the Winix 5300-2 is only 28 decibels.
But when you switch to the highest setting, the noise level of the GermGuardian AC4825 is only 55 decibels (dB), which is lower than the common 60 dB of the GermGuardian AC5000 or GermGuardian AC5350B. This is still near the noise level of the public restaurant or an AC unit at 100 feet. But still, better is better.
However, the noise level of this air purifier doesn’t fare well in quiet places, but you will still notice a clear sound, especially when running at the highest setting. That’s why we believe that the GermGuardian AC4825 is still not suitable for your office or bedroom.

GermGuardian AC4825 Power Consumption
To be one of the best air purifiers, a device must strictly pass our Breathe Quality test after long-term use. Also, one of the most frequently asked questions in Breathe Quality is: “Do air purifiers use a lot of energy?” We can all agree that power consumption is one important criterion to review to determine if this air purifier is worth your money or not.
Using a 5-watt UV-C bulb, the GermGuardian AC4825’s power consumption is 53 watts. It is still higher than many other energy-saving air purifiers on the market, like the Blue Pure 411, Levoit LV-H132, SilverOnyx, or AeraMax 100. However, this is an Energy Star air purifier because it has a very small CADR/watt rate.
For using a GermGuardian AC4825 for 8 hours per day, it would cost you up to $19 per year.

GermGuardian AC4825 Additional Features
The GermGuardian AC4825 is in fact a smaller GermGuardian AC5000, so just like its brother, this air purifier doesn’t bring any additional features except a LED notification for filter replacement. Once again, we must remind you that this air purifier was superseded by the latest CDAP4500BCA long ago, so you should not expect much from an air purifier under $100.
GermGuardian AC4825 Customer Service
There is not much to say about the brilliant support from Guardian Technologies’ customer service. Anyone can get active support from the American brand. The company also makes the instruction manuals available online to help you answer common questions on your own. But if you can’t find a solution, just contact customer service via phone at 866-603-5900 or via email at firstname.lastname@example.org. Just like any other brand, the office will be open from Monday to Friday.
Guardian Technologies occasionally offers free shipping as well as a significant discount on all products (typically 10% to 20%). Whenever you find the air purifiers are not as great as you had thought, you can return them within 30 days of your original receipt of the order. And don’t worry about the warranty policy of Guardian Technologies, as it warrants its products to be free of defects in materials or workmanship. You can register for a warranty for up to five years.
For the GermGuardian AC4825, GermGuardian AC4900CA, GermGuardian AC4300BPTCA and GermGuardian CDAP4500BCA, you will have a 3-year warranty.
The GermGuardian AC4825 is a good-to-go air purifier with a classic 3-in-1 air cleaning system from Guardian Technologies. This air purifier is small and light, weighing only 7 pounds, but it has enough power to keep you healthy in a room the size of a double-priced air purifier. Together with the GermGuardian AC5250PT, the GermGuardian AC4825 is the strategic ace of this brand in the low-range market.
