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 received well here. Knowing the potential of the AC5000E device, Guardian Technologies invented a 22-inch version of this successful air purifier and reduce the cost even much lower. 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 flagships of this brand in 2019 are the GermGuardian AC9400W and GermGuardian AC9200WCA. But if you are looking for a Smart air purifier, you should search for either the GermGuardian CDAP5500BCA or GermGuardian CDAP4500BCA.
In Breathe Quality, we have reviewed all air purifiers under these sections. Also, we guarantee that:
- We do give honest reviews (both pros and cons) so anyone will guarantee to have the wisest choices.
- We do not (and never) exaggerate one product just to let you click the links and buy that product blindly.

- 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 their 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 Design and Size
Notice that you can have the White version of this air purifier, under the name of GermGuardian AC4825W. Our testing model is a Black version, but due to the Guardian Technologies’s manual, both air purifiers serve the same specifications. So if you are looking for a GermGuardian AC4825W Review, you can also read our today review.
One of the first things you notice when you have GermGuardian AC4825 in your home is that despite the 22-inch in height, the design of this air purifier is overall the same with the bigger brother, GermGuardian AC5000.
Follow this design language, this 22-inch air purifier is ready with an air output grill from the front and an intake grill from the back. This classic air flow is the unique feature of GermGuardian air purifier, to increase the efficiency of its fan.
Also, at the top of GermGuardian AC4825, you will find a twin control panel with 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, GermGuardian AC4825 air purifier is even lighter than the CDAP4500BCA which weighs 9.45 lbs. With a relatively small size, GermGuardian AC4825 is compact and therefore easy to bring anywhere in your home.

GermGuardian AC4825 Filters
GermGuardian AC4825 features a 3-in-1 air cleaning system with these air filters as below:
- 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 from 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, GermGuardian AC4825E can kill airborne bacteria, viruses and mold spores.
GermGuardian AC4825 is powered by a same True HEPA filter from Guardian Technologies brand, the FLT 4825 filter-B HEPA to help capture the tiniest contaminant particles as small as 0.3 microns including of dust, dust mites, pollen, pet hair, pet dander and any other allergens. Just like the bigger version – GermGuardian AC5000, GermGuardian AC4825 also has one pre-filter with Activated Carbon layer attached to reduce the smoke and odors. Apart from these typical filter layers, 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 Honeywell HPA020B and GermGuardian AC4150. They are all in the same test conditions, a room of 100 square feet and duration of 1 hour. With double the standard room size, Honeywell HPA020B fell to only 99.7%, while the GermGuardian AC4825E is still 99.5% for capturing as small as 0.3 microns particles. The GermGuardian AC4150 has the lowest performance, with only 95%.
As usual, you need to change the air filter every 6-8 months base on 24/7 use. Thanks to the smaller size, the filter-B HEPA is also lower cost 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 of featuring an older air filtration process, the CADR rating of this air purifier is even better than the latest portable device of Guardian Technologies – CDAP4500BCA.

GermGuardian AC4825 Sound
Using a same 3 fan speeds like its bigger brother, GermGuardian AC4825’s noise level is better than the modern devices which commonly comes with 5 fan speeds. A smaller size also helps reduce the fan size, and as a result, reduce the noise, but only on highest fan speed.
At the lowest setting, the noise level of GermGuardian AC4825 is still 40 decibels, which is higher than most of the normal air purifiers in the market. For example, the AeraMax 300 is only 35 decibels, the SilverOnyx can be as low as 25 decibels, or the Winix 5300-2 with only 28 decibels.
But when you switch to the highest setting, the noise level of GermGuardian AC4825 is only 55 decibels (db), which is lower than the common 60 db of GermGuardian AC5000 or GermGuardian AC5350B. This is still near the noise level of the public restaurant, or an air conditioning unit at 100 feet. But still, better is better.
However, the noise level of this air purifier didn’t fare too well in quiet places, you will still notice a clear sound, especially when running at the highest setting. That’s why, we believe that GermGuardian AC4825 is still not suitable for your office or bedroom.

GermGuardian AC4825 Power Consumption
To be one of the best air purifiers, one device must strictly pass our Breathe Quality test after a long time use. Also, one of the most asked questions in Breathe Quality is: “Do air purifiers use a lot of energy?”. We can all agree that power consumption is one important criteria to review if this air purifier is worth your money or not.
Using a 5 watts UV-C bulb, GermGuardian AC4825’s power consumption is about 60 watts. It is still higher than many other energy-saving air purifiers in the market, like the Blue Pure 411, Levoit LV-H132, SilverOnyx or AeraMax 100.
For using a GermGuardian AC4825 8 hours per day, it would cost you up to $22 per year.

GermGuardian AC4825 Additional Features
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. One again, we must remind you that this air purifier is superseded by the latest CDAP4500BCA long ago, so you should not expect much for an under $100 air purifier.
GermGuardian AC4825 Customer Service
There is not much to say about the brilliant support from Guardian Technologies’s customer service. The American brand is providing a very active support for anyone contacting them. They also put the Instruction Manuals online to help you solve the common questions by yourself.

GermGuardian AC4825 is a good-to-go air purifier with a classic 3-in-1 air cleaning system of Guardian Technologies. This air purifier has small size with only 7 lbs in weight, but its power is enough to keep you healthy in a same room size a double-its-price air purifier could do.
