Besides, you may check out the most popular Germguardian air purifier reviews and there you will find different models, sizes of air purifiers.
Moreover, the AC4825 is also slim and sleek, it is a bit smaller than GermGuardian AC5250PT. The height is 22 inches. Despite the 22-inch in height, the design of this air purifier is overall the same with the bigger brother, GermGuardian AC5250PT.
By the way, the best place for this air purifier is to keep it on the floor, it fits very well in the corner. And don’t forget to leave space (at least 1 foot) between the wall and air purifier because of the air inlet and outlet.
Filtration
GermGuardian AC4825 features a 3-in-1 air purifying system with these air filters as below:
Pre-filter: Combining with the Activated Carbon filter, It absorbs cooking smells, cigarette odor, and some VOCs. Besides, this AC4825 is a heavy-duty odor absorber as the filter is deeper. So, you can choose this air purifier if your primary concern is to remove odor from your room.
True HEPA filter: The primary filter is a true HEPA filter that traps 99.97% of household dust, dust mites, pollen, mold spores smoke particles of 0.3 microns in diameter.
UV-C Light: The third and final step in the purification process is an optional UV-C ionizing beam. By using this process germguardian AC4825 can kill airborne bacteria, viruses, and mold spores.
Filter replacement
The filter needs to be replaced every 6-8 months depending on use. Also thanks to the smaller size, this true HEPA filer of AC4825 is also lower in cost compared to the other 28 inches’ air purifiers from this brand.
CADR ratings
The Clean Air Delivery Rate (CADR) of GermGuardian AC4825 is 118 Dust/ 108 Smoke/ 125 pollen (cfm), which is looking great for the small to medium-sized room.
The CADR is verified by AHAM, and you can rely on it without any doubt!
Air change per hour
This air device can purify 4 times every hour in a 167 square feet room
Although, this air AC4825 is good at removing various types of pollutants from your home but if you have too many allergy problems then you can’t consider this AC4825.
Because this device does not have a good ACH for allergy removal. So if your primary concern is allergy removing then go for a high ACH air purifier like levoit core 300 or levoit p350.
For an allergy sufferer, the recommended air exchange is at least 5 per hour, and you need at least 8 ACH for smoke removal.
Room coverage
Here you are getting 167 square feet coverage with this germguardian ac4825 air purifier which looks good and this room coverage is also better than some of the expensive air purifiers from this brand.
Like germguardian ac4300bptca’s coverage area is only 153 square feet which is smaller than AC4825 so you will have better room coverage at a lower price.
Noise level
Some of the air purifiers in the market produce high noise which is really disturbing.
Besides, if you are a light sleeper, then the noise level of the air purifier can be a significant disadvantage for you.
So, that is why you need to judge an air purifier before you pick one up from the store. Now let’s get to know how much noise is produced in our AC4825.
The germ guardian AC4825 comes with 3 fan speeds like other low-range air purifiers. And when it runs at the lowest setting then the noise level reaches 40db which is common for an air purifier.
Besides, if you run it at the highest setting then its noise level reaches as far as 55db which looks a little bit noisy. So, always set the device at the lowest setting when you go for sleep.
Control panel

The control panel is conveniently located on the top of the device and also very convenient to use.
With this control panel, you will get one on/off button, one fan speed switch one UV-light button, and a LED filter replacement indicator.
But it does not have some necessary features like smart sensors to monitor the quality of the room’s air. so you have to manually choose between three available fan speeds.
Power consumption
The power consumption of germguardian ac4825 is 53 watts which looks a little bit higher than many other energy-saving air purifiers in the market, like the Levoit LV H132, Blueair 411, Levoit vista 200. For running an AC4825 regularly you need to pay approximately $19 per year.
