GermGuardian AC4825 Review

The GermGuardian AC4825 is a simple tower-design air purifier that’s easy to use and has great air cleaning abilities. What it lacks in fancy features (when compared to more expensive models), it makes up for in advanced air purification. Overall, it’s a great value and is perfect for small spaces.

We’ll get into the full details in the next section of our GermGuardian AC4825 review, but the UV-C light strip is worth a quick mention.

A blue light shines in a small strip around the top of the air purifier, which makes it look like a modern and sophisticated machine.

While this light won’t cause you any harm, it does add a unique feature to the air purifier that lets you know that the UV-C function is working. It can also double as a night light if you’re using this air purifier in a bedroom.

Next, we’ll describe how each of the air cleaning filters works.

Filter Types

Photo of GermGuardian AC4825 FiltersThe GermGuardian air purifier AC4825 has a powerful 3-in-1 filtration system that helps it remove the widest range of indoor contaminants.

Those filtering types include:

  • Activated Carbon Pre-filter – This does double duty:
    1. Traps the larger particles so the True HEPA filter lasts as long as possible
    2. Reduces household odors, smoke, and chemical vapors in the air (i.e. pet smells, tobacco smoke, cooking odors, and volatile organic compounds).
  • True HEPA Filter – This filter has the ability to remove 99.97% of pollutants as small as 0.3 microns in size. This includes dust, dust mite waste, pollen, allergens, mold spores, pet dander, and some forms of bacteria.
  • UV-C Light – This is where this air purifier really outshines the competitors. The UV-C light destroys harmful microorganisms and pathogens. Viruses such as staph, the flu, and rhinovirus are taken out of your air to reduce the chances of you or your family getting sick. The air purifier also contains Titanium Dioxide to further protect you against volatile organic compounds that might be in the air.

GermGuardian AC4825 CADR Rating

The CADR rating on an air purifier is a crucial stat. And the GermGuardian AC4825 has excellent numbers.

To prove that their machines work hard to purify the air, many manufacturers will have them independently tested by the Association of Home Appliance Manufacturers (AHAM) to get a Clean Air Delivery Rate Rating (CADR).

The purpose of these tests is to determine how well the appliance can filter out pollen, tobacco smoke, and dust from the air.

To be considered “efficient,” the machine needs to have at least a 2/3 rating for each number when compared to how many square feet it covers.

The CADR ratings for the GermGuardian AC4825 is more than adequate:

  • Dust: 118
  • Smoke: 108
  • Pollen: 125

For the size of the GermGuardian AC4825, these are good numbers, and you can expect it to get rid of many harmful elements that might be in your air (allergens, bacteria, and viruses) as well as reduce unpleasant odors.

GermGuardian AC4825 ACH Rating

The ACH rating is another important feature to look for on any air purifier.

This refers to the “Air Changes per Hour”, which is how long it takes for the air purifier to cycle the air in a room.

The GermGuardian AC4825 air purifier has an ACH rating of 4X.

For rooms that are up to 167 sq. ft. in size, this air purifier will exchange the full volume of air 4 times an hour.

That means every 15 minutes your air is getting recycled with cleaner, fresher air while this machine is running. Over time, up to 99.97% of contaminants get be stripped from the air around you.
