Resembles to other GermGuardian Tower Air Purifier, GermGuardian AC4825 3-in-1 22 inch size is not compact but not overly bulky either. Made with black plastic housing with front air vent, the overall appearance is modern and practical for everyday use. Build quality is good with no no askew parts or filter gaps. Controls is located at top with one dial knob to control on/ off and the 3 fanspeed. With no digital display, timer or any other addon function, GermGuardian AC4825 3-in-1 only comes with passive features like ENERGY STAR rate, Safety certified by Intertek (Nationally Recognized Testing Laboratory) and 3 years warranty.

Airflow effectiveness and purifying coverage

Despite the inclusion of charcoal pre-filter, True HEPA filter and UV-C light, GermGuardian AC4825 3-in-1 is still essentially a tower air purifier so the airflow coverage will fall at a restrained level. Appropriate for small room size like bedroom even though living hall could do with it as well. Moving forward with the purifying capability, GermGuardian AC4825 3-in-1 100+ smoke CADR means it can pull in a good amount of air-borne particles within its radius. The steady airflow delivery rate would take up and halt nearby dust, bacteria or odor from flowing around the home.

Noise level and power consumption

GermGuardian AC4825 3-in-1 noise level is significantly lower due to the silent technology and well enclosed body framework. Virtually no noise at low fan speed, light noise at medium fanspeed and distinct noise at high fanspeed. Compare with other quite similar tower air purifier, you would have no problem with GermGuardian AC4825 3-in-1 produced noise level.

Carrying on with the power usage, not only GermGuardian AC4825 3-in-1 is ENERGY STAR rated, the moderate airflow distribution means it will not hurt your wallet on utility bills even in long-run. Electricity consumption is fairly low across all fanspeed although you do have to manually adjust the speed as Auto mode is not included in the feature. By comparison with other home appliances power consumption, GermGuardian AC4825 3-in-1 monthly electricity usage level is reasonably low.

Final thoughts on GermGuardian AC4825 3-in-1

In short, we love GermGuardian AC4825 3-in-1 low price tag, consistent airflow output and 4-stage filtration.

In conclusion......

  • Inexpensive especially after the online discounted price.
  • Decent but not over the top CADR return for an air purifier of its price range.
  • Use True HEPA filter instead of HEPA-type filter like most tower air purifier.
  • UV-C light is effective in eliminating airborne mold, bacteria, germs and viruses.
  • 3 years warranty.
  • The total annual filter replacement cost is close to the price of a brand new AC4825.

  • Uses a smaller UV-C light compare with AC5000 series.
  • Slightly troublesome to replacing UV-C light as you are require to unscrew 2 screws to pull out the bulb.
  • No timer, Auto mode and air quality display.
