Similarly, this air purifier weighs 13 pounds with 23.46 inches in height, making it easy to carry around your home from one room to the other without much heavy lifting.

Positive and Negative Aspects to Help Guide You

When deciding on buying, the very first thing you need to pay attention to is the benefits or pros with which the air purifier comes.

  • A requirement to replace its filter every 6-8 months, adding more cost to your already purchased air purifier

Is It The Best Germ Guardian Air Purifier? My Final Verdict

If you ask me whether this air purifier with model number AC5109W is worth buying, my decision would be in favor of it due to the following reasons:

  • 6-in-1 Air Purifier: Many air purifiers have a 3-stage purification system to clean the air inside your home or room. However, this Germ Guardian purifier circulates the air through 6 stages, including HEPA filters and UV-C light equipped with titanium dioxide, to filter out pollutants.
  • Best For Large Area Rooms: If your room is stretched over 394 sq. feet, this air purifier standing of 23-inches in height is best to purify the air throughout the room.
  • 4-Speed Options: I call it the best Germ Guardian air purifier because of its equipment with 4 different speed options to adjust air optimization levels.
  • No Sleep Issues: UV-C light does not pass out of the air purifier and does not create any disturbance to sleep.
  • Ionizer That Does Not Release Ozone: Air ionization installed in the purifier generates negatively charged particles that attract germs from the atmosphere. However, there are chances that many ozone molecules may also be produced during the purification process, which isn’t the case here. Hence, you can be assured that there will be little to no ozone molecules in your room’s atmosphere.
