GermGuardian AC4825 Air Purifiers’ biggest selling point is that they save you from becoming sick thanks to airborne particles. This comes at a cost though, and that cost is the need to replace two filters instead of one. But can you put a price on your health? Check out our best air purifier under 100 list for more!

Performance

The GermGuardian Air Purifier offers a three-stage filtration system. The first layer, the pre-filter, and activated carbon filter, catches all the large particles like smoke and pet dander. Second, the air goes through the true HEPA Filter and catches smaller particles like mold spores. Last, the UV C Light kills any airborne bacteria that cause sickness or allergies. This leaves you with a room of clean air. Check out the LEVOIT LV-H132 Air Purifier Review if you’re looking for three-stage filtration air quality in a unit that’s not so large.

Design

The GermGuardian Air Cleaning System’s controls, including the fan speed settings, are located at the top of the unit. Note that, because of the UV Light, filter replacement will not be limited to HEPA filters, but UV C filter replacement too. If you review GermGuardian AC4825’s dual-filter needs and decide it’s not for you, consider the KOIOS Upgraded Purifier Filtration Purifier White as a healthy replacement. Finally, the GermGuardian is about 22” in height and weighs around seven pounds. Not the smallest or lightest, but still portable enough to bring anywhere.

Value

The GermGuardian Air Filtration system provides medium-sized rooms with a good amount of cleaning, as the Envion Therapure does. It’s rated for a room size of 167 square feet, which is the largest we’ve seen thus far. The noise level isn’t particularly high, but still the highest among other air purifiers in its class. At the lowest setting, it still reaches about 40 dB. Consider the GermGuardian GG1000 Pluggable Deodorizer Guardian if you want something quieter and, as a bonus, smaller. It retails for $120.00, which is a little steep, but gives you superior room coverage and air quality.

GermGuardian AC4825 Wrap Up

The people of Guardian Technologies have designed an effective air purifier with their AC4825. It provides excellent room coverage and kills airborne bacteria so you won’t get sick. It is rather noisy, so it’s not best to have it on when you’re trying to sleep. An easy solution? Have the unit purify while you’re away so you can come home to a clean air home after a long day!
