Guardian Technologies is the king of innovative small appliances that can improve our health. No exception with GermGuardian GG1100 Elite UV-C Sanitizer. A compact yet powerful air cleaning device that can provide you with fresh air from any wall outlet. At a mere 0.7 pounds weight, 3.5 inches depth, 6.75 inches width and height, you can place it anywhere in the room without being too obstructive. In fact, you can even pack this 7-inch air sanitizer in your backpack during travel.

As for design, there are 2 color options which are white (GG1100W) and black (GG1100B). The clean white design comes with a glowing circle ring at the front letting you know the device is running. The plastic exterior is well-fitted with no obvious off-gassing detected. The air inlet is located at the sides while the air outlet is at the top to distribute the filtered air further out. Being a pluggable device, it is very easy to use as there are no controls to tinker around with other than the USB port. Find a spot, plug, and leave the UV sanitizer to do its things. Just make sure there is nothing impeding the air ventilation of the device or close to flammable gases like fragrances and insecticides.

As for reliability and durability, GermGuardian GG1100 Elite UV-C Sanitizer comes with a standard 1-year limited warranty with US-based tech support. If there are any manufacturing defects, you can send it to many of the authorized service centers located in the United States.

Let's be realistic in this part. GermGuardian GG1100 Elite is a pluggable, UV-C room air sanitizer so it is designed for small rooms. The 56 square feet coverage is not outstanding but it can still refresh your indoor air. Given its small dimension and budget-friendly price, the airflow output is adequate for most people that require clean, breathable air. No CADR available as GermGuardian GG1100 does not fit the testing criteria.

Filters And Performance

For less than 50 dollars, GermGuardian GG1100 is a good filterless air purifier that you can depend on. Powered by the single UV-C light technology with Titanium Dioxide to reduce volatile organic compounds and kills airborne viruses such as influenza, staph, rhinovirus. The UV-C light will also reduce the growth of germs and microorganisms such as fungi, bacteria, viruses. GermGuardian GG1100 air sanitizer can also reduce odors caused by mold, mildew, pets, cigarettes, food, and a diaper pail. Works great in your office or home e.g. bedroom, kitchen, litter box, bathroom, children’s room, and laundry room. You will breathe better, sleep better, and wake up fully recharged with it by your side.

As with all UV-light products, you should take extra caution when using one. Go through the instructional manual as improper use can lead to cancer, birth defects, and reproductive harm. For California consumers, please read Proposition 65 before making a purchase.

Overall GermGuardian GG1100 Elite UV-C Room Air Sanitizer is excellent in eradicating airborne bacteria and viruses within its area. It does not produce harmful byproducts like ozone that can irritate your lungs. The only thing you have to take note of is the UV lamp life needs replacing every 10 to 12 months depending on use. We recommend replacing the light bulb sooner than later as the germ-killing efficiency will drop after 3,000 hours of use.

Noise And Energy Usage

Being a filterless UV-C Pluggable Air Sanitizer, GermGuardian GG1100 is whisper quiet as there is no gigantic motor fan. You can sleep soundly in the bedroom or place it in the baby room next to the crib without having to worry about noise distraction. The 120 Volt AC, 60 Hertz power output is low so it is safe to leave it running the whole day. The power usage is around the region of $0.4 per month or $4.8 annually with 24 hours of runtime. Your electricity bill will still look healthy even with multiple units of the room air sanitizer. Very likely you will not know its existence after some time.

Older version to GG1100 so cheaper by around $10 bucks. Besides the different exterior designs, everything else is identical so go with this for the lower price point.

Clarifion Negative Ion Generator GL-139

Another compact, wall pluggable model uses a negative ion generator to clean the air rather than UV-light. Less effective against germs but gain zero maintenance cost.
