When GermGuardian GG1000 pluggable UV-C sanitizer was first launched, we touted this as the innovative small appliances of the year. It is the perfect compact UV sanitizer that cleans the air simply by plugging it into a wall outlet. At around 1.13 pounds weight, 3.2 inches width, and 7.5 inches height, it is a space-saver that takes up very little of your interior space. If you are a frequent traveler, GermGuardian GG1000 can easily be packed into your backpack even on a short getaway.

One of the most interesting aspects of GermGuardian GG1000 is a unique hourglass design. It looks elegant and premium with metallic touch despite it is made out of plastic. Build quality is good with no signs of byproduct leakage detected. The thin air inlet is located at the bottom front with an air outlet at the usual top spot for better distribution. You will not find any complication controls here other as GG1000 is a basic plug and play model.

Moving to reliability, GermGuardian GG1000 UV-C Sanitizer comes with a 1-year limited warranty which is nothing spectacular, but at least it is still US-based tech support rather than a third-party country. To ensure the filter-free UV sanitizer is in tip-top condition, do not place it under direct sunlight or near flammable items like insecticides. Also, make sure the sofa or bed is not impeding the airflow distribution.

Airflow, Coverage, And CADR

As a pluggable air purifier & sanitizer, GermGuardian GG1000 airflow distribution is rather limited. The 56 square feet recommended room size can only cover a small area. Adding the lack of a big motor fan to draw airborne pollutants in, you will need multiple units to purify the air in a large room. CADR is not available as the UV sanitizer does not come with a filter required for proper testing.

^ Replacement filters/ estimated cost
For less than 40 dollars, GermGuardian GG1000 Pluggable Air Sanitizer is very affordable and comes with a standard UV light bulb. You do have to replace the light bulb every 6 to 12 months but the replacement cost is quite reasonable. Being a pluggable filterless air purifier, most people will compare this with the newer GG1100 version. So if you don't mind the older design, GG1000 is cheaper and works exactly like the newer version.
As alluded earlier, GermGuardian GG1000 is in the market for quite some time so it might not be that easy to track this model. While you will have no issue purchasing it from the official channel or Amazon, local retailers or malls like Walmart, Costco, Home Depot may not carry the stock. In any case, we always recommend buying it online to enjoy the best deal, free shipping, and 30 days return policy.

Newer version that costs around 10 bucks more but gains an updated design and black color option. Also come with a USB charging port to charge your electrical devices.

Clarifion Negative Ion Generator GL-139

A pluggable alternative that uses a negative ion generator instead of UV-light to clean the air. Absolutely no running cost but generally less effective compared with UV technology.
