O ne fact is universally agreed upon – clean air indoors can only be achieved through the use of an air purifier that removes impurities and polluting particles. GermGuardian AC5000E is a great purchase that will manage to remove a wide range of pollutants while staying silent and comfortable.

The slim tower design promotes it for small and narrow places and it is powerful enough to handle medium rooms at high efficiency. It is among the more affordable high-end systems available as well, which is another plus. But let’s not waste time and start discussing the product in-depth to see how it works and what exactly it offers to help you make up your mind.

In its operation, it uses a HEPA filter that successfully handles small particles, a carbon activated filter that tackles irritants and odors, as well as a pre-filter that handles larger-size particles to help boost the operation of the filtering stages that follow.

All 3 filters ensure a CADR of 125+, which is not very much if you compare it to other models. It can best handle rooms up to 180 sq. ft. in size, considering it’s not a very big device. What we like is that it can even be used in rooms where silence is most important, like the bedroom or nursery, as it makes little noise when it runs.

The HEPA filter manages to retain 99.97% of small pollutants, including the common and quite abundant dust, pollen, and pet dander, all smaller than 0.3 microns. These are some of the system’s features:

  • Charcoal pre-filter reduces common household odors created by pets, smoking, cooking, or cleaning product
  • The pre-filter can capture larger particles like lint, pet hair, and other impurities that would otherwise get stuck in the HEPA filter and minimize its durability
  • The sterilization light works with Titanium Dioxide to eliminate microorganisms and mold spores, minimizing the risk of developing asthma, allergies, bronchitis, and other severe respiratory problems

The UV-C light it uses and that helps expand its range of pollutants it can tackle is definitely a standout feature of the system. It lets you choose from 3-speed levels, so you can adjust its operating according to the size of the room and the noise level that provides you comfort.


There are no additional features that would increase its convenience related to performance or energy efficiency. It doesn’t come with a programmable timer or an auto mode that would minimize the operating time and the energy consumption, which would make it even more functional.

One aspect to keep in mind is that filter replacement is required every 6-8 months, which is considerably less often than what most systems ask of users, and presents an added bonus seeing how it implies cheaper maintenance. There is even a special indicator set in place that shows you when the filter or the bulb of the UV-C light need to be replaced so that you won’t accidentally overlook the chore and not benefit from as qualitative of a performance as you could on the system’s part.

There is nothing you could complain about when it comes to design, because it’s elegant, sophisticated, and compact, above all. A great thing is that this unit is Energy Star rated and it will only add 55 watts to your energy bill, so you won’t have to worry about this aspect. The model has been designed with the following:

  • The blue LED light that surrounds the silver detail at the top is the icing on the cake, which completes the stylish design of this 28-inch tall tower purifier
  • It only weighs 9 pounds, so you can easily lift and carry it, especially since it has a carrying handle at the back of the housing
  • The device comes with indicator lights that blink when it’s time to perform the operations

Warranty and Support

It comes with a generous 5-year warranty on parts and labor. However, the lifespan can be extended if you take good care of your unit and you make sure you replace the filter with an original one provided by the manufacturer. You can find all the necessary parts and accessories on their website, as well as free customer support for any question you might have related to the system. Whatever question you have, the support team is able to answer it very fast and efficient. Kiss goodbye to miscommunication and wasted time.


Manufactured by what is universally viewed as one of the leading brands in the business, you are sure to make a smart investment if you acquire it. Through the use of HEPA filtration, it tackles the smallest-size polluting particles in the air, whereas the UV-C light sterilizes the air so that it is safe to breathe, making an immediate difference for the better in the air you breathe as soon as you turn it on. It isn’t costly either, which is a major plus as it makes it affordable for a wider range of customers. Add all of these positive traits to the fact that hefty 5-year backing is provided for it, and you can see why this is a product we back and favor.
