GermGuardian GG1000 Vs GG1100: Design

The GermGuardian GG1000 and the GermGuardian GG1100 feature pluggable designs. They are also both compactly designed; almost the same height. They both do not have filters which if present would have needed to be replaced periodically. Their filtration system is based on the UV-C light bulb onboard. That UV-C light bulb is a model LB1000 and every 12 months it needs to be replaced. The glow from the UV-C light turns out to be a design element that needs to be tweaked. This is because it is unpleasant in some circumstances. Both the GermGuardian GG1000 and the GermGuardian GG1100 are designed elegantly.

The build material is sleek and easy to clean. However, the build material is not as robust since if it drops it can easily get damaged. It can crack or shatter. That is why one would have to exercise caution when handling so that it does not fall. The GermGuardian GG1000 and the GermGuardian GG1100 differ when it comes to their general shapes. The GermGuardian GG1000 is mostly cylindrical. The GermGuardian GG1100 kind of has a cuboid shape.

One of its downsides is that it does not effectively filter air from particulates. Thus when it comes to the air purifier function, the GermGuardian GG1000 is not that good. The GermGuardian GG1000 is not that effective at deodorizing the air. The GermGuardian CG1000 is noisy for most people. That is why it ranks quite low when it comes to noise level amongst most users. This ends up limiting where one can use the GermGuardian GG1000. For example, it may not be convenient to place it in rooms where people normally are. The noise emanates from the fan when in operation. As for odor elimination, quite a number of users cite ineffectiveness in providing that function. This may be influenced by user-related dynamics in some cases. However, the general consensus is that it mostly does not fully get rid of odors.

Cons Of GermGuardian GG1100

One of the downsides of the GermGuardian GG1100 is the UV-C light. This is also an issue that applies to the GermGuardian GG1000. The light tends to glow way too brightly. This can limit again where you can use the GermGuardian GG1100. For instance, it may not be best to place in a bedroom at night. The glowing light will create an ambience that disrupts sleep. Plus the bright glow will draw outside attention to the bedroom. The brightness of the light poses leakage concerns and may drive up the electricity bill. The GermGuardian GG1100 tends to be less effective when placed in large rooms. Its effectiveness is mainly confined to small spaces or rooms.

Factors To Consider When Buying Air Sanitizers (Or Purifiers)

When looking to buy an air purifier you have to consider some factors. Due to advancements in technology there are now widespread applications of smart technology. It may be preferable to purchase an air purifier that works on smart technology. The type of space or room you intend to use the air purifier in matters. For instance, some air purifiers are not effective in large rooms. Thus you have to ascertain the capability of the air purifier to handle your target spaces or rooms. You have to factor in the filtration system of the air sanitizer in question. There are different filtration systems e.g. HEPA and UV, amongst others. Air filtration consideration is pertinent especially to the health of people around.

For instance, air filtration systems that emit ozone can be detrimental to people with respiratory conditions. That is why UV filtration systems would be preferable because they do not produce ozone. Another thing to consider is the air changes per hour (ACH) rating. An air sanitizer with a high ACH rating is most preferable. The other factor to consider is energy consumption. This is particularly when you will be using a number of units. That can significantly affect your electricity bill. This is especially so if you keep the units running round the clock. You must also consider the noise level of the air purifier in question. A noisy one may be disruptive and will fail to serve its purpose as you will tend to keep it off.

Frequently Asked Questions (FAQs)

How long after plugging in are germs removed from the room?

This depends on the size of the room. As an example, it would take just over an hour for a room measuring 8 feet × 8 feet × 8 feet. Bear in mind that the UV-C air sanitizer has to cycle through it all the air in a room. Only then would it have removed the germs. However, you must understand that it only cleans the air. As in, it removes or kills the air borne germs; not the ones attached to surfaces. You must also know that opening doors or windows has an adverse effect on the performance of the UV-C air sanitizer.

Is it okay to leave it plugged in all the time and is it necessary to do so?

It is okay to do so though it may not be necessary. User experiences differ on how long it lasts when it is always plugged in. It is wise to only keep it plugged in when absolutely necessary. Otherwise periodically plugging it in may be the best approach.

If I do not have wall sockets, with a power strip on the floor, will it still work for me?

Though it would work but it will not be efficient. It is best for it to be wall mounted for better airflow. That is why you would have to figure out a way to probably fasten the power strip to the wall. That way the UV-C air sanitizer can operate most efficiently.

With the fan constantly running, how much does each unit affect the electric bill?

This depends on a couple of variables. For instance, the wattage is one. It also depends on how long you have it running. With the fan and lamp on and the unit running round the clock you can consume just over 3 kWh of electricity in a month. Thus when it is only one UV-C air sanitizer the electricity cost is almost negligible. A substantial cost will only occur when you have several units all running round the clock.

How many square feet do these plug-in sanitizers clean and purify air and do they emit ozone?

Plug-in sanitizers will cover up to 56 square feet. They do not emit ozone.

Do air purifiers remove dust?

Yes but to a certain degree. It depends on the filtration system at play. Plus you must remember that air purifiers deal with air borne particles. This means they may not be able to remove dust that is on surfaces. The most effective filtration system that can remove the most air borne dust is the HEPA.


Choosing between the GermGuardian GG1000 and the GermGuardian GG1100 comes down to preferences. These two air purifiers are mostly similar. They are even priced the same.
