It’s compact, and minimalistic design makes it the best air purifier for the house. It is designed in a way that it can be placed in any part of your room or office. It is also extremely light in weight that makes it possible to carry it around. If you are looking for an air purifier which is good for medium and small sized rooms, then you need to look elsewhere. GemGuardian AC4100 works perfectly in small rooms, but in large and medium rooms its power is lost.

Three stage filtration

The GermGuardian AC4100 has a three-stage filtration system that amazingly removes allergens and household odors. The air purifier has a proper filtration process. The first step is the filtration process; the dirty air passes through the machine that further activates charcoal pre-filter. The pre-filter traps airborne bacteria and helps in getting rid of the bad odor, dust, and smoke particles.

The next step is where the air is passed through HEPA filter. HEPA filter traps 99.97 percent of air particles as small as .3 microns. These particles usually contain contaminants that trigger asthma and allergies.

The third and the last stage is treated by the UV-C light mechanism. This mechanism is a modern way of getting rid of common germs and dust. It efficiently penetrates bacteria and many thin-walled viruses that cause diseases such as pneumonia, tuberculosis or bronchitis. It putrefies odor particles emerge from smoke or pets. Because of that, it is highly recommended as an air purifier which is good for pets, cooking and smoking.

3 Speeds and incredibly silent

The Germ Guardian air purifier has startling three various fan speed options. If you want no noise and satisfactory results, you can set the machine at low setting. For proper operation and healthy air circulation set the parameters at medium. Whereas if you want optimal results and best air circulation, set the fan at high option. The high setting emits a lot of noise that is quite disturbing for many people, but if you keep the low settings on you will not even know the air purifier is working.

The GermGuardian AC4100 is considered as the best air purifier because of its efficiency and powerful operation. If you are tired of noisy air purifiers, then this is the best option for you because it is incredibly silent. You can place it in your office and work peacefully without realizing it’s there. It’s sleek, and compact design makes it possible to carry it around. It requires small space in your room. The low purchase price makes it even more desirable.

Although it works amazingly in small places, it is not recommended for larger areas. It only eliminates household odors and does not work for the heavy smell.

Filters Replacement

GemGuardian uses same HEPA filter for various GemGuardian Air purifying models. HEPA filter comes with pre-filter which means that once you replace filter air in the room will be filtered with more efficiency than before with a dirty filter. The charcoal filter is also included, and that means that removing bad smells will work same as it was working once you bought the original air purifier. GemGuardian HEPA filters are affordable, but you need to know that these filters are small because this air purifying model is small and because of that price for a filter is low.
