I am sure that you are also aiming for a better quality environment for your family, and that you would be bothered knowing that potentially harmful microbes could be polluting the air in your home.

We don’t want your family to get sick, which is is why we are offering you the ultimate solution to this problem!

We’re talking about an air purifier that will clean and refresh your surroundings: the GermGuardian AC4100 3 in 1 Air Purifier with HEPA Filter. The speedy tabletop tower option is less costly compared to the 4 in 1 GermGuardian model, making it great for a tight household budget.

Product Description:

This  has the power of UV-C light that swiftly kills airborne germs that may cause a threat to your family’s health.

GermGuardian AC4100 has HEPA fresh filters that can suck up to 99.97% of airborne molecules, providing fresher air to a room up to 200 square feet in size. With its True HEPA carbon air filters, it also has the power to remove the odor from your home’s air as  a tabletop filter.


The GermGuardian AC4100 has 3 filtration processes: carbon filters, HEPA filters, and UV-C light.

Carbon filtration, or charcoal/photocatalytic filtration, is the first process, which removes foul odors caused by cooking in the  kitchen, smelly laundry, pet waste, garbage, and so on. It effectively removes all the bad odor and makes your home environment fresher. Be sure to check the replacement filter along with product details and the price of the air purifier. The 3 in 1 HEPA GermGuardian also has excellent performance compared to the GermGuardian 4 in 1.

Next is HEPA air filtration, which manages to capture the smallest airborne molecules—including 99% of pollutants in the air of your home, namely mold spores, dust, pollen, pet hairs, and more. While checking the price, be sure to check the GermGuardian ac4100 model reviews and feedback on the True HEPA filter.

The last stage is where the UV-C light takes place. It acts a sanitizer for the air that effectively eradicates 99.7% of airborne particles like bacteria and germs, including viruses that can be harmful to your family’s health. It does not just kill germs and viruses; it also destroys the DNA of these pests so that they cannot spread any further throughout your home. This HEPA air purifier requires changing its True HEPA filter every 6-8 monthsor about twice a yearfor maximum efficiency. The UV light and powerful filter system make this the best tabletop air purifier on the market.

GermGuardian AC4100 has 3 speed controls for your filtration needs, all thanks to the HEPA air purifier. Its lowest speed runs peacefully quiet. The next speed is a bit faster, but not much louder. The highest speed is not what we would call whisper quiet because it produces some sound, but it is not too abrasive, and still does its job of purifying your surroundings.


The HEPA filter is perfectly built in a classic design that really stands out. It comes with a plastic case and a round switch in front that conveniently enables you to adjust the the fan’s speed. It only offers one simple, black design that fits well into any room’s aesthetics.. It works well in small spaces where chances of asthma being triggered and CADR dust is high.

It is small and lightweight, so you can just put it on the coffee table in your living room or even on your bedside table. It has dimensions of 7.5 x 6.5 x 11 inches and weighs just 4.85 lbs.

Its portability allows you to take it to anywhere you want. Another amazing feature of its design is that it comes with a 6-foot cord, which makes it easier to place if a room is short on convenient outlets.

There are only a few downsides to consider before buying this product.

Not ENERGY STAR Qualified

It is not yet ENERGY STAR certified. It is not yet been checked against EPA standards for quality of air purification.

Not the best for large rooms

It is not the most suitable purifier for larger rooms, as it is designed to clean the air in smaller areas. If you have a larger area to cover, we recommend other products from GermGuardian.


Because of its short warranty—1 year—many are doubtful of its durability, and opt for products with longer warranties.

Despite the downsides, it is still rated as one of the most highly efficient air purifiers on the market. With its 3-in-1 feature, you are guaranteed to have air cleansed of pollutants like pet dander, dust, and allergens.
