Their name even reaches outside of border of the U.S, with 17 subsidiaries worldwide.

AeraMax 100 Price

The international name of AeraMax 100 is AeraMax DX5.

If this brand has the AeraMax Pro III and AeraMax Pro IV, were designed to mix with air purifier royalty, then the lineup of AeraMax 100, AeraMax 200 and AeraMax 300 is down there scrapping with the low and middle classes. You could say that the main purpose of these devices to provide a sufficient affordable choice for the consumers.

Just like any starter for a low-ranger, AeraMax 100 attempts to decrease the size and fan power from higher up the range. But you can expect more, and only from the AeraMax 100. It has the unbelievable Smart Sensor function to trick people think that they are having a luxury air purifier. In an era that your bedroom is covered mostly by the best Levoit LV-H132, an improvement like this AeraMax 100 is truly favorable.

Add to that, we have some fancy features like Aera+ Mode or PlasmaTrue Technology, which I am happy to explain thoroughly in the additional features part. And the AeraMax 100 starts to look a lot like a middleweight contender for the new edge-to-edge generation.

For the official price, AeraMax 100 will cost you $129. However, you will always be guaranteed to find a better deal from our website, as low as $94. You can grab this deal right below.

The AeraMax 100 is how Fellowes fires back at others in low-range segment, like Blue Pure 411, GermGuardian AC4825, GermGuardian AC5000, PureZone and Honeywell HPA060. While it’s a solid effort from one of the world’s biggest manufacturers, however, there are a few notable shortfalls that might make you question whether it truly provides value for money.

AeraMax 100 Design and Size

Quick comparison for design of AeraMax 100 with AeraMax 200 and AeraMax 300.

  AeraMax 100/90/DX5 AeraMax 200/190/DX55 AeraMax 300/290/DX95
Height (inches) 27.25 20.5 25
Width (inches) 7.25 13 16
Depth (inches) 8.5 7 8
Weight (lbs) 9.24 9.9 13.5

Just like the rest of the air purifier world, AeraMax has switched to a thin-and-tall design philosophy. The AeraMax 100 has a relatively small base, minimal but necessary control panel, and a quite unique air flow system concept that doubles the direction of the fresh air to the users.

In keeping with the obvious debt it owes to the GermGuardian Ac5250PT, the AeraMax 100 is not just a typical tower air purifier. It stands as high as 27.25 inches, which is slightly shorter than the 28-inch air purifier of Guardian Technologies. But with 7.25 inches in width and 8.5 inches in depth, the AeraMax 100 is more like a 3D rectangle, rather than the typical cylinder-shape of the air purifiers in this price range.

Though the air flow system concept in this AeraMax 100 is back-to-front, we can see that Fellowes has taken a fresh approach to design with the new air outlet grill. It is behind the front plate, so this AeraMax 100 can divide the direction of the output fresh air into 2. For the advantage, it can accelerate the air purification process. But on the negative side, this AeraMax 100 can’t direct the fresh air into the users, just like how the GermGuardian Ac4825, GermGuardian AC4300 or PureZone Elite can do.

Moreover, you can see the control panel of this AeraMax 100 on front.

AeraMax 100, just like any air purifiers in this family, comes with 2 different color options. The AeraMax 100 is also the name of the White version. To look for the Black version, you should search for AeraMax 90, or you can check the price below.

aeramax 100 review

Both AeraMax 100 and AeraMax 90 are light enough to pick up and move around your home, with the weight of 9.24 lbs.

For UK readers, you can search for the AeraMax Baby DB5, which has similar power to the AeraMax 100 and is currently on sale.

AeraMax 100 Filters

As the most important factor to decide the performance of one air purifier, commonly, we don’t expect much from a low-range, under $100 air purifier to have the best air filters. But still, there are a few brands that can keep up with the amazing air filtration system. AeraMax 100 could be the king of the most affordable air purifiers, with a 4-stage air cleaning system as below.

  1. Activated Carbon Filter – First, AeraMax 100 uses an Activated Carbon filter to act as a pre-filter, and can capture both large particles and household odors, pet odors, cooking odor and cigarette smoke.
  2. True HEPA filter – Next, all airborne contaminants must rest in the True HEPA filter of this air purifier, with a high efficiency of trapping 99.97% of any particles as small as 0.3 microns like pollen, ragweed and other allergens, viruses, germs, dust mites, mold spores, and pet dander.
  3. AeraSafe Antimicrobial Treatment – The built-in protection right in the surface of its True HEPA filter, to prevent the growth of odor-causing bacteria, mildew, and fungi.
  4. PlasmaTrue Technology – This is one kind of ionizer, which creates an ionized field to help safely remove airborne pollutants. Can be switched on/off.

Of course, the AeraMax 100 doesn’t use the latest version of Fellowes True HEPA filter, but it is still protected by the antimicrobial treatment, and can last for 1 year without replacing. To be fair, this True HEPA filter is the best thing you could get for only $100, and the only with an expensive treatment on. Others like GermGuardian AC4825 and Levoit LV-H132 can only last for 6 to 8 months at best.

Today, the trend of budget air purifier is adding another kind of filtration, to compensate the lower capability of the small-sized True HEPA filter. GermGuardian is famous for their UV-C light bulb, while the Levoit brings a poly pre-filter. In this AeraMax 100, Fellowes uses an ionizer, in the name of PlasmaTrue, to guarantee the capture of any air pollutants on the physical True HEPA filter. It creates an ionized field, where the contaminants will be then electrostatically attracted to the filter.

There are many studies show that the ionizer is a main reason for emitting ozone, which can irritate asthma and many other breathing issues. The AeraMax 100 is certified both by the California Air Resources Board (CARB) and Asthma and Allergy Foundation of America, to comply the standard ozone emission concentration of less than 0.05 ppm. You still can turn off the PlasmaTrue function anytime you like.

To test the performance of this AeraMax 100, I used the very usual test that have been used on things like Blue Pure 411, Honeywell HPA020B or GermGuardian AC5000. In a room of 100 square feet with full smoke of pollutants, I run the AeraMax 100 in 1 hour to test its efficiency. I also added the PureZone, Levoit Vista 200 and VEVA 8000 Elite Pro to compare with the AeraMax 100. With a weaker fan power, the AeraMax 100 can only score the efficiency of 99.8% for trapping any particles down to 0.3 microns.

aeramax 100 review

The filter of AeraMax 100 has the longest lifetime in the world of budget air purifiers, and it will only cost you $37. You can also find the deal that will reduce the air filter cost to about $28, and I believe this is an amazing price for a fine filter. To avoid mistake, you should follow our deal below for the filter replacement.

AeraMax 100 Room Coverage

Quick comparison for room coverage of AeraMax 100 with AeraMax 200 and AeraMax 300.

  AeraMax 100/90/DX5 AeraMax 200/190/DX55 AeraMax 300/290/DX95
Room coverage (sq ft) 100 400 600
ACH 3X 5X 5X
CADR – Dust (cfm) 65 129 196
CADR – Pollen(cfm)  68 126 191
CADR – Smoke (cfm)  75 124 188

AeraMax 100 is an air purifier for small bedroom, so I can easily guess the power of its fan to be quite weak. In real-world use, the AeraMax 100 is exactly for a room of 100 square feet.

The ACH of AeraMax 100 is 3X. For a small-sized air purifier, the AeraMax 100 is quite better than others, and can exchange the air 3 times per hour.

The CADR of AeraMax 100 is 65 Dust/ 68 Smoke/ 75 Pollen (cfm). It is lower than both the GermGuardian AC4825 and Blue Pure 411, and I believe the AeraMax 100 will take lots of time to clean your room.

AeraMax 100 Sound

AeraMax 100 is not really great at running quietly. The PlasmaTrue function is definitely a culprit, as the crackling noise of the ions continues to make many people feel annoying. If you run this air purifier on lowest setting, the default noise level will be 35 decibels (db), which is still lower than the library noise level. However, you can’t hide away the crackling noise, right?

If you don’t really in need of the maximum performance, I recommend to turn off the PlasmaTrue function. This is the only way you can keep your air purifier at the normal status that fits the quiet places the most.

AeraMax 100 Power Consumption

One of our most FAQs is “Do air purifiers use a lot of energy?” In fact, air purifier must be used for a long time to be efficient. And power consumption is one important criteria to review if this air purifier is good or not.

As a compact air purifier, the AeraMax 100 consumes quite many energy. The rated power at the lowest setting is about 37 watts, which is 1.5 times higher than the Levoit LV-H132. If you switch to the highest fan speed, AeraMax 100 will consume 51 watts. To reduce the power consumption, you really need to turn on the Smart Sensor of this air purifier on.

If you invest in AeraMax 100, you need to pay for about $13 to $18 annually, with about 8 hours of use per day.

AeraMax 100 Additional Features

With this first generation of notched air purifiers, one of the first questions I asked is how well the additional features actually is. As you can see, the additional features is the selling point that many brands is trying to talk about their budget air purifiers.

The Smart Sensor, named AeraSmart, is quite precise in my test. Since this is one rare air purifier with a built-in Smart Sensor function, you will be happy with its accuracy. And if you turn it on, it will automatically change the fan speed to match the current indoor air quality. It is really important in saving your energy and prolonging the air filter’s life.

AeraMax 100 has an unique Aera+ Mode, which is the only button that you need to increase the air turnover rate, and clean your room much faster. This function is somehow like the Turbo Mode from Honeywell HPA100, or Quick Clean Mode in Sharp FP-F50UW or Sharp FP-F60UW.

You will also have one filter replacement indicator, to tell you exactly when you need to change your True HEPA filter.
