Guardian Technologies is doing a much better impression to take back the lowest range segment of air purifier market, especially since this segment is stormed by devices from Airthereal and Levoit. The GermGuardian AC4200W is the latest budget air purifier, yet it looks like a flagship model. Well, let’s find out in our GermGuardian AC4200 Review.

Other GermGuardian’s Air Purifier Reviews:

GermGuardian AC4200 Price

The GermGuardian AC4200 is a new air purifier with sleek design from newest models of Guardian Technologies, which changes the main color of the lineup to white tone.

What we end up with a compact air purifier with the unmistakable design concept from the flagship GermGuardian AC9400W, being just about one third of the price. Yes, its launching price on Guardian Technologies website is only $129.

Well, this air purifier charges you the same as GermGuardian AC5250PT and GermGuardian AC5300B, while having lower performance. Luckily, I get the best deal from the GermGuardian AC4200W, to reduce the official price point by 40%, to only $76. It is only available for a limited time, so be sure to grab it quickly.

With the new drop in price, the GermGuardian AC4200W is a competent opponent of the well-known Levoit Vista 200 or Airthereal ADH80. Guardian Technologies also offers the GermGuardian AC4825 and GermGuardian AC4900CA at the same price point, with much better performance in sacrifice of classic appearances.

GermGuardian AC4200 Design and Size

The GermGuardian AC4200W bears a striking resemblance to the GermGuardian AC9400W with its cylindrical design and spiral top air grill. You can also find the perforated holes as air inlet in this compact air purifier, covered around for a full 360° air intake.

This is truly a portable air purifier designed for bedroom, as it is only 13.5 inches in height, and 9.2 inches in width. To be precise, it is just only half the size of the tower air purifiers from Guardian Technologies, and more than 8 inches shorter than the popular GermGuardian AC4825. It is suitable to be a tabletop air purifier.

Running the popular bottom-to-top air flow system concept for cylindrical air purifiers, the GermGuardian AC4200 differs itself from any low-end members in the same family. However, for a portable device, the bottom-to-top air flow system concept and 360° air intake can utilize the fan power at maximum.

On top of this air purifier, we can see a simple control panel at the center of the air grill, with only 3 buttons.

GermGuardian AC4200 Filters

As the latest generation of Guardian Technologies’s air purifiers, the GermGuardian AC4200 doesn’t use the UV-C Light anymore. Instead, it runs a simple 2-stage air cleaning system for completely no ozone emission.

  1. Pre-filter – Using the Activated Carbon filter, this layer of air filter can remove most of the large particles of pollutants and reduce odors created from smoke, cooking, and pets.
  2. True HEPA filter – GermGuardian AC4200W makes use of a True HEPA Filter to capture 99.97% of microscopic allergens, dust and mold spores down to 0.3 microns in size.

Being the compact air purifier, mostly used in bedroom, the GermGuardian AC4200W needs to run even when the user is in room and sleeping. That’s why it is necessary to make an air purifier with completely 100% ozone-free. Without the addition of UV-C light filter or ionizer, the GermGuardian AC4200W follows the same method as the top devices in this price range, like Honeywell HPA060, Levoit Vista 200 or Airthereal ADH80.

Okay, I know you need a test to settle down the winner in the budget segment. The performance test was run in a room of 100 square feet, and I let all air purifiers run in 1 hour. Our today unit, the GermGuardian AC4200W had a quite impressive performance, with efficiency of 99.7% for trapping any particles down to 0.3 microns. If you want to improve the performance, I suggest you look for the GermGuardian AC4300BPTCA or GermGuardian AC5000.

We use the new all-in-one air filter – the FLT4200 filter L for this new air purifier. You only need to replace the air filter after 6-8 months, however, the cost of this filter is a little bit higher than normal, up to $39.

GermGuardian AC4200 Room Coverage

Guardian Technologies takes the safe route to the compact GermGuardian AC4200 model, resulting in a small room coverage and low fan power. The air purifier is verified by AHAM, to run in a small area of 105 square feet. It is just the same as the GermGuardian AC4100 and GermGuardian AC4150.

The ACH of GermGuardian AC4200 is 4X. Even for a compact air purifier, Guardian Technologies enhances the fan to let it exchange air in your room 4 times per hour.

The CADR of GermGuardian AC4200 is 76 Dust/ 68 Smoke/ 77 pollen (cfm).

GermGuardian AC4200 Sound

GermGuardian AC4200 could be the first air purifier from the family of Guardian Technologies to be marketed with “ultra-quiet operation”. Even though the company doesn’t officially state the noise level of the device, it is truly a progress in making air purifiers for bedroom from the American brand.

The average noise level of this GermGuardian AC4200 is only 35 decibels (db), which is better than any other old members for quiet operation. In fact, this noise level is lower than the library, and you won’t notice any sound while operating.

GermGuardian AC4200 Power Consumption

To be one of the best air purifiers, one device must strictly pass our Breathe Quality test after a long time use. Also, one of the most asked questions in Breathe Quality is: “Do air purifiers use a lot of energy?”. We can all agree that power consumption is one important criteria to review if this air purifier is worth your money or not.

Power consumption looks good on this air purifier, due to the removal of UV-C bulb. GermGuardian AC4200 uses only 26 watts on average, which earned it an Energy Star rating for meeting strict energy efficiency guidelines set by the EPA.

For using a GermGuardian AC4200 8 hours per day, it would cost you just $9 per year.

GermGuardian AC4200 Additional Features

Additional features generally aren’t expected from low-end products of Guardian Technologies, however, this time we get a simple but necessary Timer, to schedule the time off for 2, 4 and 8 hours.

This air purifier has 4 fan speeds, with an addition of Turbo mode, to let the device clean with the highest fan power. If you use it when sleeping, you need to enter the Sleep Mode, or the lowest setting, to turn off all the indicator light from this GermGuardian AC4200.

Finally, we have a LED indicator for filter replacement. It is nice to have something remind you when to change the filter.

Our verdict

Another budget air purifier in the lineup of Guardian Technologies. Well, it is a basic air purifier that offers not better than a Levoit Vista 200 or Airthereal ADH80, if not want to say it has less features. However, the device is truly suitable for any fans of this brand, because this is the only compact air purifier that you need for your bedroom.
