GermGuardian AC9200WCA Air Purifier: Trusted Review & Specs

With its solid performance, strong build, and great fan power, the GermGuardian AC9200WCA is a great way to get a flagship air purifier that looks and feels expensive but does not cost the earth. Since the new direction of the GermGuardian AC5900W, Guardian Technologies has truly committed to making big-size air purifiers. And today, we will find out the truth in our GermGuardian AC9200WCA Review.

Guardian Technologies‘ first entry into the mid-range market packs an eye-catching design, an impressive air cleaning system, and a competitive price range. What’s not to love? Together with us, let’s see what this American tech giant wants to deliver in our GermGuardian AC9200WCA Review.

Other GermGuardian’s Air Purifier Reviews:

GermGuardian AC9200WCA Price

We stated a lot in the previous GermGuardian reviews about how this brand is going to push into the mid-range market, starting with the bigger-than-average GermGuardian AC5900WCA and then the smaller GermGuardian AC5600WDLX. In fact, the company has released three consecutive air purifiers with a volley of changes to the design. Most American air purifier lovers could expect more, but first let’s check the price.

As the name implies, the GermGuardian AC9200WCA is a different product line from the previous GermGuardian’s air purifiers, starting with the number “9.” For that upgrade, the GermGuardian AC9200WCA comes with a price of $399, which is double the price of these “5” flagships, like the GermGuardian AC5900WCA and the GermGuardian CDAP5500BCA.

This price translates into a larger body and larger fan size. However, with a $399 price tag, the company puts its GermGuardian AC9200WCA into a really difficult battle with other candidates like Rabbit Air BioGS 2.0, Alen BreatheSmart FLEX and of course, Honeywell AirGenius 6. Competing with these domestic air purifiers, is there any chance for this new GermGuardian AC9200WCA to win a niche? We’ll find out right now, but first, take a look at a $85 discount, which brings the price of this American flagship, the GermGuardian AC9200WCA, down to $314 (includes an $8.6 coupon, pricing may vary depending on when you click on the deal below).

GermGuardian AC9200WCA Design and Size

The GermGuardian AC9200WCA is a sandwich of a large fan with a polished plastic body filling. It’s wider and bigger than the GermGuardian AC5900WCA and even the Honeywell HPA300, but feels much more aesthetic thanks to a stylish handle on top and the curving angles, which are only available in this air purifier.

The front panel stays the same as classic GermGuardian air purifiers, mostly for the beauty, not for the performance. To rate both the beauty and the efficiency of this panel, I prefer the Rabbit Air BioGS 2.0 more, mostly because of its smarter design. However, Guardian Technologies solved that by making a bigger fan and therefore maintaining the performance rating.

Since the AC5900W, Guardian Technologies has improved the bottom-to-top airflow design language to fit the broad size of the GermGuardian AC9200WCA. This concept is also the most popular among the mid-range air purifiers, like the Rabbit Air BioGS 2.0 or the Alen BreatheSmart FLEX, so you can believe in the new GermGuardian AC9200WCA.

Again, on top of this GermGuardian AC9200WCA, we can see a simple control panel with 4 buttons, as you can see below.

germguardian ac9200wca review


There is only White color option for this GermGuardian AC9200WCA, the same as the previous GermGuardian AC5900WCA. I don’t know if Guardian Technologies has plans to add a popular Black version or not, but it seems that the company is in love with the white tone at the moment. New air purifiers like the GermGuardian AC5109W and GermGuardian AC9600W also come in only white.

The GermGuardian AC9200WCA is also the biggest air purifier of this brand at the moment, with 27 inches in height and 17 inches in width. This air purifier weighs 21 lbs, which is a little bit more than the Rabbit Air BioGS 2.0. However, you can still move this air purifier easily from anywhere in your home.

GermGuardian AC9200WCA Filters

When it comes to the raw performance of an air purifier, we decide based on how many filters it has and the types of air filters it uses. The GermGuardian AC9200WCA maintains the same signature four-stage air cleaning system, but with improved efficiency. 

  1. Pre-filter – A normal pre-filter screen that can capture large dust particles and pet hair, mostly to help extend the True HEPA filter life.
  2. True HEPA filter – GermGuardian AC9200WCA uses True HEPA filter to filter up to 99.97% of as small as 0.3 microns of particles like household dust, pet dander, mold spores, and plant pollen.
  3. Activated Carbon Filter – The Activated granular carbon filter reduces odors from pets, smoking, and cooking, along with harmful VOCs emitted from a variety of household products and chemicals.
  4. UV-C Light – The latest GermGuardian UV-C light bulb kills germs without the use of chemicals and produces no ozone or chemical sprays. It can also kill airborne bacteria, viruses, and mold spores.

It’s truly quantity over quality. In its body, the GermGuardian AC9200WCA stacks 2X the true HEPA filters and activated carbon filters to improve filtration efficiency against all types of allergens and gaseous chemicals. Clearly, the implementation is more advanced than the previous-generation technology we saw on the GermGuardian AC5900WCA or GermGuardian CDAP5500BCA. And with that installation, the GermGuardian AC9200WCA’s performance rating is truly stunning.

In comparison to others in the same price range, the GermGuardian AC9200WCA needs this double filtration because it doesn’t have an ionizer like the Rabbit Air BioGS 2.0 or Plasmacluster Ion in the Sharp FP-A80UW. Without these trapping technologies, an extra physical filter is necessary.

To test the performance of this GermGuardian AC9200WCA, I put it in a room of 200 square feet and let it run for 1 hour. I also used the GermGuardian AC9400W, Levoit LV-H134, Winix HR1000, and Alen BreatheSmart 45i to compare the results of this air purifier. For the result, the Winix HR1000 scored an efficiency of 99.97% for trapping any particles as small as 0.3 microns. The Levoit LV-H134 was the runner-up with 99.95%, while the GermGuardian AC9200WCA was only at 99.9%. The lowest score was the Alen BreatheSmart 45i, with an efficiency of only 99%.

germguardian ac9200wca review

In GermGuardian AC9200WCA, you still have the signature UV-C light filter. Guardian Technologies knows exactly what to put in its air purifiers to compete with others. An UV-C light bulb, while consuming more energy, doesn’t produce any ozone and, as a result, can’t irritate any breathing issues. The fact that only this American brand still works in combination with both an air purifier and an air sanitizer makes this GermGuardian AC9200WCA a little bit more special.

germguardian ac9200wca review


GermGuardian AC9200WCA uses the latest Filter H from this brand, with a higher cost of $79, and needs to be replaced after 6 to 8 months of use. You should notice that the cost is quite similar to the BioGS HEPA filter of the Rabbit Air BioGS 2.0, but with a lot less lifetime. Due to the shorter life, the average filter replacement cost of this GermGuardian AC9200WCA is still higher than normal.

However, we have a great deal to discount the filter cost to only $45, and you should grab it as soon as possible.

GermGuardian AC9200WCA Room Coverage

Based on my previous experience with the GermGuardian AC5900WCA, I am sure that the room coverage test of this GermGuardian AC9200WCA will not exceed its predecessor. And as a result, we have a closed area of 335 square feet. In this price range, the specified room coverage is small if compared with the Rabbit Air BioGS 2.0 (625 square feet) or Alen BreatheSmart FLEX (700 square feet). But don’t just give up on this air purifier; let’s scroll a little below.

The ACH of GermGuardian AC9200WCA is 5X. The high air changes per hour rating allows this air purifier to deliver more airflow to clean your room. In short, your room of 335 square feet will be cleaned once every 12 minutes.

The CADR of GermGuardian AC9200WCA is 216 Dust/ 216 Smoke/ 265 pollen (cfm). This CADR rating is quite the same as the AC5900WCA and shows exactly how fast the GermGuardian AC9200WCA can clean your room. You don’t need to be good at math to know that the GermGuardian AC9200WCA can clean your room faster than a Rabbit Air BioGS 2.0 (with a CADR of 170 cfm). Cleaning your room faster means you can turn off the air purifier sooner, saving some precious energy in your home.

GermGuardian AC9200WCA Sound

On paper, this company never specifies the noise level or adds the title of “quiet air cleaner” for marketing. With no confirmation of these things, it’s easy to assume that this GermGuardian AC9200WCA is not a silent air purifier. That makes sense because the sound is unmistakable with a higher fan power.

Even at the lowest setting, the noise level of the GermGuardian AC9200WCA can reach 40 decibels, which is higher than most of the normal air purifiers on the market. For example, the AeraMax 300 is only 35 decibels, the Sharp FP-A80UW is 23 decibels, and the Rabbit Air BioGS 2.0 is only 22.8 decibels.

And when you switch to the highest setting, the noise level of the GermGuardian AC9200WCA can reach as high as 60 decibels (dB). This is the noise level of a public restaurant or an air conditioning unit at 100 feet. I bet most of our beloved readers won’t find this noise level acceptable.

With only 3 fan speeds, the GermGuardian AC9200WCA produces lots of noise on the highest setting. If you need this air purifier when you sleep or when you need to work in silence, you should only run it on the lowest setting. Or else, I believe the Rabbit Air BioGS 2.0 is a much better choice.

GermGuardian AC9200WCA Power Consumption

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

The addition of an UV-C light increases power consumption, but the GermGuardian AC9200WCA is an Energy Star certified air purifier. This time, the American manufacturer has decreased the power consumption of this air purifier to just 52 watts, which is better than the 83 watts of the GermGuardian AC5900WCA. If you manage to run the air purifier mostly on the low setting, you don’t need to pay much for your energy bill.

It would cost up to $19 per year to use a GermGuardian AC9200WCA for 8 hours per day. As you can see, the annual cost is small, and you shouldn’t think about it all day.

GermGuardian AC9200WCA Additional Features

GermGuardian is well-known for including Smart features in even the $200 low-end air purifiers, but this flagship of the American brand has none. We can accept that the Wi-Fi connectivity function is still new in air purifiers, and apart from the Blueair Classic 205, there is no air purifier in this price range offering Smart Connection. But removing the Smart Sensor is kind of strange, because a mid-range air purifier really needs this air sensor for a better user experience.

Okay, so back to a classic GermGuardian air purifier, with only one timer to save you. Last but not least, you still have the LED indicator for filter replacement. This function is so common that I don’t want to repeat it here.

GermGuardian AC9200WCA Customer Service

There is not much to say about the brilliant support from Guardian Technologies’ customer service. Anyone can get active support from the American brand. The company also makes the instruction manuals available online to help you answer common questions on your own. But if you can’t find a solution, just contact customer service via phone at 866-603-5900 or via email at Just like any other brand, the office will be open from Monday to Friday.

Guardian Technologies occasionally offers free shipping as well as a significant discount on all products (typically 10% to 20%). Whenever you find the air purifiers are not as great as you had thought, you can return them within 30 days of your original receipt of the order. And don’t worry about the warranty policy of Guardian Technologies, as it warrants its products to be free of defects in materials or workmanship. You can register for a warranty for up to five years.

For the GermGuardian AC9200WCA, you will have a 3-year warranty.

Our verdict

Guardian Technologies must commit to a higher quality air filter in order to raise the bar to $399, which is exactly what the company does for the latest GermGuardian AC9200WCA. But, once again, this American brand overlooks what it could offer its customers – the Smart features. If you love the Smart Sensor, you should choose the GermGuardian AC9400W instead.
