GermGuardian AC5900W Price
To commit in making bigger air purifiers, the Guardian Technologies company needs to enhance both the fan power and the iconic True HEPA filter. With lots of investment, the starting price of GermGuardian AC5900W is a little bit above the average.
Though the air purifier is still under low-range segment, with the price tag of $199, GermGuardian AC5900W reflects the clear direction of this brand to aim at mid-range market. This direction is mostly visualized in the new AC9400W in 2019, which we will make a review for it as soon as possible.
With that price, the GermGuardian AC5900W is go side-by-side with the CDAP5500BCA to be the current $199 air purifiers of this company. One short reminder, the CDAP5500BCA is a smart air purifier with Wifi connectivity, but holding a much weaker fan power than GermGuardian AC5900W. Should you need the better performance, you can’t go wrong with this GermGuardian AC5900W.

GermGuardian AC5900W Design and Size
The company has now reworked the original design and returned with this GermGuardian AC5900W, a more refined, logical and a favorable concept. Now, there is no any 28-inch tower with a really confused design language. Instead, with the use of a 21-inch height and 16-inch width, this gives the GermGuardian AC5900W a solid profile, making us feel the greater fan power than the predecessors.
As far as affordability is concerned, the GermGuardian AC5900W has a few tricks to save costs whilst still delivering as a solid air purifier package. The majority of the air purifier is still plastic, and there is no signature circular light on the front panel anymore. However, this air purifier is assembled in such a way that the company has ensured the GermGuardian AC5900W still look plenty stylish.
GermGuardian AC5900W even pushes far away from the original design, to be the first of its kind to have a bottom-to-top air flow system. To do that, GermGuardian AC5900W uses a huge air intake grill from the front and a smaller air outlet grill on top. This design is borrowed from almost all of $200 air purifiers, such as Honeywell HPA300, Coway AP-1512HH, and Levoit LV-PUR131. Even at $369, a Design Award Winner – Rabbit Air BioGS 2.0 – make use of the same air flow concept, too. That is indeed a great compliment for GermGuardian AC5900W.
On top of this GermGuardian AC5900W, beside the air grill, we will have a common control panel with 5 functionality buttons.
We will have only one color option, as the GermGuardian AC5900W just only come with White version. Honestly, I like the Black version of GermGuardian’s air purifier more, as the Black Onyx color is much more premium, in my opinion.

GermGuardian AC5900W Filters
The GermGuardian AC5900W comes with a 3-in-1 air cleaning system which features the power of a product line, with the combination of 3 most popular air filter types, to guarantee an absolute purification.
- Pre-filter – A normal pre-filter with Activated Carbon Filter to remove the large particles of pollutants and reduce odors created from smoke, cooking, and pets.
- True HEPA filter – GermGuardian AC5900W uses a True HEPA Filter to capture 99.97% of microscopic allergens, dust and mold spores as small as 0.3 microns in size.
- UV-C Light – This air purifier is also using an UV bulb to kill airborne bacteria, viruses and mold spores.
To improve the performance rating, GermGuardian AC5900W runs a new True HEPA filter which is one and a half times as big as an average GermGuardian’s air filter. Increasing the surface is the best way to utilize the fan power and increase the trapping efficiency of this air purifier. However, the Filter J of GermGuardian AC5900W is not upgrading with Pet Pure Treatment, which is widely used in the latest of this brand, like CDAP5500BCA or GermGuardian AC5350B.
I set up a performance test for the GermGuardian AC5900W along with the Levoit LV-PUR131. It is quite insufficient for the GermGuardian CDAP5500BCA to stay in the same test conditions, in a room of 150 sq ft and duration of 1 hour, but I was willing to make a deep comparison to see the performance of GermGuardian AC5900W. The result, both the GermGuardian AC5900W and Levoit LV-PUR131 can trap 99.9% of down to 0.3 microns particles. The CDAP5500BCA is weaker in a large room, and has efficiency of only 99.5%.
Moreover, a signature GermGuardian’s air purifier needs the support of an UV-C light bulb. This 5W UV bulb is able to destroy germs, airborne bacteria, viruses and mold spores. This combination is truly what makes Guardian Technologies stand out of the crowd at the moment.
As usual, this True HEPA filter needs 6-8 months to be replaced. And with that short time, a $69 air filter will hold you back from buying a new one. It is disappointed that a low-range air purifier like GermGuardian AC5900W has such high filter replacement cost like that.

GermGuardian AC5900W Room Coverage
Trading off the smart features for the power, GermGuardian AC5900W is exactly what customers demand from this brand, the larger room coverage. That being said, this GermGuardian AC5900W can handle a room of up to 338 sq ft. This room coverage is quite similar to others in same price range, like Coway AP-1512HH and Winix WAC9500.
The ACH of GermGuardian AC5900W remains 4X. With that high air changes per hour rating, this air purifier can clean your room every 15 minutes.
The CADR of GermGuardian AC5900W is 220 Dust/ 218 Smoke/ 215 pollen (cfm). This CADR rating is just better than the slow Levoit LV-PUR131, but no way near the fan power of Honeywell HPA300. We must again remind you that CADR rating doesn’t tell you the performance of your air purifier, only how fast this device can clean your room. In a 338-sq-ft room, GermGuardian AC5900W can pass any difficult tests with no struggle.

GermGuardian AC5900W Sound
With only 3 fan speeds, this GermGuardian AC5900W is still as noisy as an average 5 to 6 fan-speed-air purifier. It’s not hard to tell the culprit, a bigger size device like GermGuardian AC5900W needs a bigger fan, which produces a higher noise level.
If you don’t want this air purifier to disturb you, I suggest that you keep running this GermGuardian AC5900W at low setting whenever possible.

GermGuardian AC5900W Power Consumption
One of our most FAQs is “Do air purifier 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.
With the use of a new built-in 5W UV-C bulb and much more fan power, GermGuardian AC5900W runs at 145W, and can kill your energy bill easily. To save your precious money when use an air purifier for a long time, we suggest you search for Coway AP-1512HH, Levoit LV-PUR131, and Blueair Sense +.
For using a GermGuardian AC5900W 8 hours per day, it would cost you up to $55 per year, which is nearly a quarter of the cost of this air purifier.
GermGuardian AC5900W Additional Features
Guardian Technologies, like so many other budget air purifier brands, has replaced the quality of its air filter for lots of marketing aspects like Smart features, modern appearance and of course, the add-on of UV-C light bulb. On the other hand, within this GermGuardian AC5900W, the company decide to give out the great performance and fan power for the price. Honestly, I believe more in the performance of one air purifier, and this new direction of Guardian Technologies truly deserves some praises.
That’s why, we shouldn’t expect anything from this air purifier. The only feature that is available in GermGuardian AC5900W is only one Timer, to auto turn off the device and save more energy.
Luckily, we still have a handy LED indicator for filter replacement. With this function, you no longer need to remember the replacement date anymore.
GermGuardian AC5900W Customer Service
There is not much to say for the brilliant support from GermGuardian’s Customer Service. You can reach them easily via phone or email at anytime.
And the warranty policy of Guardian Technologies is also among the longest to guarantee against all defects, with up to 5 years warranty.
For under $200, GermGuardian AC5900W is definitely a good deal when it has a combination of both True HEPA filter and UV-C light filter as other $300 air purifiers. However, if you prefer a better performance, you should go for Honeywell HPA300 or Coway AP-1512HH, with much better fan power and slightly higher efficiency. Or if you need more smart features for your device, a CDAP5500BCA or especially, Blueair Sense + would fit you better.
- Cleaning Power
- Power Consumption
It’s an easy buy for anyone who places performance, fan power and quality ahead of the aesthetics of conventional flagship air purifiers. However, the GermGuardian AC5900W is still not the best performance air purifier for the price.
