GermGuardian AC5600WDLX Air Purifier: Trusted Review & Specs

The GermGuardian AC5600WDLX is brilliantly cheap, but not brilliant value. In one sense, the new GermGuardian air purifier is always one of the most anticipated air purifiers this year. But to be our top ultra-affordable air purifier kick, it’s another story. Let’s find out in our today GermGuardian AC5600WDLX Review.

GermGuardian AC5600WDLX ranks C+ in our air purifier ranking list

  • Solid build quality
  • Decent performance
  • Energy Star rating
  • 3-year warranty

  • Lacks of additional features
  • Quite noisy
  • High filter replacement cost

Guardian Technologies returns to the ultra-affordable air purifier market after an extended absence with the latest flagships. However, unlike the hype of the GermGuardian AC4200, the performance of GermGuardian AC5600WDLX makes a strong case for spending a bit more. Why? Let’s find out in our GermGuardian AC5600WDLX Review.

Other GermGuardian’s Air Purifier Reviews:

GermGuardian AC5600WDLX Price

The GermGuardian AC5600WDLX tends to be a true budget air purifier to fit the gap from the low-end price point to the GermGuardian AC5900WCA. Certainly it isn’t as cheap as the popular tower air purifier series from this family, but if all you care about are the basics, this is a good-to-go device.

Guardian Technologies is frequently one of the best manufacturers offering air purifiers tested and certified by both the California Air Resources Board (CARB) and the Energy Star. For a device with both certifications, the performance of this GermGuardian AC5600WDLX must be more stable than other unknown devices, mostly from Chinese manufacturers in the market.

At $149, the GermGuardian AC5900WDLX continues the price-conscious philosophy of the range. It shouldn’t surprise you to guess the official price tag, but should you choose it over the common GermGuardian AC5350B, or more preferably, GermGuardian CDAP5500BCA?

Especially as there are now other similarly priced players on the market, such as the Levoit LV-PUR131 or Medify MA-18. Both air purifiers are from the well-known companies with U.S origin, and they have even higher performance than our today air purifier for the same price. Luckily, you can get the GermGuardian AC5600WDLX from our deal, for a much lower price, up to only $119.

GermGuardian AC5600WDLX Design and Size

Aesthetically speaking, the GermGuardian AC5600WDXL is almost remarkable in its unremarkableness. It’s a deeply generic design from classic air purifiers, but it doesn’t hark back to previous GermGuardian air purifiers. It is now a console air purifier, with a new style that you can’t say it is just a copy of GermGuardian AC5900WCA or GermGuardian AC9200WCA.

There’s little if any attempt at flair, as the dimension of 21.5 inches (height) x 15 inches (width) of the GermGuardian AC5600WDLX is quite similar to the more expensive AC5900WCA. Using the same material to make the body, this air purifier is quite solid built, and any attempt to replicate the look of more expensive devices would be okay.

The GermGuardian AC5600WDLX sports a familiar bottom-to-top air flow system concept, with the air intake under the front plate. The top air grills have large space to deliver more air, and there is a hidden handle at the center to help you lift it.

On top of this air purifier, we can see a simple control panel with 4 functional buttons.

GermGuardian AC5600WDLX weighs just 8 lbs, which is a lot lighter than the other console members of Guardian Technologies.

GermGuardian AC5600WDLX Filters

GermGuardian AC5600WDLX, following the new product line of Guardian Technologies, removes the signature UV-C light filter completely. It uses a simple 3-stage air cleaning system, just like the flagship GermGuardian AC9400W.

  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 AC5600WDLX 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.
  3. Ionizer – Instead of using the UV-C light filter, this GermGuardian AC5600WDLX will use an ozone-safe ionizer function to enhance the ability to remove particles and keep the air fresh. Can be switched on/off.

Again, I used this GermGuardian AC5600WDLX in a space of 100 square feet, to test it performance against many other air purifiers at the same price range like Airthereal APH260 and InvisiClean Sensa. I also brought a GermGuardian AC5000 into the test to help you know why the GermGuardian AC5600WDLX is more expensive. As you can see from the chart below, the GermGuardian AC5600WDLX has a high efficiency, to trap 99.92% of any particles down to 0.3 microns in just 1 hour. However, the result for a much larger room will be a disadvantage for such low fan power like the GermGuardian AC5600WDLX.

For the new air purifier, you need a new air filter. The GermGuardian FLT5600 filter N is recommended to use only for the GermGuardian AC5600WDLX. It is cheaper than the filter J of GermGuardian AC5900WCA, but $45 is still high for a low-end product. Moreover, you need to replace it after 6-8 months, meaning the annual filter cost is even higher.

GermGuardian AC5600WDLX Room Coverage

GermGuardian AC5600WDLX can be a console air purifier with the same size as the GermGuardian AC5900WCA, but its fan power is much lower. That’s why the AHAM verified room coverage of this GermGuardian AC5600WDLX is just only 151 square feet – the size of small and medium rooms.

The ACH of GermGuardian AC5600WDLX is 4X. At max speed, this air purifier can clean your room every 15 minutes.

The CADR of GermGuardian AC5600WDLX is 105 Dust/ 97 Smoke/ 101 Pollen (cfm). Such CADR rating is even lower than the sub-$100 tower devices like GermGuardian AC4825 or GermGuardian AC4900CA.

GermGuardian AC5600WDLX Sound

Again, Guardian Technologies told us that we will have an “ultra-quiet operation” air purifier. The fact is, they don’t officially state the noise level of the device, and just like many other air purifiers in the family, the quiet operation isn’t truly the selling point of the GermGuardian AC5600WDLX.

I’ve measured the average noise level of this GermGuardian AC5600WDLX to be from 50 to 60 decibels (db), which is really high for an air purifier with such low fan power. Make sure to keep it away from you when you need silence.

GermGuardian AC5600WDLX 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.

As an Energy Star air purifier, the GermGuardian AC5600WDLX just has a power consumption of 44 watts, which is a lot better than the GermGuardian AC5900WCA.

For using a GermGuardian AC5600WDLX 8 hours per day, it would cost you just $16 per year.

GermGuardian AC5600WDLX Additional Features

GermGuardian AC5600WDLX is just the budget console air purifier from Guardian Technologies, so it doesn’t come up with many additional features.

Just like the GermGuardian AC5900WCA, we can only expect a basic Timer for this air purifier, which is customizable up to 8 hours. There is also a LED indicator for filter replacement, so you don’t need the date manually.

Our verdict

Another budget console air purifier from Guardian Technologies, but considering many good air purifiers out there, I don’t have much faith in the new GermGuardian AC5600WDLX. Perhaps, with the upcoming reduce in price, the device could compete well with… its own brothers in sub-$100 range.
