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 pick for an ultra-affordable air purifier, it’s another story. Let’s find out in today’s GermGuardian AC5600WDLX Review.

Update: If you’re looking for higher efficiency, you should look for the GermGuardian AC5900WCA or GermGuardian AC9200WCA.

GermGuardian AC5600WDLX ranks C+ in our air purifier ranking list. We give the biggest and most thorough database of air purifier reviews in the world.

  • 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 its latest flagships. However, unlike the hype of the GermGuardian AC4200, the performance of the GermGuardian AC5600WDLX makes a strong case for spending a bit more. Why? Let’s find out in our GermGuardian AC5600WDLX Review.

GermGuardian AC5600WDLX Price

The GermGuardian AC5600WDLX is a true budget air purifier that bridges the gap between the low-end price point and 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 regarded as one of the best manufacturers of air purifiers that have been 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 that of 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, the GermGuardian CDAP5500BCA?

There are now other similarly priced players on the market, such as the Levoit LV-PUR131, Levoit Core 300S, or TCL Breeva A3. Both air purifiers are from well-known companies, and they have even higher performance than our current 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 has a very generic design from classic air purifiers, but it has nothing in common with previous GermGuardian air purifiers.It is now a console air purifier, with a new style that you can’t say is just a copy of the GermGuardian AC5900WCA or GermGuardian AC9200WCA.

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

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

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

The GermGuardian AC5600WDLX weighs just 8 lbs, which is a lot less than the other consoles from 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 an Activated Carbon filter, this layer of air filter can remove the majority of large pollutants and reduce odors caused by 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 its performance against many other air purifiers in the same price range, like the Airthereal APH260 and the InvisiClean Sensa. I also brought a GermGuardian AC5000 into the test to help you understand why the GermGuardian AC5600WDLX is more expensive. As you can see from the chart below, the GermGuardian AC5600WDLX has a high efficiency, able to trap 99.92% of any particles down to 0.3 microns in just 1 hour. However, the result of a much larger room will be a disadvantage for a fan with such low power like the GermGuardian AC5600WDLX.

For the new air purifier, you need a new air filter. The GermGuardian FLT5600 filter N is recommended for use only with the GermGuardian AC5600WDLX. It is cheaper than the filter J of the 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

The 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 151 square feet, the size of small and medium rooms.

The ACH of GermGuardian AC5600WDLX is 5X. At max speed, this air purifier can clean the suggested room size every 12 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 the GermGuardian AC4825 or GermGuardian AC4900CA.

GermGuardian AC5600WDLX Sound

Again, Guardian Technologies told us that we would have an “ultra-quiet operation” air purifier. The fact is, the company doesn’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, a device must strictly pass our Breathe Quality test after long-term use. Also, one of the most frequently asked questions in Breathe Quality is: “Do air purifiers use a lot of energy?” We can all agree that power consumption is one important criterion to review to determine if this air purifier is worth your money or not.

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

It would cost you only $16 per year to use a GermGuardian AC5600WDLX for 8 hours per day.

GermGuardian AC5600WDLX Additional Features

GermGuardian AC5600WDLX is just the budget console air purifier from Guardian Technologies, so it doesn’t come 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 to set the date manually.

Our verdict

Another budget console air purifier from Guardian Technologies, but with so many good air purifiers on the market, I’m not sure I trust the new GermGuardian AC5600WDLX. Perhaps, with the upcoming reduction in price, the device could compete well with… its own brothers in the sub-$100 range.
