GermGuardian AC5000E Price

As the first one in GermGuardian’s 28-inch family, clearly GermGuardian AC5000E will hold the lowest cost. Within a same performance, you can purchase this air purifier as an alternative to a $10 more GermGuardian AC5300B, for the price tag of $119. The price is exactly the same with GermGuardian AC4300BPTCA – a smaller 22-inch device.

There is a feeling of familiarity about the GermGuardian AC5000E. Not to mention a whole bunch of air purifiers that share the same design with this air purifier, this style makes me feel like the classic PureGuardian, which is also a brand of Guardian Technologies.

Another nice addition, especially on something many would consider a ‘budget’ device, this air purifier is now using the latest air filter from the manufacturer, which increases its value more. For $10 more than the Levoit LV-H132, you are able to deal with bacteria and viruses with the UV-C light in this air purifier.

GermGuardian AC5000E Design and Size

As the first design for GermGuardian Tower air purifiers family, GermGuardian AC5000E has the same concept with the previous PureGuardian of Guardian Technologies company. That being said, you will have a 28-inch tower with a huge air output grill from the front and an also big intake grill from the back. With the classic air flow from back to front (which hasn’t changed since the first air purifier of this brand), this design can easily maximize the power of AC5000E’s fan.

There’s not much at the top of this air purifier, with only one UV-light button, one on/off button, one fan speed switch and a LED filter replacement indicator.

GermGuardian AC5000E weighs only 10.5 lbs – the same weight with other 28-inch tower air purifier in GermGuardian family.

GermGuardian AC5000E Filters

To decide the power of an air purifier, basically we will look at how many filters it has and what types of air filters are used. With a 3-in-1 air cleaning system, GermGuardian AC5000E is able to defend against any types of allergens and bacteria.

  1. Pre-filter – A common GermGuardian pre-filter with Activated Carbon Filter to remove the large particles of pollutants and reduce odors created from smoke, cooking, and pets.
  2. True HEPA filter – GermGuardian AC5000E uses a True HEPA Filter to capture 99.97% of microscopic allergens, dust and mold spores down to 0.3 microns in size.
  3. UV-C Light – This air purifier is also using an UV bulb to kill airborne bacteria, viruses and mold spores.

Installing a same set of filter as GermGuardian AC5300B, the fact that this air purifier is $10 cheaper will make it easy to sell to practical people. After testing all of the GermGuardian air purifiers, we can assure that AC5000E’s performance rating is not inferior to its brothers. With an addition of an UV-C light bulb, the 3-in-1 air cleaning system from GermGuardian is one of the best technologies to deal with the tiny particles of contaminants.

That is, like the AC5300B, GermGuardian AC5000E has the same efficiency of 99.9% for trapping any particles as small as 0.3 microns. The test conditions are 100 sq ft room and duration of 1 hour. This efficiency is even higher than the Honeywell HFD280B (with 90%), which is $10 more when buying.

Remember that you can use the same filter in an AC5000E like AC5250PT, AC5300B or even CDAP5500BCA. That means you don’t need to pay an extra of $70 to use the best air filter of Guardian Technologies. It should also be noted that today Guardian Technologies has two layers of True HEPA filter for different purpose. The last but not least, you need to change the air filter every 6-8 months base on 24/7 use.

GermGuardian AC5000E Room Coverage

GermGuardian AC5000E stays the low-medium room coverage of 180 sq ft.

The ACH of GermGuardian AC5000E is 4X. The rating of air changes per hour is similar in all tower air purifiers of this brand.

The CADR of GermGuardian AC5000E is 123 Dust/ 116 Smoke/ 128 pollen (cfm). This air purifier’s CADR rating is a little bit higher than the $200 CDAP5500BCA of Guardian Technologies. With this CADR rating and high ACH, we can rest assured that GermGuardian AC5000E is effective in cleaning a room area of 180 sq ft.

GermGuardian AC5000E Sound

As the classic version of AC5300B, GermGuardian AC5000E is running with 3 fan speeds. Despite of the advertisement of ultra quiet at lowest setting, we can’t avoid the noticeable sound when using AC5000E at full fan speed.

Just like any other tower devices in GermGuardian’s family, GermGuardian AC5000E is not a perfect option for quiet places, such as your office or bedroom.

GermGuardian AC5000E Power Consumption

A good air purifier must be used for a long time to be efficient, and one of the most asked questions in Breathe Quality is: “Do air purifier 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.

Using the old 8W UV-C bulb, GermGuardian AC5000E consumes as much energy as the CDAP5500BCA. We recorded the power consumption of 135W, which is really high for a low fan speed air purifier like GermGuardian AC5000E.

For using a GermGuardian AC5300B 8 hours per day, it would cost you up to $50 per year. We guess the Energy Star rating doesn’t help much to save your energy bill.

GermGuardian AC5000E Additional Features

As the classic air purifier of this brand, GermGuardian AC5000E has nothing but a LED indicator for filter replacement. But what could you expect from this old device of Guardian Technologies in 2018? Remember that even the modern-design version of AC5000E – the AC5300B also doesn’t have any other additional features.

If you are looking for smart features, you need to aim for the the CDAP5500BCA.

Our verdict

This GermGuardian AC5000E is a decent air purifier in low-range market. With a built-in 3-in-1 air cleaning system, this air purifier can do a lot for a 180 sq ft. But running without any additional features back up, it is still difficult choice to go all-in for this air purifier.

Another budget champ from GermGuardian brand. And the fact that it offers the same power as the AC5300B at less than $10 makes it a purchase I can fully recommend.
