GermGuardian AC5250PT Design and Size

As the improvement of AC5000E, it is really hard to spot the differences between GermGuardian AC5250PT and its brother. It really feels like you are trying to differentiate the iPhone X and iPhone XS. Yes, it is definitely like that.

That being said, GermGuardian AC5250PT’s design is exactly the same with the classic design from any GermGuardian 28-inch tower air purifier. Granted, there are shades of the old PureGuardian air purifiers to curved top and patterns, but the classic GermGuardian air purifiers have a distinctive look that proves surprisingly recognizable. A logo brand of GermGuardian with a blue grooved ring to hold the front output air grill. From the back, you will find a big intake grill. The air flow is directed from back to front like any other GermGuardian air purifiers.

From the top of this GermGuardian AC5250PT, we will have a new digital control panel attaching with 4 function buttons. If you ask us if it is worth $10 more than AC5000E, we believe that the answer is “yes”. You can easily manage your air purifier with or without the light.

One more advantage for this GermGuardian AC5250PT is the weight of 10.5 lbs. This air purifier can fit in any types of room and stand like a tower fan.

GermGuardian AC5250PT 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. GermGuardian AC5250PT once again uses the same 3-in-1 air cleaning system as GermGuardian AC5000E with these unique Guardian Technologies’s filters.

  1. Pre-filter – Combining with 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 AC5250PT uses a True HEPA Filter to capture 99.97% of microscopic allergens, dust and mold spores down to 0.3 microns in size. This filter is also including an antimicrobial treatment on it to help prevent against any odors or bacteria from getting trapped in the filter.
  3. UV-C Light – With an UV-C light bulb, AC5250PT can kill airborne bacteria, viruses and mold spores.

GermGuardian AC5250PT is one of the most popular air purifiers from this brand for an apparent reason. This air purifier is the most affordable air purifier using the latest HEPA technology of Guardian Technologies company. They call their air filter Pet Pure Treatment HEPA filter, adding a layer of antimicrobial treatment within the True HEPA filter. As a result, it will inhibit the growth of mold, mildew and odor-causing bacteria on the surface of the filter.

It is safe to say GermGuardian AC5250PT is having the same power with the latest devices from this brand, like GermGuardian AC5350BCDAP4500BCA or even the current CDAP5500BCA. Using an UV-C light bulb, GermGuardian AC5250PT is able to fit in the line of Best air purifiers for mold and mildew.

To test the performance, I chose the GermGuardian AC5350B and Honeywell HPA030B to compare with our GermGuardian AC5250PT. The following result seems to be repeated again and again in any GermGuardian reviews, as both the GermGuardian AC5250PT and AC5350B have the very good efficiency of capturing 99.9% down to 0.3 microns particles. The Honeywell HPA030B, however, has a higher efficiency of 99.92%.

Finally, you also need to change the air filter every 6-8 months base on 24/7 use. For common use, this True HEPA filter can last up to 12 months.

GermGuardian AC5250PT Room Coverage

GermGuardian AC5250PT can cover as much as its brother – the AC5000E. The room coverage is 180 sq ft. Also other fan power indicator specs of AC5250PT is exactly the same with AC5000E.

The ACH of GermGuardian AC5250PT is 4X. This air changes per hour are similar in all tower air purifiers of this brand, and this rating is suitable for both the CADR and the room coverage.

The CADR of GermGuardian AC5300B is 126 Dust/ 116 Smoke/ 128 pollen (cfm). This air purifier’s CADR rating of GermGuardian AC5250PT even surpass the CDAP5500BCA a little bit.

GermGuardian AC5250PT Sound

One major difference from GermGuardian AC5250PT with other in same price range like AC5000E or AC5300B is the fan speed. The advantage is its high fan power, which is as strong as the latest GermGuardian devices. However, the bad side is its high noise level, especially at the highest setting.

One again, we hold our own opinion that you should keep the fan speed at low setting while using GermGuardian AC5250PT in quiet places like your office or bedroom. If you need a decent air purifier with

GermGuardian AC5250PT 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 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.

Using the old 8W UV-C bulb, GermGuardian AC5250PT consumes much more energy than the modern AC5300B. We have recorded a high power consumption of 140W, which is really a problem if you plan to use this air purifier 24/7.

For using a GermGuardian AC5250PT 8 hours per day, it would cost you up to $50 per year. It is not much higher than other air purifiers from this brand, so you won’t hate GermGuardian AC5250PT too much if you had used many GermGuardian devices in the past.

GermGuardian AC5250PT Additional Features

For the same price with AC5300B, GermGuardian AC5250PT has a better digital control panel with a built-in timer. In the writer’s opinion, it is really hard to understand why Guardian Technologies can’t add the simple Timer function in AC5000E or AC5300B as well. We guess that how they try to tell the different between their models with same appearance.

However, you will not have smart features like Smart Sensor or wifi capability in this AC5250PT. To have these features, you must save up for a CDAP4500BCA or CDAP5500BCA.
