GermGuardian AC5250PT Air Purifier: Trusted Review & Specs

Sometimes air purifiers can seem a bit boring. Every year, the same companies make the same air purifier but with a few tweaks, an upgrade in HEPA filter and a new name.

Updated: The flagships of this brand are the GermGuardian AC9400W and GermGuardian AC9600W. But if you are looking for a Smart air purifier, you should search for either the GermGuardian CDAP5500BCA or GermGuardian CDAP4500BCA.

Let’s read our GermGuardian AC5250PT Review.

GermGuardian AC5250PT Price

At first glance, you might think the GermGuardian AC5250PT and GermGuardian AC5000 are the same air purifier. Actually, these two GermGuardian air purifiers have too much things in common, and the price tags are just $10 in difference.

GermGuardian AC5250PT stays at the same price with its modern brother – the GermGuardian AC5300B, which is available for $129. At the time of writing there’s a deal in Guardian Technologies, but you can find an even better deal just following our button below, so the air purifier is only $119.

This air purifier is capable of competing with the Honeywell HPA030B and TCL Breeva A2, the greatest rival of Guardian Technologies. However, with an unique combination of Pet Pure HEPA filter and UV-C light filter, the GermGuardian AC5250PT is strong enough to hold its position.

GermGuardian AC5250PT Design and Size

As the improvement of the AC5000, it is really hard to spot the differences between the 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, the 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 airflow 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 the 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 the air filter types are used. GermGuardian AC5250PT once again uses the same 3-in-1 air cleaning system as the GermGuardian AC5000 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, the 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. The company calls its 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.

germguardian ac5000e review


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

To test the performance, I chose the GermGuardian AC5350B and Honeywell HFD280B 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 had the very good efficiency of capturing 99.9% down to 0.3 microns particles. The Honeywell HFD280B, however, had a higher efficiency of 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 AC5000. The room coverage is 180 square feet. Also other fan power indicator specs of the GermGuardian AC5250PT is exactly the same with the GermGuardian 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 AC5250PT is 126 Dust/ 116 Smoke/ 128 pollen (cfm). This CADR rating of GermGuardian AC5250PT even surpass the CDAP5500BCA a little bit.

GermGuardian AC5250PT Sound

One major difference from GermGuardian AC5250PT with others in the same price range like the AC5000 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.

Even at the lowest setting, the noise level of the GermGuardian AC5250PT is 40 decibels, which is higher than most of the normal air purifiers in the market. For example, the AeraMax 300 is only 35 decibels, the SilverOnyx can be as low as 25 decibels, or the Winix 5300-2 with only 28 decibels.

And when you switch to the highest setting, the noise level of the GermGuardian AC5250PT can reach as high as 60 decibels (dB). This is such a noise level of the public restaurant, or an air conditioning unit at 100 feet. And this noise level is the culprit of many headache cases for users.

One again, we hold our own opinion that you should keep the fan speed at low setting while using the 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 8 watts UV-C bulb, the GermGuardian AC5250PT consumes much more energy than the modern GermGuardian AC5300B or GermGuardian AC5350B. We have recorded a high power consumption of 70 watts, which is really a problem because it is higher than most of the normal air purifiers for the price.

For using a GermGuardian AC5250PT 8 hours per day, it would cost you up to $25 per year. It is not much higher than other air purifiers from this brand, so you won’t hate the GermGuardian AC5250PT too much if you had used many GermGuardian devices in the past.

GermGuardian AC5250PT Additional Features

For the same price with the AC5300B, the 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 the AC5000E or AC5300B as well. We guess that how Guardian Technologies tries to tell the different between its models with same appearance.

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