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 the HEPA filter, and a new name. Especially in the case of air purifier like the GermGuardian AC5250PT, which makes you think this is the same air purifier with the GermGuardian AC5000. Of course, we will give you a quick overview of the GermGuardian AC5250PT Review to help you spot any differences between these two.

Update: 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 the GermGuardian CDAP4500BCA.

The U.S firm Guardian Technologies is famed for its low-priced and highly competitive air purifiers, and its UV air purifier technology has traditionally led its budget charge. We got our hands on one GermGuardian AC5250PT to see whether this air purifier is really worth considering as an import alternative to its brother – the GermGuardian AC5000 with new HEPA filter technology. Let’s read our GermGuardian AC5250PT Review.

GermGuardian AC5250PT Price

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

GermGuardian AC5250PT stays at the same price as its modern brother, the GermGuardian AC5300B, which is available for $129; At the time of writing, there’s a deal at Guardian Technologies, but you can find an even better deal by 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 two greatest rivals of Guardian Technologies. However, with a unique combination of a Pet Pure HEPA filter and a UV-C light filter, the GermGuardian AC5250PT is strong enough to hold its position.

GermGuardian AC5250PT Design and Size

With the advancement of the AC5000, it is difficult to distinguish between the GermGuardian AC5250PT and its sibling. 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 as the classic design of any GermGuardian 28-inch tower air purifier. Granted, there are shades of the old PureGuardian air purifiers, from the curved top to the 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 purifier.

A new digital control panel with four function buttons will be attached to the top of this GermGuardian AC5250PT. 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 of the GermGuardian AC5250PT is its weight of 10.5 lbs. This air purifier can fit in any type 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. The GermGuardian AC5250PT once again uses the same 3-in-1 air cleaning system as the GermGuardian AC5000 with these unique Guardian Technologies’ 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 also includes an antimicrobial treatment to help prevent 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.

The GermGuardian AC5250PT is one of the most popular air purifiers from this brand, and for an apparent reason. This air purifier is the most affordable air purifier using the latest HEPA technology from Guardian Technologies. The company calls its air filter the 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 the GermGuardian AC5250PT has the same power as the latest devices from this brand, like the GermGuardian AC5350BCDAP4500BCA, or even the current CDAP5500BCA. The GermGuardian AC5250PT is one of the best air purifiers for mold and mildew because it uses an UV-C light bulb.

To test the performance, I chose the GermGuardian AC5350B and Honeywell HFD280B to compare with our GermGuardian AC5250PT. The following result appears to be repeated in any GermGuardian reviews, as both the GermGuardian AC5250PT and AC5350B had an extremely high efficiency of 99.9% of particles down to 0.3 microns. The Honeywell HFD280B, however, had a higher efficiency of 92%.

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

GermGuardian AC5250PT Room Coverage

The GermGuardian AC5250PT can cover as much as its brother – the AC5000. The room’s coverage is 180 square feet. Also, other fan power indicator specs of the GermGuardian AC5250PT are exactly the same as those of the GermGuardian AC5000E.

The ACH of GermGuardian AC5250PT is 4X. These 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 surpasses the CDAP5500BCA a little bit.

GermGuardian AC5250PT Sound

One major difference between the GermGuardian AC5250PT and 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 on the market. For example, the AeraMax 300 is only 35 decibels, the SilverOnyx can be as low as 25 decibels, and the Winix 5300-2 is 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 the noise level of a public restaurant or an air conditioning unit at 100 feet. And this noise level is the culprit in many headache cases for users.

Again, we hold the opinion that you should keep the fan speed at a low setting while using the GermGuardian AC5250PT in quiet places like your office or bedroom. If you need a decent air purifier with quiet operation, we recommend checking out the Levoit Core 300S.

GermGuardian AC5250PT Power Consumption

A good air purifier must be used for a long time to be efficient, and 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.

Using the old 8-watt 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 for 8 hours per day, it would cost you up to $25 per year. It is not much more expensive than other air purifiers from this brand, so you won’t hate the GermGuardian AC5250PT too much if you have used many GermGuardian devices in the past.

GermGuardian AC5250PT Additional Features

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

This AC5250PT, however, lacks smart features such as a Smart Sensor and Wi-Fi capability. To have these features, you must save up for a CDAP4500BCA or CDAP5500BCA.

Our verdict

If you’re still undecided about which GermGuardian devices to buy, the GermGuardian AC5250PT is the one to get. This air purifier runs the most powerful fan from this brand and uses the latest HEPA filter technology from Guardian Technologies, all for $129. Especially due to the recent reviews of bad app connections, you should stay with the classic GermGuardian AC5250PT as long as the company doesn’t improve its flagships.
