GermGuardian AC4300BPTCA Air Purifier: Trusted Review & Specs

Every 28-inch GermGuardian air purifier has its own 22-inch sidekick. If you prefer the smaller version, you can find the CDAP4500BCA for the CDAP5500BCA or the AC4825 for the AC5000. And if you need the 22-inch version of the AC5300B, this brand will give you the special GermGuardian AC4300BPTCA. So why do we call this air purifier “special”? Let’s find out in our quick GermGuardian AC4300BPTCA Review right now to see the answer.

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

GermGuardian AC4300 ranks C in our air purifier ranking list. We give the biggest and most thorough database of air purifier reviews in the world.

GermGuardian AC4300BPTCA review
  • Good performance for the money with UV-C light and True HEPA filter
  • Modern design
  • Always has good deal
  • 3-year warranty
  • Quite noisy at highest setting
  • Lacks of Smart features

It’s easy to say that the GermGuardian AC4300BPTCA is like old wine in a new bottle. Actually, it has similar internals to the AC5300B and a new design that is identical to the latest CDAP4500BCA. And while it’s true that the GermGuardian AC4300BPTCA does not bring any superior air filtering innovation, it does represent a shift in strategy from Guardian Technologies. Now, it’s time for our GermGuardian AC4300BPTCA Review.

GermGuardian AC4300BPTCA Price

As a tradition, the 22-inch device will have a drop in the price of the bigger 28-inch GermGuardian air purifier. That’s why we can believe that GermGuardian AC4300BPTCA will be much more affordable than GermGuardian AC5300B. When this air purifier launches, it will stay at $119, the same price as the GermGuardian AC5000.

For the same price, you can check out Amazon’s Best Seller Levoit LV-H132 or the Biota Bot MM108. They lack the GermGuardian AC4300BPTCA’s signature UV-C light feature but have a different airflow structure. The latest GermGuardian AC4200 should be a better alternative to these competitors than our current unit.

Also, we always try to give our readers the greatest deal, so if you follow our link below, you can purchase this GermGuardian AC4300BPTCA air purifier for only $119, or maybe even lower.

GermGuardian AC4300BPTCA Design and Size

As you may already know, the GermGuardian AC4300BPTCA looks identical to the CDAP4500BCA. There is no white version of this air purifier, making it easily mistaken for the latest device from Guardian Technologies.

GermGuardian AC4300BPTCA will be only 22 inches in height. As someone who’s been putting the GermGuardian 28-inch tower air purifiers on the floor, using the GermGuardian AC4300BPTCA made us bend down to press the button. It is ridiculous at first, but with only 9.45 lbs, you can easily put this air purifier on a side table.

Just like the AC5300B, the GermGuardian AC4300BPTCA displays a circular light on the front. Also, from the back, you still have an intake air grill. The GermGuardian AC4300BPTCA air purifier features the same airflow as others from this brand.

At the top, the control panel is the same as its bigger brother, with 2 buttons and an LED filter replacement indicator.

GermGuardian AC4300BPTCA Filters

We will look at how many filters an air purifier has and the types of air filters it uses to determine its power. The GermGuardian AC4300BPTCA is powered by the same 3-in-1 air cleaning process that’s inside the AC5300B, AC5000, and AC4825.

  1. Pre-filter – It’s the same pre-filter as GermGuardian AC4825. It combines with an activated carbon filter to remove the large particles of pollutants and reduce odors created from smoke, cooking, and pets.
  2. True HEPA filter – GermGuardian AC4300BPTCA also uses a True HEPA filter to capture 99.97% of allergens, including pet dander, dust mites, and pollen as small as 0.3 microns in size.
  3. UV-C Light – An UV bulb is also used in this air purifier to kill airborne bacteria, viruses, and mold spores.

There are no key differences here; GermGuardian AC4300BPTCA’s True HEPA filter is the same filter-B as this brand, meaning this air purifier performs as well as GermGuardian AC4825 or GermGuardian CDAP4500BCA.

With the addition of an UV-C light bulb, the 3-in-1 air cleaning system from AC4300BPTCA is great at killing mold, viruses, and bacteria.

One more thing to remember is that you need to change the air filter every 6–8 months based on 24/7 use.

GermGuardian AC4300BPTCA Room Coverage

GermGuardian AC4300BPTCA’s room coverage is a bit less than others of this brand, with only 153 square feet. It is still bigger than Levoit LV-H132 or Blue Pure 411, though.

The ACH of GermGuardian AC4300BPTCA is still 4X. This air changes per hour rating is stable and powerful enough to clean a small room.

The CADR of GermGuardian AC4300BPTCA is 107 Dust/ 99 Smoke/ 116 pollen (cfm). GermGuardian AC4300BPTCA has the same CADR rating as the flagship 22-inch CDAP4500BCA.

GermGuardian AC4300BPTCA Sound

With only 3 fan speeds, the GermGuardian AC4300BPTCA runs with less noise than most air purifiers from this brand. We only notice an apparent noise level at the highest setting.

Through rigorous tests, I have measured a stable lowest noise level of 40 decibels, which is higher than most other normal air purifiers in the same price range. For example, the AeraMax 200 and AeraMax 300 can reduce the noise level by as much as 35 decibels. You will also find the SilverOnyx with 25 decibels, or the Winix 5300-2 with noise level of only 28 decibels.

And when you switch to the highest setting, the noise level of the GermGuardian AC4300BPTCA can reach as high as 55 decibels (dB). This noise level is quite common in the world of air purifiers, but for an air purifier with low fan power, it is quite unacceptable.

If you plan to run this GermGuardian AC4300BPTCA in quiet places, make sure you don’t switch it to the highest setting.

GermGuardian AC4300BPTCA 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 same 5-watt UV-C bulb as the AC5300B, the GermGuardian AC4300BPTCA consumes even less energy than the GermGuardian AC4825 or the GermGuardian AC5000. We recorded that the power consumption of this air purifier is only 52 watts.

For using a GermGuardian AC4300BPTCA for 8 hours per day, it would cost you up to $19 per year. It is reasonable for an Energy Star air purifier, but you can find many others with much lower power consumption, like the Blue Pure 411, Levoit LV-H132, SilverOnyx, or AeraMax 100.

GermGuardian AC4300BPTCA Additional Features

Like its brothers, the GermGuardian AC5300B and AC5350B, the AC4300BPTCA comes with no additional features other than a filter replacement indicator. Yes, this air purifier does not even have a timer.

If you want more features, you should expect to pay up to $50 for a Wi-Fi-enabled CDAP4500BCA air purifier.

Our verdict

Just like the GermGuardian AC5300B, the GermGuardian AC4300BPTCA changes from the GermGuardian AC4825 with only a new appearance. We might think it’s unreasonable to pay an extra $20 for this new look. However, in most cases where we use this GermGuardian AC4300BPTCA, it is still a good air purifier, provided you can live with a smaller size air purifier, which is ultimately a matter of personal preference.

A good air purifier, but an increase of $20 for a modern appearance with GermGuardian AC4825 makes GermGuardian AC4300BPTCA ridiculous.
