GermGuardian AC5300B Price

Using the old air filtration technology from GermGuardian, the GermGuardian AC5300B is even more affordable than the famous low-range GermGuardian CDAP5500BCA. This air purifier has an easy price tag of $129, which is $10 higher than the previous GermGuardian AC5000.

Also, if you are sticking with this GermGuardian AC5300B, you can purchase it with ease with the deal below because the price is only $115.

That makes the GermGuardian AC5300B the direct competitor to two of our recommended air purifiers: the Blue Pure 411 Auto and Levoit Core 300S.

GermGuardian AC5300B Design and Size

Not like the upgraded GermGuardian AC5350B, this GermGuardian AC5300B has only one black version.

Guardian Technologies could easily deceive anyone into buying the wrong product from its stores if it really wanted to. The GermGuardian AC5300B is almost identical to the latest tower air purifier, the CDAP5500BCA, with a pure plastic GermGuardian design. This could be the best way to make the GermGuardian AC5000 model look more expensive and beautiful.

From the front, this GermGuardian looks just like the one from last year, with a round light that shows how clean the air is in your room.

The intake air grill is the same as on GermGuardian air purifiers. The airflow will be polluted from the back and fresh from the front. With a 28-inch tower air purifier like the GermGuardian AC5300B, it is quite difficult to maximize the efficiency of this air purifier. If you want to know why, you can read about it in the previous CDAP5500BCA review.

At the top, the control panel is not as modern as the latest CDAP5500BCA, but it is still useful with 2 buttons and a LED filter replacement indicator.

This unit is really lightweight at 11 lbs. It is possible to move the GermGuardian AC5300B anywhere in your home.

GermGuardian AC5300B Filters

To decide the power of an air purifier, basically we will look at how many filters it has and air filter types are used. GermGuardian AC5300B is basically the classic GermGuardian AC5000E with only a typical 3-in-1 air cleaning system.

  1. Pre-filter – A normal 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 AC5300B 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.

The GermGuardian AC5300B is running a 3-in-1 air cleaning system from GermGuardian, which isn’t the latest technology from this brand. But it is indeed very similar to the latest GermGuardian 4-in-1 air cleaning system. We have tested both the classic GermGuardian AC5300B and the modern GermGuardian AC5000 in standard conditions, and it is safe to say these two devices pass the testing criteria easily. They all trap 99.9% of particles as small as 0.3 microns with impressive efficiency.

With the addition of an UV-C light bulb, the 3-in-1 air cleaning system from GermGuardian is still formidable in capturing and killing allergens like dust, dust mites, pet hair, pet dander, bacteria, mold, and fungi.

Remember that you can use the same filter in previous models like the CDAP5500BCA, AC5250PT, AC5000, and AC5350B. That means you don’t need to pay an extra $70 to use the best air filter from Guardian Technologies. It should also be noted that today Guardian Technologies has two layers of true HEPA filters for different purposes. The last but not least, you need to change the air filter every 6–8 months based on 24/7 use.

GermGuardian AC5300B Room Coverage

A typical GermGuardian air purifier is mostly suitable for rooms with a coverage area of less than 200 square feet. As a classic from the brand, the GermGuardian AC5300B will hold up to 167 square feet.

The ACH of GermGuardian AC5300B is 4X. This air changes per hour rating is shared by all tower air purifiers from this manufacturer.

The CADR of GermGuardian AC5300B is 114 Dust/ 108 Smoke/ 127 pollen (cfm). This CADR rating of the $129 air purifier is exactly the same as the GermGuardian CDAP5500BCA.

GermGuardian AC5300B Sound

Using only 3 fan speeds, the GermGuardian AC5300B reduces most of the noise level created by the highest setting in a GermGuardian 5-fan-speed air purifier. However, we still notice a noticeable sound when using the GermGuardian AC5300B at full fan speed.

Even at the lowest setting, the noise level of the GermGuardian AC5300B can reach 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 AC5300B 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. I bet most of our beloved readers won’t find this noise level acceptable.

If you want an air purifier for a quiet environment, the GermGuardian AC5300B is a good option but not the best.

GermGuardian AC5300B 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.

With a new built-in 5-watt UV-C bulb, the GermGuardian AC5300B consumes less energy than its predecessor, the GermGuardian AC5000. The power consumption is recorded at 54 watts, which is much higher than the energy-saving air purifiers like the AeraMax 200, Levoit LV-H132, Winix 5300-2, or Blue Pure 411.

For using a GermGuardian AC5300B for 8 hours per day, it would cost you up to $19 per year. Yes, for an Energy Star device, you could expect such low energy costs.

GermGuardian AC5300B Additional Features

Don’t be deceived by the modern look of the GermGuardian AC5300B; it is not the CDAP5500BCA with the latest additional features. You won’t have either Wi-Fi capability or the Smart Sensor. The only feature you will have is the necessary LED indicator for filter replacement. Well, better than nothing, right?

If you are truly in need of better additional features, you can pay up a little for the successor GermGuardian AC5350B, or save up for a real GermGuardian CDAP5500BCA.

Our verdict

This GermGuardian AC5300B is indeed a more affordable GermGuardian CDAP5500BCA with no Wi-Fi capability or any smart features. Instead, this air purifier is only for those who focus on the air filtration process and the performance rating. For the price, Guardian Technologies prioritizes the technology in exchange for the weak fan power. So make sure to just choose this air purifier for personal use.
