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 to buy the wrong product from their stores if they really want. GermGuardian AC5300B has nearly everything to be mistaken with the latest tower air purifier – CDAP5500BCA, with a pure plastic GermGuardian’s design. This could be the best way to make a GermGuardian AC5000 model look more expensive and beautiful.

From the front, this style is truly the last year’s style of GermGuardian, with a circular light to indicate the current air quality in your room.

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

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

This unit is really light-weight with 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.

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

With an addition of an UV-C light bulb, the 3-in-1 air cleaning system from GermGuardian is still formidable in capturing and killing the 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 CDAP5500BCA, AC5250PT, AC5000, AC5350B. That means you don’t need to pay an extra of $70 to use the best air filter of Guardian Technologies. It should also be noted that today Guardian Technologies has two layers of True HEPA filter for different purpose. The last but not least, you need to change the air filter every 6-8 months base on 24/7 use.

GermGuardian AC5300B Room Coverage

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

The ACH of GermGuardian AC5300B is 4X. This air changes per hour rating is similar in all tower air purifiers of this brand.

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 with the GermGuardian CDAP5500BCA.

GermGuardian AC5300B Sound

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

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

If you are planning to have an air purifier for a quiet space, GermGuardian AC5300B is okay, but not the best choice of yours.

GermGuardian AC5300B 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.

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

For using a GermGuardian AC5300B 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 cost.

GermGuardian AC5300B Additional Features

Don’t be deceived by the modern looking of 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.

This GermGuardian AC5300B is indeed a more affordable GermGuardian CDAP5500BCA with no Wi-Fi capability or any smart features.

For the price, Guardian Technologies prioritizes the technology in exchange of the weak fan power. So make sure to just choose this air purifier for personal use.
