GermGuardian CDAP4500BCA was supposed to offer cheap solution of air purifier running with smart features like Wi-Fi capability and Smart Sensor. That’s why this air purifier is – in reality, a CDAP5500BCA minus 6 inches in height so it can be put on a desk or table. Now, let’s dig deep in this GermGuardian CDAP4500BCA Review (it is also appropriate for the GermGuardian CDAP4500WCA Review).

GermGuardian CDAP4500BCA Price

This GermGuardian CDAP4500BCA is in fact sharing the same design and air filtration process with its taller brother, the GermGuardian CDAP5500BCA. As a result, the official price of this device in the United States and Canada is the same as that of its big brother, $249.

However, as a smaller one, you can find a good discount for this GermGuardian CDAP4500BCA, with a much more desirable price tag of $149. With a more attractive price, the GermGuardian CDAP4500BCA costs you as much as the GermGuardian AC5350B, but with more Smart features.

For $149, this GermGuardian CDAP4500BCA is the most affordable Smart air purifier you can purchase these days. There is no alternative option with such generous features; for example, the Honeywell HFD-120-Q, Coway AP-1216L and SilverOnyx are great but lack Smart Wi-Fi connectivity. We have the TCL Breeva A3 and Levoit Core 300S, both of which are ready to deliver better performance than our current unit.

Moreover, if you click on the link below, we will offer you a much better deal. Interesting?

GermGuardian CDAP4500BCA Design and Size

As we stated earlier, you are looking at a smaller version of CDAP5500BCA. And this air purifier has a White version, which is named GermGuardian CDAP4500WCA. If you are looking for a GermGuardian CDAP4500WCA Review, you are in the right place to read it.

That means GermGuardian CDAP4500BCA shares all its features with the bigger brother. Design-wise, this air purifier stays in a black onyx color, making it more beautiful and unique for the brand.

The front of the device still has a circular light to indicate the current air quality in your room. GermGuardian names its Smart Sensor function the Smart Air Quality Monitor (or AQM).

Also, you will find on the back of the GermGuardian CDAP4500BCA an air intake grill. Clearly, I don’t like the position of any modern GermGuardian air purifier. It makes me uncomfortable thinking about where to put this air purifier. However, as a much shorter version of the CDAP5500BCA, this air purifier can be easily put on a desk or a side table.

As usual, we will have a modern-looking control panel at the top of the GermGuardian CDAP4500BCA.

While there’s nothing particularly noteworthy about the way the GermGuardian CDAP4500BCA looks, it is a perfect small device for personal use, with only 9.45 lbs. Do you require an air purifier to be placed anywhere in your home? Voila.

GermGuardian CDAP4500BCA Filters

As the most important criteria to the air purifier’s power, basically we will search for how many filters it has and the air filter types are used. Being one of the latest GermGuardian air purifiers, the GermGuardian CDAP4500BCA introduces a 4-in-1 air cleaning process as below.

1. Pre-filter – This filter is a decent pre-filtration when combined with an activated carbon filter. As a result, this air filter can remove any large objects of pollutants and odors caused by smoke, cooking, and pets.
2. True HEPA filter – GermGuardian CDAP4500BCA experiences the same True HEPA technology as the latest devices from Guardian Technologies, which capture 99.97% of particles as small as 0.3 microns, including allergens, dust, and mold spores. This filter includes an antimicrobial treatment to help prevent any odors or bacteria from getting trapped in the filter.
3. UV-C Light – This filter is great at killing airborne bacteria, viruses and mold spores that cause health issues by altering the genetic structure of the germ.

There is not much to say about the traditional set of air filters in a GermGuardian one. You will have the most recent GermGuardian True HEPA filter technology, with 99.97% allergen filtration down to 0.3 microns. In standard conditions, this filter-B HEPA is as good as the latest filter-C from the same brand.

The efficiency of this GermGuardian CDAP4500BCA is the same as that of the taller version, the GermGuardian CDAP5500BCA. The GermGuardian CDAP4500BCA can capture 99.9% of particles as small as 0.3 microns in the same test conditions of a 100-square-foot room for 1 hour.

The bottom line of this powerful air filtration process is the UV-C light air filter. Using a low-power UV bulb, the performance rating of this UV light can match any other GermGuardian products.

Being the smaller model of this brand, the GermGuardian CDAP4500BCA uses the same filter as the AC4300, AC4825, AC4900CA. This air filter B is much more affordable than the latest filter C, with the same filter duration of 6-8 months.

GermGuardian CDAP4500BCA Room Coverage

GermGuardian CDAP4500BCA is truly a small air purifier for small rooms. Guardian Technologies makes this device for a modest room size of 153 square feet.

The ACH of GermGuardian CDAP4500BCA stays at 4X. This air changes per hour rating is decent for the room size of 153 square feet.

Also, the CADR of GermGuardian CDAP4500BCA is 107 Dust/ 99 Smoke/ 116 Pollen (cfm). If you choose the GermGuardian CDAP4500BCA, you will have nearly the same fan power as the CDAP5500BCA for less than $50.

GermGuardian CDAP4500BCA Sound

The noise level of this GermGuardian air purifier machine, like that of any other GermGuardian air purifier machine, is not a competitive advantage. But the GermGuardian CDAP4500BCA is no different. At its loudest setting, it makes a lot of noise. However, you can clean the air filter regularly to significantly reduce the noise.

The noise level for this GermGuardian CDAP4500BCA is not stated anywhere in its manual. Through rigorous tests, I have measured a stable lowest noise level of 40 decibels (dB), 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. The SilverOnyx has a noise level of 25 decibels, and the Winix 5300-2 has a noise level of 28 decibels.

At its highest setting, the GermGuardian CDAP4500BCA is not suitable for any quiet areas, particularly your bedroom. The noise level is measured at 55 decibels (dB), and this is the noise level of a public restaurant, something that can irritate a person’s headache.

GermGuardian CDAP4500BCA Power Consumption

A good air purifier must be used for a long time to be efficient, and in Breathe Quality, I’ve been asked many times, “Do air purifiers use a lot of energy?” We believe that power consumption is one critical factor in deciding if this air purifier is good or not.

With a 5-watt UV-C bulb, the GermGuardian CDAP4500BCA consumes a reasonable amount of energy, with a rated power of 52 watts. This is still higher than normal power consumption, but it is quite better than other well-known devices like the Winix 5500-2 or Winix WAC9500.

For using a GermGuardian CDAP4500BCA for 8 hours per day, it would cost you up to $19 per year. I don’t say it isn’t reasonable for a common air purifier, but as a small Energy Star air purifier, I expect a less energy-consuming performance from the GermGuardian CDAP4500BCA.

GermGuardian CDAP4500BCA Additional Features

As the smaller version of the well-known CDAP5500BCA, the GermGuardian CDAP4500BCA features the same additional features as the high-end models of Guardian Technologies. You will have a true Wi-Fi smart air purifier with an astonishing price tag of only $150. Using your smartphones with both Wi-Fi and Bluetooth, you can easily control and monitor your air purifier settings. Only the Honeywell HPA250B, Blueair Sense+ and Levoit LV-PUR131S can have this function, but they are more expensive than our GermGuardian CDAP4500BCA. Not anymore; the Levoit Core 300S and TCL Breeva A3 are the best smart air purifiers at the same price point as the GermGuardian CDAP4500BCA.

Yes, you can make use of Alexa voice commands. However, I am really disappointed with the bad connection with Alexa on another GermGuardian air purifier. It seems the company had better not add this smart function. GermGuardian CDAP4500BCA may be better.

Luckily, you will be happy with the Smart Sensor of GermGuardian CDAP4500BCA. You no longer need to manually control your air purifier because the Smart Sensor function will adjust the fan speed based on the current environment level. Just so you know, this function is mostly found on high-end air purifiers.

GermGuardian CDAP4500BCA Customer Service

There is not much to say about the brilliant support from Guardian Technologies’ customer service. Anyone can get active support from the American brand. The company also makes the instruction manuals available online to help you answer common questions on your own. But if you can’t find a solution, just contact customer service via phone at 866-603-5900 or via email at support@guardiantechnologies.com.

You can register for a warranty for up to five years.

For the GermGuardian AC4825, GermGuardian AC4900CA, GermGuardian AC4300BPTCA and GermGuardian CDAP4500BCA, you will have a 3-year warranty.

Our verdict

If you are a fan of GermGuardian, you may easily fall for this GermGuardian CDAP4500BCA air purifier because it has the same performance rating as the latest device but a much more affordable price tag. Though the Wi-Fi Smart feature is not actually good, this air purifier is still great with a powerful air filter process and an accurate Smart Sensor. However, we honestly advise you to stick with the lower models of GermGuardian, like the GermGuardian AC4300BPTCA, GermGuardian AC4900CA, or GermGuardian AC4825.
