GermGuardian CDAP4500BCA review

Very attractive price (after discount) for a Wi-Fi enabled air purifier.
Able to adjust the air purifier fanspeed, mode or timer at any part of the world.
Flexible timer and Auto mode setup where you could set it through the physical button on the machine or via GT app.
"Real" True HEPA filter that able captures microscopic airborne particles and allergens.
Optional UV-C light does well in killing odor-causing bacteria and germs.
Standard GermGuardian 3 years manufacturer warranty.

Filter replacement cost could shot up high on heavy use (bad indoor environment).
Rather constricted purifying coverage which is only suited for small room size.
GT app unexpectedly shut down couple of times although updates would probably fix it.
Limited Alexa command while each array commands is overlong e.g. Alexa, ask Gi Gi to set the fan speed of Bedroom to 4.

Exciting times ahead for GermGuardian products. GermGuardian CDAP4500BCA WiFi Smart 4-in-1 is the first air purifier in its lineup that featured a Wi-Fi connectivity pairing. Not only you can fully access the air purifier functionality like timer, fanspeed through its GT app, GermGuardian CDAP4500BCA WiFi Smart 4-in-1 is also Voice Control Capable through Gi Gi skill and Amazon Alexa. A simple command like “Alexa, ask Gi Gi to set the fan speed of Bedroom to 2” will automatically set the air purifier fanspeed to 2. Up front the seamless tower shaped design also comes with a SmartAQMTM (Air Quality Monitor) that will light up in Red when air quality is bad, yellow when air quality is so so and green when air quality is good. There is also a control panel with digital display which replicates all the controls available in the app. Rounding up on GermGuardian CDAP4500BCA WiFi Smart 4-in-1 exterior quirks and features, Energy Star and a 3 years manufacture warranty is standard that warrant a pretty solid build quality.

Airflow capability and purifying coverage

Unfortunately GermGuardian CDAP4500BCA WiFi Smart 4-in-1 is one of the weakest Wi-Fi enabled air purifier we tested due to its tower form and price factor. A tremendously efficient air purifier on restricted room size, the airflow distribution rate is actually very consistent regardless of which 5 speed you opt for. In general, GermGuardian CDAP4500BCA WiFi Smart 4-in-1 can be used in living hall but bedroom size would probably suits it best.

Moving on with the purifying capability, GermGuardian CDAP4500BCA WiFi Smart 4-in-1 4-stage filtration depth can covers all ground including odor caused by bacteria. The optional UV-C light works well with the True HEPA filter and Charcoal Pre-filter in trapping up to 99.97% of airborne pollutants and allergens within in its purifying radius.

Noise level and power consumption

GermGuardian CDAP4500BCA WiFi Smart 4-in-1 does not have the greatest airflow delivery rate so naturally noise level is also reflected accordingly. At the first 2 speed you can barely hear any fan noise. Third speed onward noise level gradually increase but still within a bearable level. Shifting to the electricity usage, you will not see any major impact on the electricity bills on standard utilization of GermGuardian CDAP4500BCA WiFi Smart 4-in-1. Electricity consumption is partially low to average depending on what speed the air purifier is kick in. For more energy-efficient management, you can rely on the Auto mode and SmartAQM to work its magic.

Final thoughts on GermGuardian CDAP4500BCA WiFi Smart 4-in-1

Rounding up, GermGuardian CDAP4500BCA WiFi Smart 4-in-1 is the exact mirror of other GermGuardian tower air purifier if you remove the Wi-Fi support. Since it share most of the tower air purifier advantages/ disadvantages, we highly recommend consider GermGuardian CDAP4500BCA WiFi Smart 4-in-1 over the others as the convenience remote control brings and SmartAQM with auto mode is highly justifiably for a little money top up.
