You may be wondering, while on the hunt for the Best Air Purifier, whether you should be searching for the best plug in air purifier or the best UV air purifier. Have you stopped to consider that you should maybe be seeking both? The GermGuardian CDAP5500BCA boasts incredible air cleaning capabilities and is customizable to fit your needs.\r\n\r\nWhy We Like It - GermGuardian CDAP5500BCA\r\nThe GermGuardian CDAP5500BCA is yet another impressive showing by GermGuadian. The activated carbon filter, True HEPA Filter, and UV light all work in tandem to capture and eliminate contaminants of all sizes and varieties. And it can even be controlled via app or be voice commanded too!\r\n\r\nPower\/Speed\r\nGerm Guardian Technologies Tower Air Purifiers employ a charcoal filter (as a pre filter) with an activated carbon filter to remove large airborne particles for great air. Afterwards, a UV light with UV C Light Technology kills the small and large particles. If you like UV air cleaning technology, you can also check out the GermGuardian AC5350B.\r\nEfficiency\r\nBrand GermGuardian Air Purifiers have never really been known for their reach, and this clean air filter is no exception. Still, the 170 square feet it does provide is decent, and the room air quality will still greatly improve. Even the Hamilton Beach 04386A improves air quality in a room of similar size. Unfortunately, GermGuardian does consume quite a bit of energy, requiring 60 watts of power just to run.\r\nVersatility\r\nThe CDAP5500BCA\u2019s True HEPA Filter captures 99.97% microscopic allergens, dust, pet dander, and mold spores down to 0.3 microns. The GermGuardian also comes with five fan speeds so you can adjust it to whatever suits your needs. While this air purifier is great for pet dander, you can also check out the Germ Guardian AC4825E if you want one specifically for pets.\r\nDurability\r\nAt 11 pounds, the unit isn\u2019t exactly heavy, but it\u2019s also not the lightest we\u2019ve seen. Noise level, even at the lowest settings, is still loud too. You\u2019ll definitely notice some noise when it\u2019s on the highest settings. Filter replacement should occur anywhere between 6-8 months, but luckily GermGuardian provides some of the most affordable filter replacement.\r\nValue\r\nThe CDAP5500BCA is a smart air purifier that can be controlled via the wifi smart app. You also have the option of voice control, something not available in a large number of other air purifiers, because of the unit's compatibility with Google and Alexa. Finally, customer reviews are largely positive, scoring 4.5\/5 stars on Amazon which is always nice to see. It also boasts an air quality monitor so you can keep track of the air quality in the room.\r\nGermGuardian CDAP5500BCA Wrap Up\r\nThe GermGuardian CDAP5500BCA has the same negatives as most other GermGuardian air filters. They\u2019re noisy, and they consume a lot of energy. However, their air cleaning capabilities are virtually un-matched. For if you are willing to put up with these annoyances, you\u2019ll find a friend in this air purifier.
