Review on 🌬️ Germ Guardian Wi-Fi Bluetooth Smart Voice Control Air Purifier CDAP5500BCA, UV Light Sanitizer Eliminates Germs, Mold, Odors, True HEPA Filters Allergies, Pollen, Smoke, Dust, Pet Dander, 28-inch 4-in-1 by Lauren Lewis

I wanted a smart room air purifier with UVGI and HEPA filters that was certified low ozone. This one met those criteria, but some of the rest of the features weren't perfect. PROS: - HEPA filtration and UV-C disinfection - Smart app (plus Alexa/Google) - Particle sensor and display - Certified by the California Air Resources Board as a low-ozone fan - 5 speeds with automatic mode; Silence at lower settings. CONS: No washable pre-filter. The Alexa interface is pretty much useless. (Didn't try Google.) - No night mode and lighting too bright for a bedroom - Not UL2998 certified - Airflow is limited, entering at the side and exiting at the rear, meaning it cannot be placed next to a wall or piece of furniture and does not mix with area breathing. If you have a small but open non-sleeping space with no pets and a lot of dust, then this device is probably a good choice.
