A Must Have!


I've received this Big+Quiet BP03 last week, and I'm impressed.I am a fan of Dyson design and technology. I’ve been using a TP09 cool formaldehyde purifier, three vacuums and a hair dryer. My husband and I have allergies, using a purifier fully sealed with HEPA filter, really makes us feel better. We love that it creates more indoor air circulation. Living in the west coast where some years affected by wildfire smoke, having a good purifier added a second layer of filtration aside from the house HVAC system. This new BP03 is surely a step up in quietness. It shows the actual number of HCHO in mg/m^3 that goes up or down in real time. I also like the design, it reminds me of r2d2 robot with its can-like body. It is bigger and heavier than TP09, but I can easily move it across the floor - it has wheels underneath.
