“I tested it with kitchen odours while cooking, and within about 20 minutes of running the air purifier, I could smell little to nothing. I find that astonishing. I've used other air purifiers before, but this one does the trick.”

Product is exceeding our expectations one month in!

There needs to be more colour options for a premium service marketed to be displayed not hidden. The dark blue doesn't really work in modern or midcentury decor. A true black or charcoal would have been a better choice. The fabric can be charged, yet the device itself is still blue.
Also we question if it's working properly. For some reason the TVOC spikes from 50 to 400+ a couple times a day, often while nothing is happening in our condo. No cooking, no windows open, ... weird.
BUBlueair UK2 days agoThank you for taking the time to share your thoughts. We understand how important color and finish are for a product that’s meant to be visible in modern or
mid‑century spaces. We’ll share your feedback with our product team as they evaluate future design options.Regarding the TVOC spikes you’re seeing: the sensor is very sensitive and can detect particles down to 0.1 micron, so it can register changes from sources that aren’t always obvious. For example, cleaning products, off‑gassing from furniture or paint, or variations in outdoor air. Our support team will reach out to you directly to assist you further.

I bought this for an open space area in an apartment. I’ve enjoyed having it, especially when cooking with strong odors or the room gets smoky. It was a little tricky connecting to my WiFi, but glad I did. I set it on auto most days. Now when I start to cook certain things, I turn the fan to 4 for extra circulation before getting started. Overall, it’s quiet and helpful.
