“I had hoped to plug these 3 devices in and notice a quick improvement in air quality within my home. It's been a couple of weeks and I haven't noticed any reduction in allergens, a cleaner-smelling home, or anything really. Kind of disappointed. I also don't love the blue glow that is distracting to sleeping in the bedroom. And it's all around the edges, so I can't put a piece of black tape over it to make it darker.”
