Review on 🐧 Crane Adorable Penguin Air Purifier: True HEPA Filter, Germicidal UV Light, 150 Sq Feet Coverage, 3 Speed Control & Washable Particle Filter by Popeye Knight

I've had it for two years. i love these guys Great as white noise, also works as a night light. I know they're working when I see dust collecting on a washable filter every month. Regarding customer service, I had an issue with the UV light not working. I determined (by replacing the lightbulbs) that it wasn't the lightbulb. We have ensured that the entire assembly is replaced within a reasonable time. That's good customer service, IMHO. Right now I'm having an issue with one of them making a noise that sounds like something needs lubricating. Before I contact customer service, maybe someone else had this problem and found a solution?
