Molekule Air Mini Room Air Purifier

First, what I like about this: it's attractive, relatively easy to set up, and seems to be well manufactured.Now to what I do NOT like:- Filter life: what they do not tell you is that their 6 month recommended replacement interval is actually a requirement. I used my Mini when I first bought it a couple of times, then for some remodeling reasons it got unplugged and put in the corner. 6 months later, I turned it on again, basically brand new, and the filter LED was red and it wouldn't work. How could this be? The filter has been used maybe a total of an hour?! So I contacted Customer Service, and while they're looking into it, and it may get resolved somehow, what i learned from them is that as soon as their PECO filter is exposed to the UV light inside, it starts degrading. ANd it only lasts 6 months. So what this means, is that regardless of how often you use it, they're essentially forcing you to change this filter every 6 months in order to keep using the product. That is just BAD product design, and borderline unethical. At a minimum, this should be made very clear to purchasers, that you're signing up to buy their expensive filters and replace them every 6 months if you plan to run this rather expensive little device.- Aggressive Marketing: I downloaded the app, and I had to persistently click "NO" to avoid signing up for filter service. It's very clear what they're trying to do - they want you to put recurring filter sales on your credit card, so you will hopefully forget about it, and they'll get this lovely recurring revenue from you every year. Their Marketing team must be cackling with delight looking at their filter signup data. BEWARE. Also, I've seen aggressive online ads before, buy they are ridiculous. After I bought my Mini on Amazon, I was haunted by Molekule emails and online ads everywhere I went on the internet!! Advice... after reading this, and clicking away from their product page, clear your cache, delete your cookies, etc or you'll have a Molekule tail forever.- Questionable Performance: I've done a lot of research into PECO, UV and ionization related technologies, and while they work ok in lab settings, in real world tests the results are questionable at best. The reason is that for all of these, to be effective the all need a lot of time immersed in the light, or rely on particles in the air floating around hopefully attaching to bad things and neutralizing them. Like shooting a bullet with a bullet. They make it sound like they've solved the world's air problems. Do your research, read third party tests and reviews.... honestly, I think we're all better off taking the $400 plus $100 a year filters and buying a decent HEPA air purifier with activated carbon, and cheap replacement filters, and call it a day.In short, don't take their slick marketing and fancy science words at face value, do some homework.
