You may have seen the Molekule air purifier show up in your social feeds lately. It’s a really slick, really expensive machine that makes some strong claims about its ability to purify air. Well, we’ve been testing air purifiers for years at Wirecutter, and in our trials, the Molekule fell short. By a lot. Here's how.

    You completely destroyed my interest in this thing. My wallet thanks you

    Who else had an ad for the Molekule before this video? At first I thought it was the Wirecutter setting the video up, but Molekule actually paid to put it there. Ouch!
  • I’ve seen a bunch of you tubers talk about this thing and how much they love it. Just goes to show if you make a fancy looking product and charge a lot of money, there are plenty of suckers in this world to buy it.
  • @milkmayun
    So like any other product that ad targets me on Instagram, it's overhyped and overpriced.

    The gentle way he is holding the Coway in the end

    I tried it, and it did absolutely nothing to help my allergies. I will say that the Molekule people were gracious and made it easy to return, which I was very happy to do.

    If you’ve never used an air filter these are great. youtube.com/post/Ugkx_dppjvjF8BYEmPSDTcgCUdRsgWYLX… I ended up with three after starting out with one. The noise level depends on the 1-3 settings with how hard you want the machine to work. You can also upgrade the filters and get one better for pet hair and smells which is a must have in my home. I noticed the air seemed lighter and easier to breathe when running the machine for the first time. Works great every time. Highly recommended!

    Well I think the spending on molecule must have looked something like this: Marketing 50% R&D 30% Design 29% Testing 1% Interface development 0%
  • @aokaze-minotaur
    Since the beginning, I have been saying that this was a fraudulent product, but nobody believed me. I'm glad someone actually tested it.

    The Molekule was what got me into buying an air purifier. After reading the science behind air purification, I ended up buying a $150 Hepa air purifier.

    Before this I watched a YouTuber pushing Molekule, going on & on & at the end says, “I can’t actually TEST the air quality as I don’t have any kind if meter” but this thing is the BEST air purifier. I have pets with serious asthma. Recently bought the Blue Air 411 & was getting ready to break my bank acct with the Molekule to try to do the best for my animals. Thank you so very much. Molekule’s website sounds like it will cure cancer, home school your kids and make dinner. I’m adding the CoWay. Many thanks!

    My husband wanted this particular brand. His logic? You get what you paid for. I said, spending premium price ($800) on an air purifier doesn't always mean you get what you paid for. Thank god I came across this review. We're looking into something else.
  • @Duffyyy94
    i couldn't stop laughing when they showed the price
  • That's the thing with Hydroxyl: it takes so much of it to destroy most particles that it can also damage humans. The solution is to pass the output through a screen that reacts with the hydroxyl, which the Molekule doesn't have. This missing feature could be why it works so poorly, or it could mean that this machine is a potential health hazard.

    I bought two of the Coway a few months ago after reading the Wirecutter review. They work great. Very quiet, I run them 24/7 on medium, sometimes putting them on high when I'm out of the house (if I remember, which I usually don't). I sleep with one on medium just a few feet away, it's a very pleasant and very smooth wooshing noise with no high frequency components.
  • @MulroePhoto
    is it legal for them to make these claims? jesus
  • @yeshuasaves7415
    You guys should test dyson's newest air purifier they claim it destroys formaldehyde
  • @zaugitude
    Thanks, I wondered about their extreme claims after seeing the ad many times.
  • @rionmartin9867
    Another fantastic review, Wirecutter! I was looking at the Molekule six months ago. Thanks to your roundup of air purifiers, I bought the Coway instead. It's been a great little machine.
