Funciona muy bien el regulador. Hace un poco de ruido cuando se pone al máximo; pero en modo bajo es bastante silencioso; y se ve claramente cuando limpia el ambiente, se observa el cambio de luz.

I bought one of these in October 2024 on the advice of a homeopathic doctor. I struggle with allergies, asthma, and damp weather exacerbated mildew in part of my home that was contributing to breathing distress. She recommended this unit as she used it around the office and personally in her own old, damp home. She said the smaller size also makes it easy to take with you on vacation or even move it around the house - in the living room when you're watching TV, in the bedroom as you sleep, etc. You can easily look up the specifics, but these units apparently are superior in the elimination of mold spores. I used this along with other protocol and experienced relief of my symptoms, but I have to note that I also took medicine, bought a better dehumidifier, etc. so it was one piece of a puzzle to better health. I don't want anyone to think I'm claiming it's a 'miracle' machine, but I do think it is a great addition to a plan to optimize your health, whether you have issues like me or not. I believe it works well as I've noted by its subtle detection of any changes in the air, and that it is beneficial to air quality.This machine is very quiet unless it amps up, which if you have it on 'auto protect', it will when particle levels rise in your home (around here that usually means my husband is cooking bacon, lol). If you don't want it to automatically accelerate, you can set it on any setting between 1 and 5, 1 being the slowest and therefore the quietest. Of course this also means that you can manually increase the speed (and noise level) with which it circulates the air.It's a well-built, sturdy unit, which I appreciate. The app is simple, easy to set up, and easy to use.I bought a second one on Black Friday sale in November 2024, and despite having 2 units running 24/7, I haven't noticed any increase in my electric bill.In my opinion these are great little units, but I hadn't written a review until now because the real 5 star moment came when the device I bought in November quit working properly. It registered very bad air quality and would only run on the highest speed, despite my other device humming along registering good air quality. I tried all the trouble shooting steps I could on my own (google's recommendations) with no change. Honestly anticipating a huge headache, I reached out to Molekule and received an email reply from a customer service rep named Denise. She gave me a series of things to check and do (they were easy-to-follow steps and afterwards, I was to wait 24 hours to see if the device would reset). When it didn't, I reached back out and received a prompt response thanking me for following the steps, confirming my need for a replacement, and sending me a shipping label (I had kept the original box). I returned it, and they very quickly sent me a new device! I am very pleased with their customer service's polite, prompt response that resolved my issue without any aggravation or hoops to jump through or stalling.Five stars for a really efficient, quiet, hard working air purifier & top notch customer service.

Very good! highly recommend! Very pleasant smell and cleans the air very fast! :) Even fragrances and smoke.

Picked this up on an Amazon sale, it’s great. Stays quiet, really nice white noise while sleeping, good app and it connects to AppleHomeKit so we can setup automations. But normally it just stays on in auto mode.

Después de tanto investigar y decidir comprar este purificador, una decepción ver que la app no funciona. El proceso para darlo de alta nunca funcionó. Contacté a soporte técnico y no me pudieron ayudar. Es una pena que un artículo tan caro tenga una app tan pobre. Es quizá la peor aplicación que he usado. Una pena pero lo voy a devolver. Todas las opiniones en el App Store y en Google Play Store dicen lo mismo. No gasten su dinero!
