Waterless Essential Oil Diffuser for Home and Commercial Use, Up to 2000 sq.ft. 400 mL Capacity, Aromatherapy Scent Diffuser for Large Rooms, Smart Scent Air Machine, Difusor de Aromas, ANW-White

Very good waterless air diffuser.
I’ve been using the Airversa Waterless Essential Oil Diffuser for several days now and so far it works very well. I use it in the bedroom so I keep it on lower settings so the scent isn’t so strong. There’s a sticker on the device that warns of possible sleep interference but I use a white nose machine and can’t hear a thing. Even with the noise machine off I personally don’t find it loud at all there’s just a little humming. The pictures are a little deceiving on these devices. The first one I bought I thought it was going to be rather big but these are actually very compact little devices, with the right placement it won’t be very noticeable. It also comes with a handy little wall hanger so you don’t have to take up shelf place if you don’t want to. Also these devices don’t use nearly as much oil as I thought they would, a little goes a very long way. A small bottle of oil lasts months and as someone who has used the candles, melts, plug-ins, and regular water oil mix diffusers these are a world of difference. These are truly set and forget.The app is very intuitive to use and there should be no learning curve for anyone. There was no craziness getting it connected to my phone at all. I installed the app and there was my device. The schedules are very easy to set and you can set 5 of them. It comes with a 400 ml bottle that’s about 13.5oz. One near thing in the app is that you can set a reminder for however many days to operate before cleaning the bottle and changing the oil, 30 days is the manufacturer recommendation. One thing I thought was strange is that I can find no way to set the time in the app or on the machine, I’m hoping this wont become an issue in the future. When installing the app it pretty much demands precise location permission so maybe that’s what sets the users time.I have purchased 3 other waterless diffusers of a different brand around the same price as this machine and that is what I am comparing this machine to. This machine has no battery backup and will not function on batteries so it’s not really what I would consider portable. The cord is a thick (kind of stiff) cable about the size of a computer network cable connected to a power brick so if your power cable goes out it’s not as simple as grabbing a new micro/c USB cable and spare phone charger. A little added extra they send with the machine is a screw on cap for the bottle. I know this may not sound like a big deal but when it comes to cleaning out the bottle this little cap is very useful. Put the cap on and shake to clean the bottle. My other machines I just put my thumb over the bottle top and shake it and the pressure in the bottle sprays out a bit so I really appreciate the cap (you will to). Also it comes with 2 keys which (one) is needed to open the case to access the oil bottle. If you have kids this will be a plus for you keeping little ones out of it. Personally I just leave my key in the slot.So just to boil it down.Pro’s:1. It Isn’t very loud2. The case locks3. The app is very intuitive4. Instant connection with the app5. It works very well6. Multiple schedules to setup7. It comes with a bottle cap for cleaning8. It has a large capacity bottleCon’s:1. Oversized/outdated power cable and brick2. No battery backup or operation3. Cannot set or adjust time/date4. Demands precise location permission on your phone/tablet5. The power light is a little annoying but a small piece of tape fixed that.As you can see the pro’s greatly out weigh the cons. I am very happy with the Airversa waterless essential oil diffuser. I think the price should be a little lower just based on the outdated power cord and no battery backup but if you can get this on sale it is well worth the money and I can’t imagine anyone being disappointed with this device. When it goes on sale I will probably get another one just for a backup or emergency gift.

Amazing
Smells and works amazing . Gives your home an amazing smell all day. Must buyI’ll be buying my second one for my basement area.

Easy & Great
Easy, sleek, long lasting, relatively quiet running, timed scent excellence! The app you download to program schedules, etc. is so easy & smooth- I would’ve never thought! From start to finish the whole process literally took maybe just 5-8 minutes tops. This unit comes with several unit locks, mounting screws, adhesive wall unit attachments to hand the product, a 400ml max essential oil decanter made of noncorrosive polymer, & a decanter cap in case you need to suspend your use for any use, you have a cap to maintain the integrity & freshness of your essential oils. My singular grievance that could very well be chalked up to ill-placement of the unit & or perhaps different essential oils, is that even with a few minor adjustments to scent dispersement schedules I can’t really smell my home “filled with aroma”. At best, I have to be moderately in close range to the unit closely after a mist has just been released to smell the essential oils. I will proceed with moving this unit to different parts of my home to see if I can make a difference; if that isn’t the problem, I’ll order some essential oils from the company that sells this product & go from there. The unit is relatively quiet when it disperses your desired scent and is comparable to that of your phone being placed on silent and vibrating mildly against a flat surface for just a few seconds- if that loud at all because it is really a light & soft sound. The product is noted to aromatize up to 2,000sqft or more, & lets you do the guesswork on the math of getting your mist schedule & misting duration time set up to your liking. For reference my starter home is well under 2,000sqft. & I have my schedule now set to go on every five minutes with a 10 second essential oil dispensing time, & I set the unit to run from 9am-10pm(shutoff). I’d guess a full oil decanter should last you around a month or more, but you will be able to configure that for yourself with handy Bluetooth/app which you can set with a “refill reminder” so you can always be ready to refill. The product states that every 60/90 days you should run *nothing but 90% isopropyl alcohol through the decanter to give a good clean cycle function to prolong the life of your product & also for clearing out old oils of your planning on switching scents. This unit also does not come with plastic corrosive safe tubing for HVAC installation so, this is strictly a unit for around your home.
