Smart Scent Air Machine Pro for Home, HVAC Scent Diffuser for Essential Oils 850ML, Waterless Aromatherapy Diffuser Cover Up to 4500 Sq.Ft

So I tried 3 other brand diffusers before getting this one on Prime Day's.  My experience for the other 3 diffusers was bad.  One dripped all the time, another one was not strong enough and the third one had a buggy bluetooth app.  I grabbed this unit on Prime Day's and have been nothing but happy with it.  It came packaged very well with an extra big tank.  The unit has a nice look with everything concealed behind the door.  The app works very well and had it up and running in 5 minutes.  The one thing I like about the app is it tells you how many days the oil will last by your settings.  I am renting now and use it as a standalone unit, but this unit will also work when I buy a house and install it to the HVAC system at 4500sf.

In my house there is always some type of candle or warmer going to add a scent to the air, now this is great but... it generally doesnt work for long because someone opens a window or a door and then poof out goes the nice smell. Now add to that that candles - even with a warmer really are just hot smelly wax, and if one happens to get knocked into you have a hot wax mess that has to be cleaned up, not to mention the actual fire hazard if you light one.This is your solution, now it will take a tiny bit of time to mount the unit to your furnace / air conditioner and you can buy scents on Amazon and you are done.. this has several very distinct advantages1) larger size refills mean the scent you pick lasts longer2) there is no messy wax or little tiny airwic refills that you have to always buy3) one scent for the whole house -- no more variations and or making sure you buy 10 airwic's4) you dont have to worry about an open flame5) works with AC or HEAT or just turn on the circulating fan. This is a great product - fairly easy to install ( read the instructions ) it DOES NOT come with a scent, but Amazon carries lots of varieties ( order at the same time so you can get it up and running right away ) The headline here is this is very well built, and after the initial purchase very economical to run and most importantly does a great job !

Just to clarify, this review is for the large version of the diffuser product. I just left the UPS store because I returned it . The product states that it covers 4500 ft.². Please note that many of the positive reviews on the product site are for very small inexpensive diffusers, and not for the large costly diffuser. They clump them together review-wise however the large version is a couple hundred dollars so it’s very different. My wife and I were excited to purchase this product and when it arrived we connected it to our HVAC system following the directions. Set up was easy. We have two floors in our house totaling 6900sq ft and we connected it to the 2000 square-foot floor HVAC only because we assumed that if it was designed to cover 4500 ft.² that it would work incredibly well at 2000 ft.² Unfortunately, within two days the LED screen broke. And was illegible. We were still able to change settings using the app which connects to the unit via Bluetooth. But This was really frustrating. I would’ve hoped that it would’ve worked for a long time . There are reviews stating that this has happened to others as well. Please note them. The second issue is that the diffuser only puts out scent at a certain flow rate. The diffuser can be adjusted by changing how long the diffuser stays on, and how frequently it emits the scent but the flow rate is constant. So if you are pushing air through your furnace consistently. You are only getting a very dilute concentration of the oil and we could barely smell the scent in the closest rooms and we definitely could not smell it in the distant rooms. Remember, this was a 2000 square-foot area . You see Just because the machine is bigger and comes with a larger price tag, All that means is it has a larger reservoir bottle. it does not push the oil through the machine at a faster flow rate. So, the amount of fragrance you get through all vents throughout the system is going to be very minimal. Overall this machine doesn’t really work well and the machine is very poor quality, it was quite a disappointing purchase. And I absolutely could not recommend it. And, if you are thinking that you were going to use it to connect it to your HVAC and make your house smell like a hotel all the time like we did, you will be very disappointed. Look elsewhere. I hope this review leads you to a better product .

The media could not be loaded. I did a lot of research before purchasing a cold air diffuser. I was originally looking at the Aroma 360 (the hotel version) and couldn’t justify spending $1,000+ on an item with mid reviews.I came across this one, with many good reviews and I especially was drawn to the reviews that mentioned open concept and 2 stories as that is what we have. Our home is a 2500 sq foot 2 story & wanted something that was HVAC ready & waterless. For the price, I figured it was worth a shot, I am so glad I bought it! I needed something that would lighten the life scents we bring into our home; we have 2 teenagers 😂 plus a few pets.We’ve been using this for a few days now & the machine is fantastic. It was easy to set up, the app works great & it’s very quiet! It holds a large amount of oil, no residue and the timer is awesome. Custom dosing the mist to what is needed & love that you can set a schedule within the app.I did purchase Levona oil to use, it’s cold air oil & the scents are perfect! Very clean oil & not overpowering.
