BEST INVESTMENT! LOVE THIS DIFFUSER
This is by far the best investment I have made to make my home smell good all the time. I’ve tried everything from plug ins, candles, wax melts sprays you name and it would last 1 week if that and then nose blind or it just wouldn’t be as powerful. I had purchased another diffuser not this brand, but sent it back because it was loud and didn’t work if my phone was not nearby. I decided to pay alittle more and try this one. AMAZING! first off it connects to my wifi and I control it through the app from anywhere. Very easy to setup for me. It took me awhile to adjust it to the perfect setting though but that’s normal I didn’t want the scent over powering nor too little so you have to play with it for awhile. It is a quiet machine compared to the one I had tried out, I can visibly see the mist and it fills my home with greatness. My house is a 2600sqft and it reaches to my second floor without connecting it to the HVAC. I notice the scent even comes into my office upstairs with the door closed. Im truly impressed and I hope it lasts me for a long time. I purchased a 4oz scent to try and see what scent I want for my house and let me tell you, it’s been over a month already and there is still scent in the bottle to last me awhile. I can only imagine how long it would last if I filled up the diffuser bottle to the top. I understand some people have had issues with theirs but I have not and am greatful. Thank you Aromad for finally making this product and I can throw everything else away! I only need this in my home.

A great way to evenly dispense scent throughout the house, without a bunch of wall plugs
I bought this to use in our 2400 sq ft home with 1 AC unit and 2 zones. I have added the machine to the main blower area and whichever zone is blowing will get the scent. It works great, I have had to adjust the settings to increase the spray time and increase the time between sprays. The house smells great on both zones. It does take some adjustment to get it just right, but once you get the right timing, it does help spread the scent evenly throughout the house.To add it to the AC I had to drill into the box in my attic and place the hose in it. That was it. I ran power to my scent machine and setup the wifi settings to let me control it through the app. The app setup was simple. The only issue I had was every time you make a change, the unit will spray. It caused a lot of scent to be distributed initially. After that setup period, it was fine. The bottle holds a lot of oil in it. I think it’s strange they all have keys on them to lock the scent in, but I am just leaving the key in it. No one will go in my attic to adjust it.

Nice Addition To Our HVAC System
This device feels like it is of good quality and well constructed. I secured this onto the HRV, tying into the duct going into the house. All of that was a breeze. Programming from the unit is fair, but the app makes it a lot easier.There is a massive bottle (600 ml) inside to hold fragrances. I wish it had different-sized bottles during the install process. It seemed pouring 10 ml into a 600 ml container would have been wasteful. Contrary to my expectations, the oil did not settle at the bottom.It fills the house well. An HRV pumps air into specific areas of the house, not every vent. The scent is stronger in those areas of our house, though not overwhelming; it’s lighter elsewhere. The settings I use are: Sun – Sat, 12a – 11:59p, Work-10, Pause 240. One-10 mL bottle lasts about one week. I believe this duration is ideal for maintaining a noticeable, fresh scent.Delivery was prompt; packaging was great. I’m thrilled to have found and purchased this! We have two Shih Tzus. Although we make monthly visits to the groomers, they do smell like dogs after a week. Our house no longer smells like we have pets. Neither does it smell like pets mixed with fragrance.If interested, I purchased Arvidsson fragrances (six-10 mL set): Hotel, Floral, Fruits, and Clean. The Hotel set smells the best. I cannot pull myself away to try the others.I recommend this diffuser. Keep in mind that I have no plans to use it in tabletop mode.

Potential but falls flat
Edited: I am adjusting my review based on the service I received from the team for the product. I too own a business and understand the power of backing your product,And that’s exactly what they did. Did the product work? No. Does it have potential? Absolutely!I’m going to be honest as I don’t leave reviews. But I wanted to shout out to Cindy! The service person I was dealing with. Cindy was fantastic. See the product I bought was the upgraded Aromadd HVAC unit. It absolutely doesn’t work. (First one) Cindy helped me troubleshoot the thing and we found out the head unit was defective. Cindy got another one sent and unfortunately it worked for 20 mins and stopped working as well. So in retrospect Cindy if you see this. Your five star. The product has potential but obviously cheap parts and is not worth the premium price I paid. Thank Cindy for exceptional customer service

Top Notch Product Backed by Amazing Customer Care
Amazing Diffuser & Outstanding Customer Service!This diffuser has been such a great addition to my home, it works beautifully, looks stylish, and fills the space with fragrance quickly and evenly. I use it daily and absolutely love it. What really sets this product apart, though, is the customer service. When I lost my safety key, I messaged the company and they responded right away—and immediately sent me a replacement with no hassle at all. That kind of service is rare and so appreciated!I highly recommend this diffuser to anyone looking for both a quality product and a company that truly cares about their customers. Five stars from me.
