    • I Didn't Realize What I Was Missing!
Color: White Set name: U5
I've tried candles, plug-ins, and room sprays, but nothing compares to this diffuser. As soon as I set it up, my entire home smelled amazing. The fragrance is clean, elegant, and reminds me of walking into a luxury hotel. What I love most is that the scent is noticeable without being overwhelming. I work from home and spend a lot of time indoors, and this diffuser has completely changed the atmosphere of my house. Even my family and visitors have commented on how great it smells and have asked me what I'm using. The diffuser itself is easy to use, quiet, and looks great in my home. The oil lasts longer than I expected, which was a pleasant surprise. This is honestly one of the best purchases I've made for my home. If you're looking to make your space feel more inviting, relaxing, and luxurious, I highly recommend it. ... show more

    • Amazing!
Color: Black Set name: U5
I recently got the Aromadd scent diffuser and honestly love it. It makes the whole room smell clean and luxurious without being overpowering. The design is sleek and modern, so it blends in nicely with my apartment instead of looking bulky or cheap. One thing I really liked is how evenly the scent spreads throughout the room. It actually lasts for hours and creates a calming atmosphere, especially at night or while relaxing after work. It’s also super easy to set up and use. If you want your space to feel more cozy, fresh, and elevated, I’d definitely recommend this diffuser. Great quality for the price and makes a huge difference in the vibe of the room. ... show more

I absolutely love this scent diffuser! It has been a great addition to my space and does an excellent job of filling the area with a consistent, pleasant scent. The coverage is impressive, and it easily handles a large space without needing to constantly refill or adjust it. The smart features make it convenient to control, and the setup was simple. It feels like a high-quality product and has completely upgraded the atmosphere of my space. I highly recommend it to anyone looking for a powerful and reliable scent diffuser. ... show more

    • If you're on the fence.... BUY IT.
Color: White Set name: U5
I LOVE THIS THING. It fills the entire house with a gentle scent that makes every day feel like staying at a luxury hotel. I bought this specifically to install in my HVAC, but for the first few days I had it set up in my living room. It can fill a large room with scent in a very short time. It's beautifully designed and quiet. I was seriously considering just leaving it in our living room, but I really wanted the scent throughout the whole house. Installation into the HVAC and connecting to the app were very easy. I'm especially impressed with the customizable schedules within the app. You can toggle up to five different run times per day with different levels of scent, so I'm able to only have the machine running when I'm home so I can save on oil. I was worried about how quickly this machine would go through oil since it can be expensive, but I've been using it for 4-6 hours every day for the last month or so and have barely made a dent in the 500ml bottle of fragrance. If you're looking for an easy way to get compliments from everyone who visits, buy this machine! I wish I'd have gotten it sooner. ... show more

    • The best whole home fragrance system
Color: White Set name: U5
I don't write reviews often but this one is a game changer! I have a two storied house.That is roughly 2,400 sq ft. I typically keep my house very clean. But I have two dogs that are constantly running in and out of the house. So they tend to bring in grass, and they tend to smell somewhat musky when playing in the heat. I have installed this in the attic to my air handler which was very easy. At the lowest setting you can smell it the second you walk through the door. I get constant comments on how good it smells. Its always working in the background and I never have to touch it. I love it and would buy it again. I recommend this product to all my friends already. Its cheaper than having all those ugly plug in air freshener around the house which only smells when u are close to them. This item evenly distributes it among all the rooms so there are no dead zones. I highly recommend this to be installed in the air handler of the ac. Its the only true way to unlock its full potential. The casing is almost like metal and it's very sturdy and durable. The casing and the parts appear to have alot of longevity. They didn't cut corners when they made this. Best of all when I have guests coming over I can open my app up and boost up the scent a hour or 2 before guest to arrive to smell even better. It has a bright nice led screen with significant lighting for manual setting adjustments. Fyi.... to get the most out of this set your AC fan to "ON" instead of AUTO that way the oils are constantly getting pushed by the ac so you aren't wasting any fragrance. I got the white color although I don't see it because it's in my attic i do love the casing colors as well as the black. If u have candle or air freshener in ur house go ahead and trash them and get this today! Also one bottle of oil has lasted me 2 1/2 months so far. Already paying itself off in the money I've spent on candles and stuff. ... show more

Review Image by Matt’s Reviews & Recommendations
I’ve been using this smart scent machine in my home, and overall it works very well. One of the first things I noticed is that people immediately comment on how good the house smells when they walk in. The scent coverage is strong and consistent without being overwhelming. The automatic function is a big plus. Once it’s set up, it’s pretty much set it and forget it. It runs on a schedule without needing constant adjustments, which makes it easy to live with day to day. Installation was also fairly simple and didn’t take much time. The app does its job, but it feels a bit unrefined, and the connection to the device can be temperamental at times. That said, this isn’t a huge deal because once you’ve set your schedule and scent strength, you rarely need to open the app again. There is one thing worth keeping in mind, especially if you live somewhere with cold seasons. This is unverified, but based on my experience: if you run the diffuser regularly while not using your AC and then switch over to heat in the winter, you may notice some “smoke” the first time the furnace kicks on. When I turned on my heat for the first time this season, my home filled with a noticeable amount of diffuser-oil-scented smoke. My assumption is that the oil either coated the ductwork over time or possibly made its way into the furnace, and then burned off when the heat was first used. After that initial occurrence, things returned to normal, but it’s definitely something to be aware of if you plan to leave the diffuser running year-round without HVAC airflow. Pros: • Works very well and distributes scent evenly • Guests notice and compliment the scent when entering the home • Automatic mode makes it mostly set and forget • Easy installation • Large capacity, doesn’t need constant refilling Cons: • App feels a bit unpolished • Device connection can be temperamental • Potential oil buildup in ductwork or HVAC system (unverified) • Possible scented smoke when turning on heat for the first time in winter Overall, this is a great scent machine that does exactly what it’s supposed to do and makes the house smell great. Just be mindful of how and when you’re running it if it’s connected to or near your HVAC system, especially during seasonal changes. ... show more

    • Quiet luxury — Worth all 5 stars
Color: White Set name: U5
**I was not bribed to leave a review nor do I get anything in return for providing one. I straight up just love this machine** If you’re on the fence about buying this, do yourself a favor and make the purchase. You only get to make a first impression once and it’s truly shocking how many guests have commented on my house’s pleasant scent as soon as they walk in. It’s the same sensation as walking into a luxury hotel, which is exactly the vibe I was going for. The unit itself feels quality as the exterior panels are made of glass. No issues with loose fixtures, leaks, etc. Anyone who left a bad review claiming that the machine is “loud” is being dramatic. It’s not at all. Hooking the unit up to my HVAC was a breeze, especially because all of the conversion pieces are included in the kit. It took less than 5 minutes. Like others have said, the app could use some updating but it’s overall very easy to operate. I inquired with customer service about making an adjustment so the scent gets dispersed only when the HVAC fan kicks on — Bella was quick to respond with a video showing the setup process and even threw in a free bottle of oil to try out when I told her I was on the fence about choosing a scent. Genuinely good customer service is hard to come by these days (especially because they don’t ask for tips like every other place now) and this company’s efforts are worth noting. Thank you for actually caring. Once you have your strength settings set to your liking there isn’t much looking back. For reference, I have a 3,500 square foot house. I set my unit to disperse for 15 seconds with 300 second pauses in between. It runs daily from 9am-11pm. A 500ml bottle of oil lasts me around 4 months. I’ve had it since June 2025 and there is no residual buildup in my vent system, which was something I was worried about. I wasted so much money on candles in the past it’s not even funny. I wish I would’ve purchased it sooner. Realistically, I think Aromadd should charge more for this product because of what you’re getting in return, but I admire that they’re not in it for the money. If you look at the price history tracker you’ll see that the cost hasn’t budged at all over the course of several months, holidays included. That’s honorable. This product is great. This company is great. I convinced my nail salon to buy one (lol). You should buy one too. ... show more
