2025 Upgraded 3500 Sq.Ft Smart Scent Machine - HVAC System, Whole House Aroma & Hotel Collection Diffuser, Waterless Essential Oil Diffuser for Home, Office, 600ML Capacity, Cold Air Tech (Black)

The product is good. My customer service experience has been outstanding. I attached this diffuser to my main air handler in my house. It worked alright, but I needed to route the lines a little better. I did that, but they wouldn't stay out. So, I needed to get more of the clear rubber tubing. I bought this item and needed replacement pieces 5 months later and they sent them with no issues and with no charge. If I ever need to get another diffuser, I'll go with this company. Hands down, easy and no hassle customer service. This diffuser uses an app for control. The app is good; it gets the job done. You can adjust rest times, time for expelling the oil and what days it works on. You can also select different schedules. The basics of customization are covered. The clear tubing has a slightly larger OD diameter than what is commercially available. We're talking .001 of an inch. It makes a difference because the oil will leak from between the tubing and the fitting on the diffuser if it isn't the right size. I have about an 1800 square foot house and this diffuser fills the house. It's not overpowering or even close. It's a good fit. If you don't get this diffuser from them, by a different one, but go with this company. Their customer service makes everything much easier to deal with.

I am beyond impressed with the 2025 Upgraded 3500 Sq.Ft Smart Scent Machine. From the moment I set it up, my entire home smells like a luxury hotel. The HVAC integration works flawlessly and distributes the scent evenly throughout the whole house—no overpowering spots, just a clean, consistent aroma everywhere. The 600ML capacity is a huge plus and lasts a long time, making it very low-maintenance. I also love that it’s waterless and uses cold air diffusion technology, which keeps the essential oils pure and long-lasting without any residue or moisture issues. Setup was simple, the machine is whisper-quiet, and the sleek white design blends perfectly into my home. It truly transforms the atmosphere—guests constantly ask what scent I’m using because it smells so high-end and professional. If you’re looking for a whole-home scenting solution that delivers real hotel-quality results for your house or office, this is absolutely worth it. Highly recommend!

Amazing!!! I have 4 large inside dogs that love to run around our yard, roll in the grass and swim in our pool. I always feel like my house smells like wet dog, no matter how much I bathe them. We connected this to our a/c duct in the attic. It was so easy and took under 5 minutes to do. We could immediately smell the scent throughout the house. I love that it's Bluetooth and I can work it from my phone and set schedules.

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.

Works perfectly and my entire house smells great
