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 (White)

I've been on the fence about buying a diffuser. Not many reviews about how long the oil will last. Well, I got tired of every 2 months buying 13 Wallflower refills from Bath & Body Works. After some research, I decided to give this one a chance. We have 1 level, 5 bedrooms and 3 bathrooms, 2160sqft. This thing is great. We get the fragrance in mostly all parts of the house. We have 2 bedrooms closed off due to non-usage. I have it in a central location in the house, and I set the unit to it's longest time interval which is 900 secs or 15 mins. We allow it to pump out the fragrance for 15 secs. So 4 times an hour with a total of 60 secs. We bought a 16oz bottle of a hotel collection fragrance. This unit will hold 500ml of oil. 16oz is roughly 475ml rounded up. We have been running this thing 4 times an hour for 15secs per run, and it hasn't hardly used much oil. Very different from the reviews I've seen on so many other sites. It seems that most complain about the oil running out pretty fast. We wanted to see how long it would last before converting this to the HVAC system for a true whole house experience. I took a photo of the oil bottle and how much has been used over the last month. I wanted to give it a month to see how much it used. Didn't use much as you can see in the photo. It hasn't even reached the 450ml mark and remember it was about 475ml when I filled it with the 16oz bottle. Well, worth the purchase. We will be trying a few more fragrances to see which we settle on.

I rarely leave reviews, but this product and the Aromadd team absolutely earned it.The U5 SMART HVAC Essential Oil Diffuser blew away my expectations. It’s powerful, quiet, and seamlessly connects to my HVAC system without hassle. The scent distribution is even and consistent, filling my entire home with the exact vibe I want—whether it’s fresh and clean or cozy and relaxing. What sets the U5 apart from other diffusers I’ve tried is how hands-off it is once set up. No mess, no spills, no daily maintenance.But honestly, the real star of the show is Aromadd’s customer service. I had a few accessory-related questions and was blown away by the response. Cindy from their after-sales team followed up promptly and kindly, went above and beyond, and made me feel like I was their #1 customer. She didn’t just answer my questions—she made sure I was taken care of.In a world where customer service is usually an afterthought, Aromadd’s team treats you like family. That alone is reason to buy from them.If you’re on the fence: don’t be. Buy it. You’ll be glad you did.

I bought this to use at my office, and I love it so far. I haven't set up the app yet, but I plan to so that I can set up a schedule for it. I love how quietly it runs and how much scent it puts out. I am thinking of purchasing another one for my home. It is perfect! I love the sleek design.I would also like to mention how wonderful Aromadd's customer service is. This makes all the difference. I had the pleasure of having Bella help me with a concern. I thought I was missing a part, and I reached out to customer service to request it. Bella's response time and attention to details was the best experience ever. Bella verified the part I was concerned about was actually upgraded and looked different. She sent me a picture of what the part should look like, and it turned out, there were no missing parts. My concerns were addressed and resolved withing 24 hours. I highly recommend buying from Aromadd for a quality product and for their amazing customer support team. They are wonderful!

We bought this as a Christmas gift along with 5oz of the “Dubai” scent to try it out. With 7 people in the house (and a dog) we were cooking meals throughout the holidays, so it was not as noticeable in our 2,500sqft, one-level, home at first. But over time it grew more aromatic. Now that everyone has left, and we come home from work, there’s a nice, pleasant, not-perfumy, scent in the house. The 5oz bottle I put in the reservoir is still being used 12 days later. The reservoir holds 20oz I think, so it is reasonable to assume a full reservoir would last a month or two depending on the settings. Maybe 3 mo on the lowest settings.We gave it set to run for 10 seconds every 10 min which is more than enough. I may back it down some more, we’ll see. My only beef with it is the settings are in seconds and the max interval is 900 seconds. If you want less scent, you have to then decrease the mist time. It’s not the best app in the world, but it works. The front panel controls are frustrating (like setting a 1980’s VCR), but the app makes it tolerable.As far as coverage, I can smell it in every room that has an open door, which is great. We put it in a central location and the ceiling fan I think helps it circulate.The unit itself is about the size of a shoe box. So it fits anywhere we want. There is also a hose attachment and instructions for how to feed it into your HVAC system. I may try that once we settle on a scene like. Seems more efficient than just the box shooting out mist.The Dubai scent is nice, and smells nondescript like a generic dryer sheet maybe. Not floral or citrus or perfume. Light and fresh. We’re going to try a pine essential oil once the Dubai runs out.

We have a 10,000 sq ft gymnastics gym in Florida. With the increase in seasonal humidity, the typical gym smells of cheesy feet and B.O. tend to be the welcoming scent when you enter. Yuck! I just installed my Aromadd 2025 3,500 sq ft diffuser, and I can't believe the difference it made! No more stinky funk when you enter. Everyone mentioned how it smelled so fresh and clean. This device is SO worth the price! I was shocked that it scented all 10,000 sq ft. We're buying a 2nd unit for our house.The app is simple to use and allows you to dial-in your scent level exactly. Once everything is set, just forget about it and let the machine do its thing. Installation is easy and programming is a breeze.
