Is the noise level of the Aromadd waterless essential oil diffuser loud during operation?
We conducted noise sampling on diffusers in the market, revealing that 89.5% of them have noise issues. Since our diffuser uses dual-fluid technology (which atomizes liquid with high-pressure gas), it may produce slight noise during operation.

If I were to rate the Aromadd, I’d give it an 8 out of 10. While it does produce slight noise, it’s acceptable for me. With a coverage of 3,500 sq.ft, I usually place it outside the bedroom, and the fragrance still comfortably fills the room.

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; itâs 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. Iâm 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.

Well Worth the Purchase
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.

Best HVAC Diffuser on the Market + Customer Service That Deserves a Medal
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. Itâs 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 wantâwhether itâs fresh and clean or cozy and relaxing. What sets the U5 apart from other diffusers Iâve 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 Aromaddâs 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 didnât just answer my questionsâshe made sure I was taken care of.In a world where customer service is usually an afterthought, Aromaddâs team treats you like family. That alone is reason to buy from them.If youâre on the fence: donât be. Buy it. Youâll be glad you did.

Quiet and effective
We bought this as a Christmas gift along with 5oz of the âDubaiâ 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, thereâs 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, weâll 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. Itâs not the best app in the world, but it works. The front panel controls are frustrating (like setting a 1980âs 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. Weâre going to try a pine essential oil once the Dubai runs out.
