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. Review: Solid performance for the price, and amazing customer service - 10/28/25 update: I’ve had the diffuser for about four months now, and it still works great. The scent level is consistent, and I like how it passively fills my entire home when I turn it on with the HVAC fan. After my original review, the company reached out to understand my feedback, which showed how much they care about their customers. Their customer service was excellent, they listened, offered helpful information, and even sent sample scents as a thank you. I originally mentioned some noise and Wi-Fi connection issues. It does connect to Wi-Fi, but the company recommends using Bluetooth for now while they improve the app. As for the noise, it’s not really a product issue. I moved it to my HVAC closet and can’t hear it anymore. Overall, this is a solid product backed by outstanding customer service. I definitely recommend it. Original: I’ve been using this diffuser for about a month, and for the cost, it does an impressive job. I started with a smaller unit in my living room but wanted something powerful enough to cover my entire first floor (about 1,100 sq. ft.). This diffuser definitely delivers on that front, it fills the whole space with scent. That said, it’s not quiet. The sound carries across the house, so I wouldn’t recommend it for a bedroom if you’re a light sleeper. I ended up connecting mine to my HVAC system, which not only solved the noise issue but also helps distribute the scent evenly throughout the house. Installation into the HVAC was fairly seamless, though you do need to make sure your system’s fan is running; otherwise, the diffuser just pumps fragrance into the ducts until the air kicks on. Where this product falls short is the app. A couple of things stood out: It only runs on Bluetooth, not WiFi, which means you can’t control it when you’re away from home. The scheduling feature works, but it’s not very intuitive. Setting up different times for different days is unnecessarily complicated. I wish there were a simple “quick set” option to run the diffuser for a set number of hours at a chosen level (e.g., 4 hours on level 8). My previous diffuser had this feature, and it was a lot more user-friendly. Overall, this is a solid diffuser for the price. It’s powerful enough to fill large spaces, works well with an HVAC system, and does exactly what it’s supposed to. But between the noise level and the frustrating app experience, it loses a couple of stars ## Features - AROMADD 2025 NEWLY UPGRADED: The Aromadd waterless essential oil diffuser utilizes the latest cold air diffusion technology, combining cold filtered air and high-pressure air to fully atomize the essential oil into fine particles for efficient diffusion.

If using another brand, ensure it's compatible with waterless diffusers. **Q: Does the diffuser require regular cleaning?** A: Yes. Clean the diffuser monthly, or more often with frequent use.
