2. Follow official instructions for HVAC connections; DIY damage is not covered.
3. Clean regularly to prevent clogs and leaks.
Can the diffuser damage my furniture or cause oil leaks?
Protect your furniture and prevent leaks with simple care. Regularly clean your AROMADD to avoid nozzle buildup, and for peace of mind, place it on a waterproof tray.

Good product, amazing customer service.
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.

BEST INVESTMENT! LOVE THIS DIFFUSER
This is by far the best investment I have made to make my home smell good all the time. I’ve tried everything from plug ins, candles, wax melts sprays you name and it would last 1 week if that and then nose blind or it just wouldn’t be as powerful. I had purchased another diffuser not this brand, but sent it back because it was loud and didn’t work if my phone was not nearby. I decided to pay alittle more and try this one. AMAZING! first off it connects to my wifi and I control it through the app from anywhere. Very easy to setup for me. It took me awhile to adjust it to the perfect setting though but that’s normal I didn’t want the scent over powering nor too little so you have to play with it for awhile. It is a quiet machine compared to the one I had tried out, I can visibly see the mist and it fills my home with greatness. My house is a 2600sqft and it reaches to my second floor without connecting it to the HVAC. I notice the scent even comes into my office upstairs with the door closed. Im truly impressed and I hope it lasts me for a long time. I purchased a 4oz scent to try and see what scent I want for my house and let me tell you, it’s been over a month already and there is still scent in the bottle to last me awhile. I can only imagine how long it would last if I filled up the diffuser bottle to the top. I understand some people have had issues with theirs but I have not and am greatful. Thank you Aromad for finally making this product and I can throw everything else away! I only need this in my home.

Awesome product and customer service.
Makes home smell great, the app works great and easy to use, will buy one for our cabin as well. Bella was fast and responsive with the questions I had and went above and beyond sending us an extra bottle to have to swap out scents. Top notch all the way around . Highly recommend!

If you’re on the fence read this review!
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 refillingCons:• 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 winterOverall, 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.
