Customer Reviews for VEVOR Upgrade HVAC Scent Diffuser for Whole House, 850ML Scent Air Machine with Cold Air Technology, Waterless Essential Oil Diffuser, Cover Up to 5000 Sq.Ft for Large Room, Hotel, Spa, Office

I don't really like this unit. It's easily tips over and spills. (I use it on my kitchen counter) Big portion of the mist falls back on the counter. I assuming it can't make fine enough mist. However it works from battery and 5V dc USB c power. If you planning to buy buy the 180 ml unit. It's a little bit more expensive but way better quality.

The unit works very well. Easy setup. The bottle locking mechanism was weird for the first time. I use it on the lowest setting in a 24'x30' room (5 sec on 300 sec off) . According to the app it will last almost a year without refill.

Bigger than I thought. But still exactly what I need to keep my rentals and airbnb always smelling minty (great rodent deterrent). Simple design. But the menu could be a little more comprehensive. The app sucks. But again this is just a fancy airwick canister. Over priced hype on all these essential oil atomizers at the end of the day. But hey atleast vevor was cheaper than the rest.

Excellent high outlet diffuser. With covers my entire first floor, 1600 s.f. with aroma. I like that u can control the intensity of the aroma and frequency of usage.i had two other manufacturer's cold air diffuser, they didn't have the aroma output like this one. The secret is buying good high quality essential oil. Highly recommended.

Purchased this small one to sit in a small room. Works great and is Bluetooth controlled. Put out just enough fragrance that can be controlled by your phone.

this product totally sucks he designed so the top has to be taken off every time you fill it, which makes no sense at all. You could’ve cut a slot and it could’ve been pulled right out like other people do well not buy anymore till you fix this issue.

Absolutely love this scent machine. I had paid over 300.00 for the first one I bought. And this one is better than the expensive one. It's easy to program. Absolutely love it. Gonna order another soon

Easy to use, definitely met my expectations.

This is a very good it works well

This is great—no dilution or frequent refills and not messy at all! The app is very, very basic but it works so it’s fine.
