I don't know if it's ULV, however it is a cold fogger. I use MGK SECTOR misting concentrate. The product comes with a list of what it kills and the ratio of product to water specific to what you need it for.

Awesome product and easy to use!!!
[This review was collected as part of a promotion.] I use one of these to disinfect an office space during the covid-19 pandemic. It operates very well and it's easy to use, works a long time on one charge. I like you able to use various liquids and chemicals for each situation.

Ridiculously Poor Battery Life!!
The very first time I used this fogger, after fully charging the battery, only a tiny portion of the tank was emptied. I didn't time it but it didn't last long. I would be satisfied with one tank dispersed per charge but not waiting for the battery to cool down and re-charge multiple times for each tank of fluid. Now I understand the low price. No more Ryobi for me and this will be returned.

Wonderful work horse of a machine
[This review was collected as part of a promotion.] I brought this about Four month ago. I had a Ortho sprayer also. The Ryobi prove to be tremendously more reliable machine. It was amazing how it held up with no defects. I have recommended this produce to many, many people and all but one has purchased it and are very please.

Does exactly what it was built for and more
[This review was collected as part of a promotion.] I purchased this because a classroom setting needed cleaning that is let's be honest it is not cleaned by a hand held sprayers and paper towels by people who become less than thrilled to do it. This made it fun and better placement of solution to get the job done effectively. Easy to use, easy to clean good battery usage

This is my 2nd Ryobi Fogger/Mister, I returned the 1st one thinking maybe it was defective, the 2nd one does the same. It sprays very weak, works well with water only, but can't handle any type of mixture. With a mixture of chemical of any kind, it goes from extremely lite mist to none and it sputters. I think the little filter on the intake hose isn't letting much in, and I can't modify it because the tank doesn't separate from the machine. I will be returning this one too. This could be a great product, but Ryobi needs to tweak some of the defects first.

Hello, Ladypco - We are sorry that you're not having a good experience with your ONE+ Fogger! If you would, please make sure the chemicals you're using are as thin as water. Thicker liquids will not spray properly. If the chemicals are as thin as water, then please email us at reviews@ryobitools.com. We want to hear more, so we can try and turn this experience around!

Totally amazed
I can see why this product is out of stock everywhere. It really works. No more wasting money on aerosol cans of backyard fogger. No more spraying my skin with DEET products. I think you can use just about any repellent with this machine as long as you dilute it so that the fluid has the same viscosity as water. Refer to instructions for details. Highly recommend! Best to purchase I’ve made in a while and just in time for a break out of west nile virus here inFlorida
