4.5L Electric ULV Fogger Machine Sprayer,Portable Atomizer Foggers Mist Cold with Adjustable Flow Rate for Home Indoor

Easy to handle and sprays a nice fine mist

This product works very well. It’s as easy as filling up the tank and turning it on. It fogs about 25 feet forward and about 3 feet wide in its range. I can fog a medium size church in about five minutes. This product works as the seller has described.

The media could not be loaded.  Seemed like a decent product but the power switch would not move to the 'on' position on the one I received. I am having it replaced in-kind and will try to remember to update this review.On receipt of the replacement, I noticed the plastic over the switch was torn through so I tried the switch right away and found this one stuck in the ON position. In looking around, I could see the likely reason. The switch is at the uppermost part of the sprayer and there is no packing to protect it from ramming into the inside top of the box. Damage to the inside of the box can be seen in the picture attached. This explains also the hole in the plastic at the switch location, it was from abrasion.

I bought this to use with a disinfectant (Decon 30 - also available on Amazon) as a pre-cleaning/knock-down treatment for possible mold spores. I would not recommend it for this purpose. The unit is pretty powerful and whatever liquid you use shoots out with considerable force - it's like using a leaf blower that shoots out a mist. It has enough force to blow paper and other light-weight items off tables, desks, etc. The last thing you want to do with mold spores is blow them around. My expectation of this machine was that it would mist the room, and the mist would take down any airborne spores and deactivate them. Instead, I feel like this just stirred everything up. Which is just the opposite of what you want to do. Another problem is that I was using this in average rooms in a house. This machine's spray range is 26-34ft., a lot longer than any average room in a house. It was sort of like using a fire hose to water your lawn. Before I used this in the house, I wish I had filled the tank with water and tested using it outside or in the garage first. It would have helped a lot.Although it didn't work for my purpose, I think it's a good sprayer.It comes fully assembled. The directions aren't too helpful, and seem to have been written by someone whose first language is not English. When I first opened the box, I saw what looked like a mystery bag of parts. But I figured out the parts area a replacement on/off switch, a spare tank cap, and a mystery disk that looks like maybe it's a filter. There is no explanation of these parts or how to use them in the manual. The manual makes reference to different parts on the unit, but unfortunately there's no diagram showing where the parts are on the unit.You really don't need the directions, as all I had to do was add the disinfectant (or "potion" as the directions say), and turn it on. I must have added 1/2 a gallon of cleaner to the tank and only used a fraction of that. It does spray a very fine mist; I saw no evidence of the cleaner on any surfaces, even on mirrors. (I had watched several YouTube videos beforehand on how to spray.)It comes with a 16ft cord, but I recommend using a heavy-duty 25 foot or longer extension cord (as I did) so you can go to one location after another without having to stop, unplug the unit, and then plug it in again. This is especially important because I definitely recommend staying out of any areas you spray for at least 30 minutes.Before using this I had watched several YouTube videos of people using this unit or similar units. I noticed that they would spray as as they were walking into a room and walked directly into the area they just treated. I really don't recommend this. I recommend walking backward and out of the room as you spray, so you're not walking into any areas you just treated.I walked backward and out of the rooms as I was spraying and even so I felt a little eye and lung irritation from the disinfectant I was using. Which brings me to my next point.I would definitely wear eye protection (goggles) and a good quality mask (N95 or even a respirator) when using this. I was wearing eye glasses and a KN95 mask and still had some eye and lung irritation. This unit does spray very fine particles. You might also want to wear long-sleeves and head/hair protection.So to sum up, this is a good piece of equipment for large open areas. Spraying goes extremely fast, and it doesn't seem to require a lot of liquid. I would use it to disinfect smaller areas (like the rooms in a house), keeping in mind it might blow off papers and other light-weight items from tables, desks, etc.; but if you want to spray something for clean-up or remediation in a house, the force of this is too high and will stir up whatever it is you're trying to clean up or remediate. Before you start devise a strategy for the flow of how you're going walk through the areas to spray; start with the inner most rooms/areas, and finish close to a door, so that you can turn off the machine and leave the area immediately until the mist settles. At a minimum wear goggles and a good mask; adding long sleeves and hair/head protection is even better. Before using the sprayer with disinfectant or cleaner, you may want to fill the tank with water and test using it.

I bought two of these, one for my Ski Patrollers to us in aid station, the other for our ambulance service to use in our trucks and base. Everyone loves them, for ease of use and the short time needed to clean, you fog things down and let it dry and you are good to go.

Sprays out too much, too fast, too large of drops. Quickly over saturates. With much practice and planning I get it to work almost okay. An atomizer, or even a really fine misting, would get the chemicals in cracks and crevacies but this doesn't; and I need that.

Did not use but know it is good

Powerful air flow sends a more than expected mist blowing the active ingredient all over the intended target area, yes.

Being in the remediation business this fogger is amazing

Delai rapide et bonne machine
