Very honest product. I applied it to a Nissan Almera N16, on the evaporator, removed the hose underneath, and it came out with pitch-black liquid. It also released black liquid from the hose that drips water from the air conditioner's heat exchanger under the car. I will get more sprays to spray directly into the hose located under the car, as that is where the cause of the damp smell is.
I do not recommend it for the air vents. It can drip onto the radio and other electrical components and cause a short circuit.

cleans the air ducts from mold and bad odor. I apply it once a year and the system never smells.

It is a decent substitute for professional air conditioning disinfection. The spray automatically sprays for about five minutes and the whole process takes about half an hour to preheat the car and then ventilate it. I can say that it definitely reduced the unpleasant smell of the air conditioning, but I'm not sure it eliminated it. I will return in a few months when the heat starts.

I followed exactly the instructions written on the bottle and after completing the tasks, the air from the air conditioner came out clean and fresh again, without any odor.

Very effective, it eliminated odors, I needed to use almost all of it in one use so prefer disinfectants with 520ml to be sure you won't need another bottle.

I bought this particular product because it seemed easy and simple in the videos on the internet. After following the instructions in the videos, the result left me with a very unpleasant smell of polyurethane. I had to take it for cleaning, where they suggested other solutions.

The product does what it promises as long as you use it correctly. It has an active ingredient against fungi and not just a fragrance.
I have been using it for years in my cars and half the amount is enough for each vehicle.
I also had a problem with strong odors, but after the first use, they decreased by 90% and they never smelled again from the second time.
You need to put it in the air vents, but the most important thing is to remove the cabin filter and clean the area before applying the foam on the evaporator with an effort to penetrate it, because that is always the problem with odors inside the evaporator due to the presence of fungi.
I recommend using it once a year.

By far the best product I have tried.

Even without applying the instructions 100%, it eliminated strong and unpleasant odors with just 2 uses (1 bottle over a week).

I sprayed it on the cabin filter, inserting the tube, as well as inside the air vents, without excessive amounts. The first use eliminated 70% of the odors, especially when I turned on the air conditioning. The second time, it completely got rid of the coffee smell

For the best result, use a larger amount of foam than the one mentioned in the packaging instructions.

I used it on a 2013 Yaris. It’s good, it has instructions, so don’t rely exclusively on comments and videos. Personally, I sprayed carefully toward the fan while the air conditioning was running, having obviously removed the cabin filter and. Under the drain, after about 15 minutes, all the liquid will end up there, which is supposedly supposed to have cleaned the whole system. Don’t use too much, 1/3 of the bottle is enough. Avoid the air vents; those who put it in the air vents don’t know what they’re doing. It makes no sense to put it there, not to mention that white spots may remain inside them.

The car had a strange smell when I put on recycling. The situation improved, but I think that a better job could be done!

The product is very good and powerful. For this reason, it is better to wear a mask during use. The problem is all the conflicting instructions on how to do it. A video on YouTube that some people mention here is quite different from the instructions on the container (when the filter comes out, air distribution position, etc.). Also, the container says to spray inside the ventilation openings because someone else says it is wrong. In any case, you will use the heat to dry and disperse the foam of the container

I tried a more famous product first, which had half the quantity and caused me a problem. It didn't even reach enough to spray the vents. With this product, I found my health. Sufficient quantity and quite aromatic, at half the price. I will definitely buy it again.

The correct use of the cleaner is as shown in the video below and not to spray it inside the air vent. It is WRONG.

It is very good! Nice scent, good quantity, and it does a good job cleaning! I highly recommend it! The car from the previous owner had an odor problem in the system and I managed to eliminate it by combining it with drying the air conditioner 5 minutes before parking.
