I performed the cleaning process (in the air ducts and in the cabin filter area). The tube was good, it reached quite far into the ducts. The result is good, the musty smell I had when I turned on the air conditioning is no longer there. I can't say that there is any fragrance from the product but that wasn't the goal. The only thing I didn't like is that there were several instances where the product was in liquid form (i.e. foam and liquid). As for the quantity, I did one cleaning and I think it will be enough for one more.

Excellent for its price. It removed the odors from the system but leaves some residue in the air ducts that need cleaning.

After using it, there is a feeling of freshness for a few days... afterwards, it's indifferent but at least it doesn't smell bad. Over time, its effectiveness will show... I will return

For 4-5 days it's good, although I used it after a complete cleaning of the vehicle's air conditioning and a new cabin filter. Nice scent but it doesn't last, and of course, you can't measure if it works on the germs.

3.7 stars from me.

The air conditioning hadn't been cleaned in a while (the car I bought was used). The foam did the job, it cleaned, but it could have done better. I felt that there was still some smell even after using it. And after 1-2 months of use, I still notice a slight smell at the beginning, that is, when opening the a/c.

It really does its job, it is easy to use. It is exactly what you need now in the summer when the car air conditioner is working overtime.
It is truly antibacterial, it eliminates unpleasant odors and leaves a nice scent that lasts for a few days.
After the scent weakens and fades away, it smells like clean, cool air.
P.S: Let's also change the cabin filter, guys, right? And if it's not time yet, at least we can take it out and let it go in the air.

It left a pleasant fresh scent for 2-3 days and then it's gone. However, after use, that annoying smell has stopped when you put on the air conditioner and the air comes as if it has mold inside! Very good for its money

I bought this specific product, installed it in the air vents, and it caused problems with the radio. The manufacturing company and the representative in Greece should have known and informed about this. So, stay away! I spent 50€ to fix it and it burned circuit boards

It does what it promises..
Cleans odors and dangerous microorganisms from the entire circuit. Leaves a light lemon scent (although not mentioned).
Be careful with the nozzle when entering narrow vents. It may get stuck and remain in the air ducts upon exit.
Sufficient for 2 vehicles or uses.
(remove the cabin filter and then place it back or use a new one)
Recommended!

It's worth its money and it's enough to use it in 2 cars, if it's just for maintenance and not for a car that has never cleaned its A/C and air vents. It leaves a very light scent that is not bothersome.

Easy to use. Large quantity. I filled all the air vents, both on the top and on the legs, and there was some left over.

I really didn't expect it. The result is excellent. You remove the filter and pour the foam inside. You close the filter's lid. Then you pour it into all the air vents, moving from the back of the vent towards the outside. You leave it for 15 minutes to take effect. Then you open the air conditioner at the lowest temperature and the lowest fan speed, gradually increasing the speed while wiping away the foam that comes out. You place the filter back or replace it with a new one. Perfect result!

It is the first product I have tried for car air conditioning and I was completely satisfied. I bought a second one for my wife's car.

Very good product, does what it claims. The air conditioning in my car suddenly started smelling very strong for about a week, until I used this product.
With a little straightening of the attachment/hose, it can penetrate deeper into each air vent. Personally, I removed the cabin filter as the instructions say and put the foam there as well.
Since there was leftover foam, I put it back in the front air vents and noticed that the foam that overflowed (from the first release) was somewhat brown, obviously from dust, dirt, etc.
The strong odor stopped immediately. I also proceeded to change the cabin filter.

It does what it says and mainly disinfects and eliminates unpleasant odors from air vents caused by bacteria. In the first few days, it has a pleasant smell and then the odor is eliminated and the air becomes odorless. Be careful because it will definitely leave liquid behind the dashboard from leaks, so it may cause a short circuit in bare wire contacts. I recommend, in the end, after emptying the entire bottle and the foam is liquefied, to blow air everywhere while the heater is working
