I am satisfied with this product 100% and recommend it to anyone who is suffering from house dust allergy, only highly recommend. At first I was skeptical about whether me to spray with my complaints (watery eyes, runny nose, cough) can really help, as I have already, without much success, tried with various medications. But I can assure everyone that it to me after the first application already at least 80% better off (no more watery eyes, only now and then I have to clean and the cough has also greatly reduced the nose). I once all things (bed, mattress, bed, pillows, carpets) completely sprayed 30 minutes soak, vacuumed and sprayed again. The next day, my complaints were immediately better (see above). I'll take my stuff now regularly spray and am glad that I bought immediately 2.5 l.
