Hello, first of all, we send our best wishes to your son. We wish healing. The Çankırı gray natural salt lamp you have reviewed, weighing 1-2 KG, is a very sufficient and ideal size for children's rooms, which are narrow and not very large in square meters, as you mentioned. Regarding allergies; genuine Çankırı rock salt lamps emit negative (-) ions into the environment as the bulb inside heats up. These negative ions help to clean the room's air by causing airborne dust, pollen, and allergens to fall to the ground. It will contribute to alleviating allergic reactions such as sneezing and throat irritation that your son experiences in the mornings, as it improves the quality of the air and refreshes it. For best effect we recommend leaving it on in the room overnight. We wish you healthy days and comfortable nights. Best regards
