In addition to being functional, current models are easy to install and integrate well with the decor, making them ideal for those who want to keep the house ventilated and, at the same time, protected against insects.

Plants such as basil, mint, lavender, and citronella are known for their natural repellent properties and still add charm to the decor of projects. Placed near windows, doors, or food-preparation areas, they help create an aromatic barrier that subtly keeps flies away, while contributing to a greener, fresher, and more welcoming space.
