Filter mounts right to duct fan but slightly loose, sealed with foil tape and a clamp for safety and is now snug/air tight. Placed the exhaust tube directly into a 4” duct boot/vent filled with dryer sheets for extra clean scent. Easy assembly. Worth the money. ### ⭐⭐⭐⭐⭐ Begeistert✨️ *by on Reviewed in Germany 14 September 2026* Ein sehr zuverlässiges Gerät was hält was es verspricht...die Wartezeit wurde um einen Tag unterboten und der Aufbau ist quasi selbsterklärend.Im großen und ganzen ein sehr gutes/zuverlässiges Gerät zu einem angebrachten Preis...nur zu empfehlen!☝🏻😌 ### ⭐⭐⭐⭐⭐ Funcionamiento perfecto 👌💯 *by on Reviewed in Spain 1 July 2026* El producto es perfecto, espero que dure mucho , trabaja perfectamente y el filtro cumple su función.Mis margaritas ahora tienen un control de el clima casi ideal , recomendado calidad precio.
