Passive Air Inlet Vents with Filter – For Window Frame Installation
These filtered passive air inlet vents are designed to be installed directly into the window frame, allowing a controlled flow of fresh outdoor air into the room without drafts.

They are ideal for homes with passive ventilation systems, especially in older buildings where air circulation depends on natural pressure differences. The integrated filter improves indoor air quality by capturing pollen, dust, and other airborne particles, making them suitable for allergy-sensitive users.
