Luckily there was a similar model already installed before so I didn't have to drill a massive hole. I think these passive air vents are a straightforward and effective solution for improving indoor air quality without the noise or running costs of a mechanical system. The 4-inch diameter seems standard size and fit the existing hole in the wall perfectly. It is ideal for providing a consistent stream of fresh air into the bathroom (or any other room as required), helping to prevent the build-up of condensation. The construction of this unit feels durable, especially the external grill made from stainless steel, which can't break as easily as the plastic versions available. I found the replacement process quite simple due to the extendable ducting, which allows the unit to pass through various wall thicknesses without needing complex modifications or additional piping. The airflow can be adjusted, so you can manually control the volume of intake depending on the season, which is essential for preventing drafts during the colder months. I have also noticed that the included filter does a good job of trapping dust so it doesn't enter the bathroom. The bathroom faces a fairly busy road outside and there would otherwise be a lot of black micro dust inside the room. Since there is no motor, the vent operates in complete silence, doesn't generate further costs for electricity and should last much longer than an electric fan. ## Features - Natural Through Wall Ventilation - Provides continuous passive ventilation without electricity or a motor, using natural air pressure differences to support steady air exchange between indoor and outdoor environments - Energy-Efficient Passive Airflow Design - No power supply required and no running costs, offering a simple and efficient way to improve home ventilation without increasing energy consumption - 3-Level Adjustable Airflow Control - Features an internal ABS cover with 3 airflow settings, allowing you to adjust ventilation levels according to room conditions and seasonal needs for balanced indoor airflow - Flexible Installation with 100mm Telescopic Duct - Includes a 4 inch (100mm) aluminium telescopic duct that adjusts to different wall thicknesses, making it suitable for various wall structures and easy through-wall installation - Durable SS304 External Grille with Mesh Protection - Equipped with a weather-resistant stainless steel 304 external cover with 45° rain-deflecting design and integrated mesh filter to help block insects and debris while ensuring stable airflow - Easy Maintenance and Removable Filter - Designed for simple maintenance with a removable internal filter for easy cleaning and replacement, helping maintain consistent ventilation performance over time ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0FJ1GLRDF | | Air Flow Capacity | 130 Cubic Inches Per Minute | | Best Sellers Rank | 263,186 in DIY & Tools ( See Top 100 in DIY & Tools ) 150 in Household Ventilation Fans | | Brand | Weiworld | | Brand Name | Weiworld | | Colour | White | | Country of Origin | China | | Customer Reviews | 4.6 out of 5 stars 11 Reviews | | Electric Fan Design | Exhaust Fan | | Electric fan design | Exhaust Fan | | Installation Type | Through Wall | | Item Dimensions D x W x H | 15D x 16W x 20H centimetres | | Item Weight | 0.5 Kilograms | | Manufacturer | shenzhenshi zhongguan nengyuan keji youxian gongsi | | Material | Acrylonitrile Butadiene Styrene, Stainless Steel | | Model Number | FAV-100 | | Mounting Type | Wall Mount | | Noise Level | 18 Decibels | | Number of Power Levels | 3 | | Number of Speeds | 3 | | Power Source | Air Powered | | Power source | Air Powered | | Product Warranty | 1 year manufacturer. | | Product dimensions | 15D x 16W x 20H centimetres | | Recommended Uses For Product | Ventilating | | Room Type | Attic, Bedroom, Home Office | | Size | 100 mm (4 inch) diameter | | Special Features | Passive Ventilation | | Standby Power Shutoff | A | | Style | Classic | | Unit Count | 1.0 count | ## Product Details - **Brand:** Weiworld - **Colour:** White - **Electric fan design:** Exhaust Fan - **Material:** Acrylonitrile Butadiene Styrene, Stainless Steel - **Mounting type:** Wall Mount - **Power source:** Air Powered - **Product dimensions:** 15D x 16W x 20H centimetres - **Recommended uses for product:** Ventilating - **Room type:** Attic, Bedroom, Home Office - **Style:** Classic ## Images ![100 mm Through Wall Passive Air Vent Kit with Filter, Adjustable Fresh Air Intake, Extendable Duct & SS304 External Grille for Home, Bedroom, Attic (No Motor) - Image 1](https://m.media-amazon.com/images/I/71f3rPDtYGL.jpg) ![100 mm Through Wall Passive Air Vent Kit with Filter, Adjustable Fresh Air Intake, Extendable Duct & SS304 External Grille for Home, Bedroom, Attic (No Motor) - Image 2](https://m.media-amazon.com/images/I/71DoZkc8DtL.jpg) ![100 mm Through Wall Passive Air Vent Kit with Filter, Adjustable Fresh Air Intake, Extendable Duct & SS304 External Grille for Home, Bedroom, Attic (No Motor) - Image 3](https://m.media-amazon.com/images/I/71icnP79WDL.jpg) ![100 mm Through Wall Passive Air Vent Kit with Filter, Adjustable Fresh Air Intake, Extendable Duct & SS304 External Grille for Home, Bedroom, Attic (No Motor) - Image 4](https://m.media-amazon.com/images/I/81iV7EAxwPL.jpg) ![100 mm Through Wall Passive Air Vent Kit with Filter, Adjustable Fresh Air Intake, Extendable Duct & SS304 External Grille for Home, Bedroom, Attic (No Motor) - Image 5](https://m.media-amazon.com/images/I/71F3UYZ55FL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good product *by J***M on 28 July 2026* Easy to install, would recommend ### ⭐⭐⭐⭐⭐ Fits Well - Looks Good - Works As Desired *by A***R on 22 June 2026* I've installed this passive air vent in my little bathroom.

The three-level airflow control is easy to adjust based on what you need, and the mesh filter is simple to clean when required. It's quietly doing its job of improving air quality without any electricity costs, which makes it decent value for money. The build quality feels solid and the rain protection design seems sensible for outdoor weather exposure. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.mx/products/806226068-100-mm-through-wall-passive-air-vent-kit-with-filter](https://www.desertcart.mx/products/806226068-100-mm-through-wall-passive-air-vent-kit-with-filter) --- *Product available on Desertcart Mexico* *Store origin: MX* *Last updated: 2026-08-21*
