How Range Hood Filters Work

Range hood filters work by capturing and trapping airborne particles, such as grease, smoke, and odors, as the cooking fumes pass through them. The specific working mechanism may vary depending on the type of filter used, but the overall goal remains the same – to remove pollutants and ensure clean air in the kitchen.

Mesh/Aluminum Filters: Mesh or aluminum filters work by creating a barrier of fine mesh or aluminum panels. These panels have small gaps that allow air to pass through while capturing grease particles. The grease particles become trapped in the mesh or on the aluminum surface, preventing them from recirculating into the kitchen air. Regular cleaning is necessary to maintain the filter’s efficiency.

Baffle Filters: Baffle filters use a series of metal layers arranged in a zigzag pattern. As cooking fumes pass through the filter, the grease particles change direction due to the baffle design. This change in direction causes the particles to collide with the metal layers, where they become trapped. The gaps between the baffle layers allow clean air to pass through, reducing the risk of recirculating pollutants. Baffle filters are relatively easy to clean, as the grease particles can be washed away with water and detergent.

Carbon/Charcoal Filters: Carbon or charcoal filters are designed to remove odors from the air. These filters consist of a layer of activated charcoal or carbon. When cooking fumes pass through the filter, the charcoal or carbon molecules adsorb and trap odor-producing molecules. This helps to minimize the presence of cooking odors in the kitchen. Carbon/charcoal filters are often used in combination with other filters, such as mesh or baffle filters, to provide a comprehensive filtration system.

Disposable Filters: Disposable filters are typically made of paper or non-woven fabric and are designed to be replaced regularly. These filters work by capturing grease particles as the cooking fumes pass through the filter material. While they may not provide the same level of long-term durability as other types of filters, disposable filters offer convenience, as they can be easily discarded and replaced with fresh ones.

Permanent Filters: Permanent filters are made of durable materials, such as aluminum or stainless steel, designed for repeated use. They work in a similar way to mesh filters by trapping grease particles as the air passes through the filter. Unlike disposable filters, permanent filters require regular cleaning to maintain their effectiveness. They can either be washed by hand with hot water and detergent or placed in the dishwasher for easy maintenance.

Regardless of the type of range hood filter you have, it is important to clean or replace it regularly to ensure optimal performance.
