Range Hood Filters: Charcoal vs. Aluminium

You rely on your range hood to remove impurities from the air while you cook in order to keep the air quality in your kitchen high. In a ductless model, the filter is the portion of your range hood that actually captures the impurities when the appliance is in operation, so it is arguably one of the most important parts of the system.

Modern range hoods are made with two different types of filters: aluminium mesh and charcoal. If you’re shopping for a new range hood, understanding the differences between the two can help you choose the best appliance to complete your kitchen. Here are four points of comparison between the two filter types:

1. Function

Aluminium filters capture fine particulates inside of mesh that works similarly to a spider’s web. Pieces that are larger than the tiny openings in the mesh become trapped inside and are not able to re-enter the air.

Charcoal filters use a special material called activated charcoal, which is a carbon-based compound that has been treated with oxygen to make it very porous. Impurities that are attracted to carbon become absorbed through the pores of the mineral and are kept trapped inside.

2. Effectiveness

If you do not frequently cook with grease, an aluminium filter should be more than capable of keeping the air clean.

Charcoal filters will generally be more effective at removing fine particulates from the air due to their porous nature.

3. Longevity

Aluminium filters are designed for constant reuse. They are never thrown away unless they become damaged.

A charcoal filter lasts for only a set number of months and then must be thrown away. If you forget to replace the charcoal filter on time, you will suffer a decrease in indoor air quality.

4. Maintenance

Every 3 to 4 months, you should remove the aluminium filter and wash it with warm soapy water.

A charcoal filter never requires cleaning once it is installed.
