What type of grease filter should you use?

A properly maintained grease filter is an essential part of any kitchen. It helps evacuate odors, grease, smoke and other contaminants that are present in the ambient air. As an indispensable part of your range hood, the filter must receive regular maintenance to ensure that it functions correctly. If the filter is clogged or dirty, it will allow grease and other residue to accumulate in the ventilation ducts, creating a fire hazard.

But what kind of filter should you use? Keep reading for tips on choosing the most suitable filter for your range hood.

Types of grease filters

Range hood filters are available in three different materials: stainless steel, aluminum and galvanized steel.

The one you choose will depend on your needs. Stainless steel filters are the most durable. With a shiny appearance, they’re perfect for open kitchens, as they can withstand frequent cleaning. However, they’re also expensive. Aluminum is a more pliant material, but aluminum filters aren’t permitted for use in commercial range hoods, as they pose a greater fire hazard. The advantage, however, is that they can be replaced more often. Galvanized steel filters, which are the ones that are most commonly used, offer a good balance between price, fire resistance and grease extraction performance. However, galvanized steel filters can become tarnished after a few cleanings, although this doesn’t affect their performance.

Another important aspect to take into consideration is the way the filter is assembled. They can be either riveted or welded. What’s the difference? Riveted filters tend to be more flexible, while welded filters are more durable and resistant because of their rigidity. We use welded filters.

Carbon filters for effective cleaning

Increasingly popular, carbon filters work with a ventilation fan. While other types of filters simply expel the air to the outside of the building, carbon filters capture the heat, grease particles, smoke and odors in the air, filter them out and then return the air to the kitchen. You should note, however, that carbon filters often require an eco-friendly system, which can be quite expensive.

Types of carbon filters

You’ll find several different types of carbon filters on the market. Here are a few of them.

Foam filters: sold in the form of a square of foam that can be cut to the desired dimensions, they’re nicknamed “universal carbon filters.”

Granular filters: these come in the form of round or rectangular cartridges. Each cartridge has specific dimensions and contains variable quantities of activated carbon. The granules can be purchased separately to limit the waste that would result from having to replace the entire filter.

Laminar filters: offered optionally, especially on certain premium hood models, these filters are among the most efficient. They’re also one of the most expensive types of carbon filters. In order to use them, you will have to get a specific recycling setup.
