Why is it important to replace your hood filters?

A kitchen environment can become filled with smoke, grease, unpleasant odors, and heat. You can avoid these factors by installing a range hood that purifies and recirculates air carefully. A range hood contains several different components, filters being an important aspect of this appliance.

They should be cleaned and maintained well to ensure your hood works well. Filters have a limited lifespan, so you’ll need to replace them eventually. Commercial hood filters should be cleaned once every few months. If you have a mesh component, clean it every week to ensure there’s no grease accumulation.

Why is it important to replace hood filters?

Modern filters are often made from resilient materials like aluminum, stainless steel, or mild steel. All these materials can last for decades without problems, especially if they’re maintained well. Like all materials, filters are subject to wear so you’ll have to replace them eventually. Here are some reasons why it’s important to do so in a timely fashion:

Damage to the hood – Poor quality or damaged filters can cause damage to a hood, forcing you to replace it earlier than necessary. Avoid this by replacing filters as soon as you can, before damages become too expensive to repair.

Inefficient operation – Filters have a big impact on a hood’s performance, which is why it’s important to maintain them. Without good quality filters, the kitchen air won’t be filtered properly. Clogged/damaged filters also strain the system, which consumes more power in turn.

Quality of indoor air – Damaged filters don’t purify air thoroughly enough, which creates an unhealthy environment inside a kitchen. As your hood can’t remove the smoke, grease, or other particles from kitchen air, employees are forced to breathe these substances in during work hours. That can have a big impact on their health.

Fire hazard – Accumulated grime is highly combustible, which is why filters need to be cleaned regularly. If the build-up is too stiff and can’t be removed, we recommend replacing filters to avoid fire. An accidental fire can destroy your hood and even the kitchen.

As you can see, there are several reasons why you should consider replacing old filters. It’s also a good idea to replace mesh filters with baffle ones, which are safer to use and easier to maintain.

When should you replace filters?

Most are designed to last for several years, even decades, without much problem. Because of this, many clients forget to check their filter’s condition and don’t realize it is damaged. Here are some signs you should keep an eye out for:

Stubborn grime – Sometimes grime solidifies completely and just doesn’t come off. This places your system at risk as greasy particles are combustible, which is a fire hazard. If the filters have too much grime, replacing them is a good idea.

Weak, damaged sections – It’s not wise to continue using old filters if some sections have become weak. Rusted sections, perforations, chipped metal, etc., can all cause extensive damage to your hood, which costs money to repair.

Dents and tears – It’s rare to find dents or tears in filters but that does happen sometimes. Torn or dented components don’t operate at optimal efficiency, so they should be replaced.

Commercial kitchens get the filters cleaned every month, or less, especially if they prepare a high volume of food. Replacement depends largely on use, but we recommend getting your hood inspected at least twice a year to avoid problems.
