Baffle filters are stainless steel range hood filters. These grease filters are constructed with three-sided baffles that alternate to enhance airflow and grease filtration when your hood is operating.

What is a Baffle Filter

Aluminum and stainless steel are common materials for making baffle grease filters. The baffle filter’s spaces promote the best possible air circulation. The filter can collect more grease. After that, the grease may drain through the baffles and into the catch basin.

Commercial extractor fans often use filters called baffle filters to stop fires from spreading through the filter baffles. Different materials are used for its construction depending on the anticipated temperatures.

There has been a recent uptick in demand for stainless steel baffle filters, making them a common fixture in both professional and home kitchens.

How do baffle filters work

To create a baffle filter, baffles are interlocked to provide a circuitous path through which the grease may flow. After sliding down the filter’s smooth vanes, oil particles end up in the canopy’s collection chambers. Because of this, the likelihood of accumulations that impede ventilation is reduced.

Benefits of baffle filters

Baffle filters provide additional advantages in eliminating oil and grease from smoke and allowing for smooth exhaust.

  • The baffle filters prevent the kitchen from engulfing flames if there is a flame or flare-up from the range.
  • Hood canopies with baffle filters do a great job of drawing in air and distributing it equally.
  • Baffle filters don’t need as much upkeep as other types of filters, such as mesh/cassette filters or charcoal filters.
  • Another perk is that baffle filters may be put in the dishwasher.
  • Baffle filters are more long-lasting than mesh or charcoal filters since they are constructed of stainless steel or aluminum.

What are the different types of baffle filters?

It may come as a surprise to some, but not all-powerful filters are made of stainless steel. While we typically refer to bathroom filters as stainless steel, the truth is that they come in galvanized and aluminum materials. Below are some of the different types of baffle filters.

Stainless steel

Stainless steel filters have a very aesthetically pleasing look and are the best option for open kitchens with visitor views. In addition, stainless steel hood filters give the highest permanent protection against rust and corrosion and are ideal for commercial appliances.

Galvanized baffle filters

Galvanized filters are heavier and more robust than aluminum, but their dull surface prevents them from being used in open kitchens where aesthetics are essential. On the other hand, they are the least expensive and most corrosion-resistant filters.

Aluminum baffle filters

Aluminum baffle filters are more aesthetically pleasing than galvanized alternatives while being cost-effective. In addition, aluminum baffle grease filters provide a smooth, seamless surface that allows grease to flow into hood collecting troughs, providing safe, reliable, positive flame barrier protection.

When choosing the best hood filter material, think about how visible your kitchen is and what kinds of appliances you’ll be using it with. Since they are not on display to customers, galvanized grease baffle filters are a popular budget option in commercial kitchens. In addition, galvanized metal hood filters are very resistant to corrosion and wear.

How do you clean baffle filers?

Baffle filters are a popular choice for commercial kitchen extractor filters, but maintaining them correctly over time is essential to ensure they continue to perform as intended and don’t break down on you. Have a professional kitchen filter cleaner do the job for the greatest results. That way, you can be certain that your baffle filters will last longer. In addition, regular filter maintenance is necessary to reduce risk.

When should you replace your range hood baffle filter?

The filters in your range hood should be replaced if you see any dents, holes, rust, or other damage on the baffles. Baffle filters are exposed to corrosive acids and alkalis when cooking, and metal may corrode under these conditions. Depending on your use, a baffle filter may last for decades or just a few years.

To improve the operation of your range hood and decrease the danger of a fire, it is advised that you replace the baffle filters if you see rust on them. In addition, a malfunctioning range hood might be hazardous to your health.
