The Essential Guide to Changing Your Range Hood Filter

May 15th, 2024 | Broan-NuTone
A kitchen is the heart of a home, a place where meals are prepared, and memories are made. But did you know that the air quality in your kitchen is just as important as the food you cook? When you cook, the method and type of food, along with the stove or range used, can emit various substances such as nitrogen dioxide, carbon monoxide, CO2, particulate matter, and other potential pollutants into the atmosphere. That's where your range hood filters come into play.

Why Change Your Filters?

Whether using an aluminum, charcoal, or hybrid filter, filtration plays a crucial role in maintaining clean air in your kitchen. Regardless of your filter type, they are designed to trap and remove various pollutants, such as grease, smoke, and debris, ensuring you have better indoor air quality (IAQ).  Regular maintenance and replacement of filters are essential to prevent the accumulation of these pollutants which can lead to reduced airflow and potential fire hazards. It’s important to follow the recommended schedule for cleaning and replacing filters to ensure they continue to function effectively and provide a safe healthy atmosphere.

What Types of Filters Are There? 

  • Aluminum Filters are unique in that they can be cleaned by the user, which is not a feature commonly associated with the other types of filters. This self-maintenance aspect helps prolong their life and efficiency.
  • Charcoal Filters neutralize odors and purify the air, acting as a defense against harmful particles, especially for range hoods that recirculate air back into the kitchen. They absorb odors and airborne chemicals, ensuring the air remains clean and free from contaminants. Over time, the activated carbon becomes saturated and can no longer effectively trap pollutants, leading to a decrease in air quality and an increase in odors. Therefore, it's recommended to replace charcoal filters every six months to ensure they continue to perform efficiently and protect your indoor air environment.
  • Hybrid Baffle Filters are designed to trap grease and particles, a feature they share with aluminum filters, but they also prevent these from entering the ventilation system, which is a unique aspect of their design. Their replacement is crucial not just for efficiency but also for safety reasons, as they can pose a fire hazard if not maintained.

Each filter has its own set of maintenance requirements and replacement schedules to ensure they function effectively and maintain a clean and safe kitchen environment.

The Benefits of Regular Replacement

  • Optimal Air Quality: Regularly changing your filters means the air in your kitchen remains clean, reducing the risk of respiratory issues and other health problems.
  • Efficiency: Clean filters mean your range hood can work at its best, saving you money on energy bills and preventing potential damage to the appliance.
  • Peace of Mind: Knowing that your kitchen is a haven for clean, breathable air can make cooking and dining a more enjoyable experience for everyone.

Final Reminder

Maintaining your range hood filters is not just a matter of routine, but a proactive step towards a healthier kitchen environment. Many of our hoods come equipped with a filter reminder button, which is set to a 30-hour usage timer, to prompt you to check and clean your filters. The frequency of cleaning may vary depending on how often you cook, but as a general guideline, non-duct filters should be replaced every six months, while aluminum and baffle filters should be cleaned at least semi-annually or when they appear grease-laden. Don't wait until it's too late; a simple reminder can go a long way in preserving the air quality of your home and the efficiency of your range hood.
