What’s the Difference Between Carbon Filters and Sediment Filters?

Clean and safe water is essential for every home, and having the right filtration system ensures your family can enjoy it. Two of the most common types of water filters are carbon filters and sediment filters, but many homeowners aren’t sure how they differ or which one they need. Understanding the unique benefits and purposes of each filter can help you make informed decisions for your home’s water system.

At Superior Plumbing & Drains, we help homeowners choose and maintain water filtration systems that deliver the best results. Here’s what you need to know about carbon and sediment filters.

What is a Sediment Filter?

A sediment filter is designed to remove physical particles from water, such as:

• Sand
  
• Dirt
  
• Rust
  
• Silt
  

These filters are typically made from pleated polyester, cellulose, or a combination of materials that trap particles as water passes through. Sediment filters are often the first stage in a multi-stage water filtration system because they prevent larger debris from reaching other filters, like carbon filters or reverse osmosis membranes.

Benefits of Sediment Filters:

• Protect plumbing and appliances from damage caused by debris
  
• Improve the lifespan of more sensitive water filtration components
  
• Reduce cloudiness in water for cleaner use in drinking, cooking, and bathing
  

Sediment filters do not remove chemicals, odors, or dissolved contaminants—they are purely physical filters for particulate matter.

What is a Carbon Filter?

A carbon filter is designed to remove chemical contaminants and impurities that affect the taste, odor, and safety of water. These filters use activated carbon, which has millions of tiny pores that trap and absorb impurities.

Carbon filters are effective at removing:

• Chlorine and chloramine
  
• Volatile organic compounds (VOCs)
  
• Pesticides and herbicides
  
• Certain heavy metals
  
• Unpleasant tastes or odors
  

Unlike sediment filters, carbon filters do not remove large particles. Instead, they focus on chemical contaminants and improving the water’s taste and smell. This makes them ideal for drinking water applications, such as kitchen faucets, refrigerators, and under-sink filtration systems.

When to Replace Filters

Regular maintenance is crucial for optimal performance:

• Sediment filters: Replace when you notice reduced water pressure, visible debris, or after 6–12 months depending on water quality.
  
• Carbon filters: Replace when you detect a change in taste or odor, or according to the manufacturer’s recommended schedule, usually every 3–6 months.
  

Neglecting filter replacement can lead to reduced water quality, clogged systems, and increased wear on appliances.

While some homeowners can replace basic filters themselves, a professional can ensure your water filtration system is properly installed and maintained.
