What Is a Septic Tank Filter?  

A septic tank filter is a crucial component in the overall functioning of septic tanks, as it plays a vital role in preventing solid waste particles from entering the drain field. This helps maintain the efficiency and longevity of the septic system, reducing the likelihood of clogs and costly repairs. The filter works by trapping solids within the tank while allowing liquid effluent to pass through and continue to the drain field. 

Do You Need a Septic Tank Filter?  

The short answer is yes. While your septic system can operate without a filter, you would be wise to install one. A septic tank filter prevents solid waste particles from entering the drain field. Without a filter, these solids can clog the drain field, leading to system failure and costly repairs.  

Benefits of Using a Septic Tank Filter 

There are several reasons you should consider installing a septic tank filter, including:   

  • Improving your system’s efficiency. Septic tank filters increase the overall efficiency of your septic system by preventing solid waste particles from entering the drain field, thus reducing the risk of clogs and system failure. 

  • Extending your system’s lifespan. By keeping solid waste out of the drain field, filters can help extend the life of your septic system and reduce the need for costly repairs. 

  • Protecting the environment. Preventing solid waste from entering the drain field helps protect the environment by reducing the risk of groundwater contamination.\ 

  • Protecting your health. A properly functioning septic system with a filter reduces the risk of wastewater overflowing onto your property, which can lead to health hazards. 

Factors to Consider 

If you are considering whether to install a septic tank filter, you should consider the following factors:  

  • The type of septic tank you have. Different septic tanks may require different types of filters. Conventional septic systems typically use gravity to separate solids from wastewater, while alternative systems may use pumps or other mechanisms. Make sure to choose a filter that is compatible with your specific septic system.  

  • Your household size. The size of your household can impact the type of filter you need. Larger households produce more wastewater and solid waste, which may require a more robust filter. Consider your household's daily water usage and the amount of waste generated when selecting a filter. 

  • Your budget. Septic tank filters come in various price ranges, from affordable options to high-end models. Consider your budget when choosing a filter, but keep in mind that investing in a quality filter can save you money in the long run by reducing the need for costly repairs and system maintenance.  

Types of Septic Tank Filters & Their Uses  

There are various types of septic tank filters, such as:  

  • Effluent filters. These filters are installed at the outlet of the septic tank, preventing solids from entering the drain field. Effluent filters are suitable for both conventional and alternative septic systems and come in various sizes and designs to accommodate different flow rates and waste loads. 

  • Outlet baffles. Outlet baffles are simple devices that create a barrier between the solid waste and the outlet pipe, allowing only liquid effluent to pass through. They are most effective in smaller households with lower wastewater volumes. 

  • Sand filters. Sand filters use layers of sand to trap solid waste particles as water passes through. They are suitable for larger households or properties with limited space for a drain field, as they can help reduce the size of the required drain field area. 

  • Screen filters. These filters use a fine mesh screen to capture solid waste particles before they enter the drain field. Screen filters require regular cleaning but provide a high level of protection against clogs.  

How Often Should Septic Tank Filters Be Cleaned?  

You should clean your filter regularly according to the manufacturer's recommendations, usually every 6-12 months. Regular cleaning prevents clogs and maintains system efficiency. 

After three to five years, your filter may need to be replaced. Check to see if the filter has signs of wear or damage. A damaged filter can allow solids to enter the drain field, increasing the risk of system failure.
