Why Is My Brita Filtering So Slow

Why Is My Brita Filtering So Slow

Is your Brita filter moving at a snail’s pace? Several factors can cause a Brita filter to filter slowly, including clogged filter cartridges, improper maintenance, and water quality issues. Don’t worry; there are steps you can take to troubleshoot and resolve the problem.

Reasons Why Your Brita Longlast Water Filter Is Slow

Here are 10 potential reasons why your Brita Longlast water filter might be filtering water slowly:

Clogged Filter:

Over time, the filter cartridge can become clogged with sediment, debris, and contaminants, reducing water flow. If the filter is nearing the end of its lifespan or if you’ve been using it for an extended period, it may need to be replaced.


Air bubbles trapped in the filter cartridge or pitcher can impede water flow. Ensure that the filter cartridge is properly seated and that there are no air pockets trapped inside. Try filling the pitcher with water and allowing it to sit for a few minutes to release any trapped air bubbles.

Cold Water Temperature:

Brita filters typically work more slowly with cold water compared to room temperature or warm water. If you’ve been using cold water, try using water at a slightly warmer temperature to improve filtration speed.

Improper Installation:

Make sure that the filter cartridge is installed correctly in the pitcher or dispenser. If the cartridge is not seated properly or if the pitcher is not assembled correctly, it can restrict water flow.

High Levels of Contaminants:

If the water source has high levels of contaminants or sediment, the filter may clog more quickly, leading to reduced flow rate. Consider using a pre-filter or sediment filter to remove larger particles before they reach the Brita Longlast filter.

Soaking Requirement:

New Brita Longlast filters may require soaking before first use to activate the filtration media. Ensure that you’ve soaked the filter cartridge according to the manufacturer’s instructions.

Low Water Pressure:

If your home has low water pressure, it can affect the flow rate of the Brita Longlast filter. Check for any issues with your plumbing system or water supply that could be contributing to low water pressure.

Filter Life:

If the Brita Longlast filter is nearing the end of its lifespan, it may become less effective at filtering water and may slow down filtration speed. Replace the filter cartridge as recommended by Brita to ensure optimal performance.

Contaminant Buildup:

Certain contaminants, such as mineral deposits or limescale, can accumulate on the filter cartridge over time, reducing its effectiveness and slowing down water flow. Regularly clean the filter cartridge according to Brita’s instructions to prevent buildup.

Quality of Water Source:

The quality of your tap water can also affect the performance of the Brita Longlast filter. If your water source contains high levels of impurities or sediment, the filter may become clogged more quickly, leading to slower filtration speed.

By considering these potential reasons, you can troubleshoot why your Brita Longlast water filter is filtering water slowly and take appropriate steps to improve filtration speed and performance.

How Do You Fix A Slow Brita Longlast Filter?

To address a slow Brita Longlast filter, start by considering its usage duration. If it’s been in use for an extended period or nearing its recommended replacement time, replacing the filter with a new one may be necessary to restore optimal filtration speed.

Additionally, visually inspect the filter cartridge for any signs of clogs or blockages, and gently rinse it under cold water to remove any accumulated sediment or debris.

Properly soaking a new filter according to the manufacturer’s instructions before use can also activate its filtration media and enhance performance.

Ensure the filter is correctly installed in the pitcher or dispenser, without any air pockets trapped inside, and verify that your water temperature is conducive to efficient filtration.

Running water through the system for a few minutes can help flush out any residual particles, while checking and addressing any low water pressure issues in your home is essential for optimal flow rates.

Regular maintenance, including periodic cleaning of the filter and pitcher or dispenser, is crucial for preventing future slowdowns and maintaining consistent performance.

If troubleshooting steps don’t resolve the issue, contacting Brita customer support for further guidance or warranty assistance may be necessary.

How To Reset Brita Longlast Filter

Resetting a Brita Longlast filter typically involves replacing the filter cartridge with a new one. When inserting a fresh filter, the filter indicator light on your Brita pitcher or dispenser will often reset automatically, signaling that the new filter is recognized and ready for use.

However, some Brita models may feature a manual reset button or indicator light that requires pressing and holding to reset after replacing the filter.

It’s important to consult your Brita user manual for specific reset instructions tailored to your model. Following the manufacturer’s guidelines ensures that you reset the filter indicator accurately, maintaining accurate tracking of filter usage.

Once reset, verify that the indicator light or display reflects the reset and acknowledges the installation of the new filter.

If you encounter difficulties with resetting the filter indicator or have questions, referencing the user manual or contacting Brita customer support can provide further assistance and troubleshooting guidance.

The Reason Behind Why Brita Filters Are So Slow

The slowing down of Brita filters can often be attributed to several factors. Primarily, as the filter cartridge accumulates sediment, debris, and contaminants from the water over time, it tends to clog, thereby restricting water flow.

Additionally, nearing the end of its lifespan, the filter’s efficacy diminishes, resulting in slower filtration. Air bubbles trapped within the filter cartridge or pitcher can also impede water flow.

Furthermore, Brita filters typically function more sluggishly with colder water temperatures, as the filtration media contracts, diminishing its effectiveness.

High levels of contaminants in the water source can hasten clogging, exacerbating the slowdown. Incorrect installation of the filter cartridge or assembly issues with the pitcher can further hamper water flow.

Lastly, low water pressure within the home’s plumbing system can significantly impact the flow rate of the Brita filter.

Regular maintenance practices such as replacing the filter cartridge and cleaning the pitcher can help mitigate these issues, ensuring consistent and optimal performance from the Brita filter.
