Are you asking “Why is my Brita filter so slow”? If yes, you are in the right place as I’m going to discuss the for slow Brita filter and how to fix it.

Brita water filters is great, it removes chemicals, sediments, mold, and other contaminants from your water, but just like everything in this world, they are not perfect and can develop a fault.

If you have ever purchased a Brita filter that starts out great but becomes very slow after a few uses, read on.

In this article, I will explain why your Brita filter is so slow and how to fix the slow Brita filter.

The following are some of the reasons your Brita filter is so slow.

10 Common Reasons for Slow Brita Filter

1. Home Water Quality

If your water contains too many types of sediment, such as clay, minerals, sand, pollutants, or rust, the particles can clog the filter.

Despite the fact that Brita filters usually take about 10-15 minutes to filter the tank, the clogged particles may slow the filter if your water contains a high level of sediment.

It is recommended that you install an extra filtration system before using the Brita filter. You can check if your water contains too much sediment by filling a glass of water straight from the tap and letting it sit on the counter for 30 minutes.

If you find mud deposits at the bottom of the glass, this is an indication that the water needs extra filtration.

2. Air Trapped in the Filter

The filter in the pitcher can occasionally become clogged with air bubbles, which slows down the filtration process. Dropping your filter into a sink or jar of water will help you confirm if the filter has bubbles stuck inside.

If it floats, then there is an air block, and to remove it, soak it in cold water for 15-20 minutes and rinse the filter under running water for 20 seconds and reinstall it.

3. Damaged Brita Filter

Usually, Brita standard filters should be replaced every three months and Longlast filters every six months. Rarely, and sometimes even before the predicted period, filters develop faults for no apparent reason. One of the signs related to this problem is that the device will slow filtration.

4. Clogged Brita Filter

If your Brita filter drips slowly and the Longlast filter has visible particles. You can simply wash away the sediment by gradually spraying water directly from the opposite direction. Do this with care, as there may be a chance of damaging your Brita filters and possibly causing algae growth.

Consider allowing the water to drain out of the entire tank before refilling the tank or pouring the pitcher.

5. The Filter Has Reached Its Lifespan

The Brita water filter has several mesh levels and filtration to remove contaminants of different sizes and qualities. This means that Brita filters offer the best flavor and cleanest water while also protecting against the smallest impurities.

If your Brita Longlast filter performs slowly, that means your filter has reached its lifespan. That’s when you should change the filter right away.

6. The Filter Was Not Pre-soaked or Flushed Before Use

You might not be aware of this, but your new Brita filter cannot be used directly. For best performance, you must flush first before use.

For the faucet, install the faucet filter and run the faucet for 5 minutes to rinse the filter. Never drink the washed water or use it for gardening. It could be harmful.

For Standard, Longlast, Brita Stream, and Bottle faucets, these filters require a pre-soak in water for 15 to 20 minutes. Then wash under the stopcock dispenser for 30 seconds. Next, install a Brita filter, fill the tank and allow the water filter to drain completely. Dispose of this water as little as possible to be sure of its quality.

7. Low Water Pressure from the Tap (for Brita Faucet Filter)

The Brita faucet filter passes water through two layers of filtration using the pressure from the tap. This might not work if the pressure is too slow. Check your tap’s water pressure. If it’s too slow, check for leaks and sediment in your pipe. Make sure the pressure-reducing valve is not set too low; clean the faucet aerator to remove dirt.

Also, Low water pressure may also occur due to tube flexing. In this case, check for plumbing problems.

8. Clogged Pipes or Valves (for Brita Faucet Filter)

If you installed multiple valves, such as a twin, check valve, or stress proscribing valve. You need to check your Brita filter to make sure the stress-proscribing valve isn’t always in an incorrect position.

9. Filtering Liquids Other Than Water

Curiosity sometimes makes some people try to filter other liquids such as soda, coffee, and cold drinks like lemonade from their pitcher filter. This can make your Brita filter drain very slowly because this liquid contains many types of colors, particles, and chemicals.

You should refrain from using your filter in this manner. The filter is designed to filter water and should only be used for this purpose.

10. Faulty Electronic Filter Light Indicator

The majority of Brita filters come with a filter replacement indicator to help you know when to change the filter.

A green light on the status button means the filter is operating well, and a red light means it needs to be replaced.

The Brita filter replacement time will expire, and the filter will slowly clog if the indicator does not work correctly for whatever reason. You can view this on your status button. So, to reset the display, you must replace the old filter and briefly press the reset button.

  • To clean the particle and force it through the filter, flush water from the other side.
  • From time to time, you can check the quality of your water to make sure it is not too dirty.
  • If you get poor quality water, I suggest installing an additional water filtration system.

How to Make Brita Filter Faster

  • To remove any trapped air bubbles, gently tap the filter or flush it.
  • Spray water on the filter to flush out sediment and debris.

How to Fix Clogged Brita filter

To get rid of the air block, soak it erect in cold water for about 15-20 minutes. Then wash the filter under running water for 20 seconds and reinstall it.

If that doesn’t work, gently tap the filter against the side of the sink while holding it under water to release bubbles.
