Why Is My Brita Filter So Slow: Reasons For Brita Filter Slow Working

Now I will elaborate on the issues causing the Brita filter to slow down along with solutions as promised:

1. Error In Filter Change Indicator

Brita Filter Change Indicator

Most Brita products have a filter replacement indicator to help determine the exact time to replace the filter. A green light on the status button indicates that the filter is working correctly, and a red light indicates the time to replace the filter. 

If the indicator does not work correctly for some reason, the Brita filter replacement time will expire, and the longevity filter will slowly clog. You can check this on your status button.

Therefore, you need to change the old filter products and press the reset button for a few seconds to reset the display. 

Release the reset button when the three lights start blinking simultaneously. Always note the red dot in the right corner. It means the indicator is working correctly, and you can be assured of clean and great-tasting water from your status button.

2. Brita Filter Slow? It’s The Air Bubbles!

Quite a few times, air bubbles get trapped inside the pitcher filter, leading to a slower filtration rate. You can check if any bubbles are trapped by dropping them in a hot water-filled sink or jar.

If the filter floats, it signifies that there is an air block. Soak the filter in cold tap water for 15-20 minutes exactly to remove the air block. Then rinse it under a running water distiller for 20 seconds and return it to its original position.

If that does not work, leave it under cold water and tap it on the side of the sink to loosen the foam. Check again to see if it sinks, then put it back in the pitcher.

3. You Didn’t Flush The Filter Before Use!

You may not know, but you can’t use your new Brita filter directly. Before the first use, you have to flush it for optimal performance.

For the Tap Faucet:

  • Install the tap filter and run the tap for 5 mins to flush the filter out.
  • Never drink the flushed water or use it in gardening. It can be harmful.

For the Standard, Longlast, Brita Stream, and Bottle faucets:

  • These filters require pre-soaking in clean water for 15-20 mins.
  • After that, wash beneath the strolling faucet water dispenser for 30 seconds.
  • Then, set up the Brita stream filter, fill the tank, and allow the filtered water to drain through the filter completely.
  • Discard this water at the least instances to make sure of its quality.
  • There can be carbon debris inside the number one fillings; however, don’t fear; it is far from an unusual place and harmless.

Important: Beverages like coffee and soda can slow down the filtration process of Brita filters. If you want your filters to work correctly, don’t try to “filter” any beverages through them.

4.  Brita Filter Needs Replacement

Delaying the replacement of the Brita Stream filter can slow down the filtration rate. The company has advised monitoring the life of the device by observing the filter replacement indicator.

Here’s what you need to do:

  • Replace it based on the reading of the filter life indicator on your respective products.
  • Green light assures a clean stream of water in your water dispenser.


You need to program the set-up individually for each filter to ensure a good performance using the green light. You can check the filter life indicator for information.

Check the sediment in tap water by examining a glassful of water using the filter change indicator.

There are various setups for standard, long load, and stream filters. Here is a quick list of how often you change the Brita stream filter by looking at the function and replacement time of each:

NameFunctionWhen to replace it
Brita Standard FilterRemoves mercury, copper, chlorine, cadmium, zinc2 months (every 40 gallons)
Brita Longlast FilterRemoves lead, mercury, benzene, chlorine, cadmium, asbestos6 months (every 120 gallons)
Brita Stream PitcherRemoves chlorine, particulates, trichlorobenzene2 months (every 40 gallons)
Brita BottleRemoves chlorine, particulates2 months (every 40 gallons)
Brita FaucetRemoves lead, mercury, chlorine, benzene, asbestos, particulates, trichlorobenzene, TTHMs4 months (every 94 – 100 gallons)

5. Your Valves Are Clogged!

If you set up numerous valves, like a twin, take a look at the stress-proscribe valve. You have to ensure that the stress-lowering valve isn’t always in too low a position in your Brita stream filter.

The stress proscribing valve may be clogged and affect your Brita stream filter flow rate. It may be linked to the delivery machine earlier than the filter, so make sure of this.

  • The green light indicates that it is suitable for use. However, at a yellow light on the status button, you may need to change your eroding cleaners and the filter’s groove.

6. You Haven’t Checked The Expiry Date Of Your Filter!

It’s safe to keep an eye on the expiry period of your filter. Do not buy extra filters so much in advance that they expire by the time you get to use them.

If you still miss the expiry date somehow, there are ways to detect that you should replace them. You can confirm this by observing the given conditions:

  • Brita’s long-lasting slow filtration or too-fast filter flow.
  • Low pressure.
  • It has a strange taste and a muddy color.
  • The presence of a bleach-like odor.

If you face any of these issues, you should immediately replace the filter cartridges to avoid health problems and ensure clean water quality.

7. Extreme Use Of Brita Filters

Used Brita filter

You will often use your Brita filter if you have a big joint family. Such excessive use reduces its lifespan, and you should replace it before the given duration.

You can refer to the table above to calculate the filter replacement time.

Note: The figures in the table are just an estimate for all the products. The actual usage may vary from person to person. 

If you have a standard Brita filter and use 40 gallons of water within a month, you will need to change the filter more often (at least once a month).

Moreover, your filter life indicator will notify you with a red light that it’s time to change the filter.

8.  Incorrect Filter Set Up

It’s pretty obvious. An incorrect setup can never deliver optimum performance, so study the assembly guide carefully.

You can also decide to ask a Brita stream personnel to do the work for you.

Note that the usual and Brita Longlast filters have different setups. In each case, pay attention to the “snap and click on” as you twist it into its place.

In addition, make sure the O-ring/gasket seal has been seated well in your filtration system.

9. Decreased Pressure From The Faucet

Apply this method if you are using a Brita faucet filter.

Know for certain:

The filtration process in the Brita filter depends on the tap water pressure. Low tap water pressure will slow down the filtration process, and you start blaming Brita rather than finding the cause for low water pressure.

I know that my readers are intelligent, so they don’t complain. They look for solutions. So, you can check for impurities and leakages in the pipeline to improve tap water pressure.

There are a few more things to do:

  • Remove impurities from the aerator of your faucet.
  • Check for plumbing problems.
  • Ensure that the pressure-reducing valve isn’t too low. 

10. High Sediment Concentration

High sediment concentration

I know you purchased Brita filters, thinking they would remove impurities. But as it turns out, Brita isn’t a superman.

Excessive sediments in tap water can clog the Brita filter, delaying filtration by around 20 minutes.

Here’s how to check sediments in tap water:

Fill up a glass of water directly from the tap and leave it on the counter for 3-5 minutes until you see a green light.

If you find muddy deposits at the bottom of your product’s bottle, it means that you need to filter the water again to improve its quality.

Why Is My Brita Filter So Slow: FAQs

How fast should a Brita filter work?

The speed of filtration depends on your filter health or how well you maintain it. Some Brita pitcher models filter water in 1.25 minutes, while others may take upto 15 minutes. So on average, the Brita pitcher filters water in around 10 minutes.

How to increase the lifespan of Brita filters?

By keeping your Brita filters clean, you can easily prolong their lifespan. Additionally, taking care of your filter ensures that it functions correctly. So, just replace the charcoal periodically and store it in a clean and dry place away from sun exposure.

How to tell if your Brita Filter is faulty?  

You will eventually know when your Brita filter is faulty as it contains the following warning signs – 

1. The water is smelly.
2. The filter is parched.
3. The taste changes.
4. Presence of mold in the filter

How long does Brita Pitcher Filter last?

Different Brita Pitcher filter models have different replacement timelines. Mostly, 2 months or 40 Gallons is the average time for many households to change their Brita filter. Other models can last for 4 to 6 months. It may vary a little according to your water demands. So, check your water quality periodically to ensure a consistent, clean water supply.

Why is my Brita filtering so fast? 

It may be due to the following reasons:

1. Faulty or Expired Filter – If Brita is filtering too fast, it is a sign that there may be some cracks or leaks within the filter. Expired filters, too, lose their filtration capability and let water pass quickly. The water’s taste, smell, or appearance will tell you something is wrong.
2. Your area’s water is already very clean – It is usually rare though possible. If the water supply has no or minor contaminants, it will filter out very quickly through your Brita filter.
3. Filter is still brand new – Brita filters contain porous charcoal, which takes time to adjust. Water will pass quickly through a new filter as the pores are not clogged yet.

If you suspect missing parts in your filter, immediately convey your concerns to Brita’s customer support.

Finally, all I have to say is:

Brita offers good customer service and delivers some of the best filtration solutions on the market right now. Defects can be present both in the unit you are using or in your water supply.
