Why is my Brita Longlast Water Filter so Slow?

A Brita filter can be an excellent technique to remove impurities from tap water such as lead, asbestos, and other particle matter. However, the filtration rate of Brita filters can be excessively slow at times.

The Brita Longlast filter is certified to eliminate chlorine, cadmium, mercury, lead, asbestos and benzene particulate level 1. It’s also perfect for filtering out sediment particles in the water. However, it can be slow because it uses a different type of filtration than most other filters. Find out why your Brita Longlast filter is slow and fix it with easy steps.

Why is my Brita Longlast filter so slow?

The following are the most common reasons why your Brita Longlast water filter may be operating slowly.

Aeration from your tap water, bubbles stuck in the filter, excessive sediment levels, improper installation, low water pressure (for Brita faucet filters), or an outdated filter can all cause Brita filters to be slow.

Summarily, If your Brita Longlast filter is slow to drain and you haven’t changed the filter in a while, it may be because:

  • The filter was installed incorrectly.
  • It’s an old filter.
  • There are high levels of sediment in the water, which can clog up the pores of filters.

Brita claims that the problem is all about air bubbles getting caught in the filter. Brita also says that this issue can be resolved by replacing your old filters with a new one or installing them correctly for maximum efficiency.

This and more may be the reason why your Brita Longlast Water filter is slow. Although the Brita water filter is a great and inexpensive way to get clean filtered water, sometimes, the Brita Longlast filter does not work as expected, and the filtration rate may be slow. We have outlined 12 reasons why it is slow.

10 Reasons why your Brita Longlast water Filter is Slow

We’ll go over twelve particular reasons why your Brita Longlast filter can be too slow. Understanding this will assist you in troubleshooting and repairing your filter.

1. The Quality of water

Lower water quality causes filters to clog faster, and as a result, Brita’s Longlast flow rate decreases. Sediments such as pollutants, sand, clay, minerals, or rust may be present in significant concentrations in your tap water.

Normally, a fresh Brita Longlast filter takes 10-15 minutes to fill the reservoir; however, this time may be extended due to stuck particles. If your tap water has a high deposit level, we recommend that you install an additional filtration system before using the filter.

It is really simple to check the sediment levels in your tap water. Fill a glass with water and set it aside on the counter for 30 minutes. Finally, if you notice hazy impurities on the bottom of the glass, this is a sign that your tap water requires additional filtering.

Brita recommends replacing filters on a regular basis while using hard tap water, as hardness is one of the main causes of excessive sediment levels in the water.

2. The faucet’s aeration

Slow filtration, particularly while filling the reservoir, may create increased agitation from the tap. Remember to avoid turning on the faucet to a full stream while filling the pitcher.

Fill your pitcher with a calm and steady stream of water to ensure an uninterrupted filtration operation. Never allow the water stream to fall directly on top of the filter, as this improves its function.

3. Trapped air in the filter

Air bubbles trapped in the Brita filter can sometimes cause a slow filtration rate. To test it, place it in a water-filled dish or jar. If your filter floats, this indicates the existence of air bubbles in the filter.

4. The filter was not replaced in a timely manner.

If you want to get clean filtered water, you should change the filter on a regular basis. Otherwise, owing to long-term use, your Brita Longlast filter would be extremely slow to filter.

So, keep an eye on the filter change indication to monitor filter life and replace the filter as indicated by the indicator reading.

How often should you change your Brita Longlast filter?

Change Brita Longlast Filter every 6 months (every 120 gallons).

5. Sedimentation is very high.

If your tap water includes too many sediments, such as clay, minerals, pollutants, sand, or rust, the filter may become clogged. While Brita Longlast filters typically take 10-15 minutes to filter the reservoir, blocked particles can cause this to take longer.

If your tap water contains a significant level of sediment, it is recommended that you install an additional filtration system before using the Brita Filter.

Fill a glass of water straight from the tap and let it undisturbed on the counter for 30 minutes to see if it has too many sediments. A dirty residue on the bottom of the glass indicates that your water requires extra filtering.

Brita suggests replacing filters more regularly if your tap water is hard, as hardness is a major cause of high sediment in the water.

6. Particles have been trapped in the filter

If any particles become caught in the filter, gently spray water into the filter in the opposite direction to release the sediments. Keep in mind that doing this too frequently may cause damage to your Brita filter.

As a general rule, allow the water to completely filter the reservoir before refilling or pouring it.

7. Incorrect filter installation

If your Brita filter is not properly installed in the device, it may not filter water properly. This happens more frequently while the filter is being replaced. Read the instruction booklet attentively or ask a Brita professional to show you how to properly fit the filter.

It should be noted that the regular and Longlast filters have distinct installation techniques. Listen for a “snap and click” when you twist it into position in both circumstances. This means that the filter was properly placed. Additionally, ensure that the O-ring/gasket seal on your filtration device is securely seated.

8. Excessive application of the filter

The more water you consume, the sooner your filter has to be replaced. The filter replacement time (provided in the table above) is only an estimate – if you find yourself filtering 40 gallons in a month, for example, you should replace the filter more frequently (at least monthly).

For the greatest results, keep an eye on the filter change indicator.

9. Obstructed valves

If you used multiple valves, such as a dual check valve or a pressure limiting valve. You should also check to ensure that the pressure reduction valve is not set too low. The pressure limiting valve might become clogged, reducing the flow rate of your filter.

Make certain that it is linked to the water supply system before the filter.

10. Reduced water pressure from the faucet

If you use a Brita faucet filter, you should also check the tap water pressure to determine the source of the poor flow. The Brita faucet filter has numerous layers of filtration and filters the water using tap water pressure.

If the pressure is too low for some reason, the water may not flow properly, and your Brita faucet filtration will be interrupted. To fix this, check the water pressure in the faucet.

If your Brita filter is running slower than usual, first check for pipe leakage and silt in your pipeline. You may clean your faucet’s aerator to remove debris and keep it clean.

Low water pressure can also be caused by bent tubing, which you can remedy by contacting a plumber.

11. The filter has expired.

Brita water filters are available with a variety of mesh levels and filtration to filter pollutants of varying sizes and quality. It means that Brita filters defend against even the smallest impurities by providing high-quality water.

If your Brita filter produces brownish water with a strong odor, diverse chemicals taste, and the long-lasting filter functions slowly.

12. Defective indication

Filter change indicators are commonly seen on Brita pitchers, and they assist in determining the precise time to change the filter. A green light shows that the filter is working well, while a red light indicates that it is time to update the filter.

If the indication is not operating properly, the Brita filter replacement timer runs out and the Brita longlast filter eventually clogs.

As a result, you should replace the old filter and reset the indication by holding down the reset button for a few seconds.

When three lights begin to flicker at the same time, release the reset button; it is now complete. Always keep an eye out for the red dots in the upper right corner, which indicate that the indicator is working properly.

How do you fix a slow Brita Longlast Filter?

The Brita Longlast filter is a great option for those who want to reduce their carbon footprint, but it can be slow sometimes. This typically happens because the water that comes into the filter slows down and there are particles in the water that clog up your filter.

You can consider these solutions:

The Brita longlast filters are generally designed to last for a year, but sometimes your filter might be slow because it’s clogged. There is an easy way to fix this problem; make sure you put the filter in a jar filled with water and see if it floats. If not, lay the cartridge on its side and gently shake or stir until all of the sediment falls into solution then replace as usual!

Brita Longlast filters need to be maintained properly in order for them not to build up mold. It’s important that the filter is cleaned regularly, which can help avoid this problem from occurring.

Change the Brita filter at an appropriate time, gently tap the Brita filter under the water, keep the Brita filter under water and clean it to eliminate debris and sediments, flush water from the reverse side to push through the filter, and clean the particle.

If you’re noticing that your Brita Longlast filter is slow, it could be because of low-quality water. One way to speed up the process and improve filtration performance is by installing an additional filtration device like a faucet-mounted countertop reverse osmosis (RO) unit or pitcher/dispenser-style under sink RO system.

Remove the air bubbles from the Brita Longlast water filter. This can be resolved by simply soaking the filter for 15 minutes and releasing any trapped air bubbles with gentle squeezes while it’s soaking.

If this doesn’t solve your problem, you should consider replacing the filters on a regular basis to maintain optimal performance.

If you install an extra filtration device, your Brita Longlast filter will produce cleaner water in a shorter amount of time. This is due to the fact that many filters are slow because they don’t have enough internal capacity for large amounts of water and thus require more frequent cleaning when used with lower-quality tap or bottled water.

How to Reset Brita Longlast Filter

  • To reset the Brita Longlast filter indication, press and hold the STATUS button. Hold down the STATUS button for 6 seconds if using a Brita Longlast Filter (blue in color).
  • Do not press the release button until the green light next to LONGLAST+ FILTER has blinked three times on its own. This means the LONGLAST+ Filter mode (120 gallons) has been chosen.
  • If you mistakenly select the wrong mode, repeat step 1 until you properly select the mode that corresponds with the filter being utilized.
  • When you fill the reservoir and close the lid, the indication light will blink. Blinking green light shows that your filter is in good working order.
  • At any time, you can check the filter’s life status by pushing and releasing the Status button for 1 second. For 1 second, the light corresponding to your current filter state will blink.
  • When the filter is at 0% of its life, the red light next to REPLACE will blink, signaling that the filter should be changed. Reset the indication after replacing the filter.

There are numerous ways to track the filter life of the Longlast filter, depending on the model of pitcher or dispenser you own. A Longlast filter option is available on the electronic filter indication on certain newer models.

If you don’t have a model with the Brita Longlast filter indicator, a sticker with the Longlast filters is supplied. It has three holes, and the intention is to use it with the Standard filter indication, moving the sticker over one hole each time the indicator tells you to change your filter.

When you’ve finished the third hole, it’s time to change your filter.
