Water filter cartridges lose their effectiveness over time, and delaying their replacement is what most often brings back the old taste of the water. In this guide we go through the main signs that it is time to change the cartridges, then give a clear replacement schedule for each filter in our store, with the price of the cartridge or pack.

Key takeaways

The most common signs: reduced water flow, the return of a chlorine taste or a salty taste, the return of odor
Do not wait for the signs to appear: each filter has a set replacement date
The Tank Pro 6-function cartridge is changed every 4 months, and the 3-stage filter every 6 months
5-stage and 7-stage filters are changed in two rounds: after 6 months, then after 12 months

Five signs that it is time

1. Reduced water flow

When the cartridges fill up with sediment, less water comes out of the filter’s dedicated tap. On reverse osmosis units, the tank also takes longer than usual to fill.

2. The return of a chlorine or salty taste

If the taste of chlorine comes back in the water, or the salty taste returns with a reverse osmosis filter, it is a sign that the cartridge is no longer doing its job as it used to.

3. The return of odor

Carbon is what limits odors, and when its cartridges become saturated the odor gradually returns.

4. Cloudy water or sediment in the glass

If particles or cloudiness appear in the water after the filter, the sediment cartridge is full.

5. The white deposit returns in the kettle

In filters that reduce limescale, such as the 5-stage and the Tank Pro 6-function, a white deposit that quickly returns in the kettle may mean the cartridge has reached the end of its life.

These signs are only useful as a warning. It is better to change the cartridges on schedule without waiting for them to appear.

What if you do not know your filter model?

Send us a photo of your device on WhatsApp, and we will confirm the right cartridge before you order.

What happens if you delay the replacement?

The cartridge’s efficiency gradually declines, so the old taste returns and the flow drops. In some filters this also affects the remaining stages, so it is best to keep to the schedule.

How to order the cartridges

In the store you will find the Tank Pro 6-function filter cartridge and the annual pack for the 7-stage filter, among others. Delivery is free to all cities in Morocco and payment is on delivery.
