Having a water filter installed at home means an extra layer of protection for your drinking water, right? 🤔 The heart of a water filter – the filter cartridge – is what truly determines water quality! If you don't want to drink water full of impurities, you need to regularly replace your filter cartridge! But how often should a filter cartridge be replaced? Do different brands specify optimal replacement times?

Don't worry! Today, we're going to break down the filter cartridge replacement times for popular brands like ✨ Everpure, 3M, Brita, and Doulton ✨ so you can drink with peace of mind! 😉

🤔 Why and when should you replace a filter cartridge?

A filter cartridge is like a sieve. Over time, it accumulates scale, rust, and various impurities, which affects its filtering efficiency and can even lead to bacterial growth, posing a health risk! 😱 So, regularly replacing your filter cartridge is absolutely essential!

Generally speaking, when the following situations occur, it means you need to replace your filter cartridge:

1. Reduced water flow: Slower water flow indicates the filter may be clogged.
2. Deteriorated water quality: Tap water has an unusual taste or smell, or contains impurities, meaning the filter's purification efficiency has decreased.
3. Discolored filter cartridge: Some filter cartridges change color with use, at which point it's time to prepare for replacement.

4. Doulton

Doulton ceramic filter cartridges require regular cleaning. It is recommended to clean the surface of the ceramic filter cartridge with tap water and a sponge brush at least once a month (do not use any cleaning agents!). If the water quality in your area is poor, water flow may slow down after 2 to 3 weeks of use, requiring earlier cleaning of the ceramic filter cartridge.

Each ceramic filter cartridge can effectively filter 2,300 liters of water. For a family of 3-4 people, it is recommended to replace with a new filter cartridge approximately every 9-12 months (depending on usage and water quality). If the water quality in your area is poor, the filter cartridge may clog faster, requiring more frequent cleaning, and possibly needing replacement as early as every 6 months.

To ensure filter performance and water quality, it is recommended to replace with a new ceramic filter cartridge at least once a year.
