How often should I replace my carbon filter? The complete guide
A properly functioning carbon filter is crucial for the purity of your drinking water. Regularly replacing this component in your water filter system ensures you can always enjoy clean, tasty water. On average, carbon filters should be replaced every 6 to 12 months, but this can vary.
The exact replacement frequency depends on several factors. With heavy use, such as in larger households, you may need to replace your filter after just six months. For smaller households or less intensive use, a carbon filter can last up to a year. It's always better to replace it preventatively than to wait until the water quality noticeably deteriorates.
Regular replacement is important not only for the taste of your water, but also for your health. A saturated carbon filter can no longer effectively remove harmful substances, significantly reducing the quality of your drinking water.
What are the signs that my carbon filter needs replacing?
Recognizing the signs that your carbon filter needs replacing can help you maintain optimally purified water. One of the most noticeable signs is a change in the taste or smell of your water. If your water suddenly tastes different or has an unpleasant odor, this could indicate a saturated filter.
Visual changes can also be a warning sign. Water that becomes cloudy or shows visible particles indicates reduced filter capacity. Also, pay attention to your water's flow rate. A noticeably slower flow rate could indicate your filter is becoming clogged by accumulated contaminants.
- Change in taste or odor of the water
- Cloudy water or visible particles
- Reduced flow rate
- Recurring limescale on surfaces
- Expiry of the recommended period of use
Some advanced systems, such as our PureAqua water filters, have indicators that indicate when replacement is necessary. These can be based on time or the amount of filtered water.
How does water usage affect the lifespan of my carbon filter?
The amount of water flowing through your filter daily directly affects how long your carbon filter lasts. The more water is filtered, the faster the filter will become saturated. For example, a four-person household will need to replace its filter more often than a single-person household.
Besides the number of users, the water quality in your region also plays a significant role. In areas with harder water or higher levels of contaminants, a filter needs to be replaced more often than in regions with relatively clean water.
| Usage situation | Recommended replacement frequency |
|---|---|
| Small household (1-2 persons) | Every 10-12 months |
| Average household (3-4 people) | Every 6-9 months |
| Large household (5+ persons) | Every 4-6 months |
| Areas with hard water | Replace 30-40% more frequently |
The type of carbon filter you use also makes a difference. Advanced systems like our 'The Source' water filter system are designed to work more efficiently and therefore have a longer lifespan, while still removing up to 99% of unwanted substances.
