How often should I replace my water filter?
It’s a good question, but there’s no obvious answer. Regardless, we will attempt to respond to it in this blog entry. We’ll go over frequent issues, such as when to replace the water filters and how to identify when it’s the correct time to do so. We’ve also prepared a handy list of the most popular water filters and filtering beds, along with their approximate service life.
Why should I replace my water filters at all?
Replace your water filters for hygiene reasons – it is as simple as that. Even if the water has been treated and sanitised, water is the ideal medium for bacteria to thrive and reproduce. Filters for household drinking water remove hazardous bacteria but do not neutralize them. They build up in the filter, which can lead to bacteria overgrowth and recontamination of the water. This scenario is highly likely if you haven’t replaced or disinfected your water filter in a long time.
The effectiveness of the water filter is the second argument. All water filters, whether active carbon, softening bed, RO membrane, or ultrafiltration membrane, wear out and lose their ability to properly cleanse water with time. It’s a good idea to replace your drinking water filters on a regular basis to keep them in good working order.
What factors affect the filter’s service life?
Any water filter’s service life is determined by two factors:
- Is there a lot of pollution in the water?
- Is the water filter in use well-suited to the water quality and demand on-site?
Water filters are worn out quickly by cloudy, iron-rich water. The faster the water is replaced, the more iron and suspended particles it contains. Otherwise, they reduce the softening resin’s ability to treat. It holds true for all forms of water filters, including yarn and melt-blown cartridges. Also, keep in mind the filter micronage. The higher the treating accuracy, the more the filters’ accuracy is mismatched with the water quality.
The type of filter is determined by water quality. The more polluted the water, the more critical it is to select the appropriate treatment process. As a result, we always recommend that you do basic water tests to determine its composition and then select a suitable filtration system based on the results.
If the filter or softener is not fitted to the water demand, the softening bed will last less. When a family of four uses a 15-litre softener, the softening resin needs to regenerate more frequently, causing it to wear out faster.
When should I replace the water filter?
As you may be aware, a filter’s performance and longevity are determined by many factors. Based on our own views and experiences, we’ve compiled a list of filter cartridges and beds that should be replaced after a certain period of time.
So, how do you know when it’s high time to update your water filter?
- melt-blown filter, yarn filter, sediment filter, active carbon – every 6 – 12 months
- in-line cartridges in reverse osmosis systems – every 12 months
- RO and ultrafiltration membrane – every 36 months
- carbon cartridges post-filters – every 12 months
- softening bed – every 10 years
- mesh filters – every few years, with regular cleaning
- UV lamp – every 12 months
Water quality is critical because it directly influences the filter’s lifespan. The more impurities it has to filter, the less efficient it will be and it will need to be replaced sooner.
How can you take care of your water filters and make them last longer?
The foundation for the filter’s long and trouble-free operation is proper maintenance. The associated manual will advice on how to care for the filters.
When dealing with highly contaminated water, following the filter manufacturer’s guidelines makes it easier to maintain the filters. Using a mechanical in-line filter is smart. Any water treatment and filtration systems are installed downstream of the mechanical filter. It protects water-operating devices from mechanical impurities that diminish the efficacy of water filters and may cause damage.
Check the condition of the in-line filter cartridges on a regular basis, especially the yarn, carbon, and softening cartridges. If you use disc filters, remove any deposits on them regularly. Program more frequent regenerations and sanitize the bed in the case of home water treatment stations.
