Depending on their type, water filters have different maintenance requirements. Some filters require more monitoring than others, and some level of maintenance is required for all types of water filter systems. Whether it’s a UV lamp that has to be replaced in the case of UV water filters, or a yearly RO membrane replacement in the case of reverse osmosis water filters, under no circumstances should you ignore the maintenance instructions that come with your water filter. The quality of your filtered water is highly dependent on the proper observance of the filter replacement, filter handling and water filter monitoring instructions.

Water filter maintenance best practices

In this article, we will present some of the most common water filter maintenance best practices that you should abide by:

  1. Regular filter cartridge replacement

Water filter cartridges cannot be used forever, and depending on the type of filter media and filter brand, filter cartridges have to be replaced periodically. Filter cartridges will usually last anywhere from 3 months to 1 year, however, always consult your water filter’s user guide to find out how often should you replace your water filter cartridges. To make sure you always replace the filters at the required time intervals, it’s best to enrol in a filter replacement reminder programme that will notify you via e-mail when to change your filters. This way, you don’t run the risk of missing a filter replacement date.

  1. Special filter replacement conditions

Be advised that complex water filters like 6-stage reverse osmosis water filter systems operate with several filter cartridges, which may need to be replaced at different intervals. For example, the pre-filters in the Pure-Pro Quick Change 6-Stage Reverse Osmosis System with Alkaline Filter have to be replaced every 6-months, while the post-filters need replacing every 12 months. Similarly, the RO membrane will last for 2 years before it has to be replaced. A periodic TDS (total dissolved solids) rejection test is recommended to be performed to help you in deciding whether it’s time to replace the membrane.

  1. Monitor the taste of your tap water

Changes in the taste and odour of your tap water may be a sign that you have to replace your filter cartridge, especially if the changes persist. The quality of your tap water may change, and you may have to replace the filter cartridge even before the recommended filter replacement date. Therefore, it’s a good idea to always keep an extra set of replacement cartridges at hand. If the changes in your tap water persist even after you’ve replaced your filters, make sure your contact your water supplier to report the problem.

  1. Handle with care

Some filters are made of materials that may not be shock-resistant, thus, if dropped, internal cracks and surface cracks may appear. This is especially a problem with sealed cartridges or ceramic filter candles. Handle your filters with care, and if you accidentally drop them, we advise against using them. To be on the safe side, it’s best if you throw them away, and use a new cartridge instead.

The observance of the above-listed maintenance best practices will ensure that your filtered water is always up to par, and that your water filter system can work at its full potential.
