In this article, we will discuss the topic of the operational resources of filter cartridges and its efficiency in household water filters. We will focus primarily on how long a filter cartridge lasts, the costs of its replacement, and how it affects the quality of water treatment. The ratio of operating costs to filtration efficiency should be the key criterion when choosing a water filter.
Types of Filter Cartridges
Every water filter requires regular maintenance. In household systems, two main types of filtering elements are used: accumulative and distributive. Additionally, there are soluble elements, such as polyphosphate salt, and partially soluble ones, e.g., mineralizers.
An accumulative filter cartridge typically includes three pre-filters in reverse osmosis systems and a post-filter. Distributive cartridges are osmotic membranes. All require replacement after their resource is exhausted. Each type of cartridge has specifications regarding its working time or volume, but in practice, this may vary.
Service Life of Pre-Filters
Pre-filter cartridges have a defined lifespan, usually specified in liters or months of use. Unfortunately, the actual service life can differ significantly from the manufacturer’s declaration. Reasons include, for example, the condition of local water supply installations or the quality of tap water.
Sometimes, a sudden pressure drop releases a large amount of rust into the pipes, significantly burdening the filter cartridge. In such cases, it is advisable to immediately cut off the water supply to the filter and run the contaminated water through a regular tap. Otherwise, cartridges can clog and lose their effectiveness within minutes.
Factors Affecting Cartridge Lifespan
Two key factors influence the cartridge resource:
- Degree of water contamination;
- Volume of water flowing through the filter.
In classic systems like Polski Filtr or PAqua, it is recommended to monitor cartridge condition at least until the first replacement, then follow the recommended schedule. In Premium-class systems, cartridge usage is automatically monitored, and the filter stops working when the cartridge is exhausted.
Membrane Lifespan in Osmotic Systems
The osmotic membrane is the most important element of a reverse osmosis system. Its durability and effectiveness depend directly on the condition of the pre-filters, which protect the membrane from mechanical impurities and chlorine. If the cartridge is not replaced in time, the membrane can be damaged, worsening drinking water quality.
In Premium systems, the membrane is protected—the filter automatically stops working once the cartridge is used up. This helps the membrane last longer without risk of failure.
Why Choose Premium-Class Systems?
Filter cartridges in Premium systems are more expensive but guarantee greater safety and longer system lifespan. When the cartridge resource ends, the filter stops working—this is the best protection for the membrane. If you care about high water quality and long-term savings, investing in such a solution is worthwhile.
Summary
The filter cartridges and its efficiency depends on water quality and usage intensity. Premium systems offer better protection, and their cartridges last longer. Regular cartridge replacement ensures effective filtration and protects your family’s health.
