how long does an inground pool filter last

Inground pools are a popular choice among homeowners who want to relax and cool off during the hot summer months. One of the key components of an inground pool is the pool filter. How long a filter lasts can depend on a variety of factors, including the type of filter, the size of the pool, and how well it is maintained. In this article, we will explore the lifespan of an inground pool filter.

Types of Inground Pool Filters

There are three main types of inground pool filters: sand, cartridge, and diatomaceous earth (DE). Each type has its own advantages and disadvantages.

Sand filters are the most common type of pool filter for inground pools. They work by passing water through a layer of sand, which catches dirt and debris. Sand filters are low maintenance and can last up to 7 years with proper care.

Cartridge filters use a pleated cartridge to filter pool water. They are more efficient than sand filters and require less water to operate. Cartridge filters can last up to 5 years with proper care.

Diatomaceous earth (DE) filters use powdered diatomaceous earth to filter out impurities in the water. DE filters are the most efficient type of pool filter and can last up to 10 years with proper care.

Factors that Affect the Lifespan of an Inground Pool Filter

The lifespan of an inground pool filter can vary based on a variety of factors. Some of the most important factors to consider include:

Size of the pool: The larger the pool, the more strain is put on the filter. A larger pool may require a larger filter or more frequent filter cleanings.

Pool usage: The more often the pool is used, the more frequently the filter will need to be cleaned or replaced.

Maintenance: Proper maintenance is crucial for extending the life of a pool filter. Regular cleaning and maintenance can help prevent clogs and damage to the filter.

Water chemistry: The chemical balance of the pool water can affect the lifespan of a filter. High levels of chlorine or other chemicals can damage the filter over time.

Signs that Your Inground Pool Filter Needs to be Replaced

Even with proper care, inground pool filters will eventually need to be replaced. Some signs that it may be time to replace your pool filter include:

Decreased water flow: If the water flow from your pool jets is weaker than usual, it may be a sign that the filter is clogged or damaged.

Dirty pool water: If your pool water is consistently dirty, cloudy, or discolored despite regular cleaning and maintenance, it may be a sign that the filter is not functioning properly.

Visible damage: If you can see visible signs of damage to the filter, such as cracks or tears in the filter material, it is time to replace the filter.

Conclusion

The lifespan of an inground pool filter can vary depending on a variety of factors. Proper maintenance and care can help extend the life of a filter, but eventually, all filters will need to be replaced. By paying attention to the signs that your filter needs to be replaced, you can ensure that your pool remains clean and safe for swimming.
