Above ground pools are a popular way to cool off during the hot summer months. A crucial component of keeping an above ground pool in top condition is the pool filter. But how long does an above ground pool filter last? In this article, we’ll answer that question and provide some helpful tips to maximize the life of your pool filter.

Understanding Pool Filters

Before we dive into the question of how long an above ground pool filter lasts, it’s essential to understand how pool filters function. The primary function of a pool filter is to remove debris and contaminants from the pool water. The filter does this by using a filtering media, such as sand, diatomaceous earth (DE), or cartridge.

Sand Filters

Sand filters are the most common type of pool filter used in above ground pools. Sand filters work by passing water through a bed of sand. The sand traps debris and contaminants, allowing clean water to pass through and return to the pool. Sand filters require regular backwashing to dispose of the trapped debris and contaminants.

Diatomaceous Earth (DE) Filters

A DE filter uses a filtering media made from the fossilized remains of tiny aquatic organisms called diatoms. As water passes through the DE media, it captures even smaller particles than sand filters can capture. DE filters must be backwashed and the DE media replaced annually.

Cartridge Filters

Cartridge filters work by using a pleated polyester filter cartridge to trap debris and contaminants as water passes through. Cartridge filters require less maintenance than sand or DE filters, as they don’t need backwashing. The cartridges need to be cleaned regularly and replaced every two to three years.

So, how long does an above ground pool filter last?

The answer to this question depends largely on the type of filter you’re using, the frequency of maintenance, and the quality of the filter.

Sand Filters – On average, a sand filter can last between five and ten years. However, with proper maintenance, such as regular backwashing and chemical cleaning, a sand filter can last even longer. It’s essential to replace the sand in the filter every three to five years, as the sand can break down and fail to trap debris and contaminants effectively.

Diatomaceous Earth (DE) Filters – A DE filter can last between seven and ten years if properly maintained. The DE filter must be backwashed regularly and the DE media replaced every year.

Cartridge Filters – A cartridge filter can last between two and three years if maintained correctly. Cleaning the cartridges regularly and replacing them every two to three years will ensure the filter lasts as long as possible.

Maximizing the Life of Your Above Ground Pool Filter

To maximize the life of your above ground pool filter, follow these simple tips:

1. Clean the filter regularly – Sand and DE filters require regular backwashing to dispose of trapped debris and contaminants. Cartridge filters require cleaning every few weeks.

2. Replace filter media – Replace the sand in sand filters every three to five years, replace the DE media annually, and replace cartridges every two to three years.

3. Proper chemical balance – Maintaining proper chemical balance in your pool will help prevent excessive debris and contaminants in the water, reducing the workload on your pool filter.

4. Don’t overwork the filter – Ensure your pump isn’t too powerful for your filter, as this can lead to excessive debris and contaminants in the pool water.

5. Keep the pool clean – Regularly skimming the pool with a net and vacuuming the pool floor will reduce the workload on your filter.

In Conclusion

In summary, the lifespan of an above ground pool filter varies depending on the type of filter, the frequency of maintenance, and the quality of the filter. With proper maintenance, an above ground pool filter can last for many years, providing clean and clear pool water. Maximize the life of your filter by regularly cleaning it, replacing filter media, maintaining proper chemical balance, avoiding overworking the filter, and keeping the pool clean.
