which is a better pool filter sand or cartridge

Introduction:

When it comes to keeping your pool clean and clear, you need an efficient pool filter. Two main types of pool filters are sand and cartridge filters. Both have their own advantages and disadvantages, and it can be challenging to choose between them. In this article, we will discuss which is a better pool filter sand or cartridge.

What is a Sand Filter Pool?

Sand filter pools are the most common type of pool filter used in residential swimming pools. They use silica sand or solid blocks of zeolite as a filter medium. The sand is placed inside the filtering tank and water is pumped through it. As the water flows, the sand traps dirt and debris, filtering out impurities as small as 40 microns.

Pros of a Sand Filter Pool:

1. Low Maintenance: Sand filters require little to no maintenance as sand only needs to be backwashed and replaced every few years, unlike cartridge filters that require cleaning every 6-12 months.

2. Cost-Effective: Sand filters are the most affordable pool filter. They are also the most cost-effective option in terms of filtration and backwashing.

3. Long-Lasting: Sand filters have a lifespan of 5-7 years on average, making them more durable than cartridge filters that only last 3-5 years on average.

Cons of a Sand Filter Pool:

1. Inefficient Filtration: Sand filters can only filter particles down to 40 microns in size, making them less efficient than cartridge filters that can filter down to 10-15 microns.

2. Slow Flow Rate: Sand filters offer a lower flow rate than other pool filters, meaning they take longer to filter the same amount of water.

3. Heavy Sand Load: Sand filters can become overloaded with debris, which can continue to grow and circulate in the pool.

What is a Cartridge Pool Filter?

Cartridge pool filters consist of a cartridge made of polyester or pleated paper that is placed inside a filter housing. Water flows through the cartridge, trapping dirt and debris in the folds. Cartridges have a finer filtration capacity than sand filters and can capture particles as small as 10-15 microns.

Pros of a Cartridge Pool Filter:

1. Efficient Filtration: Cartridge filters offer superior filtration compared to sand filters, trapping finer particles.

2. High Flow Rate: Cartridge filters offer higher flow rates than sand filters, meaning they can filter the same amount of water in less time.

3. Low Pressure: Cartridge filters operate at low pressure, which can help save energy costs.

Cons of a Cartridge Pool Filter:

1. High Maintenance: Cartridge filters require regular cleaning, which can be time-consuming for pool owners.

2. High Cost: Cartridge filters are more expensive to purchase upfront than sand filters.

3. Shorter Lifespan: Cartridge filters only last 3-5 years on average compared to sand filters, which can last up to 7 years.

Conclusion:

Choosing the right pool filter can be challenging, but it is critical to keeping your pool clean and clear. Sand filters are affordable and low maintenance, but they offer lower filtration and longer filtration times. Cartridge filters, on the other hand, are more expensive and require more maintenance, but they offer superior filtration and higher flow rates. Ultimately, the best pool filter for you depends on your pool size and how often you use it.
