Find Your Fit: How to Buy the Right Pool Filter Cartridges

What You Should Consider When Choosing Pool Filter Cartridges

When it comes to maintaining the cleanliness of your pool, the filter cartridge plays a crucial role. The cartridge is responsible for removing dirt and debris from the water, keeping it clean and appealing. But choosing the right filter cartridge isn’t always easy. Here’s what you should consider when selecting the right filter cartridge for your pool.

Type of Filter

The most important factor to consider when selecting a filter cartridge is the type of filter you need. Pool filter cartridges come in two basic types: pleated and non-pleated. Pleated filters use a series of pleats to increase the surface area of the filter, helping it to trap more dirt and debris. Non-pleated filters are made of a single layer of fabric, which is more susceptible to clogging but also cheaper to replace.

Size of Filter

The size of filter you need will depend on the size of your pool. Generally speaking, the larger the pool, the larger the filter cartridge you’ll need. Cartridge filters come in a variety of sizes, from small, single-cartridge filters to large, multi-cartridge filters. Make sure to measure your filter housing to ensure you’re getting the right size filter.

Flow Rate

The flow rate of a filter is important because it determines how quickly the water is filtered. The higher the flow rate, the faster the water will be filtered. If the flow rate is too low, the filter won’t be able to keep up with the demand and the pool will become dirty. Make sure to check the flow rate of the filter cartridge you’re considering before making a purchase.

Durability

Durability is another important factor to consider when choosing a filter cartridge. Different brands offer different levels of durability, so make sure to do your research. Some brands offer cartridges that are designed to last up to a year, while others may only last a few months.

Price

Price is always a consideration when it comes to purchasing pool supplies, and filter cartridges are no exception. Generally speaking, pleated filters are more expensive than non-pleated filters, but they also last longer. Make sure to compare prices before making a purchase to ensure you’re getting the best value for your money.

When it comes to selecting the right filter cartridge for your pool, there are several factors to consider. Make sure to consider the type, size, flow rate, durability, and price of the filter before making a purchase. Doing your research beforehand will help ensure you get the right filter for your pool.

Frequently Asked Questions (FAQs)

1. How long do pool filter cartridges last?

Pool filter cartridges typically last around 2 to 3 years, according to most manufacturers. However, it's important to follow the recommendations of the specific filter cartridge manufacturer to ensure optimal performance and water filtration.

2. How do I know what pool filter cartridge to buy?

To determine the right pool filter cartridge to buy, you should match the dimensions of the new cartridge with your existing one. Take out the old cartridge and measure it using a tape measure to ensure a proper fit for replacement.

3. How do I know if my pool cartridge is bad?

If you notice that your pool is not as clean as it used to be, such as changes in water color, smell, or appearance, it may be an indication that your pool cartridge needs to be replaced. It's important to address any issues with your filter to maintain clean and clear pool water.

4. Should I clean or replace pool filter cartridge?

While pool filter cartridges can be cleaned, it's important to note that each cleaning cycle can cause wear and tear on the cartridge's fibers, which can reduce its effectiveness. It is recommended to replace the cartridge when the pressure gauge consistently reads above 8 PSI or when the cleaning frequency increases.

5. What size pool cartridge do I need?

The size of the pool cartridge you need depends on the size of your pool. Generally, a pool with a capacity of 15,000 gallons can use a 150 to 200 square-foot cartridge filter. For pools with more than 25,000 gallons of water, a 400 square-foot filter is recommended.

6. What is the easiest pool filter to maintain?

Sand filters are often considered the easiest to maintain. They require backwashing when the pressure gauge reads 10 PSI above the normal operating level. With proper water chemistry, a sand filter media can last for 5 to 10 years, making it a convenient option for pool maintenance.
