Buying Guide: Pool Cartridge Filter System
Although all cartridge filters do the same job, there are some which are better than others. That is why you need to know how to choose the ideal model for your swimming pool by answering these questions.
1. What Size Filter Does My Pool Need?
Knowing the perfect filter size before you start to look for one can ensure you choose the correct model. Look at your facility’s pump to figure out the G.P.H. or flow rate it can accommodate.
From there, get a cartridge filter that can match 100 sq. ft. with 10,000 gallons of water. Thus, if your pool can hold about 25,000 gallons, buy a filter with approximately 250 sq. ft.
Things to note: Your cartridge filter will never clog if you size it correctly, and it will allow more water to pass through. It might be possible to run if for the whole season without cleaning it.
2. What Size of Dirt Do I Want to Filter?
The other thing to consider is the impurities you wish to filter out, measured in microns. A micron is equal to 1/1,000,000 m or 0.0000394 of an inch.
Your eyes can see particles of up to 35 microns without using a magnifying lens. Cartridge filters are rated according to the microns they can trap.
The lower the rating, the better the filter can clean your pool. If possible, you should get a cartridge filter that can trap particles of about one micron.
Something to note: Cartridge pool filters are often rated to remove particles of about 10 microns.
3. How Regularly Should Will I Replace the Cartridge Filter?
It is possible to get a product that needs to be replaced every seven days while the other takes one to two years. Read the brand’s instructions when buying these systems to avoid the nasty shock in the coming days.
A few years ago, a cartridge filter could last for over two years. That has changed due to the increased use of hair products, deodorants, and sunscreens by swimmers.
Professional tip: You can extend your system’s life by ensuring that the swimmers shower or rinse off before taking a swim.
4. What is My Budget?
You should always consider your budget before you decide to buy a pool product or accessory. With that said, remember that you want a cartridge filter that you can use for years, so it should be quality.
A quality product might be more expensive than a lowly constructed one.
