What is a Cartridge Pool Filter?
A cartridge pool filter uses a filtration system made up of thin, clothlike material to filter out particles and contaminants from your pool water. The cartridge can be removed periodically for washing, to remove dirt and debris, and then can be replaced with a brand new one every year or so.
Unlike sand pool filters that require frequent backwashing, cartridge filters just have to be taken out and sprayed off with a garden hose. So although cartridge filters are more expensive than sand filters, you’re going to save a lot of money on water used for cleaning.
What Types of Cartridge Pool Filters Can You Buy?
Cartridge pool filters come in all shapes and sizes but all will more-or-less do the same thing. The two main types of cartridge pool filters are ones made specifically for in-ground and above-ground pools, although many can work with either model.
The most important factor here is the size (water volume) of your pool. Above-ground pool cartridge filters are smaller and meant to clean smaller volumes of water than their in-ground counterparts.
What to Consider When Buying a Cartridge Pool Filter
Cartridge pool filters are great all-around filters for residential and commercial pool owners. So although all cartridge pool filters are going to do the same thing, there are definitely ones that are better for certain jobs.
Before you take the plunge, here are a few things to consider to make your decision-making process as simple as possible.
What Size Filter Do You Need?
Determining your filter size ahead of time is a smart first step to avoid accidentally purchasing the incorrect model. Start by taking a look at your pool pump to find out the flow rate or GPH (Gallons Per Hour) that the pump can accommodate.
When looking for a cartridge filter for your pool, the standard gauge is 100 square feet of filter for every 10,000 gallons of water. So, if you have a 25,000-gallon pool, you need at least 250 square feet of filter.
When sized correctly, cartridge filters don’t clog up as quickly, allowing more water to flow through for optimum cleaning potential. If a cartridge filter is sized properly, you may be able to run it the entire season without needing to clean it.
Size Matters… When it Comes to Microns
Microns are a unit of measurement used to measure impurities. Just to give you an idea of size, a micron is a unit of length equal to one millionth of a meter (1/1,000,000 m), or 0.0000394 of an inch. The human eye can see something as small as 35 microns without magnification.
Swimming pool filters are rated according to the size of microns they capture. So the lower the number on a filter’s micron rating, the better it’s going to be for cleaning your pool water. If a filter could capture particles down to 1 micron, that would be an awesome filter.
So when it comes to water purification, the smaller the particles you are able to remove, the cleaner the water is going to be. It’s as simple as that.
Cartridge pool filters are generally rated to filter particles down to 10-20 microns. If pool water purity is your goal, make sure to look out for cartridge filters that are rated on the lower end of the scale.
How Often Do You Have to Replace the Filter?
Some above-ground cartridge filters need to be replaced weekly and some only once every other year. Make sure to read the manufacturer’s guidelines and consider the cost of replacement filters when making your purchase so as not to get a nasty shock in the future.
At one time, it was not unusual for a cartridge pool filter to last 2+ years. However, the increased use of sunscreens, hair products, and deodorants by swimmers take a toll on the filter, decreasing its lifespan to roughly 1 year at the most.
Pro Tip: One of the best ways to extend the life of your cartridge pool filter is to have swimmers rinse or shower off before getting into the pool. This can really save your filter from all of the chemicals in personal products that wear it down over time.
What’s Your Budget?
Price is always a major consideration when it comes to buying a piece of equipment or household appliance. Remember that you plan to have this for years to come, so you want to make sure the quality is there. You’ll find that the price of cartridge filters varies significantly based on filter size (area), flow rate (GPH), and general durability.
Finding a cartridge filter that fits your pool, your maintenance schedule, and your budget is the goal.
