Pool owners don’t always give enough consideration to the type of filter they buy for their pool, and that’s quite a shame because there are some significant differences between different filter types. For example, the best cartridge pool filters are capable of filtering out 100% more debris out of the pool’s water than a sand filter can do. And when it comes to keeping your pool sparkling clean, that’s quite a significant improvement in water filtering.
Having a great cartridge pool filter not only means cleaner water, however. It also means that the pool owner doesn’t have to add as many chemicals to their pool, which saves them a significant amount of money over the lifetime of the pool. That’s why we’ve listed some of the best pool filters that use a cartridge system, so that pool owners can take their pool water filtering up to the next level.

A Guide To Cartridge Pool Filters
Cartridge pool filters are a great way for a pool owner to keep their pool clean, as long as they buy the right one for their pool. How does a person buy the best cartridge pool filter? Well, all they have to do is either select one from our above list or read this guide. In the guide that’s before you, we’re going to find out what consumers should consider when they’re buying a new cartridge filter.
The Pros & Cons Of Cartridge Pool Filters
The war between sand pool filters and cartridge pool filters have been raging for decades now. Some people proclaim that sand filters are the best and others say that cartridge filters are the best. Who is right? While we won’t get into the specifics of which type of filter is better, we can tell our readers all of the reasons why we like cartridge filters. We can also tell them some of the things that we don’t like about them. An example of both the pros and cons of these filters can be found below.
The Pros Of Cartridge Filters
- They remove particles as small as 10 microns.
- The larger surface area of their media screens out more dirt particles.
- No backwashing is required to use them.
- They’re easier on the pool’s pump.
- They’re ideal for above ground pools.
- They reduce energy costs by lowering pump pressure.
The Cons Of Cartridge Filters
- They have a higher initial cost.
- They’re not practical for extremely large pools.
- They need to be replaced every few years.
- The filter has to be washed every 6-months of sooner for best results.
Choosing The Best Cartridge Pool Filter
The next thing we want to talk about is how to purchase a cartridge pool filter system. And in our opinion, it’s not all that difficult to find a cartridge pool filter if the consumer takes a few moments and factors in their needs and the size of the pool. Having stated that fact, let’s get started with one of the most important things to consider—the filter flow rate of the cartridge.
Consider Filter Flow Rate
The filter flow rate is extremely important to consider. Get a filter that doesn’t meet the basic flow rate of the pump and it can easily become overwhelmed. Unfortunately, figuring out the filter flow rate isn’t very simple and it requires considering the size of the pool and comparing it with the pump’s operating rate. Below are some examples of what we mean.
- 10,000 Gallon Pool With A 3/4-HP Pump Requires A Filter Size Of 100-200 Square Feet.
- 30,000 Gallon Pool With A 2-HP Pump Requires A Filter Size Of 400-500 Square Feet.
- 45,000 Gallon Pool With A 2.5-HP Pump Requires A Filter Size Of 500+ Square Feet.
Consider A Durable Outer Casing
The next thing to think about is how durable the outside of the filter casing is. The casing should be made from durable metal or plastic, so that it can stand up to the rigors of the elements season in and season out.
Consider Additional Features
It’s also a good idea to think about some of the additional features that a person might need their filter to have. Although not every pool owner will need every feature we have listed below, it is a good place to start so consumers can figure out which features they may need.
- Rapid-Release Air Relief Valve
- Top Manifold Configuration For Hydraulic Performance
- Easy-Spin Unions For Easy-Installation
- A Check Valve
- Locking Knobs That Replace Older Clamp-Based Locking Systems
