Best Pool Cartridge Filter

By John V. Saum | Last Updated: June 16, 2022

Owning a swimming pool does not come cheap. You need to invest a good amount of money in constructing a pool and, at the same for its maintenance, to keep it clean and sparkling all year round. Also, pool maintenance requires a lot of work. You must check all the moving pool’s moving parts regularly. The good thing is that by choosing the best pool cartridge filter, you can cut your work and complete them fast.

Cartridge pool filters might be just what you need to make it easier to take care of your pool. Let’s look at what choices are available. A good pool filter keeps the water in your pool clean and free of dirt and other things that could be harmful. We researched the best options, looking at suction power, compatibility with pool systems, and how easy it was to install and clean. Here are some of the best ones.

What Is A Cartridge Pool Filter

A cartridge filter uses a thin, cloth-like material to filter your pool’s water. After cleaning the cartridge once a year, you can replace it. Cartridge filters don’t need to be cleaned as often as sand filters. Because cartridge filters are more efficient, you’ll save money on cleaning water.

How We Chose the Best Pool Filters

For this guide, we evaluated dozens of pool filters based on various factors. The filter of a swimming pool should be easy to maintain and long-lasting. In order to protect ourselves from the sun’s harmful ultraviolet rays and the cold, we selected models made of durable, molded plastic. We opted for models whose designs make it simple for the end-user to do maintenance fast. Instead of needing to remove a lot of gear to reach the cartridge, we used cartridge filters with quick-release fittings. Sand and D.E. filters have multiport valves that allow the operator to switch between back-flowing and winterizing modes of operation effortlessly.

What to Look for Before Buying Best Cartridge Pool Filters?

When searching for the ideal filter for one’s swimming pool, there are a number of aspects that one must take into consideration, including the filter’s type, flow rate, and compatibility. Continue reading to find out more information about these and other characteristics of pool filters.

Pool Filters Type

Buyers need to consider these three types of filters, each of which has a set of advantages and disadvantages.

Sand

A sand pool filter draws water into a sand-filled tank. The water collects any 20-micron-or-larger filth as it moves through the area. Even though it’s easier to maintain and cheaper than other filters, the best pool sand filter can’t remove microscopic particles.

Side-mounted and top-mounted sand filters exist. Top-mounted sand filters are cheaper and take up less space than side-mounted filters, but changing the sand in a side-mounted filter is easier because you don’t have to disconnect the pipes.

D.E. (Diatomaceous Earth)

D.E. filters, also known as diatomaceous earth filters, work similarly to sand filters, except they pump water through a fine powder that can trap particles as small as 5 microns. The D.E. filter is the most effective because it can remove minute particles from the pool. However, it’s more expensive than cartridges or sand filters and requires the most maintenance.

Cartridge

Filters that use cartridges have a removable filter and catch dirt and debris as it moves through the filter. Cartridge filters are an efficient filtration method because they may capture particles as fine as 10 microns in size. Maintaining a cartridge filter is not a particularly difficult task because it can be removed and washed clean with a hose.

Rate of Flow and Total Capacity

Filters come in different sizes for different-sized pools. Most filters measure GPM. A filter’s flow rate should equal or exceed the pump’s GPM output. The number of gallons per minute (GPM) a pool filter can clean indicates its capacity. A pool filter should take 8 hours to clean an empty pool. 50 GPM pool filters can filter 24,000 gallon pools (50 x 60 x 8). 

Pump Compatibility

Without a pump to force water through it, a filter will not function properly. It is essential to confirm that the pump and filter you choose are suitable for use together before purchasing. The pump must have sufficient strength to force water through the filter without being so forceful that it causes harm to the filter.

When choosing a filter, it is important to select a model with a slightly higher flow rate than the pump’s flow rate. It is imperative that you never pick a filter whose flow rate is lower than the pump’s flow rate since this might cause irreparable damage to the filter. It is expected that the pump and filter when working together, will be able to clean the entire contents of the pool in around 8 hours.

Additional Features

Most pool filters come equipped with features that simplify their operation. The pressure gauges determine the system’s effectiveness in extracting water from the pool. The user is provided with the information necessary to determine whether the filter cartridge should be changed (in the case of a cartridge filter) or if the sand or D.E. filter should be backwashed (in the case of a sand or D.E. filter). In most cases, filters come equipped with features that simplify the process of doing routine maintenance. The majority of them feature quick-release knobs, which enable the user to swiftly open the filter’s lid without having to disassemble a great deal of the associated gear. The filter can be winterized, rinsed, and backflushed with the turn of a knob on some models, while others have multiport designs with switches that provide these capabilities.

What Types Of Cartridge Pool Filters Can You Buy?

Cartridge pool filters all do the same thing despite their different shapes and sizes. You can use many cartridge pool filters with in-ground and above-ground models. Pool volume is most important—above-ground cartridge filters clear less water than their in-ground counterparts.

What Size Filter Do You Need?

Determine your filter size before shopping to avoid buying the wrong one. Check your pool pump’s GPH (Gallons Per Hour) capacity. One hundred square feet of cartridge filter for every 10,000 gallons of water. So, a 25,000-gallon pool needs a 250-square-foot filter. Choose properly sized cartridge filters to avoid clogging. If the size is correct, you may not need to clean a cartridge filter all season.

How Often Do You Have To Replace The Filter?

Above-ground cartridge filters must be replaced weekly or every two years. Read the manufacturer’s instructions and consider replacement filters before buying. A cartridge pool filter can last up to two years. Sunscreen, hair treatments, and deodorants reduce the filter’s lifespan to one year.

What type of above-ground pool filter is best?

Above-ground sand filters like the Rx Clear Radiant Cartridge Pool Filter have high flow rates of 20 gallons per minute and valves with six positions to make maintenance simple.

How long does a cartridge pool filter last?

It is recommended that you replace your cartridge filters about every three to five years. If the pressure gauge rises by 8 PSI more frequently than every six months, you may need to change your cartridge filter. This is another sign that it needs to be replaced.

Frequently Asked Questions – (FAQs)

Is a cartridge or a sand filter better?

Only 20 microns can be filtered via a sand filter, whereas 10 microns can be filtered through a cartridge filter. In other words, a cartridge filtration system will be able to remove more dirt and debris from your pool, resulting in a cleaner, more dazzling environment. The days of a foggy pool are over.

Are foam pool filters better than paper filters?

Foam pool filters cost less than paper filters. Foam filters have a lifespan of about two months instead of one to two weeks of paper filters. Foam filters can be restored to service after being cleaned with a garden hose.

Which pool filter system will remove the smallest particles?

D.E. filters, which may trap particles as small as 3 microns in diameter, remove the tiniest particles of the three types of filters.

How do I change the sand in a pool filter?

Draining the tank by opening the drain cap at the bottom of the tank is the first step in replacing the sand in a pool filter. Unscrew the hoses from the filter’s multiport valve. When you’re done cleaning out your pool, you’ll want to tape the top of the pipe shut to prevent any sand from going inside. First, remove the lateral assembly and pipe to clean the tank, then use a garden hose to rinse it. Replace the lateral assembly and pipe with new sand and reinstall the sandbox.

Can I use any pool filter in an above-ground pool?

No. You’ll have to make use of an above-ground filter. Due to the fact that the vast majority of above-ground pool pumps are constructed so that they can carry water up to a level higher than the pump, just a few inground pool pumps are.

How to Buy the Right Pool Filter Cartridges?

You need a filter flow rate at least as high as your pump’s GPM. It’s always better to go with a larger pool filter so it can handle the pump’s power. In general, one square foot of filter area per 10,000 gallons of pool capacity is a good starting point.

Is there a difference in pool filter cartridges?

The amount of microns that various types of pool filters can capture varies. Even though chlorine effectively kills bacteria, it is still necessary to remove the dead bacteria from the water. A faulty filter can cause cloudy water.

How often should I clean my pool filter cartridge?

The frequency of cleaning your pool filter cartridge will depend on how often you use the pool. You can clean it weekly, monthly, or less frequently.
