Which Filter Cartridge Brand is Best?
Pleatco and Unicel made nearly all cartridge pool filters before other brands came into the market.
Their pleated design cartridges were mainly used in oil and gas filters in the late ’60s and only hit the peak in the early ’70s.
Most OEM cartridge filters came from Meissner Manufacturing Company, which designed a pleated filtration system from Reemay polyester.
It was original manufactured for the apparel industry or sector by DuPont.
Dick Meissner then decided to supply pool dealers with a more affordable filter. That is when the Unicel brand was created.
But Which Cartridge Filter Brand is Best?
Reemay has been the standard of every cartridge pool filter since the ’60s. It performs in all conditions, including a saltwater pool.
The Pleatco material is still under review but is a viable option to the Reemay.
What is Your Pool Condition?
One thing to note is your pool’s condition when deciding whether to go for the Reemay or Pleatco fabric cartridge pool filter.
That is because one might work for the saltwater system, filthy pool, or other conditions better than the other.
You might find one model fitting better, loading more evenly, or offering longer filter cycles
Different Options of the Same Cartridge
And you also need to note that there are two or more cartridges available for different pool filter types.
That means you find a version with the typical area and another with more pleats to add more filter area or square feet into the cartridge’s dimensions or size.
Besides the two brands, you get Aladdin and Filbur cartridge filters.
The Filbur mainly provide spa cartridge while the Aladdin makes the Reemay types of filters.
Are OEM Cartridge Filters Better?
Today most replacement filter cartridges are made to the manufacturer’s specifications in construction, weight, and size.
And the vital thing to note is most filter manufacturers do not produce their cartridge filters.
They place a massive order with the significant fabricators or brands, and you can be sure of getting quality products.
However, there are manufactures like Sta-Rite and Jacuzzi who make patented filter pool cartridges.
Which Cartridges Filters Brands to Avoid?
There are generic cartridges for in-ground and above-ground pools that have hit the market in the past ten years.
You might find them on dubious internet sites and are made of low-quality material, substandard construction, and are cheaply priced.
Which Models to Purchase?
Avoid the above models and go for 4oz polyester material, solid internal core, and heavy end caps and bands cartridges.
Stick with the major manufacturers like Intex, POOLPURE, SunSet, among others.
They make high-end caps models and are found on reputable websites like Amazon.
What to Consider When Buying a Cartridge Pool Filter
The market has different cartridge pool filters of different sizes and shapes, but all do more-or-less of the same work.
The two main versions are one made for above-ground and in-ground pools, although most work for either pool like Hayward XStream CC1000.
The significant thing here is the water volume (size) of the pool. An above-ground pool filter is more diminutive and cleans a small volume of water.
So, ensure you consider the following things when buying your cartridge pool filter.
- The Size of the Pool Filter
The pool filter size applies whether you are buying a cartridge filter, a sand filter, or a diatomaceous earth filter (DE filter).
You can avoid buying the incorrect model when you figure out the perfect filter size.
Check the pool pump GPH or flow rate to make sure it can accommodate the filter.
The standard gauge for the cartridge filter is 100 square feet for every 10K gallons of water.
For instance, you need a 250 square feet cartridge filter for 25,000-gallon pools.
Some Tips: Cartridge filters, D.E filters, and sand filters do not clog quickly when sized correctly.
- The Size of Impurities
Cartridge cleaners are better at trapping tiny materials than sand filters, although they do not match the D.E models.
The cartridge models are rated according to the microns they trap. A lower number means the filter can do a great job when cleaning the water.
A cartridge filter that collects materials of about 15 microns is ideal for most people.
The cartridge filters generally provide a ranting of 10-20 microns.
A sand filter has a 20-40 microns rating, while the D.E one has a 1-6 microns rating.
- Replacement Frequency
Some cartridge models should replace at least once in two weeks, while others provide service for over 12 months.
Please read the manufacturer’s instructions when buying your pool filter, whether it is the cartridge, D.E, or sand filter.
Some of the best models of cartridge filters can even last for 24-month.
That depends on the materials they clean because hair products, deodorants, and sunscreen shortness their life.
Pro Tip: The best way to prolong your cartridge, D.E, and sand pool filters is to have the swimmer shower or rinse before they jump into the pools.
- Your Budget
You might have found the perfect cartridge for your saltwater system, pool chemical, or other conditions.
But you cannot purchase that model if you do not have the money.
It will not matter whether you want to use the products we have reviewed or other models like Hayward Xstream or Hayward SwimClear Plus Cartridge Pool Filter.
Always set the budget before you go shopping and get the filter within the set budget.
When to Replace a Filter Cartridge
Most pool owners replace their swimming facility cartridges within 3-5 years.
These models are often more expensive than the sand filter ones.
But do not be like other people who use their systems for a limited time. Follow the tricks below to get the most value from the best cartridge for your pool.
- Cleaning Frequency
You need to change the filter cartridge if the cleaning frequency is half of what it used to be at the beginning.
- Water Quality
You should change the filtration cartridge if the water remains green or cloudy despite proper pool chemical balance.
- Cartridge Damage
Look for tears and rips in the material to reduce the water flow rates or lead to insufficient filtering.
- Cartridge Size
A cartridge filter with a more extensive square feet area will not work as hard as a small model.
As for the filters, you should follow the manufacturer’s guide, which can vary from under 2-week to over 12-month.
How Does a Pool Cartridge Filter Work?
Pool cartridges are made up of filter tanks with cartridges inside—the cartridges house membranes.
The water gets pumped to the filter tanks and passes via the filter.
Everything from debris to particles gets trapped by the filter, leaving clear and clean water.
You then clean the filter cartridge when the pressure gets to 8-10 PSI by rinsing it with water.
That saves you water and energy as you do not backwash them like the D.E filters.
The water filter cartridge also needs replacement – follow the tips above.
It is vital to keep your above-ground or in-ground pool clean if you want to enjoy its water.
The ideal way to achieve that is to get the best pool filter cartridge and pool filter that matches your swimming pool filtration needs.
