Pool Filtration systems that use cartridge filters are increasingly becoming the popular choice when compared to sand, glass, and DE filtration systems. In today’s article, we list the benefits of cartridge based filtration systems and provide some cleaning advice to make them even more efficient.
The Advantages of Cartridge Filters
One of the primary reasons pool owners swear by cartridge filtration systems is that they save water when compared to other systems. Cartridge filtration systems do not require backwashing to clean them (and in fact, you cannot backwash these systems at all). Pool owners agree that backwashing is a complete waste of water and in fact, there are many municipalities that have made backwashing systems illegal due to the water waste. Filtration systems that use cartridges are water efficient, and not only conserve water, but save money on the water bill!
Compact and Energy-Efficient
Filtration systems that use Pool Filter Cartridges occupy less space than other systems. This makes them an excellent choice for homes that do not have a lot of space to spare for their system. There are also various tank sizes for systems that house larger cartridges, which will reduce the frequency of cleaning
Since cartridge filtration systems do not require backwashing, there is no need to install a separate backwashing water line. Cartridge filtration systems also operate at lower flow rates, saving energy but increasing efficiency. Cartridge filtrations systems can be operated with smaller pumps, reducing energy consumption and the energy bill!
Cartridge filtration systems are easy to maintain and clean. Typically, cartridge filters are cleaned once a month and that is a quick and easy process.
Cartridge filtration systems are easy to install due to less plumbing requirements. The entire process takes just a few hours.
Filtration as Low as 5 – 10 Microns
Most cartridge filters will filter particles of 30 microns or larger. However, there are cartridge filters that can filter particles as small as 5 microns!
The large surface area of a cartridge filter allows it to filter out more dirt particles than sand, glass, or diatomaceous earth filters in less time. And no backwashing like the other systems require.
Other Important Tidbits
What do You Look for in a Cartridge Filter?
Is it from a trusted manufacturer?
Is it easy to find replacements? All cartridge filters must be replaced in time.With the many various brands out there, it can be difficult to find a replacement. Unicel pool filter cartridge replacement are easy to find, and it is very common to use their model numbers as a cross-reference to model numbers of other manufacturers.
Is it made well? Cartridges with sharp pleats filter better and last longer than those with rounded pleats. The smaller gaps prevent dirt from being trapped in the depths of the pool housing. This also makes it easier to clean.
Is it the right size? The correct filter cartridge will fit snugly in the housing of the filter system or skimmer box of a spa. A cartridge that is too small will either not filter properly due to excess water flowing over instead of through the cartridge, and a filter that is too large will not allow you to properly close and seal the housing or skimmer box.
How Do You Clean a Filter Cartridge?
- Remove the cartridge from the housing or skimmer box.
- Using a garden hose (preferably with a jet spray attachment), clean the filter from top to bottom (especially in between the pleats).
- Soak the cartridge in a cleansing solution specifically for filter cartridges for at least an hour (preferably overnight).
- Clean the filter again with a garden hose to remove traces of cleaning solution and any remaining oils or particles.
- Cartridge filters work at optimum performance and efficiency if they are completely dried after cleaning. This allows the woven material to “shrink” back to its original form and filtering capacity. It’s good advice to have a spare (or spares) on hand; this way you can just rotate the cartridges out and reduce downtime of your pool!
How Often Should I Clean the Cartridge?
There is no 100% correct answer to this question. It depends on usage of the pool, the weather, and the environment. A pool being used every day during the summer with lots of foliage will require cleaning more often than in the winter when it is used less and there aren’t a lot of leaves, bugs, or dirt around. However, there is a general rule of thumb and that is to clean it at least once a month during the summer, and about every 6 weeks or so during the winter. Regular cleaning of the cartridge will extend the life of your cartridge. Most cartridges can last between 1-2 years with regular cleanings.
How Long Do Cartridges Last?
Again, this depends upon usage, weather, the environment, and most importantly, maintenance. Regular cleaning will extend the life of the cartridge; but all cartridges will eventually need to be replaced. Larger cartridges (with larger surface area) will last longer than a smaller cartridge. Additionally, pool filter cartridges usually last longer than spa filter cartridges. Keep in mind that microscopic dirt particles will get trapped in the material, and no amount of cleaning will remove them. Eventually your cartridge is going to lose its effectiveness.
An Excellent Choice
When deciding what type of filtration system to use, cartridge filters are ultimately the best choice. Easy to maintain, inexpensive, long-lasting, energy efficient, and no water waste are some of the reasons why both pool veterans and first-time owners make this their choice for filtration needs.
