On a hot summer day, there’s nothing as relaxing as taking a dip in your very own swimming pool. The joy of seeing a sparkling blue pool and it’s crystal, clear water, the adrenaline rush that comes when you jump into it, the cool waters, and the endless hours spent wading in it – ahhh, the simple pleasures of life!
But, then there are times when your swimming pool presents another story. Murky water that looks too gross to dip your toes into, let alone swim in. Nasty smells that make you want to clip your nose. Dust, dirt and other floating debris can spoil the fun of swimming and relaxation time.
This is where – pool filter cartridges come to your rescue!!! From keeping your swimming pool water free from dead skin cells, saliva, windblown dirt, and debris, there are plenty of things that a pool filter cartridge does.
Even the most casual pool user is aware that pools come with filtering equipment and motors. But, not many are aware of what these devices are, how they work and what do they do exactly. Worry not, here in this article; you can find all that you need to know about pool filters. Whether you’re looking to buy a new one, or just expanding your knowledge base, this article is for you.
Let’s get started.
Pool Filters 101
Pool Filters (or filter systems) are the equipment that make up part of the swimming pool’s plumbing network. You can think of it as a large screen that removes debris and other dirt from your pool using physical barriers. They handle both small debris (some microscopic) as well as bigger contaminants.
Consider your pool filter as the first wall of defense against water contaminants.
Broadly speaking, there are three major types of pool filters like:
- Cartridge filter systems
- Sand filter systems
- DE filter systems
Each of these types of filter systems has its advantages and disadvantages. But when used in the right manner, all three types of filters keep your pool water free from contaminants.
How do Pool Filters Work?
Pool filters work together with the pool’s pumps and motors. The pool pump is the primary component of your pool’s circulation system. It keeps the water in your pool continuously circulating. The pump pulls in water from the pool and sends it to the main drain and the skimmer. Once the water passes through the skimmer, it pumps the water through the filter system.
It is also the pump’s job to push the newly filtered water back out to the pool along the main return channel.
The role of the filter system in the pool’s circulation system is to filter out dirt and debris from the water and return clean water into the system. This filtered water then reaches other parts of the system like a chlorinator, heater (if present) and is directed via an outlet pipe back to the pool.
The process is repeated as long as the system is kept on.
Here’s a step-by-step look at the process:
- The filtration process starts when the pool water is pulled through the strainer basket by the pool pump through the main drain.
- The initial filtering occurs at the “strainer basket.” This removes extra large debris. The strainer basket is usually located under an easily removable cover flush with the pool deck. The strainer basket removes large debris, such as leaves, sticks and bugs.
- This pre-filtered water then reaches the main pool filters for the smaller debris filtering process. Any leftover debris that was not removed by the strainer basket and other water contaminants are now removed from the system.
- The clean water (now free of debris) then next reaches the heater (if used) to alter the temperature according to your specifications and then the chlorinator (to kill microorganisms).
- After this, the fully filtered, clean water is pumped back into the pool.
So What Do Pool Filters?
A pool without a filter is pretty much a dirty pit of water. A filter not only removes dirt and other large debris but also clears your water of other contaminants.
Here’s what the filter removes from the water:
- Floating debris – Be it leaves, branches, bugs, or any other floating debris, your filter removes it from the water.
- Dirt that isn’t visible to the naked eye – This includes sweat, saliva, oils, pathogens, bacteria other micro-organisms and contaminants, and food particles.
- The pool filter helps to prevent the growth of algae and other bacteria as well.
Swimming in a pool of unclean water is not only gross but can severely affect your health. Dirty pool water can lead to recreation water illnesses like diarrhea, ear infections, even eye, skin, respiratory, neurologic and other gastrointestinal illnesses.
Here are a few other Cleaning Hacks for Crystal Clear water in your Pool
Drop a few tennis balls in your pool. The ball attracts oils, suntan lotions, hair and makeup product traces left behind by swimmers.
Spray a couple of dryer sheets with lemongrass or other insect repellants and place these sheets around your pool, to ward of mosquitoes and other bugs. Citronella candles work great too!
Your pool filter doesn’t just help to avoid stains and smells in your pool, thereby keeping your water sparkling clean, but in fact, plays an indispensable role in ensuring that you stay safe while taking a dip in your pool by providing healthy water.
If you still find your water is not 100% clean even with your filtering system on, it means that it’s time for a pool filter cartridge replacement. Make sure to check with your pool filter vendor to find replacement filter cartridges and keep your filter in perfect working condition.
Above all, Pool Filters
- Keep you Safe
- Keep your pool working perfectly
- May be required by law in some states
So, make sure that you choose the right pool filter, and with proper maintenance, your pool will become the most happening place in the neighborhood.
