July 23, 20256 min read

Is your pool looking a little less sparkling these days? Living in a sunny spot like Apache Junction, where swimming pools are practically a backyard essential, keeping your pool in top condition is a high priority. But no matter how much you skim the surface or balance the chemicals, an underperforming pool filter can ruin your efforts and leave your water murky. 

A clean, healthy pool begins with a properly functioning filter, yet so many homeowners overlook this vital piece of equipment. Regular cleaning isn’t just about appearances—it’s about extending the life of your pool, saving money, and swimming in clear, pristine water. Stick around as we walk you through common pool filter problems and how regular cleaning can keep these issues at bay.

Why Do Pool Filters Need Cleaning? 

Pool filters are like the lungs of your pool, diligently working to trap dirt, debris, and everything else that doesn’t belong in that refreshing oasis. But when filters get clogged or dirty, their performance takes a nosedive. This doesn’t just hurt your pool’s cleanliness; it can lead to bigger issues like damaged pumps, increased energy bills, and even health risks. 

Here in Apache Junction, the desert environment adds extra challenges. Gusty winds bring in fine dust and other debris that settle in your pool, and with fierce sun exposure, algae can quickly become an issue. The good news? Preventing these problems is easier than you might think, and it starts with one simple solution—regular filter cleaning. 

Common Pool Filter Issues 

Pool filters, though durable, can face several common problems. Here’s a closer look at what might be impacting your pool’s performance. 

1. Clogged Filters 

When your filter collects too much dirt, dust, and oils, it becomes clogged. A clogged filter restricts water flow, leading to poor filtration and putting unnecessary strain on your pool’s entire circulation system. 

How Cleaning Helps 

By removing accumulated debris, you restore water flow and ensure your filter can capture new contaminants efficiently. 

2. Pressure Problems 

A pool filter should operate within a specific pressure range. When the pressure is too high or low, it’s often a sign of trouble. High pressure usually indicates a dirty or clogged filter, while low pressure might signal an air leak or restriction in water flow. 

How Cleaning Helps 

Routinely maintaining your filter keeps the pressure within an optimal range, preventing damage to the pump and other equipment. 

3. Algae Growth 

You might think algae is just a chemical imbalance issue, but filters can play a role too. A dirty filter is less effective at catching algae spores, giving them the perfect opportunity to proliferate. 

How Cleaning Helps 

A clean filter traps algae spores more effectively, working alongside proper chlorine levels to keep your pool water crystal clear. 

4. Short Filter Lifespan 

Filters aren’t cheap, and replacing them too frequently can really add up. When neglected, dirt and grime cause filters to wear out faster than they should. 

How Cleaning Helps 

Regular cleaning extends the lifespan of your filters, saving you money in replacement costs over time. 

5. Cloudy Water 

If your pool water appears cloudy, your filter may not be doing its job properly. This can happen when oils, sunscreen, and dirt saturate the filter media. 

How Cleaning Helps 

Routine cleaning removes these contaminants, ensuring your pool water remains sparkling and inviting. 

Types of Pool Filters and Their Cleaning Needs 

Not all pool filters are the same, and cleaning methods vary depending on the type you have. Here's a quick breakdown. 

1. Cartridge Filters 

Cartridge filters use pleated material to trap debris. They’re popular for being low-maintenance and energy-efficient but require periodic rinsing and occasional deep cleaning. 

Cleaning Tips for Cartridge Filters 

  • Remove the filter and rinse it with a garden hose to clear surface debris. 

  • Once or twice a year, soak the filter overnight in a cleaning solution to remove oils and minerals. 

2. Sand Filters 

Sand filters use a bed of sand to catch particles. Backwashing (reversing water flow) cleans the sand, though it still needs replacement every 3–5 years. 

Cleaning Tips for Sand Filters 

  • Backwash regularly to maintain performance. 

  • Use filter cleaner annually to remove buildup that backwashing misses. 

3. DE Filters 

DE (diatomaceous earth) filters provide the finest filtration, but they require frequent backwashing and replenishing of DE powder. 

Cleaning Tips for DE Filters 

  • Backwash when pressure rises significantly above normal. 

  • Disassemble and deep clean the grids annually to ensure efficiency. 

How Regular Filter Cleaning Benefits Apache Junction Homeowners 

Here in Apache Junction, you face unique challenges like intense heat, dusty winds, and sporadic rain. Filters get clogged faster with our environmental conditions, making cleaning all the more essential. By staying on top of maintenance, you ensure your pool can weather the elements and remain a relaxing retreat for your family. 

Saving Energy 

A dirty filter makes your pump work harder, leading to higher energy bills. Keeping your filter clean ensures smooth operation and reduced energy costs. 

Boosting Lifespan 

Both your pool equipment and filter benefit from routine cleaning. Neglect leads to wear and tear, while maintenance extends their usability. 

Improved Health 

Dirty filters harbor bacteria, which can cause skin irritation and other health issues. Regular cleaning eliminates these risks, giving your family peace of mind.

Pool Filter Cleaning - FAQs

Q. How do I know if my pool filter needs cleaning? 

A. Common signs include reduced water flow, cloudy water, or if the pressure gauge on your filter rises 8–10 PSI above the normal reading.

Q. What type of pool filter is best? 

A. It depends on your needs. Cartridge filters are low maintenance and great for small to medium pools. Sand filters are durable and cost-effective for larger pools. DE filters provide the best filtration but require more upkeep.

Q. Can I run my pool without a filter? 

A. Running your pool without a filter is not recommended, as it will quickly result in dirty, unhygienic water and increase the likelihood of algae growth.

Q. How long should I run my pool filter daily? 

A. Ideally, your pool filter should run 8–12 hours a day to ensure proper water circulation and filtration. This can vary based on pool size, usage, and climate.
