A Complete Guide to Different Types of Pool Filters

When it comes to maintaining a pristine swimming pool in Arizona, choosing the right pool filter is crucial. The dry climate, dust storms, and scorching temperatures can make pool care more challenging for homeowners. At FTG Pools, we aim to help you understand the various pool filter options to make the best choice for your needs. Here’s a comprehensive guide to the three main types of pool filters: cartridge, sand, and diatomaceous earth (D.E.).

Cartridge Pool Filters

How They Work: Cartridge pool filters use a cylindrical filter cartridge made of pleated polyester or paper. Pool water passes through the cartridge, trapping debris and contaminants within the pleats.

Benefits:

• Easy Maintenance: Cartridge filters are straightforward to clean. Simply remove the cartridge and rinse it with a garden hose.
• Higher Flow Rate: These filters allow water to pass through more quickly, which can mean better circulation.
• Energy Efficiency: The higher flow rate can lead to less strain on the pool pump, saving energy over time.

Drawbacks:

• Frequent Cleaning: Depending on usage, cartridge filters may need cleaning every 2-4 weeks.
• Replacement Costs: Cartridges can wear out and need replacing every 2-3 years.

Best For: Residential pools of various sizes, particularly those that value ease of maintenance and energy efficiency. For tips on keeping your pool in top condition, check out our pool cleaning tips for Phoenix homeowners.

Sand Pool Filters

How They Work: Sand filters use specially graded sand to filter out debris. Water is pushed through the sand bed, which traps contaminants. Clean water is then returned to the pool.

Benefits:

• Simple Operation: Sand filters are known for their simplicity and reliability.
• Durability: With proper maintenance, a sand filter can last up to 7 years before the sand needs replacement.
• Lower Initial Cost: These filters are often more affordable to purchase than other types.

Drawbacks:

• Less Effective for Fine Particles: Sand filters may not capture the smallest particles, resulting in slightly less clarity compared to cartridge or D.E. filters.
• Regular Backwashing: To maintain efficiency, sand filters require backwashing—reversing the water flow to clean the filter—every 1-2 weeks, which uses water.

Best For: Large pools or those seeking a low-maintenance, long-lasting solution without the need for frequent cleanings. If you're facing issues with filter performance, see our top 5 pool repair issues and how to prevent them for troubleshooting advice.

Diatomaceous Earth (D.E.) Pool Filters

How They Work: D.E. filters use a fine, white powder made from fossilized diatoms. This powder coats a grid within the filter and captures microscopic particles as water flows through.

Benefits:

• Superior Filtration: D.E. filters can trap particles as small as 2-5 microns, providing crystal-clear water.
• Efficient Operation: These filters are highly effective, making them ideal for homeowners who want top-tier water clarity.
• Long Lifespan: With good care, D.E. filters can last many years.

Drawbacks:

• Complex Maintenance: Maintaining a D.E. filter can be more involved. Recoating the filter with D.E. powder after each backwash is necessary.
• Higher Cost: D.E. filters are generally more expensive to buy and maintain compared to sand and cartridge filters.
• Environmental Concerns: Disposal of used D.E. powder should be handled carefully due to its fine, abrasive nature.

Best For: Pool owners who prioritize water clarity and are willing to put in extra effort for maintenance. If you're unsure about when to call for expert help, refer to our Signs Your Pool Needs a Repair: When to Call a Professional.

How to Choose the Right Pool Filter for Your Arizona Pool

Factors to Consider:

• Pool Size: Larger pools may benefit from the robust capacity of sand filters, while smaller pools could find cartridge filters more economical.
• Maintenance Preferences: If you prefer minimal maintenance, a sand filter might be ideal. For homeowners willing to invest time in cleaning for the best water quality, D.E. filters are the top choice.
• Budget: Initial costs, replacement parts, and ongoing maintenance should all be factored into your decision.

Maintaining Your Pool Filter

No matter which type of filter you choose, proper maintenance is key. Regularly clean or backwash your filter based on the manufacturer’s recommendations to prevent clogs and ensure optimal performance. Check your skimmer and pump baskets frequently to remove debris.
