Pool Filters
Sand, cartridge, and DE filter systems.
Keep your pool water sparkling clear and sanitary with our premium selection of high-efficiency pool filters. Your filtration system is the heart of your pool, working constantly to trap fine debris, dust, and organic particles before they can turn into cloudy water or algae. We stock top-rated sand filters, cartridge systems, and diatomaceous earth (DE) filters designed to handle everything from small above ground setups to large custom inground pools.
Choosing the right filter system ensures better water clarity, reduces the need for heavy chemical treatments, and extends the lifespan of your pump. Whether you are replacing an outdated unit or upgrading to a more efficient model, our inventory features durable, weather-resistant designs from the industry’s most trusted brands. Browse our collection below to find a reliable filter solution that matches your pool’s flow rate and volume requirements perfectly.

How to Choose the Right Pool Filter
Selecting the right filter for your pool is about finding the balance between filtration performance and ease of maintenance. Your filter must be sized correctly for your pool’s total water volume and your pump’s flow rate; an undersized filter will work too hard and fail prematurely, while an oversized one can be inefficient. Understanding the three primary filter technologies will help you decide which system best fits your routine.
Primary Filter Technologies
Each filter type uses a different medium to capture contaminants. Your choice depends on how much time you want to spend on maintenance and the level of clarity you demand.
- Sand Filters: These are the most common and lowest maintenance option. They use special pool-grade sand to trap debris as water passes through. Cleaning is easy: you simply turn a valve to backwash the system, which flushes the trapped dirt out through a waste line.
- Cartridge Filters: These systems use replaceable pleated cartridges to catch fine particles. They provide excellent filtration and are very easy to maintain. Because they do not require backwashing, they save water and are perfect for regions with water restrictions.
- DE (Diatomaceous Earth) Filters: These provide the highest level of filtration available, capturing microscopic debris that other filters miss. They use a fine powder that coats internal grids. They require more technical upkeep, but the resulting water quality is the industry standard for crystal clarity.
Sizing, Compatibility, and Flow Rate
Your filter must be able to process your pool’s entire volume of water within a standard cycle. When reviewing product specifications, look for the turnover rate and the square footage of the filter media. If you are upgrading from an older unit, check your existing plumbing size (usually 1.5 or 2 inches) to ensure a smooth, leak-free transition. If you are unsure about your specific needs, compare the filter’s GPM (gallons per minute) rating against your pool pump’s output to ensure they are properly matched.
Maintenance and Buying Considerations
Consider how much hands-on maintenance you prefer. Sand filters are durable and simple to operate for years, while cartridge systems are ideal for those who prefer quick, tool-free filter swaps. If you choose DE, be prepared to add fresh powder back into the system after every backwash cycle. Always check the physical footprint of the filter to ensure it fits comfortably on your equipment pad with enough clearance for easy access to valves and drains.
Pool Filter Technology Comparison
Sand Filters: Low-maintenance, high-durability needs. Simple backwash cleaning process; very long filter life. Cartridge Filters: Water-conscious homes; easy upkeep. Superior filtration efficiency with no backwashing required. DE Filters: Maximum water clarity and purity. Filters microscopic particles for the clearest water possible.
