Sand vs. Cartridge vs. DE: Which Pool Filter is Right for You?
Your Pool Filter is the Heart of Your System—But Which Type is Best?
For pool owners, a crystal-clear pool often comes down to one piece of equipment working hard behind the scenes: the pool filter. This vital component removes debris, dirt, and microscopic particles, keeping your pool water healthy and sparkling.
When it comes time to repair, replace, or install a new system, you face a big question: Should you choose Sand, Cartridge, or Diatomaceous Earth (DE)?
As your local pool service provider, we break down the pros and cons of the three main types to help you decide which is the best fit for your home and maintenance style.
1. Sand Filters: The Classic and Low-Maintenance Choice
Sand filters are the oldest and most common type of pool filter. They use specialized filter sand (usually #20 silica sand) to trap particles.
Best For:
Pool owners who prioritize ease of use, durability, and a low annual maintenance cost. If you're okay with slightly less water clarity than other options, sand is a great reliable workhorse.
2. Cartridge Filters: The Balanced and Water-Saving Choice
Cartridge filters use a pleated fabric cylinder (or multiple cylinders) that traps debris as water passes through. They have become extremely popular for their balance of performance and efficiency.
Best For:
Pool owners in drought-prone areas (like Florida, where water conservation is key) or those who want better water clarity than sand without the high maintenance of a DE system.
3. DE Filters (Diatomaceous Earth): The Maximum Clarity Choice
DE filters use DE powder (skeletal remains of microscopic aquatic organisms) as the filtering agent, achieving the highest clarity of any system.
Best For:
The homeowner who demands perfection in water clarity and is willing to invest more time, maintenance, and attention to get it. Often found on very large or commercial pools.
Choosing Your Next Filter System
If you are replacing an existing unit, we usually recommend sticking with the same type unless you have a strong reason to switch (e.g., switching from DE to Cartridge to avoid high maintenance).
🛑 Ready for an Upgrade or Need a Repair?
Whether your current filter is losing pressure, your pool water is perpetually cloudy, or you're ready to upgrade to a more efficient system, the job requires a certified professional. Improper installation or filter cleaning can lead to costly damage to your pool pump or filter housing.
