Filter options

16/04/2025

When you imagine your dream pool, you probably see clean, sparkling water. That’s only possible with a good filtration system. Your pool filter works together with your pump to remove dirt, debris, oils, and tiny particles from the water, keeping it clear and safe to swim in.

But not all filters are the same. Let’s look at the most common types and help you choose what’s right for your pool.

Sand filters: the classic choice

How it works: Water flows through a tank filled with special filter sand that traps dirt and particles.
Best for: Pool owners looking for a reliable, budget-friendly option with minimal fuss.

Pros:

Affordable and widely available
Low maintenance
Ideal for larger pools

Cons:

Filters only down to about 50 microns
Requires regular backwashing (uses water)

Cartridge filters: clarity with less water waste

How it works: Water passes through a paper-like cartridge that catches debris.
Best for: Smaller to medium-sized pools, or areas with water restrictions.

Pros:

Filters down to 10–20 microns for better water clarity
No backwashing, which saves water
Compact and easy to install

Cons:

Cartridges need to be cleaned manually
Replacements needed every 1–2 seasons

Glass media: the smart upgrade for sand filters

How it works: Recycled glass grains in a sand filter trap finer particles—even oils and bacteria.
Best for: Pool owners who want top performance, long-term savings, and more eco-friendly options.

Pros:

Filters down to 5 microns—super clear water
Less backwashing and water use
Lasts longer than sand (up to 10 years)

Cons:

Higher upfront cost
Needs the right setup and proper filling

What filter to choose?

Go with sand if you want a simple and cost-effective setup.
Choose cartridge if you value water efficiency and don’t mind a bit of hands-on cleaning.
Upgrade to glass if you want the cleanest water, less maintenance, and can invest a little more upfront.

No matter what you choose, good filtration is essential to enjoying a healthy, beautiful pool.
