SAND FILTERS: How They Work & What to Know

What is a Sand Filter?
A sand filter is a tank filled with special filter sand and powered by a pump. Here's how it works:

Water from the pool is pulled into the tank.
As water passes through the sand, dirt and debris are trapped in the sand bed.
Clean water is then pushed back into the pool.

Key Benefits:

Effective filtration of larger debris
Simple to operate and maintain
Cost-efficient—sand filters are typically affordable
Durable—filter sand can last several years before needing replacement

Things to Keep in Mind:

Backwashing is required to clean the filter:
- This process flushes out the trapped dirt and debris.
- You'll need a waste hose or a nearby area where dirty water can be discharged.
- Backwashing can lower your pool’s water level, so you may need to top off the pool more often.
Tank size matters – the tank holds several gallons of sand, depending on the filter model.
Higher GPH (gallons per hour) = better water circulation and faster filtering.

CARTRIDGE FILTERS: What You Need to Know

How Cartridge Filters Work:
These filters use a round, pleated paper cartridge to trap dirt and debris. As water flows through the cartridge, debris is captured, and clean water returns to the pool.

Key Features:

Reusable Cartridges
Cartridges can be cleaned and reused for a limited time. Most last around 2 weeks, depending on water quality and usage.
Lower GPH (Gallons Per Hour)
Cartridge filters tend to have slower water flow than sand filters. Water must work harder to pass through the folds, which can reduce overall circulation.
Alphabetical Sizing
Cartridges come in lettered sizes—A, B, C, etc.
Brand doesn't matter as long as the size matches your pump’s requirement.
