Keep Your Above Ground Pool Clean with the Right Filter
Looking to maintain crystal-clear water all season long? The right above ground pool filter is essential for removing dirt, debris, and microscopic particles that cloud your water. Whether you're setting up a new pool or upgrading your current system, Doheny’s offers a wide selection of filters designed specifically for above ground pools, each with unique benefits to match your pool size, usage, and maintenance preferences.
Why You Need a Filter Built for Above Ground Pools
Above ground pools typically have smaller water volumes and more exposed surfaces, which means they can accumulate debris and lose water clarity faster than inground pools. A properly sized and matched filter system can:
- Improve water clarity and hygiene
- Reduce chemical usage
- Prevent algae and bacteria buildup
- Extend the life of your pool pump and heater
From compact cartridge systems to powerful sand filters, Doheny’s has the right solution for your setup.
Types of Filters for Above Ground Pools
We carry three main types of filters for above ground pools: sand filters, cartridge filters, and DE (diatomaceous earth) filters. Each offers different levels of filtration and maintenance requirements.
Above Ground Sand Filters
Sand filters are a popular, low-maintenance option for above ground pools. They use specially graded sand to trap particles as small as 20 microns. These systems are easy to operate and require backwashing as needed to flush out debris. Sand typically needs to be replaced every 5–7 years.
Ideal Use Cases: Low maintenance setups, budget-conscious owners

Above Ground Cartridge Filters
Cartridge filters offer finer filtration, down to 5–7 microns, and are ideal for any size pool. They don’t require backwashing; instead, you simply remove and rinse the cartridge with a garden hose. Cartridges typically last 2–3 seasons depending on usage. Above ground cartridge systems work best with a 2-speed pump and motor. Doheny’s suggests you filter your water for 24 hours a day. A 2 speed pump running on low speed allows you to run your filter your water for less than a third of the cost of a normal pump.
Ideal Use Cases: Easy Maintenance/Water Conservation

Above Ground DE Filters (Diatomaceous Earth)
DE filters provide the highest level of filtration—down to 3-5 microns. They use a fine powder made from fossilized plankton to coat internal fingers and grids and trap even the smallest particles. These filters require backwashing and periodic recharging with DE powder.
Ideal Use Cases: Filtering the finest debris, premium performance

Choosing the Right Filter Size
The right filter depends on your pool’s size and pump flow rate. As a general rule:
- Small pools (up to 10,000 gallons): 50–75 sq ft cartridge or 16" sand filter
- Medium pools (10,000–15,000 gallons): 75–100 sq ft cartridge or 19" sand filter
- Large pools (15,000+ gallons): 100+ sq ft cartridge or 22"+ sand filter
