Understanding The Different Types of Filters for Your Swimming Pool

In our previous posts, we've discussed the importance of skimmer baskets and vacuuming in maintaining a sparkling clean pool. However, another key component that plays a pivotal role in your pool's cleanliness is the pool filter. With various types of pool filters available, choosing the right one for your pool can seem like a daunting task. But worry not! Our guide below will help you understand the different types of filters for your swimming pool, listing out the pros and cons of each.

Got a Pool Problem? We Can Help.


1. Sand Filters

A sand filter is one of the most common types of pool filters and is often the go-to choice for residential pool owners.


  • Easy to Use: Sand filters

  • are simple in design and easy to operate, making them ideal for first-time pool owners.

  • Low Maintenance: They only require backwashing (reversing the flow of water to remove trapped debris) every few weeks or when the pressure gauge rises 8-10 PSI from its clean reading.

  • Cost-Effective: Sand filters are usually less expensive upfront and the sand needs replacement only every five to seven years.


  • Lower Filtration Capability: Sand filters have a higher micron rating (20-100 microns), meaning they may not filter out smaller particles as effectively as other types.

  • Increased Water Usage: The backwashing process can consume a significant amount of water.

2. Cartridge Filters

Cartridge filters consist of a removable cartridge that traps debris. They have become increasingly popular due to their efficiency and eco-friendliness.


  • Efficient Filtration: Cartridge filters can filter out particles as small as 10-20 microns, providing superior water clarity.

  • Water Conservation: They don't require backwashing, which means less water is used compared to sand filters.

  • Easy Maintenance: Cleaning involves simply removing the cartridge and hosing it off.


  • Frequent Cleaning: Depending on your pool's usage and debris load, cartridge filters might require more frequent cleaning.

  • Higher Initial Cost: Cartridge filters tend to be more expensive upfront, and replacement cartridges can also be pricey.

3. Diatomaceous Earth (D.E.) Filters

Diatomaceous Earth filters use a natural powder made from fossilized remains of diatoms (a type of hard-shelled algae) to filter out debris.


  • Superior Filtration: D.E. filters provide the finest level of filtration, able to filter out particles as small as 1-3 microns, ensuring crystal-clear water.

  • Longer Cleaning Cycle: Compared to sand and cartridge filters, D.E. filters usually require less frequent cleaning.


  • Higher Maintenance: D.E. filters require backwashing and refilling the D.E. powder, which can be more labor-intensive.

  • Costly: They are often the most expensive type of pool filter upfront, and the cost of D.E. powder can add up over time.

  • Environmental Concerns: Used D.E. powder must be disposed of properly, as it can be harmful to the environment.
