Outdoor pools offer plenty of excitement and fun, but they are prone to elements that can change the pool’s water. As an above ground or in-pound pool owner, it’s critical for you to take measures to keep your pool water clean throughout the entire year.

It is also imperative for you to know your options and get familiar with pool filter terms. In this article, we will cover several different types of pool filters and how to determine what you need for your particular pool.

Which Type of Pool Filter System Do You Need?

Here are three common types of filter systems for pools. Please keep in mind that each has its pros and cons.

Cartridge Filter

Cartridge Filers have been able to maintain their popularity over the years. They are exceptional because they offer a lower maintenance option that filters down to five to ten microns with ease. The thin cloth-like material in cartridge filters makes it easy for them to filter out debris and harmful particles from your pool water.

The filter area is larger than what you find in sand filters (discussed below). This makes it possible for cartridge filters to work efficiently with less water. Fortunately, cartridge filters are easy to clean. Simply remove it and hose it down with a strong stream of water. This will remove filtered out materials.

A cartridge filter offers the following pros:

  • Simple to take care of
  • Saves energy and water
  • It has a larger filter area
  • Backwashing is not needed for this filter.

Here are the visible cons to using a cartridge filter:

  • It is more expensive (when compared to a sand filter)
  • The filter must be replaced every three years

Sand Filter

Many in-ground pool owners prefer sand filters because they are cheap and easy to take care of. They filter particles with the help of a large bed of sand. Particles are filtered out as small as twenty microns. It’s worth mentioning that larger debris is not capable of traveling through a sand filter, but small particles will pass through it without any difficulty.

How do you clean a sand filter? Backwashing the sand will force the dirt and debris out of the filter. You will also be removing the dirt and debris from the pool area. A sand filter will do well for seven years.

Here are the pros of sand filter:

  • It is inexpensive
  • It filters medium to large debris
  • It will typically last for seven years

Here are the cons you need to take into consideration before going with a sand filter:

  • Needs regular maintenance
  • More pressure is required when sand has an overwhelming amount of debris.

D.E. Filter (Diatomaceous Earth)

The D.E. Filter has a different approach when it comes to filtering debris and dirt from pools. It combines the natural filtering material (Diatomaceous Earth) and a cartridge. Diatomaceous Earth is a harmless organic material that is capable of removing as small as three microns from the water in your pool.

Contrary to popular belief, it’s easy to maintain a D.E. filter. You have to backwash the system and make certain you replace the DE material. The filter must be removed and hosed twice a year.

Here are the pros of going with a D.E. Filter:

  • It is easy to maintain
  • It is ideal for pool owners that prefer a more natural option
  • It has a larger filter area

Here are the cons that you must take into consideration:

  • According to intensive studies, DE provides the clearest pool water
  • You can use a pool skimmer to refill your DE powder
  • It’s a reliable system that can last for several years

Which pool filter should I choose?

This is a very good question. Any pool filter will be suitable for your above ground or in-ground pool. It’s not unusual for professional pool cleaners to recommend cartridge pool filters. They know that cartridge pool filters work extremely well when it comes to removing large debris and small particles. Unlike sand filters, backwashing is not required.

A sand filter may be your best bet if you’re looking for a cheaper system. You must remember that a sand filter will not filter out extremely small particles.

We cannot forget about the DE system. It is your best option if you want to have the clearest water.

A pool filter will help keep your pool water clean throughout the entire year. Using the information above can help you choose a suitable pool filter with ease.
