There are three main types of pool filters available, sand, diatomaceous earth (DE) and cartridge, each one offering pros and cons. Determining which filter is best for your pool will depend on how much you use your pool, municipal codes in your area and your personal preferences. Knowing the differences can help you make the best choice for your pool.
Sand Filters
Sand filters clean your pool water by using a combination of pea gravel and sand to filter out contaminants.
- Pros: Sand filters do not require annual maintenance, and only need the media replaced about every six years in most home pools. Media replacement in sand filters is generally affordable, they backwash easily and rarely require repairs.
- Cons: The biggest drawback of sand filters is that they provide poor filtration in comparison to other options, and need to be cleaned every week.
DE Filters
DE filters use diatomaceous earth to coat the interior of the filter, cleaning the water as it flows through it.
- Pros: DE filters provide excellent filtration. They only need to be cleaned about every 4-8 weeks, and do not require a water clarifier.
- Cons: Not all municipalities allow DE filters. In addition, repairs can be expensive.
Cartridge Filters
Cartridge filters use a pleated filter, similar to filters used in air purifiers. These are typically used for smaller pools or spas.
- Pros: Cartridge filters are easy to clean and maintain.
- Cons: Replacing cartridge filters can be very expensive, and cleaning the filters can be more difficult than other types.
Talk with your pool professional to determine which filter is best for your pool, and build an oasis that’s as clean and clear as it is refreshing.
