DE Filter vs Cartridge Filter vs Sand Filter: Which is Right for You?
When it comes to choosing a pool filter, there are three main options: DE filters, cartridge filters, and sand filters. Each type of filter has its own advantages and disadvantages, so it’s important to choose the one that’s right for your needs.
DE Filters
DE filters use a fine powder called diatomaceous earth (DE) to filter out impurities from pool water. DE is a natural substance that’s made up of the fossilized remains of diatoms, a type of algae. DE is very effective at filtering out small particles, such as dirt, pollen, and algae spores.
Benefits of DE Filters
- DE filters can remove very small particles from pool water.
- DE filters are very effective at preventing algae growth.
- DE filters can last for many years if they’re properly maintained.
Disadvantages of DE Filters
- DE filters require more maintenance than other types of filters.
- DE filters can be more expensive to purchase and operate than other types of filters.
- DE can be messy to work with.
Cartridge Filters
Cartridge filters use a series of cartridges to filter out impurities from pool water. Cartridges are made of a variety of materials, including cellulose, polyester, and fiberglass. Cartridge filters are very effective at filtering out small particles, such as dirt, pollen, and algae spores.
Benefits of Cartridge Filters
- Cartridge filters are easy to maintain.
- Cartridge filters are relatively inexpensive to purchase and operate.
- Cartridge filters are available in a variety of sizes to fit different pool sizes.
Disadvantages of Cartridge Filters
- Cartridge filters can’t remove very small particles from pool water.
- Cartridge filters can’t prevent algae growth as effectively as DE filters.
- Cartridge filters need to be replaced more often than DE filters.
Sand Filters
Sand filters use a bed of sand to filter out impurities from pool water. Sand filters are very effective at filtering out large particles, such as dirt, leaves, and bugs. However, sand filters are not as effective at filtering out small particles, such as dirt, pollen, and algae spores.
Benefits of Sand Filters
- Sand filters are very affordable to purchase and operate.
- Sand filters are easy to maintain.
- Sand filters are available in a variety of sizes to fit different pool sizes.
Disadvantages of Sand Filters
- Sand filters can’t remove very small particles from pool water.
- Sand filters can’t prevent algae growth as effectively as DE filters.
- Sand filters need to be backwashed more often than DE filters.
Choosing the Right Filter for You
The best way to choose the right filter for you is to consider your needs and budget. If you want a filter that can remove very small particles and prevent algae growth, then a DE filter is the best option. If you’re on a budget and don’t mind replacing cartridges more often, then a cartridge filter is a good choice. If you’re looking for an affordable and easy-to-maintain filter, then a sand filter is a good option.
No matter what type of filter you choose, it’s important to properly maintain it to keep your pool water clean and clear.
