When choosing a filter, whether it be Sand, D.E. or Cartridge, you’ll have to decide on the right size pool pump for your pool. Filter size is important and something you’ll want to consider to avoid potential problems in the future.
A good rule to remember is bigger, in this case, is better. Although larger filters come with a bigger price tag, they provide better filtering and easier maintenance for pool owners.
Benefits of larger filters:
- Increased time between cleaning and backwashing
- Increased filtration of small particles
- Increased longevity of filter media
So when it comes to choosing a filter size, 1st determine the gallons per minute your pump is currently distributing. Then, determine the filter size that makes the most sense to you. If your budget is tight, you may want to go with a filter that has a flow rate just above the GPM (gallons per minute) rating. However, if you have a bigger budget, a larger pool filter will give you better water with less maintenance.
