Hayward in ground pool filters are at the top of the class when it comes to removing debris and gunk from your in ground swimming pool. In The Swim has many types of Hayward in ground pool filters to choose from at a range of prices to fit your needs and budget. Hayward D.E. pool filters (or Diatomaceous Earth) remove the smallest particles, including dust and pollen, from your pool’s water, making this type of filter twice as efficient as sand pool filters. Hayward sand pool filters are a favorite among pool owners thanks to how well they clean pool water and how easy they are to operate and maintain. Sand filters are very efficient at flowing pool water, and they are constructed to be highly durable and to last for years. Hayward cartridge pool filters tend to be the least expensive and the most popular because of price, ease of use and simple operation. A cartridge filter uses an interior, removable filter that catches debris as it circulates through the filter housing. The cartridge can be taken out and cleaned with a garden hose. No need to backwash, which saves thousands of gallons in an average season.
