How to Choose Polyethylene Pool Sand Filters

Choosing the right polyethylene pool sand filter isn't as easy as it seems. There are a lot of factors to consider before making this decision. Here are some key points to consider when purchasing a sand filter for a swimming pool.

• Determine the Pool Size: One of the first things to consider when choosing a sand filter is the size of the pool. The size of the pool will go a long way in determining the type and size of the filter to purchase. Larger pools will require larger filters, while smaller pools will require smaller filters. Choosing the right size filter will help ensure that the pool remains clean and free of debris all year round.
• Consider the Filter's Flow Rate: The flow rate of a sand filter is the amount of water that passes through the filter in a given time. It is usually measured in gallons per minute (GPM). The flow rate is directly proportional to the size of the filter and the size of the pool. The larger the pool, the higher the flow rate will be. It is important to choose a filter with the right flow rate to match the size of the pool.
• Check the Filter's Replacement Sand Requirements: Another thing to consider when choosing a sand filter is the replacement sand requirement. All sand filters will require sand replacement at a given time. Some filters will require more frequent sand replacement than others. It is important to choose a filter with reasonable sand replacement requirements to avoid unnecessary expenses.
• Look for Additional Features: When choosing a sand filter, it is important to look for additional features. Some filters come with additional features, such as pressure gauges, sight glasses, and automatic backwashing systems. These features can help make filter maintenance easier and more effective. It is important to choose a filter with features that will help maintain pool water cleanliness.
