Pool Filter Balls

Pool filter balls are a new and innovative product designed to replace traditional pool filter media such as sand or diatomaceous earth. They are made of synthetic materials such as polyethylene which lends themselves to being both reusable and recyclable. Since they are incredibly lightweight especially when comparing them to heavy sand, it means they are a lot easier to handle during installation and maintainance.

Eco-friendly filter balls can be used in most types of salt water pool filters and can filter particulate down to as small as 5 microns. This means that they can achieve DE quality filtration without the cost and maintenance required for a high priced DE pool filter. They are an effective and eco-friendly alternative to traditional pool filter media and we'll go over some of the advantages and disadvantages below. 

What are Pool Filter Balls?

Pool filter balls are small, lightweight synthetic balls about the size of ping-pong balls with a rough texture. They have a high surface area, which allows for improved filtration. The balls work by trapping and filtering out dirt, debris, and other particles as the water passes through them in the pool system. They are easy to install and can be used as a replacement for sand in most sand pool filters. One key benefit is they are reusable and can be machine washed in a regular household washing machine inside a laundry bag.

Benefits of Pool Filter Balls

The benefits of filter media balls are quite astonishing when you consider they are simply 100% polyethylene balls. The simple design lends them to being easy to use and a lot less hassle than typical silica sand. When you consider that 3 pounds of reusable filter balls will do the same, and likely better, job at keeping your pool water clean than 100 pounds of sand it really seems like a great option for most pool owners. The following are some of the benefits you can expect from polyethylene filter balls:

  1. Superior filtration: They have a higher filtration efficiency than traditional filter media such as sand or diatomaceous earth. They can filter particles as small as 3 microns, resulting in cleaner and clearer pool water.
  2. Longer lifespan: They can last up to 2-3 years before needing to be replaced, compared to sand or diatomaceous earth which typically needs to be replaced annually. This can save you time and money in the long run.
  3. Reusability and eco-friendliness: Filter balls are made of washable materials and can be recycled again after use. This makes them an environmentally-friendly option compared to traditional sand media.
  4. Easy to install and maintain: Pool filter balls are easy to install and can be reused after being cleaned. This can save on water and chemical costs, and also reduce the frequency of sand filter maintenance required.
  5. Lightweight and compact: Pool filter balls are lightweight and compact, making them easy to transport and store. They also don't require as much space in your filtration system as traditional filter media.
  6. Salt water pool friendly: Enjoy the benefits of soft water combined with excellent filtration.

Pool Filter Balls vs Sand

When comparing pool filter balls vs sand filter media there are some advantages and disadvantages that may or may not be appealing to all pool owners. It's important to consider your individual needs and preferences as well as budget, when deciding which filter media to your use. Here are some of the key differences between the two filter media types:

  1. Filtration efficiency: Pool filter balls are designed to have a higher filtration efficiency than sand. They can filter particles as small as 5 microns, while sand typically filters particles between 20-50 microns. This means that pool filter balls can remove smaller particles from the water, resulting in cleaner and clearer pool water.
  2. Lifespan: Pool filter media balls have a longer lifespan than sand, typically lasting 2-3 years before needing to be replaced, compared to sand which usually needs to be replaced annually.
  3. Maintenance: Both filter balls and sand require regular maintenance to ensure optimal performance. However, filter balls are easier to clean and maintain than sand, which requires backwashing and rinsing.
  4. Cost: Filter balls are more expensive than sand upfront, but their longer lifespan can make them more cost-effective in the long run.
  5. Installation: Installing filter balls is relatively easy and straightforward, while installing sand can be more complex and may require professional installation.
  6. Environmental impact: Synthetic filter media balls are made of recycled materials and are considered to be more environmentally friendly than sand, which can have negative environmental impacts when disposed of.

Problems with Pool Filter Balls

While they off many benefits as we've mentioned above such as longer filter cycles, improved filtration and ease of maintenance, there have been reported problems for some pool owners. Many of these problems can be avoided by following the manufacturer's instructions including cleaning the filter regularly and maintaining balanced water chemistry. The following are some of the potential problems with pool filter balls:

  1. Clogging: They can clog over time, reducing the efficiency of the filter, although this will likely only happen when the filter is not cleaned regularly or if there is a high concentration of debris or oil in the pool water.
  2. Cost: While they may have a longer lifespan than traditional filter media, they can be more expensive upfront.
  3. Compatibility: Pool filter balls may not be compatible with all types of sand pool filters. It is important to check with the manufacturer before using them in your pool filter.
  4. Durability: They can break down over time and may need to be replaced more frequently than traditional filter media. 
  5. Water flow: They can reduce the water flow in their pool system, which can lead to reduced filtration efficiency and potentially cause damage to the pump and other equipment.
