Can You Use Play Sand for Pool Filter?

Many pool owners wonder whether it is possible to use play sand instead of expensive pool filter sand for their pool filters. While it may seem like a cost-effective alternative, there are several factors to consider before making the switch. In this article, we will explore the pros and cons of using play sand for pool filters and provide you with essential information to make an informed decision.

What is Play Sand?

Play sand is a type of sand used for children's sandboxes, play areas, and other recreational purposes. It is made of finely ground silica or quartz and is free of impurities such as clay, silt, and organic matter. Play sand is often less expensive than pool filter sand, making it an attractive option for some pool owners.

Pros of Using Play Sand for Pool Filters

1. Cost-effective: Play sand is significantly cheaper than pool filter sand, making it a more affordable option for those on a tight budget.

2. Availability: Play sand is readily available at most hardware stores, making it a convenient option for those who need to replace their pool filter sand quickly.

3. Similar Composition: According to some pool owners who have used play sand for their pool filters, play sand has a similar composition to pool filter sand.

Cons of Using Play Sand for Pool Filters

1. Inconsistent Grain Size: Play sand has a less consistent grain size than pool filter sand, which can lead to clogging and reduced pool filter efficiency.

2. Not Certified: While pool filter sand is certified by NSF (National Sanitation Foundation) for use in pool filters, play sand is not certified. This means that its effectiveness and safety for use in pool filters are not guaranteed.

3. May Contain Contaminants: Play sand is not specifically designed for pool use and may contain contaminants such as clay, silt, and organic matter that can clog pool filters and reduce their effectiveness.

4. Shorter Lifespan: Due to its inconsistent grain size and potential for contaminants, play sand may need to be replaced more frequently than pool filter sand, which can increase overall pool maintenance costs.

Can You Convert Your Pool Filter to Use Play Sand?

While it may be tempting to save money by using play sand instead of pool filter sand, it is not recommended. Pool filters are designed to use specific types of media, and using anything else can be detrimental to their efficiency and lifespan. If you are considering converting your pool filter to use play sand, we recommend consulting with a professional pool service technician to ensure that the conversion is safe and effective.


While play sand may seem like an attractive option for pool owners looking to save money, using it for pool filters can lead to clogging, reduced efficiency, and increased maintenance costs. Pool filter sand is certified for pool use and is specifically designed to provide efficient filtration. We recommend using pool filter sand for your pool filter to ensure the highest possible quality of pool water and reduce maintenance costs down the line.
