How much filter glass does a 500 mm filter require?

Choosing the right amount of filter glass is key to maintaining the performance of your filtration system. If you’re wondering how much filter glass does a 500 filter have, you’ve come to the right place. In this guide, we’ll explain not only how much you need, but also how it compares to other sized filters and what benefits this type of filter media offers.

What does a “500 filter” mean?

When we talk about a 500 filter, we’re referring to the diameter of the filter in millimeters. That is, a 500 mm diameter filter is a standard size for many residential and semi-professional pools.

This measurement determines the volume of the filter bed required and, therefore, the amount of filter material to add.

How much filter glass do I need for a 500 mm filter?

Filter glass is a modern alternative to traditional sand, with improved filtration properties and greater durability. Typically, 80% of the weight of sand that would be used is used.

For the 500 mm filter, the sand required is 75 kg and the filter glass required is 60 kg. This value may vary slightly depending on the filter manufacturer, so it’s always a good idea to check the equipment manual.

What about a 600 mm filter?

If you have a slightly larger filter, like the 600 mm filter, the amount of filter glass also increases. In this case, 100 kg of sand is required, and 80 kg of filter glass is required.

How many kilos of filter glass do I need?

The most accurate way to calculate this is with this formula:

Recommended sand weight x 0.8 = kg of filter glass required

This is because glass is lighter and more efficient, so less of it is required to provide the same or better results.

Advantages of glass filters over sand

• Reduce backwashing frequency: saving water and energy.
• Longer life: up to 10 years without needing replacement.
• Reduction in the use of chemicals:Improves water quality.
