Is Glass Filter Media Better than Sand?

To keep your pool water free of various contaminants, the right type of filter media should be used. Both glass and sand filter media has to be changed after a while since if it’s left too long the filter can stop doing its job due to clogging. This will result in poor water circulation and dirty pool water.

The traditional sand filter media is no longer as effective since there’s now glass filter media available. It can replace sand in every filtration application thanks to its more advanced design. Most glass media is processed specifically to gain the ideal size and are manufactured from a certain glass type. The surface area is then negatively charged so that the media can attract small particles that sand can’t capture through electrostatic filtering.

Here are some of the benefits of using glass filter media for your pool:

A better cleaning ability

Glass can filter particles that are around 5-10 microns in size while sand can only filter particles that are 30 microns.

Superior longevity

Sand media has to be replaced every 3-5 years depending on the quality of the product and the amount of dirt passing through the filter regularly. On the other hand, glass filter media can last up to a decade.

Difference in backwashing

To clean a swimming pool filter, a process called backwashing has to be done. It is initiated by reversing the flow of water to get rid of the contaminants collected in the filter.

Compared to glass media, sand takes longer backwashing because of its high volume. Glass has a faster backwash because its material is less dense and much lighter. This allows for faster cleaning and also results in saving plenty of water.

There are plenty of glass filter media products available in the market today, but if you’re looking for a high-quality, eco-friendly and affordable type, then you can’t go wrong with EcoClear which is made from 100% recycled glass.
