Safest, most effective & economical filtration media on the market

Filterglass is finely crushed recycled glass for pool, industrial, and environmental filtration that provides outstanding water clarity and quality.  A direct replacement for sand or other filtration medias in both freshwater and saltwater pools.

 Superior Cleaning

  • Increased water clarity due to a 25% reduction in turbidity
  • Filters smaller particles down to about 5 microns
  • Negative surface charge attracts positively charged iron and maganese, which is easily released upon back flushing
  • Glass is amorphous (non-crystalline) in nature, meaning the particles have smooth sides and are less likely to support algae and fungal growth
  • Compatible with chemical pre-treatment
  • Reports have shown up to 70% of bacteria removed

Lower Operating Costs

  • Lasts longer, minimum life of 5 years
  • Low attrition of particles in fines, due to smooth surface, which prevents channeling and blockage; this lengthens the intervals between media changes
  • Requires about 20% less media (by weight)
  • Compatible with salt water chlorination

Safer To Use

  • No crystalline silica, resulting in better lung protection and a far healthier environment; silica is a TYPE 1 known aspirant carcinogen
  • 100% environmentally sustainable

Because Filterglass cleans better, you save energy, operating costs and extend the life of your filter.  Using Filterglass results not only in outstanding performance, but also in real cost benefits over the life of a filter bed.
