Sand filters are the most common type of pool filters as they require the least amount of maintenance compared to other types. However, the silica sand used as the media in sand filters has its drawbacks. The filtration efficiency of filters with sand media is not satisfactory. Also, the use of silica sand in the filter causes the system to suffer from severe pressure drop. In addition, bacteria accumulate on the surface of the sand and pollute the water. Accordingly, glass filter media has been developed as an alternative to sand filter media.
MEGAPOOL glass filter media is designed specifically for use in water filters and therefore, it comes from high quality glass. Unlike the products of other brands, MEGAPOOL glass is not produced from recycled glass to ensure that the product has never been in contact with contaminants. Crushed glass is then processed into angular grains with perfectly smooth surface. MEGAPOOL glass filter media is available in recycled packaging made of waterproof and UV-resistant polyethylene paper. This product is used in various areas, such as:
- Private and public swimming pools
- Spas
- Aquariums
- Advanced industrial facilities such as water and wastewater treatment plants, water parks, artificial lakes, RO water purifiers, fish farms and irrigation facilities
In filters with sand filter media, combination of layers with different sized grains is required to prevent the sand from clogging and to improve filter backwash. However, in filters with glass filter media, there is no need for a multi-layer filtration system and mainly two layers of silica are used. In addition, while a filter uses only the top six inches of the sand media bed, the filtration takes place through the entire bed depth of the glass media and therefore, filtration efficiency is improved.

Chemical Saving
Glass filter media filters out particles as small as three microns which helps filtration efficiency and reduces chemical treatment costs. Sand silica, on the other hand, is only effective in removing large particles (20 microns and larger) from water, and can only separate bacteria and other fine particles from water if a coagulant is added.
Bacteria accumulate on the surface of silica sand and form a biofilm to protect themselves against disinfectants. However, the smooth surface of glass silica discourages bacteria from attaching to the glass. This results in a healthier filter tank. There is also no need to increase the amount of disinfectant to kill bacteria.
Minimum Pressure Drop
Silica sand clogs easily and loses its ability to trap suspended particles. Clogging also causes severe pressure drop in the system. Consequently, channels gradually form in the silica sand bed and water entering the filter passes through these channels and leaves the filter without suspended particles being removed. However, the technology used in the production of MEGAPOOL glass filter media prevents the silica glass from clogging and the channels from forming.
Water and Electricity Saving
MEGAPOOL glass filter media is less dense than sand, requiring 20% less media to fill the same filter. Also, glass filter media will be backwashed quicker as the material is lighter and there is more space between the grains. This means that using glass media, you can save money on your water and electricity bills.
Durable and Recyclable
Over time, the silica sand becomes worn and they are no longer able to filter the suspended particles as well as it once did. This is while MEGAPOOL glass filter media is highly durable and resistant to friction. Filter silica sand needs be replaced every 3 to 5 years, but silica glass lasts at least 10 years and is recyclable.
