BioStone 0.1 micron water filter for water ionizerAlkaViva VESTA GL 988 (GSF)


  • GSF water filter(Biostone 0.1 micron) for position #2 AlkaViva VESTA GL 988 water ionizer
  • Bacteria and particulate removal to .1 micron
  • Contains tourmaline for optimal water ionization
  • Contains GAC media for chemical removal
  • Contains natural calcium for water pH balancing



The Standard GSF(GlStandardFilter) Replacement water filter for AlkaViva Vesta GL 988 water ionizer incorporates granular activated carbon, tourmaline and calcium and is similar to BioStone 0.1 water filter for other water ionizers. This water filter is great for normal municipal supplied tap water with no carcinogens above the normal allowed levels. It will easily remove chlorine and bacteria, and will clean the water very nicely of most other normal particulates.


The Standard GSF(GlStandardFilter) Replacement water filter for AlkaViva Vesta GL 988 water ionizer removes chlorine, bad taste, Giardia, Cryptosporidium, all other common water micro-organisms and other contaminants from the incoming water. What remains is great tasting, CLEAN & HEALTHY water PLUS the essential alkalizing minerals still intact.


Vesta GL 988 GSF Water Filter Composition

Silver Impregnated Carbon: The water filtering function uses active carbon which is carbon created by burning palm trees at high temperature. This is a secondary pollution-prevention function.

Special Textile water Filter: This water filter contains a triple textile water filter, so no need to worry about germ propagation.

Tourmaline Ceramic:

The tourmaline in this patented, state-of-the-art filter really makes a difference in the ability of the water to carry an ionized charge naturally. As the water passes over the tourmaline crystals the ORP (Oxygen Reduction Potential) is naturally decreased and the water made more bio-available. What this means is if water passes through your water ionizer – even with the power turned off – the water will come out more ionized!

This material naturally produces an 0.03 mA electric current. It has composite functions such as absorption / repulsion, anion formation, etc, that are highly effective for activating tap water.


Calcium not only helps to slightly remineralize the water but also naturally sweetens the water and changes volatile fluorine molecules into a benign compound (calcium fluoride).

Enhances electrolysis capacity, provides an important mineral and improves the taste of the water.

Capacity: 1000 gallons/4000 liters of filtered & ionized water
Best Used For: Municipally Supplied Water
water Filter Media: GAC, Tourmaline, Calcium
Estimated water filter Life (1-2 people): 9-12 months
Estimated water filter Life (3-5 people): 5-6 months
Fits Models:  AlkaViva Vesta GL 988 water ionizer  (position #2) ONLY
Bottom Line: Does a decent job at removing contaminants from tap water as any GAC water filter would do. You’d definitely be better off with the UltraWater Filter for Samsung Vesta water ionizer 


How do I know when I need to change this internal water ionizer filter?

This internal water ionizer filter was made to be used in the water filter #1 position of your AlkaViva Vesta GL 988 water ionizer  (left housing door). The water filter indicators on the front of the AlkaViva Vesta GL 988 water ionizer shows both water filter life indicators – you must be looking at the water filter #2 indicator. When the water filter indicator reaches all 5 bars, and starts blinking, it’s time to replace the water filter. Make sure you are looking at the water filter #2  life indicator, and not water filter #1 life indicator. Also, remember to reset the water  filter life indicator once you install the new water filter.

Can this water filter be used in any other water ionizers?

NO, water filter for AlkaViva Vesta GL 988 water ionizer  GL-988 ONLY.

It has been two years since I changed my water filter last, but I don’t use the AlkaViva Vesta GL 988 water ionizer  that often. Do I still need to change the water filter(s)?

YES. Even though you may only be using the AlkaViva Vesta GL 988 water ionizer  once in a while, the water filter media and housing is filled with water. The integrity of the internal water filter media will begin to diminish over time, and the inside of the water filter will degrade. Therefore, it is imperative that you change your water filter at least once every 12 months

Is this a Biostone water filter? Does it contain tourmaline?

This filter does contain Tourmaline, but the name of the water filter just doesn’t use the word “Biostone”, as with other AlkaViva water filter names.

What is tourmaline? How does it effect the water in my AlkaViva Vesta GL 988 water ionizer

Tourmaline naturally emits far infrared energy (FIR) and changes the surface tension of the water, making it

(a) easier to process for the AlkaViva Vesta GL 988 water ionizer

(b) beginning the negative ion creation process.

In practical terms it means you’ll get better water by far, even with the “Purified Only” water setting, and you’ll get more antioxidant effect with the alkalized water, without an accompanying increase in alkalinity. It’s like an antioxidant ‘supercharger’.

What is the source of the calcium in the Vesta GL 988 GSF water filter?

The calcium in the Vesta GL 988 GSF water filter for is premium food grade calcium and comes from natural Japanese mineral mines.
