AISTRO-2 In-line Softener and iron reducing cartridge

2" x 10" in-line water softening and iron removal cartridge. Contains FDA compliant ion exchange resin - 1/4" NPT.


     Aquafilter offers AISTRO-2 In-line Softener and iron reducing cartridges (AISTRO-2, AISTRO-2-QC and AISTRO-2-QM) suitable for POU (Point of Use) installations. Through its double media consisted of ion exchange-based resins, AISTRO-2 cartridges effectively reduce water hardness as well as decrease iron concentration. In case your feed water contains a high concentration of suspended matter, AISTRO-2 is commonly preceded by a Sediment filter to avoid a detriment of the cartridge performance. AISTRO-2 fits most 1/4” water lines and requires no additional tools for its installation.
