The Aquasana EQ-1000 Whole House Filter unit reduces >97% of the chlorine coming into your home through the municipal water supply. The EQ-1000 has three filtration stages to optimize contaminant reduction: a five-micron pre-filter to remove rust, dirt and microscopic particles; a tank containing a blend of copper-zinc oxidation media and crushed mineral stone to reduce chlorine and balance the pH; and a final tank containing a high-grade activated carbon for final reduction of chlorine and other contaminants. Enjoy great-tasting and odor-free filtered water from every tap or shower in your home. The unit comes complete with main filter unit, pre-filter, installation kit, shut-off valve and all the required hardware. Unlike water softeners, the EQ-1000 does not require salt, back-flushing or electricity to operate. The filtration tanks last for ten years or 1,000,000 gallons. The Premium Whole House Filter comes with a 90-day satisfaction guarantee and a ten-year warranty. Compare to Culligan and other water softeners, and you'll see why the reviews agree that Aquasana has great filtration technology at a great value. For a powerful water filter at a great price, think Aquasana. It means healthy water. Not Aquasauna, Aqua Sana or Aguasana. Made in the USA by Aquasana, Inc, a Texas Corporation.
