Overview

About this product

The Dual AS4 Purifier is a portable and compact model, easy to install, that does not use electrical energy and can be fixed to the wall or placed on the kitchen sink or countertop. It is a complete solution for residences and offices, combining pre-filtration and purification in a single unit.

It has two filter elements: the first, made of non-toxic polypropylene (Filter Flux® technology), reduces dirt coming from the pipes, such as sand, mud, sludge and rust; the second, produced with compacted activated carbon (Carbon Block), has high efficiency in reducing chlorine, taste and unpleasant odor from the water.

Main benefits:

Dual filtration: sediment retention and chlorine reduction in a single unit
Disposable filter elements, no need for backwashing
Flow rate of 48 l/h
Does not use electrical energy
Compact format, occupying little space during installation
Practical installation, on wall or countertop

Usage recommendation: to ensure water quality, replacement of filter elements is recommended every 6,000 liters, 6 months or when a reduction in water flow is observed.

Compatible refill: Dual AS4 Refill (code 928-0010).

Complies with Ministry of Health Ordinance PRC MS nº 5/2017 and NBR 16098:2012 standard.
