H401 Heavy Duty

NSF is a recognized international standard for products and materials that come into contact with water and food. In a water filter, the NSF mark helps ensure that the filter materials are suitable for use in drinking water systems and meet relevant quality and safety requirements. The H401 filter carries the NSF mark along with certification from the Standards Institute of Israel / MATI, therefore providing an important layer of confidence in a product that comes into direct contact with drinking water.

The Standards Institute of Israel / MATI Israeli Standard is an important certification for water filtration products marketed in Israel. When a water filter carries MATI certification, it means that it has been tested in accordance with relevant regulatory requirements for use in drinking water. For the customer, this is a significant sign of trust in choosing an original, high-quality HDS filter.

Activated coconut charcoal is a high-quality filter material commonly used in advanced water systems.

It is recommended that the H401 filter be replaced every 9–12 months, depending on the nature of use, water quality, and actual consumption. In cases of decreased water flow, a change in taste or odor, or particularly heavy use, earlier replacement may be necessary.
Timely replacement helps maintain a good water experience and proper functioning of the filtration system.

In most cases, replacing an H401 filter is a simple operation that does not require a plumber: close the supply tap, remove the old filter, install the new filter, turn on the water and check for leaks. After installation, run water through the system for several minutes according to the manufacturer's instructions.
If you are unsure how to perform the replacement, it is recommended that you contact HDS Customer Service for guidance.
