Why can't the top tank hold exactly the purifier's advertised capacity?

Gravity water purifiers, such as the Pure Filtersmodels, operate with two separate tanks. The capacity indicated (e.g. 9L for the Pure Filters Home 9L) corresponds to the total capacity of the lower tank once fully filled.

The upper tank has a slightly lower capacity because:

• The filters take up space inside.
• Some of the water remains retained in the filters to ensure effective filtration.

How do I fill my purifier correctly to reach the maximum advertised capacity?

To make full use of the purifier's capacity, follow these steps:

• Fill the top bowl almost to the brim.
• Allow some of the water to drain into the bottom bowl.
• Add water to the top bowl again to fill it.
• Repeat as necessary until the bottom bowl is full.

This operation is normal and specific to all gravity systems on the market.

Why does the depth of the Pure Filters Family 12L look different from the advertisement?

Some customers measure the depth without considering the edges of the purifier. However, the official measurement includes these edges, which are an integral part of the product design.

The right way to measure:

• With the lid in place, taking into account the overflow of the lid.
• Or by measuring the bottom tank, integrating the edges.

If you only measure the inner part or the top of the upper tank, you will get a lower value than advertised.

Why is this measurement mode used for all models?

Dimensions include edges as they are part of the purifier's structure and influence its actual footprint on a countertop.

This is the standard used for all gravity systems, to ensure a consistent comparison between models on the market.
