Comparison Atoll A-550p Max vs Atoll A-550 Max

The number of flasks in the filter makes it clear how many water cartridges can be installed in it. For a filter for sink, in most cases there are three flasks. If we are talking about reverse osmosis, then flasks do not mean a membrane, post-filter, etc. since their installation does not provide a separate container. But these types of processing are taken into account in the stages of cleaning. The most obvious difference in the number of flasks is observed in the main filters, where the predominant weight per 1 flask, but there are also models for 2 flasks or even more.

The presence of a water mineralizer in the filter design. The mineralizer is usually a container filled with a special slowly dissolving mixture. Thanks to it, filtered water is saturated with various micronutrients: calcium, potassium, fluorine, ferrous (of course, not harmful colloidal ferrous, but another easily digestible form) and others. They have a positive effect on the human body and improve the taste of the water itself compared to completely purified water.

Mineralizers are found mainly in filters equipped with reverse osmosis systems (see above): the fact is that during the operation of such systems, not only harmful impurities are removed from the water, but also the mentioned micronutrients that got there naturally.

The filter has its own pump. This feature is found mainly in two types of filters. The first is reverse osmosis systems (see above): the operation of such filtration requires high pressure, but it is not always achieved at the inlet, and a pump, usually electric, is provided to increase the pressure. The second option is tourist filters (see "Type"), where the pump is designed to draw water from natural reservoirs; they have to be pumped manually.
