Comparison Aquafilter FRO5MPAJG vs Aquafilter FRO5JGMP

The number of purification stages provided for in the filter design. At each stage, water passes through its own filter element, clearing itself of certain contaminants; in this case, the steps are arranged in order from coarser cleaning to finer. For example, a three-stage system may look like this: the first stage is mechanical removal of impurities, the second stage is the removal of ferrous, and the third is filtration through a carbon cartridge.

The more stages of purification — the more advanced the filter is considered, the cleaner water it usually provides at the outlet. Accordingly, this moment largely depends on the purpose (see “Type”): for example, multi-stage filtration is quite rare in main models, it is practically not used at all in pre-filters, but the number of stages can reach 9 in models for sink.

Models of replaceable cartridges for which the filter is designed. Knowing the names of models, it will be much easier for you to find a replacement for an exhausted cartridge. In addition, the options directly named by the manufacturer are fully compatible with the filter and correspond to official specifications, while there is no such guarantee for "non-native" cartridges.

Several names in this paragraph are usually indicated for filters with multi-stage filtration (see "Stages of purification") — a cartridge for each stage.

The diameter of the pipes to which the filter is designed to be connected; indicated only for models with water connection, see "Connection". In plumbing, pipes of standard diameters are usually used, and inches are used for measurement — for example, 0.75", 1", etc. Most filters are equipped with a set of adapters for different pipe diameters, therefore, most likely there will be no connection problems, even if the initial diameters do not match. Nevertheless, it is best to choose a filter that matches your water supply in terms of fitting size — in this case, the connection is more reliable, and compliance with the claimed characteristics will be complete.
