JBL - Combi Filter Basket II CP e za filtre JBL e401-2, e701-2 in e901-2

Having a project to get back into fresh water on a 250-300 liters and having an old JBL e700 second hand, I bought this improved prefilter which clogs less but officially intended only to upgrade the following ranges (JBL e701/e401 and e702/e402) ...not without a slight apprehension concerning compatibility (thickness => bad support of the tank seal => flooding ???) ... but no! It's perfectly compatible and it's just JBL trying to boost sales! So as I had previously bought a new rotor for e701/e702 I find myself with a filter equivalent to the e701 or e702 and just as quiet! What's more, the power consumption measured by myself of my old e700 model is exactly the same, i.e. 7.1 watts, as the new, supposedly more economical, generations! In fact, JBL used to display the maximum impulse consumption at pump start-up, as is customary with electric motors, but now displays the true average consumption of 7 watts! In other words, the only changes in energy consumption between versions are purely marketing-related ;-) (Translated review)
