- For carafes Aqua Optima, this is "official" cartridges designed specifically for these pitchers - and so there is no compatibility issues. In addition, the price / quality ratio is rather interesting.
- For Brita jugs, the situation is clearly different as these cartridges have compatibility "questionable". On two different models of pitcher, I encountered the same problem: the cartridge is higher than the slot and it remains unfiltered residual volume. Personally, this delay does not encourage me to purchase supplies from another brand for my Brita pitchers.
For cons, the price of consumables can motivate the consumer to move towards a carafe Aqua optima and associated cartridges.
