i'd say it's quite a reasonable filter for that price. whats more u got it for free. urs is a ceramic one while the cosway one has the ceramic plus plus plus plus. u win what, where got up car? up car is when u pay for it then u realise not so worth it then only up car feeling. u ok or not?

the ceramic one can be taken out n cleaned using a brush provided with the filter. all 4 filters have their own life expectency - i believe it is stated inside the manual; u don need to change all four at once la, so u're not spending 450 at one go unless u too rich u wanna change all four at once.

TS get it for free. use it until cannot use, then give it away if u feel the maintenance is up car la

cosway members enjoy 50 percent off for each type of filter
