but recommend to place another dirt filter before going into this filter

yes.. only the filter

therefore i would recommend to place another cheapo filter before it.. cause panasonic filter more expensive.
there's replacement indicator for u to know

however, the filtration might be less effective than more expensive model

From 2015 to 2017 the filter price raised from 500 to 700 now. That's 100 increase in a year. Cibai punya Amway filter. More expensive to maintain like Volvo.

If filter element keep increasing every year, what's the point? You could buy a new filter unit from lots of brands yearly.not just element only.
