Im using model SHP-FUA28EW now need to change filter.
But check around mostly selling about RM200++ thats about 1/2 of the new set price.
Why does the filter so expensive?

Is there any cheaper alternative?

I thought every model/brand uses custom-made HEPA filter?

An air purifier is basically just a fan + HEPA filter (and sometimes particle counter) right?

HEPA filter is the expensive component of an air purifier. No point buying an pricey filter and use it with a cheap fan.
