Perfect Steel (PS) got several models. The body is either fibre or stainless steel while the head or valve can be either plastic or stainless steel. THe price difference between plastic head and stainless steel head is RM 250. The normal plastic head is actually good enough. However, if u wan to get THE BEST for your family like Jo_da48, u can upgrade it to a stainless steel head.

PS has good after sales service like what Jo_da48 has mentioned, PS OEM for other brands like alphamax, they are quite reputable in the market but not popular as they lack of advertising.

Sand filters are basically very durable and better than membrane filter. It is true that membrane filter has better filtration but if your water pressure is strong like Jo_da48, there is a high possibility that the membrane will burst, will cost u RM 400 to replace the membrane. A sand filter on the other hand will not spoil but filtration will b less effective.

THis is the model that Jo_da48 bought from me. You can view the spec as per attached file below
