er....ok i will try to take some picture for u tonight. I buy off 1 time. in and out total rm5100. if just the apolo for outdoor should be 2k-3k. I can't rmb. the reason I choose this is because my company are using their product, im quite satisfy with the water result. and the outer skin is made on stainless steel. so no cracking or need additional cloth to cover it. And I like the backwash function, it is to clean up the filter, I can use the backwash water wash my car porch. But still every 6month will have a technician come to my house to clean up the filter in a more proper way.
