Hello all, I need to install a POE water filter for my condo. Only 2 people living in the house, so we won't be using a ton of water every month.

I have the following considerations:

1) Must be one of those compact membrane type filter (not enough space)
2) Under RM1k
3) Must be able to be backwashed
4) Replacement membrane/filter media easily obtainable and won't cost above RM600.

Any recommendations?
