U change both filters yearly? most ppl dont change AP902 yearly, hence water is getting dirtier and AP EASY getting clogged faster.

If u r not staying in a condo, i suggest u change AP902 to an outdoor filter with backwash, also change AP EASY if u wanna save on maintenance cost.

AP902 replacement is RM 600
AP EASY REPLACEMENT is RM 300

cost per year is RM 600 + (RM 300 x2) = RM 1200, isnt that too costly?

ie :

Get A sand filter + Aquaphor eco indoor filter = RM 2299 + Free replacement x 1 set

First year : RM 2299 (Before trade in Promo)
Second year : FREE
Third Year : RM 420
Forth year : RM 420
Fifth Year : RM 420 + RM 380 (sand replacement)
Total RM 3939 for 5 years

If continue with your current filter is RM 1200 x 5 = RM 6000 almost 50% saving. Save more with trade in promo

Sand Vs AP902
Filtration wise AP902 is better and quite consistent if u change it every year but sand can backwash hence you dont need to change every year.
If u wan better filtration get MEMBRANE FILTER, they are the cleanest but not recommended if ur incoming pressure is weak. Recommended 2bar to 2.5bar is sufficient which most housing area do have.

AP Easy Vs Aquaphor
AP easy consist of a small carbon block with filtration of 0.5 micron, hence recommend to change 6 months compared to other 3M model (1 year). Aquaphor consist of 3 cartridges (2 bigger size carbon block + 1 hallow fibre memrane) with filtration 0.1 micron. So changing it = an upgrade in water quality and reduction in maintenance cost

If u are staying in a condo, unable to install those big filters with backwash, then add this (as per video for RM 150) before your AP902 to pro-long the lifespan and change AP EASY to upgrade the filtration and lower maintenance cost.

if in condo usually the poe after meter coming through where ? from yard ?
