Just got my second set of these filters and I'm still loving them! Perfect fit for my Watts WP5-50 system - no more hunting for compatible filters.

The difference in water taste is crazy. Here in Phoenix with our hard water, the first two filters get absolutely disgusting (in a good way? Means they're working!). My morning coffee tastes so much better now.

Installation was... an adventure. Not gonna lie, it took some wrestling with the connections. But once everything was in place? Magic. My RO system runs like it's brand new again.

Pro tip: Mark your calendar for replacements! The carbon/sediment filters need changing every 6-12 months, but that RO membrane lasts ages (2-3 years).

Only gripe? That post-filter sizing issue some reviewers mentioned. Mine fit fine, but seems like quality control might be hit or miss there.

Overall? 4.5/5 stars. Keeps my water crisp and clean without breaking the bank. Will definitely reorder when needed!
