Aquasana Shower Filter AQ-4100 vs Philips Shower Filter

Buy the Aquasana AQ-4100 if you want a complete unit: it ships with a multi-setting handheld shower head and carries NSF/ANSI 177 and 61 certification, and 1,869 owners rate it 4.4 out of 5. Buy the Philips if you already like your shower head and want a longer-lasting filter body with a chrome finish that matches your fixtures. Both are carbon/KDF filters that cut chlorine and neither reduces TDS, so the real split is included hardware and certification versus filter capacity and finish.

• Choose the Aquasana AQ-4100 if you want a certified filter and a new handheld shower head in one box, with a 2.5 GPM flow that keeps pressure up.
• Choose the Philips Shower Filter if you want to keep your existing handheld or rainfall head and get a longer filter life in a chrome body.
