Does the GLACIER FRESH cartridge fit a Philips AWP1775?

Yes. It is sold as a replacement cartridge for the Philips AWP1775 shower filter, the same housing the Philips AWP175/37 fits.

Which filters better?

Both use KDF media rated at 50,000 L. GLACIER FRESH lists 3 stages; Philips lists KDF with double mesh and NSF certification. On paper the Philips certification claim is the stronger documented point.

How often do I replace each?

Philips rates its cartridge at about 4 months. GLACIER FRESH rates its cartridges at 4–6 months. Actual life depends on your water volume and chlorine level.

Is the Philips worth the extra per cartridge?

Only if you want the OEM part and NSF certification. Per cartridge it costs about $6 more, and the GLACIER FRESH pack covers roughly a year.
