Which is better for a Philips AWP1775 shower filter?

The GLACIER FRESH Z108 is made specifically for the AWP1775 housing, so it is the direct fit. The Philips cartridge is the OEM part and carries the NSF-certified KDF claim, but confirm it matches your housing model before buying.

Is the GLACIER FRESH cartridge as good as the Philips one?

Both use KDF media and rate 50,000 L with a 4-6 month change interval. The Philips part adds an NSF certification and a stated 8 L/min flow rate, which the GLACIER FRESH listing does not provide.

How often do I replace either cartridge?

Every 4-6 months, or sooner with hard or heavily chlorinated water. Both are rated for 50,000 L, which is roughly a year of typical showering.

Is the 3-pack worth it over the single Philips cartridge?

At the same $29.99, the 3-pack gives you three cartridges for the price of one Philips cartridge. You trade the NSF claim and brand fit for lower cost per refill.

Will either one reduce my shower pressure?

Philips states its cartridge does not reduce existing pressure at 8 L/min. GLACIER FRESH does not publish a flow rate, so pressure drop is unverified.

Do both remove chlorine?

Yes, KDF media reduces residual chlorine in both. The Philips listing also cites rust and sediment removal through its double mesh stage.

Philips Shower Filter Cartridge AWP175 vs GLACIER FRESH Shower Filter Cartridge

Both are KDF shower filter cartridges at the same price, $29.99 at Amazon as of November 6, 2026. Buy the Philips cartridge if you want the brand-name part with an NSF-certified KDF claim and a stated 8 L/min flow rate. Buy the GLACIER FRESH Z108 if you want a compatible replacement for the Philips AWP1775 housing and a three-pack option. The real difference is fit and certification claims, not price.
