HW‑303 White Sponge – white sponge, 1 piece

This is a single white replacement sponge for the SunSun HW-303 and HW-303B filters. It suits aquarists who need a spare filter media insert for these models and want to confirm it matches their existing filter before ordering.

Why it matters

• Model-specific fit: the sponge is intended for the SunSun HW-303 and HW-303B filters, so the compatible models are stated directly in the product name and description.
• Original product: the supplier describes this as an original SunSun item, not a third-party substitute.
• Single unit: the offer covers one sponge, so the quantity is known before checkout.
• White colour: the sponge is white, which distinguishes it from other media in the filter when cleaning or replacing parts.

What it works with

The sponge is a replacement part for the SunSun HW-303 and HW-303B canister filters and is used in aquariums running these models. Before ordering, check that your filter is an HW-303 or HW-303B, as the listing does not cover other SunSun models.
