Question 1

Does this 4-pack exactly match Hayward’s original C-7488 cartridge, or are there fit issues?**

Accepted Answer

The Unicel C-7488 is designed as a direct replacement for the Hayward C-7488 systems. However, some pool owners on Reddit and YouTube have noted that these cartridges can be about ¼-inch shorter than the OEM version, which may affect the seal on certain pool filter housings. We always suggest checking your current filter’s height and gasket type before ordering. If you’re unsure, measure the old cartridge top to bottom and compare it to the Unicel’s 7.5-inch height.

Question 2

I’ve seen a few TikTok videos showing damaged cartridges in shipping. How do you prevent that, and what’s the return process if one arrives bent?**

Accepted Answer

We take extra care in packing our 4-pack with reinforced cardboard and corner supports to minimize movement in transit. Still, accidents happen. If a cartridge arrives damaged (bent pleats, crushed ends, or split media), simply snap a photo and contact us within 48 hours. We’ll send a free replacement for the affected unit—not the whole pack—so you’re not stuck with three good filters and one dud.

Question 3

Are these better than the cheaper no-name cartridges on Amazon, or should I just buy those?**

Accepted Answer

Many bargain filters use a thinner, 100-gram media that collapses quickly. The Unicel uses a 150-gram polyester media that holds its shape longer, usually lasting a full season before replacement if cleaned monthly. In side-by-side tests by pool bloggers, the Unicel caught slightly more fine debris (down to 20 microns vs. 30 for most generics). So, while they’re priced higher than the absolute cheapest options, they beat them in durability and filtration consistency.

Question 4

How often do I need to clean or replace these cartridges?**

Accepted Answer

For a typical residential pool running 8–10 hours daily during summer, you should rinse these cartridges with a garden hose every 4 weeks to maintain good pressure. Plan to replace the entire set after 12 months or at the start of the next season. If you use a filter cleaner spray or soak, you might extend that to 15 months, but watch for flattened pleats—once the media starts collapsing, filtration drops fast.

Question 5

Do these work for both Hayward C-7480 and C-7488 models, or are they model-specific?**

Accepted Answer

The Unicel C-7488 is specifically made for the Hayward C-7488 system. It will physically fit into some C-7480 housings, but users on pool forums report a looser fit that can allow unfiltered water to bypass the cartridge. If you own a C-7480, we recommend measuring your existing filter’s length first. For a perfect seal and consistent pressure, sticking with the model number listed on your filter’s label is your safest bet.
