Spa water tends to look its best when you start with clean water, and that is where a spa fill filter helps. Tap water can carry bits of grit, fine sediment, or a bit of rust from the plumbing, and all of that usually ends up in the spa if nothing stops it. Using a fill filter cuts most of that out before the water even reaches the pool, which makes the first few days of running the spa a lot easier.
The Magnum spa fill cartridges in this range are made here in New Zealand and use a tight 5 micron polyspun media. They connect straight to a garden hose, so there is nothing fiddly to set up. The flow stays steady, and once the spa is full, you just disconnect and store it for the next use. It is a simple add-on that helps protect the main spa filter and keeps the water clearer from the start.

FAQs
1. What does a spa fill filter do?
It filters out fine sediment and particles from your tap water as you fill the spa, helping the water start clean and reducing strain on your main spa filter.
2. Do I still need my regular spa filter?
Yes. The fill filter supports your main spa filter but does not replace it. It simply reduces the load before the water enters the spa.
3. How often should I replace a spa fill cartridge?
Most people replace it every few fills, depending on water quality and how much sediment is present in the supply.
4. How do I connect the fill filter?
It attaches to a standard garden hose using the built-in male hose fitting. Once connected, you can fill the spa as normal.
5. Will this improve water clarity?
Yes. Starting with cleaner fill water helps reduce cloudiness and makes it easier for the spa’s main filtration system to maintain clarity.
