Q&A

Where are these filters discarded??

Used cartridges can normally be placed in your regular household trash. They are made primarily from polyester and polypropylene and are not generally accepted in curbside recycling programs.

How long does it last?

There’s no fixed lifespan—it depends on your sediment load and water usage. This pleated 5-micron cartridge is designed for longer life thanks to high surface area, but a common guideline is about 3–6 months, replacing sooner if you see a noticeable pressure/flow drop (gauges make this easiest to track).

Will this fit a standard 20"x4.5" Big Blue filter housing?

No. That cartridge has a double O-ring (SOE) end, which locks onto a post inside the housing. A standard 20" × 4.5" Big Blue housing uses DOE (double-open-end) cartridges. This fits this housing : https://uswatersystems.com/products/4-5-x-20-high-flow-filter-housing-1-reinforced

When installing do we remove the strap that is around the filter?

No, the strap should remain on the filter.
