Are cheaper compatible hot tub filters good enough?

[Zach91]

Genuine filters cost more, but compatible ones are everywhere. Are they fine, or should I stick to branded?

[QuantumLeap]

Compatible filters can be fine if the size and type match. Pool Filters Cartridges Type S1 Compatible for Intex PureSpa is one example of a compatible S1 style listing

If you prefer genuine branded filters, Intex 29001E PureSpa Type S1 Filter Cartridge 2 Pack is the safer choice

[FrostBear]

The risk with cheaper filters is weaker filtration or poor fit. I bought some from china and the foam went like pva washing pods. Not good in a hot tub

For heavy use, I would test a small pack first before buying loads
