Frequently asked questions

Bag housings hold a flexible filter bag rather than a rigid cartridge, and they're generally chosen for higher flow rates and larger volumes than cartridge housings can handle economically — common in commercial and industrial pre-treatment where you need to filter a lot of water without frequent element changes.

Stainless steel housings handle higher pressures and temperatures, resist corrosion better in demanding or chemically aggressive environments, and are generally preferred for commercial, industrial, and food & beverage installations where durability and hygiene standards matter more than upfront cost.

Bag housing and bag size need to match — check the specific housing's product page for its bag size designation (commonly size 1 or size 2) before ordering replacement bags, since a mismatched bag won't seal correctly in the housing.

Yes — that's one of the advantages of a housing system. The stainless steel housing itself is a durable, reusable vessel; only the filter bag inside is replaced once it's loaded with sediment, so you're not replacing the whole housing each time.

Spectrum INOX bag housings are available across a range of port sizes and connection types to suit different pipework, so check the specific product listing for the housing's inlet/outlet size and connection style before ordering — if you're unsure what you need, send us your pipe size and flow rate and we'll help you confirm the right housing.
