Whole House Water Filter Housings FAQ
What is a Big Blue whole house filter housing?
It’s a large-capacity housing unit that holds standard cartridges (typically 4‑½‑inch diameter) and is used as the outer shell in a whole-house filtration system. It’s built to handle high flow, large volume of water, and heavy-duty filtration tasks.
What sizes are available in this APEC Big Blue housing line?
APEC offers at least two main size options:
- 20‑inch whole house filter housing (for higher capacity, larger households)
- 10‑inch housing (smaller & more compact, but still standard)
What cartridges do these housings work with?
They accept standard 4‑½‑inch diameter whole house cartridges. For the 20‑inch housing, cartridges are longer to provide more capacity; the 10‑inch version uses the shorter length cartridges.
What are the benefits of choosing the 20‑inch Big Blue housing over the 10‑inch?
Advantages include:
- Higher capacity
- Ability to handle higher flow (good for large homes or higher usage).
- Better suited for situations with heavy sediment.
Will using a Big Blue whole house housing reduce water pressure?
No, APEC's housing is design to support large flow rates. Because the housings are large (especially the 20‑inch), with appropriate cartridge choice, they’re intended to maintain good pressure even with significant water demand.
What materials and build quality can I expect?
The housings are made from durable materials suitable for whole‑house use and designed for large capacity, heavy-flow, and high sediment conditions.
