Overview
Aquasure builds this tall fiberglass softener tank for a whole house, with a digital metered control head that backwashes on demand and a pre-filter named in the title. It is sized for a household with several bathrooms.
Its strength is on-demand regeneration, which the description says saves a lot of water, plus a pre-filter for the supply. The limitation is conflicting data: a reverse osmosis field and a capacity in gallons sit alongside the grain rating.
Who it's for
Houses with several bathrooms and a family of up to five are the sizing the description gives. Small apartments, or buyers wanting drinking water purification, should look at a smaller softener or an RO unit.
Pros and cons
- Whole house coverage
- Digital metered control head
- Regenerates only when needed
- Pre-filter named in title
- Conflicting capacity and RO entries
- Flow rate and salt use not listed
Performance notes
A metered control counts the water used and regenerates the resin only when capacity runs low, which saves water and salt. Hardness removal depends on resin volume and the household's actual hardness, which the listing does not give.
