# AQUA CREST AQ-UP16 Under-Sink Water Filter, 11,000-Gallon Capacity

AQUA CREST AQ-UP16 is an under-sink filter system for municipal water, using activated carbon and sedimentation to reduce chlorine, sediment and taste and odour concerns. Its claimed 11,000-gallon capacity and 4-litre-per-minute flow rate suit buyers seeking a direct-to-faucet filter, but it is not intended for well water and does not reduce TDS.

## At a glance

- The listing claims up to 99.52% chlorine reduction, based on an SGS test for 10 unit volumes of chlorine reduction. Actual performance may vary.
- A PP sediment layer and coconut shell carbon are claimed to reduce sand, rust, taste and odour while retaining essential minerals.
- Designed for cold water and municipal water only. The listing says it is not suitable for well water and does not reduce TDS.
- Manufacturer claims a 4 L/min flow rate and a filter life of up to 12 months, with actual lifespan dependent on water quality and use.

## Pros

- Direct-to-kitchen-faucet under-sink setup avoids requiring a separate filter jug.
- The stated 4 L/min flow rate may suit households that want to fill glasses and cooking vessels without a slow dispense.
- The claimed 11,000-gallon capacity and 12-month filter life provide clear replacement guidance, subject to usage and water quality.

## Cons

- It does not reduce TDS, so it is not suited to buyers seeking TDS reduction.
- The manufacturer limits its use to municipal water and says not to use it with well water.
- Cold-water supply only. The listing warns not to use hot water.

## Before you buy

- The 99.52% chlorine-reduction claim is qualified by testing for 10 unit volumes, and actual performance may vary. The listing gives a 12-month filter life but also says lifespan depends on water quality and use. Dimensions are inconsistent: the specifications list 31.2L x 9.9W x 9.1H centimetres, while a feature states 8.15 × 8.15 × 24.31 cm. Confirm the size and fitting compatibility before installation.

## A good fit for

- Households on municipal water looking for an under-sink, direct-to-faucet filter focused on chlorine, sediment and taste or odour.
- Buyers who want a stated high flow rate and a long claimed cartridge capacity for drinking and cooking water.

## Less suited to

- Well-water users, since the listing says this system is for municipal water only.
- Buyers who need TDS reduction or hot-water filtration.

## Customer feedback

The supplied evidence contains aggregate ratings but no customer comments, so it does not establish specific praised features or complaints. The rating distribution is positive in this small sample, but it cannot confirm filtration performance or resolve the listing's installation-size discrepancy. Buyers should weigh the stated municipal-water limitation and lack of TDS reduction against their needs.
