Invigorated Water 15-Cup Alkaline Water Filter Pitcher: features and specs

The Invigorated Water 15-cup filter pitcher is a jug that filters tap water as you pour it in, then keeps the result cold in the fridge. The brand describes it as an alkaline pitcher, meaning its filter is designed to raise the pH of the water and improve taste. It is a large-capacity model for households that get through a lot of drinking water.

How a filter pitcher works

You fill the top reservoir with tap water, and gravity pulls it through the filter cartridge into the lower chamber. No plumbing, power or tools are involved. Pitcher filters like this one generally use layers of media, such as activated carbon for taste and odour and other materials for particles, and the water simply takes a little while to pass through.

Invigorated Water says this pitcher uses multi-stage filtration to reduce common impurities such as chlorine while keeping minerals in the water. As with any pitcher, results depend on your local water supply, so check the brand's documentation for what the filter is rated to do.

What "alkaline" means here

Alkaline water is water with a pH above 7. The brand says the pitcher produces "high-pH" water. In general, filters that do this use mineral-based media that dissolve slightly into the water. The effect is usually modest and varies with the starting water, so treat the pH claim as the brand's description rather than a guaranteed figure.

Filter life and replacements

Invigorated Water rates each filter for up to 96 gallons, or 360 litres. How quickly that runs out depends on how much you pour: a household filtering a few litres a day will work through a filter far more slowly than one refilling the pitcher repeatedly. Replacement filters are sold separately, and the brand lists them in 3-packs. Because filter life is a stated limit rather than a fixed date, it helps to note when you fit a new cartridge.

Size and design

The pitcher measures about 10.5 x 5.2 x 10.0 inches (roughly 27 x 13 x 25 cm) and weighs 1.5 lb (about 0.7 kg). It has an ergonomic handle and an anti-slip base. The brand says it fits most refrigerator doors, which is useful, though a full 15-cup jug is heavy, so check the door shelf's capacity. The body is made from BPA-free, food-grade plastic.

Who it suits

It suits households, offices and anyone who wants filtered drinking and cooking water without installing anything, and who would like a large jug so they refill less often. It can also replace single-use bottled water for everyday drinking.

What to check before you buy

• Fridge fit: measure your door shelf or main shelf height and depth against the pitcher's dimensions.
• Filter supply: confirm that you can get the matching replacement filters.
• Water quality: look at what the filter is rated to reduce and compare it with your own water report.
• Weight when full: a 15-cup pitcher is heavy to lift and pour, especially for children or anyone with limited grip.
• Care: follow the manual on rinsing a new filter, cleaning the jug and how often to change the cartridge.
