Pur (brand)

Pur (brand) is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Pur (brand) rather than just read about it. In short: Pur (styled PŪR; pronounced as "pure") is a division of Helen of Troy Limited that produces Pur Water products. Pur's products include water filter faucet mounts, pitchers, side taps, dispensers, coolers, and filtration systems for Kenmore refrigerators of Sears Holdings Corporation.

Key takeaways

Pur (brand) belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Pur (brand) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Pur (brand) from memory before moving on to harder problems.

Reference excerpt

Pur (styled PŪR; pronounced as "pure") is a division of Helen of Troy Limited that produces Pur Water products. Pur's products include water filter faucet mounts, pitchers, side taps, dispensers, coolers, and filtration systems for Kenmore refrigerators of Sears Holdings Corporation.

History The Pur brand was created and products invented by Minneapolis-Based Recovery Engineering, Inc., which was sold to Procter & Gamble in 1999 for approximately US$213 million. Outdoor products under the Pur brand were sold to Katadyn USA, and the Minneapolis manufacturing plant for all Pur products was closed in 2004. P&G sold Pur to Helen of Troy in January 2012 for an undisclosed amount. P&G maintained ownership of the products sold in various countries as a form of humanitarian aid under the Children's Safe Drinking Water program. These no longer use the Pur brand name.

Worked examples

Example 1 — a first encounter with Pur (brand)

Start with the simplest possible case. Write down what Pur (brand) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Pur (brand) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Pur (brand) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Pur (brand)

In research: Pur (brand) appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Pur (brand) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Pur (brand) is common in secondary-school and first-year university syllabi. It links to neighbouring topics American brands, Brand name products stubs, Helen of Troy Limited, so understanding it makes those chapters shorter.
In everyday life: Look for Pur (brand) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
