Our Product Rating System

Our Product Rating System

First, Camille (co-creator of Welpr) hand picks cleaner product options from a variety of sources.

Next, we collect information about each product's safety, consumer satisfaction, and eco-ethical standing.

Finally, we run all this information through an algorithm that calculates the Welpr Rating.

Welpr Rating:

5.0/5

The Welpr Rating takes into account 3 things:

  1. Product Safety
  2. Consumer Satisfaction
  3. Ethics & Environment
Product safety

Part 1: Product safety

We evaluate safety information from 3rd party organizations (e.g. EWG, Made Safe, etc.). Instead of relying solely on any one of these companies for safety information, we assess all of them.

Consumer satisfaction

Part 2: Consumer satisfaction

We scour the web for consumer ratings and reviews to verify products are not only cleaner options, but also effective. Products can either be Above Average, Average, or Below average for their respective category (e.g. cleaning products).

Ethics & Environment

Part 3: Ethics & Environment

When you buy a product, you’re supporting that company with your dollars. We believe it’s important to support ethical companies, so we pool together certifications that verify a company's ethics and environmental impact.

About The Author

Camille May

Hey, I’m Camille, co-creator of Welpr and your clean living guide. After selling my last company in the health food space, I went non-toxic to heal an autoimmune condition. It did wonders for my health, but navigating which products to buy wasn’t easy. We created Welpr to make that journey feel a little bit easier. When I’m not working on Welpr, you can find me at the farmers market or unwinding in the sauna, always in bed at 9pm with a good book. I live in my hometown of Austin, TX with my pit bull, Romeo.
