Between exaggerated marketing claims and unreliable online reviews, it’s tough to know whether a purchase is going to live up to its lofty promises. That’s where the Good Housekeeping Institute comes in.
Since 1900, our powerhouse team of on-staff scientific experts—including engineers, fiber scientists, data analysts, researchers, registered dietitians, chemists, and seasoned product evaluators—has thoroughly assessed the products you use in your daily life so you can rest assured you’re not wasting money on duds or updates you simply don’t need.
Who We Are—and Why You Should Trust Us
When the Good Housekeeping Institute opened its “experiment station” to evaluate consumer products in 1900, it was six years ahead of the FDA and 14 years ahead of the FTC in consumer protection. For more than 125 years we’ve been ahead of the curve, reporting on the potential dangers of sugar decades before the groundbreaking cover story in the New York Times Magazine and banning cigarette ads 12 years in advance of the Surgeon General’s warning’s appearance on cigarette packs.
In fact, the members of the Good Housekeeping staff and the Good Housekeeping Institute experts have charged themselves with advocating for consumer safety and protection and savvy shopping since the magazine’s earliest days: Our first issue in 1885 stated that the mission of Good Housekeeping would be “equal parts public duty and public enterprise.”
Today the Good Housekeeping Institute continues to earn the trust of consumers all over the globe, but with so much new technology and equipment, its modern incarnation is a far cry from the original “experiment station.” At present, the Good Housekeeping Institute is a state-of-the-art 18,000-square-foot product testing facility in the LEED Platinum–certified Hearst Tower in the heart of Manhattan. Our uncompromising and extensive lab and consumer testing process employs unique, proprietary scientific evaluation, no matter what product is being tested.
In addition to conducting tests with consumers to get real-world feedback, our experts evaluate thousands of products each year in our cutting-edge labs. The Good Housekeeping Institute is made up of seven distinct labs: the Beauty & Personal Care Lab, the Textiles, Apparel & Paper Lab, the Kitchen & Cooking Lab, the Home Care & Cleaning Lab, the Home Improvement & Outdoor Lab, the Tech & Engineering Lab, and the Nutrition & Fitness Lab. Each lab is staffed by experts in their respective fields who have had years of experience in laboratories, clinical settings, product-development fields, professional kitchens, and more.
Each lab’s exhaustive analysis is key to the unrivaled trust that consumers have in the Good Housekeeping brand and the Good Housekeeping Seal, the most recognized consumer emblem in the U.S. for more than 115 years. We continue to test products meticulously so you can make the best decision for you, your home, and your family.

How the GH Institute Labs Test
Our evaluations combine lab and consumer testing, allowing us to review products both comparatively in controlled settings and with feedback from real people in their everyday lives. Both processes follow standard protocols tailored to each specific product test, ensuring that our data is as objective as possible.
Our New York City–based team methodically evaluates all the latest appliances, beauty essentials, home furnishings, and more for performance, durability, ease of use, safety, and value using industry-standard and proprietary testing methods. When we put products to the test in our labs, we evaluate quality claims to make sure the products can stand up to any conditions they might encounter. Then we send the items out to a consumer testing panel to get feedback on how they perform outside of our labs.
Here’s more on just how rigorously we test products in each of our seven testing spaces within the Good Housekeeping Institute:
Textiles, Apparel & Paper Lab
In this lab, often simply called the “Textiles Lab,” our textiles experts evaluate fiber- and paper-based products from bedding, clothing, and footwear to luggage, bath towels, and disposable items such as toilet paper, diapers, and period products. Fabrics are tested for strength, pilling, and abrasion in a climate-controlled room and are also tested for stretch recovery, absorbency, and flammability. We put clothing through colorfastness tests to see if it will fade or bleed and grade it in a special room with standard lighting. Garments and bedding also go through repeated laundering in standardized washers and dryers to assess shrinkage, after-wash appearance, and wrinkle resistance. Activewear and cooling materials are tested for moisture management, and our unique rain tester simulates downpours to measure water resistance.
When it comes to all things travel, our textiles pros have the answers. For luggage and travel bags, we first measure each bag’s size, weight, and capacity to see whether it can actually fit reasonable loads for various trips. We then simulate wear and tear and test durability by conducting abrasion-resistance, scratch-resistance, and water-resistance tests—and then we drop-test each bag using specialized lab equipment. For parenting products such as diapers, we test absorbency from all angles, checking how quickly each absorbs liquid and how well it holds on to fluid in its core to prevent leaks.
We also rely on consumer testing, both in the lab and at home. Testers rate the softness of things like sheets, towels, and toilet paper in a blind comparison. In addition, we solicit feedback from consumer testers who wheel loaded luggage through an obstacle course to rate maneuverability, handle comfort, and wheel performance in simulated real-life experiences. We send samples of bedding, workout gear, bras, and more for testers to try out in their home routines and rate on aspects including comfort, support, breathability, softness, and more. Our tester panel then gives us in-depth reviews on their experiences, often resulting in hundreds of thousands of data points.
Kitchen & Cooking Lab
This lab—sometimes called just the “Kitchen Lab”—works with every product that comes in contact with food for storage or preparation, including countertop gadgets, cookware and utensils, and large and small appliances (for both indoors and outdoors). The product experts here are a mix of professionally trained chefs, nationally published recipe developers, food stylists, and kitchen appliance product developers. Our goal: to help readers feel more confident in the kitchen and make educated decisions about what goes on (and in!) their counters. When we test, we keep the home cook at the top of our minds–what will the average use case be, how well does the product work, is it easy to use and clean, and—most important—is it worth the effort, space, and money it requires?
Our scoring process is based on both quantitative and qualitative criteria: We take measurements using sophisticated instrumentation such as thermocouples to log how quickly water boils, the temperature at which a coffee maker brews, and how consistently a refrigerator holds temperature. We also assess the most important factor when it comes to kitchen appliances: How do the results taste? To be as objective as possible, we back up the decisions of our taste buds with quantitative measurements, such as of how much of a blended smoothie is able to pass through a specific sieve or how crisp air-fried chicken wings are. We tally all these data points and use our expertise to make the best recommendations for every type of home cook.
Home Care & Cleaning Lab
Responsible for evaluating anything used to clean clothing, fabric, flooring, and everything else around the home, this lab (”the Cleaning Lab” for short) tests major appliances, small appliances, soaps, disinfectants, detergents, stain removers, and cleaning tools and equipment. To test performance, safety, ease of use, and other attributes, we follow industry-standard procedures and use our proprietary methods. We apply our own stains to fabrics, dishes, test flooring, wall panels, and carpeting to simulate the cleaning issues and challenges of a real home and evaluate the cleaning performance and safety of the products we are testing in a controlled comparative setting. All cleaning products and formulas are reviewed for ingredient safety and thoroughness, accuracy, and clarity of the labeling.
When it comes to major appliances, we use a system to monitor water and energy use, and we even produce our own water to test cleaning products with different water-hardness conditions. Washing machines and clothes dryers are tested for how well they clean or dry, how gentle they are on fabrics, and how easy they are to use. Dishwashers get checked for cleaning and drying performance, capacity, ease of loading, and more. Vacuums are evaluated with an automated tester that follows an industry-standard procedure to measure the amount of embedded dirt each can remove, with each vacuum tested exactly the same way in our temperature- and humidity-controlled room. We also evaluate sound, suction, and bare-floor and pet-hair cleaning performance and have consumers road test each vacuum for maneuverability and ease of use. All this cleaning, testing, and product knowledge is turned into the most up-to-date, helpful, time-saving, and ingenious household cleaning tips and advice.
Home Improvement & Outdoor Lab
Our home improvement pros test anything and everything you’d need for home updates, build-outs, improvements and maintenance. We vet products from the outside of the home in, evaluating the efficiency, durability, and overall performance of windows, siding, roofing, and doors using equipment like our standardized drop tester, Taber for abrasion, and a UV machine to simulate accelerated weathering. Home comfort is also an important category for this lab, which tests humidifiers, dehumidifiers, air purifiers, window ACs, and other small appliances that you may need for your home even without a major renovation.
We also test heating, ventilation and air conditioning (HVAC) systems by assessing ease of use and road testing for efficacy while reviewing industry-standard data sets. We evaluate flooring and interior paint with tests around ease of use, quality, and durability, including testing for fade resistance using a UV accelerated weather machine and scratch resistance using a Taber to measure abrasion. Last, we assess these finishes’ ability to resist stains—and how easy they are to clean or restore once damage does happen.
Seasonal needs play a big role in this lab. From the best ways to keep your home free of insects and other pests to lawn care to keep weeds at bay, to leaf blowers, snow blowers, and other outdoor-maintenance essentials, we test the products that help ensure that you’ll be prepared for whatever comes your way.
Beauty & Personal Care Lab
The chemists in the Beauty & Personal Care Lab carefully evaluate beauty, haircare, skincare, and oral care products to find the ones that actually work. We work with a broad panel of consumer testers for real-life feedback on product performance, and in the lab we use state-of-the-art instruments to gauge performance—including a Corneometer, which measures skin’s moisture levels to track skincare’s hydration efficacy, and our Visia Complexion Analyzer, a digital-imaging device that can track changes in skin, including the intensity of wrinkles, pore size, dark spots, and color coverage of cosmetics.
In haircare testing, GH scientists use an Instron machine, which gauges a product's conditioning capacity, and a swatch-washing station to calculate a product’s ability to cleanse or protect against color fade. We also have weathering procedures to mimic hair exposure to UV light and heat styling and an environmental chamber to expose hair to high levels of humidity to test frizz-fighting claims.
Nutrition & Fitness Lab
The GH Nutrition Lab aims to provide evidence-based nutrition recommendations to help demystify food labels and help shoppers make informed nutrition choices and feel confident navigating the aisles of grocery stores. Our food and diet recommendations are centered on health-based, realistic eating advice from our in-house registered dietitian, who investigates nutrition trends and news as well as diets to find the safest, most effective recommendations for most people.
When we test food products, we vet them first based on nutritional criteria and taste, but we also consider simplicity, convenience, and transparency to make our recommendations. This lab helps to circulate smart, consumer-focused food, fitness, and dietary recommendations that meet at the intersection of flavor and nutrition to help people live their healthiest, most balanced lives. We also review supplements and vitamins, giving guidance and tips on how to incorporate these products safely into their everyday lives.
This Lab, overseen by a certified personal trainer, also covers fitness products and services with the understanding that nutrition and fitness go hand in hand to support a healthy lifestyle. Equipment is tested for functionality, durability, ease of use, and more. We also review assembly, features, maintenance requirements, and other factors to ensure that we’re recommending products consumers will continue to use.
Tech & Engineering Lab
This lab is made up of engineers and tech analysts who are responsible for evaluating electronic gadgets and equipment including TVs, phones, and headphones,as well as the latest innovations in smart-home technology. They also oversee testing of parenting and pet products that benefit from the assessment of an engineer, including toys, baby monitors, strollers, cribs, and more. In fact, we spend all year testing toys (with the help of kid testers!) to find the best options for every age and interest. We even have a handheld machine that tests whether products contain concerning elements like lead.
We use a decibel meter to measure the sound output of home appliances, a Kill-A-Watt to measure how much electricity an item that gets plugged in uses, an infrared camera to see heat distribution, and a force gauge to measure how easy it is to knock something over. These are just some of the many devices we keep in our lab, and we also have our consumer testers weigh in with their feedback on performance.

FAQs About the Good Housekeeping Institute
How do you choose which products to test?
Our experts stay closely connected with their industries, attending trade shows and conferences to learn about new launches and innovations. They also review product pitches from brands and monitor market research to understand best sellers, emerging trends, and what consumers are actively searching for. While we consider input from manufacturers and brand representatives, our lab analysts ultimately decide which products to test based on relevance, performance claims, consumer interest, and category needs.
For the Good Housekeeping Seal and Good Housekeeping Awards programs, brands may pay a submission fee to have a product evaluated. These fees cover only the cost of testing and do not influence our results or whether a product is recommended.
How is the Good Housekeeping Institute different from other review sites?
For more than 125 years, Good Housekeeping has been evaluating products and advocating for consumers. In fact, the Good Housekeeping Institute was established before federal agencies like the FDA and FTC existed, helping readers understand which products were worth their investment and how to use them safely and effectively at home. Today that mission continues with modern scientific rigor. When we say that we tested a product, we don’t just mean we tried it. Our on-staff experts—including chemists, engineers, fiber scientists, registered dietitians, culinary professionals, and other seasoned pros—evaluate products in their Labs using standardized testing methods designed to generate reliable, repeatable data.
We also incorporate consumer testing to understand how products perform in real-world conditions. Attributes like comfort, ease of use, and fit are best evaluated by people, not just equipment, so we combine lab data with user feedback for a holistic view of performance.
Finally, we don’t simply publish scores or specs. Our editors and analysts interpret the data to explain who a product is best for, how it compares to alternatives, and how it fits into everyday life so you can make an informed decision.
How is the consumer testing handled?
Consumer testing is an important part of our evaluation process and is designed to reflect real-world use. In some cases we invite local testers to the Hearst Tower in New York City, particularly when in-person participation is required. For example, beauty products may involve clinical measurements of skin, and footwear testing may require fit verification before wear testing begins. Certain evaluations, such as blinded softness comparisons or taste tests, may also take place directly in our Labs.
In most cases, however, products are shipped to testers nationwide so they can use them in their everyday environments. In recent years, many of our consumer testers have been recruited from our GH+ membership community, meaning that Good Housekeeping readers themselves help evaluate products.
To participate, testers complete detailed screening questionnaires specific to each study. This allows our analysts to match products with participants who are best suited to evaluate them. For example, in toy testing, parents share information about their children’s ages, interests, and play preferences. For luggage testing, participants provide details about their upcoming travel plans, including destination and mode of transportation.
Testers receive detailed instructions outlining how to evaluate each product over a defined time period. After testing, they complete structured surveys that include both quantitative ratings and qualitative feedback. By combining carefully screened participants with clear protocols and standardized reporting, we ensure that consumer insights are meaningful, relevant, and reflective of real-life use.
How long does product testing take?
The length of testing varies by category and product type. Some evaluations take four to six weeks, while others may span several months. Most consumer testing is conducted over a two- to four-week period, which allows participants to use products in real-life conditions while still ensuring timely reporting. Shorter assessments, such as snack taste tests, may be completed within days. For products like mattresses and appliances, we often assess performance over extended periods to better understand durability and long-term use.
When a new or trending product enters the market, our experts may also provide early analysis based on initial evaluations. Because our analysts are trained in their respective fields and follow established testing protocols, they can assess key indicators such as materials, ingredients, construction, and design to offer informed preliminary insights. These early impressions are clearly distinguished from longer-term Lab and consumer testing results.
What happens to products when you're finished testing them?
It depends on the type of testing involved. In many cases consumer testers are allowed to keep the products they evaluate after the initial testing period. We may also follow up with them to gather insights about long-term performance and durability.
For products tested in our Labs, items that remain in new or like-new condition are often shared with consumer testers for extended use or donated to local charities. This is especially common for baby and children’s products such as toys, strollers, car seats, and diapers.
Some products are altered or destroyed during testing—for example, fabrics may be marked up for measurements or cut into swatches for mechanical testing. When items cannot be reused, we make efforts to recycle materials responsibly and partner with recycling organizations whenever possible.
Ultimately, our goal is to handle products thoughtfully and minimize waste while maintaining the integrity of our testing process.
Are brands allowed to see the results before you publish them?
No. Our testing is conducted for editorial purposes to support our readers. Brands do not receive access to our results prior to publication.
As part of our editorial standards, we may fact-check product specifications or claims with manufacturers to ensure accuracy. If our testing uncovers a potential safety concern or a significant issue, we contact the brand for comment before publishing. However, brands do not influence our findings, conclusions, or recommendations.
What does it mean when a product earns the Good Housekeeping Seal?
The Good Housekeeping Seal has been a symbol of quality and trust since 1909. When a product earns the Seal, it has been evaluated by scientists and experts at the Good Housekeeping Institute and found to perform as promised.
Not every product that applies earns the GH Seal. Our analysts rigorously review eligible products to ensure that they meet our standards for quality, performance, and safety and that they deliver on the claims made on packaging and in advertising. In short, a product must perform as a consumer would reasonably expect it to and meet its stated claims.
Products that bear the Good Housekeeping Seal are also backed by our two-year limited warranty. If a GH Seal-bearing product is found to be defective within two years of purchase from an authorized retailer, Good Housekeeping—not the manufacturer!—will refund the purchase price (up to $2,000) or, at our discretion, repair or replace the product. If you believe you have purchased a defective product covered by the GH Seal warranty, please email [email protected].
Ultimately, the GH Seal represents our commitment to stand behind the products that earn it and remains one of the most recognized consumer emblems in the U.S.
