How to use FridgeBase

FridgeBase compares fridges sold on Amazon.com. This page walks you through the comparison step by step, from a one-sentence search to the link you share with someone else. Each step uses only the features described below.

Start with one sentence

In the search box, describe what you need in one sentence. An AI model turns that sentence into the comparison's filters, which you see on the page and can remove one by one. It writes no answer of its own and only handles searches about fridges.

Examples of searches the existing filters can handle:

  • a quiet fridge for a small kitchen
  • a fridge with a bottom freezer and a water dispenser
  • a large French-door fridge that fits under a cabinet
  • an ENERGY STAR fridge with the lowest energy use for its size
  • a fridge with the best price per cubic foot

If the sentence produces a filter you did not mean, remove it and adjust the rest by hand.

Answer the quiz

The quiz has 5 questions. The models that match at least half of your answers are kept and ranked from best to least match, so you can see which ones come closest to what you described.

Use the filters and their "?"

Every filter has a "?" next to it that explains what it does and what it keeps. Open it before you use a filter you are unsure about.

The filters and the sort are written into the page address. Copy the address to keep that exact view, or send it to someone else.

Sort the results

Sorting changes the order of the models on the page. Like the filters, the sort is written into the page address, so a shared link opens with the same order.

Compare up to 4 models side by side

Put up to 4 models in the comparison. They appear side by side, and the best figure in each row is highlighted. The comparison can be shared with a link.

Save models with the heart

Every product card has a heart. Use it to keep a model in your favorites list. The list stays in your browser and we never receive it.

Open a product detail panel

Open a model to see its details. The panel shows the price with the date it was collected; a model without a price is out of stock. Prices come from the product pages on Amazon.com and are updated every 7 days.

Where official data is available, the panel shows the certified annual energy use in kWh, the product class and the volumes. For ENERGY STAR models it also shows the certification, the percentage below the federal minimum and the official height and width. This data comes from the U.S. Department of Energy's Compliance Certification Database and ENERGY STAR (U.S. EPA); you can consult the database at regulations.doe.gov/certification-data.

Portable 12-volt coolers are outside these programs. Where no register lists a model, the annual figure from its EnergyGuide label on the listing is used when it is plausible for its size, and marked as such. No U.S. register gives an energy class or a noise level.

The panel also shows the cost over 10 years: today's purchase price plus annual energy use times the price per kWh times the number of years, at a constant rate. The price per kWh is $0.1816, from the U.S. Energy Information Administration, Electric Power Monthly, Table 5.6.A: average residential price, U.S. total, August 2026 (18.16 cents/kWh).

To check whether a model fits, enter the height, width and depth available in inches. The site keeps the models whose dimensions fit inside and shows the margin left. The dimensions are the official height and width for ENERGY STAR models and the ones on the Amazon.com listing otherwise. The clearance needed for ventilation and for opening the door is given in each model's manual.

A model can carry at most one badge, computed within its category: most popular (most customer reviews), top rated (best rating among the models with at least 100 customer reviews), best price per cubic foot, or most efficient (energy use for its size). Hover over the badge to see the rule.

Buy on Amazon

Links to Amazon are affiliate links: we earn a commission on a purchase, at no extra cost to you. No manufacturer pays to be listed or ranked higher.

A model enters the comparison when it reaches a minimum rating of 3.5/5 and at least 5 customer reviews on Amazon.com; stock is not a criterion. Our data comes from Amazon, the U.S. Department of Energy and ENERGY STAR. If you have a question, use the contact page.
