After reviewing the information in this guide, we continue to stand by our picks. We also added an FAQ section below.

A fireproof safe is the kind of thing you buy hoping its capabilities are never put to the test. But if the time comes, chances are, the safe will be worth far more than you paid. We’ve tested more than a dozen safes over the years, even burning five of them in a controlled fire, and we’re sure Honeywell's 1114 Lightweight Fire and Waterproof Chest is the best document safe you can get for your home or office. It's independently rated to last longer in higher-temperature fires than other safes of its size, and it will keep its contents dry longer when submerged in water. That means it has the greatest potential among document safes we’ve seen to keep your stuff—including irreplaceable documents, photos, and essentials like passports and birth certificates—secure.

It's important to note that although there are safes that offer a greater degree of fire protection, they aren't designed specifically for documents as our picks are, and they have other disadvantages. For starters, they cost at least three times as much as our top pick (and often several times more), and they weigh so much (at least 100 pounds) that they’re difficult to move once in place. Plus, according to a fire expert we spoke to, their two-hour-plus protection ratings offer diminishing returns since most house fires are out within about an hour.

The 1114 is certified to withstand high-temperature fires for twice as long as the competition, but it weighs 42 pounds and has the footprint of a mini fridge.

*At the time of publishing, the price was $120.

The Honeywell 1114 Lightweight Fire and Waterproof Chest is independently verified by the safety organization Intertek to keep personal items safe during a fire for up to an hour—twice as long as the competition—in conditions as hot as 1,700 °F. A house fire can peak at about 2,000 °F, but this kind of heat occurs at the highest points in your home, namely the attic or at least the ceiling. It’ll be cooler down near the floor, where you keep your safe. Honeywell also says the safe will keep spray and flood water out for 100 hours. It's large enough to hold both letter- and legal-size sheets of paper without your having to fold them. The additional protection makes the 1114 noticeably larger and heavier than other safes of similar capacities—it weighs 42 pounds and takes up the same amount of floor space as a mini fridge. But we think the price and size are worth tolerating because this safe gives your stuff a greater chance of surviving a disaster.

Measurements: 20 by 17.2 by 7.3 inches (WDH)Weight: 42 poundsIntertek ETL fireproof rating: one hour at 1,700 °F

This model is the most affordable safe of its size, and it's rated to last as long in a fire as anything else in its price range.

Larry McKenna, a fire protection engineer at the US Fire Administration, told us you should "get the best [safe] you can afford." The Union Safe Company Waterproof And Fire Rated Document Safe, sold exclusively at Harbor Freight, is the best option if you can't spend $100 on a safe or if you have limited floor space. It's large enough to hold 8.5-by-11-inch sheets of paper without the edges curling, and it's rated to withstand a 1,550 °F fire for 30 minutes. That's half the endurance and a significant reduction in temperature protection compared with our top pick, so choosing this safe means you’re at greater risk of losing the contents if disaster strikes. But every fire is different, and this safe is certainly better than no safe at all. On the plus side, it has a much smaller footprint than the Honeywell and weighs only 28 pounds, so it's easier to move if necessary. Just be careful with the keys: Unlike every other brand whose safes we tested, Union Safe explicitly says it can't replace lost keys.

Large enough to hold hanging folders and tough enough to last up to an hour in a fire, at 80 pounds the 1108 weighs twice as much as the Honeywell 1114.

*At the time of publishing, the price was $160.

The Honeywell 1108 Fire/Water Large File Chest is a larger version of our top-pick safe, with the same one-hour fireproof rating. This 84-pound behemoth is designed to hold both letter- and legal-size hanging file folders, which is convenient if you have a lot of documents or simply want to keep your things organized. But it is a huge hassle to move.

Measurements: 20.1 by 16.9 by 13.4 inches (WDH)Weight: 84 poundsIntertek ETL fireproof rating: one hour at 1,700 °F

The 2037F is large enough to hold file folders and documents, but it has only a 30-minute burn rating. We recommend it only if you’re looking to save a little money or don't have the space for a giant safe.

*At the time of publishing, the price was $84.

The First Alert 2037F Water and Fire Protector File Chest is the most affordable model designed to hold letter-size hanging file folders. It has a 30-minute fireproof rating, and over years of testing this category, we’ve been impressed with First Alert's safes due to their reliably solid build quality and affordable prices for the level of protection they offer. Unfortunately, many of them have been discontinued, so be sure to grab the 2037F if it interests you.

Nick Guy worked with fire professionals to accurately simulate a house fire and learn how safes perform in real fires. His father and grandfather are both volunteer firefighters with 80 years of combined experience. Together, the three designed, built, and burned a testing rig that approximated a house fire as closely as possible. Guy also interviewed John Drengenberg of UL to understand what the certifying body is looking for when it tests safes, and spoke to Larry McKenna, a fire protection engineer at the US Fire Administration, who explained how hot fires get and how long they can last.

Document safes are meant to provide protection from fire, water, and (to a degree) theft for people who wish to keep important belongings secure in an office or at home. They’re best for hard-to-replace or valuable documents—such as passports and birth certificates—or small items like hard drives or USB sticks. Most people can find good use for a fireproof safe, whether they want to be ready for travel or major financial transactions, or if they just want to add an extra layer of safety for a drive full of treasured digital photos.

Safes trap humidity, so it's important to air them out on a regular basis, and some manufacturers recommend keeping important items, including jewelry, sealed in airtight containers.

Fireproof safes are not meant to be burglarproof or to serve as impenetrable time capsules. If you have jewelry, precious metals, or anything else of high value that you don't need frequent access to, consider a safe that is anchored to your floor, or even a safe-deposit box at a local bank. It isn't nearly as easy for a thief to get into a bank vault as it is for them to enter your house. These document safes are also not gun safes and should not be used as such.

Safes trap humidity, so it's important to air them out on a regular basis, and some manufacturers recommend keeping important items, including jewelry, sealed in airtight containers. We address this issue further in the Care and maintenance section below.

For this guide, we didn't look for expensive professional installations or gun safes but rather smaller, fireproof safes that fit under a desk or in a closet. This is the kind that's heavy and secure but still ready to be lifted and moved if necessary. A document safe needs to be fireproof and watertight (so "floodproof," too), with a locking mechanism that keeps opportunistic intruders out.

Three major brands—First Alert, Honeywell, and SentrySafe—make most of the fireproof safes you’ll find for home use, and there are a few others with smaller selections. Here's what we looked for when deciding which models to test and pick:

We trust UL and Intertek's testing procedures, but for our initial round of testing in 2016 we wanted to see for ourselves how our safe finalists (First Alert's since-discontinued 2030F and 2603DF, SentrySafe's CHW30100 and FHW40200, and Honeywell's 1106) stood up to a house fire and what they looked like afterward. So, with the help of trained fire professionals, we built a 4-by-8-foot room out of plywood and two-by-fours, and we installed drywall inside to radiate heat. Then we filled it with flammable couch cushions, a carpet, cardboard, and some wood, put the safes in (video), and lit it (video).

We should note that this test was not an attempt at total destruction. We were looking for success, not failure. A safe could have failed for any number of reasons unrelated to its construction, such as how firefighters handled it. In this test, a safe that protected its contents proved that it was up to the task.

We filled each safe with the same contents: five printed photos in an envelope, a newspaper, a flash drive with various video files, and a DVD with a movie file burned to it. Within minutes, the fire was up to about 1,300 °F. We let it run its course for about half an hour before asking firefighters to put it out with a fire hose. When the safes (or what remained of them) were cool to the touch, we opened them to check out the aftermath, including if any water from the fire hose had seeped through. We also examined the safes’ overall build quality, including checking the body for obvious weak points and seeing if any pieces broke during normal use, and we considered their size and weight while attempting to carry them.

In subsequent rounds of testing, we didn't subject safes to the same fire-box test, but we did use what we learned from the 2016 burn to inform our picks. The safes’ fireproof ratings—which we found to be totally accurate last time—and physical build quality have determined our more recent recommendations. We lifted the safes, loaded them with paper and folders, and looked for weak points such as cracks or parts that might break off. As we examined them, some of the safes literally fell apart. We also tried to submerge them in a bathtub to test if water would seep through, but, well, safes float.

In 2021, we tested Honeywell's 1114, 1503, and 1553; SureSeal by FireKing's SS104 and SS106; and the Union Safe Company Waterproof And Fire Rated Document Safe (sold by Harbor Freight).

The 1114 is certified to withstand high-temperature fires for twice as long as the competition, but it weighs 42 pounds and has the footprint of a mini fridge.

*At the time of publishing, the price was $120.

The best fireproof document safe to protect belongings from fire and water is the Honeywell 1114 Lightweight Fire and Waterproof Chest. It can survive hotter fires for longer than any other home or office document safe we’ve found from a reputable brand, and Honeywell claims that this safe should keep water out for 100 hours. Its interior is long enough and wide enough that you should be able to fit documents of any standard size, including letter, A4, and legal. (If you need to store hanging file folders, see our also-great picks, the Honeywell 1108 and First Alert 2037F.) Thoughtful design features such as a securely attached lid, plus hydraulic hinges that prevent your fingers from getting crushed when you close it, set it apart from the competition.

Intertek rates the Honeywell 1114 to withstand temperatures of up to 1,700 °F for an hour while keeping the internal temperature under 350 °F. That's superior to the 1,550 °F and 30 minutes most other safes (including our budget pick) are rated for, and though it's not a guarantee of security, the rating means the 1114 should keep more of your stuff protected in more situations. According to Larry McKenna of the US Fire Administration, a room will remain on fire for about an hour to an hour and 15 minutes if it's not otherwise put out, and temperatures can reach up to 2,000 °F. McKenna says that since heat rises, those higher temperatures will be at the top of the room, and it’ll be cooler down where safes are usually kept, so the protection the 1114 offers will likely be enough in many circumstances. (Again, every fire is different, and there's no guarantee.)

Additionally, Honeywell promises digital-media protection, as well as waterproofing under a meter of water for up to 100 hours. However, those two claims are based on Honeywell's own testing, not the work of a third party like Intertek.

We appreciate the lid's hinge system, which stops the heavy lid from potentially crushing your fingers as it closes. It's still possible to slam the lid shut, but if it's knocked down accidentally, it’ll slow down a few inches from closing. In our testing, we’ve seen this feature only on larger safes from Honeywell, not on any other brand's models. Additionally, this Honeywell safe has latches on either side of the lock that provide an extra degree of security in keeping the lid shut.

The 1114 has an internal capacity of 0.39 cubic feet, with the interior measuring 14.8 inches wide by 12 inches long by 3.8 inches tall. That makes it shorter, but wider and longer, than most document safes. It's large enough to hold unfolded sheets of paper.

Honeywell offers a seven-year manufacturer's warranty on the 1114—an improvement over the five-year warranty that accompanies our runner-up safe. Honeywell also promises a "lifetime after-fire replacement guarantee." If your safe is damaged in a fire at any time, the company will replace it (but, important to note, not the contents) for free with the same or a similar model.

With a footprint 20 inches wide and 17 inches long (about the same as a mini fridge), the 1114 may not be a great fit in small apartments or other living situations where there's not a lot of floor space. With its size and higher fireproof rating comes weight, as well: Moving this 42-pound safe around isn't as easy as moving a smaller, less protective option. You might see that as a good thing if you consider it through the lens of both fire and theft protection, but the 1114's heft can be inconvenient if you have to move the safe around when you need access to your stuff.

The 1114 lacks a digital keypad, a feature that, though not essential, would offer a way to get into the safe without a key. None of our other current picks offer a keypad, either, but it's something we keep an eye out for since we’ve found it to be a convenient alternative to a physical key.

This model is the most affordable safe of its size, and it's rated to last as long in a fire as anything else in its price range.

The Union Safe Company Waterproof And Fire Rated Document Safe is a good alternative if our top pick is out of stock, if you are on a tighter budget, or if you have less floor space. The safe, sold exclusively by Harbor Freight, has a lower UL certification than our main pick, the Honeywell 1114: 1,550 °F for 30 minutes versus 1,700 °F for 60 minutes. That's still pretty good, as house fires often burn within this temperature range, and firefighters in many areas of the US are able to respond within minutes. But although this safe will ably protect your valuable documents in many fire situations, we’ve concluded that a higher degree of protection is worth spending more for, if you can afford it.

Union Safe Company says its safe is designed to keep out water for 24 hours during full submersion—significantly less than the 100 hours Honeywell promises for our top pick, but still quite good. Though this safe may not survive an extensive flood, it should at least keep out any water used to extinguish a fire.

Unlike the Honeywell 1114, this safe doesn't have latches to keep it shut, but its double-locking mechanism feels secure. You have to turn the tubular key and then the knob around the keyhole to open or fully lock the safe. This step allows you to move the safe around without worrying about the lid popping open, even when it's unlocked.

Union Safe Company's offering has less storage space than our top pick. It's still large enough to fit an unfolded sheet of letter-size paper, but it has a much smaller footprint, as due to its 17.3-by-14.6-inch dimensions it takes up only about 73% of the floor space that the Honeywell does (1.75 square feet compared with 2.4 square feet). This budget option is also much lighter, weighing only 28 pounds to the Honeywell 1114's 42 pounds, and it has a handle that makes it easier to carry.

The major downside to this safe is that Union Safe Company does not provide replacement keys if you misplace yours—a sticker on the front of the safe warns buyers of this contingency. Although that won't be a problem for most people most of the time, it could be a big headache if you lose your keys.

Large enough to hold hanging folders and tough enough to last up to an hour in a fire, at 80 pounds the 1108 weighs twice as much as the Honeywell 1114.

*At the time of publishing, the price was $160.

If you have a lot of documents and want to organize them in folders, the Honeywell 1108 Fire/Water Large File Chest is the best choice. It has all of the same attributes as our main pick, the Honeywell 1114, including the ability to survive a fire at up to 1,700 ºF for an hour. The main difference between the two is the 1108's ability to accommodate both letter- and legal-size hanging file folders within more than a cubic foot of storage space. The result of that extra space is that the 1108 is the heaviest safe we’ve tested, weighing more than 80 pounds. That makes it tough to move around even with the small grips carved out along its outer edges.

*At the time of publishing, the price was $84.

If you need to store hanging file folders and don't want to spend more than $100 on a safe, the First Alert 2037F Water and Fire Protector File Chest is a good choice. With a 0.62-cubic-foot capacity, it's large enough to hold letter-size, but not legal-size, folders. It has the same ratings and characteristics we’ve observed over years of testing—namely, great build quality and affordable pricing compared with the competition—that have made First Alert's safes such strong contenders when they’re available. (Many have been discontinued over the years we’ve been updating this guide.) Compared with the Honeywell safes, this model is not rated to last as long in a fire, but it's still certified to withstand fires at temperatures up to 1,550 °F for 30 minutes. It's also smaller, lighter, and easier to move around—just 16.25 by 13.25 inches and 38.9 pounds—and less expensive.

Humidity can be an issue with these safes, as they tend to capture and hold in moisture, which can damage the contents. It's a problem that multiple safe companies mention in their documentation and other materials.

First Alert's safes have stickers that read, "[Be] sure to place important paper documents, currency, jewelry, and other delicate items in an airtight, dishwasher-safe container." The company says to ventilate the safe by opening it for 20 minutes every two weeks. SentrySafe offers a similar warning, suggesting an airtight container for "jewelry with working parts, watches, stamps, or photos." It also specifically says not to keep pearls in its safes. Honeywell's instruction booklet says to air its safes out once a week for 30 minutes.

Humidity varies in different regions and seasons, of course, but we recommend following the manufacturers’ instructions. Set a reminder (say, a recurring calendar event) to check on the contents of your safe every two weeks to see how humidity is affecting its contents. Every safe we’ve tested has come with a large silica-gel packet inside, and though none of the instructions we’ve read specifically mention leaving the packet there as a solution to the moisture issue, it's worth doing so to help regulate the humidity, along with taking the other recommended steps.

If the Honeywell 1114 goes out of stock or jumps in price, go with the SureSeal by FireKing SS104 is physically identical to the Honeywell 1114 other than the color of the branding on the front. They’re the same safe. The SS104 was more expensive than the 1114 at the time of our research, and it went out of stock while we were writing this guide. If it's back in stock and less expensive than the Honeywell 1114 when you’re shopping, pick it instead.

If the Honeywell 1108 goes out of stock or jumps in price, and you’re OK with letter-size storage, choose the SureSeal by FireKing SS106. This is a smaller alternative to the Honeywell 1108 that can hold letter-size folders, but not legal-size.

Honeywell's 1104 is our former top pick. It's the same size and shape as the 1114, but it usually costs more and is rated to keep the contents dry for only 24 hours, versus 100 hours for our current pick.

Honeywell's 1103, 1503, 1533, and 1553 are all variants of the same model with different latches and locks. Although they’re generally strong contenders, their interior dimensions are slightly too small to hold an 8.5-by-11-inch sheet flat, and at this writing they cost more than our budget pick from Union Safe Company.

The SureSeal by FireKing SS1103 is a smaller version of the SS104 (and therefore the Honeywell 1114). It's expensive for its 30-minute fire rating, and stock was inconsistent when we were researching the category.

We’ve seen generally good construction across the First Alert product line for the past several years. All of the safes are rated for 30 minutes at 1,550 °F, built with the same great design, and relatively affordable. Unfortunately, the company has discontinued many of its safe models over the years we’ve been maintaining this guide. For example, we previously recommended the 2030F, and we stand by it as a great safe—if you can get it. The smaller 2017F and the 2602DF, a former budget pick, are no longer being made. If you can find a First Alert safe in a size that works for you at a price you’re willing to pay, it's likely a good bet. We just can't be confident enough in the stock to recommend all models.

We’ve had too many problems with safes from SentrySafe over the years we’ve been working on this guide to be able to recommend any of its models. The CHW30100, for example, has a locking mechanism installed on a plastic faceplate that you can pry off by hand—without much force, the whole mechanism can pop off in your hands when the safe is open. Although we didn't test the safes extensively for theft protection, this isn't a reassuring sign of design quality.

The CHW30100 also let water in during our burn-room test. As we mentioned earlier, it's possible that damage from handling could have occurred, but in this specific test, this model failed. Though we would’ve dismissed it anyway because of its faceplate, this performance shortcoming only cemented our decision.

The SentrySafe HD2100 and CFW20201 both have the same design flaw. Their lids are attached only by small nubs on either side of the hinge, and the material is pliable enough that you can actually break the lid off, with less force than you might anticipate. You should expect a certain degree of build quality from something that's going to house your most important documents, and these safes do not deliver. As for other SentrySafe models, although we didn't test them, the CHW20101, CHW20201, and CHW20121 are all variants on the same design, so we wouldn't expect different performance. Additionally, the first of two HD2100 units we tested arrived with cracks in its body. SentrySafe representatives told us the company recently had manufacturing problems that could have resulted in this issue, and that it has since switched back to its prior system, which should prevent this issue from happening.

The SentrySafe SFW082F features a battery-operated keypad, but the manufacturer recommends only using high-quality, non-rechargeable batteries with an 8 to 10 year lifespan. We worried about being unable to retrieve valuables from a safe with a temperamental design—especially if a fire or flood were to occur—and decided not to test this model.

The SentrySafe Hd4100Cg claims to keep documents safe even when fully submerged for up to 72 hours, but our Honeywell 1114 pick handily outdoes it, keeping water out for up to 100 hours.

The SentrySafe Sfw123Dsb, meanwhile, costs twice as much as our main pick, but is only certified to keep up to 8 inches of water out for 24 hours.

The AmazonBasics Security Safe Box comes in sizes ranging from 0.5 to 1.2 cubic feet. But unlike the models we tested, it is not fireproof or waterproof. Though it may keep unwanted hands off your important documents, it won't protect anything if disaster hits.

SereneLife's SLSFE14 was the top seller in the "wall safes" category at the time we looked in early 2020, but it's only heatproof, not fireproof or waterproof.

The Honeywell 1106 is much more expensive than our budget file-folder pick, without the longer fire-resistant benefits of our top file-folder safe.

SentrySafe's FHW40200 exhibited the same faults as the CHW30100. Its faceplate came right off with a tug, and water damaged the contents in our fire test.

We can't recommend the SentrySafe HD4100. Even though it has a more solid fit and finish than other safes we’ve tested from the company, the issues we’ve seen are so widespread and serious that we’re reluctant to suggest any of SentrySafe's models.

Some document safes aren't fireproof, as they’re only marketed to securely lock up your valuables. If you want a safe that’ll keep out the flames, look for one that's been tested and rated by UL and by the inspection firm Intertek, which uses the "ETL" mark. These fireproof safes aren't totally fireproof, though; instead, they’re designed to resist a certain degree of heat for a specified amount of time. For example, Intertek rates our top pick, the Honeywell 1114, to withstand temperatures of up to 1,700 °F for an hour while keeping the internal temperature under 350 °F. (Paper documents will generally ignite at around 424 to 475 °F.)

UL and Intertek, two organizations that test and rate fireproofing, don't test how waterproof safes are. Wirecutter relies on the manufactuers’ claims about their safes’ ability to keep water out. We’ve tried to independently verify these claims by spraying them with a fire hose and attempting (unsuccessfully) to submerge them in a bathtub. So far, none of our picks have allowed water inside. If you’re concerned about waterproofing, you can keep delicate valuables like irreplaceable documents and jewelry in an airtight container inside the safe.

Safes trap humidity, which can cause mold. To avoid mold damage, many safe manufacturers recommend airing out their safes for 30 minutes every week. It's also a good idea to place important items, like jewelry, in airtight containers within the safe.

The 4 Best Fireproof Document Safes of 2023
