A good first aid kit for most homes holds what the American Red Cross lists for a family of four: dressings in several sizes, tape, antiseptic wipes, antibiotic and hydrocortisone ointment, gloves, a breathing barrier, an emergency blanket, a thermometer, tweezers, and printed instructions. Buy the case that matches where it will live (house, car, trail, or job site), then add your own medication. Target, Walgreens, REI, Amazon, and the makers themselves all sell them; the differences are in what is inside, not the price tag.

What Belongs Inside: A Family List Next to the Workplace Standard
Two published lists settle most arguments about contents. The American Red Cross, the US humanitarian group that also teaches first aid and CPR, publishes its family-of-four list. ANSI/ISEA Z308.1-2021, the workplace standard written by the International Safety Equipment Association and approved by the American National Standards Institute, sets minimums for two classes of job-site kits. The Mayo Clinic also publishes a contents checklist worth printing before you shop.
| Item | Family of four | ANSI Class A | ANSI Class B |
|---|---|---|---|
| Adhesive bandages | 25, assorted | 16 | 50 |
| Sterile gauze pads | 5 (3×3 in) + 5 (4×4 in) | 2 (3×3 in) | 4 (3×3 in) |
| Antibiotic ointment | 5 packets | 10 applications | 25 applications |
| Antiseptic wipes | 5 packets | 10 | 50 |
| Gloves (pairs) | 2, nonlatex | 2 | 4 |
| Emergency or foil blanket | 1 | 1 | 1 |
| CPR breathing barrier | 1, one-way valve | 1 | 1 |
| Splint and tourniquet | Not listed | Not required | 1 each |
| Aspirin | 2 packets, 81 mg | Not listed | Not listed |
That family list also includes adhesive cloth tape, an instant cold compress, two hydrocortisone packets, two roller bandages, two triangular bandages, a non-glass oral thermometer, tweezers, and emergency first aid instructions. Class A kits, per the standard, handle the most common workplace injuries such as minor cuts, abrasions, and sprains. Class B kits cover more complex or high-risk sites and add the splint and tourniquet.
The aspirin line needs context. MedlinePlus, the National Library of Medicine’s consumer site, says to call 911 first during a suspected heart attack and to chew aspirin only when a physician or the 911 operator tells you to. That is why it sits in the case, not for headaches.
Home, Car, Trail, or Job Site: Sizing the Kit to the Setting
The Red Cross advises keeping a kit in your home and in your car, carrying one or knowing where to find one, and learning where the kits are at work. Each spot calls for a different build.
- Home. A well-stocked household case covers the cuts, burns, and sprains families deal with most. Toddler parents, anyone who cooks around hot oil, and a caregiver outfitting a parent’s house should plan past the bare minimum, often in the same trip that brings home bathroom grab bars.
- Car. A glove-box or trunk pouch handles a scrape or road rash. Pick a small first aid pouch that is easy to carry, and a mini version fits in luggage for travel.
- Trail. A backcountry bag adds wound closure strips, blister care, and, for trained users, a tourniquet and hemostatic dressings for injuries hours from a hospital. Outdoor activities punish loose packaging, so look for waterproof inner bags.
- Job site. OSHA regulation 1910.151 says that when no infirmary, clinic, or hospital is in near proximity, someone must be trained to render first aid and adequate supplies must be readily available. The rule itself does not list items, which is why employers lean on the ANSI classes above.
An IFAK (individual first aid kit) is a military-style bleeding-control pouch. It supplements a household case and only helps someone trained on it.
How to Judge a Kit on the Shelf
Judge a set on what is actually inside, how the case holds up, and how fast you can find one item with shaking hands. Piece count is the least useful number on the box, because a high count usually means the box is padded with small band-aids.
- Name the setting: home, car, jobsite, or trail. Each one changes what you need.
- Read the contents list in small type on the back, not the piece count on the front, and compare it with the family list above.
- Check the case: a hard-shell or waterproof case with labeled dividers gives quick access and protects dressings from moisture and crushing, which matters more in a truck bed than in a linen closet.
- Add what kits leave out: your own prescriptions, any prescribed epinephrine auto-injector, an oral dosing syringe for children’s liquid medicine, and emergency phone numbers.
Many kits carry ibuprofen and acetaminophen as single-dose packets, which travel better than loose pills in a pill organizer. Ask your pediatrician or another health-care provider about a child’s dose before you need it.
Then the red flags. A gas station checkout pouch holds a dozen bandages and nothing else, so it will not manage a deep cut or a burn. Sterile dressings, antiseptics, and pills all expire, and the date sits on each item rather than the case; the family list above also says to check dates regularly and replace used or out-of-date contents. Tape a card with your doctor, your pediatrician, and Poison Control (1-800-222-1222) inside the lid. Paper works when a phone is dead, the same reason spare batteries belong in that closet.
Supplies without skills are objects in a bag. A basic first-aid and CPR class is the cheapest upgrade on this page, and the charity behind that family list offers online classes as well as in-person training. Read the first aid manual that comes in the case, and call emergency services for anything past a minor injury.
Where to Buy a First Aid Kit in Store
Going in person lets you open a case and compare sizes. When we checked retailer sites on October 14, 2026, Target and Walgreens listed kits online, REI listed AMK products, and Walmart and CVS blocked our automated check, so confirm local stock in their apps.
Target
Target’s search showed its up&up store brand (an 85-piece kit and a 12-piece travel kit), Band-Aid Brand, Johnson & Johnson, Welly, and First Aid Only, including a vehicle kit and an ANSI Class A refill. Fine for home or car, thin on anything built for the backcountry.
Walmart, CVS, and Walgreens
Walmart and the two pharmacy chains carry compact options near the bandage shelf, and Walgreens runs a first aid kits category online. Selection leans toward small sets, but a local drug store is the fastest place to restock gauze, tape, iodine swabs, and antiseptic wipes.
REI
Browse their outdoor selection for hiking and backcountry kits, including AMK models such as the Ultralight/Watertight .3 and the Mountain Series Hiker. The same aisle carries the hydration packs competing for room in the same daypack.
Call ahead. Shelf tags and actual stock rarely match, and pharmacy locations carry the fewest sizes.
Buying Online: Amazon, Charity, and Maker-Direct Stores
Online is where specialty brands, workplace refill systems, and trauma-grade gear live. Amazon has the deepest catalog; maker sites list every size in a series.
| Seller | Best for | What to check |
|---|---|---|
| Amazon | Widest selection, fast delivery | Who ships it, return rules |
| Red Cross Store | The charity’s own family kits | Store availability |
| AMK | Hiking, camping, group trips | Which Ultralight/Watertight size |
| MyMedic | Bleeding-control kits | Training to use the gear |
| First Aid Only | Workplace cabinets and refills | ANSI class |
Amazon
Shop their full selection and study the contents photo rather than the bullet list. Check who ships it, too: marketplace sellers set their own return rules, unlike the stores with the best return policies. Some listings carry a California Proposition 65 warning, a state disclosure that the product can expose you to a chemical on California’s list, often in the plastic or vinyl case.
Red Cross Store
Visit the official store for the charity’s own kits; its contents page points shoppers to the Family First Aid Kit. The store returned a maintenance page during our October 14 check, so try again later if it does not load.
Maker-direct brands
Adventure Medical Kits (AMK) sorts its range into series (Mountain, Ultralight/Watertight, Sportsman, Trauma, Travel, Marine), and the Ultralight/Watertight line runs .3, .5, .7, .9, and Pro. MyMedic sells the MyFAK in Mini, standard, Large, and waterproof Pro versions, and says most of its kits include tourniquets and chest seals. First Aid Only sells SmartCompliance wall cabinets with a refill program. For anything sterile or medicated, buy from the manufacturer or an authorized retailer; unverified third-party listings are where expired dressings surface.
Paying With an FSA or HSA, and What Medicare Skips
The supplies inside generally qualify for tax-advantaged accounts; health insurance and Medicare generally do not pay.
FSA and HSA. IRS Publication 502 names bandages as a qualifying medical supply. Over-the-counter medicine is a separate rule: the CARES Act made OTC products and medications reimbursable without a prescription from HSAs and health FSAs for amounts paid after December 31, 2019. Keep the itemized receipt, and confirm a whole kit with your plan administrator.
Medicare. Part B covers durable medical equipment, which Medicare defines as built for repeated use, used in the home, and expected to last at least three years. A box of disposable supplies does not meet that definition.
Workplace. When OSHA’s rule applies, the supplies are the employer’s responsibility. Ask your safety officer before buying your own for the shop floor.
Five Kits Worth a Look
Prices move weekly, so we left most out. Each pick covers a different setting.
Large household or vehicle bag: Surviveware Large First Aid Kit. A bigger soft bag with room to add your own medication. Compare its contents photo against the family list above before you order. Check price on Amazon
Budget glove box: Band-Aid Brand All Purpose Compact First Aid Kit. Johnson & Johnson’s compact case with cleansing wipes, gauze pads, and brand-name bandages, cheap enough to buy one per car. Check price on Amazon
Hiking: Adventure Medical Kits Ultralight/Watertight .7. The middle of a five-size series with two-stage waterproofing; the maker steers solo day hikers to the smaller .3 and family campers to the .9. Check price on Amazon
Bleeding control: MyMedic MyFAK. Sized for three to five people, with the life-saving trauma gear consumer sets leave out. MyMedic.com listed it at 169.95 USD on October 14, 2026, and it is worth it only alongside training. Check price on Amazon
Workplace: First Aid Only SmartCompliance cabinet. A wall-mounted cabinet with a refill system; confirm the listing names the ANSI class your site needs. Check price on Amazon
Start where you spend the most unsupervised time, usually the car or the kitchen, and buy the first aid kit for that spot this week. Open it the day it arrives, check it against the checklist above, add your own medication, and write next October on the lid. Then do the second location.
First Aid Kit Questions, Answered
What are 10 things every first aid kit should have?
Adhesive bandages in assorted sizes, sterile gauze pads, adhesive tape, antiseptic wipes, antibiotic ointment, hydrocortisone ointment, tweezers, an oral thermometer, nonlatex gloves, and an emergency blanket. All ten appear on the Red Cross family-of-four list, which also adds a breathing barrier, a cold compress, roller and triangular bandages, aspirin, and printed instructions.
How do you get a first aid kit for free?
Employers, health plans, and community groups sometimes hand out basic sets at safety fairs, new-hire orientations, and emergency preparedness events. Ask your workplace safety officer first, since regulated worksites buy them in bulk. Treat a free one as a starter case, then add dressings and medication.
Do first aid supplies really expire?
Yes. Medication, ointments, and sterile dressings carry dates on each item rather than the case, so check them regularly and replace anything used or out of date. Medicine labels also list storage temperatures that a parked car in summer can exceed.
What is the difference between a Class A and Class B kit?
ANSI/ISEA Z308.1-2021 defines two workplace classes. Class A is for the most common workplace injuries, such as minor cuts, abrasions, and sprains. Class B is for more complex or high-risk sites, carries larger quantities (50 adhesive bandages instead of 16, for example), and adds a splint and a tourniquet.
Is a pre-made set better than building your own?
Pre-assembled sets take one click and arrive organized, which is why most buyers should start there. Building your own makes sense for narrow needs, such as blister care and closure strips for hiking or a survival kit with a water filter.
