First Aid Only 90583 25-Person First Aid Kit Refill Review (2026)

Is the First Aid Only 90583 the right refill for your First Aid Only 25-person kit?

Short answer: Yes — if the kit on your wall is a First Aid Only 25-person unit, the First Aid Only 90583 is the factory-matched restock: it restores the kit to its original ANSI fill, item for item, with zero guesswork about what maps where. For 25-person kits from other brands, the Urgent First Aid ANSI Class A Refill Kit does the same compliance job at effectively the same price.

The strongest argument for buying a kit from a major brand is the day it runs low: the manufacturer sells the exact refill. The First Aid Only 90583 25-Person First Aid Kit Refill is that product — the factory pack that returns a First Aid Only 25-person kit to its original ANSI fill in one order. First Aid Only is the most widely deployed workplace kit brand in the country, which makes this one of the most useful single SKUs in the First Aid Kit Refills collection. This review covers what the factory match is genuinely worth, which kits in the First Aid Kits collection it serves, and when a third-party pack is the equal buy.

Editorial verdict: 4.7/5. At $24.99, the First Aid Only 90583 is the no-thought restock for the most common workplace kit brand in America — the factory fill, matched to the box, at the same price as the generic alternatives. If you own a First Aid Only 25-person kit, this is the refill; there is nothing to overthink.

Who the First Aid Only 90583 is for

• Owners of First Aid Only 25-person kits — the First Aid Only 9302-25M Contractor Kit is the textbook match on our shelves.
• Safety coordinators standardized on First Aid Only across kits and cabinets from the Workplace First Aid Kits collection who want one refill SKU on the reorder sheet.
• Procurement desks that need a real manufacturer SKU (90583) on the PO rather than a marketplace listing name.
• Anyone whose 25-person box is sound but stale — the container outlives the fill every time.

What the First Aid Only 90583 does well

The factory match removes all guesswork

Generic refills work by mapping to the ANSI Z308.1-2021 class list; the 90583 works by simply being the fill the kit shipped with. Every component drops back into the pockets and compartments it came from — no auditing the pack against the label, no leftovers, no gaps. For the mechanics of what a compliant fill requires, our OSHA first aid kit requirements explained reference decodes OSHA 29 CFR 1910.151 and the ANSI class system it points to.

A real SKU on the paperwork

Most budget refills on the market carry no manufacturer part number, which turns reordering into archaeology. The 90583 is a published First Aid Only SKU — it goes on a purchase order, survives vendor changes, and shows up identically next year. In multi-site programs, that is worth more than any single component in the box.

The brand match is free

At $24.99, the 90583 sits within pennies of the Urgent First Aid Class A refill ($24.95). When the factory-matched pack costs the same as the generic, the decision for First Aid Only kit owners makes itself.

It anchors a one-brand restock program

Sites running the First Aid Only SmartCompliance 50-Person Kit, the First Aid Only 746000 SmartCompliance Cabinet, or the First Aid Only 90575 3-Shelf Cabinet can keep the whole estate inside one brand's refill line — same vendor, same quality baseline, one supplier relationship.

Where the First Aid Only 90583 falls short

25-person sizing is a hard ceiling

A 50-person kit or a 3-shelf cabinet will swallow this pack and still read half-empty. For the bigger formats, budget two packs — or move up to a large-format reload like the UniShield ANSI Class B Refill with Medications, which is built for 3- and 4-shelf cabinets.

The advantage is brand-specific

Drop the 90583 into a ProHeal or Ever Ready box and it becomes just another ANSI-fill refill — a perfectly good one, but no better than the Urgent First Aid pack at the same price. The premium logic only applies when the container matches the brand.

No medications, no trauma

Like most ANSI-fill refills, the 90583 carries no OTC medications and nothing for serious bleeding. Medication-inclusive cabinets restock with the UniShield Class B refill; bleeding-control stations restock from the Trauma Kits and Bleeding Control collection.

First Aid Only 90583 vs the competitive set

Against the field: the Urgent First Aid Class A refill is the brand-agnostic equal for non-First-Aid-Only boxes, the MFASCO pack charges a premium for injury-type organization, and the General Medi bag is a budget consumables top-up, not a compliance restock.

First Aid Only 90583 across the First Aid Only lineup

• Buy one 90583 if your station is a First Aid Only 25-person kit like the 9302-25M.
• Buy two if you run a 50-person First Aid Only unit and want to stay on the factory fill.
• Skip it for the big cabinets — a multi-shelf 90575-class cabinet restocks more sensibly from a large-format pack like the UniShield Class B refill.

Category context: factory refills inside a compliance program

OSHA 29 CFR 1910.151 requires first aid supplies to be "readily available," with ANSI Z308.1-2021 as the referenced fill benchmark — Class A for common workplace injuries, Class B for larger or higher-risk sites. Factory refills like the 90583 are the lowest-friction way to hold that line on a branded kit, because the restock decision is pre-made by the manufacturer. The upstream choices — class, format, station count — live in our complete first aid kit buyer's guide; between refills, component top-ups come from the Bandages and Wound Care collection and burn dressings from the Burn Care collection.

Total cost of ownership

A First Aid Only 25-person kit is a $20-$30 container with a consumable fill. One $24.99 refill per year keeps a typical office or contractor crew station fully stocked — roughly $1 per covered person per year — versus replacing the whole kit annually for marginally more, and throwing away a perfectly good box each time. Cabinets stretch the same logic further: the First Aid Only 746000 cabinet is a $123 one-time buy that then lives on refill economics indefinitely. See the best first aid cabinets guide for how the formats compare on lifetime cost.

Final verdict: 4.7/5

The First Aid Only 90583 earns the highest rating on our refill shelf for a simple reason: it makes the correct restock decision automatic for the most widely owned workplace kits in the country, at a price that charges nothing for the privilege. Buy this if your 25-person kit says First Aid Only on the lid. Buy the Urgent First Aid Class A refill for any other brand of 25-person Class A box, or the UniShield Class B refill with medications when a big cabinet needs a full medication-inclusive reload.

First Aid Only 90583 Refill — FAQ

Which kits does the First Aid Only 90583 refill fit?

It is the factory restock for First Aid Only 25-person kits — the First Aid Only 9302-25M contractor kit is the direct match in our catalog. It also works as a standard ANSI-fill refill in other brands' 25-person boxes, where it competes on even terms with generic packs.

Is the First Aid Only 90583 ANSI compliant?

The pack restores a First Aid Only 25-person kit to its original ANSI fill as shipped. Check your kit's label for its rated class and person count before ordering — the label, not the refill, defines what the station must contain. Our OSHA first aid kit requirements reference explains the class system.

First Aid Only 90583 vs Urgent First Aid Class A Refill — which should I buy?

On a First Aid Only kit, the 90583 — the factory match at the same price. On any other brand, the two are functionally interchangeable; see the Urgent First Aid Class A refill review for that pack's own case.

First Aid Only 90583 vs MFASCO Class A Refill — which is better?

The MFASCO pack costs $19 more and arrives organized by injury type, which speeds up loading multi-shelf cabinets. The 90583 is the value pick for single-box kits and the automatic pick for First Aid Only containers.

Will one 90583 pack refill a 50-person First Aid Only kit?

No — it is sized for 25-person units. For a First Aid Only 91248 50-person kit or SmartCompliance 50-person unit, order two packs to stay on the factory fill.

Does the First Aid Only 90583 include medications?

No OTC medications ship in this pack. Programs that stock medications restock that layer separately — the UniShield Class B refill with medications is the medication-inclusive pack on our shelf.

Can I use the 90583 in a wall cabinet?

In a small 25-person-scale cabinet, yes. Multi-shelf cabinets like the First Aid Only 90575 need multiple packs or a large-format reload — compare options in the cabinets collection.

How often should I reorder the 90583?

Inspect the kit monthly or quarterly; reorder when stock drops below the label's fill or when dated items approach expiration. Most 25-person stations settle into one refill per year plus occasional single-item top-ups.

Do the 90583 contents expire?

Dated items — antiseptics and ointments — carry expiration dates; dressings and bandages last longer but must stay sealed. A stale fill can fail an inspection even when the box looks full, which is exactly what a scheduled refill prevents.

Does refilling with the 90583 keep my kit OSHA-compliant?

OSHA 29 CFR 1910.151 requires adequate, readily available supplies and points to ANSI Z308.1 as the fill benchmark. Restoring a rated kit to its original fill with the factory refill is the cleanest way to stay on the right side of that requirement — details in our requirements reference.

Is the 90583 right for a construction crew kit?

For a 25-person contractor kit like the 9302-25M, yes — that is its home turf under OSHA 1926.50 site expectations. Larger or higher-risk crews should be on Class B stations; the best workplace first aid kits guide ranks the site-rated options.

What does the 90583 NOT restock?

Anything trauma-level: no tourniquets, hemostatic gauze, or pressure dressings. Jobsite bleeding-control stations restock from the Trauma Kits and Bleeding Control collection — see the North American Rescue wound packing gauze for that layer.

Should I refill my First Aid Only kit or just buy a new one?

Refill. The plastic case, gasket, and wall mount are the durable half of the product; the fill is the consumable half. Replace the container only when it is physically damaged — otherwise the refill delivers the same compliance for half the money.

Can I mix the 90583 with single-item restocks?

Yes — the standard pattern is an annual 90583 plus as-needed singles: Band-Aid Flexible Fabric bandages, Curad blue detectable knuckle bandages for food areas, or First Aid Only Water Jel burn dressings to stay in-brand on the burn layer.

Where does the 90583 fit if I am building a program from scratch?

Pick the container first via the which first aid kit do you need guide; if you land on First Aid Only hardware from the workplace kits collection, put the 90583 on the reorder schedule the same day.
