First Aid Only 106 Piece Refill Pack (223-REFILL) Review (2026)

Is the First Aid Only 106 Piece Refill Pack (223-REFILL) the right restock for a 223-U kit?

Short answer: Yes — if you own a First Aid Only 223-U 25-person kit, this is the refill built to match it. The model number is the tell: First Aid Only 106 Piece Refill Pack (223-REFILL) carries the same "223" prefix as the First Aid Only 223-U OSHA-Compliant First Aid Kit, 25-Person it's paired with, following First Aid Only's own numbering convention. If you don't own a 223-U and just need any brand-agnostic 25-person Class A restock, the Urgent First Aid ANSI Class A Refill is the more general-purpose pick.

Refill packs live and die on one question: does this actually match my kit? First Aid Only answers that question in the product name itself. The First Aid Only 106 Piece Refill Pack (223-REFILL) is a 106-piece pack whose "223-REFILL" designation mirrors the "223-U" designation on First Aid Only's own 25-person OSHA-compliant kit — a naming pattern that's about as close to an official factory match as a refill line gets without a manufacturer statement spelling it out. This review looks at where it sits in the First Aid Kit Refills collection, how it stacks up against the other First Aid Only refill on our shelves, and which kits and cabinets across the First Aid Kits collection it's actually built to restock.

Editorial verdict: 4.5/5. At $23.97, the First Aid Only 106 Piece Refill Pack (223-REFILL) is the closest thing to a factory-matched restock for a 223-U kit that the market offers — the model-number pairing is a real signal, not marketing copy, and the price undercuts the alternative First Aid Only refill by a dollar.

Who the First Aid Only 106 Piece Refill Pack is for

• Anyone who owns a First Aid Only 223-U OSHA-Compliant First Aid Kit and wants the closest thing to a factory-matched restock rather than a guess.
• Facilities teams standardized on First Aid Only who'd rather keep every kit and cabinet in the building on one vendor's refill line.
• Safety coordinators restocking 25-person kits from the Workplace First Aid Kits collection on a routine schedule.
• Anyone with a sound but empty 223-U kit — if the case and latches are fine, refilling it costs a fraction of buying a new one.

What the First Aid Only 106 Piece Refill Pack does well

The naming convention is a real factory-match signal

First Aid Only's "223-U" kit and "223-REFILL" pack share a model prefix, and that's not a coincidence a retailer manufactures on its own — it's how First Aid Only organizes its own product line. That naming logic is the strongest evidence on the market that this pack was designed specifically to restock the 223-U kit, the same way the First Aid Only 90583 is the general 25-person refill in the same brand family. It's a reasonable inference from the product names, not a manufacturer confirmation — but it's the clearest pairing signal in this entire refill category.

More pieces than the leading brand-agnostic alternative, at a lower price

At 106 pieces for $23.97, this pack beats the 78-piece Urgent First Aid Class A Refill on both piece count and price. For a buyer who already owns First Aid Only equipment and isn't shopping on brand-agnostic terms, that combination is hard to beat.

The economics beat replacement

A new First Aid Only SmartCompliance 50-Person OSHA First Aid Kit runs $99.73; the case doesn't wear out, only the fill does. At $23.97, this refill is the cheapest way to keep a sound 223-U case in service rather than replacing the whole unit.

A clean anchor for a First Aid Only-standardized restock routine

Because it's a single line item tied to a specific kit by name, it's an easy reorder point to build a schedule around: inspect on a quarterly cycle, reorder the matching pack the moment the kit drops below a usable fill or dated items start to age out.

Where the First Aid Only 106 Piece Refill Pack falls short

No stated compliance claim on the refill itself

The product title doesn't state an ANSI class or claim OSHA compliance for the refill pack — only the 223-U kit's own listing does. Treat this pack as stocked for OSHA/ANSI first aid programs rather than independently certified, and verify your kit's rating against our OSHA first aid kit requirements reference before ordering.

25-person sizing is a hard ceiling

A 50-person kit like the First Aid Only 91248 or a 100-person kit like the First Aid Only 91247 will absorb this pack without reaching a full fill — budget multiple packs or step up to the First Aid Only 700002 SmartCompliance 50-Person Refill instead.

Bulk organization, not injury-type organization

Like most 25-person refill packs, this one arrives as bulk components rather than sorted by injury type. The MFASCO ANSI Class A First Aid Kit Refill Pack organizes its fill by injury type, which is worth the extra cost if multiple people load your cabinets.

First Aid Only 106 Piece Refill vs the competitive set

Against the field: this pack wins on piece count and price against every other 25-person First Aid Only or brand-agnostic refill on our shelves, but the Urgent First Aid Class A Refill is the better call if your kit isn't First Aid Only at all, and the MFASCO pack wins on injury-type organization for a premium.

First Aid Only 106 Piece Refill vs First Aid Only 90583 — the in-brand decision

• Buy the 223-REFILL if you own the 223-U kit specifically — the model-number pairing and lower price both favor it.
• Buy the 90583 if you own a different First Aid Only 25-person kit that doesn't carry a "223" prefix, or simply want the brand's general-purpose 25-person refill.

Which kits and cabinets this refill restocks

The natural pairing is the First Aid Only 223-U OSHA-Compliant First Aid Kit, 25-Person — the kit the model number is named after. Beyond that specific pairing, it works reasonably well for other First Aid Only 25-person units like the First Aid Only 9302-25M Contractor Kit and can top up small third-party 25-person Class A kits such as the ProHeal 10-Person ANSI Class A First Aid Kit paired with a second unit, or small metal cabinets like the Medique 712MTM 3-Shelf First Aid Cabinet.

Category context: refills inside a first aid program

OSHA's 29 CFR 1910.151 requires adequate first aid supplies to be "readily available" — a requirement a picked-over kit fails regardless of what the box on the wall says. The 223-U kit's own listing states it is OSHA-compliant; keeping it filled with a matched refill is how that compliance status stays real rather than nominal. This refill's own listing doesn't restate an ANSI class or an OSHA claim, so treat it as stocked for OSHA/ANSI first aid programs rather than independently certified. Our OSHA first aid kit requirements explained reference covers 29 CFR 1910.151 and ANSI Z308.1 in full; upstream container decisions are covered in the which first aid kit do you need buyer's guide.

Total cost of ownership

A 223-U kit is a buy-once case with a consumable fill. The fill turns over on two clocks: usage (bandages and wound-care items go first) and expiration (dated items age out even in a closed case). For a typical 25-person site, one $23.97 refill per year plus occasional single-item top-ups from the Bandages and Wound Care collection keeps the kit usable for well under $1 per employee per year — against $99.73 to replace a comparable case outright with the First Aid Only SmartCompliance 50-Person Kit.

Final verdict: 4.5/5

The First Aid Only 106 Piece Refill Pack (223-REFILL) does one job — restocking a 223-U kit with the closest thing to a factory match on the market — and does it at a price that beats every other 25-person refill in the First Aid Only line. Buy this if you own the 223-U kit or another First Aid Only 25-person unit. Buy the First Aid Only 90583 for a different First Aid Only kit without a "223" model number, the Urgent First Aid Class A refill for any non-First Aid Only 25-person kit, or the MFASCO pack when injury-type organization matters more than brand matching.

First Aid Only 106 Piece Refill Pack (223-REFILL) — FAQ

Is the First Aid Only 106 Piece Refill Pack ANSI or OSHA compliant?

The refill's own listing doesn't state an ANSI class or claim OSHA compliance — that claim belongs to the 223-U kit it's designed to restock. Treat this pack as stocked for OSHA/ANSI first aid programs rather than independently certified. Our OSHA first aid kit requirements reference covers the underlying standard.

What kit is the 223-REFILL designed to restock?

The model number points directly at the First Aid Only 223-U OSHA-Compliant First Aid Kit, 25-Person. The shared "223" prefix follows First Aid Only's own naming convention, which makes this the natural factory-matched refill for that kit.

First Aid Only 106 Piece Refill vs First Aid Only 90583 — which should I buy?

If you own the 223-U kit, buy this pack — the model number is a named match and it's a dollar cheaper. If you own a different First Aid Only 25-person kit, the First Aid Only 90583 is the brand's general-purpose 25-person refill.

First Aid Only 106 Piece Refill vs Urgent First Aid Class A Refill — which is better?

This pack has more pieces (106 vs 78) and costs slightly less, plus the named match to the 223-U kit. The Urgent First Aid Class A Refill is the better pick if your kit isn't First Aid Only branded at all — see our Urgent First Aid Class A Refill review for the full breakdown.

Will this refill work in a kit or cabinet that isn't First Aid Only branded?

It can top up any 25-person-rated kit or small cabinet, but the model-number pairing that makes it the strongest pick applies specifically to the 223-U kit. For a non-First Aid Only 25-person kit, the brand-agnostic Urgent First Aid Class A Refill is an equally valid choice.

How many pieces come in the First Aid Only 223-REFILL?

106 pieces, sized to restock a 25-person kit or small cabinet in one order.

Does the 223-REFILL restock a 50-person kit?

No — it's sized for 25-person kits. For a 50-person unit like the First Aid Only 91248, order two packs or step up to the First Aid Only 700002 SmartCompliance 50-Person Refill.

How often should I restock a 25-person first aid kit?

Inspect quarterly, refill whenever stock runs thin, and do a full dated-item sweep at least annually. Most 25-person sites land on one full refill per year plus occasional single-item top-ups from the Bandages and Wound Care collection.

Do first aid refill contents expire?

Dated items — antiseptics, ointments, and any OTC medications — carry expiration dates and must be replaced when they lapse. Bandages and dressings keep longer but should stay sealed and clean. An expired fill can fail an inspection even inside a full case.

Does this refill include OTC medications?

The listing doesn't call out a medication component. If your program needs a medication-inclusive reload, the UniShield ANSI Class B First Aid Refill with Medications is the pack on our shelf built explicitly around that.

Is this refill right for a construction crew?

A single 25-person Class A-style refill may undersize a larger construction crew's exposure. For higher-risk or bigger sites, compare options in the best workplace first aid kits guide and consider a Class B-format pack such as the Urgent First Aid Class B Refill.

What should I check before ordering a refill instead of a new kit?

Confirm the case, latches, and mount are sound — replace the whole unit only when the container itself is damaged. Compare cabinet pricing in our best first aid cabinets guide before deciding.

Is there a trauma-level refill equivalent?

For IFAK and bleeding-control stations, refills are a different category — see the RHINO RESCUE IFAK Refill Kit with CAT Gen-7 Tourniquet. This 106-piece pack does not restock tourniquets or hemostatic dressings.

Where does this refill fit if I'm building a program from scratch?

Start with the container decision in the which first aid kit do you need guide, buy the 223-U kit or another 25-person unit from the workplace kits collection, then put this refill on the reorder schedule from day one.

First Aid Only 106 Piece Refill vs MFASCO Class A Refill — which is better?

The MFASCO pack costs almost double but arrives sorted by injury type, which speeds up loading multi-shelf cabinets. This pack is the value pick, and the only one of the two with a named match to a specific First Aid Only kit.
