6-pack vs 12-pack: 20x25x1 cost
For the common 20x25x1 furnace/AC size, a bigger multi-pack usually cuts the per-filter price — but brands do not sell matching 6 and 12 counts. Filtrete often sells a 6-pack; Honeywell Store sells 4-packs and 12-packs. Use $/filter (pack price ÷ count), then buy the printed size that matches your slot.
Quick answer
- Honeywell Store 12-pack beats three 4-packs on the same MERV line (re-checked 6 Sep 2026): MERV 8 saves about $6.90 per year of filters; MERV 11 about $12.90; MERV 13 about $11.90.
- Filtrete Target 6-pack (MPR 1000 / MERV 11) landed at $55.99 ($9.33/filter) on the last Target fill — compare that $/filter to Honeywell’s MERV 11 12-pack at $8.66/filter before you mix brands.
- Storage and change cadence matter: a 12-pack is roughly a year of quarterly 1-inch changes. See how often to change.

Filtrete 6-pack (Target) vs Honeywell 12-pack
This is a cross-brand $/filter check, not the same media. Filtrete MPR 1000 is commonly labeled MERV 11. Prefer Target Filtrete over Walmart when both exist.
| Listing | Pack | Price that day | Per filter | Merchant |
|---|---|---|---|---|
| Filtrete 20x25x1 MPR 1000 Allergen Defense | 6 | $55.99 | $9.33 | Target |
| Honeywell 20x25x1 High Efficiency (MERV 11) | 12 | $103.95 | $8.66 | Honeywell Store |
| Nordic Pure 20x25x1 MERV 8 (reseller) | 24 | $170.99 | $7.12 | JB Tools |
| Nordic Pure 20x25x1 MERV 13 (reseller) | 24 | $233.99 | $9.75 | JB Tools |
On this snapshot, Honeywell’s MERV 11 12-pack is cheaper per filter than the Filtrete Target 6-pack. Nordic Pure’s large 24-packs (via JB Tools) undercut Honeywell MERV 8 on $/filter but use a slightly smaller cut (~19.5 × 24.5).

When a smaller pack still wins
- You are changing size or MERV soon — do not stock a year of the wrong cut.
- Damp storage — cardboard multi-packs hate basements; buy what you will use in a few months.
- Subscribe-and-save / store-only deals — a sale 4-pack or 6-pack can briefly beat the list 12-pack; re-check the cart before checkout.
- Odd schedule — pets, smoke, or renovation may need monthly changes; a 12-pack still works, but cash outlay is larger up front.
