Midea Refrigerator Water Filter: MIWF6200 vs MIWF8200 vs MIWF8900

Midea currently sells three refrigerator water filters – MIWF6200, MIWF8200, and MIWF8900 – and mixing them up is easy, because Midea builds refrigerators sold under its own name and under retailer labels like Insignia and IKEA’s OVERSKADLIG. Buy the wrong one and it either won’t seat right or won’t certify the reduction you think you’re getting. This guide starts with the fastest way to confirm which Midea refrigerator water filter your fridge actually takes, then walks through what each one is certified to remove, what it costs, and when an aftermarket option is a safe substitute.

All three current filters are listed by NSF at 200 gallons and 0.5 gpm under NSF/ANSI 42, for chlorine, taste and odor, and Class I particulate reduction (NSF’s Midea listing). Past that baseline, they split: MIWF6200 and MIWF8200 add NSF/ANSI 53 for cyst and lead reduction only, while MIWF8900 carries a much longer NSF/ANSI 53 and NSF/ANSI 401 list (NSF 53 Midea listing, NSF 401 Midea listing).

Match Your Midea Refrigerator Water Filter by Model Number

The fastest identification method is your refrigerator’s full model number, printed on a plate usually just inside the fridge compartment.

• MRF29D3AST, MRF29D2AST, MRF29D6AST, MRF29D9BST (29 cu. ft. French-door line) take MIWF8200. Encompass, Midea’s parts distributor, lists part 12131000093558 as “Water Filter MIWF8200” for all four models, and AJ Madison confirms MIWF8200 for three of them (Encompass MIWF8200, AJ Madison MIWF8200).
• MRF27I6BST and MRF32I6BST (the Counter-Depth and Standard-Depth PLUS lines) take MIWF8900. Midea’s own shared owner’s manual covers both models, and their Encompass parts pages both list filter assembly 12131000106258 – which Parts Town identifies directly as “WATER FILTER MIWF8900” (Midea MRF27/MRF32 manual, MRF27I6BST parts, Parts Town MIWF8900). Lowe’s Q&A for the MRF27I6BST independently confirms MIWF8900 ships in that fridge (Lowe’s MRF27I6BST Q&A).
• MRS26D5AST, MRS26D7AST, MRQ22D7AST, MRQ22D4AST, plus older or retailer-relabeled models like SBS263W, SBS263SS, FD216SS, CSBR260M4S, and IKEA’s OVERSKADLIG, all take MIWF6200. Encompass identifies part 12131000074406 as “Water Filter MIWF6200” across those models (Encompass MIWF6200).

One model needs a caution flag. MRF29D6AST is a drift risk: Midea/Encompass splits it into a “NO REVISION” build and a “REV A” build, and both parts pages surface both 12131000093558 (MIWF8200) and 12131000074406 (MIWF6200) in the predicted-parts area (MRF29D6AST no-revision parts, MRF29D6AST Rev A parts). The public item page for 12131000093558 names MRF29D6AST directly, so MIWF8200 is the default recommendation – but confirm it against your installed filter before ordering.

Read the Filter You Already Have

If your model number isn’t a clean match above, the printed part number on your current cartridge settles it faster than any model lookup. Pull the old filter and check the number stamped on the body against 12131000074406 (MIWF6200), 12131000093558 (MIWF8200), or 12131000106258 (MIWF8900). That single check works even when a fridge has been relabeled for a retailer or when a household doesn’t know the exact production revision.

Run your model or filter part number through our filter finder to confirm the match and see the certification status stated plainly next to it – the same 60-second habit that prevents the wrong-filter purchase across every fridge brand, as we cover in Are Water Filters Interchangeable?

What Each Midea Refrigerator Water Filter Is Actually Certified to Remove

The NSF listings, not the retail packaging, are the source of truth here.

MIWF6200 is NSF-listed as MF-2008-R2 (aliases NS-WF26SS0-1 and MIWFT2100). Its NSF/ANSI 53 line covers cyst and lead reduction only – nothing more, per the official NSF 53 Midea listing. No NSF/ANSI 401 listing was found for it.

MIWF8200 is NSF-listed as MF-2812-R4, and it carries the same cyst-and-lead-only NSF/ANSI 53 claim (NSF lead-reduction listing). NSF marks it [Pb], meaning it was separately evaluated for lead-content compliance under the plumbing laws tied to the Safe Drinking Water Act – a materials check, not an extra reduction claim.

MIWF8900 is the strongest Midea-listed filter in the current NSF data. Listed as MF-1807-R5B, its NSF/ANSI 53 line adds asbestos, atrazine, benzene, carbofuran, lindane, mercury, p-dichlorobenzene, and toxaphene reduction on top of cyst and lead. Its NSF/ANSI 401 listing covers 14 named emerging compounds – including microplastics, bisphenol A, DEET, ibuprofen, and naproxen – reduction (NSF 401 Midea listing). If you’re weighing whether that broader claim list actually matters for your water, the standards themselves are explained in our NSF filter certifications guide.

None of the three current Midea filters carry a PFOA/PFOS reduction claim in the NSF data reviewed – worth knowing if that’s your specific concern; see our refrigerator filter PFAS check for how that compares across brands.

A Retailer Claim Worth Double-Checking

Lowe’s product page for MIWF8200 describes it as “NSF 53 and 42” certified to reduce chlorine, asbestos, cysts, lead, mercury, and other contaminants (Lowe’s Midea filter listing). NSF’s own official Midea 53 listing for that same filter shows cyst and lead reduction only – no asbestos, no mercury claim on the accredited listing. That gap is exactly why NSF’s consumer guidance tells shoppers to check the database-listed claim rather than trust a retailer’s contaminant list at face value (NSF contaminant claims guide). Before you buy a Midea refrigerator water filter for a specific contaminant, read the NSF listing yourself.

Replacement Cost and Cadence

Prices vary by seller and change over time; these were what we observed on August 6, 2026.

Sources: cadence figures come from the MRQ22D7AST manual and the shared MRF27I6BST/MRF32I6BST manual (Manualzz MRQ22D7AST manual, Midea MRF27/MRF32 manual); prices from Encompass, AJ Madison, and MideaParts. MIWF8900 also turned up out of stock or at a $92.76-$99.00 premium at two smaller sellers during our check – shop around before assuming the OEM channel is always cheapest.

Aftermarket and Cross-Compatible Options

Some Midea refrigerator water filter part numbers are shared aliases, not competing aftermarket copies. NSF lists NS-WF26SS0-1 and MIWFT2100 under the same MF-2008-R2 element as MIWF6200 – when the listed product matches exactly, it inherits the same NSF 42 and 53 claims (NSF Midea listing). Similarly, WF200 appears alongside MIWF8900 under MF-2008-TG for NSF/ANSI 42 only – don’t assume that row extends to the broader MIWF8900 NSF 53/401 claims unless the exact element matches. The same trap appears one row up: MIWF8900, MIWF8700, and WF200V1 do share the MF-1807-R5A listing, but only under NSF/ANSI 42. Under NSF/ANSI 53 and 401, the MF-1807-R5A rows list MIWF8700 and WF200V1 only – MIWF8900’s broader 53/401 claims sit under MF-1807-R5B instead (NSF Midea listing). Sharing a listing code for one standard does not mean sharing it for all three, and the exact refrigerator fit still needs confirming by installed filter or head.

True aftermarket is a different story. Generic marketplace listings – one example is a part sold as MM021 – claim compatibility with MIWF6200, MF-2008-R2, and even other brands’ filters (Sharp SJWF200, Thor WF200, ZLINE MIWFT2100, Insignia NS-WF26SS0-1), and the listing copy invokes “NSF/ANSI 42” language (Snapklik MM021 listing). Marketplace copy claiming a standard is not the same as an official listing – treat it as unverified until you find that exact brand and model in NSF, IAPMO, or WQA’s own databases. Waterdrop is a useful example of the same caution in reverse: the brand holds many NSF listings for other refrigerator filters, but no MIWF6200 match turned up in the official NSF results we reviewed, so don’t assume Waterdrop has a certified MIWF6200 replacement without checking the exact listing yourself (Waterdrop NSF page).

When You Can’t Confirm Your Model

If your filter has no legible part number and your refrigerator’s model plate is worn or missing, don’t guess. Check the owner’s manual for your exact model – Midea publishes them by model number, as with the shared MRF27I6BST/MRF32I6BST manual – or contact the retailer you bought the fridge from if it carries a store label rather than the Midea name. Guessing between MIWF6200, MIWF8200, and MIWF8900 risks a filter that won’t seat correctly or one that seats fine but carries a narrower certification than you assumed.

What to Do Next

Once you’ve confirmed which Midea refrigerator water filter your model takes, verify the exact SKU’s current NSF listing before you buy – especially if a specific contaminant like lead is your reason for filtering at all. Our filter certification registry keeps this lookup done in advance, brand by brand and SKU by SKU, and our filter finder ties your model straight to the OEM part and any verified aftermarket alternatives.
