Find a replacement filter by the full model number.

Levoit’s product page says this genuine replacement filter is compatible with Core 200S-P only. This OEM statement does not validate aftermarket equivalents or compare filtration performance.

Levoit lists Core 300-P, Core P350-P, and Core 300-P-RAC for this original filter. The page does not include Core 300S-P in this specific filter listing; do not infer across the shared 300 name.

Levoit explicitly includes Core 300S-P for this smoke-remover variant. That does not establish fit for every Core 300-P filter version; check each filter variant’s own model list.

Levoit explicitly lists Core P350-P for the Core 300-P original replacement filter. This record is for that named original filter only, not every Core 300-series variant.

Levoit explicitly lists the RAC-suffix model for the Core 300-P original replacement filter. Keep the suffix when checking; this entry does not broaden fit to other 300 models.

Levoit states this genuine replacement filter is compatible with Core 400S-P only. No cross-model or aftermarket equivalence is established.

Levoit identifies the original replacement filter for Core 600S-P and lists LRF-C601-WUS as the filter model. Levoit also has other filter variants for the purifier; this note covers the original only.

Levoit says the LV-H133-RF replacement is compatible with LV-H133 only. Similar model numbers are not treated as aliases.

Levoit says the LV-H134-RF replacement is compatible with LV-H134 only. This is a separate record from LV-H133 despite the similar model number.

WINIX’s official Filter A page lists C535 among its compatible models and identifies the filter as SKU 115115. The brand’s listed compatibility does not establish equivalence for other manufacturers’ products.

WINIX's current Filter A, Filter G, and Filter Pack P pages each name model 5500. Filter A is described as a complete one-year set. Filter Pack P is compatible with model 5500 and with washable True HEPA 115122 sold separately. These are separately listed product paths, not a claim that components are interchangeable. The Filter G page title and image show 115122, while its description includes 115112; verify the code on the installed filter or ask WINIX support if unclear.

WINIX's Filter H page names the AM80 and the 5500-2 as compatible. The AM80 manual independently identifies Filter H / SKU 116130. The part is shared with another exact purifier model.

WINIX's Filter H page names the 5500-2 and AM80 as compatible, and the 5500-2 manual independently identifies Filter H / SKU 116130. The Filter A page names original 5500 without “-2” and does not name the 5500-2. This is US-source OEM evidence only.

WINIX names C545 as the compatible purifier for Filter S / SKU 1712-0096-00. Similar Winix model names do not establish a shared part.

Honeywell’s model page identifies HPA100 as using one R HEPA filter and one A odor-reducing pre-filter. Honeywell also cautions that compatible replacement filters are not guaranteed to offer the same performance or efficiency.

Honeywell names HPA100 and HPA104 on its medium-room product page and specifies one R HEPA filter and one A pre-filter for the configuration. Retain the 104 suffix when matching the label.

Honeywell’s filter guide groups HPA200/HPA204 as Large and specifies two R HEPA filters plus one A or A+ pre-filter for that size. This is family-level guidance, not a serial-number revision check.

Honeywell explicitly groups HPA200/HPA204 and specifies two R HEPA filters plus one A or A+ pre-filter for this Large configuration. Keep the 204 suffix; the source does not check serial-number revisions.

Honeywell’s filter guide groups HPA300/HPA304 as Extra Large and specifies three R HEPA filters plus one A or A+ pre-filter. Confirm the full model and package quantity from Honeywell documentation.

Honeywell explicitly groups HPA300/HPA304 and specifies three R HEPA filters plus one A or A+ pre-filter. This is a family-level grouping rather than a serial-number-level revision check.

Blueair states this filter is compatible with Blue Pure 211+ and explicitly says it is not compatible with 211+ Auto. “Auto” is a material model distinction.

The US Blueair product-page FAQ explicitly names the original Blue Pure 211 as compatible with this filter. Check the exact model label; the separate 211+ Auto and 211i Max records do not become aliases for the original 211.

Blueair says this replacement filter is compatible only with the Blue Pure 311 Auto air purifier. A similar 311 model name alone does not establish fit.

Levoit names the Core Mini-P and calls the replacement Core Mini-RF. It is not conflated with LV-H128.

Levoit lists a dedicated LV-H132-RF replacement. Similar LV-H13x model numbers remain separate entries.

Levoit maintains a distinct LV-H128 listing. The catalog entry is a lead to verify against the current product detail, not a claim that it fits the visually similar Core Mini-P.

Levoit presents a genuine Vital 100S-P family replacement and separate specialty carbon filter options. Their filter model codes differ by variant.

Blueair's filter page names only the Blue Pure 211i Max for this model-specific filter family, distinct from 211+, 211+ Auto, and 211i Max.

The Canadian page states this replacement is only compatible with the Blue Pure 311i Max. This evidence is market-labelled Canada.

Blueair's US catalog lists several 511i Max filter variants. This is a family-level catalog record; open the selected filter's own details before purchase.

WINIX's US Filter O page lists A230, A231, and T500. This source supports only the named OEM reference and does not establish local stock or aftermarket performance.

WINIX's US Filter O page lists A231, A230, and T500. The A230 and A231 suffixes are retained as separate exact model records because the manufacturer page names both.

WINIX's US Filter O page explicitly lists T500, A230, and A231. This does not imply the similarly named Filter T is compatible; use the exact OEM SKU shown here.

WINIX's US Filter R page names T810 and T830. It does not name T820, so the app leaves T820 unresolved instead of projecting the mapping across a product family.

WINIX's US Filter R page names T830 and T810. This mapping is from the explicit fit line, not from the T830/T810 family name or an adjacent manual listing.

WINIX's US Filter Z page explicitly lists C610 and C710. It does not establish fit for other C-series purifiers.

WINIX's US Filter Z page explicitly lists C710 and C610. The shared part is a two-model result if an owner searches the filter SKU.

Blueair's US page names 411i Max and 411i+ Max; the official Canada catalog also lists 411a Max in the 411 Max filter family.

Regional series wording varies. Confirm the complete purifier label and check the corresponding US or Canadian manufacturer listing; do not infer across older 411 / 411 Auto generations.

Coway explicitly names both Airmega 200M and Airmega AP-1512HH as compatible with this filter set.

This set contains separate pre/deodorization and HEPA pieces. Read the product description for the selected bundle and compare the full device label.

Coway publishes a separate replacement set for the AP-1512HHS model, distinguishing it from the AP-1512HH/200M listing.

Do not substitute the AP-1512HH/200M set based on the shared AP-1512 prefix. Confirm the full HHS suffix and parts in the package.

Coway explicitly lists Airmega 150 as compatible with its Airmega 150 & 160 Filter Set, SKU 3108979. The set includes a HEPA filter and two deodorization filters.

US-source compatibility statement only. It does not establish local stock, shipping, or warranty outside the source market, and it does not test aftermarket fit or performance.

Coway explicitly lists Airmega 160 as compatible with its Airmega 150 & 160 Filter Set, SKU 3108979. The set includes a HEPA filter and two deodorization filters.

US-source compatibility statement only. It does not establish local stock, shipping, or warranty outside the source market, and it does not test aftermarket fit or performance.

Coway names Airmega 250 for the Max2 Filter, SKU 3109144. Its official support article requires the five-character code after the first three serial characters to be 02F9S or 02F9R; this result stays unconfirmed until the user checks that code.

Enter only the five-character serial code in the checker. US-source OEM evidence only; no stock, delivery, or warranty claim is made for Canada or the UK. The product title also mentions 250ART, but detail and support text here do not confirm 250ART, so it is excluded.

Coway names Airmega 250S for the Max2 Filter, SKU 3109144. Its official support article requires the five-character code after the first three serial characters to be 02F9S or 02F9R; this result stays unconfirmed until the user checks that code.

Enter only the five-character serial code in the checker. US-source OEM evidence only; no stock, delivery, or warranty claim is made for Canada or the UK. The product title also mentions 250ART, but detail and support text here do not confirm 250ART, so it is excluded.

Coway names Airmega 300 and 300S as compatible with the Max2 Filter Set, SKU 3104757. The set contains two Max2 filters, one for each side of the purifier.

US-source compatibility statement only. It does not establish local stock, shipping, or warranty outside the source market, and it does not test aftermarket fit or performance.

Coway names Airmega 300S alongside Airmega 300 as compatible with the Max2 Filter Set, SKU 3104757. The set contains two Max2 filters, one for each side of the purifier.

US-source compatibility statement only. It does not establish local stock, shipping, or warranty outside the source market, and it does not test aftermarket fit or performance.

Coway names Airmega 400 and 400S for the Max2 Filter Set, SKU 3104756. The set contains two Max2 filters, one for each side of the purifier.

US-source compatibility statement only. It does not establish local stock, shipping, or warranty outside the source market, and it does not test aftermarket fit or performance.

Coway names Airmega 400S alongside Airmega 400 for the Max2 Filter Set, SKU 3104756. The set contains two Max2 filters, one for each side of the purifier.

US-source compatibility statement only. It does not establish local stock, shipping, or warranty outside the source market, and it does not test aftermarket fit or performance.

The C909 manual names Filter A / SKU 115115. WINIX separately lists C909 as compatible with the Filter A +AllergenGuard annual set, SKU 1712-0004-10. This is a distinct product/set identifier, not an alias for or proof of equivalence to SKU 115115.

US-source evidence only; no Canada or UK fitment or availability is established. Treat the annual set as a distinct OEM product from Filter A SKU 115115. Aftermarket fit and performance are untested.

Guardian Technologies identifies the selected purifier variant as AC4825E and lists HEPA Filter B FLT4825 as a compatible replacement. Its separate filter page also lists AC4825E. This row covers the original FLT4825 part only.

Do not infer that all Filter B variants are identical. US-source evidence only; it does not establish Canadian or UK stock, shipping, warranty, or local compatibility details, and does not rate aftermarket filters.

Philips UK names AC2887, AC2889, AC2892, and AC3829 as compatible with the FY2422/30 filter. Philips US also carries a matching model list.

Suffixes and full device-region SKUs may differ. This is a shared part listing visible on UK and US Philips pages, not confirmation of local stock or plug/electrical equivalence.

Dyson's US parts page lists this Combi filter for the named TP, HP, PH and BP machine families. The source is a manufacturer compatibility catalog rather than a third-party marketplace cross-reference.

Dyson lists distinct filter designs for other machines and generations. Treat this as only the named Combi filter group; confirm complete model code on Dyson's current parts page.

Coway names a dedicated Airmega 100 Filter and describes it as the Airmega 100 replacement filter. The manufacturer identifies a combined vacuumable pre-filter, HEPA filter, and deodorization filter.

US-source evidence only. The checked storefront page states shipping to the 48 continental US states; it does not establish local fitment, stock, delivery, or warranty in Canada or the UK. No SKU was shown on the reviewed filter page. Aftermarket fit and performance are untested.

Levoit identifies this genuine replacement filter for the Vital 200S-P series. The page lists Pet Allergy, Smoke Remover, and Toxin Absorber choices as separate specialty filter options; this record does not equate them to a shared part SKU.

Keep the complete -P suffix. US-source fit statement only; no Canada or UK fitment or availability is established. Confirm any specialty option and its part identifier on Levoit's current page. No aftermarket fit or performance is established.

Levoit states this replacement filter is compatible only with the EverestAir-P purifier and lists the filter model as LRF-E551-WUS.

Keep the -P suffix. US-source fit statement only; no Canada or UK fitment or availability is established. Do not extend this match to an EverestAir model without the P suffix or to other purifier generations. Aftermarket fit and performance are untested.

The 9800 manual names Filter A / SKU 115115. WINIX separately lists a Filter A +AllergenGuard annual set, SKU 1712-0004-10, as compatible with 9800. This is a separate product/set identifier, not an alias for or proof of equivalence to SKU 115115.

US-source evidence only; no Canada or UK fitment or availability is established. The annual-set page supports only its own distinct SKU. Do not merge the two identifiers. Aftermarket fit and performance are untested.

Guardian Technologies' Filter B page explicitly lists the full AC4300BPTCA model code as compatible with FLT4825. The separate AC4300 family page lists other Filter B variants, but does not establish those variants for this exact CA-suffixed model; this row records only FLT4825.

The exact compatibility line comes from a US manufacturer page despite the CA suffix. It does not establish Canadian stock, shipping, warranty, or a Canada-market fit source. Do not extend this exact mapping to other Filter B variants. Aftermarket fit and performance are untested.
