Before buying Panasonic's FY-FST25 replacement filter, check the model number of your ventilation fan. The fan size or the filter's appearance alone cannot confirm compatibility.
Models listed for the FY-FST25
Panasonic's official product page lists the following compatible fan models. Suffixes such as “-K” and “-W” identify colour or finish variants.
- FY-25EH2, FY-25EH3 and FY-25EH4
- FY-25PH2, FY-25PH3 and FY-25PH4
- FY-25YH2, FY-25YH3 and FY-25YH4
The page describes the FY-FST25 as a two-piece resin filter and the successor to the FY-FS251. It also says to check the fan's model number before buying.
Do not assume it fits a model missing from this list just because its number includes “25.” Compare your model number with Panasonic's official product information.
Check these details before ordering
- Find the fan's model number on the unit or in its manual. If it can only be seen by removing a cover, follow the manual's instructions for checking it.
- Compare each character with the model list above. Do not substitute a similar-looking model number.
- Confirm that the listing is for the FY-FST25, and check the pack quantity and material.
- Check shipping, delivery time, stock, payment and return terms when ordering. Terms can vary by item and delivery method.
If you cannot find the model number, it is not on the list, or you cannot read it, pause the order and ask Panasonic or the shop to confirm using the model number. Do not infer fit from the outside dimensions or fan-blade diameter.
Once you have confirmed the model, you can check the seller's FY-FST25 listing at Jusetsu Pro on Rakuten.
Check the seller's terms before ordering
Jusetsu Pro's payment, shipping and return policy says that after the first 30 minutes, a buyer-requested cancellation may be requested by phone or email if shipping work has not started. An item ordered from a manufacturer cannot be cancelled after the seller has arranged it, even before shipment. For a change-of-mind return, the item must be unopened and unused, and the shop must be contacted within 14 days of delivery. This applies only to items in the shop's stock; made-to-order items cannot be returned. The refund excludes the original shipping and fees, and the buyer pays return shipping.
For a refund or exchange due to a defect, the same policy requires contacting the shop within 14 days of delivery and says the shop pays return shipping. We did not confirm whether this FY-FST25 listing will be treated as an in-stock or made-to-order item, or which delivery method and shipping charge will apply. The shop lists several delivery methods with different conditions, so check this item page and the checkout screen for the terms that apply to your order. Recheck the price, stock and delivery estimate there as well.
Check replacement timing and method separately
The official product information we checked covers compatible models, material, pack quantity and successor status. It does not, by itself, confirm when to replace the filter or how to remove and install it. Follow the manual for your fan if it explains the replacement interval and steps.
If you cannot find the manual, the part will not come off, or it is damaged, stop and contact Panasonic or your building manager. Compatibility and safe replacement are separate checks.
The product information, listed models and Jusetsu Pro's sales and return policy were checked on October 24, 2026. We did not inspect your fan or the physical item, confirm the stock category or delivery method for this order, or verify how the shop handles an individual order. We have not tested filter replacement, cleaning performance or any change in ventilation.
