It’s nearly impossible to guess. I had to buy a kit at Amazon that had the blue faucet key. Lowes—where I bought my faucet—didn’t even have a key to remove the filter. The key set I bought was—JQK Cache Faucet Aerator Key for M 16.5, 18.5, 21.5, 22.5, 24. The kit was $7.99 and had a nice range of sizes. **Q: Does this come with the key?** A: Yes, the blue handle shown in the photo is used for installation or removal. **Q: Will it fit model 19950-dst?** A: The absolute best way to know if this is a suitable replacement is to remove the old part and measure with calipers or even a micrometer as shown in the seller's product description. The dimensions should come close to the product description from where you're buying the replacement part. **Q: Which of the three aerators available works for the moen Darcy model? Their website says their aerator part number is 180158** A: 18.5mm/0.72Inch --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.fi/products/161061691-faucet-replacement-part-insert-filter-restrictor-aerator-4pcs-18-5mm](https://www.desertcart.fi/products/161061691-faucet-replacement-part-insert-filter-restrictor-aerator-4pcs-18-5mm) --- *Product available on Desertcart Finland* *Store origin: FI* *Last updated: 2026-11-10*
