Wish they were individually wrapped. *by C***C on Reviewed in the United States on March 18, 2022* Received a box of 6 as advertised. The size was perfect for my hard to find filter size. They come in a box with all 6 filters placed inside, BUT not individually wrapped in plastic. Therefore, when storing they are susceptible to dust, and bugs. Hard to store in an area that is clean until use. I wish each filter was wrapped in plastic as they are in the store. Will consider this when repurchasing. I did not want to purchase from Carrier, so bought in bulk. Huge downside lacks individual wrapping. Fast delivery. ### ⭐⭐⭐⭐⭐ Great filter at a reasonable price! *by G***L on Reviewed in the United States on August 12, 2021* Really like the construction and materials used for these filters. They may seem a little pricey but I couldn't find any comparable at a better price. Time will tell since I just installed one. ### ⭐⭐⭐⭐ Reasonable filters *by D***E on Reviewed in the United States on March 3, 2021* These are just what you would expect. Reasonable filters that are the size indicated. Seem to work fine. --- ## 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.it/products/199000917-16-3-8-x-21-1-2-x-1-carrier](https://www.desertcart.it/products/199000917-16-3-8-x-21-1-2-x-1-carrier) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-09*
