It effectively traps odors and airborne particles, ensuring a cleaner indoor environment while being eco-friendly and easy to maintain. ## Description The Blue Pure 121 Extra Protection Particle and Activated Carbon Replacement Filter protects against both gaseous and particulate contaminates. A layer of activated carbon pellets remove harmful gaseous pollutants such as volatile organic compounds (VOCs), tobacco smoke, and other stronger odors up to 2x faster. In addition, advanced polypropylene filter media removes particle pollutants down to 0.1 micron in size from your indoor air, such as pollen, dust, and pet dander. Using a 360-degree air intake and up to 4 times the filter surface area than competing replacement filters, the Blue Pure 121 Extra Protection Particle and Activated Carbon Filter lasts longer, on average from 6 months to a year.

There are some off brands out there that have poor reviews, so do your homework. ### ⭐⭐⭐ 3.0 out of 5 stars Reasonable, but I am still periodically sneezing. *by D***D on Reviewed in the United States on August 18, 2022* Given my sneezing is persisting, I will likely not again spend the premium dollars for this ‘Extra Protection’ filter. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars This filter provides clean air! *by D***G on Reviewed in the United States on April 8, 2022* It's a little expensive, but does seem to last > one year. Old one was definitly clogged with fine dust and dirt. I highly recommed using these under you main return vent. --- ## 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.be/products/537078880-blueair-blue-pure-121-genuine-replacement-filter-extra-protection-particle](https://www.desertcart.be/products/537078880-blueair-blue-pure-121-genuine-replacement-filter-extra-protection-particle) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-04-22*
