Review: OEM filters are the best! - Excellent quality air filter. It's always good to use OEM filter. Review: Worth the extra money - We have a Blueair filter and these are the best priced filters I’ve found. Have them set for automatic delivery every six months so I don’t have to think about my air filter ever which is really nice. It’s constantly running in our bedroom and with two large dogs and a husband with terrible allergies, it’s been great for us over the last 8 years. Tried to use generic filters once and they didn’t fit correctly and didn’t work nearly as well. Pay the money and get the better product for this air filter. ## Features - UPGRADE to previously offered SmokeStop filters, designed for ultimate particle gas and odor removal with no reduction of CADR - DUALPROTECTION with activated coconut carbon layer which naturally removes odor causing VOCs and smoke while particle filter captures pollen, dust, pet dander, mold spores, viruses and bacteria* - UP TO 4x FASTER pollutant removal than other carbon filters - GENUINE Blueair Replacement Filter is compatible with Blueair Classic 402, Blueair Classic 403, Blueair Classic 410, Blueair Classic 450E, Blueair Classic 455EB, Blueair Classic 405, Bluair Classic 480i - RECOMMENDED to change filter once every 6 months ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07KQZY8YL | | Batteries required | No | | Best Sellers Rank | #187,788 in Home & Kitchen ( See Top 100 in Home & Kitchen ) #1,352 in Air Purifier Filters | | Customer Reviews | 4.6 4.6 out of 5 stars (218) | | Item Weight | 13.4 ounces | | Item model number | 402 DPF | | Manufacturer | Blueair | | Product Dimensions | 20.5 x 9.8 x 3.7 inches | ## Product Details - **Air Filter Construction:** Pleated - **Brand:** BLUEAIR - **Compatible Devices:** 403 • 405 • 450E • 402 • 410 • 455EB • 480i - **Global Trade Identification Number:** 00689122011998 - **Item Weight:** 0.38 Kilograms - **Manufacturer:** Blueair - **Material:** Carbon Fiber - **Number of Items:** 1 - **Product Dimensions:** 20.5"L x 9.8"W x 3.7"Th - **UPC:** 689122011998 ## Images ![Classic 400 Series Genuine DualProtection Filter; fits Classic 480i, 402, 403, 405, 410, 450E, 455EB - Image 1](https://m.media-amazon.com/images/I/71FzzrgU4WL.jpg) ## Questions & Answers **Q: Why is this filter producing a smell with over 160+ days left?** A: If you are using a DualProtection (previously "SmokeStop") filter, the filter will always have a smell of burnt charcoal as long as the charcoal remains effective. While strong at first, it should soon taper off to the point where you only smell it if your nose is right at the air outlet of the unit. If you don't smell it there, then the filter no longer is effective at removing odors/VOCs. **Q: Why does this filter come in two parts (carbon can be pulled away using the cloth tab)?** A: As mentioned, original Blueair filters do not have a separate carbon layer which can be pulled off. The good news is, a separate, removable carbon layer means you can replace it when the carbon is no longer effective (which is typically much sooner than the particle filter needs replacing, so it can save you money). The bad news is, you are not using the intended Blueair filter, which means you are probably not getting the same level of filtration with the same airflow as you would be otherwise. **Q: how much carbon is in the combination filter? Blueair chat told me about 7 lbs, but that is much more than the weight of the product so am skeptical** A: There is no carbon in this filter or the ones I buy, I have in the past bought the smoke eater filter. That filter has carbon, found that the cost is not worth it **Q: On the dp filter i received, on the black metal side, it says to face the fan - is that the intake side? so left: white, right: black when cover open?** A: Years ago I was told directly by the Blueair techs in Sweden, that the black carbon side of the filter needed to face outwards, so the metal grid on the particle side of the filter faces away from the ionizer at the air inlet. Otherwise the metal grid would dissipate the charge on the particles and reduce the efficiency of the filter. If it is indeed the case now that it doesn't matter, then definitely place the filter with the carbon side facing inwards, as the carbon element clogs up with dust much quicker than the pleated element of the filter. ## Customer Reviews ### ⭐⭐⭐⭐⭐ OEM filters are the best! *by T***T on January 3, 2026* Excellent quality air filter.

I generally try to buy OEM filters given that I want to ensure a good fit and the whole purpose of buying a high quality purifier in the first place is to be effective. Only downside is that they are very expensive and feels like they are taking advantage of locked in users. ## Frequently Bought Together - BLUEAIR Classic 400 Series Genuine DualProtection Filter; fits Classic 480i, 402, 403, 405, 410, 450E, 455EB - BLUEAIR Classic 200 Series Genuine DualProtection Filter; fits Classic - BLUEAIR Classic 500/600 Series Genuine Dual Protection Replacement Filter; fits Classic 580i, 680i, 501, 503, 505, 510, 550E, 555EB, 601, 605 ( 3 pack ) --- ## 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.pl/products/95225475-classic-400-series-genuine-dualprotection-filter-fits-classic-480i-402](https://www.desertcart.pl/products/95225475-classic-400-series-genuine-dualprotection-filter-fits-classic-480i-402) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-23*
