As of 2-26-2020, the description for this product on Amazon absolutely says "True HEPA". It reads: "Alen Replacement Air Filter for BreatheSmart Classic, True HEPA VOC Filter for VOC's, Smoke, Chemicals, Allergies, Pollen, Dust, Dander and Fur by Allen." I originally purchased this product, believing that it had a "True HEPA" filter. If there is a difference between "True HEPA" and True HEPA VOC," then that difference needs to be clarified. **Q: What is the smallest particle in micron size that this filter will capture?** A: Dear Scooby,Thank you for reaching out to us.The smallest particle that the Alen BreatheSmart Silver Carbon Filter will pick up is down to .3 microns. That's fine enough to capture bacteria and many viruses. Super fine dust of any kind is 2.5 to 10 microns.Should you have further questions or concerns, please don't hesitate to contact us.Thank you for choosing Alen as your clean air provider and have a great day.Best Regards, JanellynAlen Dealer and Marketplace Coordinator **Q: Why do you tell me that my order will be delivered on the 28th, then the 29th, then the 30th and now Nov. 1st? My confidence in Amazon is waning!** A: Appears to be like this everywhere. Staffing shortages everywhere. Relax. **Q: These say they capture voc, but why is there a bf35-voc is these handle them?** A: Dear Mr. Timothy R. Zuidema,Thank you for reaching out to us.Both BF35-Silver-Carbon and BF35-VOC replacement filters capture VOCs (Volatile Organic Compounds) from cleaning products, personal care items and other household materials. Their differences are: BF35-Silver-Carbon has 1.5lbs activated carbon reducing light odors and chemicals commonly found in the air from cleaning products, smoke, cooking, pets and various other household materials. The BF35-VOC on the other hand, has 3lbs activated carbon reducing odors and chemicals commonly found in the air from cleaning products, smoke, cooking, and various other household materials.Should you have further questions or concerns, please don't hesitate to contact us.Thank you for choosing Alen as your clean air provider and have a great day.Best Regards, JanellynAlen Dealer and Marketplace Coordinator ## Frequently Bought Together - Alen Air Filter BF35-Fresh Replacement HEPA Filter for BreatheSmart Classic Air Purifier - Captures Allergens, Dust, & Mold + Odors & Smoke (1 Filter) - Alen Air Filter B4-Pure Replacement H13 True HEPA Filter for BreatheSmart 45i & Flex Air Purifier - Captures Allergens, Dust, & Mold (1 Filter) - Alen Air Filter TF60-Pure Replacement HEPA Filter for T500 Air Purifier - Captures Allergens, Dust, & Mold (1 Filter) --- ## 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.tn/products/297226689-air-filter-bf35-fresh-replacement-hepa-filter-for-breathesmart-classic](https://www.desertcart.tn/products/297226689-air-filter-bf35-fresh-replacement-hepa-filter-for-breathesmart-classic) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-05-25*
