Dimensions: 16 x 48 inches Review: Good for DIY Filters for Vacuums | Back and Front Adhesion Issue - Excellent for cutting to size filters to decrease/eliminate fine dust being blown into the air near the vacuum. This is actually an issue with most vacuums; not good for breathing or maintaining a good indoor air quality. Specially for stick vacuums (in my case featherlight model by Bissell) that offer the advantage of reusable affordable filters, compact size and excellent functionality, what they come with do not filter everything or better said do not offer sealed vacuuming. The exhaust air ejects some of the fine particles out with it. By layering a cut to size filter from this sheet behind the existing filter, you literally eliminate most if not all if it. In this way, I was happy to keep my existing vacuums without having to invest in bigger, bulkier, expensive units that require frequent filter change to offer sealed vacuuming. I confirmed this using an air quality detector that particles do not get into the air from the exhaust air vs. without. The only complaint is that the sheet has a back and front side. When cutting, they can come apart at least partially. It still holds together fine. Review: A HEPA filter pre-filter! - One reviewer is concerned that theirs came in a package marked N95 and not MERV 16. Mine says MERV 16 and nowhere is N95 mentioned but I looked up the micron ratings for both. MERV 16 has a micron rating of 0.30-1.0 greater than or equal to 95% & N95 respirators have filtration efficiencies for particle size (0.1 to 0.3 micron), of at least 95% efficient at that size. If he actually did get N95 material it's a slight upgrade to MERV 16! Either way I'm happy with my purchase. I'm building a portable positive pressure clean room using a 10x7x7 greenhouse ($75 on desertcart!) sealed to a 12x8 heavy duty tarp and for the positive pressure I'm using 2 HEPA air cleaners with medical grade filters on the outside and rigged to a 1000 CFM air blower on the inside with 4" aluminum duct work. I replaced the broken fan in 1 of them with a 325 CFM inline fan. Both of the HEPA units have modified output directly into a 4" Y connector and their combined output from outside the tent goes through a 4" semi rigid aluminum dryer vent hose to a T connector hooked to both intakes on the sides of the blower. So the combined purified air is basically sucked in through the ductwork and through the blower into the lab inflating it and giving positive pressure meaning when I unzip the door a blast of pure air comes out and it reinflates after I zip it shut. This is lab #4 for me. Inside the big tent I'll have a 6'x6'x6' small one with a fat Laminar flow HEPA filter to do my tissue culture work in. The point is I need the purest of air and I think using this MERV 16 fabric as a pre-filter for my external HEPA filters is going make a world of difference for the lifespan of the system. The truth is I worked in a clean room before and the technician explained that the more junk that collects on the outside of the HEPA filters is the better they filter because the dirt acts like a pre filter and that's why professional cleanrooms never change their filters. The 1000 CFM blower is to negate the loss of output usually caused by the filters in the home HEPA units. Those I won't even need to turn on but probably will for that little extra boost. These MERV 16 filters combined with the HEPA's and a few negative ionizing units I'm splicing into the ductwork means I don't have to worry about contaminants destroying $1000's worth of liquid mushroom cultures anymore. In the past people would step into my lab and not want to leave. Suddenly their allergies were gone. So this long winded customer is satisfied with the price, potential and quality of this product. ## Features - Cut to fit and create your own perfectly sized air filters - Dimensions: 48 x 16 inches - MERV 16 - Proudly Made in the USA ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B089MDPCV8 | | Air Filter Construction | Pad/Roll | | Best Sellers Rank | #833,542 in Home & Kitchen ( See Top 100 in Home & Kitchen ) #465 in Air Conditioner Replacement Filters | | Brand | BIODEFENSOR | | Brand Name | BIODEFENSOR | | Common Applications | Appliances | | Compatible Devices | Air Purifier | | Customer Reviews | 4.2 out of 5 stars 584 Reviews | | Item Dimensions L x W x Thickness | 48"L x 16"W x 0.04"Th | | Item Weight | 8 ounces | | MERV Rating | 16 | | Manufacturer | Biodefensor | | Manufacturer Part Number | BIO-M16-4816 | | Material | Polyester | | Material Type | Polyester | | Model Number | BIO-M16-4816 | | Number of Items | 1 | | Number of Packs | 1 | | Product Dimensions | 48"L x 16"W x 0.04"Th | | Product Grade | new | | UPC | 012436463168 | | Unit Count | 1 Count | ## Product Details - **Air Filter Construction:** Pad/Roll - **Brand:** BIODEFENSOR - **Compatible Devices:** Air Purifier - **Item Weight:** 8 ounces - **MERV Rating:** 16 - **Manufacturer:** Biodefensor - **Material:** Polyester - **Number of Items:** 1 - **Product Dimensions:** 48"L x 16"W x 0.04"Th - **UPC:** 012436463168 ## Images ![Biodefensor MERV 16 Air Filter Material Roll - Made in USA - DIY Filtration Projects - Image 1](https://m.media-amazon.com/images/I/71RTADcYIuL.jpg) ## Questions & Answers **Q: Is the certified Merv 16? If so what certification does it have?** A: Hello, good question. Yes it is Certified MERV 16. See below: EFFICIENCY RATING: MERV 16 per ASHRAE 52.2 ISO 16890 ePM10 94% ePM2.5 90% ePM1.0 79% **Q: Seller states above that "we use multiple layers of non-woven polypropylene polycarbonate (nwpp) material...." is this product polypropylene or not?** A: Hello, this filter media is made using premium polycarbonate. All sourced here in the U.S. We only use polycarbonate, specifically nonwoven polyester polycarbonate (NWPP) because of its characteristics and structure making it ideal for face mask filters. Polypropylene is very air flow restrictive, making it difficult to breath, not a good choice for face mask filters, it should only be used if no polycarbonate material is available. Polycarbonate is much more superior, specifically nonwoven polyester polycarbonate (NWPP) making it highly efficient Merv16 that blocks the tiniest particles up to 0.3 microns with low air flow resistance, this makes it a perfect filter material for face mask for all day comfort and easy to breathe through. Thank you for your question. Be safe! Warmest regards, Biodefensor Filters **Q: What is the difference between your Merv 13 v Merv 16 if both have the same minimal filter particle size of 0.3 microns?** A: Merv13 means the filter will trap less than 75% of air particles from 0.3 to 1.0 microns. While Merv16 means the filter will trap 95% or more of air particles from 0.3 to 1.0 microns **Q: What is the filteration efficiency of this material in 0.3um-1um range?** A: Note that the manufacturer's own answer to this question (in which they claim 79% efficiency in the 0.3um-1um "E1" range) classifies this filter as MERV 14, not MERV 16. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good for DIY Filters for Vacuums | Back and Front Adhesion Issue *by S***N on March 23, 2022* Excellent for cutting to size filters to decrease/eliminate fine dust being blown into the air near the vacuum.

It may be suitable for mechanical air flow and ventilation. This filter blocks most of air flow. Therefor, you should be careful when using it for natural ventilation. So, I think consumer users should not use this filter for natural air flow. ## Frequently Bought Together - Biodefensor MERV 16 Air Filter Material Roll - Made in USA - DIY Filtration Projects - Merv 13 Filter Material for Air Filters (16Ft²) , Air Particles, Clean Living Basic Dust Small as 0.3 Microns, Efficiency Breathable DIY Design (16 Square Feet) - NORTHWEST ENTERPRISES MERV 13 Filter Media, Cut to Fit, Washable Air Filter (24" x 96" x 1/16") --- ## 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.pt/products/216298421-biodefensor-merv-16-air-filter-material-roll-made-in-usa](https://www.desertcart.pt/products/216298421-biodefensor-merv-16-air-filter-material-roll-made-in-usa) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-08-31*
