Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Meet the Filtrete Allergen Defense 16x25x4 pleated air filter, a purpose-built solution for cleaner indoor air you can feel. This 4-inch-thick filter uses electrostatic, pleated media to create a large filtration surface that captures a broad spectrum of common irritants, helping you breathe easier every day.

  • 1000 MPR filtration — a high-efficiency rating that targets microscopic pollutants while preserving strong airflow for your furnace or HVAC system.
  • Comprehensive pollutant capture — designed to filter bacteria, pollen, smoke, viruses, mold spores, dust, and lint, addressing allergy symptoms and irritants from everyday living and urban environments.
  • Pleated media with electrostatic charge — enhances particle attraction and retention without sacrificing system performance.
  • Solid, cardboard frame for reliable installation and stable airflow paths; trimmable: No, this filter is sized for a precise fit.
  • Single-pack convenience — sold as one filter, specifically part of Filtrete’s Allergen Defense line to deliver dependable, room-to-room air quality improvement.

sized to fit standard 16x25x4 filter slots, with precise actual dimensions of 15-7/8 in x 24-5/9 in x 4-1/3 in (nominal 16x25x4). The Allergen Defense line is crafted for homes where air quality matters—from families with kids and pets to urban dwellers exposed to smoke or seasonal pollen. If you’re seeking a practical upgrade over basic filters, this model provides noticeably stronger protection against everyday allergens while maintaining efficient airflow through your HVAC system.

Why choose this filter? It’s built to address the irritants that affect comfort and health in real-life living spaces. With its combination of pleated media, electrostatic filtration, and a focus on allergens and fine particles, it’s a clear choice for those who want clearer air without compromising system performance. Whether you’re tackling seasonal allergies, reducing household pollutants, or simply aiming for a healthier home environment, the Filtrete Allergen Defense 16x25x4 is engineered to help you breathe easier day after day.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a co-op banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
