HVAC Filter 14x30x1

The K AND N ENGINEERING HVAC Filter 14x30x1 is a premium synthetic reusable air filtration element engineered for HVAC systems requiring high-flow, long-service-life performance. Unlike disposable paper filters that clog and restrict airflow over weeks of use, this rectangular element delivers consistent filtration while maintaining engine breathing efficiency. Mechanics and vehicle enthusiasts who prioritize engine health and fuel economy recognize that restrictive stock filters rob horsepower and increase fuel consumption—this K&N design solves that problem with washable, reusable construction.

The 14x30x1 filter utilizes K&N's proprietary oiled synthetic media, which traps contaminants while allowing maximum air volume to pass through. Measuring 29.6 x 13.6 inches with a 0.8-inch profile, the filter's large surface area significantly reduces intake restriction compared to OEM elements. The white synthetic material is inherently washable and reusable—simply clean with mild soap and water, re-oil with K&N's service kit, and reinstall. This construction extends filter life to 50,000+ miles in normal conditions, reducing replacement frequency and long-term maintenance costs while maintaining superior filtration efficiency.

This HVAC filter suits vehicle owners and fleet operators seeking to reduce intake restriction and improve engine responsiveness without sacrificing air quality. The 14x30x1 dimensions fit standard rectangular HVAC housing configurations common in many domestic and import platforms. Installation requires no modifications—drop-in replacement takes minutes. Weighing 2.9 lbs, the filter is lightweight and easy to handle during service intervals. For anyone committed to maximizing engine efficiency, reducing waste, and achieving measurable gains in throttle response and fuel mileage, this reusable filter is a no-compromise upgrade.
