HELPS INCREASE HVAC EFFICIENCY

High airflow helps reduce strain on your heating and cooling system and requires less energy, which can translate to savings for you! When a filter becomes extremely clogged, airflow through the filter begins to slow, which can force an HVAC system to work harder to compensate. Replacing a disposable filter every 60-90 days can be inconvenient and expensive—instead, you can simply rinse clean your K&N lifetime washable furnace filter to help keep your HVAC system running smoothly.

EASY TO INSTALL

Each K&N washable home air filter is designed to fit directly into your heating and air conditioning filter slot just as easily as a typical disposable air filter, with multiple dimensions and sizes available for easy installation.

SIMPLE TO CLEAN

Washing your K&N washable air filter is as simple as removing your filter from its housing, spraying on K&N home air filter cleaner (part no. 99-6010), and rinsing with a low-pressure hose! After your filter is dry, simply reinstall to enjoy the benefits of K&N’s industry-leading washable filtration technology. See the full instructions included with your filter for details.
 
Replacing your AC/furnace filters with better-performing and durable filters may also help increase energy efficiency. A dirty air conditioner filter may restrict airflow to the point that the A/C motor is stressed, so installing a K&N home air filter may help your HVAC system run more effectively. Choose the right size for your air conditioning register, and start enjoying the benefits of fresher home air.

OUR STORY
WHY K&N?
K&N is the home of the original red oiled air filter. In the early 1960s, two motorcycle racers, Ken Johnson and Norm McDonald (K&N), developed a ground-breaking new idea for an oiled air filter. Five decades later, K&N® is still innovating industry-leading filtration technology, and offers outstanding protection for everything from top-fuel dragsters to commuter vehicles across the globe. Thank you for helping us reach 50 years in business!

Improve Vehicle Performance

K&N premium aftermarket performance products help your car, truck, motorcycle, dirt bike, or ATV perform its best—helping you obtain improved power and an enhanced driving experience from your vehicle. You’ll enjoy increased horsepower, torque, and acceleration—all from the vehicle you already own.

Love Your Car, Love the Environment

Over 100 million disposable air filters end up in landfills each year. Choosing a washable, reusable product that lasts for the life of your vehicle helps to reduce unnecessary waste.

Protect critical systems

When using a poorly-designed disposable air filter, dust, dirt, and contaminants can make their way into your engine—causing damage and premature wear. In addition, an inefficient oil filter can allow oil contaminants to build up within the engine, reducing its working lifespan. K&N performance protection products are designed to keep contaminants where they belong—out of your engine.
