EXPLORE THE BENEFITS OF K&N AC AND FURNACE FILTERS
WASHABLE & REUSABLE
Installing a washable, reusable air filter can help save you money over disposable filters—which must be frequently repurchased (approximately every 90 days in the average suburban home, and every 60 days or sooner if you have pets). Instead of fully replacing your filter several times a year (which can be very costly), simply wash and reinstall your new K&N® lifetime washable home air filter in your cooling and heating system.
HELPS IMPROVE AIR QUALITY
A high-quality air conditioner and furnace filter can help maintain high-quality indoor air, and each K&N lifetime washable home air filter is engineered to provide exceptional capturing capability for airborne contaminants such as bacteria, mold, spores, dust mites, and carpet fibers—and helps protect your family from allergens including pollen, pet dander, and dust.
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.
DIRECT REPLACEMENT
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.
EASY 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.
BREATHE CLEANER AIR IN YOUR HOME
You may not realize that the air inside your home can be even dirtier than the air outside in the environment, and a high-quality air conditioning and furnace filter can help improve the quality of the air that you breathe! Each K&N lifetime washable home furnace filter is engineered to provide exceptional capturing capability for airborne contaminants such as bacteria, mold, spores, dust mites, and carpet fibers—and helps protect your family from allergens including pollen, pet dander, and dust.
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.
