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.
