New Exciting Filtration Products For Your Home

WASHABLE & REUSABLE
You deserve to live in a home with clean air. As an industry leader in washable filtration and technology, you can trust K&N’s home air filters to provide exceptional capturing capability for airborne contaminants. Go ahead and replace your old AC/furnace filter with one of K&N's easy-to-install lifetime washable models and breathe easier knowing you’re helping improve indoor air quality in your home.
Cleaning is simple — just apply filter cleaner and rinse with low-pressure water. 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.

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

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.

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.
