Introducing Lifetime Washable Home Air Filters from K&N

Installing HVAC Filter

K&N HVAC filters are designed to provide outstanding filtration and dust capacity for long-life performance, and are specially designed to help reduce contaminants in the air you breathe. Even better, they can be cleaned easily for years of use in your home, office, or business.

Why choose a K&N HVAC filter over a disposable filter?

• Your HVAC system might be working harder than it should be. A dirty filter can slow airflow and affect the performance of your HVAC system, which must work harder to maintain environmental temperature.

• Dirty air filters can be a source of contaminants and bacteria. An overloaded filter can be a breeding ground for fungal spores, which can then be released into the air you breathe.

• Disposable filters need to be replaced approximately every 60-90 days. Instead of regularly discarding and purchasing filters, one K&N lifetime washable home air filter is designed to last for years.

• Over fifteen years, the average person is likely to purchase 60 disposable filters or more*—but each K&N HVAC filter is protected by a Lifetime Limited Warranty.

Each K&N HVAC filter comes with K&N's Lifetime Limited Warranty


Disposable HVAC filters must be frequently replaced—approximately every 90 days in the average home, and every 60 days or sooner if you have pets or allergy-sensitive people in your home. The number of occupants in your home, pets, and environmental factors all play a role in the speed at which your filter becomes dirty. K&N lifetime washable home air filters help capture dust, pollen, bacteria, spores, allergens, and other contaminants, and are simple to clean and reinstall. Instead of fully replacing your filter several times a year, you can simply wash and reinstall your K&N HVAC filter whenever it becomes dirty.


You may not realize that the air inside your home can be even dirtier than the air outside in the environment! In North America, adults spend approximately 87% of their time indoors. Studies performed by the EPA have shown thatlevels of many common pollutants are 2 to 5 times higher indoors than outdoors—regardless of whether homes are suburban or rural. 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.

After you rinse your K&N HVAC filter, simply allow it to air dry before reinstalling


High airflow helps reduce HVAC system strain and requires less energy, which can translate to savings for you! When a filter becomes extremely clogged (or you purchase a thick disposable filter that provides low airflow), your HVAC system must work harder to compensate. When your K&N HVAC filter is dirty, you can simply clean and reinstall to help keep your HVAC system running smoothly without breaking the bank.


K&N lifetime washable home air filters are guaranteed to last—with a durable frame constructed of extruded ABS polymer, and a washable synthetic air filter media designed to be cleaned and reused as often as necessary. Over 15 years (the average lifespan of an HVAC system), the average homeowner is likely to purchase approximately 60 disposable filters (based on a filter replacement every two months). Assuming a disposable filter cost of $5, that adds up to a whopping $300 in filters, or $600 if you purchase a $10 disposable filter! Add to this the time and inconvenience of dozens of trips to the store and having to remember what filter size to buy, and your K&N washable home air filter can save you time and money over the life of your HVAC system.

Enjoy convenience and long-term cost savings with the filter that is engineered for long-life performance—your purchase is protected by K&N’s Lifetime Limited Warranty!


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


Washing your K&N lifetime washable home air filter is as simple as removing your filter from its housing, spraying on K&N HVAC filter cleaner (part no. 99-6010), and rinsing with a low-pressure hose! The use of any other cleaning solution can void the filter's warranty, and could quite possibly damage the filter material. 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.
