Is Your Home Air Filter Dirty? | How to Keep Your Home Air Cleaner

Keep Your Home Air Cleaner with K&N

Did you know that the air inside your home can be even dirtier than the air outside? Some studies have shown that indoor air is significantly more polluted than environmental air. Maintaining your home air filter can help preserve the quality of your indoor air, and can also help your heating/cooling system run more efficiently.

What does an A/C filter do?

While home air filters are often called many different things—furnace filters, HVAC filters, and A/C filters, to name a few—they all serve the same purpose, which is to filter your home air as it comes through your heating and cooling system. The filter helps remove particulate matter from the air, including dust, pollen, and germs—but not all filters are created equal, so it’s important to buy one that is good quality.

Where does my furnace filter go?

You’ll most often find your home air filter/furnace filter housing on either a ceiling or in a hallway. 

Do washable home air filters really work?

K&N now offers an innovative new product—washable home air filters. Each K&N lifetime home air filter is engineered to help capture 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. And they really work—extensive testing has shown that K&N home filters are more efficient than many disposable alternatives.

Why choose a K&N washable home filter?

Your HVAC system might be working harder than it should.

A dirty filter can slow airflow and affect the performance of your HVAC system, which must work harder to push air through a clogged filter to maintain environmental temperature. If the filter is too restrictive, it can even permanently damage your HVAC system. High airflow helps reduce HVAC system strain and requires less energy, which can translate to savings for you!

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.

K&N home air filters are guaranteed for life*. Now you can avoid the inconvenience of rushing out to purchase yet another disposable filter every three months; instead, all you have to do is wash and reinstall your K&N filter whenever needed.

You can wash and reuse your K&N home filter as often as necessary.

The number of occupants in your home, pets, and environmental factors all play a role in the speed at which your filter becomes dirty. Now you can easily clean and reinstall your filter whenever needed, without the guilt of constantly throwing away disposables.

How do I clean a washable K&N home filter?
