Although the FDA has no health-related standards, it does consider some portable air filtration systems to be Class II medical devices. In the United States, nothing can claim this status without FDA approval. To get approval, a manufacturer must show two things: (1) that the device is safe, usually indicated by the Underwriters Laboratory (UL) seal, and (2) that it has a medical benefit. Look for both the UL seal and a statement of the FDA's Class II approval.

You should not use more than one filter in any one place in the HVAC system due the air flow restriction it imposes on the HVAC system. Consult your service manual regarding specifications for your particular furnace or air conditioning system.

The air filter is a critical component of your engine. We cannot stress enough that for proper care of your engine, the air filter must be in proper working order. The air filter in all of our Nitro kits is pre-oiled for your convenience, however it must be cleaned and re-oiled after running 2-3 tanks of fuel. To clean the air filter, take the foam filter element out of the rubber boot and use fresh Nitro fuel to rinse the dirt from the foam element.

Indoor Air Quality (IAQ) refers to the effect, good or bad, of the contents of the air inside a structure, on its occupants. Usually, temperature (too hot or too cold), humidity (too dry or too damp), and air velocity (draftiness or motionlessness) are considered "comfort" rather than indoor air quality issues. Unless they are extreme, they may make someone unhappy, but they won't make a person ill.

According to the American Lung Association, in 1999, 85% of Americans did not realize the air in their homes might be a health hazard. However, more people are becoming increasingly aware of the importance of the quality of air that we breathe indoors. We take for granted the cleanliness of our indoor air. The average person spends 90% of their time indoors, may it be at a store, bank, school, etc. therefore making it vital to our health that we are informed on improving our indoor air quality.

Yes! It will greatly improve your indoor air quality over standard fiberglass disposable filters. We feel that AIR KONTROL ELECTROSTATIC FILTERS are the best washable air filter solution to better indoor air quality.

To keep your furnace and air conditioner operating at peak efficiency. When the heat transfer surface of the furnace and air conditioner (indoor evaporator coil located on top of your furnace) gets covered in dirt (dust, etc...), it requires more energy to achieve the same load. For heating, this means you will consume more gas and electricity to heat your home, and for air conditioning, you would use more electricity to cool your home.

Look for the arrow showing airflow direction on the old air conditioner furnace filter and remember which way that it points. Make sure that you turn off your HVAC system to stop the airflow. Remove the old air conditioner furnace filter and discard it carefully so you don’t put the dust and other airborne contaminants back in the air. Write the date you install the air conditioner furnace filters on the place indicated on the side of the air filter frame.

If you have not experienced a decrease in mileage or engine performance, chances are your filter is fine and does not yet need cleaning. To be more specific, the filter does not require cleaning if you can still see the wire screen on the entire air filter regardless of how dirty it may appear. When the screen is no longer visible some place on the filter, it is time to clean it.

No. An engine can only draw in a certain volume of air depending on the engine’s size (measured by such things as bore, stroke and number of cylinders). Vehicles are designed to accommodate large changes in air pressure so they can operate at sea level or at an altitude of 14,000 feet. Engine computers adjust the amount of fuel required as a result of changes in air pressure (density).

K&N has an active Custom Air Filter Program to meet the needs of consumers with special filtration needs. We offer thousands of possible configurations of custom filters, in different shapes, dimensions and heights. Click here to read more.

Use a K&N Filter Care Service Kit, available at all major auto parts stores and a low pressure nozzle-free garden hose. A filter cleaned with K&N cleaning products will ensure a lifetime of performance from your air filter. Instructions for cleaning your K&N air filter are on our Air Filter Cleaning Instructions page.

No, this can blow the filter material right out of the wire mesh and ruin the filter. Pick a nice day to clean the filter and let it dry naturally. A low pressure air flow such as from an industrial drying machine or blow dryer will help the filter dry more quickly.

Air purifiers take out a lot of the pollutants from our air which can irritate allergies and asthma. These pollutants include airborne particulate as small as 0.3 microns and includes pollen, dust, pet dander, mold spores and smoke.

Wildland fires occur naturally and are one of the many natural sources of particulate matter (tiny particles such as dust, soot, etc.) Particulate matter is the main pollutant of concern from smoke because it can cause serious health problems. Smoke can also adversely affect the clarity (visual range) of our air. Wildland fire is also part of the natural ecological process of many ecosystems.

No building is perfectly sealed and so the air inside ultimately originates outside. Air pollution present in the outdoor environment will therefore enter into the building as well. Generally, pollutants present in the outdoor environment are present at a somewhat lower concentration than outside (probably 10 to 90% in most cases). There are several reasons for this. Some pollutants are absorbed by materials in the building. Others deteriorate or react chemically and so disappear.

The usual clue is that people feel ill while inside the building, and the symptoms go away shortly after leaving the building, or sometimes, when away for the building for a period of time (as on weekends away from work, or a vacation). This doesn't necessarily work in cases of BRI (sections 2.3, 2.4), where it may take medical testing and investigation of the building to determine whether the building is the source of the problem.

Look over this FAQ. Find the material most related to what seems to be going on. In most cases there are suggestions as to things that can checked in to. Some of these can be checked by anyone; others require an expert (medical doctor, HVAC service company, IAQ investigator, etc.).
