On a daily driver they are of little or no benefit, and are not cost effective. They provide no noticeable increase in performance or mpg. In racing applications they do improve performance. They increase air flow in the very upper rpm ranges.
It also depends on what type of K&N air filter you get, if you spend the money on a cold air intake you will get better MPG on the highway and you will get more horsepower. If you get one of their stock replacement air filters it won't be as noticeable but you will be able to keep that for the rest of the cars life and instead of replacing it you can just hose it off.
K&N filters use oil to trap particles, which relative to the size of dust particles is similar to glues. They are also reusable by cleaning them with a hose, allowing them to dry, then reapplying the filter oil. The above posters are correct in that the filters make a negligible difference with typical driving; the change in drag is the square of the change in airflow speed.
And they make you burn through more fuel, especially if you have a stock CPU and it feeds more air through the intake system the CPU needs to balance the fuel to air ratio hence using more fuel to catch the increase of air introduced into the system.
K&N air filters can be purchased both online and in stores. Stores such as O'Reilly Auto, K&N Store, KN Filters, Amazon, and 4 Wheel Parts all sell K&N air filters.
First check with KN filters if they have any for your vehicle. If not you can always cut or drill a hole into the factory one and bolt it on.

A carbon air purifier filters and cleans the air by absorbing odors and other gases that are too small to be trapped by other filters. These are often used as an 'add-on' filter.
That is a bunch of BS. It also like when they say that the K&N filter will void your warranty. It wont! Opinion: As a mechanic, i do not like k&n filters. People do not maintain them and too much dirt gets in the engine, which will damage the engine.
The primary purpose of air filters is to keep the blower and evaporator coil clean. You should clean your A/C filter often to reduce unnecessary energy consumption.
The use of air filters is to clean the environment or the air. The air filters are effective in getting rid of material such as dust, bacteria or pollen form the air.
Ionic air filters work by helping to clean the air, and keep all the dirt and dust trapped inside. The filter allows clean air to escape through, and keep the air healthy to breathe.
You can use a Fram filter number PH6017A, a K&N filter number KN 303 - KN 303C or equal filters from other producers.

Air conditioning filters have to be cleaned at least every three months. Dirty air conditioning filters can increase energy consumption of air conditioners.
HEPA, or "high efficiency particulate air" filters work by trapping particles that other types of vacuum filters would let back out into the air. These filters are beneficial because they capture dust particles and debris that would slip through other types of filters, meaning that they clean better than others.
Someone can purchase Hunter Air Purifier filters online from a number of websites. One can find them for sale on 'Amazon', 'Lowe's', 'Filters USA' and 'Air Filters Now'.
think of it as light penetrates glass, but air can't The filter permits air to go through, but not dirt and dust.
Hepa filters work quite well. Ionizers work too, but are not nearly as efficient.
Holmes air filters can be purchased from the Holmes website or any store selling this brand of air filters. Most hardware stores and places such as Home Depot and Amazon sell this brand of air filters. You can check online or in your local directories.
Air conditioner filters are available for purchase inexpensively at home improvement stores such as Home Depot, Lowes, and Sears. There are also many websites that exclusively sells them, such as Discount Filters, Factory Direct Filters, Buy Filters and The Air Filter Store.
A KJ is a unit of work, whereas a KN is a unit of force. Work is force times distance, so the two units are related by the expression 1 KJ = 1 KN*m. So, if you want to know how many KJ are in 1 KN, you need to know the distance your force caused your object to travel. For example, if 1 kN caused something to travel 4 m, then (1*4) = 4 KJ of work were done on that object. Or something like that :)

Many companies manufacture allergy free air filters for different purposes. Some places to look for these products are Filtera, Lowe's, Air Filters Delivered and Clean Air Plus.

Electrostatic air filters are typically rectangular in shape and about an inch or a little less thick. The secret to their effectiveness is the polyurethane and polypropylene blends used in the filtering material. The fibers have been formulated so that when air passes by them, they generate strong static charges, catching all of the unwanted things out of the air and filtering it.
Compressed air filters, which are also known as in-line filters, serve the purpose of filtering contaminants, such as dust, oil and moisture, from air after it has been compressed. They are usually used in industrial applications.
One can purchase carbon air filters at an online retailer such as Amazon or eBay. Alternatively, one could purchase carbon air filters directly from a specialty website such as HTGSupply.
