Fiberglass filters are the least expensive types of filters and are generally just a thin panel of woven material. They are often used in rental facilities and are available with MERV ratings between one and four, meaning they only remove the largest of airborne particles. Designed solely for the interior components of your air conditioner, these filters are generally not recommended as they will not improve IAQ and may not provide adequate equipment protection. Pleated filters are the next step up from thin fiberglass, providing a MERV rating between six and eight while still being quite affordable. The smaller pore sizes and greater surface area of these filters will help improve IAQ by removing a greater percentage of allergens, dust, dirt, lint, etc. In households without pets or respiratory sufferers, these filters are often the preferred choice as they offer adequate equipment protection while maintaining IAQ at a reasonable level.
Electrostatic filters carry an electrical charge that attracts airborne particulates, allowing them to capture and remove a much greater percentage of contaminants. Typically rated with a MERV value around 10, these filters are excellent in households with pets, smokers, or sensitive individuals that require a higher level of IAQ.
Permanent electrostatic filters offer many of the same advantages of disposable versions but can last up to eight years with regular cleaning, making them a very economical option. Their MERV ratings are often in the eight to range.
High efficiency pleated filters are available with MERV ratings up to 16, although 1is generally considered sufficient even in households with highly sensitive people. These filters will remove a large percentage of bacteria and some viruses from the air; those with ratings between 1and 1are even useful in hospital settings. Above MERV 13, air filters tend to restrict airflow within the system and can actually increase energy usage, meaning they are not ideally suited for household use.
Where is My Air Filter? How to Size and How to Replace?
Panel Air Filters
Panel air filters can be made of a variety of materials, including fiberglass and synthetic fibers. They are the traditional disposable air filters found in many home HVAC systems. They are 1-inches thick and designed to protect your heater and air conditioner by removing larger dust particles from your home’s air. However, they are not capable of improving your indoor air quality by removing airborne pollutants that cause health problems
Electrostatic Air Filters
Electrostatic air filters consist of electronically charged fibers that are designed to “magnetically” draw air pollutants out of the air. Many electrostatic air filters are washable and can last for years if used correctly. However, there are numerous different designs available, and they are not all equally effective.
Pros: Long lifespan, less waste, more efficient than traditional panel filters
Cons: Must be regularly cleaned and maintained, wide variety of designs with vastly differing efficiencies.
Electronic Air Filters
Electronic air filters are different from electrostatic air filters in that they require electricity to operate. Electronic air filters are installed in your home’s existing HVAC system and use electronic charges to collect and remove even very small airborne particles. However, not all are created equal. Some electronic air filters have been shown to emit ozone, which can be harmful. We recommend the Bioguard Powered Filter because it has no ozone emissions.
Pros: Very efficient at removing small particles, lasts for many years, very little restriction to airflow, good for allergy and asthma sufferers
Cons: Higher initial cost, best if used in conjunction with panel or other filter.
Armed with this useful information, it will be easier to decide on and find the air filter that fits your needs and HVAC system.
Home Air Filter Ratings
Mechanical air filters are the most common type of home air filters used in residential HVAC systems.
These filters use synthetic fibers to trap small particles, debris, and dust, among other things — preventing those things from circulating in the air and getting into our lungs.
The effectiveness of a mechanical air filter is measured in MERV ratings (Minimum Efficiency Reporting Value). Generally speaking, the cheaper the filter is, the lower the MERV number is. In other words, you get what you pay for. Air filters with lower MERV ratings need to be replaced more frequently.
Mechanical air filters remove dust by capturing it on the filter medium, the material that makes up the filter element. A mechanical air filter is any type of dry media filter. All of the throwaway air filters used in HVAC systems and Air Handlers are mechanical air filters. Any man made or natural fiber filter is a mechanical air filter. This includes HEPA air filters as well. Source

K&N automotive oil filters provide high flow rates while providing outstanding filtration. High filter flow rates are especially important in racing vehicles where heavier grade oil is used and the oil is pumped much faster than in a standard vehicle. K&N automotive oil filters are engineered to handle all grades of synthetic, conventional and blended motor oils
Air Filter Facts
We believe the primary function of an air filter is to deliver both high airflow and superior dirt protection. We design our air filters to provide minimum restriction allowing high airflow into an engine. In the vast majority of cases increased airflow will increase engine performance measured by horsepower and throttle response (torque). The performance benefits of maximum airflow are clear, compelling and well documented. That is why so many professional racers are willing to run expensive vehicles with no air filter, as opposed to installing a disposable air filter. They are seeking the additional horsepower and throttle response needed to win the race.
We design our air filters to provide superior filtration of the contaminants that can harm your engine while maximizing the airflow characteristics of the filter in question. The ability of an air filter to protect your engine is generally measured in accordance with testing procedure ISO 501We subject a sample of our filter designs to this test procedure using Coarse Test Dust, which includes particles ranging in size from less than 5.microns to 17microns. As a point of reference, a human hair is approximately 50 microns in diameter. The result of the above test procedure is a specific air filtration efficiency number. This efficiency number represents the percentage of test dust retained by the filter and thereby kept out of an engine. Our goal is to design our air filters to achieve maximum airflow while targeting overall filtration efficiency at 98%.
Because no two air filters are alike, the specific airflow and overall filtration efficiency will vary depending on the filter in question. However, you can rest assured that each air filter we sell, has been designed to achieve high air flow while providing superior filtration.
Both air flow and dirt protection are critical to engine performance. For this reason a consumer should always evaluate an air filter based on both its filtration efficiency and air flow capabilities. It is very easy to design an air filter that exhibits high airflow simply by reducing its filtration to unacceptable levels. As the “look” of a K&N air filter has become popular, many companies have begun offering products that copy that “look.” While imitation is said to be the sincerest form of flattery, our own testing has shown that many of these look-alike products do not provide a safe level of engine protection.
Filtration 10- A Deeper Cut
Most people believe that all air filters function on a go/no go basis where dirt particles that are larger than the openings in the filter media are trapped while particles that are smaller than the openings can pass right through. A dry paper air filter does function in this manner. That’s why paper filters are so restrictive to air flow. The openings in this type of filter have to be very small to filter efficiently.
The oiled cotton filter media used in the K&N air filter functions in an entirely different manner. There are scientific principles that determine how an air filter removes dirt particles from the air stream. The first of these principles is known as interception, which applies to dirt particles traveling with the air stream. Air flow will always take the shortest path and as the air is forced to flow around the filter’s fibers some of the particles will contact the sides of the fibers and be captured. These particles are then held in place by the oil or tacking agent in the fiber.
Another principle is known as impaction, which mostly affects larger or heavier dirt particles. Impaction occurs when the inertia or momentum of the particle causes it to deviate from the flow path. In other words the heavy particles do not follow the air stream around the filter’s fibers but instead they run straight into the fibers and are captured.
Paper vs K&N
To meet minimum filtration standards, paper air filters must be thick and/or the fibers must be tightly compressed and dense. Therefore paper elements that provide adequate filtration are more restrictive to air flow by design. Additionally, as a paper filter becomes more and more clogged, the pressure inside the filter drops while the atmospheric air pressure (approximately 14.psia at sea level) outside the filter remains the same. It’s like using your lungs to draw the air out of a plastic milk bottle. When the pressure differential becomes too great, the bottle will collapse. The same thing could happen to your paper filter, although it is unlikely. But what will happen could be just as severe. An excessively high pressure differential created by a restricted filter can literally pull dirt particles through the paper medium. In other words, the performance of a paper filter, i.e. air flow through the filter and its ability to protect your engine, DECREASES near the end of its service interval.
Washable and Reusable
All of our air filters are washable and reusable. They can be easily cleaned and oiled using our K&N Recharger kits as many times as reasonably necessary. In our testing laboratory, we have washed and re-oiled one K&N Air Filter more than 100 times and it still performed up to specification. We recommend you check your air filter every 30,000 miles, however, under most street conditions the filter will not require cleaning until 50,000 miles of continuous use. And yes, we’ve heard the stories of customers who ran their K&N filter for 100,000 miles without a cleaning, but we believe cleaning after 50,000 miles to be the most beneficial service life without sacrificing air flow.
Off-Road and Racing Off-Road
An air filter element becomes an insurance policy when used in off-road applications. Competitors will sacrifice a high-tech engine for a chance to win a race — but to win, they must finish. If the engine ingests too much dirt and debris, it may die an ugly death before the vehicle can cross the finish line.
You might think this would be the perfect application for an inexpensive, throw-away paper filter. But remember, in competition a little extra horsepower can mean the difference between coming in first or finishing second. The air filter now becomes an important part of the performance package.
K&N air filters are designed to provide minimum restriction long after disposable air filters have begun choking an engine. In other words, due to its characteristics, the restriction of a K&N replacement filter increases at a slower rate when compared to a disposable filter, i.e. a K&N filter will last longer under the same conditions. That’s why most off-road competitors choose K&N filters.
In a hypothetical 24-hour off-road race to further the point, a properly sized K&N filter will see the racer through to the end with cfm to spare. The equivalent disposable air filter, on the other hand, will need to be replaced with a fresh element to ensure the engine has an adequate supply of air to complete the course. A K&N will provide excellent filtration without sacrificing air flow for a longer period of time — that’s performance with value.
One might consider a paved road course or oval track as a clean air zone. After all, how much dirt and debris could be hovering above an asphalt track?
Subscribing to that theory, a road racer may elect to forgo an air filter in favor of large volumes of unrestricted air. However, testing the theory using an air filter enclosed in a vented housing should dispel the myth. The filter and housing will trap particles of loose trash kicked up by other race cars during the heat of battle. Dirt, small stones and pieces of shredded rubber expelled from soft compound racing tires can be found inside the housing after even a short race. Once a driver, car owner or engine builder realizes just how much trash is thrown around during a normal race, few would expose their expensive engines to unfiltered air in future events.
Whenever possible, performance enthusiasts should install a K&N 360 degree open-element filter. A correctly sized conical or round filter will deliver virtually unrestricted air flow. And, as we have learned, providing the engine with all of the air it needs promotes optimum performance. In a high speed application, a K&N filter will straighten the air which counteracts turbulence.
Straight cut velocity stacks, for example, pose a unique problem. Exposed to the outside air, velocity stacks experience a phenomena that actually hinders performance at high speed. We are referring to stacks and air horns that protrude through the hood and extend into the air stream so the direction of the air rushing over the car is at a perpendicular angle to the length of the tube.
Air moving rapidly over these stacks create turbulence inside the opening. At high speed, the rushing air tends to create a partial vacuum inside the tube. The condition is counterproductive to air flow. The phenomena also effects open carburetors. The higher the ground speed, the greater the problem. Vacuum created by the engine is trying to coax air into the cylinders and the high speed air flowing over the open end of the stack is causing resistance.
Reversion creates other problems. In an automotive application, reversion refers to reversed air flow, or in simpler terms, it’s when air in the intake runner reverses direction for a split second. The condition is caused when a burst of pressure escapes into the intake runner from the cylinder during valve overlap.
Reversion creates resonance shock waves inside the tubes which exit the open end of the tube at various rates depending on engine speed. It has also been proven that these shock waves interfere with each other when the stacks are in close proximity.
Installing a free-flowing air filter on top of each stack or over the carburetor air horn eliminates these conditions. How? The solution is simply explained. The filter creates a plenum over the opening. Air entering the filter is slowed, smoothed and straightened. The filter then becomes an endless source of calm, clean air. Shock waves dissipate within the confines of the plenum without interfering with the shock waves emitted from an adjacent stack.
A Better Choice For The Environment
K&N cotton air filters have always been washable and reusable, designed for the life of an engine. If you assume an engine life of 150,000 miles in which a disposable air filter must be replaced every 15,000 miles, only one K&N air filter would be used during the same period in which disposable air filters were discarded. Considering there are millions of vehicles throughout the world, the volume of disposable air filters that could be eliminated from our landfills is a staggering number.
If maximum horsepower is the objective, the size and shape of the air filter element is paramount.
Let’s first consider shape. When fitting a conventional round filter on top of the engine, such as a carburetor, central fuel injection or throttle body fuel injection, we have found a large diameter, short filter will flow more air than a small diameter, tall filter. For example, a 10-inch diameter filter 2-inches tall will flow more air than a 5-inch diameter filter that is 4-inches tall. Where space permits, the height of the filter should be between 1/and 1/of its diameter.
The shape of the filter is less important if the application calls for a remote mounted filter, which includes many late model fuel injected models. Typically these vehicles will use a flat panel filter or a conical or cylindrical shaped filter with a rubber mounting flange designed to be mounted on the end of the inlet hose.
That brings us to size.
Use the formula below to compute the minimum size filter required for your particular application. The usable portion of the filter is called the EFFECTIVE FILTERING AREA which is determined by multiplying the diameter of the filter times Pi (3.1416) times the height of the air filter in inches, then subtracting.75-inch. We subtract.75-inch to compensate for the rubber seals on each end of the element and the filter material near them since very little air flows through this area.
A = effective filtering area CID = cubic inch displacement RPM = revolutions per minute at maximum power Example: A 350 CID Chevy engine with a horsepower peak at 5,500 rpm.
If you are sizing a panel filter, multiply the width of the filter area (not the rubber seal) times its length. If you are sizing a round filter, use the following formula to determine the height of the filter.
A = effective filtering area H = height D = outside diameter of the filter 3.1= pi 0.7= the rubber end caps Example:
Referencing the K&N catalog shows the proper filter for this application would be an E-1500 which is 3.inches tall. Keep in mind, this is the minimum size requirement. To extend the service interval and to provide an even greater volume of air to the engine, install the largest filter that will fit in the space allotted. If the space above the engine is restrictive, perhaps a remote filter arrangement could be used to gain space.
Off-road conditions require added filter area. A filter should be sized 1-1/to times larger than normal for any conditions that could be considered severe. In this case, the E-1500 used in our example should be replaced by an E-1120 or an E-1150. For long distance off-road events, two double-size remote mounted filters would be best.
A K&N Filtercharger is a high-performance air filter, both in terms of air flow and filtration. However, the service interval can vary widely depending on the severity of the driving conditions. The service interval can be from 100 miles in a desert-racing environment to 50,000 miles for normal street use. The proper way to determine when an air filter needs service is with an air restriction gauge. Such a device is commonly used on heavy duty trucks and construction equipment. A restriction gauge, measures the pressure differential inside and outside the filter and gives the information in different forms of measurement. As the filter collects more and more dirt, the restriction value increases. At a predetermined point or rate of restriction, the filter is serviced. The maximum allowable restriction for a K&N Filtercharger is 15″ of vacuum (water). If the restriction is allowed to go higher, the filter media might become so restricted that the element could distort allowing dirty air to bypass the filter and enter the engine. Conversely, cleaning a filter too often will shorten its serviceable life expectancy. Installing a restriction gauge will optimize service intervals and take the guess work out of your maintenance schedule.
K&N air filters are washable and reusable. They are easily cleaned and oiled using a K&N Recharger kit. They can be cleaned and oiled as many times as reasonably necessary. In our testing laboratory, we have washed and re-oiled a K&N Air Filter more than 100 times and it still performed up to specification.
When servicing a K&N filter, take care not to over-oil the element. Besides impeding air flow, excess oil can migrate into the intake system where it can coat electronic sensors, which some OEM’s claim may hinder the sensors’ operation and result in a repair that will not be covered under warranty. Although K&N disagrees with such claims, as explained in more detail on this web site, in order to avoid a dispute with an OEM over the denial of a warranty claim, we suggest that you be careful not to over-oil your K&N air filter. Never saturate the filter. If oil drips from the filter, wash it and start over. Use only K&N oil. For example, an E-1500 filter has 92.4-inches of surface area requiring 1.70fluid ounces of oil. Follow oiling instructions included with your filter or refer to the instructions listed here.
Emission Warranties on New Vehicles
THE MYTH: A manufacturer’s new-vehicle warranty is automatically voided once an aftermarket part (non-original equipment) is installed.
THE TRUTH: Rarely does the use of aftermarket parts violate a new-vehicle warranty.
THE RULES: Federal law, (the Clean Air Act), requires two emissions warranties: a “defect” warranty and a “performance” warranty. “Defect” warranties require the vehicle manufacturer to produce a vehicle which, at time of sale, is free of defects that prevent it from meeting required emissions levels for its useful life, as defined in the law. “Performance” warranties require that vehicle manufacturer make repairs – at no cost to the owner – should a vehicle fail to meet certain levels of emissions performance during the warranty period. This period ranges from years (or 24,000 miles) to years (or 50,000 miles) for most parts, and up to years (or 80,000 miles) for certain emission-controlled parts, specifically, the catalytic converter, the electronics emission-control unit and the on-board diagnostic device (check owner’s manual for specifics on your vehicle).
Consumers are protected under a parts self-certification program administered by the Environmental Protection Agency (EPA).
If a parts maker self-certifies it’s parts under this program, the vehicle manufacturer cannot void the emissions warranty even if the certified part fails and/or is directly responsible for the emissions warranty claim. In this situation, the vehicle manufacturer must arrange a settlement with the parts manufacturer, but the new vehicle warranty is not voided under the law.
If a parts maker chooses not to self-certify it’s parts, the only case where a vehicle manufacturer can void the emissions warranty is if a non-certified aftermarket part is proven to be responsible for an emissions claim.
As the name suggests, these threaded filters are designed to protect the front element of your lens from all manner of scrapes, as well as from dust, dirt, moisture and fingerprints. Because they are essentially just clear glass, they don’t have any discernible effect on the amount of light entering the lens (and therefore they don’t affect exposure time).
The rule of thumb here should be, as ever, buy the best that you can afford. Remember, the light will have to pass through the filter before travelling through the lens and onto the camera sensor, so the higher the quality of that glass, the better. Realistically, this equates to ensuring you get the sharpest pictures possible.
Ok, so these aren’t actually filters, but it’s worth mentioning a couple of accessories which come handy when using filters. First of all, filters are no good if they are dirty, so make sure you keep them perfectly clean (free from dust, fingerprints etc) right up until the time you need to attach them to the front of your lens. Dedicated pouches and sleeves are available, complete with soft, no-scratch lining. Secondly, for those occasions when you do get a mark on them, be sure to have a soft, lens-friendly cloth to hand to gently remove the offending smudge.

But Why EXACTLY should you Change your Car’s Oil Filter?
The filter sieves the oil as it is pumped all around the engine. After a while, the filter becomes stuffed with dirt, dust and worst of all, small metal particles. As such, it can no longer do its filtering job as required meaning these tiny metals or contaminants will continue circulating.
The worst happens when the iron fillings reach the crankshaft and camshaft bearings. Because, they lead to friction, which could completely damage the engine or cause it to wear out faster.
Changing the oil filter
Well, to ensure your car’s engine is working right the filter needs to be replaced after some time. The filter could only be lifted hand-tight but in most cases removing it proves challenging and can take lots of time. That is why you need the best oil filter wrench to move faster in your task.
My expert’s advice
At some point, I avoided changing the filter because untightening it proved involving and time-consuming.
I bet you are not into that “mischief” as I was, but if you are– watch out! That is not a smart move for pure car aficionados like you and me. “You need to change your filter after every oil change without fail,” that’s according to confirmed findings from one of my car experts.
The Tekton 12-inch is designed with an adjustable slip joint design and large teeth. It looks and operates exactly like pliers but its mouth is wide and the slip joint is easy to adjust. This gives the exact required grip.
The device is able to unscrew and install filters of up to 4-1/2-inches in diameter. Its grip teeth can comfortably hold even the most slippery or oil-covered filter surfaces. The good thing about the tool is that you just need to unwind the claws and press them on the filter.
The ABN oil filter wrench is equipped with the 6-cylinder that relies on or uses the cartridge style filter housing. The tool rakes it praises from working best on Toyota, Lexus and Scion 6-oil filters among other car types. It is constructed from a very strong but soft alloy to avoid cracking or damaging the cap.
The 64mm 1flute wrench is also designed for hex. And is particularly machined for cars with ordinary disposable screw canister oil filters. It engages the 6mm ring to increase its contact area, which also reduces the chances of stripping the cap. It is liked because it gives multiple contact points that securely engage the filter housing.
Air purifier sales soar as NCR chokes on pollution
Most offices are still open, leaving no option for employees to evade the alarming air pollution. In such a scenario, it will be wise for a person to use special air-pollution masks if at all they need to venture out of their houses.
These masks are not only an effective agent against air-pollution also provide protection against a few air-borne diseases. These masks are slightly expesnsive than surgical masks but offer much better functionality. The masks are required to be replaced after a few days of usage.
The masks are available in N9and N9variants which are degrees of filtration. These respirators are designed to offer maximum protection without hampering the breathing pace. The disposable respirators offer around 9per cent protection against air-pollution.
These respirators are made for long term usage and are much more expensive than the disposable ones. The respirators come with a sheet of activated carbon and a replaceable filter that are to be replaced in every 3-days of general use.
First of all thanks for reading my article to the end! I hope you find my reviews listed here useful and that it allows you to make a proper comparison of what is best to fit your needs and budget. Don’t be afraid to try more than one product if your first pick doesn’t do the trick.
Most important, have fun and choose your Disposable Filters wisely! Good luck!
