Most air filters on the market are a compromise. Many high-performance filters deliver better airflow, but sacrifice filtering ability and engine protection in the process. OEM filters, which are usually made of paper, filter adequately but at the expense of airflow. And airflow decreases as these air filters become dirty. Not so the K&N air filter. K&N air filters increase airflow without decreasing filtration ability, and the increased airflow remains consistent throughout the filter's service interval. The secret is in the K&N filter's construction.

K&N's initial goal was to develop a filter that would deliver increased airflow during dirty, dusty off-road racing conditions. Increased airflow improves the efficiency of the combustion process, increasing horsepower and torque. But just increasing airflow without ensuring adequate filtration under those conditions would result in a ruined engine. K&N's solution was a filter design consisting of 4 to 6 layers of cotton gauze sandwiched between two aluminum wire screens. The cotton is then treated with a specially formulated grade of oil that causes tackiness throughout the cotton’s microscopic strands. The resulting K&N filter not only delivers increased airflow while trapping dirt particles that could harm your engine, that level of airflow is maintained even as the filter gets dirty. The layers of oiled cotton fibers in the K&N filter trap dirt particles that are smaller than the holes in the filter media. The thickness of the layers also allows the K&N filter to trap dirt and dust on many levels, trapping more dirt without decreasing airflow. Contrast this with a paper filter that only traps dirt on its surface; as the surface area becomes clogged, the airflow rate goes down.

Each K&N air filter is custom designed to fit into your existing factory air box. The K&N filter is economical because it's the last air filter you'll have to buy for your car. It can be washed and reused many times, and since you can usually drive up to 50,000 miles between servicing, you won't have to clean it very often. And every K&N filter is backed by K&N's Million Mile Limited Warranty. By the way, check the CARiD reviews and read what the customers think of K&N porducts.

Halo patches
I tried the Halo Dot Ultra Thin Pimple Patches, and overall I’m really impressed with them. In terms of effectiveness, they work well at helping bring pimples to a head and protecting spots overnight so they don’t get worse or irritated. The value for money is good since you get a decent amount in the pack and they’re thin enough to use during the day or night without being too noticeable. They’re super easy to use—just clean skin, place the patch, and go—and I like that they stay in place pretty well. I also find them pretty versatile, since you can wear them at home or out and about if you get a discreet one. For skin sensitivity, they’ve been gentle on my skin with no irritation, which is a big plus for me. Overall, they’re a simple, effective skincare staple I’d definitely keep on hand.

Nice patches -- Fair price -- has sulfur!
This is a review for the Halo Dot™ Pimple Patches for Face, Hydrocolloid Acne Patches with OptiMSM®, Visibly Shrinks Zit & Whitehead- Comes with Travel Essentials Inner Pouch (33 PATCHES) ($12.59) PROS: Price -- a fair deal for 33 patches and consistent with pricing of most other similar patches online. The inclusion of sulfur (this OptiMSM business) makes these unique also -- I can't seem to find others on Amazon with similar formulation, so these are intriguing. Sulfur is known for antimicrobial properties and can be helpful for zits and a little bit gentler on your skin than benzoyl peroxide or salicylic acid -- but anytime I put any sulfur stuff on zits that are above or around my eyes, it seems to migrate INTO my eyeball while I'm asleep and man is that uncomfortable. This little patch solves that dilemma nicely by keeping the sulfur put. CONS: none that I can see; these are a nice entry into the hydrocolloid acne patch space.

Disappointing results and poor adhesion.
I love Hydrocolloid pimple patches. I have used at least half of the brands available for sale and even the non brand ones. I’ve also used the hydrocolloid sheets and cut them to size and the hydrocolloid gel bandaids and used for pimple patches. I love how they help along the healing and keep me from picking at the pimple. This brand I wasn’t impressed by. None of them stayed on my face for half the night. The one that remained in place the longest out of the 4, didn’t show any signs of improvement. The longest they kept in place was 3 hours. I had to reapply and I still handbrake noticed any signs of healing after using one full sheet on 4 smaller sized blemishes because the adhesive wasn’t working.

Stops Me From Picking and Actually Works
As a woman in my 40s, I never would have guessed I’d still need pimple patches, yet the occasional zit still pops up — and these things are like magic. They work really well, blend into my fair/light skin nicely, and are barely noticeable at a quick glance. I’m also a terrible picker, and picking is so bad for your skin, so I love that these keep me from messing with pimples while doing all the work for me overnight. I’m always grossly fascinated by how much gunk they pull out by morning. Very happy to have these in my little skincare emergency arsenal.

Camouflages well with the skin and sticks long enough
I was excited to try these Halo Dot patches because I was having some breakouts before a wedding I had to attend. I put these on three nights before the wedding only at nights and left them on until the morning. I washed my face the 1st night, yet the second night I did not and it still attached (mind that I have a very oily face by the end of the day). With every application I saw good results as the breakouts were being reduced with each use. It is easy to put on and to carry out if you need to travel because it comes in two separate little envelope like package that you can put in a backpack/purse. These are thin and are almost not visible.
