In one sentence, describe what the following article is about: Turn on a hose or tap to a light stream. Hold the air filter directly under the stream so that the water runs through the inside of the filter to the outside. The water will carry away the dust and dirt loosened by the cleaning solution. Rinsing from the outside in will just force dirt further into the filter. If your air filter happens to be especially filthy, you may need to repeat the cleaning and rinsing process more than once in order to restore it to a like-new condition. Alternatively, you can rest the filter against another object at an angle and let it drip-dry. Get off as much standing moisture as you can. Again, try not to handle the filter too roughly. Set the filter on a clean, dry towel to absorb more water. For quicker drying, make sure you leave the filter in a well-ventilated area at a mild temperature. It will usually take somewhere between six and eight hours for the filter to dry completely indoors. Plan on servicing your air filter at a time that you know you won't need to drive anywhere. Do not attempt to apply oil while the filter is still wet. If need be, you can temporarily install a regular disposable air filter so that you'll be able to use your vehicle while your K&N filter finishes drying.
Summary: Rinse the filter from the inside out with cool water. Shake off the excess water. Let the filter air dry overnight.

In one sentence, describe what the following article is about: Check daily during a severe whitefly infestation, and pluck off badly infested leaves. These have many white eggs and/or wingless nymphs ("crawlers") on the underside of the leaf. If severely infested, the leaf may be coated with a sticky or waxy substance produced by the feeding nymphs, or it may turn yellow and spotted. This method works best for small gardens where you can check each plant regularly. You can dislodge young whiteflies from the underside of leaves by spraying them with a hose. To catch the winged adults as well, use a hand-held vacuum cleaner to catch whiteflies when they are most sluggish, in the early morning or during cool weather. Put the vacuum cleaner bag inside an airtight plastic bag after capturing, and freeze it for 24 hours to kill the whiteflies before emptying in the trash. This method is most helpful when the whiteflies are first noticed. If they have had a chance to lay eggs, these may remain on the leaf and start a new generation of many hundreds or thousands of whiteflies after hatching. If the infestation is minor, this method can help reduce the population of whiteflies to the point where natural predators will be able to keep the population in check. Add a layer of aluminum foil or reflective plastic mulch covering the ground. This can make it more difficult for adult whiteflies to locate host plants, reducing the amount of eggs successfully laid. This step will require special water considerations. Plants surrounded by plastic mulch will need to have a drip irrigation system. Do not use mulch in hot weather, as it may overheat the plants. If a plant is severely infested, transfer it to a separate room or an outdoor area distant from other plants. Isolate all newly acquired plants for several days before introducing them to a location with other plants, and inspect the undersides of the leaves for whiteflies. As explained in the section on natural enemies, insecticide rarely works on whitefly populations, and may even kill the animals that feed on them. However, if the whitefly population in your garden is out of control, you may have nothing to lose. Neem oil, insecticidal soap, and malathion are common options, and you may wish to choose two of them to alternate between, in case your whiteflies are resistant to one. Apply an insecticide once every five to seven days to the undersides of infested leaves. Always check to make sure the insecticide you plan to use will not harm the plant you are applying it to.
Summary: Remove badly infested leaves by hand. Spray or vacuum whiteflies off the leaves. Add a reflective mulch. Isolate new or infected plants. Use insecticide as a last resort.

In one sentence, describe what the following article is about: Cellphones have never been so fragile and prone to scratching as they are today. Screen protectors are commonplace, and you should invest in one if you're the slightest bit worried about damaging your phone. Common phone protectors aren't generally too expensive, and they'll be much more affordable than replacing your screen or phone if the damage is bad enough. Higher-end protectors are virtually unbreakable, while affordable brands will at least take damage so your phone proper won't have to. Between a plastic screen protector and tempered glass protector, you are better off investing in the latter. Tempered glass protectors offer better durability, visibility, and comfortable feel. Most of the time your phone is scratched or damaged, you'll be on the go somewhere. It's important to consider where scratches come from and how they're most likely to be made. Put your phone in a separate pocket than your keys or coins. If possible, place your phone in a zip-up pocket to prevent it falling out accidentally. Don't put your phone in your back pocket. On top of risking cracking if you sit down on it, there have been reports of it causing nerve problems due to the pressure it creates on your backside.
Summary:
Purchase a screen protector. Stow your phone somewhere safe.
