The problem of dry air is common both in cold climate and warm climate. Ultrasonic humidifier effectively helps to solve this problem by creating the right level of humidity. Using Ultrasonic humidifier is very convenient and safe because it has no sound and the water in this device is not heated. Therefore, this device can be used even in rooms that the children use. It helps to maintain the right level of humidity in both houses and in big offices.
It works on the principle of using ultrasonic sound waves to propagate water droplets from a water reservoir which is in-built in this device. It helps to humidify a place without using heat and therefore a large amount of money can be saved on electricity.
Another advantage of using them is that they help us breathe clean air since it has the capacity of providing instant misting during humidification. There are basically available of two types in the market they are portable humidifiers and the compatible model.
The portable humidifiers are very convenient as they can be carried along while travelling and they help to humidify small areas like for example, a single room. Their maintenance is also very easy because it can be cleaned very easily. Most of the humidifiers come fitted with a humidistat therefore; they can be adjusted and set to the desired levels if the humidity level increases or decreases.
HVAC-compatible humidifiers are used in large offices or for humidifying the entire house. They draw the power from the main power supply as they need high voltage. The maintenance should also be done frequently with solvents to air contamination.
There are many advantages of using ultrasonic humidifiers from the conventional models. One of the main advantages is that these humidifiers do not release out a white dust that is common in the conventional models.This is possible because these devices are fitted with a metal platform which effectively traps the dust inside and prevents them from escaping outside.

1. Mac Keyboard Gets Liquid Exposure
Immediately disconnect the power cord and remove the battery from your Mac. Turn your Mac upside down at an angle to allow the moisture to drain out. Do not lay the machine flat because we want to separate the machine from the moisture. Be sure to have a towel or cloth underneath the Mac to collect the dry liquid. Be sure to allow at least 3 days to pass before you reinstall the battery and power up the Mac. This will allow the moisture to dry completely.
DO NOT USE A HAIRDRYER! Hairdryers can burn the liquid onto important Mac components which can cause a application or software malfunction. If you are desperate and money isn't a concern, you can contact a data recovery company such as Techserve or DriveSavers after you pull the plug from your Mac. Another option is to take your Mac in to an Apple Store but remember food and liquid damage is not covered by Apple Care.
If you computer starts up, and you are a self sufficient type of guy, you may be able to do the next step by yourself. You will have to disassemble your Mac and swab down the affected area with distilled water or denature alcohol which is available at hardware stores. If you aren't confident in dissembling your Mac, take it to a local Apple Store for cleaning. Be sure to clean the affected area because if left, the liquid may corrode the Mac's inwards overtime.
2. Mac Stuck in StartUp Mode
What do you do when your Mac stays stuck on the start up screen? First step is to reboot the Mac and hold down the Command and S key as the Mac is starting up. This will allow you to boot in single user mode and you will see white text appear on your screen. Once you see the # command prompt, type /sbin/fsck/-fy and hit return. The Mac will go into file system consistency check.
Be patient this process may take anywhere from 15 minutes to an hour depending on the problem that is plaguing the Mac. Don't be alarmed when you see the message "File System was modified". Repeat the command prompt step again and again until you see a message stating "no problems were found". Once this message appears, type in reboot.
If this doesn't work and your computer is still stuck in start up mode, insert your OS X install disc into the disc drive and reboot. As the Mac is starting up, hold down the C key. If you are running 10.4 or later go to ApplicationsUtilitiesDisk Utility, select your hard drive and click Repair Disk on the First Aid tab. If there aren't any disk errors, click Repair Disk Permissions. When this process is complete, restart your Mac.
If you are running OS 10.2 you can do the same steps except you will go to the InstallerOpen Disk Utility. If all the above fails, you will probably need to take your Mac to the Apple Store for professional repairing.
3. Mac Will Not Power On
If you attempt to power up your Mac and there is no start up chime, sound from the hard drive or Mac's fan, and the light on the power indicator isn't on, unplug you power cord and remove your battery. Also remove any other peripherals that may be connected such as printers, displays, etc. Now after waiting about 2 minutes, reconnect the battery and power cord to check if your Mac will start up normally. If it does, you are safe and can plug back in all peripherals.
If this doesn't work, unplug the power cord and disconnect the battery again. Now try to reset the System Management Controller. If the System Management Controller's file has been corrupted the Mac may not recognize it's power supply. If you have a Mac Book or Mac Book Pro, hold the power button down for 5 seconds, then reconnect the adapter and press power to hopefully start up the Mac.
If you have a Mac Book Air you will need to hold Shift-Control-Option on the left side of the keyboard and press power. If you use another model, check with Apple Support, or Google the model name of your Mac + SMC to learn how to reset the System Management Controller.
4. Mac is Running Slow
One reason your Mac may tend to run slow is because a lot of applications and toolbars we may not use may be utilizing a lot of the Mac processing memory. Its time to erase / consolidate some of those resources you do not need. Create a new folder and put all the icons and folders into the newly created folder.
We do this because desktop icons and folders also use processing memory. If you want to consolidate even more, turn off some of the features you don't need like animations, effects, and scrolling bars. The simplest way to do this is to use TinkerTool a free app that lets you customize OS X.
5. Mac Application Crashes
One cause of application failures could be because of system updates, downloading or installing a new piece of software or editing or changing the preferences on your Mac. If you have did none of the above the problem may be the application's preferences. Go to ACCOUNTS create a new account and log in as the new user. If the application works with the new user account, the problem may be with the application preferences.
If this is the case you could either reset application preferences by holding down command+option+shift keys when starting the application or you could go to Users/Library/Preferences folder and removing the crashed application's preferences. If you still can't figure out how to reset the application default preferences, you could go to the manufacturer's website.
6. Mac Makes a Mysterious Buzz Noise
If you hear a high pitched noise or weird buzz coming from your Mac's hard drive that may be a warning sign it may be time to replace it. Another sign may be frequent application freezes or start up freezes. Also if files are starting up slowly or closing slowly that is another sign it may be time to replace the hard drive. Your Mac's monitoring system may say the hard drive is o.k. but don't take any chances! Back up the drive asap!
7. Macbook Gets a Scratch
Some people have tried the DIY approach to repairing scratches. I have heard stories of people taking their MAC in to jewelers to have the scratches buffed out. Other people have used put Vaseline into the scratch to mask it. You can try Apple Care but usually they won't cover this.
One solution is TechRestore. TechRestore can replace a MacBook display anywhere from 0 to 0 depending on the display size of your MacBook's screen. If you are handy and want to do it yourself, PowerBookMedic is a good source to purchase a new display.
8. Your Mac's Fonts Are Going Exorcist
Small font files and corrupt files can cause application crashes and display issues. If you are running OS X (Tiger or Leopard) you can avoid by going into applications and launching Font Book. Once Font Book is open command click a group of fonts to check if they are corrupt and then select validate fonts. Bad files and corrupt fonts can enter your system from being downloaded from bad websites.
If a particular file is corrupt, you will see a round icon with an X on it. Click the box next to the bad font and then select Remove Checked to remove the file from your system. If there is a yellow warning sign next to the font, remove the font file from the Font folder, restart the system and hopefully this will resolve your issue.
If you are running an older OS system on your Mac I would suggest a font manager like Extensis Suitcase Fusion. This app is highly recommended and offer many ways to organize and work with your fonts.
9. SAFARI IS RUNNING SLOW ON YOUR MAC
If Safari is having performance issues try Resetting Safari (go to Safari>Reset Safari). Doing this will give you the option to delete stored login information, cache, favicons, history, and cookies. Before you delete everything try only deleting cache, favicons, and history first.
10. REMOVING SCRATCHES FROM YOUR IPOD OR IPHONE
Many people use toothpaste! Yes toothpastes can be used to remove the blemishes and scratches on your screen but I wouldn't recommend it because certain brands of toothpaste may be more abrasive and could possibly add more scratches.
One solution I would suggest is Applesauce polish. Applesauce is simple to use, just follow the self explanatory directions.
