If breathing is difficult even in a home a portable air cleaner may help. These devices filter the contents of the home. They are not all created equal however. Some merely offer a mechanical filter that traps a few particles, while others are designed to eliminate odors or gases from the air. Before shopping it is important to decide the features that are wanted or needed.
Begin by determining the seriousness of the problem that needs to be solved. The more serious the problem, the greater the need is for a better quality unit to remove the allergens for allergies. Individuals who suffer chemical sensitivities or asthma may need a different machine than those who suffer allergies. Chemical allergies can be set off by a number of different compounds so some individuals have found the glue used in the HEPA filter causes a reaction.
The volume of the room being treated is also a significant factor. In order to keep the room clean, the atmosphere must be exchanged several times each hour. The greatest of filters will not be effective in a large room if it is sized too small. The very minimum requirement is that a device offer two full air exchanges each hour.
The location the device will be used is also important in determining the best choice. In bedrooms where noise can be a factor, a smaller unit that exchanges a minimum amount of air may be desirable. In family rooms where traffic is higher, the device should have a higher exchange rate.
When faced with the decision of a unit that is rated at the minimal exchange rate or one with a larger rate, the later is to be favored. With a unit that pushes the limits, the unit must be operated at top speed most of the time for effectiveness. With a larger device, effective cleaning can occur at a low or medium speed. Operating at the lower speed will help to decrease the noise output.
Some purifiers offer an IR detector to monitor the particulates in the room. These devices automatically run on high speed when turned on, but as the particles decrease through filtration, the device moves to a lower speed. Unfortunately, many users find the area being measured is too small for the device to make the determination.
The two critical measurements of a unit's effectiveness are the number of exchanges made per hour and the percentage of pollution removed with each exchange. The second factor is the device's efficiency. With the higher the efficiency machine, fewer particles are released back into the room. A HEPA filter is rated to remove 99.97% of particulates 0.3 microns or larger. However, once the filter is installed in a device, there are many other factors that come into play. Many devices using HEPA filters allow as much as 50% of the particles to flow around the filter without passing through, giving a poor performance.
If breathing in one's home is a problem a portable air cleaner may help. These devices remove particulate matter and other pollutants. Choosing the right device can improve the home's atmosphere.
