Air Cleaner Technologies: Which is Right for You?

by Justin Mann

Nowadays, air cleaners are a must, especially if you have allergies or small children in the home. These devices are highly useful for removing numerous impurities from the air. But with the various technologies available in a home air purifier, it can be difficult to determine which one you need. Each kind is effective in its own way, but their efficiency varies. Following is a look at some of the different kinds of products available, as well as the benefits and disadvantages that you can get from each.

* Cloth type filter air cleaners separate dust particles, but cannot trap smaller sized particles.

* HEPA, which stands for High Efficiency Particulate Arresting, filters are able to remove almost 100 percent of particles from the air that are a minimum of 0.3 micros in size. They use replaceable filters, which means you'll be spending money on an ongoing basis.

* Carbon models trap odors and particles in a carbon filter as air passes through. These can actually trap particles smaller than 0.3 micros, but are also more expensive than the HEPA filters.

* Ozone units release ozone into the air. It's very good at removing bacteria, odors and fumes from the air. However, elimination of particles and other allergens are not part of the capability of this type of filter.

* If you want to remove mold and bacteria from the air, take a look at the ultraviolet germicidal irradiation models. However, heat extension is needed to be sure that they will be killed as they are highly resistant to heat. This is one of the most expensive models as it has the ability to trap mold and bacteria. Also, the maintenance costs are higher.

Your purchasing decision needs to take into account more than the technology; you also need to consider the requirements of your situation. For places where odor is easily trapped like the kitchen and bathroom, ozone or ultraviolet germicidal irradiation are both good options. For a place that is prone to mold, like the bathroom and sometimes the closet, ultraviolet germicidal irradiation is also great.

But the needs can change for various regions of the home. To address this, it is best to adhere to the highest level of need. As well, you don't want to rely completely on air cleaners. It is still important to make sure that the air is clean to start with. Always let air circulate, unless the outside air is highly polluted, by opening windows on every side of the house.

And ensure that your walls have a moisture repellant surface to discourage the growth of mold. Rooms like the kitchen and bathroom need to have their walls cleaned frequently because of the higher moisture levels. Keep them dry as much as possible. Another means of discouraging the growth of bacteria is to make sure your mats and rugs remain dry.
