How do I Choose the Best Home Air Filtration System?

The key factor in choosing the best home air filtration system is to consider what pollutants or allergens are the most bothersome. If there is no specific allergen you are trying to remove and only want cleaner air throughout your home, you may choose a lower grade system than someone with asthma or another chronic lung disorder. It is a good idea to check your home for mold, dust and other possible air contaminants to see where you are most at risk.

For anyone with a severe or ongoing lung disorder or allergies, choosing a high grade home air filtration system built into the HVAC system may be the smartest choice. This type of system filters the air throughout an entire house at once, with a central filter connected to the unit or in the return air vent. Some even have built-in humidifiers to catch dust and other airborne particles while keeping humidity levels constant. If you choose this type of system, be sure to clean the filters and humidifier regularly to prevent mold growth.

Portable home air filtration systems are the most widely sold variety, as they are generally more affordable and equally as effective as larger models. This type of home filtration system is generally of equal or better quality than a built in unit, however it cannot filter air throughout an entire home. You may need more than one unit, such as one for each room, or you may have to move the system from one place to another as you move about your home.

Another popular type of home air filtration system is the ion filter. These filters emit negative ions into the air, which neutralize pollutants and allergens. Ion filtration devices may be more costly than traditional filter varieties, although they are generally more effective at destroying microorganisms that other types of filters may leave behind.

For most consumers,cost is the major factor in choosing any home air filtration system. Although more expensive does not necessarily mean better quality, the least expensive filters are generally not powerful enough to fully clean the air in a home. This may be an issue for those who have health problems and need a more effective unit. On the other hand, spending thousands of US Dollars on the priciest devices on the market may not be the answer either. The best things to do are carefully read all product labels and manufacturers’ descriptions, and purchase the most cost-efficient system that meets your individual needs.
