We may be concerned about pollutants in the air we breathe but most of us don’t realize that the particles in our own homes can be more noxious than those outside of it. Those people who do recognize this, especially those suffering from allergies are investing in home air purifiers. These units help to rid your home of polluting irritants and debris by removing them from the air, cleaning the air and redistributing it.

Perhaps one of the most highly recommended air purifying systems is that made by IQ air. These units work on HEPA which is a fan operated system along with a series of filters – this enables them to clean up to 98% of the air within a given square footage, compared with the seventy five percent rates of other systems. The IQ system is also said to be effective against cigar and cigarette smoke and is recommended for people suffering from allergies. However, the added effectiveness of the IQ system means that it can be quite noisy. If you want a quiet system then the Blueaire may be the system for you.

The Blueaire system is a hybrid system because if uses HEPA filter technology along with electrostatic air. This is meant to ensure its effectiveness in dealing with smoke as well as airborne allergens and pollutants. This is achieved by the use of an optional extra known as the stop smoke filter. The larger pores in the filter mean that the unit has a quieter air flow. The addition of carbon filters is designed to reduce negative ions and a decrease in ozone.

HEPA activated carbon is also a feature of the popular Austin Air purifiers. The system relies on long life filters, however the five year replacement period has raised some concerns as it is argued that the filter cannot operate at optimum level if it is blocked by debris. This could end in some of the contaminants being released back into the air as some reviewers have pointed out. One reason that these units are so popular is because even larger units can be moved from one room to another as they are fitted with castors.

Air purifiers that use electronic carbon mat technology work well when it comes to removing debris but they are not good at removing smoke and smells. Trion make this type of purifier, and they are usually small, portable units, designed to fit smaller spaces. Trion filters are washable but some experts say this can affect their efficiency.
