What exactly does an air purifier do and how much does it help?
Will it reduce the frequency that I need to dust in the room? Will it make me more or less suseptible to colds (more because I won’t build up immunities)?
How often do I need to replace the filters?
If there are different kinds, which kind is best?
If you use an air purifier, you will not need to dust very often. There are electrostatic air purifiers, ionic air purifiers, and an air purifier that uses an HEPA filter. With the HEPA filter one, you will need to put in a new filter every three months or more often. The other two kinds do not have a replaceable filter. With the electrostatic air purifier, you just take it apart and wash the filter, dry it, put it back together, and it is ready to go again. So the electrostatic air purifier is cheaper to operate, since you do not have to purchase filters. However, I have an Oreck 2000 air purifier, which is electrostatic. It does seem to remove pollen, but it did not help my mold spore allergies at all. I think one with a HEPA filter would be more effective. We do not have one because a filter can cost as much as $80.
