When you are considering buying an air purifier, there are several different features that you need to look for.  These features include, its ability to keep the air clean, how many and what type of particles it removes from the air and finally, whether or not it is designed to help people with allergies.

Air purifiers such as the Ionic Breeze are often touted as being able to do all the work of a normal air purifier and more.  However, the Ionic Breeze has nothing on the IQAir HealthPro Plus.  The IQAir HealthPro Plus is the most advance air purifier on the market.  It has four different filters that catch over 90% of the nasty particulates that can cause allergies.  This model is also great for people who are suffering from Asthma, as it catches the molecular irritants that bother so many asthmatics. 

The Austin Air Allergy Machine is another great choice for anyone who is trying to eliminate potential allergens in the air.  The Austin Air Allergy Machine can be used to filter nearly all the potentially harmful allergens and other problems out of the air in your bedroom.  While it does cost a small amount more than some other machines, the Austin Air machine does have a few unique benefits.  The first of which is its four step system.  This system ensures that any possible allergens, viruses, bacterias or other problems in the air are caught and prevented from exiting the machine.  The Austin Air Allergy Machine uses a large particle filter, a medium particle filter, activated military carbon cloth and then finally over thirty feet of HEPA filter.  With this unique combination, you can be sure that you will sleep without any problems.  However, in the exceedingly rare case that you do have a problem, Austin Air has a 30 day no questions asked, money back guarantee. 

Sometimes other options will just not work for other people, this is when I recommend Alen A350.  The Alen A350 is the super workhorse of a air purifier.  It costs more than any other machine that you will find, but the additional price is well worth it!  Other machines will say that they are able to remove 90% of pathogens, but many are just built with too low of quality materials in order to achieve this.  The Alen A350 is not one of those machines at all.  Only the best quality is put into it, and you get the best results.  Alen has had test studies conducted, and their machines remove 97.5% of pathogens.  You will be hard pressed to find a machine that will be able to remove more!  Alen also has a 30 day no questions asked money back guarantee.  However, after you use an Alen A350, you will not want to go back to any ordinary air purifier.
