Are you concerned about the quality of the air in your home?  Does someone in your household suffer from allergies or asthma?  You might consider buying an air purifier.  Air purifiers filter the air your family breathes, removing all containments such as allergens, dust, particles, smoke and odors.  The better your air purifier, the cleaner your air will be.

Air purifiers come in a broad range of prices.   When looking to purchase an air purifier you should consider the following before making your final decision:

The Size Of The Air Purifier (the size of your room)

The size of the air filter you buy is determined by the size of the room in which it will be used.  Large rooms require larger units than small rooms.  There are portable air purifiers, great for travel, and air purifiers that purify the entire home.  Determine which room(s) will benefit most from an air purifier and measure the dimensions of the room. 

Efficiency ratings for air purifiers are based on standard sized rooms.  The efficiency rating will tell you how often the volume of air in a room will pass through a filter.  Buy an air purifier according to the dimensions of your room so you will be sure of getting the most for your money.

The Features Offered By The Air Purifier (what features do you need?)

Today’s air purifiers come with many options.  You may be interested in all these, some of them, or none of the options.  The quietness of the air purifier may be important to you.  You might be interested in multiple settings, or you might want an air purifier with a night lite attachment.

How Well Does The Air Purifier Work (filtration performance)

Here is the biggie.  When buying an air purifier you must find out how well it performs.  Generally, the more times air passes through the filters the better.  Better air purifiers use a 3 time pass system.  The first filter will trap the largest of contaminants, each succeeding filter catching smaller and smaller particles until clean, pure air is released in to your home.  Each filtration makes the air you breathe cleaner.

You should also consider a HEPA certified filter when buying an air purifier.  HEPA certified filters can remove 98% of airborne contaminants!

Do your research, decide upon the features you want and the type of filtration system you need for the area to filtered and you will  be able to buy the best air purifier for you.  In addition to considering “the biggies” above, take a few minutes to look for availability of filters, the HEPA trademark, certifications, warranty, and efficiency ratings.
