One of the questions we are most often asked is what is the best home air purifier?  This can be a difficult question to answer as each one works best for certain allergies or asthmatic concerns.  There are also many different types of allergens and pollution in the home, such as pets, dust or other issues.

Here is a review of some of the more common and best home air purifiers that are on the market today.

Home air purifiers with the High Energy Particle Arresting (HEPA) filters are a standard in home air purification.  The HEPA air filtration systems were originally developed by the US Government to be used in their “clean rooms”.  These clean rooms were often laboratories or other areas where any dust could contaminate or ruin projects or experiments.  NASA is a great example of users of the HEPA filtration systems.

The HEPA filter is made of a paper or polymer material with microscopic holes in it that allow air to pass through.  Due to the small size of the holes to allow air to flow through them, you can recognize the HEPA air filter by its accordian design.  This creates more surface area for more air to flow through.  When used in home air purification systems, the HEPA filter should be changed every 6 months at the most, sometimes more often depending on your living conditions and environment. 

Another home air purifier that is growing in popularity is the ultraviolet light air filter.  These filters use ultraviolet light (UV) light at a specific intensity to destroy dust and micro-organisms, such as bacteria and viruses.  The major disadvantage of the UV air purifier is that very few dust particulates are removed as there is no real filter, like a HEPA filter.

Ionic air purifiers are used on submarines and in pet stores to keep down dander.  The ion air purifier uses negatively charged ions to attract the positively charged dust particles.  They work well, however there are some disadvantages to having them.  If you use an ion air purifier and it is mounted on the wall, you can notice a buildup of black soot material.  Also they are used only locally in each room as they have no fan to draw air across themselves.  You would need to have one per room for them to operate effectively.

Those are the three most popular and best home air purifiers that are on the market.  As each application is different, as is each allergy or home, you should do proper research to find the best air purifier for your home. Finding the best air purifier will help you find the allergy relief that you are looking for.
