The more research we do on air purifiers, the more we like Airpura.  Most of us know that we need to purifier our indoor air especially people who have many allergies or who have low immune systems.  There is no doubt that indoor air is worse for us and unhealthier than outdoor air.  Some studies show 9 times worse, but the number really isn't as important as knowing that it is not as safe as the outdoors:  we need to do something.  We have tons of regulations that limit the outdoor air pollution but virtually none for the indoor air. 

Some simple, easy, and cost effective things you can do to improve your indoor air quality (and reduce allergens) are shown below:

• Open your windows when possilbe to allow fresh air circulation
• Use nontoxic cleaners.  This is huge.  All the chemicals in the cleaners inevitable transmit to the air that we breathe
• Keep carpet vacuumed and dust under control.  Dust is not just unappealing but also hold grems that cause us to have breathing problems and allergies.
• New homes with new carpeting give off fumes like formaldehyde that are extremely hard on your repiratory system.  Ventilate, ventilate and ventilate. 

Since the tips listed above simply just aren't enough fro many people,  people are choosing air purifiers like true hepa air puriifers for their homes and offices.  Airpura  has a unique design that allows you to transform the same unit from a high quality true hepa air purifier  to a germ fighting machine that contains filtration fit for even the most sensitive individuals just by adding the correct filtration.  If you are interested in a germ killing machine, then you'll want to add an UV bulb to your true hepa air purifier.  The cool thing about their units is that you can have the top of the line residential fitlration and later decide you need the bacteria/virus aspect, and all you do is add the bulb.  Pretty simple and you don't have to keep investing more money into a new machine. Similarly, you can have an air purifier equiped with the proper filtration for VOCs to cover your new home. Then later years, change the fitlration to the standard true hepa fitlration simply by changing the filter type from VOCs to just particulate matter wiht general odor gas control.  Pretty neat way to allow customers to change their needs without exhausting their budgets.

Basically there are 4 popular types of filtration:

1. High Quality True Hepa Air Purifierl:  R600
   
2. Chinese Dry Wall: C600-DLX
3. VOCs:  V600
4. Germs, Viruses etc:  UV600 (my favorite)
