If you can not control the air around you to effectively prevent allergic reactions and such, like when you spend a lot of time in dusty environments at work, you may want to look at the benefits of sinus irrigation. By cleansing the sinuses you can rid the body of harmful pollutants and prevent allergic reactions.

Do have a look at our extensive collection of health related articles. We have covered the topic of air purification more than once in our resource section. Here is an excerpt of one such article about air filtering and purificaiton:

The air purifier that works on incineration basically incinerates all the microorganisms in the environment with the help of its heated capillaries. With the help of air convention, impure air is pulled into the ceramic core of the air purifier. Pollutants are then destroyed at the high temperatures found here, no matter how resistant and dangerous these pollutants are. There are also no additional expenses in the running of these air purifiers as there are no filters that have to be replaced now and then. The only cost it has is its electricity consumption, and all you have to do for its maintenance is to remove the settled waste whenever it gets dumped.
