What Does an Air Purifier Do?

An air purifier, in very simple terms, is an air cleaner. What it does is removes various contaminants from the air in the room where it is placed, thus improving the quality of your indoor air.

Air purifiers are most beneficial to those who have allergies or asthma as they remove various allergens and irritants from the air. These devices also work really well at removing cigarette/tobacco smoke from the air and reduce the effect of passive smoking.

How Does an Air Purifier Work?

Air purifiers work just like sieves, only much smaller. Just like sieves, all the bigger and unwanted particles are removed from the filtered medium. The devices use these fine-sized sieves to filter the air as it circulates through them.

Some devices use additional features to enhance their air purifying functions. These features may include an electrical attraction for the particles to trap them, or an ultraviolet light system with the capability of killing a number of microorganisms. Such a light system not only keeps the air purified but also saves the filter itself from being contaminated by unwanted germs.

How to Choose a Quality Air Purifier?

As mentioned earlier, choosing the right air purifier yourself can turn into a hefty task if you’re not sure what to look for. Like every product, air purifiers have some key features that need to be considered before buying one.

Type of Filtration

Air purifiers use different types of filtration. The most common ones are HEPA and Carbon Filtration. Both filters are used for different types of air purification. HEPA is the right choice if you just want generally cleaner air, while a carbon filter is more efficient at removing allergens from the air.

Area of the Room

Different air purifiers work efficiently in different sizes of rooms. You need to evaluate the size of the room where you wish to use an air purifier and choose one that is best suited for that size.


Keep your budget in your mind while you look at all your options. The price of an air purifier may greatly vary from roughly $20 up to $1000. Still, you do not necessarily have to spend a fortune for a good air purifier. Provided you look at the right features, a good quality air purifier can be fit into any budget.
