We're glad you asked! After being introduced to air purifier technology you might wonder, "This is great, but what does my air purifier actually do?" It's a great question; understanding what air purifiers do is important for picking the right one.
To Put it Simply: Air Purifiers Clean the Air
Air purifiers clean your air by passing it through a filtering process that is targeted at removing one or more types of pollutants—dust, allergens, odors, chemicals, and so on.
Clean Air = Easier Breathing
If you suffer from allergies, asthma, COPD or another respiratory problem, filtering the air has the effect of removing a hazardous irritants from your environment.
The Bottom Line
The end result is cleaner air, easier breathing, better sleep. For many this is a very real improvement in their overall standard of living.

We wish it was true.
Think of it this way: your allergy medication helps to relieve your symptoms by working with your body. An air purifier helps to relieve those same symptoms by working to prevent your body from exposure to the triggers. It's a small but important distinction.
Overall, we think that air purifiers are pretty great, but we should add a few words of caution:

A really common follow up question that we get is "I get what these things do, but do air purifiers work?"
The answer is an unqualified and enthusiastic "Yes"!
Air purifiers work to relieve many breathing related concerns—allergies, asthma or odors, for example—by dealing with a major source of these problems and replacing your pollutant-filled air with the pure air.
Without an air purifier, your lungs are the air purifier.
In fact, a well-designed and well-built air purifier can be used to effectively trap over 99% of the pollutants in your indoor air: pollutants that would otherwise end up in your nasal passages, throat and lungs. Use of a good air purifier will have a significant impact on your indoor air quality.

This is a really, really key question if you want to experience the best possible air quality in your home or office.
First, remember how air purifiers work.
The purifier's fan circulates air around a room, pulling the air and airborne allergens towards the unit. The fan ultimately pulls the air directly through the unit where the filter captures the allergens. The resulting stream of pure air is returned into the room.
Once you understand airflow, there's only three simple things to remember: Coverage Area, Placement and 24/7 Usage.
Air purifiers have recommended coverage areas. Use them! Air purifiers are built to clean the air in a certain size room and are most effective when they are used in rooms that match their coverage area. Overkill is never a bad thing in the air purifying world, so don't hesitate to go for a higher coverage area unit if you are in doubt.
Also, keep in mind that coverage areas are affected by the speed that you operate your purifier at; the maximum coverage area requires running the unit at the highest possible speed.
We always recommend that people start with putting a unit in their bedroom. You spend a lot of time in your bedroom and clean air is a great way to improve your sleep. Some people report that the noise from the fan in their unit also lulls them to sleep, but if you need a quieter experience, we can point you to units that work well at a whisper or below.
Be smart about where you put your unit. Watch the inlet and exit vents and make sure that the unit can adequately circulate air in and out of the unit.
That's right, don't think about it, just run it! Air purifiers are most effective when they are in constant use. And if you are worried about energy consumption, see our page on Energy Star rated units.
Air is always moving and our own experience and testing has demonstrated that a room full of pure air can go back to being full of pollutants in as little as an hour! The coverage area rating for each unit is also calculated with this idea in mind, so keep it on and you'll get the best possible results!
