The truth is, many factors can disrupt the performance of your air purifier: people (obstructing air flow or as a source of odors), sources of pollutants like perfumes, candles, or large objects like heavy machinery. Don’t forget that the heat source, or your air conditioner, or your door placement and how well sealed your doors and windows are when closed, are all factors that can affect your air purifier’s performance. These factors may affect whether you want to buy an air purifier for your whole house, or one for a specific room or rooms.

Where to place your Air Purifier
You want your air purifier to have best access to most of the air in the space. The truth is that eventually the air in your space will change over, but you can run your system more efficiently by moving it as required around your room, house or office if you believe that there is trapped air in any specific part, or air that doesn’t circulate well. If circulation is an issue, a standing fan can help your air purifier do the job more efficiently. Notwithstanding that, if you put it in the space, it will ultimately do it’s job no matter where it is situated.
Ideally, for maximum efficiency, air air purifier should be placed centrally in any spaces; however, with cords running to a power source and the aesthetic of your room in mind, this is impractical for most spaces, and air purifiers tend to be hidden behind furniture out of sight. Some of the new models are designed very well, but depending on the design of a room, an air purifier can be an eyesore. It is important to keep in mind where you want to put your air purifier, the proximity to a power source, and how it will look in your space.
Room Size and Concentration of Air
An air purifier should filter the air in a room no less than several times per hour. When you turn the purifier on, the pollutants will be at their highest level. Most air purifiers do a good job of quickly reducing pollutants to 20% of their former level.
If you are concerned about a specific issue, you’ll want a larger air purifier that can turn the air over more times per hour.
Room structure can vary widely, with different kinds of doors, walls, furniture, habitation, use, origination of smells or pollutants, insulation, etc. and all will affect air flow patterns that will impact your air purity. The key is to make sure your air purifier is not blocked by anything that will make it less effective.
Some people like white noise, and some people want quiet efficiency. At the end of the day, these machines use fans, so they do make some noise. Don’t forget that an air purifier made for a large room size can be very effective in a smaller room.
One benefit of a larger capacity filter is that it can often clean the air with less noise, meaning that you set your air purifier to slower speeds that can help reduce energy use and noise.
Larger air purifiers are often the best choice. They tackle pollution more efficiently, and often make less noise in so doing. If for any reason a large air purifier doesn’t work, consider instead using several small purifiers to do the job (rather than a single small air purifier). Even if you place your air purifier well, and it is small, it can outperform a larger unit placed poorly.
