    Air Purifiers and Monitoring Filters

    Posted by CleanAlert Blog Team on Mar 21, 2017 11:57:27 AM


    Deciding where to place air purifiers in rooms is important. We recommend for bedrooms a quieter air purifier with less air exchanges during the night, than a family or living room where there will be more traffic and faster re-polluting of the air.

    Where are you Going to Put the Air Purifier in your Room?

    Whenever possible, we'd suggest placing the air purifier in the middle of the room.

    As the particle count is reduced as the air purifier cleans, the room, the remaining particulates will spread out to maintain this equal distance. As they move across the room, they will eventually be drawn into the vacuum that is created by the air purifier’s fan. Therefore, placement of an air purifier on the sides or ends of a room will be able to filter the particles on the opposite side of the room.

    What about noise?

    Some people are able to drown out the background noise from purifiers while others cannot stand any fan noise. There are lots of options in the market which offer quiet purifiers. Many also provide that all-important smooth running machine with a consistent pitch and noise level.

    Does size matter?

    There are lots of options out there when it comes to size and capacity. If someone purchases an air purifier that is tight in its sizing capacity they will find they need to run the unit on high most of the time, and even the smaller air purifiers are noisy on the high speed. Make sure to consider the size of your rooms when makeing your buying decision
