Air Cleaners

We can furnish and install Media Air Cleaning units which will remove dust and dirt particles from your home up to 65% of 1 micron. 1 micron is equivalent to 1/25,400 of an inch. To put it into perspective, a human hair is equal to 100 microns. Media air cleaning units have several advantages: there is no electric used and therefore no cost to operate, the media filters are easy to replace and as dirt collects on the media, the collection surface area actually increases which increases the unit’s efficiency. Naturally this is only true for a period of time and the media should be changed twice a year in most homes. This period will vary with the individual home.

For more information on how a Media Air Cleaning unit can improve the air quality in your home, contact us at 314-872-8070 or send us a message.
