Please Note:
Our Pre-Filters have the ability to collect many times more particles than typical pre-filters.
Therefore they may require more frequent changes than a typical pre-filter would. This brings us to the point of this type of pre-filter. Not only does our pre-filter contribute to cleaner air, it also adds to the useful life of the main purification filter. In turn, this saves you money from having to buy the more expensive purification filter replacements as often!
Factors to Consider in Changing Frequency:
Number of people and pets
Smokers
Number of Vacuums
Amount of Contributing Odors
Time of the year (pollen and mold spores)
VOC in the air ( a major health concern in homes today)
Hours of Operation (24/7)
