The KwiKool 18-FILTERPRE is the OEM pre-filter for the KBP1800 and KBX1800 BioAir 1800 CFM air scrubbers. Like the 14-FILTERPRE for the smaller models, it captures large particles upstream of the main HEPA filter to extend its service life. The 18-FILTERPRE is sized for the larger filter frame on the 1800 CFM models and is not interchangeable with the 14-FILTERPRE used on the 600 and 1000 CFM units.
