    Impressed

    This unit has been performing perfectly for us; reducing the cat litter dust to nearly nothing, yet with just a vac of the pre-filter, the main filter still has over 90% of it's life left.

    311iMax pre-filter

    Ordered both the prefilter and the filter! Was very easy and arrived quickly! Very easy to change out as well! A little pricey but I guess for the length of time it’s good for not too bad.

    Great Pre-Filter

    The Blue Pure pre-filter is both attractive and functional. Works very well to trap large airborne particles.
