Can-Lite 6" Filter | 6" x 16" Mini | 420 CFM

I rated this product 4 of 5, not due to anything inherently wrong with the product, more-so because of the availability of pre-filters is virtually non-existent. The product worked within minutes of being in operation. I have a tiny home with a couple of catnips and valerians, the catnips I have indoors and put out in spring to bring in butterflies and lacewings. Honey Bees like it too. The problem with the catnip, especially, is that it has an odor. A very strong odor, after its cut down, which can cause guests and neighbors to think you're up to something suspicious. Other odors I've found it to remove is the smell caused by spraying Neem Oil extracts, the smell of which I find less appealing than pure neem oil (also for sale at NEHydro super cheap). I've also noticed that I have less pollens in the air, because my allergies aren't going berserk. All in all, an investment worth making if you're worried about allergens/odors.
