Captures harmful gases such as ammonia and other volatile organic compounds. Deodorizes the air, reducing odors with activated carbon and zeolite. Reduces odors more effectively than standard carbon filters and traps larger particles such as dust, lint, fibers and pet fur. Replace every 3 months.
The Kaz website claims this pre-filter can be used for the HEPA 050 air tower. That's technically true, but it's not the best fit. You have to cut the pre-filter in half to get it to the right height. It's not a huge problem, but it does cause a bit of a mess when cutting. If you have the 050 or similarly sized units, I'd recommend getting pre-filters specifically designed for those units.
