Rhino Pro Pre-Filter

It is designed to trap dust and other airborne particles, so they don’t clog the filter’s carbon bed. The polyester wool extends the Rhino Pro Filter’s 2-year lifespan by capturing impurities while allowing air to flow through to the carbon bed. The pre-filter slides over the top of the filter.

The pre-filter is machine washable but should be replaced every 3-6 months for continuous high-quality air filtration.
