The Purafilter is a combination chemical and particulate filter designed to replace existing particulate filters in retrofit or rework applications. Purafil engineers are the first to successfully suspend sodium permanganate adsorbents in a bi-component fiber matrix.
Chemical filtration systems utilizing sodium permanganate remove a broader range of contaminants than carbon-only filters and exhibit higher efficiencies. Because of the Purafilter’s broad-spectrum removal capabilities, it is the only chemical filter capable of meeting the stringent requirements of ASHRAE 62’s Indoor Air Quality Procedure.Read More
The bi-component fiber matrix, or filter, does not require the use of adhesives, so adsorbents are fully exposed for reaction with gaseous chemical contaminants and odors.
Purafil offers two grades of the Purafilter: Purafilter-Commercial Grade for light to moderate duty applications and Purafilter-Heavy Duty for high contaminant load applications. All standard sizes are available.
Adsorbents are evenly distributed throughout the filter structure to assure the highest filtration efficiencies. The Purafilter offers a higher media loading than other chemical filters, enabling a longer service life and reduced maintenance.
Features and Benefits:
- Contains up to 10 times the media of activated carbon filters
- Removes more gaseous chemicals and odors than activated carbon
- Removes gaseous chemicals and solid particulates
- Adhesive-free filter design
- Minimized by-pass and high removal efficiency
- Purafil SP Media will not desorb
- Low pressure drop
- Long filter life
- Reduced maintenance
- Improved indoor air quality
Camfil City Pleat
Combination/ Molecular Filter
The Camfil CityPleat features a combination filter that removes particulate, gases and odors. It is recommended for use in all types of HVAC systems (both indoor and outdoor air) in a wide variety of residential and commercial applications when only a 1”, 2” or 4” space is available.
It is available in a wide range of sizes, depths and media capacities to offer relief from unpleasant odors including human bioeffluents, food preparation, waste products and more.Read More
This combination filters has a MERV 8 prefilter state to protect equipment and secondary filters and is heat bonded to Camfil’s Rapid Adsorption Dynamic (RAD) media layer. The RAD media then receives air from which dirt particles have been removed to provide a better initial removal efficiencies and longer lifetime against offensive molecular contaminants.
CityPleat filters also provide a solution for geographic areas of non-attainment as published by the United States Environmental Protection Agency (EPA) in the National Ambient Air Quality Standards (NAAQS).
The 1” deep CityPleat is available in five sizes, the 2” in seven sizes and the 4” in four sizes to fit a variety of existing HVAC equipment.
Features and Benefits
- Combination air filter for the removal of particulates (MERV 8) and odors/gases
- Camfil RAD high-preformance media technology
- Moisture resistant beverage board frame
- Individually packaged to ensure performance on installation
