- Pleated Filters
Today's trend is to use a minimum of 20% air filtration. Pleated panel filters meet this requirement, as well as, reduces operating cost in terms of energy consumption and overall filter replacement costs. Pleated filters come in two models - Standard Capacity (10 pleats per foot on 2" deep) and High Capacity (15 pleats per foot on 2" deep). Pleated filters offer cleaner air, longer service life, reduced yearly installation cost, reduced equipment maintenance, reduced energy cost, and reduced interior decorating expenses over other less efficient panel filters. Our pleated filters come with a blended media that obtains ASHRAE efficiencies of 25-30%.

- Replaceable Pleated Elements
Pleated elements can be used in pad holding frames. Pleats save material costs, storage space, labor and disposal costs because they are compressed to take up little space and are easy to transport. Pleated elements are available in pre-cut sizes or bulk rolls in 1", 2" & 4" thickness. Since they are made of the same material used in pleated filters, they provide for higher efficiency than some disposable filters.

- Gas Phase Filters For Gas And Odors
These series of filters offer cost effective solutions to poor indoor air quality which is associated with over 40% of today's buildings. They will replace existing HVAC filters and require no equipment retrofit. They save in freight since they are lighter than bulk compound filters. Costly energy is saved because pressure drops are extremely lower than bulk filters. They serve a dual function by removing both gaseous compounds and particulate matter from the filtered air. The gaseous control compounds are impregnated onto a polyester filter substrate and offer highly effective removal of gaseous contaminants as well as solid airborne contaminants. Filters are offered in the following medias: activated carbon and zeo-lite. Filters are offered in thickness' of 1" to 12" and are offered in many face sizes.

- Bag Filters
Medium and high efficiency bag filters come in a wide range of sizes that fit all types of air filtration systems. The controlled stitched pocket design enables high dust holding and long life. The self supporting bag filter provides superior performance in four efficiencies: 40-45%, 60-65%, 80-85%, and 90-95% constructed from medium and high efficiency synthetic or 90-95% glass media in a choice of face sizes, number of pockets, and pocket lengths.

- Rigid Cell Filters
Rigid cells are ideal for variable air volume systems, because its performance is not affected by changing air velocity or system shut down. It is also ideal for equipment where space is a problem. Filters are offered in medium and high efficiencies in glass and synthetic media. Our rigid cell filters are encased in metal framing in 6" and 12" depths. Peripheral headers are available for side access units.

- Mini-Pleated Filters
This state of the art filter allows for high efficiencies, lower pressure drop, extended life, and can occupy less depth space than other high efficiency filters. These are positively the best type filters to use to upgrade your filtration. They are produced 60-65%, 80-85%, 90-95%, and HEPA grade filters in 2", 4", 6", and 12" depths. Excellent filter to retrofit existing equipment to higher efficiencies. Filters come in many different frame types.

- Extended Surface ASHRAE Cell Filters
Compact design with rigid construction that fits all HVAC systems. This type filter is well suited for variable air volume systems where there is changing air velocity, in units where there is turbulent air, high temperature or high humidity. Available in 60-65%, 80-85% and 90-95% efficiencies. Their 6" and 12" depths enable them to be installed where space is limited. Available with side access headers and frame constructions of particle board or metal cell. No header, metal cell shown above.

- H.E.P.A.
Used where the highest degree of filtration is desired. H.E.P.A. filters are available in DOP efficiencies of 95-99.97% and scanned units of 99.999%. As in the above ASHRAE cell filter, H.E.P.A. filters offer different framing constructions and CFM capacities to suit your specific use. Custom shapes and sizes available for O.E.M. applications.

- Ring Panel Filters
Self-sealing design guards against air bypass, because the filter edges act as gaskets. Ring panel filters are fast to install and are fully self-supporting. Units are available in many thickness or ply's and media types with internal wire rod supports. "Slip on" types are available which enable you to change out media by slipping replacement media over existing wire support rods.

- NESHAP/CRS 319 Paint Overspray
The "CRS 319" system is specifically designed to help aircraft manufacturers and rework facilities comply with the tightening EPA emissions standards such as "Final Air Toxics Rule," "NESHAP," Proposed Standard Test Method 319, and "Federal Code of Regulations Title 40 Part 63 Subpart GG Section 63.745." Two or three stage systems available, each with multiple options to tailor fit each application. Test reports available.

- Washable Expanded Aluminum Filter
The most poplar washable type filter on the market is this expanded aluminum mesh filter. It is used as an HVAC air filter as well as a grease filter in residential range hoods. This filter is produced by building up various layers of expanded aluminum materials bonded together to form the filter pad. These bonded layers form a baffle effect to trap airborne contaminates. Filter is available in standard and non-standard sizes, and in thickness' of 1/8", 3/8", 1/2", 1" and 2".

- Heavy-Duty Washable Air or Grease Filter
This heavy-duty filter utilizes corrugated galvanized steel filter cloth and corrugated galvanized expanded steel. This versatile filter can be used in air, grease or oil mist applications. It is available in standard and non-standard sizes, and in thickness'of 1" and 2".

- Permanent Pad Holding Frame & Replaceable Filter Pad
Pad holding frames enable you to have a permanent filter frame with disposable filter material. Why throw away the frame each time when the only part of the filter that needs to be disposed of is the filter material. The most commonly used filter materials are fiberglass, polyester or pleated elements.

- Filter Material For Permanent Pad Holding Frames
Bulk filter material is offered in polyester rolls and pads. Rolls come in various widths so as to eliminate any waste when cutting pads. PureAir can also provide you with pre-cut pads in whatever dimensions you require.
