¹ Pleated pre filters should be used in virtually all filtering applications, except where indicated below. Ace standard pleated pre filters are rated at 40% efficiency @ 5 microns, equivalent to MERV 9.

² Odor control pre filters are very low efficiency pre filters used especially for the control of weld smoke odors. 91-937 are to be used in pairs, or in conjunction with a 91-955-6 standard pleated pre filter.

³ Oil control pre filters are very low efficiency pre filters used for the control of light oil mist. The filter is washable. 91-958 is to be used in pairs, or in conjunction with a 91-955-6 standard pleated pre filter. Do not use for machining operations.

⁴ HEPA filters should be used for stainless steel welding or for processes where the highest degree of filtration is necessary. Stainless steel welding produces Hexavalent Chromium, and HEPA filtration is an important tool for the capture and containment of this substance. Avoid using HEPA filters in general welding applications, as HEPA filters tend to consume at a faster rate than less efficient filters. Ace HEPA filters are rated 99.97% @ .3 microns.

⁵ Carbon steel filters, otherwise known as 95% filters, should be used for most all welding operations except where HEPA or 65% filtration is necessary. Ace 95% filters are rated at 95% efficiency @ 5 microns, equivalent to MERV 15.

⁶ Large particle filters, otherwise known as 65% filters, should be used when welding on dirty or rusty material, where flaking would quickly clog a higher efficiency filter. Ace 65% filters are rated at 65% efficiency @ 5 microns, equivalent to MERV 11.

⁷ Cleanable filters are all purpose high efficiency filters specially designed to be cleaned after each use. These filters can only be used in Ace extractors that are designed for cleaning applications. They are not interchangeable with other Ace extractors. Do not use a cleanable filter extractor where HEPA filtration is advised. Ace cleanable filters are rated at 99% @ 5 microns, equivalent to MERV 16.
