Renowned for their ease of installation and operation, the MAC 10 line of FFUs offer low energy consumption, low sound levels, and a low profile. Note: The LE models offer low watts, low profile, and low operating costs.&lt;/p&gt;&lt;p&gt;The Envirco replacement filters are Dimple Pleat®, a completely natural media pack that uses no glue or ribbons, available in a 3”depth. The filter construction will consist of a microglass fiber with an acrylic latex binder. Choice of HEPA (99.99% efficiency on .3 μm particle size) or ULPA (99.9995% efficiency on 0.12 μm particle size) DIMPLE-PLEAT® filters. All replacement filters are (UL-900), manufactured and tested to the latest IEST RP Standards. Please consult the factory for the correct sizing and filter configuration.&lt;/p&gt;&lt;br /&gt;&lt;br /&gt;Visit &lt;a href="https://products.yourcleanroomsupplier.com/pre-filters-c72all.aspx"&gt;Pre-Filters&lt;/a&gt; to see additional products in this category.&lt;/div&gt;</description>
