The Best Fan Filter Unit in the Industry Just Got Even Better!

Many people love our Criti-Clean Fan Filter Unit because of its industry-leading features and quality construction. But we know that easy day-to-day maintenance also means a lot to our customers. That’s why we’ve redesigned our popular Criti-Clean FFU to offer room-side access to not only its HEPA or ULPA filter, but also to the unit’s pre-filter as well.

The pre-filter in any FFU keeps debris and contaminants from entering the unit from the plenum side. But the pre-filters on the other FFUs on the market today are not accessible from the room side, which makes them extremely difficult and time-consuming to change – if they ever get changed at all.


So the AJ Manufacturing Criti-Clean FFU is the only option available that gives you all the convenience of room-side access to both the pre-filter and the HEPA or ULPA filters. That means we make it easier to keep your unit clean and running at peak performance. And remember, you’ll also get these outstanding features which make Criti-Clean the most popular FFU on the market…

  • Stainless steel construction with an all-welded plenum
  • Higher CFM output than our competitors’ models
  • Computer-controlled, variable-speed ECM motor
  • HEPA or ULPA filter with gel-seal frame
