Breathe‑easy replacement for your XJ‑2
MERV-17 HEPA (99.97% DOP efficient at 0.3 microns)
-
OEM MERV‑17 HEPA filter rated 99.97% efficient at 0.3 µm—keeps isolation spaces protected.
-
Made for the XJ‑2 negative‑pressure HEPA system—part #41142 in the official parts list.
-
Change on schedule: use the unit’s Minihelic® pressure gauge and follow CDC’s 6‑month HEPA guidance.
Best for: hospitals, clinics, pharmacies, long‑term care, labs—anywhere the XJ‑2 is maintaining monitored negative pressure.
Dirty air passes through the prefilter. The prefilter removes large particulate. The primary filter then captures the remaining particulate. As the contaminant load on the filters increases, the filters become more efficient in capturing the smaller particles. At the same time, however, the dirty filter allows less air to pass through resulting in less particle collection and a decrease in the overall effectiveness of the air cleaner.
The XJ-2 air cleaner is equipped with a pressure gauge which indicates the restriction to airflow caused by the filters loading with particulate. When the air filter gauge reaches the red arrow or a noticeable reduction in airflow occurs, it is time to clean or replace the prefilter and possibly the primary filter. The CDC guidelines specify that the HEPA filter shall be replaced every six months.
In the Box & Installation
-
Included: (1) OEM HEPA filter 41142.
-
Install (summary): Power OFF → open service door → remove prefilter 41144 → slide out used HEPA → insert new 41142 (ensure proper seating/seal) → reinstall prefilter → power ON → verify Minihelic® gauge resets near zero and note baseline. (Follow the Owner’s Manual for model‑specific steps and safety.)
FAQs
How often should I replace the 41142?
Use the pressure gauge and your infection‑control policy. The manual cites CDC guidance to replace HEPA every six months in isolation applications.
Does this include the prefilter?
No. Order XJ‑2 Prefilter 41144 separately; it captures larger dust to protect the HEPA and can extend service life.
Is this the same HEPA used when the XJ‑2 is tested as a whole?
Yes, 41142 is the HEPA element specified for the platform; AQE documentation highlights whole‑unit HEPA performance for the XJ‑2.
Any special certifications for the filter itself?
HEPA efficiency is stated as 99.97% @ 0.3 µm. CARB and ETL listings apply to the XJ‑2 unit; the filter is a consumable component.
