About this product

Upgrade the performance of your Pure n Natural MARK-20 commercial air purifier with this genuine 12-inch high-efficiency filter.

The MARK-20 High Efficiency filter removes the very small particles, such as smoke (tobacco, burning wood, oil, rosin), dust mites, spores, mold spores, pollen, spray paint, ashes, cement dust, auto emissions, textile fibers, fiberglass, hairspray, insecticide dust, copier toner, and most viruses, just to name a few. The High Efficiency filter is an extremely important filter because it captures a majority of the airborne particulate. When used and maintained properly, it will dramatically improve your indoor air quality. The high-efficiency filter should be replaced every year.

The High Efficiency filter CANNOT be washed.

Replace the Mark-20 High Efficiency filter once per year.

For use in the MARK-20 Commercial Air Purifier Smoke Eater

Best for

  • Smoke lounges, cigar bars, taverns and billiard halls.
  • Restaurants, break rooms, manufacturing floors or commercial spaces with heavy particulate load.
  • Facility managers and HVAC professionals maintaining ceiling-mounted air cleaners in 10-20 ft+ ceiling environments.
  • Preventive maintenance programs focused on annual filter swaps to maximise equipment uptime and indoor air quality.
  • Users of the MARK-20 (not suitable for other models unless specified) – this filter is specifically for the MARK-20 model.

Installation tips

  1. Turn off power to the MARK-20 unit and unplug/hard-disconnect as required. Refer to unit manual for safety. 
  2. Remove the access door or grill of the air cleaner to access the filter chamber.
  3. Remove the old high-efficiency filter. Do not wash the filter or attempt to reuse it — the manufacturer states it cannot be washed.
  4. Insert the new replacement filter in the correct orientation (pleated media facing airflow direction as per unit label).
  5. Close the access door/grill securely. Restore power and reset any filter-service indicator if applicable.
  6. Schedule the next replacement in approximately 12 months (or sooner in heavy-smoke/dust environments).
  7. Good practice: also inspect and replace pre-filters every 3-4 weeks and the carbon V-bank filter every 8-12 months for optimal performance.

Frequently asked questions

Can I wash or clean this filter and reuse it?
No. The high-efficiency filter is not washable and must be replaced. Attempting to wash it will damage the media and void performance.

Is this filter compatible with other models besides MARK-20?
This filter is designed specifically for the MARK-20 commercial air cleaner.

How often should I replace it?
Under normal commercial usage, replace annually. If your environment is extremely heavy in smoke or dust, consider more frequent inspection.

Do I also need to replace the pre-filter or carbon filter at the same time?
Yes, while the high-efficiency filter is the final stage, your unit uses a three-stage system. The pre-filter and carbon filter should be replaced more frequently (pre-filter ~3-4 weeks; carbon filter ~8-12 months) to ensure the HEPA filter remains effective.

What happens if I delay changing the filter?
Delayed replacement can lead to reduced airflow, decreased capture efficiency of fine particles, increased load on the blower/motor, possibly higher operating cost and less effective smoke/odor removal.

Are there guidelines for disposing of the old filter?
Follow your local environmental and commercial-facility guidance for disposing used filters. Used filters may contain trapped contaminants (smoke, dust, fibers), so treat them as regular commercial waste or in accordance with facility procedures.

Does replacing the filter affect the warranty of my MARK-20 unit? The manufacturer states the lifetime warranty on the blower/motor requires filters to be changed as recommended and purchased from authorized supplier.
