About this product

HEPA Replacement Filter Optional Upgrade For Watchdog NXT60, NXT85, & NXT85C Dehumidifiers (3-Pack)

This Watchdog HEPA filter is an optional upgrade that replaces the MERV-10 filter that comes standard in NXT60, NXT85, and NXT85C dehumidifiers. HEPA filters are extremely effective at removing the smallest particles from the air. 

Recommended replacement is every 12 months.

For use in the following Seaira Global Watchdog NXT dehumidifiers:

Best for

  • Improving airborne particle capture in WatchDog NXT Series dehumidifiers
  • Crawl spaces, basements, and whole‑home installs where fine dust is a concern (near workshops, unpaved drives, or seasonal pollen surges)
  • Commercial spaces, grow rooms, offices, and living areas where dust and fine particulates are a concern
  • Environments that benefit from enhanced filtration beyond standard dehumidifier intake screens
  • Facilities that want cleaner air while controlling humidity
  • Maintenance teams seeking a convenient multi-pack solution

  • Remove Existing Filter or Screen: Take out the old filter or dust screen if present.
  • Insert HEPA Upgrade Filter: Place the HEPA cartridge in the designated slot, ensuring correct orientation.

  • Routine Replacement: Replace with a fresh HEPA filter when airflow resistance increases or per maintenance schedule.

Frequently asked questions

How often should I replace the HEPA?
Plan on about 12 months in typical homes; dusty environments may need earlier changes. Always inspect at least annually.

Is HEPA washable?
No. The HEPA filter is non‑washable—replace when loaded or when airflow drops despite a clean pre‑filter. 

How does this compare to the carbon filter upgrade?
HEPA targets fine particles; carbon targets odors/VOCs. Many customers run HEPA for dust seasons and carbon when odor control matters most.

Can I run my dehumidifier with the HEPA installed all the time?
Yes. The HEPA filter is designed for continuous use; just monitor airflow and replace as needed.

Will this fit NXT‑60 with internal pump (600c)?

Yes, the HEPA filter upgrade will fit a WatchDog NXT-60 with the internal pump (600c) as long as you’re ordering the correct N-202 size (12″ × 10″ × 0.75″) and it replaces the existing MERV-10 filter behind the pre-filter.
