Honeywell U HEPA-Type Air Purifier Filter for HHT270 HHT290 — HEPA-type + Carbon Pre-filter, 1-Pack

Honeywell U HEPA-Type Filter for HHT270 and HHT290 is a certified replacement cartridge that captures dust, pollen, pet dander, smoke particles and reduces odors with a built-in carbon pre-filter.

This genuine Honeywell replacement filter is engineered to restore and maintain your HHT270 or HHT290 air purifier’s performance. It combines a HEPA-type filtration layer to trap microscopic particles with an activated carbon pre-filter to help neutralize common household odors. Replacing the filter on the recommended schedule keeps your purifier operating efficiently and helps maintain cleaner indoor air circulation.

How does this filter improve indoor air quality?

The U HEPA-Type Filter removes airborne particulates that commonly trigger sneezing, dust buildup, and stale smells. It filters particles 2 microns and larger from the air passing through the purifier and the carbon layer reduces odors from cooking, pets, and smoke. Use in the correct Honeywell models ensures the purifier can circulate filtered air as intended for the stated room size.

• HEPA-type layer captures dust, pollen, pet dander, smoke residue, and debris
• Carbon pre-filter adsorbs household odors and volatile compounds
• Designed for HHT270 and HHT290 to maintain certified airflow and CADR performance

How often should I replace the filter and why?

Honeywell recommends replacing the HEPA-type filter approximately three times per year under typical use. Frequent replacement preserves filtration efficiency and helps the purifier circulate air close to its rated capacity. If you have pets, smoke exposure, or high dust levels, check and replace the filter more often.

• Standard guideline: replace every 3 months for average households
• Replace sooner with pets, smokers, or heavy indoor activity
• Follow your purifier’s indicator or maintenance schedule for best results

Periodic inspection helps you spot visible dust loading or odor return, signaling an earlier replacement. Proper disposal and keeping replacement intervals consistent keep the purifier efficient.
