Air Purifier Pre-Filters and Odor Filters

Genuine Honeywell Pre-Filters and Odor Filters

Help keep your Honeywell air purifier operating effectively with genuine Honeywell pre-filters and odor-reducing filters. These replacement filters provide an important first layer of filtration, capturing larger airborne particles before they reach the purifier’s primary filter.

Many Honeywell pre-filters also contain activated carbon that helps reduce unpleasant household odors and gases. Depending on the filter, this can include odors produced by pets, cooking, tobacco smoke, fireplaces and other common household sources.

What Does an Air Purifier Pre-Filter Do?

A pre-filter is generally installed in front of the air purifier’s primary HEPA or HEPA-type filter. As air enters the purifier, the pre-filter helps capture larger particles such as:

• Dust
• Pet hair
• Lint and fibers
• Larger airborne debris

Capturing these particles before they reach the primary filter can help the air purifier maintain its intended airflow and filtration performance.

Carbon Pre-Filters for Everyday Household Odors

Honeywell carbon pre-filters combine particle capture with activated carbon odor reduction. They are a practical choice for rooms affected by cooking smells, pets, tobacco smoke or other recurring household odors.

A carbon pre-filter does not replace the purifier’s primary HEPA or HEPA-type filter. The filters are designed to work together as part of the air purifier’s complete filtration system.

Enhanced Filters for Targeted Odor Reduction

Select Honeywell air purifiers can also use enhanced odor filters designed to address particular household concerns. Available options may target smoke, pet, kitchen or other persistent odors and volatile organic compounds.

Compatibility varies by air purifier. Review your owner’s manual or locate the model number and filter letters printed on your purifier before ordering an enhanced filter.

When Should a Pre-Filter Be Replaced?

Honeywell air purifier pre-filters should generally be replaced approximately every three months. Filters may need to be replaced more frequently in homes with pets, smokers, heavy dust, wildfire smoke or persistent cooking odors.

Check the pre-filter regularly and replace it when it becomes visibly dirty, clogged or no longer reduces odors effectively.

Find the Correct Filter for Your Air Purifier

Filter compatibility is determined by the air purifier model and required filter letter. Before purchasing, check the label located behind your purifier’s grille or consult its owner’s manual to confirm the correct replacement.

Using genuine Honeywell replacement filters helps ensure proper fit, airflow and performance for your compatible Honeywell air purifier.
