BISSELL air320 Air Purifier Filters: A Homeowner’s Guide
October 8, 2026
TL;DR
The BISSELL air320 runs on two replaceable filters, the 2804 HEPA and the 2677 carbon, with a washable fabric pre-filter in front of them. Plan on fresh filters about every six months, or sooner if you have pets or cook often. BISSELL advises against washing the HEPA or carbon filters, so once they load up, replacing them is the only fix.
Key Takeaways
The air320 has three filter stages: a fabric pre-filter, an H13 HEPA filter (part 2804), and an activated carbon filter (part 2677).
BISSELL recommends new air320 HEPA and carbon filters about every six months.
On the air320 display, F-1 means the HEPA filter and F-2 means the carbon filter.
Only the fabric pre-filter is washable. BISSELL does not recommend washing the HEPA or carbon filters.
What Filters Does The BISSELL air320 Use?
The BISSELL air320 uses three filter types. The fabric front panel doubles as the pre-filter and catches hair and larger dust. Behind it sit two more layers: a pleated H13 HEPA filter (BISSELL part 2804) for fine particles and an activated carbon filter (BISSELL part 2677) for household odors and volatile organic compounds (VOCs).
BISSELL rates the HEPA stage to capture 99.97% of particles 0.3 microns and smaller at the lowest fan speed, a rating built on the 99.97% at 0.3 microns benchmark in the U.S. Department of Energy HEPA filter specification. These filters fit only the BISSELL housing, not a furnace or central air return.

HEPA fibers trap particles but let gases pass through. That’s why the air320 adds a carbon layer, which holds odor and gas molecules in its pores.
Filterbuy has manufactured pleated air filters since 2013, and today we also build purifier filters that pair HEPA media with activated carbon. That filter maker’s lens shapes this guide: media quality and how long each layer stays clean.
BISSELL 2804 Vs. 2677: Which Replacement Filter Do You Need?
The BISSELL 2804 is the air320’s replacement HEPA filter, and the BISSELL 2677 is its replacement activated carbon filter. The two aren’t interchangeable, because one traps particles and the other holds odors and gases. BISSELL recommends changing them together.
Genuine parts are sold through BISSELL.com and major retailers. You can buy them separately, as the 3314 HEPA and carbon pack, or as the Pet Pro filter pack (3170). The 2677 also fits the smaller BISSELL air220, and the 3314 pack is listed for both the standard air320 (model 2768A) and the air320 Max (model 2847A).
Filterbuy’s Take: Swap both filters on the same day, even if only one code appears. With a single swap date, you reset once and always know how old each filter is.
Genuine Vs. Compatible air320 Filters: What To Check
Third-party air320 filters usually cost less than genuine BISSELL parts, but quality varies by brand, and a poor fit or thin media cuts performance. Before you buy, check three things.
HEPA grade: Look for True HEPA or H13 on the label. Filters sold as HEPA-type or HEPA-style are not held to the 99.97% standard.
Carbon content: Pick a carbon filter that lists its carbon by weight. The EPA notes that carbon filters work best with a large amount of carbon.
Fit and seal: Match part numbers 2804 and 2677, then make sure the frame sits flush. Any air that slips around a loose filter skips the media.
How Often Should You Change BISSELL air320 Filters?
BISSELL recommends changing air320 filters about every six months, but your home sets the real pace. Filter life depends on how many hours the purifier runs each day and how much dust, smoke, dander, and odor it pulls from the air.
Cost check: At BISSELL’s October 2026 list prices ($21.99 for the 2804 and $18.99 for the 2677), two filter sets a year come to about $82, or roughly 22 cents a day.
The EPA’s advice lines up with this: follow the manufacturer’s schedule, and change filters sooner if they look heavily soiled when you pull them out.
Guidance from Filterbuy. BISSELL's baseline is approximately six months.
What Are The Signs Your BISSELL air320 Filter Needs Replacing?
The clearest sign it’s time to change your BISSELL air320 filter is a flashing F-1 or F-2 code on the display. Filterbuy also recommends checking the filters themselves, since the indicator may not reflect their actual condition.
Cooking or pet odors linger longer than before.
Airflow from the top vent feels weaker at the same fan speed.
The HEPA filter pleats look gray or caked with dust.
How To Replace BISSELL air320 Filters
Replacing BISSELL air320 filters takes a few minutes, and you won’t need any tools.
Turn off and unplug the air320.
Remove the fabric front panel from the purifier.
Pull out the HEPA filter and the carbon filter. Note the position and direction of each one as you remove it.
Unwrap the new 2804 HEPA filter and 2677 carbon filter. Remove every piece of plastic packaging, because a wrapped filter blocks airflow.
Set each new filter in the same position and direction as the old one.
Reattach the fabric front panel and plug the purifier back in.
Reset the filter indicator (see the next section).
Filterbuy Pro Tip: Write the install date on each filter frame with a marker.
How To Reset The BISSELL air320 Filter Indicator
To reset the BISSELL air320 filter indicator, press and hold the power button for three seconds. You’ll hear a beep, and the F-1 and F-2 codes will clear from the display. Only reset after installing fresh filters, because the reset restarts the filter countdown.
Can You Wash Or Clean BISSELL air320 Filters?
You can clean the fabric pre-filter on the BISSELL air320, but keep the HEPA and carbon filters dry. BISSELL calls the front panel a washable pre-filter and says it does not recommend washing the filters, since water can damage HEPA fibers and clog carbon pores.
For routine cleaning, run a vacuum brush attachment over the panel to lift loose hair. If it needs a full wash, follow the air320 user guide and let the fabric dry completely. A damp panel can pass moisture to the HEPA media behind it.
The BISSELL air320 manual also calls for cleaning the sensor and screen every three months to keep PM2.5 readings accurate. For care tips on other purifier brands, see Filterbuy’s guide on how to choose air purifier replacement filters.

How Does The BISSELL air320 Work With Your HVAC Filter?
A BISSELL air320 cleans the air in one room. Your HVAC filter, by contrast, cleans the air moving through your whole home’s ductwork. BISSELL rates the air320 for rooms up to 366 square feet at 4.8 air changes per hour.
Filterbuy’s Take: Filterbuy MERV 13 filters are designed to last about 90 days, roughly half the air320’s six-month cycle. Change the air320 filters at every second HVAC filter change, and both layers stay on one calendar.
If you’re comparing purifiers, the AHAM Verifide directory of certified air cleaners lists tested CADR ratings and suggested room sizes.
A MERV 13 filter is not the same as a HEPA filter. MERV rates HVAC filters, while HEPA is a separate, higher efficiency standard, and Filterbuy’s breakdown of MERV 13 vs. HEPA filters for wildfire smoke explains when to use each. For home HVAC systems, the EPA guide to air cleaners in the home recommends a filter rated at least MERV 13, or as high as your system will accommodate.
When the AQI is over 100, Filterbuy recommends two steps:
If you have an HVAC system, switch to EPA-recommended MERV 13 air filters. Check your system’s manual first to confirm it supports MERV 13.
Run HEPA air purifiers, like the air320, in each room.
Follow current conditions on Filterbuy’s live air quality map. For whole-house odors, carbon air filters for your HVAC system add odor capture.

95 million U.S. households own a pet, according to the American Pet Products Association industry trends (2025 National Pet Owners Survey).
Filterbuy’s read: Poor air days and pets load filters faster, so watch for F-1 and F-2.
Keep Your Home’s Air On Schedule
Filterbuy’s air filter subscription ships HVAC filters every 30, 60, or 90 days. Pick 90 days and swap your air320 filters at every second delivery. Filterbuy also makes replacement filters for select air purifier models, shipped direct from the factory.
