Replacement Filters Compatible With Hamilton Beach Air Purifiers | Filterbuy
November 7, 2026
Every Hamilton Beach TrueAir purifier takes a specific filter, and the line has used at least six different parts, so the model number on your unit matters more than its shape or color. Filterbuy has built pleated air filters in its U.S. plants since 2013, so we read Hamilton Beach's specs the way a filter maker would: fit first, then media.
TL;DR
If you own a TrueAir 04383, 04383A, 04384 or 04386, you need the Hamilton Beach 990051000 permanent filter, which you vacuum instead of replacing on a schedule. The Hamilton Beach Air Purifier 20150 pairs reusable EverLasting filters with 22151 carbon filters that you swap every 3 months.
Key Takeaways
At Hamilton Beach's list prices, carbon refills run roughly $23 to $27 a year, and the 990051000 has no routine refill cost.
On the Air Purifier 20150, you vacuum the EverLasting filters once a year, and one 22151 carbon pack lasts 9 months.
When Filterbuy reviewed compatible listings in November 2026, depths for the same part varied by 0.8 inch, so measure before you order.
Which Filter Fits My Hamilton Beach Air Purifier?
Your model number decides which filter you need. The TrueAir compact models all take the 990051000, the TrueAir 04381 uses a 04712 pleated filter, and the chart below covers the rest of the line.
Sources: HamiltonBeach.com product pages for TrueAir air purifiers, the Air Purifier 20150, 22151 carbon filters and TrueAir odor eliminators, checked November 2026. The 04712, 04716 and 04912/04922 pairings come from retailer fit listings. Always confirm the model number on your unit before ordering.

How Do I Find My Hamilton Beach Model Number?
Hamilton Beach prints the model number on the rating label, usually on the bottom or back of the purifier. TrueAir model numbers tend to start with "04" and sometimes end in letters, as in 04383A or 04532GM. To find yours:
Unplug the purifier.
Find the rating label.
Write down the full model number, including any letters.
Check the old filter's frame for a part number, such as 990051000.
Match either number to the chart above.
“Choosing the right air filter shouldn't require an HVAC license. You deserve clear answers, practical advice, and the confidence that you're making the right choice for your home. My job is to take the guesswork out of cleaner air, so you can spend less time worrying about filters and more time enjoying your home.”
What Types of Filters Do Hamilton Beach Air Purifiers Use?
Most Hamilton Beach purifiers combine two kinds of filter. A pleated particle filter traps dust, pollen and pet dander, while an activated carbon filter absorbs odors. On many TrueAir models, the carbon pre-filter sits in front, so it catches larger debris and smells before air reaches the pleats.
Carbon filters don't trap fine dust on their own, and they stop absorbing odors once saturated.
Hamilton Beach calls its TrueAir filters HEPA-grade. As a filter maker, Filterbuy reads that as a description of how the filter is built rather than a tested rating. By the EPA definition, a True HEPA filter removes at least 99.97% of particles 0.3 microns in size. For the 20150, Hamilton Beach states that its EverLasting filters capture 99.9% of particles as small as 0.3 microns.
Filterbuy's guide to HEPA filter replacement types walks through them, and carbon vs. HEPA filter layers explains why each layer wears out on a separate schedule. Carbon also handles something particle media can't: it adsorbs some gases, including ground-level ozone.
How Often Should You Replace a Hamilton Beach Air Purifier Filter?
Plan to replace Hamilton Beach carbon filters every three months or so, or whenever the reminder light comes on. The pleated filters work differently. "Permanent" here means reusable, not forever, so vacuum the permanent and EverLasting filters on schedule and replace one once cleaning stops restoring airflow or the pleats tear.
Not sure a permanent filter is worn out? Try Filterbuy's 60-second check:
Vacuum both sides with a brush attachment.
Hold it up to a light. If no light comes through the pleats, replace it.
Run the unit on high. If airflow is still weak, replace it.
Check the frame and pleats. If either is bent or torn, replace it.
Pets and smoke wear filters out faster, and so does allergy season. If anyone at home reacts to pet dander or seasonal allergies, check the filter monthly, then weekly during wildfire smoke events. For layer-by-layer timing, see our guide on how often to replace air purifier filters.
What Does a Hamilton Beach Air Purifier Filter Cost per Year?
At Hamilton Beach's list prices, filters for these models cost less than $30 a year. Filterbuy calculated these from Hamilton Beach's prices and filter life.
Hamilton Beach list prices checked November 7, 2026. Yearly cost is our estimate from Hamilton Beach's stated filter life, before tax and shipping.
Maintenance is the cheapest filter you can buy; skip it, and a clogged permanent filter becomes an early $19.99 replacement.
What We Found Comparing Compatible Hamilton Beach Filter Listings
Fit is the part of a filter Filterbuy obsesses over, so in November 2026 we compared compatible Hamilton Beach listings against Hamilton Beach's specs. Three things stood out:
Sizes vary. Listings for 990051000-compatible filters listed three sizes: about 11.7 x 5 x 1.1 inches, 11.98 x 5.16 x 1 inches, and 11.5 x 5 x 1.8 inches.
Fit lists stretch. Several listings add the TrueAir 04385 to the 990051000 fit list, though Hamilton Beach doesn't. Another pairs the 04234G odor filter with the 04384 purifier, while Hamilton Beach lists it only for odor eliminators.
Labels get upgraded. Some listings advertise "H13 True HEPA," even though Hamilton Beach calls the original HEPA-grade. A stated capture rate at a stated particle size is the only label that tells you what a filter does.
Before buying, run the listing through Filterbuy's five-check framework for compatible purifier filters.
How to Replace a Hamilton Beach Air Purifier Filter
Swapping a Hamilton Beach filter takes a couple of minutes and no tools. On the 20150, the carbon filters sit behind magnetic covers on each side.
Unplug the air purifier.
Take off the front grille or filter door.
Slide out the old filter and any carbon pre-filter.
Vacuum loose dust out of the housing.
Insert the new filter with its arrow, if it has one, pointing toward the fan.
Lay the carbon pre-filter on the intake side, close the door, and reset the filter light.
Write the install date on the frame. At Filterbuy, we trust a date more than a timer.

How Filterbuy Can Help
Filterbuy doesn't make a Hamilton Beach-compatible filter yet. We only list a purifier filter once we can build it to fit. Right now our air purifier replacement filters cover GermGuardian Filter B, C and E, and our Cut Carbon pre-filters come pre-cut for GermGuardian and Honeywell purifiers.
Think beyond the purifier. A purifier cleans one room, while your HVAC filter cleans the whole house when the system runs (air filters vs. air purifiers). When the live USA AQI map climbs above 100, Filterbuy recommends two steps:
If you have an HVAC system, switch to an EPA-recommended MERV 13 filter.
Run HEPA air purifiers in each room.
Homes without ductwork can skip step 1. Air purifier vs. HVAC filter for outdoor pollution explains which device handles which pollutant.

Hamilton Beach Air Purifier Filter FAQs
Can I Wash My Hamilton Beach Air Purifier Filter?
Only if the owner's manual says it's washable. Water can damage pleated filter media, and it ruins activated carbon. Clean permanent and EverLasting filters with a vacuum brush attachment instead.
Are Compatible Filters as Good as Genuine Hamilton Beach Filters?
Some are and some aren't. Filterbuy only lists a filter once we can build it to fit, and we'd hold any seller to the same bar: exact dimensions, the matching part number, and a stated capture rate at a stated particle size.
Why Does My Purifier Still Smell After I Changed the Filter?
A lingering smell usually means the carbon filter is saturated or missing. Replace the carbon pre-filter, which lasts up to 90 days, and make sure it sits flat. Our guide on why your air purifier smells covers other causes.
Does Filterbuy Make Hamilton Beach Air Purifier Filters?
Not yet. Today Filterbuy makes GermGuardian replacement filters, plus Cut Carbon pre-filters for GermGuardian and Honeywell purifiers.
