At a Glance
- Fits BAPT01 and BAPT02: the genuine filter for both purifiers
- 3 stages in one: pre-filter, HEPA, and activated carbon
- 99.97% at 0.3 microns: captures fine dust, pollen, and dander

A tired filter quietly turns a good purifier into a fan. The BLACK+DECKER AF1 is the genuine replacement for the BAPT01 and BAPT02 tabletop purifiers, combining three stages in one drop-in cartridge. The pre-filter catches dust and pet hair, the HEPA layer captures 99.97% of particles as small as 0.3 microns, and activated carbon cuts odors from cooking and smoke. Swap it in about every 2,000 hours and your purifier keeps doing its job.
Key Features
- Made for BAPT01 and BAPT02: the matched replacement for both BLACK+DECKER tabletop purifiers.
- Pre-filter stage: traps larger particles like dust, lint, and pet hair first.
- HEPA stage: captures 99.97% of particles as small as 0.3 microns, including pollen and dust mite debris.
- Activated carbon stage: absorbs odors such as cigarette smoke and cooking smells.
- About 2,000 hours of use: replace sooner if the air is very smoky or the filter looks dirty.
What's Included
In the box: one AF1 3-stage replacement filter and an instruction sheet.
Before You Buy
- It fits the BAPT01 and BAPT02 only. Check the model label on your purifier before ordering. The AF1 is not made for other BLACK+DECKER purifiers or other brands.

Why a fresh AF1 matters
HEPA capture restored
As a filter loads up, airflow drops and cleaning slows. A new AF1 brings back 99.97% capture of particles down to 0.3 microns, so pollen, dander, and fine dust get trapped again.
Odors handled again
Activated carbon fills up over time and stops absorbing smells. Fresh carbon in the AF1 takes on cooking odors and smoke once more, which is often the first change you will notice.
The AF1 by the numbers
One filter, three stages, months of everyday use.

Typical service life
How does the genuine AF1 compare?
vs. a generic look-alike filter
The AF1 is made by BLACK+DECKER for the BAPT01 and BAPT02, so the fit and the 3-stage design match what the purifier was built around.
vs. vacuuming the old filter
Vacuuming does not restore a HEPA layer or recharge spent carbon. Replacing it does.
vs. running past the alert
A clogged filter moves less air and lets odors linger. A fresh AF1 brings back full airflow and odor control.

- Filter
- 6.9 in W x 6.9 in D x 5.9 in H
