For today’s review, we’re going to dive into another air purifier, the Bulex air purifier. The Bulex AF-3222 brings a simple modern look to the traditional air purifier. It’s small and lightweight, yet powerful enough to treat up to 202 sf.

There’s more to know so let’s go ahead and get started!

Small, but Mighty Air Purifier


Bulex Air Purifier

The Bulex air purifier is a medium-sized air purifier with 4-stage filtration (including carbon filter), touch panel controls, 4 fan speeds, and a sleep mode. It has a modern black aesthetic and excellent performance, making it a solid option for small to medium sized rooms (up to 202 sf.). During our tests it was able to achieve an air quality index of 0 and PM2.5 level of 0.4. Check Price


  • Great for small bedrooms or home offices
  • Max fan speed allows for up to 4 air changes in an hour
  • Lifetime warranty and replacement


  • Doesn’t have an auto mode or air quality detection sensors

The Bulex air purifier is made of a black plastic composite with a matte feel. The air intake grill is at the base with the filtration within the housing, and the air outlet located at the top.

The wide air intake allows this purifier to perform 4 air changes in one hour and can treat up to 202 square feet of air space.

  • Adjust fan speed: select from sleep mode, low, medium, or high
  • Timer: set a timer, ranging from 2 hours up to 8 hours
  • LED light: turns the lights on or off
  • Filter replacement: there is also a filtration replacement notification, which will alert you when it’s time to replace the filter

How does it clean the air?

This Bulex air purifier cleans the air by using a 4-stage filtration system.

  • Pre-Filter: The pre-filter removes larger particles like dust hair or other fibers from the air.
  • HEPA Filter: The HEPA filter captures smaller particulates like pollen and other allergens. At peak performance, a HEPA filter can remove 99.97% of particles as small as 0.3 microns.
  • Carbon filter: The carbon filter is designed to remove odors (like smoke or cooking), as well as other harmful airborne chemicals like benzene and formaldehyde.
  • Degerming filter: This filter sterilizing the air as it’s coming back into the room.

How big is the Bulex?

The Bulex air purifier is a pretty compact air purifier. It has a round, cylindrical base that can sit on the floor or upright on a large table.

Using the Bulex Purifier

Setting up and using the Bulex air purifier is simple and easy to get started. This air purifier lacks smart control so it’s quick to setup.

To setup the Bulex air purifier for the first time:

  1. Unbox the unit.
  2. Remove all packaging.
  3. Make sure all filters are installed properly.
  4. Turn the unit on.

The Bulex air purifier doesn’t have an “auto mode” so you’ll need to select your fan speed manually.

You can choose from low, medium, high, or quiet. I will say that in quiet mode, this air purifier was incredibly quiet. The fact that the lights dim as well as a nice feature if you’re looking for a discreet air purifier.


Maintenance of the Bulex really is as simple as replacing the filters when needed. Since this purifier will tell you when it’s time to replace, it’s a pretty easy process.

Regular replacement of filters keeps the purifier sensors and filtration working at peak performance.

Bulex Performance

For the price, I would say that the Bulex air purifier had surprisingly good performance. It was able to make a noticeable impact on air quality and get the overall Air Quality Index down to 0.

What were the results?

Starting Baseline

  • PM2.5: 4.5
  • PM10: 6.9
  • Particles: 339
  • AQI: 18

After 1 Hour

  • PM2.5: 0.4
  • PM10: 0.7
  • Particles: 69
  • AQI: 0

After an hour, the Bulex air purifier removed 80% of air particles from the medium-sized room we tested in (~12×12′). It was able to improve PM2.5 air quality by 88%.

Is the Bulex worth it?

All things considered, is the Bulex air purifier worth it? I would say that the Bulex is absolutely a good value and worth the money. It looks nice, is easy to use, has great purification performance, and some other cool specs.

Top features include:

  • Sleep mode
  • Variable fan speeds
  • 4-stage filtration
  • Good area coverage (up to 202 sf)

The one thing that it did lack that I would like to have seen is an auto mode. An air purifier that can detect when it needs to increase fan speed is a really nice bonus and certainly would add to the value of the Bulex.

Should You Buy the Bulex?

So the big question remains — should you buy the Bulex? It’s sleek, intuitive, and gets the job done.

I would recommend the Bulex AF 3222 if you’re looking for the following in an air purifier:

  • Great performance: For its size and price, the performance on the Bulex is great. It was able to notably improve the air quality in the medium-sized room we tested in.
  • Easy to use: The Bulex doesn’t have wifi connectivity so that means no app-based controls or smartphone data reports. It has a few touch controls directly on the unit that make it easy to adjust fan speed based, as needed.
  • Don’t need auto mode: Fancier air purifiers have an “auto mode” that allows the purifier to detect current air quality and adjust fan speed as needed to keep the air as clean as possible. If this isn’t an important feature, then the simple design of the Bulex could be an excellent option.

  1. How often should I be replacing the Hepa filter. Should I replace the carbon filter, and where is the carbon filter. The hepa filter looks clean.

    • Every 6-12 months depending on usage and how bad the air quality in your home is.

      HEPA and carbon filters are integrated together on this unit.

      If it still looks clean then you can get more life out of the filter.

  2. I would love to win because my breathing is terrible. I have asthma and ABPA (severe allergies). I wear a bipap and oxygen almost 24/7 snd rarely go out. This would sure be a blessing! Thanks for the chance.
